+layout: code-of-conduct
+version: v1.0
+---
+
+This code of conduct outlines our expectations for participants within the **NYTimes/gziphandler** community, as well as steps to reporting unacceptable behavior. We are committed to providing a welcoming and inspiring community for all and expect our code of conduct to be honored. Anyone who violates this code of conduct may be banned from the community.
+
+Our open source community strives to:
+
+* **Be friendly and patient.**
+* **Be welcoming**: We strive to be a community that welcomes and supports people of all backgrounds and identities. This includes, but is not limited to members of any race, ethnicity, culture, national origin, colour, immigration status, social and economic class, educational level, sex, sexual orientation, gender identity and expression, age, size, family status, political belief, religion, and mental and physical ability.
+* **Be considerate**: Your work will be used by other people, and you in turn will depend on the work of others. Any decision you take will affect users and colleagues, and you should take those consequences into account when making decisions. Remember that we're a world-wide community, so you might not be communicating in someone else's primary language.
+* **Be respectful**:  Not all of us will agree all the time, but disagreement is no excuse for poor behavior and poor manners. We might all experience some frustration now and then, but we cannot allow that frustration to turn into a personal attack. It’s important to remember that a community where people feel uncomfortable or threatened is not a productive one.
+* **Be careful in the words that we choose**: we are a community of professionals, and we conduct ourselves professionally. Be kind to others. Do not insult or put down other participants. Harassment and other exclusionary behavior aren't acceptable.
+* **Try to understand why we disagree**: Disagreements, both social and technical, happen all the time. It is important that we resolve disagreements and differing views constructively. Remember that we’re different. The strength of our community comes from its diversity, people from a wide range of backgrounds. Different people have different perspectives on issues. Being unable to understand why someone holds a viewpoint doesn’t mean that they’re wrong. Don’t forget that it is human to err and blaming each other doesn’t get us anywhere. Instead, focus on helping to resolve issues and learning from mistakes.
+
+## Definitions
+
+Harassment includes, but is not limited to:
+
+- Offensive comments related to gender, gender identity and expression, sexual orientation, disability, mental illness, neuro(a)typicality, physical appearance, body size, race, age, regional discrimination, political or religious affiliation
+- Unwelcome comments regarding a person’s lifestyle choices and practices, including those related to food, health, parenting, drugs, and employment
+- Deliberate misgendering. This includes deadnaming or persistently using a pronoun that does not correctly reflect a person's gender identity. You must address people by the name they give you when not addressing them by their username or handle
+- Physical contact and simulated physical contact (eg, textual descriptions like “*hug*” or “*backrub*”) without consent or after a request to stop
+- Threats of violence, both physical and psychological
+- Incitement of violence towards any individual, including encouraging a person to commit suicide or to engage in self-harm
+- Deliberate intimidation
+- Stalking or following
+- Harassing photography or recording, including logging online activity for harassment purposes
+- Sustained disruption of discussion
+- Unwelcome sexual attention, including gratuitous or off-topic sexual images or behaviour
+- Pattern of inappropriate social contact, such as requesting/assuming inappropriate levels of intimacy with others
+- Continued one-on-one communication after requests to cease
+- Deliberate “outing” of any aspect of a person’s identity without their consent except as necessary to protect others from intentional abuse
+- Publication of non-harassing private communication
+
+Our open source community prioritizes marginalized people’s safety over privileged people’s comfort. We will not act on complaints regarding:
+
+- ‘Reverse’ -isms, including ‘reverse racism,’ ‘reverse sexism,’ and ‘cisphobia’
+- Reasonable communication of boundaries, such as “leave me alone,” “go away,” or “I’m not discussing this with you”
+- Refusal to explain or debate social justice concepts
+- Communicating in a ‘tone’ you don’t find congenial
+- Criticizing racist, sexist, cissexist, or otherwise oppressive behavior or assumptions
+
+
+### Diversity Statement
+
+We encourage everyone to participate and are committed to building a community for all. Although we will fail at times, we seek to treat everyone both as fairly and equally as possible. Whenever a participant has made a mistake, we expect them to take responsibility for it. If someone has been harmed or offended, it is our responsibility to listen carefully and respectfully, and do our best to right the wrong.
+
+Although this list cannot be exhaustive, we explicitly honor diversity in age, gender, gender identity or expression, culture, ethnicity, language, national origin, political beliefs, profession, race, religion, sexual orientation, socioeconomic status, and technical ability. We will not tolerate discrimination based on any of the protected
+characteristics above, including participants with disabilities.
+
+### Reporting Issues
+
+If you experience or witness unacceptable behavior—or have any other concerns—please report it by contacting us via **code@nytimes.com**. All reports will be handled with discretion. In your report please include:
+
+- Your contact information.
+- Names (real, nicknames, or pseudonyms) of any individuals involved. If there are additional witnesses, please
+include them as well. Your account of what occurred, and if you believe the incident is ongoing. If there is a publicly available record (e.g. a mailing list archive or a public IRC logger), please include a link.
+- Any additional information that may be helpful.
+
+After filing a report, a representative will contact you personally, review the incident, follow up with any additional questions, and make a decision as to how to respond. If the person who is harassing you is part of the response team, they will recuse themselves from handling your incident. If the complaint originates from a member of the response team, it will be handled by a different member of the response team. We will respect confidentiality requests for the purpose of protecting victims of abuse.
+

+Gzip Handler
+============
+
+This is a tiny Go package which wraps HTTP handlers to transparently gzip the
+response body, for clients which support it. Although it's usually simpler to
+leave that to a reverse proxy (like nginx or Varnish), this package is useful
+when that's undesirable.
+
+
+## Usage
+
+Call `GzipHandler` with any handler (an object which implements the
+`http.Handler` interface), and it'll return a new handler which gzips the
+response. For example:
+
+```go
+package main
+
+import (
+	"io"
+	"net/http"
+	"github.com/NYTimes/gziphandler"
+)
+
+func main() {
+	withoutGz := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+		w.Header().Set("Content-Type", "text/plain")
+		io.WriteString(w, "Hello, World")
+	})
+
+	withGz := gziphandler.GzipHandler(withoutGz)
+
+	http.Handle("/", withGz)
+	http.ListenAndServe("0.0.0.0:8000", nil)
+}
+```
+

+# Purell
+
+Purell is a tiny Go library to normalize URLs. It returns a pure URL. Pure-ell. Sanitizer and all. Yeah, I know...
+
+Based on the [wikipedia paper][wiki] and the [RFC 3986 document][rfc].
+
+[![build status](https://secure.travis-ci.org/PuerkitoBio/purell.png)](http://travis-ci.org/PuerkitoBio/purell)
+
+## Install
+
+`go get github.com/PuerkitoBio/purell`
+
+## Changelog
+
+*    **2016-11-14 (v1.1.0)** : IDN: Conform to RFC 5895: Fold character width (thanks to @beeker1121).
+*    **2016-07-27 (v1.0.0)** : Normalize IDN to ASCII (thanks to @zenovich).
+*    **2015-02-08** : Add fix for relative paths issue ([PR #5][pr5]) and add fix for unnecessary encoding of reserved characters ([see issue #7][iss7]).
+*    **v0.2.0** : Add benchmarks, Attempt IDN support.
+*    **v0.1.0** : Initial release.
+
+## Examples
+
+From `example_test.go` (note that in your code, you would import "github.com/PuerkitoBio/purell", and would prefix references to its methods and constants with "purell."):
+
+```go
+package purell
+
+import (
+  "fmt"
+  "net/url"
+)
+
+func ExampleNormalizeURLString() {
+  if normalized, err := NormalizeURLString("hTTp://someWEBsite.com:80/Amazing%3f/url/",
+    FlagLowercaseScheme|FlagLowercaseHost|FlagUppercaseEscapes); err != nil {
+    panic(err)
+  } else {
+    fmt.Print(normalized)
+  }
+  // Output: http://somewebsite.com:80/Amazing%3F/url/
+}
+
+func ExampleMustNormalizeURLString() {
+  normalized := MustNormalizeURLString("hTTpS://someWEBsite.com:443/Amazing%fa/url/",
+    FlagsUnsafeGreedy)
+  fmt.Print(normalized)
+
+  // Output: http://somewebsite.com/Amazing%FA/url
+}
+
+func ExampleNormalizeURL() {
+  if u, err := url.Parse("Http://SomeUrl.com:8080/a/b/.././c///g?c=3&a=1&b=9&c=0#target"); err != nil {
+    panic(err)
+  } else {
+    normalized := NormalizeURL(u, FlagsUsuallySafeGreedy|FlagRemoveDuplicateSlashes|FlagRemoveFragment)
+    fmt.Print(normalized)
+  }
+
+  // Output: http://someurl.com:8080/a/c/g?c=3&a=1&b=9&c=0
+}
+```
+
+## API
+
+As seen in the examples above, purell offers three methods, `NormalizeURLString(string, NormalizationFlags) (string, error)`, `MustNormalizeURLString(string, NormalizationFlags) (string)` and `NormalizeURL(*url.URL, NormalizationFlags) (string)`. They all normalize the provided URL based on the specified flags. Here are the available flags:
+
+```go
+const (
+	// Safe normalizations
+	FlagLowercaseScheme           NormalizationFlags = 1 << iota // HTTP://host -> http://host, applied by default in Go1.1
+	FlagLowercaseHost                                            // http://HOST -> http://host
+	FlagUppercaseEscapes                                         // http://host/t%ef -> http://host/t%EF
+	FlagDecodeUnnecessaryEscapes                                 // http://host/t%41 -> http://host/tA
+	FlagEncodeNecessaryEscapes                                   // http://host/!"#$ -> http://host/%21%22#$
+	FlagRemoveDefaultPort                                        // http://host:80 -> http://host
+	FlagRemoveEmptyQuerySeparator                                // http://host/path? -> http://host/path
+
+	// Usually safe normalizations
+	FlagRemoveTrailingSlash // http://host/path/ -> http://host/path
+	FlagAddTrailingSlash    // http://host/path -> http://host/path/ (should choose only one of these add/remove trailing slash flags)
+	FlagRemoveDotSegments   // http://host/path/./a/b/../c -> http://host/path/a/c
+
+	// Unsafe normalizations
+	FlagRemoveDirectoryIndex   // http://host/path/index.html -> http://host/path/
+	FlagRemoveFragment         // http://host/path#fragment -> http://host/path
+	FlagForceHTTP              // https://host -> http://host
+	FlagRemoveDuplicateSlashes // http://host/path//a///b -> http://host/path/a/b
+	FlagRemoveWWW              // http://www.host/ -> http://host/
+	FlagAddWWW                 // http://host/ -> http://www.host/ (should choose only one of these add/remove WWW flags)
+	FlagSortQuery              // http://host/path?c=3&b=2&a=1&b=1 -> http://host/path?a=1&b=1&b=2&c=3
+
+	// Normalizations not in the wikipedia article, required to cover tests cases
+	// submitted by jehiah
+	FlagDecodeDWORDHost           // http://1113982867 -> http://66.102.7.147
+	FlagDecodeOctalHost           // http://0102.0146.07.0223 -> http://66.102.7.147
+	FlagDecodeHexHost             // http://0x42660793 -> http://66.102.7.147
+	FlagRemoveUnnecessaryHostDots // http://.host../path -> http://host/path
+	FlagRemoveEmptyPortSeparator  // http://host:/path -> http://host/path
+
+	// Convenience set of safe normalizations
+	FlagsSafe NormalizationFlags = FlagLowercaseHost | FlagLowercaseScheme | FlagUppercaseEscapes | FlagDecodeUnnecessaryEscapes | FlagEncodeNecessaryEscapes | FlagRemoveDefaultPort | FlagRemoveEmptyQuerySeparator
+
+	// For convenience sets, "greedy" uses the "remove trailing slash" and "remove www. prefix" flags,
+	// while "non-greedy" uses the "add (or keep) the trailing slash" and "add www. prefix".
+
+	// Convenience set of usually safe normalizations (includes FlagsSafe)
+	FlagsUsuallySafeGreedy    NormalizationFlags = FlagsSafe | FlagRemoveTrailingSlash | FlagRemoveDotSegments
+	FlagsUsuallySafeNonGreedy NormalizationFlags = FlagsSafe | FlagAddTrailingSlash | FlagRemoveDotSegments
+
+	// Convenience set of unsafe normalizations (includes FlagsUsuallySafe)
+	FlagsUnsafeGreedy    NormalizationFlags = FlagsUsuallySafeGreedy | FlagRemoveDirectoryIndex | FlagRemoveFragment | FlagForceHTTP | FlagRemoveDuplicateSlashes | FlagRemoveWWW | FlagSortQuery
+	FlagsUnsafeNonGreedy NormalizationFlags = FlagsUsuallySafeNonGreedy | FlagRemoveDirectoryIndex | FlagRemoveFragment | FlagForceHTTP | FlagRemoveDuplicateSlashes | FlagAddWWW | FlagSortQuery
+
+	// Convenience set of all available flags
+	FlagsAllGreedy    = FlagsUnsafeGreedy | FlagDecodeDWORDHost | FlagDecodeOctalHost | FlagDecodeHexHost | FlagRemoveUnnecessaryHostDots | FlagRemoveEmptyPortSeparator
+	FlagsAllNonGreedy = FlagsUnsafeNonGreedy | FlagDecodeDWORDHost | FlagDecodeOctalHost | FlagDecodeHexHost | FlagRemoveUnnecessaryHostDots | FlagRemoveEmptyPortSeparator
+)
+```
+
+For convenience, the set of flags `FlagsSafe`, `FlagsUsuallySafe[Greedy|NonGreedy]`, `FlagsUnsafe[Greedy|NonGreedy]` and `FlagsAll[Greedy|NonGreedy]` are provided for the similarly grouped normalizations on [wikipedia's URL normalization page][wiki]. You can add (using the bitwise OR `|` operator) or remove (using the bitwise AND NOT `&^` operator) individual flags from the sets if required, to build your own custom set.
+
+The [full godoc reference is available on gopkgdoc][godoc].
+
+Some things to note:
+
+*    `FlagDecodeUnnecessaryEscapes`, `FlagEncodeNecessaryEscapes`, `FlagUppercaseEscapes` and `FlagRemoveEmptyQuerySeparator` are always implicitly set, because internally, the URL string is parsed as an URL object, which automatically decodes unnecessary escapes, uppercases and encodes necessary ones, and removes empty query separators (an unnecessary `?` at the end of the url). So this operation cannot **not** be done. For this reason, `FlagRemoveEmptyQuerySeparator` (as well as the other three) has been included in the `FlagsSafe` convenience set, instead of `FlagsUnsafe`, where Wikipedia puts it.
+
+*    The `FlagDecodeUnnecessaryEscapes` decodes the following escapes (*from -> to*):
+    -    %24 -> $
+    -    %26 -> &
+    -    %2B-%3B -> +,-./0123456789:;
+    -    %3D -> =
+    -    %40-%5A -> @ABCDEFGHIJKLMNOPQRSTUVWXYZ
+    -    %5F -> _
+    -    %61-%7A -> abcdefghijklmnopqrstuvwxyz
+    -    %7E -> ~
+
+
+*    When the `NormalizeURL` function is used (passing an URL object), this source URL object is modified (that is, after the call, the URL object will be modified to reflect the normalization).
+
+*    The *replace IP with domain name* normalization (`http://208.77.188.166/ → http://www.example.com/`) is obviously not possible for a library without making some network requests. This is not implemented in purell.
+
+*    The *remove unused query string parameters* and *remove default query parameters* are also not implemented, since this is a very case-specific normalization, and it is quite trivial to do with an URL object.
+
+### Safe vs Usually Safe vs Unsafe
+
+Purell allows you to control the level of risk you take while normalizing an URL. You can aggressively normalize, play it totally safe, or anything in between.
+
+Consider the following URL:
+
+`HTTPS://www.RooT.com/toto/t%45%1f///a/./b/../c/?z=3&w=2&a=4&w=1#invalid`
+
+Normalizing with the `FlagsSafe` gives:
+
+`https://www.root.com/toto/tE%1F///a/./b/../c/?z=3&w=2&a=4&w=1#invalid`
+
+With the `FlagsUsuallySafeGreedy`:
+
+`https://www.root.com/toto/tE%1F///a/c?z=3&w=2&a=4&w=1#invalid`
+
+And with `FlagsUnsafeGreedy`:
+
+`http://root.com/toto/tE%1F/a/c?a=4&w=1&w=2&z=3`
+
+## TODOs
+
+*    Add a class/default instance to allow specifying custom directory index names? At the moment, removing directory index removes `(^|/)((?:default|index)\.\w{1,4})$`.

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,

+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+
+   3. Grant of Patent License. Subject to the terms and conditions of

+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+# etcd/client
+
+etcd/client is the Go client library for etcd.
+
+[![GoDoc](https://godoc.org/github.com/coreos/etcd/client?status.png)](https://godoc.org/github.com/coreos/etcd/client)
+
+etcd uses `cmd/vendor` directory to store external dependencies, which are
+to be compiled into etcd release binaries. `client` can be imported without
+vendoring. For full compatibility, it is recommended to vendor builds using
+etcd's vendored packages, using tools like godep, as in
+[vendor directories](https://golang.org/cmd/go/#hdr-Vendor_Directories).
+For more detail, please read [Go vendor design](https://golang.org/s/go15vendor).
+
+## Install
+
+```bash
+go get github.com/coreos/etcd/client
+```
+
+## Usage
+
+```go
+package main
+
+import (
+	"log"
+	"time"
+	"context"
+
+	"github.com/coreos/etcd/client"
+)
+
+func main() {
+	cfg := client.Config{
+		Endpoints:               []string{"http://127.0.0.1:2379"},
+		Transport:               client.DefaultTransport,
+		// set timeout per request to fail fast when the target endpoint is unavailable
+		HeaderTimeoutPerRequest: time.Second,
+	}
+	c, err := client.New(cfg)
+	if err != nil {
+		log.Fatal(err)
+	}
+	kapi := client.NewKeysAPI(c)
+	// set "/foo" key with "bar" value
+	log.Print("Setting '/foo' key with 'bar' value")
+	resp, err := kapi.Set(context.Background(), "/foo", "bar", nil)
+	if err != nil {
+		log.Fatal(err)
+	} else {
+		// print common key info
+		log.Printf("Set is done. Metadata is %q\n", resp)
+	}
+	// get "/foo" key's value
+	log.Print("Getting '/foo' key value")
+	resp, err = kapi.Get(context.Background(), "/foo", nil)
+	if err != nil {
+		log.Fatal(err)
+	} else {
+		// print common key info
+		log.Printf("Get is done. Metadata is %q\n", resp)
+		// print value
+		log.Printf("%q key has %q value\n", resp.Node.Key, resp.Node.Value)
+	}
+}
+```
+
+## Error Handling
+
+etcd client might return three types of errors.
+
+- context error
+
+Each API call has its first parameter as `context`. A context can be canceled or have an attached deadline. If the context is canceled or reaches its deadline, the responding context error will be returned no matter what internal errors the API call has already encountered.
+
+- cluster error
+
+Each API call tries to send request to the cluster endpoints one by one until it successfully gets a response. If a requests to an endpoint fails, due to exceeding per request timeout or connection issues, the error will be added into a list of errors. If all possible endpoints fail, a cluster error that includes all encountered errors will be returned.
+
+- response error
+
+If the response gets from the cluster is invalid, a plain string error will be returned. For example, it might be a invalid JSON error.
+
+Here is the example code to handle client errors:
+
+```go
+cfg := client.Config{Endpoints: []string{"http://etcd1:2379","http://etcd2:2379","http://etcd3:2379"}}
+c, err := client.New(cfg)
+if err != nil {
+	log.Fatal(err)
+}
+
+kapi := client.NewKeysAPI(c)
+resp, err := kapi.Set(ctx, "test", "bar", nil)
+if err != nil {
+	if err == context.Canceled {
+		// ctx is canceled by another routine
+	} else if err == context.DeadlineExceeded {
+		// ctx is attached with a deadline and it exceeded
+	} else if cerr, ok := err.(*client.ClusterError); ok {
+		// process (cerr.Errors)
+	} else {
+		// bad cluster endpoints, which are not etcd servers
+	}
+}
+```
+
+
+## Caveat
+
+1. etcd/client prefers to use the same endpoint as long as the endpoint continues to work well. This saves socket resources, and improves efficiency for both client and server side. This preference doesn't remove consistency from the data consumed by the client because data replicated to each etcd member has already passed through the consensus process.
+
+2. etcd/client does round-robin rotation on other available endpoints if the preferred endpoint isn't functioning properly. For example, if the member that etcd/client connects to is hard killed, etcd/client will fail on the first attempt with the killed member, and succeed on the second attempt with another member. If it fails to talk to all available endpoints, it will return all errors happened.
+
+3. Default etcd/client cannot handle the case that the remote server is SIGSTOPed now. TCP keepalive mechanism doesn't help in this scenario because operating system may still send TCP keep-alive packets. Over time we'd like to improve this functionality, but solving this issue isn't high priority because a real-life case in which a server is stopped, but the connection is kept alive, hasn't been brought to our attention.
+
+4. etcd/client cannot detect whether a member is healthy with watches and non-quorum read requests. If the member is isolated from the cluster, etcd/client may retrieve outdated data. Instead, users can either issue quorum read requests or monitor the /health endpoint for member health information.

+
+	// create a new key /foo with the value "bar"
+	_, err = kAPI.Create(context.Background(), "/foo", "bar")

+	_, err = kAPI.Delete(context.Background(), "/foo", &DeleteOptions{PrevValue: "bar"})

+# etcd/clientv3
+
+[![Godoc](https://img.shields.io/badge/go-documentation-blue.svg?style=flat-square)](https://godoc.org/github.com/coreos/etcd/clientv3)
+
+`etcd/clientv3` is the official Go etcd client for v3.
+
+## Install
+
+```bash
+go get github.com/coreos/etcd/clientv3
+```
+
+## Get started
+
+Create client using `clientv3.New`:
+
+```go
+cli, err := clientv3.New(clientv3.Config{
+	Endpoints:   []string{"localhost:2379", "localhost:22379", "localhost:32379"},
+	DialTimeout: 5 * time.Second,
+})
+if err != nil {
+	// handle error!
+}
+defer cli.Close()
+```
+
+etcd v3 uses [`gRPC`](http://www.grpc.io) for remote procedure calls. And `clientv3` uses
+[`grpc-go`](https://github.com/grpc/grpc-go) to connect to etcd. Make sure to close the client after using it. 
+If the client is not closed, the connection will have leaky goroutines. To specify client request timeout,
+pass `context.WithTimeout` to APIs:
+
+```go
+ctx, cancel := context.WithTimeout(context.Background(), timeout)
+resp, err := cli.Put(ctx, "sample_key", "sample_value")
+cancel()
+if err != nil {
+    // handle error!
+}
+// use the response
+```
+
+etcd uses `cmd/vendor` directory to store external dependencies, which are
+to be compiled into etcd release binaries. `client` can be imported without
+vendoring. For full compatibility, it is recommended to vendor builds using
+etcd's vendored packages, using tools like godep, as in
+[vendor directories](https://golang.org/cmd/go/#hdr-Vendor_Directories).
+For more detail, please read [Go vendor design](https://golang.org/s/go15vendor).
+
+## Error Handling
+
+etcd client returns 2 types of errors:
+
+1. context error: canceled or deadline exceeded.
+2. gRPC error: see [api/v3rpc/rpctypes](https://godoc.org/github.com/coreos/etcd/etcdserver/api/v3rpc/rpctypes).
+
+Here is the example code to handle client errors:
+
+```go
+resp, err := cli.Put(ctx, "", "")
+if err != nil {
+	switch err {
+	case context.Canceled:
+		log.Fatalf("ctx is canceled by another routine: %v", err)
+	case context.DeadlineExceeded:
+		log.Fatalf("ctx is attached with a deadline is exceeded: %v", err)
+	case rpctypes.ErrEmptyKey:
+		log.Fatalf("client-side error: %v", err)
+	default:
+		log.Fatalf("bad cluster endpoints, which are not etcd servers: %v", err)
+	}
+}
+```
+
+## Metrics
+
+The etcd client optionally exposes RPC metrics through [go-grpc-prometheus](https://github.com/grpc-ecosystem/go-grpc-prometheus). See the [examples](https://github.com/coreos/etcd/blob/master/clientv3/example_metrics_test.go).
+
+## Namespacing
+
+The [namespace](https://godoc.org/github.com/coreos/etcd/clientv3/namespace) package provides `clientv3` interface wrappers to transparently isolate client requests to a user-defined prefix.
+
+## Examples
+
+More code examples can be found at [GoDoc](https://godoc.org/github.com/coreos/etcd/clientv3).

+// and consists of three components:
+// 1. A list of tests called guard. Each test in guard checks a single entry in the database. It may check
+// for the absence or presence of a value, or compare with a given value. Two different tests in the guard
+// may apply to the same or different entries in the database. All tests in the guard are applied and
+// MultiOp returns the results. If all tests are true, MultiOp executes t op (see item 2 below), otherwise
+// it executes f op (see item 3 below).
+// 2. A list of database operations called t op. Each operation in the list is either an insert, delete, or
+// lookup operation, and applies to a single database entry. Two different operations in the list may apply
+// to the same or different entries in the database. These operations are executed
+// if guard evaluates to
+// true.
+// 3. A list of database operations called f op. Like t op, but executed if guard evaluates to false.

+// 1. A list of tests called guard. Each test in guard checks a single entry in the database. It may check
+// for the absence or presence of a value, or compare with a given value. Two different tests in the guard
+// may apply to the same or different entries in the database. All tests in the guard are applied and
+// MultiOp returns the results. If all tests are true, MultiOp executes t op (see item 2 below), otherwise
+// it executes f op (see item 3 below).
+// 2. A list of database operations called t op. Each operation in the list is either an insert, delete, or
+// lookup operation, and applies to a single database entry. Two different operations in the list may apply
+// to the same or different entries in the database. These operations are executed
+// if guard evaluates to
+// true.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+Package spew implements a deep pretty printer for Go data structures to aid in
+debugging.
+
+A quick overview of the additional features spew provides over the built-in
+printing facilities for Go data types are as follows:
+
+	* Pointers are dereferenced and followed
+	* Circular data structures are detected and handled properly
+	* Custom Stringer/error interfaces are optionally invoked, including
+	  on unexported types
+	* Custom types which only implement the Stringer/error interfaces via
+	  a pointer receiver are optionally invoked when passing non-pointer
+	  variables
+	* Byte arrays and slices are dumped like the hexdump -C command which
+	  includes offsets, byte values in hex, and ASCII output (only when using
+	  Dump style)
+
+There are two different approaches spew allows for dumping Go data structures:
+
+	* Dump style which prints with newlines, customizable indentation,
+	  and additional debug information such as types and all pointer addresses
+	  used to indirect to the final value
+	* A custom Formatter interface that integrates cleanly with the standard fmt
+	  package and replaces %v, %+v, %#v, and %#+v to provide inline printing
+	  similar to the default %v while providing the additional functionality
+	  outlined above and passing unsupported format verbs such as %x and %q
+	  along to fmt
+
+Quick Start
+
+This section demonstrates how to quickly get started with spew.  See the
+sections below for further details on formatting and configuration options.
+
+To dump a variable with full newlines, indentation, type, and pointer
+information use Dump, Fdump, or Sdump:
+	spew.Dump(myVar1, myVar2, ...)
+	spew.Fdump(someWriter, myVar1, myVar2, ...)
+	str := spew.Sdump(myVar1, myVar2, ...)
+
+Alternatively, if you would prefer to use format strings with a compacted inline
+printing style, use the convenience wrappers Printf, Fprintf, etc with
+%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
+%#+v (adds types and pointer addresses):
+	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+	spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+Configuration Options
+
+Configuration of spew is handled by fields in the ConfigState type.  For
+convenience, all of the top-level functions use a global state available
+via the spew.Config global.
+
+It is also possible to create a ConfigState instance that provides methods
+equivalent to the top-level functions.  This allows concurrent configuration
+options.  See the ConfigState documentation for more details.
+
+The following configuration options are available:
+	* Indent
+		String to use for each indentation level for Dump functions.
+		It is a single space by default.  A popular alternative is "\t".
+
+	* MaxDepth
+		Maximum number of levels to descend into nested data structures.
+		There is no limit by default.
+
+	* DisableMethods
+		Disables invocation of error and Stringer interface methods.
+		Method invocation is enabled by default.
+
+	* DisablePointerMethods
+		Disables invocation of error and Stringer interface methods on types
+		which only accept pointer receivers from non-pointer variables.
+		Pointer method invocation is enabled by default.
+
+	* DisablePointerAddresses
+		DisablePointerAddresses specifies whether to disable the printing of
+		pointer addresses. This is useful when diffing data structures in tests.
+
+	* DisableCapacities
+		DisableCapacities specifies whether to disable the printing of
+		capacities for arrays, slices, maps and channels. This is useful when
+		diffing data structures in tests.
+
+	* ContinueOnMethod
+		Enables recursion into types after invoking error and Stringer interface
+		methods. Recursion after method invocation is disabled by default.
+
+	* SortKeys
+		Specifies map keys should be sorted before being printed. Use
+		this to have a more deterministic, diffable output.  Note that
+		only native types (bool, int, uint, floats, uintptr and string)
+		and types which implement error or Stringer interfaces are
+		supported with other types sorted according to the
+		reflect.Value.String() output which guarantees display
+		stability.  Natural map order is used by default.
+
+	* SpewKeys
+		Specifies that, as a last resort attempt, map keys should be
+		spewed to strings and sorted by those strings.  This is only
+		considered if SortKeys is true.
+
+Dump Usage
+
+Simply call spew.Dump with a list of variables you want to dump:
+
+	spew.Dump(myVar1, myVar2, ...)
+
+You may also call spew.Fdump if you would prefer to output to an arbitrary
+io.Writer.  For example, to dump to standard error:
+
+	spew.Fdump(os.Stderr, myVar1, myVar2, ...)
+
+A third option is to call spew.Sdump to get the formatted output as a string:
+
+	str := spew.Sdump(myVar1, myVar2, ...)
+
+Sample Dump Output
+
+See the Dump example for details on the setup of the types and variables being
+shown here.
+
+	(main.Foo) {
+	 unexportedField: (*main.Bar)(0xf84002e210)({
+	  flag: (main.Flag) flagTwo,
+	  data: (uintptr) <nil>
+	 }),
+	 ExportedField: (map[interface {}]interface {}) (len=1) {
+	  (string) (len=3) "one": (bool) true
+	 }
+	}
+
+Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
+command as shown.
+	([]uint8) (len=32 cap=32) {
+	 00000000  11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20  |............... |
+	 00000010  21 22 23 24 25 26 27 28  29 2a 2b 2c 2d 2e 2f 30  |!"#$%&'()*+,-./0|
+	 00000020  31 32                                             |12|
+	}
+
+Custom Formatter
+
+Spew provides a custom formatter that implements the fmt.Formatter interface
+so that it integrates cleanly with standard fmt package printing functions. The
+formatter is useful for inline printing of smaller data types similar to the
+standard %v format specifier.
+
+The custom formatter only responds to the %v (most compact), %+v (adds pointer
+addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
+combinations.  Any other verbs such as %x and %q will be sent to the the
+standard fmt package for formatting.  In addition, the custom formatter ignores
+the width and precision arguments (however they will still work on the format
+specifiers not handled by the custom formatter).
+
+Custom Formatter Usage
+
+The simplest way to make use of the spew custom formatter is to call one of the
+convenience functions such as spew.Printf, spew.Println, or spew.Printf.  The
+functions have syntax you are most likely already familiar with:
+
+	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+	spew.Println(myVar, myVar2)
+	spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+See the Index for the full list convenience functions.
+
+Sample Formatter Output
+
+Double pointer to a uint8:
+	  %v: <**>5
+	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
+	 %#v: (**uint8)5
+	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
+
+Pointer to circular struct with a uint8 field and a pointer to itself:
+	  %v: <*>{1 <*><shown>}
+	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
+	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
+	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
+
+See the Printf example for details on the setup of variables being shown
+here.
+
+Errors
+
+Since it is possible for custom Stringer/error interfaces to panic, spew
+detects them and handles them internally by printing the panic information
+inline with the output.  Since spew is intended to provide deep pretty printing
+capabilities on structures, it intentionally does not return any errors.

+
+The custom formatter only responds to the %v (most compact), %+v (adds pointer
+addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
+combinations.  Any other verbs such as %x and %q will be sent to the the
+standard fmt package for formatting.  In addition, the custom formatter ignores
+the width and precision arguments (however they will still work on the format
+specifiers not handled by the custom formatter).
+
+Typically this function shouldn't be called directly.  It is much easier to make
+use of the custom formatter by calling one of the convenience functions such as
+Printf, Println, or Fprintf.

+# go-bindata-assetfs
+
+Serve embedded files from [jteeuwen/go-bindata](https://github.com/jteeuwen/go-bindata) with `net/http`.
+
+[GoDoc](http://godoc.org/github.com/elazarl/go-bindata-assetfs)
+
+### Installation
+
+Install with
+
+    $ go get github.com/jteeuwen/go-bindata/...
+    $ go get github.com/elazarl/go-bindata-assetfs/...
+
+### Creating embedded data
+
+Usage is identical to [jteeuwen/go-bindata](https://github.com/jteeuwen/go-bindata) usage,
+instead of running `go-bindata` run `go-bindata-assetfs`.
+
+The tool will create a `bindata_assetfs.go` file, which contains the embedded data.
+
+A typical use case is
+
+    $ go-bindata-assetfs data/...
+
+### Using assetFS in your code
+
+The generated file provides an `assetFS()` function that returns a `http.Filesystem`
+wrapping the embedded files. What you usually want to do is:
+
+    http.Handle("/", http.FileServer(assetFS()))
+
+This would run an HTTP server serving the embedded files.
+
+## Without running binary tool
+
+You can always just run the `go-bindata` tool, and then
+
+use
+
+     import "github.com/elazarl/go-bindata-assetfs"
+     ...
+     http.Handle("/",
+        http.FileServer(
+        &assetfs.AssetFS{Asset: Asset, AssetDir: AssetDir, AssetInfo: AssetInfo, Prefix: "data"}))
+
+to serve files embedded from the `data` directory.

+
+How to use Swagger UI with go-restful
+=
+
+Get the Swagger UI sources (version 1.2 only)
+
+	git clone https://github.com/wordnik/swagger-ui.git
+	
+The project contains a "dist" folder.
+Its contents has all the Swagger UI files you need.
+
+The `index.html` has an `url` set to `http://petstore.swagger.wordnik.com/api/api-docs`.
+You need to change that to match your WebService JSON endpoint  e.g. `http://localhost:8080/apidocs.json`
+
+Now, you can install the Swagger WebService for serving the Swagger specification in JSON.
+
+	config := swagger.Config{
+		WebServices:    restful.RegisteredWebServices(),
+		ApiPath:        "/apidocs.json",
+		SwaggerPath:     "/apidocs/",
+		SwaggerFilePath: "/Users/emicklei/Projects/swagger-ui/dist"}
+	swagger.InstallSwaggerService(config)		
+	
+	
+Documenting Structs
+--
+
+Currently there are 2 ways to document your structs in the go-restful Swagger.
+
+###### By using struct tags
+- Use tag "description" to annotate a struct field with a description to show in the UI
+- Use tag "modelDescription" to annotate the struct itself with a description to show in the UI. The tag can be added in an field of the struct and in case that there are multiple definition, they will be appended with an empty line.
+
+###### By using the SwaggerDoc method
+Here is an example with an `Address` struct and the documentation for each of the fields. The `""` is a special entry for **documenting the struct itself**.
+
+	type Address struct {
+		Country  string `json:"country,omitempty"`
+		PostCode int    `json:"postcode,omitempty"`
+	}
+
+	func (Address) SwaggerDoc() map[string]string {
+		return map[string]string{
+			"":         "Address doc",
+			"country":  "Country doc",
+			"postcode": "PostCode doc",
+		}
+	}
+
+This example will generate a JSON like this
+
+	{
+		"Address": {
+			"id": "Address",
+			"description": "Address doc",
+			"properties": {
+				"country": {
+				"type": "string",
+				"description": "Country doc"
+				},
+				"postcode": {
+				"type": "integer",
+				"format": "int32",
+				"description": "PostCode doc"
+				}
+			}
+		}
+	}
+
+**Very Important Notes:**
+- `SwaggerDoc()` is using a **NON-Pointer** receiver (e.g. func (Address) and not func (*Address))
+- The returned map should use as key the name of the field as defined in the JSON parameter (e.g. `"postcode"` and not `"PostCode"`)
+
+Notes
+--
+- The Nickname of an Operation is automatically set by finding the name of the function. You can override it using RouteBuilder.Operation(..) 
+- The WebServices field of swagger.Config can be used to control which service you want to expose and document ; you can have multiple configs and therefore multiple endpoints.

+go-restful
+==========
+package for building REST-style Web Services using Google Go
+
+[![Build Status](https://travis-ci.org/emicklei/go-restful.png)](https://travis-ci.org/emicklei/go-restful)
+[![Go Report Card](https://goreportcard.com/badge/github.com/emicklei/go-restful)](https://goreportcard.com/report/github.com/emicklei/go-restful)
+[![GoDoc](https://godoc.org/github.com/emicklei/go-restful?status.svg)](https://godoc.org/github.com/emicklei/go-restful)
+
+- [Code examples](https://github.com/emicklei/go-restful/tree/master/examples)
+
+REST asks developers to use HTTP methods explicitly and in a way that's consistent with the protocol definition. This basic REST design principle establishes a one-to-one mapping between create, read, update, and delete (CRUD) operations and HTTP methods. According to this mapping:
+
+- GET = Retrieve a representation of a resource
+- POST = Create if you are sending content to the server to create a subordinate of the specified resource collection, using some server-side algorithm.
+- PUT = Create if you are sending the full content of the specified resource (URI).
+- PUT = Update if you are updating the full content of the specified resource.
+- DELETE = Delete if you are requesting the server to delete the resource
+- PATCH = Update partial content of a resource
+- OPTIONS = Get information about the communication options for the request URI
+    
+### Example
+
+```Go
+ws := new(restful.WebService)
+ws.
+	Path("/users").
+	Consumes(restful.MIME_XML, restful.MIME_JSON).
+	Produces(restful.MIME_JSON, restful.MIME_XML)
+
+ws.Route(ws.GET("/{user-id}").To(u.findUser).
+	Doc("get a user").
+	Param(ws.PathParameter("user-id", "identifier of the user").DataType("string")).
+	Writes(User{}))		
+...
+	
+func (u UserResource) findUser(request *restful.Request, response *restful.Response) {
+	id := request.PathParameter("user-id")
+	...
+}
+```
+	
+[Full API of a UserResource](https://github.com/emicklei/go-restful/tree/master/examples/restful-user-resource.go) 
+		
+### Features
+
+- Routes for request &#8594; function mapping with path parameter (e.g. {id}) support
+- Configurable router:
+	- (default) Fast routing algorithm that allows static elements, regular expressions and dynamic parameters in the URL path (e.g. /meetings/{id} or /static/{subpath:*}
+	- Routing algorithm after [JSR311](http://jsr311.java.net/nonav/releases/1.1/spec/spec.html) that is implemented using (but does **not** accept) regular expressions
+- Request API for reading structs from JSON/XML and accesing parameters (path,query,header)
+- Response API for writing structs to JSON/XML and setting headers
+- Customizable encoding using EntityReaderWriter registration
+- Filters for intercepting the request &#8594; response flow on Service or Route level
+- Request-scoped variables using attributes
+- Containers for WebServices on different HTTP endpoints
+- Content encoding (gzip,deflate) of request and response payloads
+- Automatic responses on OPTIONS (using a filter)
+- Automatic CORS request handling (using a filter)
+- API declaration for Swagger UI ([go-restful-openapi](https://github.com/emicklei/go-restful-openapi), see [go-restful-swagger12](https://github.com/emicklei/go-restful-swagger12))
+- Panic recovery to produce HTTP 500, customizable using RecoverHandler(...)
+- Route errors produce HTTP 404/405/406/415 errors, customizable using ServiceErrorHandler(...)
+- Configurable (trace) logging
+- Customizable gzip/deflate readers and writers using CompressorProvider registration
+
+## How to customize
+There are several hooks to customize the behavior of the go-restful package.
+
+- Router algorithm
+- Panic recovery
+- JSON decoder
+- Trace logging
+- Compression
+- Encoders for other serializers
+- Use [jsoniter](https://github.com/json-iterator/go) by build this package using a tag, e.g. `go build -tags=jsoniter .`
+
+TODO: write examples of these.
+

+/*
+Package restful , a lean package for creating REST-style WebServices without magic.
+
+WebServices and Routes
+
+A WebService has a collection of Route objects that dispatch incoming Http Requests to a function calls.
+Typically, a WebService has a root path (e.g. /users) and defines common MIME types for its routes.
+WebServices must be added to a container (see below) in order to handler Http requests from a server.
+
+A Route is defined by a HTTP method, an URL path and (optionally) the MIME types it consumes (Content-Type) and produces (Accept).
+This package has the logic to find the best matching Route and if found, call its Function.
+
+	ws := new(restful.WebService)
+	ws.
+		Path("/users").
+		Consumes(restful.MIME_JSON, restful.MIME_XML).
+		Produces(restful.MIME_JSON, restful.MIME_XML)
+
+	ws.Route(ws.GET("/{user-id}").To(u.findUser))  // u is a UserResource
+
+	...
+
+	// GET http://localhost:8080/users/1
+	func (u UserResource) findUser(request *restful.Request, response *restful.Response) {
+		id := request.PathParameter("user-id")
+		...
+	}
+
+The (*Request, *Response) arguments provide functions for reading information from the request and writing information back to the response.
+
+See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-user-resource.go with a full implementation.
+
+Regular expression matching Routes
+
+A Route parameter can be specified using the format "uri/{var[:regexp]}" or the special version "uri/{var:*}" for matching the tail of the path.
+For example, /persons/{name:[A-Z][A-Z]} can be used to restrict values for the parameter "name" to only contain capital alphabetic characters.
+Regular expressions must use the standard Go syntax as described in the regexp package. (https://code.google.com/p/re2/wiki/Syntax)
+This feature requires the use of a CurlyRouter.
+
+Containers
+
+A Container holds a collection of WebServices, Filters and a http.ServeMux for multiplexing http requests.
+Using the statements "restful.Add(...) and restful.Filter(...)" will register WebServices and Filters to the Default Container.
+The Default container of go-restful uses the http.DefaultServeMux.
+You can create your own Container and create a new http.Server for that particular container.
+
+	container := restful.NewContainer()
+	server := &http.Server{Addr: ":8081", Handler: container}
+
+Filters
+
+A filter dynamically intercepts requests and responses to transform or use the information contained in the requests or responses.
+You can use filters to perform generic logging, measurement, authentication, redirect, set response headers etc.
+In the restful package there are three hooks into the request,response flow where filters can be added.
+Each filter must define a FilterFunction:
+
+	func (req *restful.Request, resp *restful.Response, chain *restful.FilterChain)
+
+Use the following statement to pass the request,response pair to the next filter or RouteFunction
+
+	chain.ProcessFilter(req, resp)
+
+Container Filters
+
+These are processed before any registered WebService.
+
+	// install a (global) filter for the default container (processed before any webservice)
+	restful.Filter(globalLogging)
+
+WebService Filters
+
+These are processed before any Route of a WebService.
+
+	// install a webservice filter (processed before any route)
+	ws.Filter(webserviceLogging).Filter(measureTime)
+
+
+Route Filters
+
+These are processed before calling the function associated with the Route.
+
+	// install 2 chained route filters (processed before calling findUser)
+	ws.Route(ws.GET("/{user-id}").Filter(routeLogging).Filter(NewCountFilter().routeCounter).To(findUser))
+
+See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-filters.go with full implementations.
+
+Response Encoding
+
+Two encodings are supported: gzip and deflate. To enable this for all responses:
+
+	restful.DefaultContainer.EnableContentEncoding(true)
+
+If a Http request includes the Accept-Encoding header then the response content will be compressed using the specified encoding.
+Alternatively, you can create a Filter that performs the encoding and install it per WebService or Route.
+
+See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-encoding-filter.go
+
+OPTIONS support
+
+By installing a pre-defined container filter, your Webservice(s) can respond to the OPTIONS Http request.
+
+	Filter(OPTIONSFilter())
+
+CORS
+
+By installing the filter of a CrossOriginResourceSharing (CORS), your WebService(s) can handle CORS requests.
+
+	cors := CrossOriginResourceSharing{ExposeHeaders: []string{"X-My-Header"}, CookiesAllowed: false, Container: DefaultContainer}
+	Filter(cors.Filter)
+
+Error Handling
+
+Unexpected things happen. If a request cannot be processed because of a failure, your service needs to tell via the response what happened and why.
+For this reason HTTP status codes exist and it is important to use the correct code in every exceptional situation.
+
+	400: Bad Request
+
+If path or query parameters are not valid (content or type) then use http.StatusBadRequest.
+
+	404: Not Found
+
+Despite a valid URI, the resource requested may not be available
+
+	500: Internal Server Error
+
+If the application logic could not process the request (or write the response) then use http.StatusInternalServerError.
+
+	405: Method Not Allowed
+
+The request has a valid URL but the method (GET,PUT,POST,...) is not allowed.
+
+	406: Not Acceptable
+
+The request does not have or has an unknown Accept Header set for this operation.
+
+	415: Unsupported Media Type
+
+The request does not have or has an unknown Content-Type Header set for this operation.
+
+ServiceError
+
+In addition to setting the correct (error) Http status code, you can choose to write a ServiceError message on the response.
+
+Performance options
+
+This package has several options that affect the performance of your service. It is important to understand them and how you can change it.
+
+	restful.DefaultContainer.DoNotRecover(false)
+
+DoNotRecover controls whether panics will be caught to return HTTP 500.
+If set to false, the container will recover from panics.
+Default value is true
+
+	restful.SetCompressorProvider(NewBoundedCachedCompressors(20, 20))
+
+If content encoding is enabled then the default strategy for getting new gzip/zlib writers and readers is to use a sync.Pool.
+Because writers are expensive structures, performance is even more improved when using a preloaded cache. You can also inject your own implementation.
+
+Trouble shooting
+
+This package has the means to produce detail logging of the complete Http request matching process and filter invocation.
+Enabling this feature requires you to set an implementation of restful.StdLogger (e.g. log.Logger) instance such as:
+
+	restful.TraceLogger(log.New(os.Stdout, "[restful] ", log.LstdFlags|log.Lshortfile))
+
+Logging
+
+The restful.SetLogger() method allows you to override the logger used by the package. By default restful
+uses the standard library `log` package and logs to stdout. Different logging packages are supported as
+long as they conform to `StdLogger` interface defined in the `log` sub-package, writing an adapter for your
+preferred package is simple.

+## JSON-Patch
+
+Provides the ability to modify and test a JSON according to a
+[RFC6902 JSON patch](http://tools.ietf.org/html/rfc6902) and [RFC7396 JSON Merge Patch](https://tools.ietf.org/html/rfc7396).
+
+*Version*: **1.0**
+
+[![GoDoc](https://godoc.org/github.com/evanphx/json-patch?status.svg)](http://godoc.org/github.com/evanphx/json-patch)
+
+[![Build Status](https://travis-ci.org/evanphx/json-patch.svg?branch=master)](https://travis-ci.org/evanphx/json-patch)
+
+### API Usage
+
+* Given a `[]byte`, obtain a Patch object
+
+  `obj, err := jsonpatch.DecodePatch(patch)`
+
+* Apply the patch and get a new document back
+
+  `out, err := obj.Apply(doc)`
+
+* Create a JSON Merge Patch document based on two json documents (a to b):
+
+  `mergeDoc, err := jsonpatch.CreateMergePatch(a, b)`
+ 
+* Bonus API: compare documents for structural equality
+
+  `jsonpatch.Equal(doca, docb)`
+

+# YAML marshaling and unmarshaling support for Go
+
+[![Build Status](https://travis-ci.org/ghodss/yaml.svg)](https://travis-ci.org/ghodss/yaml)
+
+## Introduction
+
+A wrapper around [go-yaml](https://github.com/go-yaml/yaml) designed to enable a better way of handling YAML when marshaling to and from structs.
+
+In short, this library first converts YAML to JSON using go-yaml and then uses `json.Marshal` and `json.Unmarshal` to convert to or from the struct. This means that it effectively reuses the JSON struct tags as well as the custom JSON methods `MarshalJSON` and `UnmarshalJSON` unlike go-yaml. For a detailed overview of the rationale behind this method, [see this blog post](http://ghodss.com/2014/the-right-way-to-handle-yaml-in-golang/).
+
+## Compatibility
+
+This package uses [go-yaml](https://github.com/go-yaml/yaml) and therefore supports [everything go-yaml supports](https://github.com/go-yaml/yaml#compatibility).
+
+## Caveats
+
+**Caveat #1:** When using `yaml.Marshal` and `yaml.Unmarshal`, binary data should NOT be preceded with the `!!binary` YAML tag. If you do, go-yaml will convert the binary data from base64 to native binary data, which is not compatible with JSON. You can still use binary in your YAML files though - just store them without the `!!binary` tag and decode the base64 in your code (e.g. in the custom JSON methods `MarshalJSON` and `UnmarshalJSON`). This also has the benefit that your YAML and your JSON binary data will be decoded exactly the same way. As an example:
+
+```
+BAD:
+	exampleKey: !!binary gIGC
+
+GOOD:
+	exampleKey: gIGC
+... and decode the base64 data in your code.
+```
+
+**Caveat #2:** When using `YAMLToJSON` directly, maps with keys that are maps will result in an error since this is not supported by JSON. This error will occur in `Unmarshal` as well since you can't unmarshal map keys anyways since struct fields can't be keys.
+
+## Installation and usage
+
+To install, run:
+
+```
+$ go get github.com/ghodss/yaml
+```
+
+And import using:
+
+```
+import "github.com/ghodss/yaml"
+```
+
+Usage is very similar to the JSON library:
+
+```go
+package main
+
+import (
+	"fmt"
+
+	"github.com/ghodss/yaml"
+)
+
+type Person struct {
+	Name string `json:"name"` // Affects YAML field names too.
+	Age  int    `json:"age"`
+}
+
+func main() {
+	// Marshal a Person struct to YAML.
+	p := Person{"John", 30}
+	y, err := yaml.Marshal(p)
+	if err != nil {
+		fmt.Printf("err: %v\n", err)
+		return
+	}
+	fmt.Println(string(y))
+	/* Output:
+	age: 30
+	name: John
+	*/
+
+	// Unmarshal the YAML back into a Person struct.
+	var p2 Person
+	err = yaml.Unmarshal(y, &p2)
+	if err != nil {
+		fmt.Printf("err: %v\n", err)
+		return
+	}
+	fmt.Println(p2)
+	/* Output:
+	{John 30}
+	*/
+}
+```
+
+`yaml.YAMLToJSON` and `yaml.JSONToYAML` methods are also available:
+
+```go
+package main
+
+import (
+	"fmt"
+
+	"github.com/ghodss/yaml"
+)
+
+func main() {
+	j := []byte(`{"name": "John", "age": 30}`)
+	y, err := yaml.JSONToYAML(j)
+	if err != nil {
+		fmt.Printf("err: %v\n", err)
+		return
+	}
+	fmt.Println(string(y))
+	/* Output:
+	name: John
+	age: 30
+	*/
+	j2, err := yaml.YAMLToJSON(y)
+	if err != nil {
+		fmt.Printf("err: %v\n", err)
+		return
+	}
+	fmt.Println(string(j2))
+	/* Output:
+	{"age":30,"name":"John"}
+	*/
+}
+```

+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at ivan+abuse@flanders.co.nz. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at ivan+abuse@flanders.co.nz. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at ivan+abuse@flanders.co.nz. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+
+      "Source" form shall mean the preferred form for making modifications,

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+// Parameter a unique parameter is defined by a combination of a [name](#parameterName) and [location](#parameterIn).
+//
+// There are five possible parameter types.
+// * Path - Used together with [Path Templating](#pathTemplating), where the parameter value is actually part of the operation's URL. This does not include the host or base path of the API. For example, in `/items/{itemId}`, the path parameter is `itemId`.
+// * Query - Parameters that are appended to the URL. For example, in `/items?id=###`, the query parameter is `id`.
+// * Header - Custom headers that are expected as part of the request.
+// * Body - The payload that's appended to the HTTP request. Since there can only be one payload, there can only be *one* body parameter. The name of the body parameter has no effect on the parameter itself and is used for documentation purposes only. Since Form parameters are also in the payload, body and form parameters cannot exist together for the same operation.
+// * Form - Used to describe the payload of an HTTP request when either `application/x-www-form-urlencoded` or `multipart/form-data` are used as the content type of the request (in Swagger's definition, the [`consumes`](#operationConsumes) property of an operation). This is the only parameter type that can be used to send files, thus supporting the `file` type. Since form parameters are sent in the payload, they cannot be declared together with a body parameter for the same operation. Form parameters have a different format based on the content-type used (for further details, consult http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4):
+//   * `application/x-www-form-urlencoded` - Similar to the format of Query parameters but as a payload. For example, `foo=1&bar=swagger` - both `foo` and `bar` are form parameters. This is normally used for simple parameters that are being transferred.
+//   * `multipart/form-data` - each parameter takes a section in the payload with an internal header. For example, for the header `Content-Disposition: form-data; name="submit-name"` the name of the parameter is `submit-name`. This type of form parameters is more commonly used for file transfers.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at ivan+abuse@flanders.co.nz. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but

+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+Package gogoproto provides extensions for protocol buffers to achieve:
+
+  - fast marshalling and unmarshalling.
+  - peace of mind by optionally generating test and benchmark code.
+  - more canonical Go structures.
+  - less typing by optionally generating extra helper code.
+  - goprotobuf compatibility
+
+More Canonical Go Structures
+
+A lot of time working with a goprotobuf struct will lead you to a place where you create another struct that is easier to work with and then have a function to copy the values between the two structs.
+You might also find that basic structs that started their life as part of an API need to be sent over the wire. With gob, you could just send it. With goprotobuf, you need to make a parallel struct.
+Gogoprotobuf tries to fix these problems with the nullable, embed, customtype and customname field extensions.
+
+  - nullable, if false, a field is generated without a pointer (see warning below).
+  - embed, if true, the field is generated as an embedded field.
+  - customtype, It works with the Marshal and Unmarshal methods, to allow you to have your own types in your struct, but marshal to bytes. For example, custom.Uuid or custom.Fixed128
+  - customname (beta), Changes the generated fieldname. This is especially useful when generated methods conflict with fieldnames.
+  - casttype (beta), Changes the generated fieldtype.  All generated code assumes that this type is castable to the protocol buffer field type.  It does not work for structs or enums.
+  - castkey (beta), Changes the generated fieldtype for a map key.  All generated code assumes that this type is castable to the protocol buffer field type.  Only supported on maps.
+  - castvalue (beta), Changes the generated fieldtype for a map value.  All generated code assumes that this type is castable to the protocol buffer field type.  Only supported on maps.
+
+Warning about nullable: According to the Protocol Buffer specification, you should be able to tell whether a field is set or unset. With the option nullable=false this feature is lost, since your non-nullable fields will always be set. It can be seen as a layer on top of Protocol Buffers, where before and after marshalling all non-nullable fields are set and they cannot be unset.
+
+Let us look at:
+
+	github.com/gogo/protobuf/test/example/example.proto
+
+for a quicker overview.
+
+The following message:
+
+  package test;
+
+  import "github.com/gogo/protobuf/gogoproto/gogo.proto";
+
+	message A {
+		optional string Description = 1 [(gogoproto.nullable) = false];
+		optional int64 Number = 2 [(gogoproto.nullable) = false];
+		optional bytes Id = 3 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uuid", (gogoproto.nullable) = false];
+	}
+
+Will generate a go struct which looks a lot like this:
+
+	type A struct {
+		Description string
+		Number      int64
+		Id          github_com_gogo_protobuf_test_custom.Uuid
+	}
+
+You will see there are no pointers, since all fields are non-nullable.
+You will also see a custom type which marshals to a string.
+Be warned it is your responsibility to test your custom types thoroughly.
+You should think of every possible empty and nil case for your marshaling, unmarshaling and size methods.
+
+Next we will embed the message A in message B.
+
+	message B {
+		optional A A = 1 [(gogoproto.nullable) = false, (gogoproto.embed) = true];
+		repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false];
+	}
+
+See below that A is embedded in B.
+
+	type B struct {
+		A
+		G []github_com_gogo_protobuf_test_custom.Uint128
+	}
+
+Also see the repeated custom type.
+
+	type Uint128 [2]uint64
+
+Next we will create a custom name for one of our fields.
+
+	message C {
+		optional int64 size = 1 [(gogoproto.customname) = "MySize"];
+	}
+
+See below that the field's name is MySize and not Size.
+
+	type C struct {
+		MySize		*int64
+	}
+
+The is useful when having a protocol buffer message with a field name which conflicts with a generated method.
+As an example, having a field name size and using the sizer plugin to generate a Size method will cause a go compiler error.
+Using customname you can fix this error without changing the field name.
+This is typically useful when working with a protocol buffer that was designed before these methods and/or the go language were avialable.
+
+Gogoprotobuf also has some more subtle changes, these could be changed back:
+
+  - the generated package name for imports do not have the extra /filename.pb,
+  but are actually the imports specified in the .proto file.
+
+Gogoprotobuf also has lost some features which should be brought back with time:
+
+  - Marshalling and unmarshalling with reflect and without the unsafe package,
+  this requires work in pointer_reflect.go
+
+Why does nullable break protocol buffer specifications:
+
+The protocol buffer specification states, somewhere, that you should be able to tell whether a
+field is set or unset.  With the option nullable=false this feature is lost,
+since your non-nullable fields will always be set.  It can be seen as a layer on top of
+protocol buffers, where before and after marshalling all non-nullable fields are set
+and they cannot be unset.
+
+Goprotobuf Compatibility:
+
+Gogoprotobuf is compatible with Goprotobuf, because it is compatible with protocol buffers.
+Gogoprotobuf generates the same code as goprotobuf if no extensions are used.
+The enumprefix, getters and stringer extensions can be used to remove some of the unnecessary code generated by goprotobuf:
+
+  - gogoproto_import, if false, the generated code imports github.com/golang/protobuf/proto instead of github.com/gogo/protobuf/proto.
+  - goproto_enum_prefix, if false, generates the enum constant names without the messagetype prefix
+  - goproto_enum_stringer (experimental), if false, the enum is generated without the default string method, this is useful for rather using enum_stringer, or allowing you to write your own string method.
+  - goproto_getters, if false, the message is generated without get methods, this is useful when you would rather want to use face
+  - goproto_stringer, if false, the message is generated without the default string method, this is useful for rather using stringer, or allowing you to write your own string method.
+  - goproto_extensions_map (beta), if false, the extensions field is generated as type []byte instead of type map[int32]proto.Extension
+  - goproto_unrecognized (beta), if false, XXX_unrecognized field is not generated. This is useful in conjunction with gogoproto.nullable=false, to generate structures completely devoid of pointers and reduce GC pressure at the cost of losing information about unrecognized fields.
+  - goproto_registration (beta), if true, the generated files will register all messages and types against both gogo/protobuf and golang/protobuf. This is necessary when using third-party packages which read registrations from golang/protobuf (such as the grpc-gateway).
+
+Less Typing and Peace of Mind is explained in their specific plugin folders godoc:
+
+	- github.com/gogo/protobuf/plugin/<extension_name>
+
+If you do not use any of these extension the code that is generated
+will be the same as if goprotobuf has generated it.
+
+The most complete way to see examples is to look at
+
+	github.com/gogo/protobuf/test/thetest.proto
+
+Gogoprototest is a seperate project,
+because we want to keep gogoprotobuf independant of goprotobuf,
+but we still want to test it thoroughly.

+Equal returns true iff protocol buffers a and b are equal.
+The arguments must both be pointers to protocol buffer structs.
+
+Equality is defined in this way:
+  - Two messages are equal iff they are the same type,
+    corresponding fields are equal, unknown field sets
+    are equal, and extensions sets are equal.
+  - Two set scalar fields are equal iff their values are equal.
+    If the fields are of a floating-point type, remember that
+    NaN != x for all x, including NaN. If the message is defined
+    in a proto3 .proto file, fields are not "set"; specifically,
+    zero length proto3 "bytes" fields are equal (nil == {}).
+  - Two repeated fields are equal iff their lengths are the same,
+    and their corresponding elements are equal. Note a "bytes" field,
+    although represented by []byte, is not a repeated field and the
+    rule for the scalar fields described above applies.
+  - Two unset fields are equal.
+  - Two unknown field sets are equal if their current
+    encoded state is equal.
+  - Two extension sets are equal iff they have corresponding
+    elements that are pairwise equal.
+  - Two map fields are equal iff their lengths are the same,
+    and they contain the same set of elements. Zero-length map
+    fields are equal.
+  - Every other combination of things are not equal.
+
+The return value is undefined if a and b are not protocol buffers.

+Package proto converts data structures to and from the wire format of
+protocol buffers.  It works in concert with the Go source code generated
+for .proto files by the protocol compiler.
+
+A summary of the properties of the protocol buffer interface
+for a protocol buffer variable v:
+
+  - Names are turned from camel_case to CamelCase for export.
+  - There are no methods on v to set fields; just treat
+	them as structure fields.
+  - There are getters that return a field's value if set,
+	and return the field's default value if unset.
+	The getters work even if the receiver is a nil message.
+  - The zero value for a struct is its correct initialization state.
+	All desired fields must be set before marshaling.
+  - A Reset() method will restore a protobuf struct to its zero state.
+  - Non-repeated fields are pointers to the values; nil means unset.
+	That is, optional or required field int32 f becomes F *int32.
+  - Repeated fields are slices.
+  - Helper functions are available to aid the setting of fields.
+	msg.Foo = proto.String("hello") // set field
+  - Constants are defined to hold the default values of all fields that
+	have them.  They have the form Default_StructName_FieldName.
+	Because the getter methods handle defaulted values,
+	direct use of these constants should be rare.
+  - Enums are given type names and maps from names to values.
+	Enum values are prefixed by the enclosing message's name, or by the
+	enum's type name if it is a top-level enum. Enum types have a String
+	method, and a Enum method to assist in message construction.
+  - Nested messages, groups and enums have type names prefixed with the name of
+	the surrounding message type.
+  - Extensions are given descriptor names that start with E_,
+	followed by an underscore-delimited list of the nested messages
+	that contain it (if any) followed by the CamelCased name of the
+	extension field itself.  HasExtension, ClearExtension, GetExtension
+	and SetExtension are functions for manipulating extensions.
+  - Oneof field sets are given a single field in their message,
+	with distinguished wrapper types for each possible field value.
+  - Marshal and Unmarshal are functions to encode and decode the wire format.
+
+When the .proto file specifies `syntax="proto3"`, there are some differences:
+
+  - Non-repeated fields of non-message type are values instead of pointers.
+  - Enum types do not get an Enum method.
+
+The simplest way to describe this is to see an example.
+Given file test.proto, containing
+
+	package example;
+
+	enum FOO { X = 17; }
+
+	message Test {
+	  required string label = 1;
+	  optional int32 type = 2 [default=77];
+	  repeated int64 reps = 3;
+	  optional group OptionalGroup = 4 {
+	    required string RequiredField = 5;
+	  }
+	  oneof union {
+	    int32 number = 6;
+	    string name = 7;

+	// tools.
+	//
+	// For example, say we have a file like:
+	//   message Foo {
+	//     optional string foo = 1;
+	//   }
+	// Let's look at just the field definition:
+	//   optional string foo = 1;
+	//   ^       ^^     ^^  ^  ^^^
+	//   a       bc     de  f  ghi
+	// We have the following locations:
+	//   span   path               represents
+	//   [a,i)  [ 4, 0, 2, 0 ]     The whole field definition.
+	//   [a,b)  [ 4, 0, 2, 0, 4 ]  The label (optional).
+	//   [c,d)  [ 4, 0, 2, 0, 5 ]  The type (string).
+	//   [e,f)  [ 4, 0, 2, 0, 1 ]  The name (foo).
+	//   [g,h)  [ 4, 0, 2, 0, 3 ]  The number (1).
+	//
+	// Notes:
+	// - A location may refer to a repeated field itself (i.e. not to any
+	//   particular index within it).  This is used whenever a set of elements are
+	//   logically enclosed in a single code segment.  For example, an entire
+	//   extend block (possibly containing multiple extension definitions) will
+	//   have an outer location whose path refers to the "extensions" repeated
+	//   field without an index.
+	// - Multiple locations may have the same path.  This happens when a single
+	//   logical declaration is spread out across multiple places.  The most
+	//   obvious example is the "extend" block again -- there may be multiple
+	//   extend blocks in the same scope, each of which will have the same path.
+	// - A location's span is not always a subset of its parent's span.  For
+	//   example, the "extendee" of an extension declaration appears at the
+	//   beginning of the "extend" block and is shared by all extensions within
+	//   the block.
+	// - Just because a location's span is a subset of some other location's span
+	//   does not mean that it is a descendent.  For example, a "group" defines
+	//   both a type and a field in a single declaration.  Thus, the locations
+	//   corresponding to the type and field and their components will overlap.
+	// - Code which tries to interpret locations should probably be designed to
+	//   ignore those that it doesn't understand, as more types of locations could
+	//   be recorded in the future.

+====
+
+Leveled execution logs for Go.
+
+This is an efficient pure Go implementation of leveled logs in the
+manner of the open source C++ package
+	https://github.com/google/glog
+
+By binding methods to booleans it is possible to use the log package
+without paying the expense of evaluating the arguments to the log.
+Through the -vmodule flag, the package also provides fine-grained
+control over logging at the file level.
+
+The comment from glog.go introduces the ideas:
+
+	Package glog implements logging analogous to the Google-internal
+	C++ INFO/ERROR/V setup.  It provides functions Info, Warning,
+	Error, Fatal, plus formatting variants such as Infof. It
+	also provides V-style logging controlled by the -v and
+	-vmodule=file=2 flags.
+	
+	Basic examples:
+	
+		glog.Info("Prepare to repel boarders")
+	
+		glog.Fatalf("Initialization failed: %s", err)
+	
+	See the documentation for the V function for an explanation
+	of these examples:
+	
+		if glog.V(2) {
+			glog.Info("Starting transaction...")
+		}
+	
+		glog.V(2).Infoln("Processed", nItems, "elements")
+
+
+The repository contains an open source version of the log package
+used inside Google. The master copy of the source lives inside
+Google, not here. The code in this repo is for export only and is not itself
+under development. Feature requests will be ignored.
+
+Send bug reports to golang-nuts@googlegroups.com.

+// As a result, flag.Parse must be called before any logging is done.
+//
+//	-logtostderr=false
+//		Logs are written to standard error instead of to files.
+//	-alsologtostderr=false
+//		Logs are written to standard error as well as to files.
+//	-stderrthreshold=ERROR
+//		Log events at or above this severity are logged to standard
+//		error as well as to files.
+//	-log_dir=""
+//		Log files will be written to this directory instead of the
+//		default temporary directory.
+//
+//	Other flags provide aids to debugging.
+//
+//	-log_backtrace_at=""
+//		When set to a file and line number holding a logging statement,

+Equal returns true iff protocol buffers a and b are equal.
+The arguments must both be pointers to protocol buffer structs.

+Equality is defined in this way:
+  - Two messages are equal iff they are the same type,
+    corresponding fields are equal, unknown field sets
+    are equal, and extensions sets are equal.
+  - Two set scalar fields are equal iff their values are equal.
+    If the fields are of a floating-point type, remember that
+    NaN != x for all x, including NaN. If the message is defined
+    in a proto3 .proto file, fields are not "set"; specifically,
+    zero length proto3 "bytes" fields are equal (nil == {}).
+  - Two repeated fields are equal iff their lengths are the same,
+    and their corresponding elements are equal. Note a "bytes" field,
+    although represented by []byte, is not a repeated field and the
+    rule for the scalar fields described above applies.
+  - Two unset fields are equal.
+  - Two unknown field sets are equal if their current
+    encoded state is equal.
+  - Two extension sets are equal iff they have corresponding
+    elements that are pairwise equal.
+  - Two map fields are equal iff their lengths are the same,
+    and they contain the same set of elements. Zero-length map
+    fields are equal.
+  - Every other combination of things are not equal.

+Package proto converts data structures to and from the wire format of
+protocol buffers.  It works in concert with the Go source code generated
+for .proto files by the protocol compiler.
+
+A summary of the properties of the protocol buffer interface
+for a protocol buffer variable v:
+
+  - Names are turned from camel_case to CamelCase for export.
+  - There are no methods on v to set fields; just treat
+	them as structure fields.
+  - There are getters that return a field's value if set,
+	and return the field's default value if unset.
+	The getters work even if the receiver is a nil message.
+  - The zero value for a struct is its correct initialization state.
+	All desired fields must be set before marshaling.
+  - A Reset() method will restore a protobuf struct to its zero state.
+  - Non-repeated fields are pointers to the values; nil means unset.
+	That is, optional or required field int32 f becomes F *int32.
+  - Repeated fields are slices.
+  - Helper functions are available to aid the setting of fields.
+	msg.Foo = proto.String("hello") // set field
+  - Constants are defined to hold the default values of all fields that
+	have them.  They have the form Default_StructName_FieldName.
+	Because the getter methods handle defaulted values,
+	direct use of these constants should be rare.
+  - Enums are given type names and maps from names to values.
+	Enum values are prefixed by the enclosing message's name, or by the
+	enum's type name if it is a top-level enum. Enum types have a String
+	method, and a Enum method to assist in message construction.
+  - Nested messages, groups and enums have type names prefixed with the name of
+	the surrounding message type.
+  - Extensions are given descriptor names that start with E_,
+	followed by an underscore-delimited list of the nested messages
+	that contain it (if any) followed by the CamelCased name of the
+	extension field itself.  HasExtension, ClearExtension, GetExtension
+	and SetExtension are functions for manipulating extensions.
+  - Oneof field sets are given a single field in their message,
+	with distinguished wrapper types for each possible field value.
+  - Marshal and Unmarshal are functions to encode and decode the wire format.
+
+When the .proto file specifies `syntax="proto3"`, there are some differences:
+
+  - Non-repeated fields of non-message type are values instead of pointers.
+  - Enum types do not get an Enum method.
+
+The simplest way to describe this is to see an example.
+Given file test.proto, containing
+
+	package example;
+
+	enum FOO { X = 17; }
+
+	message Test {
+	  required string label = 1;
+	  optional int32 type = 2 [default=77];
+	  repeated int64 reps = 3;
+	  optional group OptionalGroup = 4 {
+	    required string RequiredField = 5;

+//     Any any = Any.pack(foo);
+//     ...
+//     if (any.is(Foo.class)) {

+// The pack methods provided by protobuf library will by default use

+// methods only use the fully qualified type name after the last '/'
+// in the type URL, for example "foo.bar.com/x/y.z" will yield type
+// name "y.z".
+//
+//
+// JSON
+// ====
+// The JSON representation of an `Any` value uses the regular
+// representation of the deserialized, embedded message, with an
+// additional field `@type` which contains the type URL. Example:
+//
+//     package google.profile;
+//     message Person {
+//       string first_name = 1;
+//       string last_name = 2;
+//     }
+//
+//     {
+//       "@type": "type.googleapis.com/google.profile.Person",
+//       "firstName": <string>,
+//       "lastName": <string>
+//     }
+//
+// If the embedded message type is well-known and has a custom JSON
+// representation, that representation will be embedded adding a field
+// `value` which holds the custom JSON in addition to the `@type`
+// field. Example (for message [google.protobuf.Duration][]):
+//
+//     {
+//       "@type": "type.googleapis.com/google.protobuf.Duration",
+//       "value": "1.212s"
+//     }
+//
+type Any struct {
+	// A URL/resource name whose content describes the type of the
+	// serialized protocol buffer message.
+	//
+	// For URLs which use the scheme `http`, `https`, or no scheme, the
+	// following restrictions and interpretations apply:
+	//
+	// * If no scheme is provided, `https` is assumed.
+	// * The last segment of the URL's path must represent the fully
+	//   qualified name of the type (as in `path/google.protobuf.Duration`).
+	//   The name should be in a canonical form (e.g., leading "." is
+	//   not accepted).
+	// * An HTTP GET on the URL must yield a [google.protobuf.Type][]
+	//   value in binary format, or produce an error.
+	// * Applications are allowed to cache lookup results based on the
+	//   URL, or have them precompiled into a binary to avoid any
+	//   lookup. Therefore, binary compatibility needs to be preserved
+	//   on changes to types. (Use versioned type names to manage
+	//   breaking changes.)
+	//
+	// Schemes other than `http`, `https` (or the empty scheme) might be
+	// used with implementation specific semantics.

+// `Any` contains an arbitrary serialized protocol buffer message along with a
+// URL that describes the type of the serialized message.
+//
+// Protobuf library provides support to pack/unpack Any values in the form
+// of utility functions or additional generated methods of the Any type.
+//
+// Example 1: Pack and unpack a message in C++.
+//
+//     Foo foo = ...;
+//     Any any;
+//     any.PackFrom(foo);
+//     ...
+//     if (any.UnpackTo(&foo)) {
+//       ...
+//     }
+//
+// Example 2: Pack and unpack a message in Java.
+//
+//     Foo foo = ...;
+//     Any any = Any.pack(foo);
+//     ...
+//     if (any.is(Foo.class)) {
+//       foo = any.unpack(Foo.class);
+//     }
+//
+//  Example 3: Pack and unpack a message in Python.
+//
+//     foo = Foo(...)
+//     any = Any()
+//     any.Pack(foo)
+//     ...
+//     if any.Is(Foo.DESCRIPTOR):
+//       any.Unpack(foo)
+//       ...
+//
+//  Example 4: Pack and unpack a message in Go
+//
+//      foo := &pb.Foo{...}
+//      any, err := ptypes.MarshalAny(foo)
+//      ...
+//      foo := &pb.Foo{}
+//      if err := ptypes.UnmarshalAny(any, foo); err != nil {
+//        ...
+//      }
+//
+// The pack methods provided by protobuf library will by default use
+// 'type.googleapis.com/full.type.name' as the type URL and the unpack
+// methods only use the fully qualified type name after the last '/'
+// in the type URL, for example "foo.bar.com/x/y.z" will yield type
+// name "y.z".
+//
+//
+// JSON
+// ====
+// The JSON representation of an `Any` value uses the regular
+// representation of the deserialized, embedded message, with an
+// additional field `@type` which contains the type URL. Example:
+//
+//     package google.profile;
+//     message Person {
+//       string first_name = 1;
+//       string last_name = 2;
+//     }
+//
+//     {
+//       "@type": "type.googleapis.com/google.profile.Person",
+//       "firstName": <string>,
+//       "lastName": <string>
+//     }
+//
+// If the embedded message type is well-known and has a custom JSON
+// representation, that representation will be embedded adding a field
+// `value` which holds the custom JSON in addition to the `@type`
+// field. Example (for message [google.protobuf.Duration][]):
+//
+//     {
+//       "@type": "type.googleapis.com/google.protobuf.Duration",
+//       "value": "1.212s"
+//     }
+//
+message Any {
+  // A URL/resource name whose content describes the type of the
+  // serialized protocol buffer message.
+  //
+  // For URLs which use the scheme `http`, `https`, or no scheme, the
+  // following restrictions and interpretations apply:
+  //
+  // * If no scheme is provided, `https` is assumed.
+  // * The last segment of the URL's path must represent the fully
+  //   qualified name of the type (as in `path/google.protobuf.Duration`).
+  //   The name should be in a canonical form (e.g., leading "." is
+  //   not accepted).
+  // * An HTTP GET on the URL must yield a [google.protobuf.Type][]
+  //   value in binary format, or produce an error.
+  // * Applications are allowed to cache lookup results based on the
+  //   URL, or have them precompiled into a binary to avoid any
+  //   lookup. Therefore, binary compatibility needs to be preserved
+  //   on changes to types. (Use versioned type names to manage
+  //   breaking changes.)
+  //
+  // Schemes other than `http`, `https` (or the empty scheme) might be
+  // used with implementation specific semantics.
+  //
+  string type_url = 1;
+
+  // Must be a valid serialized protocol buffer of the above specified type.
+  bytes value = 2;

+// A Duration represents a signed, fixed-length span of time represented
+// as a count of seconds and fractions of seconds at nanosecond
+// resolution. It is independent of any calendar and concepts like "day"
+// or "month". It is related to Timestamp in that the difference between
+// two Timestamp values is a Duration and it can be added or subtracted
+// from a Timestamp. Range is approximately +-10,000 years.
+//
+// # Examples
+//
+// Example 1: Compute Duration from two Timestamps in pseudo code.
+//
+//     Timestamp start = ...;
+//     Timestamp end = ...;
+//     Duration duration = ...;

+//       duration.seconds -= 1;
+//       duration.nanos += 1000000000;
+//     }
+//
+// Example 2: Compute Timestamp from Timestamp + Duration in pseudo code.
+//
+//     Timestamp start = ...;
+//     Duration duration = ...;
+//     Timestamp end = ...;
+//
+//     end.seconds = start.seconds + duration.seconds;
+//     end.nanos = start.nanos + duration.nanos;
+//
+//     if (end.nanos < 0) {
+//       end.seconds -= 1;
+//       end.nanos += 1000000000;
+//     } else if (end.nanos >= 1000000000) {
+//       end.seconds += 1;
+//       end.nanos -= 1000000000;
+//     }
+//
+// Example 3: Compute Duration from datetime.timedelta in Python.
+//
+//     td = datetime.timedelta(days=3, minutes=10)
+//     duration = Duration()
+//     duration.FromTimedelta(td)
+//
+// # JSON Mapping
+//
+// In JSON format, the Duration type is encoded as a string rather than an
+// object, where the string ends in the suffix "s" (indicating seconds) and
+// is preceded by the number of seconds, with nanoseconds expressed as
+// fractional seconds. For example, 3 seconds with 0 nanoseconds should be

+//
+// Example 5: Compute Timestamp from current time in Python.
+//
+//     timestamp = Timestamp()
+//     timestamp.GetCurrentTime()
+//
+// # JSON Mapping
+//
+// In JSON format, the Timestamp type is encoded as a string in the
+// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+// where {year} is always expressed using four digits while {month}, {day},
+// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+// is required, though only UTC (as indicated by "Z") is presently supported.
+//
+// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+// 01:30 UTC on January 15, 2017.
+//
+// In JavaScript, one can convert a Date object to this format using the
+// standard [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString]
+// method. In Python, a standard `datetime.datetime` object can be converted
+// to this format using [`strftime`](https://docs.python.org/2/library/time.html#time.strftime)

+// seconds long, i.e. leap seconds are "smeared" so that no leap second
+// table is needed for interpretation. Range is from

+// See [https://www.ietf.org/rfc/rfc3339.txt](https://www.ietf.org/rfc/rfc3339.txt).
+//
+// # Examples
+//
+// Example 1: Compute Timestamp from POSIX `time()`.
+//
+//     Timestamp timestamp;
+//     timestamp.set_seconds(time(NULL));
+//     timestamp.set_nanos(0);
+//
+// Example 2: Compute Timestamp from POSIX `gettimeofday()`.
+//
+//     struct timeval tv;
+//     gettimeofday(&tv, NULL);
+//
+//     Timestamp timestamp;
+//     timestamp.set_seconds(tv.tv_sec);
+//     timestamp.set_nanos(tv.tv_usec * 1000);
+//
+// Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
+//
+//     FILETIME ft;
+//     GetSystemTimeAsFileTime(&ft);
+//     UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
+//
+//     // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
+//     // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
+//     Timestamp timestamp;
+//     timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
+//     timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
+//
+// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
+//
+//     long millis = System.currentTimeMillis();
+//
+//     Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
+//         .setNanos((int) ((millis % 1000) * 1000000)).build();
+//
+//
+// Example 5: Compute Timestamp from current time in Python.
+//
+//     timestamp = Timestamp()
+//     timestamp.GetCurrentTime()
+//
+// # JSON Mapping
+//
+// In JSON format, the Timestamp type is encoded as a string in the
+// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+// where {year} is always expressed using four digits while {month}, {day},
+// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+// is required, though only UTC (as indicated by "Z") is presently supported.
+//
+// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+// 01:30 UTC on January 15, 2017.
+//
+// In JavaScript, one can convert a Date object to this format using the
+// standard [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString]
+// method. In Python, a standard `datetime.datetime` object can be converted
+// to this format using [`strftime`](https://docs.python.org/2/library/time.html#time.strftime)
+// with the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one
+// can use the Joda Time's [`ISODateTimeFormat.dateTime()`](
+// http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime--)
+// to obtain a formatter capable of generating timestamps in this format.
+//
+//
+message Timestamp {
+
+  // Represents seconds of UTC time since Unix epoch
+  // 1970-01-01T00:00:00Z. Must be from 0001-01-01T00:00:00Z to

+# BTree implementation for Go
+
+![Travis CI Build Status](https://api.travis-ci.org/google/btree.svg?branch=master)
+
+This package provides an in-memory B-Tree implementation for Go, useful as
+an ordered, mutable data structure.
+
+The API is based off of the wonderful
+http://godoc.org/github.com/petar/GoLLRB/llrb, and is meant to allow btree to
+act as a drop-in replacement for gollrb trees.
+
+See http://godoc.org/github.com/google/btree for documentation.

+//
+// btree implements an in-memory B-Tree for use as an ordered data structure.
+// It is not meant for persistent storage solutions.
+//
+// It has a flatter structure than an equivalent red-black or other binary tree,
+// which in some cases yields better memory usage and/or performance.
+// See some discussion on the matter here:
+//   http://google-opensource.blogspot.com/2013/01/c-containers-that-save-memory-and-time.html
+// Note, though, that this project is in no way related to the C++ B-Tree
+// implementation written about there.
+//
+// Within this tree, each node contains a slice of items and a (possibly nil)
+// slice of children.  For basic numeric values or raw structs, this can cause
+// efficiency differences when compared to equivalent C++ template code that
+// stores values in arrays within the node:
+//   * Due to the overhead of storing values as interfaces (each
+//     value needs to be stored as the value itself, then 2 words for the
+//     interface pointing to that value and its type), resulting in higher
+//     memory use.
+//   * Since interfaces can point to values anywhere in memory, values are
+//     most likely not stored in contiguous blocks, resulting in a higher
+//     number of cache misses.
+// These issues don't tend to matter, though, when working with strings or other
+// heap-allocated structures, since C++-equivalent structures also must store
+// pointers and also distribute their values across the heap.
+//
+// This implementation is designed to be a drop-in replacement to gollrb.LLRB
+// trees, (http://github.com/petar/gollrb), an excellent and probably the most
+// widely used ordered tree implementation in the Go ecosystem currently.
+// Its functions, therefore, exactly mirror those of
+// llrb.LLRB where possible.  Unlike gollrb, though, we currently don't
+// support storing multiple equivalent values.

+//       by this tree, nodes are added to the freelist until full.
+//   O(tree size):  when all nodes are owned by another tree, all nodes are

+# How to contribute #
+
+We'd love to accept your patches and contributions to this project.  There are
+a just a few small guidelines you need to follow.
+
+
+## Contributor License Agreement ##
+
+Contributions to any Google project must be accompanied by a Contributor
+License Agreement.  This is not a copyright **assignment**, it simply gives
+Google permission to use and redistribute your contributions as part of the
+project.
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an [individual
+    CLA][].
+
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA][].
+
+You generally only need to submit a CLA once, so if you've already submitted
+one (even if it was for a different project), you probably don't need to do it
+again.
+
+[individual CLA]: https://developers.google.com/open-source/cla/individual
+[corporate CLA]: https://developers.google.com/open-source/cla/corporate
+
+
+## Submitting a patch ##
+
+  1. It's generally best to start by opening a new issue describing the bug or
+     feature you're intending to fix.  Even if you think it's relatively minor,
+     it's helpful to know what people are working on.  Mention in the initial
+     issue that you are planning to work on that bug or feature so that it can
+     be assigned to you.
+
+  1. Follow the normal process of [forking][] the project, and setup a new
+     branch to work in.  It's important that each group of changes be done in
+     separate branches in order to ensure that a pull request only includes the
+     commits related to that bug or feature.
+
+  1. Go makes it very simple to ensure properly formatted code, so always run
+     `go fmt` on your code before committing it.  You should also run
+     [golint][] over your code.  As noted in the [golint readme][], it's not
+     strictly necessary that your code be completely "lint-free", but this will
+     help you find common style issues.
+
+  1. Any significant changes should almost always be accompanied by tests.  The
+     project already has good test coverage, so look at some of the existing
+     tests if you're unsure how to go about it.  [gocov][] and [gocov-html][]
+     are invaluable tools for seeing which parts of your code aren't being
+     exercised by your tests.
+
+  1. Do your best to have [well-formed commit messages][] for each change.
+     This provides consistency throughout the project, and ensures that commit
+     messages are able to be formatted properly by various git tools.
+
+  1. Finally, push the commits to your fork and submit a [pull request][].

+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify

+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+gofuzz
+======
+
+gofuzz is a library for populating go objects with random values.
+
+[![GoDoc](https://godoc.org/github.com/google/gofuzz?status.png)](https://godoc.org/github.com/google/gofuzz)
+[![Travis](https://travis-ci.org/google/gofuzz.svg?branch=master)](https://travis-ci.org/google/gofuzz)
+
+This is useful for testing:
+
+* Do your project's objects really serialize/unserialize correctly in all cases?
+* Is there an incorrectly formatted object that will cause your project to panic?
+
+Import with ```import "github.com/google/gofuzz"```
+
+You can use it on single variables:
+```go
+f := fuzz.New()
+var myInt int
+f.Fuzz(&myInt) // myInt gets a random value.
+```
+
+You can use it on maps:
+```go
+f := fuzz.New().NilChance(0).NumElements(1, 1)
+var myMap map[ComplexKeyType]string
+f.Fuzz(&myMap) // myMap will have exactly one element.
+```
+
+Customize the chance of getting a nil pointer:
+```go
+f := fuzz.New().NilChance(.5)
+var fancyStruct struct {
+  A, B, C, D *string
+}
+f.Fuzz(&fancyStruct) // About half the pointers should be set.
+```
+
+You can even customize the randomization completely if needed:
+```go
+type MyEnum string
+const (
+        A MyEnum = "A"
+        B MyEnum = "B"
+)
+type MyInfo struct {
+        Type MyEnum
+        AInfo *string
+        BInfo *string
+}
+
+f := fuzz.New().NilChance(0).Funcs(
+        func(e *MyInfo, c fuzz.Continue) {

+# OpenAPI v2 Protocol Buffer Models
+
+This directory contains a Protocol Buffer-language model
+and related code for supporting OpenAPI v2.
+
+Gnostic applications and plugins can use OpenAPIv2.proto
+to generate Protocol Buffer support code for their preferred languages.
+
+OpenAPIv2.go is used by Gnostic to read JSON and YAML OpenAPI 
+descriptions into the Protocol Buffer-based datastructures 
+generated from OpenAPIv2.proto.
+
+OpenAPIv2.proto and OpenAPIv2.go are generated by the Gnostic 
+compiler generator, and OpenAPIv2.pb.go is generated by 
+protoc, the Protocol Buffer compiler, and protoc-gen-go, the
+Protocol Buffer Go code generation plugin.

+=========
+
+[![Build Status](https://travis-ci.org/gregjones/httpcache.svg?branch=master)](https://travis-ci.org/gregjones/httpcache) [![GoDoc](https://godoc.org/github.com/gregjones/httpcache?status.svg)](https://godoc.org/github.com/gregjones/httpcache)
+
+Package httpcache provides a http.RoundTripper implementation that works as a mostly [RFC 7234](https://tools.ietf.org/html/rfc7234) compliant cache for http responses.
+
+It is only suitable for use as a 'private' cache (i.e. for a web-browser or an API-client and not for a shared proxy).
+
+Cache Backends
+--------------
+
+- The built-in 'memory' cache stores responses in an in-memory map.
+- [`github.com/gregjones/httpcache/diskcache`](https://github.com/gregjones/httpcache/tree/master/diskcache) provides a filesystem-backed cache using the [diskv](https://github.com/peterbourgon/diskv) library.
+- [`github.com/gregjones/httpcache/memcache`](https://github.com/gregjones/httpcache/tree/master/memcache) provides memcache implementations, for both App Engine and 'normal' memcache servers.
+- [`sourcegraph.com/sourcegraph/s3cache`](https://sourcegraph.com/github.com/sourcegraph/s3cache) uses Amazon S3 for storage.
+- [`github.com/gregjones/httpcache/leveldbcache`](https://github.com/gregjones/httpcache/tree/master/leveldbcache) provides a filesystem-backed cache using [leveldb](https://github.com/syndtr/goleveldb/leveldb).
+- [`github.com/die-net/lrucache`](https://github.com/die-net/lrucache) provides an in-memory cache that will evict least-recently used entries.
+- [`github.com/die-net/lrucache/twotier`](https://github.com/die-net/lrucache/tree/master/twotier) allows caches to be combined, for example to use lrucache above with a persistent disk-cache.
+- [`github.com/birkelund/boltdbcache`](https://github.com/birkelund/boltdbcache) provides a BoltDB implementation (based on the [bbolt](https://github.com/coreos/bbolt) fork).

+
+     a. under intellectual property rights (other than patent or trademark)
+        Licensable by such Contributor to use, reproduce, make available,
+        modify, display, perform, distribute, and otherwise exploit its
+        Contributions, either on an unmodified basis, with Modifications, or

+
+     b. under Patent Claims of such Contributor to make, use, sell, offer for
+        sale, have made, import, and otherwise transfer either its
+        Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+     The licenses granted in Section 2.1 with respect to any Contribution
+     become effective for each Contribution on the date the Contributor first
+     distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+     The licenses granted in this Section 2 are the only rights granted under
+     this License. No additional rights or licenses will be implied from the
+     distribution or licensing of Covered Software under this License.
+     Notwithstanding Section 2.1(b) above, no patent license is granted by a
+     Contributor:
+
+     a. for any code that a Contributor has removed from Covered Software; or
+
+     b. for infringements caused by: (i) Your and any other third party's
+        modifications of Covered Software, or (ii) the combination of its
+        Contributions with other software (except as part of its Contributor
+        Version); or
+
+     c. under Patent Claims infringed by Covered Software in the absence of
+        its Contributions.
+
+     This License does not grant any rights in the trademarks, service marks,
+     or logos of any Contributor (except as may be necessary to comply with
+     the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+     No Contributor makes additional grants as a result of Your choice to
+     distribute the Covered Software under a subsequent version of this
+     License (see Section 10.2) or under the terms of a Secondary License (if
+     permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+     Each Contributor represents that the Contributor believes its
+     Contributions are its original creation(s) or it has sufficient rights to
+     grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+     This License is not intended to limit any rights You have under
+     applicable copyright doctrines of fair use, fair dealing, or other
+     equivalents.
+
+2.7. Conditions
+
+     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
+     Section 2.1.
+
+
+3. Responsibilities
+
+3.1. Distribution of Source Form
+
+     All distribution of Covered Software in Source Code Form, including any
+     Modifications that You create or to which You contribute, must be under
+     the terms of this License. You must inform recipients that the Source
+     Code Form of the Covered Software is governed by the terms of this
+     License, and how they can obtain a copy of this License. You may not
+     attempt to alter or restrict the recipients' rights in the Source Code
+     Form.
+
+3.2. Distribution of Executable Form
+
+     If You distribute Covered Software in Executable Form then:
+
+     a. such Covered Software must also be made available in Source Code Form,
+        as described in Section 3.1, and You must inform recipients of the
+        Executable Form how they can obtain a copy of such Source Code Form by
+        reasonable means in a timely manner, at a charge no more than the cost
+        of distribution to the recipient; and
+
+     b. You may distribute such Executable Form under the terms of this
+        License, or sublicense it under different terms, provided that the
+        license for the Executable Form does not attempt to limit or alter the
+        recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+     You may create and distribute a Larger Work under terms of Your choice,
+     provided that You also comply with the requirements of this License for
+     the Covered Software. If the Larger Work is a combination of Covered
+     Software with a work governed by one or more Secondary Licenses, and the
+     Covered Software is not Incompatible With Secondary Licenses, this
+     License permits You to additionally distribute such Covered Software
+     under the terms of such Secondary License(s), so that the recipient of
+     the Larger Work may, at their option, further distribute the Covered
+     Software under the terms of either this License or such Secondary
+     License(s).
+
+3.4. Notices
+
+     You may not remove or alter the substance of any license notices
+     (including copyright notices, patent notices, disclaimers of warranty, or
+     limitations of liability) contained within the Source Code Form of the
+     Covered Software, except that You may alter any license notices to the
+     extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+     You may choose to offer, and to charge a fee for, warranty, support,
+     indemnity or liability obligations to one or more recipients of Covered
+     Software. However, You may do so only on Your own behalf, and not on
+     behalf of any Contributor. You must make it absolutely clear that any
+     such warranty, support, indemnity, or liability obligation is offered by
+     You alone, and You hereby agree to indemnify every Contributor for any
+     liability incurred by such Contributor as a result of warranty, support,
+     indemnity or liability terms You offer. You may include additional
+     disclaimers of warranty and limitations of liability specific to any
+     jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+   If it is impossible for You to comply with any of the terms of this License
+   with respect to some or all of the Covered Software due to statute,
+   judicial order, or regulation then You must: (a) comply with the terms of
+   this License to the maximum extent possible; and (b) describe the
+   limitations and the code they affect. Such description must be placed in a
+   text file included with all distributions of the Covered Software under
+   this License. Except to the extent prohibited by statute or regulation,
+   such description must be sufficiently detailed for a recipient of ordinary
+   skill to be able to understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+     fail to comply with any of its terms. However, if You become compliant,
+     then the rights granted under this License from a particular Contributor
+     are reinstated (a) provisionally, unless and until such Contributor
+     explicitly and finally terminates Your grants, and (b) on an ongoing
+     basis, if such Contributor fails to notify You of the non-compliance by
+     some reasonable means prior to 60 days after You have come back into
+     compliance. Moreover, Your grants from a particular Contributor are
+     reinstated on an ongoing basis if such Contributor notifies You of the
+     non-compliance by some reasonable means, this is the first time You have
+     received notice of non-compliance with this License from such
+     Contributor, and You become compliant prior to 30 days after Your receipt
+     of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+     infringement claim (excluding declaratory judgment actions,
+     counter-claims, and cross-claims) alleging that a Contributor Version
+     directly or indirectly infringes any patent, then the rights granted to
+     You by any and all Contributors for the Covered Software under Section
+     2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+     license agreements (excluding distributors and resellers) which have been
+     validly granted by You or Your distributors under this License prior to
+     termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+   Covered Software is provided under this License on an "as is" basis,
+   without warranty of any kind, either expressed, implied, or statutory,
+   including, without limitation, warranties that the Covered Software is free
+   of defects, merchantable, fit for a particular purpose or non-infringing.
+   The entire risk as to the quality and performance of the Covered Software
+   is with You. Should any Covered Software prove defective in any respect,
+   You (not any Contributor) assume the cost of any necessary servicing,
+   repair, or correction. This disclaimer of warranty constitutes an essential
+   part of this License. No use of  any Covered Software is authorized under
+   this License except under this disclaimer.
+
+7. Limitation of Liability
+
+   Under no circumstances and under no legal theory, whether tort (including
+   negligence), contract, or otherwise, shall any Contributor, or anyone who
+   distributes Covered Software as permitted above, be liable to You for any
+   direct, indirect, special, incidental, or consequential damages of any
+   character including, without limitation, damages for lost profits, loss of
+   goodwill, work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses, even if such party shall have been
+   informed of the possibility of such damages. This limitation of liability
+   shall not apply to liability for death or personal injury resulting from
+   such party's negligence to the extent applicable law prohibits such
+   limitation. Some jurisdictions do not allow the exclusion or limitation of
+   incidental or consequential damages, so this exclusion and limitation may
+   not apply to You.
+
+8. Litigation
+
+   Any litigation relating to this License may be brought only in the courts
+   of a jurisdiction where the defendant maintains its principal place of
+   business and such litigation shall be governed by laws of that
+   jurisdiction, without reference to its conflict-of-law provisions. Nothing
+   in this Section shall prevent a party's ability to bring cross-claims or
+   counter-claims.
+
+9. Miscellaneous
+
+   This License represents the complete agreement concerning the subject
+   matter hereof. If any provision of this License is held to be
+   unenforceable, such provision shall be reformed only to the extent
+   necessary to make it enforceable. Any law or regulation which provides that
+   the language of a contract shall be construed against the drafter shall not
+   be used to construe this License against a Contributor.
+
+
+10. Versions of the License
+
+10.1. New Versions
+
+      Mozilla Foundation is the license steward. Except as provided in Section
+      10.3, no one other than the license steward has the right to modify or
+      publish new versions of this License. Each version will be given a
+      distinguishing version number.
+
+10.2. Effect of New Versions
+
+      You may distribute the Covered Software under the terms of the version
+      of the License under which You originally received the Covered Software,
+      or under the terms of any subsequent version published by the license
+      steward.
+
+10.3. Modified Versions
+
+      If you create software not governed by this License, and you want to
+      create a new license for such software, you may create and use a
+      modified version of this License if you rename the license and remove
+      any references to the name of the license steward (except to note that
+      such modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary
+      Licenses If You choose to distribute Source Code Form that is
+      Incompatible With Secondary Licenses under the terms of this version of
+      the License, the notice described in Exhibit B of this License must be
+      attached.

+golang-lru
+==========
+
+This provides the `lru` package which implements a fixed-size
+thread safe LRU cache. It is based on the cache in Groupcache.
+
+Documentation
+=============
+
+Full docs are available on [Godoc](http://godoc.org/github.com/hashicorp/golang-lru)
+
+Example
+=======
+
+Using the LRU is very simple:
+
+```go
+l, _ := New(128)
+for i := 0; i < 256; i++ {
+    l.Add(i, nil)
+}
+if l.Len() != 128 {
+    panic(fmt.Sprintf("bad len: %v", l.Len()))
+}
+```

+// https://github.com/golang/groupcache/tree/master/lru
+//
+// TwoQueueCache tracks frequently used and recently used entries separately.
+// This avoids a burst of accesses from taking out frequently used entries,
+// at the cost of about 2x computational overhead and some extra bookkeeping.
+//
+// ARCCache is an adaptive replacement cache. It tracks recent evictions as
+// well as recent usage in both the frequent and recent caches. Its
+// computational overhead is comparable to TwoQueueCache, but the memory
+// overhead is linear with the size of the cache.
+//
+// ARC has been patented by IBM, so do not use it if that is problematic for
+// your program.
+//
+// All caches in this package take locks while operating, and are therefore
+// thread-safe for consumers.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community.

+# Mergo
+
+A helper to merge structs and maps in Golang. Useful for configuration default values, avoiding messy if-statements.
+
+Also a lovely [comune](http://en.wikipedia.org/wiki/Mergo) (municipality) in the Province of Ancona in the Italian region of Marche.
+
+## Status
+
+It is ready for production use. [It is used in several projects by Docker, Google, The Linux Foundation, VMWare, Shopify, etc](https://github.com/imdario/mergo#mergo-in-the-wild).

+### Latest release
+
+[Release v0.3.4](https://github.com/imdario/mergo/releases/tag/v0.3.4).
+
+### Important note
+
+Please keep in mind that in [0.3.2](//github.com/imdario/mergo/releases/tag/0.3.2) Mergo changed `Merge()`and `Map()` signatures to support [transformers](#transformers). An optional/variadic argument has been added, so it won't break existing code.
+
+If you were using Mergo **before** April 6th 2015, please check your project works as intended after updating your local copy with ```go get -u github.com/imdario/mergo```. I apologize for any issue caused by its previous behavior and any future bug that Mergo could cause (I hope it won't!) in existing projects after the change (release 0.2.0).
+
+### Donations
+
+If Mergo is useful to you, consider buying me a coffee, a beer or making a monthly donation so I can keep building great free software. :heart_eyes:

+## Installation
+
+    go get github.com/imdario/mergo
+
+    // use in your .go code
+    import (
+        "github.com/imdario/mergo"
+    )
+
+## Usage
+
+You can only merge same-type structs with exported fields initialized as zero value of their type and same-types maps. Mergo won't merge unexported (private) fields but will do recursively any exported one. It won't merge empty structs value as [they are not considered zero values](https://golang.org/ref/spec#The_zero_value) either. Also maps will be merged recursively except for structs inside maps (because they are not addressable using Go reflection).
+
+```go
+if err := mergo.Merge(&dst, src); err != nil {
+    // ...
+}
+```
+
+Also, you can merge overwriting values using the transformer `WithOverride`.
+
+```go
+if err := mergo.Merge(&dst, src, mergo.WithOverride); err != nil {
+    // ...
+}
+```
+
+Additionally, you can map a `map[string]interface{}` to a struct (and otherwise, from struct to map), following the same restrictions as in `Merge()`. Keys are capitalized to find each corresponding exported field.
+
+```go
+if err := mergo.Map(&dst, srcMap); err != nil {
+    // ...
+}
+```
+
+Warning: if you map a struct to map, it won't do it recursively. Don't expect Mergo to map struct members of your struct as `map[string]interface{}`. They will be just assigned as values.
+
+More information and examples in [godoc documentation](http://godoc.org/github.com/imdario/mergo).
+
+### Nice example
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/imdario/mergo"
+)
+
+type Foo struct {
+	A string
+	B int64
+}
+
+func main() {
+	src := Foo{
+		A: "one",
+		B: 2,
+	}
+	dest := Foo{
+		A: "two",
+	}
+	mergo.Merge(&dest, src)
+	fmt.Println(dest)
+	// Will print
+	// {two 2}
+}
+```
+
+Note: if test are failing due missing package, please execute:
+
+    go get gopkg.in/yaml.v2
+
+### Transformers
+
+Transformers allow to merge specific types differently than in the default behavior. In other words, now you can customize how some types are merged. For example, `time.Time` is a struct; it doesn't have zero value but IsZero can return true because it has fields with zero value. How can we merge a non-zero `time.Time`?
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/imdario/mergo"
+        "reflect"
+        "time"
+)
+
+type timeTransfomer struct {
+}
+
+func (t timeTransfomer) Transformer(typ reflect.Type) func(dst, src reflect.Value) error {
+	if typ == reflect.TypeOf(time.Time{}) {
+		return func(dst, src reflect.Value) error {
+			if dst.CanSet() {
+				isZero := dst.MethodByName("IsZero")
+				result := isZero.Call([]reflect.Value{})
+				if result[0].Bool() {
+					dst.Set(src)
+				}
+			}
+			return nil
+		}
+	}
+	return nil
+}
+
+type Snapshot struct {
+	Time time.Time
+	// ...
+}
+
+func main() {
+	src := Snapshot{time.Now()}
+	dest := Snapshot{}
+	mergo.Merge(&dest, src, mergo.WithTransformers(timeTransfomer{}))
+	fmt.Println(dest)
+	// Will print
+	// { 2018-01-12 01:15:00 +0000 UTC m=+0.000000001 }
+}
+```

+Package mergo merges same-type structs and maps by setting default values in zero-value fields.
+
+Mergo won't merge unexported (private) fields but will do recursively any exported one. It also won't merge structs inside maps (because they are not addressable using Go reflection).
+
+Usage
+
+From my own work-in-progress project:
+
+	type networkConfig struct {
+		Protocol string
+		Address string
+		ServerType string `json: "server_type"`
+		Port uint16
+	}
+
+	type FssnConfig struct {
+		Network networkConfig
+	}
+
+	var fssnDefault = FssnConfig {
+		networkConfig {
+			"tcp",
+			"127.0.0.1",
+			"http",
+			31560,
+		},
+	}
+
+	// Inside a function [...]
+
+	if err := mergo.Merge(&config, fssnDefault); err != nil {
+		log.Fatal(err)
+	}
+
+	// More code [...]

+# mousetrap
+
+mousetrap is a tiny library that answers a single question.
+
+On a Windows machine, was the process invoked by someone double clicking on
+the executable file while browsing in explorer?
+
+### Motivation
+
+Windows developers unfamiliar with command line tools will often "double-click"
+the executable for a tool. Because most CLI tools print the help and then exit
+when invoked without arguments, this is often very frustrating for those users.
+
+mousetrap provides a way to detect these invocations so that you can provide
+more helpful behavior and instructions on how to run the CLI tool. To see what
+this looks like, both from an organizational and a technical perspective, see
+https://inconshreveable.com/09-09-2014/sweat-the-small-stuff/
+
+### The interface
+
+The library exposes a single interface:
+
+    func StartedByExplorer() (bool)

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,

+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+
+reflect api that avoids runtime reflect.Value cost
+
+* reflect get/set interface{}, with type checking
+* reflect get/set unsafe.Pointer, without type checking
+* `reflect2.TypeByName` works like `Class.forName` found in java
+
+[json-iterator](https://github.com/json-iterator/go) use this package to save runtime dispatching cost.
+This package is designed for low level libraries to optimize reflection performance.
+General application should still use reflect standard library.
+
+# reflect2.TypeByName
+
+```go
+// given package is github.com/your/awesome-package
+type MyStruct struct {
+	// ...
+}
+
+// will return the type
+reflect2.TypeByName("awesome-package.MyStruct")
+// however, if the type has not been used
+// it will be eliminated by compiler, so we can not get it in runtime
+```
+
+# reflect2 get/set interface{}
+
+```go
+valType := reflect2.TypeOf(1)
+i := 1
+j := 10
+valType.Set(&i, &j)
+// i will be 10
+```
+
+to get set `type`, always use its pointer `*type`
+
+# reflect2 get/set unsafe.Pointer
+
+```go
+valType := reflect2.TypeOf(1)
+i := 1
+j := 10
+valType.UnsafeSet(unsafe.Pointer(&i), unsafe.Pointer(&j))
+// i will be 10
+```
+
+to get set `type`, always use its pointer `*type`
+
+# benchmark
+
+Benchmark is not necessary for this package. It does nothing actually.
+As it is just a thin wrapper to make go runtime public. 
+Both `reflect2` and `reflect` call same function 
+provided by `runtime` package exposed by go language.
+
+# unsafe safety
+
+Instead of casting `[]byte` to `sliceHeader` in your application using unsafe.
+We can use reflect2 instead. This way, if `sliceHeader` changes in the future,
+only reflect2 need to be upgraded.
+
+reflect2 tries its best to keep the implementation same as reflect (by testing).

+## 1.5.0 5/10/2018
+
+### New Features
+- Supports go v1.10 (#443, #446, #451) [e873237, 468e89e, e37dbfe, a37f4c0, c0b857d, bca5260, 4177ca8]
+- Add a When() synonym for Context() (#386) [747514b, 7484dad, 7354a07, dd826c8]
+- Re-add noisySkippings flag [652e15c]
+- Allow coverage to be displayed for focused specs (#367) [11459a8]
+- Handle -outputdir flag (#364) [228e3a8]
+- Handle -coverprofile flag (#355) [43392d5]
+
+### Fixes
+- When using custom reporters register the custom reporters *before* the default reporter.  This allows users to see the output of any print statements in their customer reporters. (#365) [8382b23]
+- When running a test and calculating the coverage using the `-coverprofile` and `-outputdir` flags, Ginkgo fails with an error if the directory does not exist. This is due to an [issue in go 1.10](https://github.com/golang/go/issues/24588) (#446) [b36a6e0]
+- `unfocus` command ignores vendor folder (#459) [e5e551c, c556e43, a3b6351, 9a820dd]
+- Ignore packages whose tests are all ignored by go (#456) [7430ca7, 6d8be98]
+- Increase the threshold when checking time measuments (#455) [2f714bf, 68f622c]
+- Fix race condition in coverage tests (#423) [a5a8ff7, ab9c08b]
+- Add an extra new line after reporting spec run completion for test2json [874520d]
+- added name name field to junit reported testsuite [ae61c63]
+- Do not set the run time of a spec when the dryRun flag is used (#438) [457e2d9, ba8e856]
+- Process FWhen and FSpecify when unfocusing (#434) [9008c7b, ee65bd, df87dfe]
+- Synchronise the access to the state of specs to avoid race conditions (#430) [7d481bc, ae6829d]
+- Added Duration on GinkgoTestDescription (#383) [5f49dad, 528417e, 0747408, 329d7ed]
+- Fix Ginkgo stack trace on failure for Specify (#415) [b977ede, 65ca40e, 6c46eb8]
+- Update README with Go 1.6+, Golang -> Go (#409) [17f6b97, bc14b66, 20d1598]
+- Use fmt.Errorf instead of errors.New(fmt.Sprintf (#401) [a299f56, 44e2eaa]
+- Imports in generated code should follow conventions (#398) [0bec0b0, e8536d8]
+- Prevent data race error when Recording a benchmark value from multiple go routines (#390) [c0c4881, 7a241e9]
+- Replace GOPATH in Environment [4b883f0]
+
+
+## 1.4.0 7/16/2017
+
+- `ginkgo` now provides a hint if you accidentally forget to run `ginkgo bootstrap` to generate a `*_suite_test.go` file that actually invokes the Ginkgo test runner. [#345](https://github.com/onsi/ginkgo/pull/345)
+- thanks to improvements in `go test -c` `ginkgo` no longer needs to fix Go's compilation output to ensure compilation errors are expressed relative to the CWD. [#357]
+- `ginkgo watch -watchRegExp=...` allows you to specify a custom regular expression to watch.  Only files matching the regular expression are watched for changes (the default is `\.go$`) [#356]
+- `ginkgo` now always emits compilation output.  Previously, only failed compilation output was printed out. [#277]
+- `ginkgo -requireSuite` now fails the test run if there are `*_test.go` files but `go test` fails to detect any tests.  Typically this means you forgot to run `ginkgo bootstrap` to generate a suite file. [#344]
+- `ginkgo -timeout=DURATION` allows you to adjust the timeout for the entire test suite (default is 24 hours) [#248]
+
+## 1.3.0 3/28/2017
+
+Improvements:
+
+- Significantly improved parallel test distribution.  Now instead of pre-sharding test cases across workers (which can result in idle workers and poor test performance) Ginkgo uses a shared queue to keep all workers busy until all tests are complete.  This improves test-time performance and consistency.
+- `Skip(message)` can be used to skip the current test.
+- Added `extensions/table` - a Ginkgo DSL for [Table Driven Tests](http://onsi.github.io/ginkgo/#table-driven-tests)
+- Add `GinkgoRandomSeed()` - shorthand for `config.GinkgoConfig.RandomSeed`
+- Support for retrying flaky tests with `--flakeAttempts`
+- `ginkgo ./...` now recurses as you'd expect
+- Added `Specify` a synonym for `It`
+- Support colorise on Windows
+- Broader support for various go compilation flags in the `ginkgo` CLI
+
+Bug Fixes:
+
+- Ginkgo tests now fail when you `panic(nil)` (#167)
+
+## 1.2.0 5/31/2015
+
+Improvements
+
+- `ginkgo -coverpkg` calls down to `go test -coverpkg` (#160)
+- `ginkgo -afterSuiteHook COMMAND` invokes the passed-in `COMMAND` after a test suite completes (#152)
+- Relaxed requirement for Go 1.4+.  `ginkgo` now works with Go v1.3+ (#166)
+
+## 1.2.0-beta
+
+Ginkgo now requires Go 1.4+
+
+Improvements:
+
+- Call reporters in reverse order when announcing spec completion -- allows custom reporters to emit output before the default reporter does.
+- Improved focus behavior.  Now, this:
+
+    ```golang
+    FDescribe("Some describe", func() {
+        It("A", func() {})
+
+        FIt("B", func() {})
+    })
+    ```
+
+  will run `B` but *not* `A`.  This tends to be a common usage pattern when in the thick of writing and debugging tests.
+- When `SIGINT` is received, Ginkgo will emit the contents of the `GinkgoWriter` before running the `AfterSuite`.  Useful for debugging stuck tests.
+- When `--progress` is set, Ginkgo will write test progress (in particular, Ginkgo will say when it is about to run a BeforeEach, AfterEach, It, etc...) to the `GinkgoWriter`.  This is useful for debugging stuck tests and tests that generate many logs.
+- Improved output when an error occurs in a setup or teardown block.
+- When `--dryRun` is set, Ginkgo will walk the spec tree and emit to its reporter *without* actually running anything.  Best paired with `-v` to understand which specs will run in which order.
+- Add `By` to help document long `It`s.  `By` simply writes to the `GinkgoWriter`.
+- Add support for precompiled tests:
+    - `ginkgo build <path-to-package>` will now compile the package, producing a file named `package.test`
+    - The compiled `package.test` file can be run directly.  This runs the tests in series.
+    - To run precompiled tests in parallel, you can run: `ginkgo -p package.test`
+- Support `bootstrap`ping and `generate`ing [Agouti](http://agouti.org) specs.
+- `ginkgo generate` and `ginkgo bootstrap` now honor the package name already defined in a given directory
+- The `ginkgo` CLI ignores `SIGQUIT`.  Prevents its stack dump from interlacing with the underlying test suite's stack dump.
+- The `ginkgo` CLI now compiles tests into a temporary directory instead of the package directory.  This necessitates upgrading to Go v1.4+.
+- `ginkgo -notify` now works on Linux
+
+Bug Fixes:
+
+- If --skipPackages is used and all packages are skipped, Ginkgo should exit 0.
+- Fix tempfile leak when running in parallel
+- Fix incorrect failure message when a panic occurs during a parallel test run
+- Fixed an issue where a pending test within a focused context (or a focused test within a pending context) would skip all other tests.
+- Be more consistent about handling SIGTERM as well as SIGINT
+- When interupted while concurrently compiling test suites in the background, Ginkgo now cleans up the compiled artifacts.
+- Fixed a long standing bug where `ginkgo -p` would hang if a process spawned by one of the Ginkgo parallel nodes does not exit. (Hooray!)
+
+## 1.1.0 (8/2/2014)
+
+No changes, just dropping the beta.
+
+## 1.1.0-beta (7/22/2014)
+New Features:
+
+- `ginkgo watch` now monitors packages *and their dependencies* for changes.  The depth of the dependency tree can be modified with the `-depth` flag.
+- Test suites with a programmatic focus (`FIt`, `FDescribe`, etc...) exit with non-zero status code, even when they pass.  This allows CI systems to detect accidental commits of focused test suites.
+- `ginkgo -p` runs the testsuite in parallel with an auto-detected number of nodes.
+- `ginkgo -tags=TAG_LIST` passes a list of tags down to the `go build` command.
+- `ginkgo --failFast` aborts the test suite after the first failure.
+- `ginkgo generate file_1 file_2` can take multiple file arguments.
+- Ginkgo now summarizes any spec failures that occured at the end of the test run. 
+- `ginkgo --randomizeSuites` will run tests *suites* in random order using the generated/passed-in seed.
+
+Improvements:
+
+- `ginkgo -skipPackage` now takes a comma-separated list of strings.  If the *relative path* to a package matches one of the entries in the comma-separated list, that package is skipped.
+- `ginkgo --untilItFails` no longer recompiles between attempts.
+- Ginkgo now panics when a runnable node (`It`, `BeforeEach`, `JustBeforeEach`, `AfterEach`, `Measure`) is nested within another runnable node.  This is always a mistake.  Any test suites that panic because of this change should be fixed.
+
+Bug Fixes:
+
+- `ginkgo boostrap` and `ginkgo generate` no longer fail when dealing with `hyphen-separated-packages`.
+- parallel specs are now better distributed across nodes - fixed a crashing bug where (for example) distributing 11 tests across 7 nodes would panic
+
+## 1.0.0 (5/24/2014)
+New Features:
+
+- Add `GinkgoParallelNode()` - shorthand for `config.GinkgoConfig.ParallelNode`
+
+Improvements:
+
+- When compilation fails, the compilation output is rewritten to present a correct *relative* path.  Allows ⌘-clicking in iTerm open the file in your text editor.
+- `--untilItFails` and `ginkgo watch` now generate new random seeds between test runs, unless a particular random seed is specified.
+
+Bug Fixes:
+
+- `-cover` now generates a correctly combined coverprofile when running with in parallel with multiple `-node`s.
+- Print out the contents of the `GinkgoWriter` when `BeforeSuite` or `AfterSuite` fail.
+- Fix all remaining race conditions in Ginkgo's test suite.
+
+## 1.0.0-beta (4/14/2014)
+Breaking changes:
+
+- `thirdparty/gomocktestreporter` is gone.  Use `GinkgoT()` instead
+- Modified the Reporter interface 
+- `watch` is now a subcommand, not a flag.
+
+DSL changes:
+
+- `BeforeSuite` and `AfterSuite` for setting up and tearing down test suites.
+- `AfterSuite` is triggered on interrupt (`^C`) as well as exit.
+- `SynchronizedBeforeSuite` and `SynchronizedAfterSuite` for setting up and tearing down singleton resources across parallel nodes.
+
+CLI changes:
+
+- `watch` is now a subcommand, not a flag
+- `--nodot` flag can be passed to `ginkgo generate` and `ginkgo bootstrap` to avoid dot imports.  This explicitly imports all exported identifiers in Ginkgo and Gomega.  Refreshing this list can be done by running `ginkgo nodot`
+- Additional arguments can be passed to specs.  Pass them after the `--` separator
+- `--skipPackage` flag takes a regexp and ignores any packages with package names passing said regexp.
+- `--trace` flag prints out full stack traces when errors occur, not just the line at which the error occurs.
+
+Misc:
+
+- Start using semantic versioning
+- Start maintaining changelog
+
+Major refactor:
+
+- Pull out Ginkgo's internal to `internal`
+- Rename `example` everywhere to `spec`
+- Much more!

+![Ginkgo: A Go BDD Testing Framework](http://onsi.github.io/ginkgo/images/ginkgo.png)
+
+[![Build Status](https://travis-ci.org/onsi/ginkgo.svg)](https://travis-ci.org/onsi/ginkgo)
+
+Jump to the [docs](http://onsi.github.io/ginkgo/) to learn more.  To start rolling your Ginkgo tests *now* [keep reading](#set-me-up)!
+
+If you have a question, comment, bug report, feature request, etc. please open a GitHub issue.
+
+## Feature List
+
+- Ginkgo uses Go's `testing` package and can live alongside your existing `testing` tests.  It's easy to [bootstrap](http://onsi.github.io/ginkgo/#bootstrapping-a-suite) and start writing your [first tests](http://onsi.github.io/ginkgo/#adding-specs-to-a-suite)
+
+- Structure your BDD-style tests expressively:
+    - Nestable [`Describe`, `Context` and `When` container blocks](http://onsi.github.io/ginkgo/#organizing-specs-with-containers-describe-and-context)
+    - [`BeforeEach` and `AfterEach` blocks](http://onsi.github.io/ginkgo/#extracting-common-setup-beforeeach) for setup and teardown
+    - [`It` and `Specify` blocks](http://onsi.github.io/ginkgo/#individual-specs-) that hold your assertions
+    - [`JustBeforeEach` blocks](http://onsi.github.io/ginkgo/#separating-creation-and-configuration-justbeforeeach) that separate creation from configuration (also known as the subject action pattern).
+    - [`BeforeSuite` and `AfterSuite` blocks](http://onsi.github.io/ginkgo/#global-setup-and-teardown-beforesuite-and-aftersuite) to prep for and cleanup after a suite.
+
+- A comprehensive test runner that lets you:
+    - Mark specs as [pending](http://onsi.github.io/ginkgo/#pending-specs)
+    - [Focus](http://onsi.github.io/ginkgo/#focused-specs) individual specs, and groups of specs, either programmatically or on the command line
+    - Run your tests in [random order](http://onsi.github.io/ginkgo/#spec-permutation), and then reuse random seeds to replicate the same order.
+    - Break up your test suite into parallel processes for straightforward [test parallelization](http://onsi.github.io/ginkgo/#parallel-specs)
+
+- `ginkgo`: a command line interface with plenty of handy command line arguments for [running your tests](http://onsi.github.io/ginkgo/#running-tests) and [generating](http://onsi.github.io/ginkgo/#generators) test files.  Here are a few choice examples:
+    - `ginkgo -nodes=N` runs your tests in `N` parallel processes and print out coherent output in realtime
+    - `ginkgo -cover` runs your tests using Go's code coverage tool
+    - `ginkgo convert` converts an XUnit-style `testing` package to a Ginkgo-style package
+    - `ginkgo -focus="REGEXP"` and `ginkgo -skip="REGEXP"` allow you to specify a subset of tests to run via regular expression
+    - `ginkgo -r` runs all tests suites under the current directory
+    - `ginkgo -v` prints out identifying information for each tests just before it runs
+
+    And much more: run `ginkgo help` for details!
+
+    The `ginkgo` CLI is convenient, but purely optional -- Ginkgo works just fine with `go test`
+
+- `ginkgo watch` [watches](https://onsi.github.io/ginkgo/#watching-for-changes) packages *and their dependencies* for changes, then reruns tests.  Run tests immediately as you develop!
+
+- Built-in support for testing [asynchronicity](http://onsi.github.io/ginkgo/#asynchronous-tests)
+
+- Built-in support for [benchmarking](http://onsi.github.io/ginkgo/#benchmark-tests) your code.  Control the number of benchmark samples as you gather runtimes and other, arbitrary, bits of numerical information about your code. 
+
+- [Completions for Sublime Text](https://github.com/onsi/ginkgo-sublime-completions): just use [Package Control](https://sublime.wbond.net/) to install `Ginkgo Completions`.
+
+- [Completions for VSCode](https://github.com/onsi/vscode-ginkgo): just use VSCode's extension installer to install `vscode-ginkgo`.
+
+- Straightforward support for third-party testing libraries such as [Gomock](https://code.google.com/p/gomock/) and [Testify](https://github.com/stretchr/testify).  Check out the [docs](http://onsi.github.io/ginkgo/#third-party-integrations) for details.
+
+- A modular architecture that lets you easily:
+    - Write [custom reporters](http://onsi.github.io/ginkgo/#writing-custom-reporters) (for example, Ginkgo comes with a [JUnit XML reporter](http://onsi.github.io/ginkgo/#generating-junit-xml-output) and a TeamCity reporter).
+    - [Adapt an existing matcher library (or write your own!)](http://onsi.github.io/ginkgo/#using-other-matcher-libraries) to work with Ginkgo
+
+## [Gomega](http://github.com/onsi/gomega): Ginkgo's Preferred Matcher Library
+
+Ginkgo is best paired with Gomega.  Learn more about Gomega [here](http://onsi.github.io/gomega/)
+
+## [Agouti](http://github.com/sclevine/agouti): A Go Acceptance Testing Framework
+
+Agouti allows you run WebDriver integration tests.  Learn more about Agouti [here](http://agouti.org)
+
+## Set Me Up!
+
+You'll need the Go command-line tools. Ginkgo is tested with Go 1.6+, but preferably you should get the latest. Follow the [installation instructions](https://golang.org/doc/install) if you don't have it installed.
+
+```bash
+
+go get -u github.com/onsi/ginkgo/ginkgo  # installs the ginkgo CLI
+go get -u github.com/onsi/gomega/...     # fetches the matcher library
+
+cd path/to/package/you/want/to/test
+
+ginkgo bootstrap # set up a new ginkgo suite
+ginkgo generate  # will create a sample test file.  edit this file and add your tests then...
+
+go test # to run your tests
+
+ginkgo  # also runs your tests
+
+```
+
+## I'm new to Go: What are my testing options?
+
+Of course, I heartily recommend [Ginkgo](https://github.com/onsi/ginkgo) and [Gomega](https://github.com/onsi/gomega).  Both packages are seeing heavy, daily, production use on a number of projects and boast a mature and comprehensive feature-set.
+
+With that said, it's great to know what your options are :)
+
+### What Go gives you out of the box
+
+Testing is a first class citizen in Go, however Go's built-in testing primitives are somewhat limited: The [testing](http://golang.org/pkg/testing) package provides basic XUnit style tests and no assertion library.
+
+### Matcher libraries for Go's XUnit style tests
+
+A number of matcher libraries have been written to augment Go's built-in XUnit style tests.  Here are two that have gained traction:
+
+- [testify](https://github.com/stretchr/testify)
+- [gocheck](http://labix.org/gocheck)
+
+You can also use Ginkgo's matcher library [Gomega](https://github.com/onsi/gomega) in [XUnit style tests](http://onsi.github.io/gomega/#using-gomega-with-golangs-xunitstyle-tests)
+
+### BDD style testing frameworks
+
+There are a handful of BDD-style testing frameworks written for Go.  Here are a few:
+
+- [Ginkgo](https://github.com/onsi/ginkgo) ;)
+- [GoConvey](https://github.com/smartystreets/goconvey) 
+- [Goblin](https://github.com/franela/goblin)
+- [Mao](https://github.com/azer/mao)
+- [Zen](https://github.com/pranavraja/zen)
+
+Finally, @shageman has [put together](https://github.com/shageman/gotestit) a comprehensive comparison of Go testing libraries.
+
+Go explore!

+A Ginkgo release is a tagged git sha and a GitHub release.  To cut a release:
+
+1. Ensure CHANGELOG.md is up to date.
+  - Use `git log --pretty=format:'- %s [%h]' HEAD...vX.X.X` to list all the commits since the last release
+  - Categorize the changes into
+    - Breaking Changes (requires a major version)
+    - New Features (minor version)
+    - Fixes (fix version)
+    - Maintenance (which in general should not be mentioned in `CHANGELOG.md` as they have no user impact)
+1. Update `VERSION` in `config/config.go`
+1. Create a commit with the version number as the commit message (e.g. `v1.3.0`)
+1. Tag the commit with the version number as the tag name (e.g. `v1.3.0`)
+1. Push the commit and tag to GitHub
+1. Create a new [GitHub release](https://help.github.com/articles/creating-releases/) with the version number as the tag  (e.g. `v1.3.0`).  List the key changes in the release notes.

+# go-colorable
+
+Colorable writer for windows.
+
+For example, most of logger packages doesn't show colors on windows. (I know we can do it with ansicon. But I don't want.)
+This package is possible to handle escape sequence for ansi color on windows.
+
+## Too Bad!
+
+![](https://raw.githubusercontent.com/mattn/go-colorable/gh-pages/bad.png)
+
+
+## So Good!
+
+![](https://raw.githubusercontent.com/mattn/go-colorable/gh-pages/good.png)
+
+## Usage
+
+```go
+logrus.SetFormatter(&logrus.TextFormatter{ForceColors: true})
+logrus.SetOutput(colorable.NewColorableStdout())
+
+logrus.Info("succeeded")
+logrus.Warn("not correct")
+logrus.Error("something error")
+logrus.Fatal("panic")
+```
+
+You can compile above code on non-windows OSs.
+
+## Installation
+
+```

+## HEAD
+
+### Features
+- Make string pretty diff user configurable (#273) [eb112ce, 649b44d]
+
+### Fixes
+- Use httputil.DumpRequest to pretty-print unhandled requests (#278) [a4ff0fc, b7d1a52]
+- fix typo floa32 > float32 (#272) [041ae3b, 6e33911]
+- Fix link to documentation on adding your own matchers (#270) [bb2c830, fcebc62]
+- Use setters and getters to avoid race condition (#262) [13057c3, a9c79f1]
+- Avoid sending a signal if the process is not alive (#259) [b8043e5, 4fc1762]
+- Improve message from AssignableToTypeOf when expected value is nil (#281) [9c1fb20]
+
+## 1.3.0
+
+Improvements:
+
+- The `Equal` matcher matches byte slices more performantly.
+- Improved how `MatchError` matches error strings.
+- `MatchXML` ignores the order of xml node attributes.
+- Improve support for XUnit style golang tests. ([#254](https://github.com/onsi/gomega/issues/254))
+
+Bug Fixes:
+
+- Diff generation now handles multi-byte sequences correctly.
+- Multiple goroutines can now call `gexec.Build` concurrently.
+
+## 1.2.0
+
+Improvements:
+
+- Added `BeSent` which attempts to send a value down a channel and fails if the attempt blocks.  Can be paired with `Eventually` to safely send a value down a channel with a timeout.
+- `Ω`, `Expect`, `Eventually`, and `Consistently` now immediately `panic` if there is no registered fail handler.  This is always a mistake that can hide failing tests.
+- `Receive()` no longer errors when passed a closed channel, it's perfectly fine to attempt to read from a closed channel so Ω(c).Should(Receive()) always fails and Ω(c).ShoudlNot(Receive()) always passes with a closed channel.
+- Added `HavePrefix` and `HaveSuffix` matchers.
+- `ghttp` can now handle concurrent requests.
+- Added `Succeed` which allows one to write `Ω(MyFunction()).Should(Succeed())`.
+- Improved `ghttp`'s behavior around failing assertions and panics:
+    - If a registered handler makes a failing assertion `ghttp` will return `500`.
+    - If a registered handler panics, `ghttp` will return `500` *and* fail the test.  This is new behavior that may cause existing code to break.  This code is almost certainly incorrect and creating a false positive.
+- `ghttp` servers can take an `io.Writer`.  `ghttp` will write a line to the writer when each request arrives.
+- Added `WithTransform` matcher to allow munging input data before feeding into the relevant matcher
+- Added boolean `And`, `Or`, and `Not` matchers to allow creating composite matchers
+- Added `gbytes.TimeoutCloser`, `gbytes.TimeoutReader`, and `gbytes.TimeoutWriter` - these are convenience wrappers that timeout if the underlying Closer/Reader/Writer does not return within the alloted time.
+- Added `gbytes.BufferReader` - this constructs a `gbytes.Buffer` that asynchronously reads the passed-in `io.Reader` into its buffer.
+
+Bug Fixes:
+- gexec: `session.Wait` now uses `EventuallyWithOffset` to get the right line number in the failure.
+- `ContainElement` no longer bails if a passed-in matcher errors.
+
+## 1.0 (8/2/2014)
+
+No changes. Dropping "beta" from the version number.
+
+## 1.0.0-beta (7/8/2014)
+Breaking Changes:
+
+- Changed OmegaMatcher interface.  Instead of having `Match` return failure messages, two new methods `FailureMessage` and `NegatedFailureMessage` are called instead.
+- Moved and renamed OmegaFailHandler to types.GomegaFailHandler and OmegaMatcher to types.GomegaMatcher.  Any references to OmegaMatcher in any custom matchers will need to be changed to point to types.GomegaMatcher
+
+New Test-Support Features:
+
+- `ghttp`: supports testing http clients
+    - Provides a flexible fake http server
+    - Provides a collection of chainable http handlers that perform assertions.
+- `gbytes`: supports making ordered assertions against streams of data
+    - Provides a `gbytes.Buffer`
+    - Provides a `Say` matcher to perform ordered assertions against output data
+- `gexec`: supports testing external processes
+    - Provides support for building Go binaries
+    - Wraps and starts `exec.Cmd` commands
+    - Makes it easy to assert against stdout and stderr
+    - Makes it easy to send signals and wait for processes to exit
+    - Provides an `Exit` matcher to assert against exit code.
+
+DSL Changes:
+
+- `Eventually` and `Consistently` can accept `time.Duration` interval and polling inputs.
+- The default timeouts for `Eventually` and `Consistently` are now configurable.
+
+New Matchers:
+
+- `ConsistOf`: order-independent assertion against the elements of an array/slice or keys of a map.
+- `BeTemporally`: like `BeNumerically` but for `time.Time`
+- `HaveKeyWithValue`: asserts a map has a given key with the given value.
+
+Updated Matchers:
+
+- `Receive` matcher can take a matcher as an argument and passes only if the channel under test receives an objet that satisfies the passed-in matcher.
+- Matchers that implement `MatchMayChangeInTheFuture(actual interface{}) bool` can inform `Eventually` and/or `Consistently` when a match has no chance of changing status in the future.  For example, `Receive` returns `false` when a channel is closed.
+
+Misc:
+
+- Start using semantic versioning
+- Start maintaining changelog
+
+Major refactor:
+
+- Pull out Gomega's internal to `internal`

+A Gomega release is a tagged sha and a GitHub release.  To cut a release:
+
+1. Ensure CHANGELOG.md is up to date.
+  - Use `git log --pretty=format:'- %s [%h]' HEAD...vX.X.X` to list all the commits since the last release
+  - Categorize the changes into
+    - Breaking Changes (requires a major version)
+    - New Features (minor version)
+    - Fixes (fix version)
+    - Maintenance (which in general should not be mentioned in `CHANGELOG.md` as they have no user impact)
+2. Update GOMEGA_VERSION in `gomega_dsl.go`
+3. Push a commit with the version number as the commit message (e.g. `v1.3.0`)
+4. Create a new [GitHub release](https://help.github.com/articles/creating-releases/) with the version number as the tag  (e.g. `v1.3.0`).  List the key changes in the release notes.

+# What is diskv?
+
+Diskv (disk-vee) is a simple, persistent key-value store written in the Go
+language. It starts with an incredibly simple API for storing arbitrary data on
+a filesystem by key, and builds several layers of performance-enhancing
+abstraction on top.  The end result is a conceptually simple, but highly
+performant, disk-backed storage system.

+# Installing
+
+Install [Go 1][3], either [from source][4] or [with a prepackaged binary][5].
+Then,
+
+```bash
+$ go get github.com/peterbourgon/diskv
+```
+
+[3]: http://golang.org
+[4]: http://golang.org/doc/install/source
+[5]: http://golang.org/doc/install
+
+
+# Usage
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/peterbourgon/diskv"
+)
+
+func main() {
+	// Simplest transform function: put all the data files into the base dir.
+	flatTransform := func(s string) []string { return []string{} }
+
+	// Initialize a new diskv store, rooted at "my-data-dir", with a 1MB cache.
+	d := diskv.New(diskv.Options{
+		BasePath:     "my-data-dir",
+		Transform:    flatTransform,
+		CacheSizeMax: 1024 * 1024,
+	})
+
+	// Write three bytes to the key "alpha".
+	key := "alpha"
+	d.Write(key, []byte{'1', '2', '3'})
+
+	// Read the value back out of the store.
+	value, _ := d.Read(key)
+	fmt.Printf("%v\n", value)
+
+	// Erase the key+value from the store (and the disk).
+	d.Erase(key)
+}
+```
+
+More complex examples can be found in the "examples" subdirectory.
+
+
+# Theory
+
+## Basic idea
+
+At its core, diskv is a map of a key (`string`) to arbitrary data (`[]byte`).
+The data is written to a single file on disk, with the same name as the key.
+The key determines where that file will be stored, via a user-provided
+`TransformFunc`, which takes a key and returns a slice (`[]string`)
+corresponding to a path list where the key file will be stored. The simplest
+TransformFunc,
+
+```go
+func SimpleTransform (key string) []string {
+    return []string{}
+}
+```
+
+will place all keys in the same, base directory. The design is inspired by
+[Redis diskstore][6]; a TransformFunc which emulates the default diskstore
+behavior is available in the content-addressable-storage example.
+
+[6]: http://groups.google.com/group/redis-db/browse_thread/thread/d444bc786689bde9?pli=1
+
+**Note** that your TransformFunc should ensure that one valid key doesn't
+transform to a subset of another valid key. That is, it shouldn't be possible
+to construct valid keys that resolve to directory names. As a concrete example,
+if your TransformFunc splits on every 3 characters, then
+
+```go
+d.Write("abcabc", val) // OK: written to <base>/abc/abc/abcabc
+d.Write("abc", val)    // Error: attempted write to <base>/abc/abc, but it's a directory
+```
+
+This will be addressed in an upcoming version of diskv.
+
+Probably the most important design principle behind diskv is that your data is
+always flatly available on the disk. diskv will never do anything that would
+prevent you from accessing, copying, backing up, or otherwise interacting with
+your data via common UNIX commandline tools.
+
+## Adding a cache
+
+An in-memory caching layer is provided by combining the BasicStore
+functionality with a simple map structure, and keeping it up-to-date as
+appropriate. Since the map structure in Go is not threadsafe, it's combined
+with a RWMutex to provide safe concurrent access.
+
+## Adding order
+
+diskv is a key-value store and therefore inherently unordered. An ordering
+system can be injected into the store by passing something which satisfies the
+diskv.Index interface. (A default implementation, using Google's
+[btree][7] package, is provided.) Basically, diskv keeps an ordered (by a
+user-provided Less function) index of the keys, which can be queried.
+
+[7]: https://github.com/google/btree
+
+## Adding compression
+
+Something which implements the diskv.Compression interface may be passed
+during store creation, so that all Writes and Reads are filtered through
+a compression/decompression pipeline. Several default implementations,
+using stdlib compression algorithms, are provided. Note that data is cached
+compressed; the cost of decompression is borne with each Read.
+
+## Streaming
+
+diskv also now provides ReadStream and WriteStream methods, to allow very large
+data to be handled efficiently.
+
+
+# Future plans
+
+ * Needs plenty of robust testing: huge datasets, etc...
+ * More thorough benchmarking
+ * Your suggestions for use-cases I haven't thought of

+// Pushgateway (package push).
+//
+// All exported functions and methods are safe to be used concurrently unless
+//specified otherwise.
+//
+// A Basic Example
+//
+// As a starting point, a very basic usage example:
+//
+//    package main
+//
+//    import (
+//    	"net/http"
+//
+//    	"github.com/prometheus/client_golang/prometheus"
+//    	"github.com/prometheus/client_golang/prometheus/promhttp"
+//    )
+//
+//    var (
+//    	cpuTemp = prometheus.NewGauge(prometheus.GaugeOpts{
+//    		Name: "cpu_temperature_celsius",
+//    		Help: "Current temperature of the CPU.",
+//    	})
+//    	hdFailures = prometheus.NewCounterVec(
+//    		prometheus.CounterOpts{
+//    			Name: "hd_errors_total",
+//    			Help: "Number of hard-disk errors.",
+//    		},
+//    		[]string{"device"},
+//    	)
+//    )
+//
+//    func init() {
+//    	// Metrics have to be registered to be exposed:
+//    	prometheus.MustRegister(cpuTemp)
+//    	prometheus.MustRegister(hdFailures)
+//    }
+//
+//    func main() {
+//    	cpuTemp.Set(65.3)
+//    	hdFailures.With(prometheus.Labels{"device":"/dev/sda"}).Inc()
+//
+//    	// The Handler function provides a default handler to expose metrics
+//    	// via an HTTP server. "/metrics" is the usual endpoint for that.
+//    	http.Handle("/metrics", promhttp.Handler())
+//    	http.ListenAndServe(":8080", nil)
+//    }
+//
+//
+// This is a complete program that exports two metrics, a Gauge and a Counter,
+// the latter with a label attached to turn it into a (one-dimensional) vector.
+//
+// Metrics
+//
+// The number of exported identifiers in this package might appear a bit
+// overwhelming. Hovever, in addition to the basic plumbing shown in the example
+// above, you only need to understand the different metric types and their
+// vector versions for basic usage.
+//
+// Above, you have already touched the Counter and the Gauge. There are two more
+// advanced metric types: the Summary and Histogram. A more thorough description
+// of those four metric types can be found in the Prometheus docs:
+// https://prometheus.io/docs/concepts/metric_types/
+//
+// A fifth "type" of metric is Untyped. It behaves like a Gauge, but signals the
+// Prometheus server not to assume anything about its type.
+//
+// In addition to the fundamental metric types Gauge, Counter, Summary,
+// Histogram, and Untyped, a very important part of the Prometheus data model is
+// the partitioning of samples along dimensions called labels, which results in
+// metric vectors. The fundamental types are GaugeVec, CounterVec, SummaryVec,
+// HistogramVec, and UntypedVec.
+//
+// While only the fundamental metric types implement the Metric interface, both
+// the metrics and their vector versions implement the Collector interface. A
+// Collector manages the collection of a number of Metrics, but for convenience,
+// a Metric can also “collect itself”. Note that Gauge, Counter, Summary,
+// Histogram, and Untyped are interfaces themselves while GaugeVec, CounterVec,
+// SummaryVec, HistogramVec, and UntypedVec are not.
+//
+// To create instances of Metrics and their vector versions, you need a suitable
+// …Opts struct, i.e. GaugeOpts, CounterOpts, SummaryOpts,
+// HistogramOpts, or UntypedOpts.
+//
+// Custom Collectors and constant Metrics
+//
+// While you could create your own implementations of Metric, most likely you
+// will only ever implement the Collector interface on your own. At a first
+// glance, a custom Collector seems handy to bundle Metrics for common
+// registration (with the prime example of the different metric vectors above,
+// which bundle all the metrics of the same name but with different labels).
+//
+// There is a more involved use case, too: If you already have metrics
+// available, created outside of the Prometheus context, you don't need the
+// interface of the various Metric types. You essentially want to mirror the
+// existing numbers into Prometheus Metrics during collection. An own
+// implementation of the Collector interface is perfect for that. You can create
+// Metric instances “on the fly” using NewConstMetric, NewConstHistogram, and
+// NewConstSummary (and their respective Must… versions). That will happen in
+// the Collect method. The Describe method has to return separate Desc
+// instances, representative of the “throw-away” metrics to be created
+// later. NewDesc comes in handy to create those Desc instances.
+//
+// The Collector example illustrates the use case. You can also look at the
+// source code of the processCollector (mirroring process metrics), the
+// goCollector (mirroring Go metrics), or the expvarCollector (mirroring expvar
+// metrics) as examples that are used in this package itself.
+//
+// If you just need to call a function to get a single float value to collect as
+// a metric, GaugeFunc, CounterFunc, or UntypedFunc might be interesting
+// shortcuts.
+//
+// Advanced Uses of the Registry
+//
+// While MustRegister is the by far most common way of registering a Collector,
+// sometimes you might want to handle the errors the registration might
+// cause. As suggested by the name, MustRegister panics if an error occurs. With
+// the Register function, the error is returned and can be handled.
+//
+// An error is returned if the registered Collector is incompatible or
+// inconsistent with already registered metrics. The registry aims for
+// consistency of the collected metrics according to the Prometheus data
+// model. Inconsistencies are ideally detected at registration time, not at
+// collect time. The former will usually be detected at start-up time of a
+// program, while the latter will only happen at scrape time, possibly not even
+// on the first scrape if the inconsistency only becomes relevant later. That is
+// the main reason why a Collector and a Metric have to describe themselves to
+// the registry.
+//
+// So far, everything we did operated on the so-called default registry, as it
+// can be found in the global DefaultRegistry variable. With NewRegistry, you
+// can create a custom registry, or you can even implement the Registerer or
+// Gatherer interfaces yourself. The methods Register and Unregister work in
+// the same way on a custom registry as the global functions Register and
+// Unregister on the default registry.
+//
+// There are a number of uses for custom registries: You can use registries
+// with special properties, see NewPedanticRegistry. You can avoid global state,
+// as it is imposed by the DefaultRegistry. You can use multiple registries at
+// the same time to expose different metrics in different ways. You can use
+// separate registries for testing purposes.
+//
+// Also note that the DefaultRegistry comes registered with a Collector for Go
+// runtime metrics (via NewGoCollector) and a Collector for process metrics (via
+// NewProcessCollector). With a custom registry, you are in control and decide
+// yourself about the Collectors to register.
+//
+// HTTP Exposition
+//
+// The Registry implements the Gatherer interface. The caller of the Gather
+// method can then expose the gathered metrics in some way. Usually, the metrics
+// are served via HTTP on the /metrics endpoint. That's happening in the example
+// above. The tools to expose metrics via HTTP are in the promhttp
+// sub-package. (The top-level functions in the prometheus package are
+// deprecated.)
+//
+// Pushing to the Pushgateway
+//
+// Function for pushing to the Pushgateway can be found in the push sub-package.
+//
+// Other Means of Exposition
+//
+// More ways of exposing metrics can easily be added. Sending metrics to
+// Graphite would be an example that will soon be implemented.

+// proxying the expvar value. The type will always be Untyped.

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+   copyright license to reproduce, prepare Derivative Works of,
+   publicly display, publicly perform, sublicense, and distribute the
+   Work and such Derivative Works in Source or Object form.
+
+3. Grant of Patent License. Subject to the terms and conditions of
+   this License, each Contributor hereby grants to You a perpetual,
+   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+   (except as stated in this section) patent license to make, have made,
+   use, offer to sell, sell, import, and otherwise transfer the Work,
+   where such license applies only to those patent claims licensable
+   by such Contributor that are necessarily infringed by their
+   Contribution(s) alone or by combination of their Contribution(s)
+   with the Work to which such Contribution(s) was submitted. If You
+   institute patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Work
+   or a Contribution incorporated within the Work constitutes direct
+   or contributory patent infringement, then any patent licenses
+   granted to You under this License for that Work shall terminate
+   as of the date such litigation is filed.
+
+4. Redistribution. You may reproduce and distribute copies of the
+   Work or Derivative Works thereof in any medium, with or without
+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:
+
+   (a) You must give any other recipients of the Work or
+       Derivative Works a copy of this License; and
+
+   (b) You must cause any modified files to carry prominent notices
+       stating that You changed the files; and
+
+   (c) You must retain, in the Source form of any Derivative Works
+       that You distribute, all copyright, patent, trademark, and
+       attribution notices from the Source form of the Work,
+       excluding those notices that do not pertain to any part of
+       the Derivative Works; and
+
+   (d) If the Work includes a "NOTICE" text file as part of its
+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not
+       pertain to any part of the Derivative Works, in at least one
+       of the following places: within a NOTICE text file distributed
+       as part of the Derivative Works; within the Source form or
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution
+       notices within Derivative Works that You distribute, alongside
+       or as an addendum to the NOTICE text from the Work, provided
+       that such additional attribution notices cannot be construed
+       as modifying the License.
+
+   You may add Your own copyright statement to Your modifications and
+   may provide additional or different license terms and conditions
+   for use, reproduction, or distribution of Your modifications, or
+   for any such Derivative Works as a whole, provided Your use,
+   reproduction, and distribution of the Work otherwise complies with
+   the conditions stated in this License.
+
+5. Submission of Contributions. Unless You explicitly state otherwise,
+   any Contribution intentionally submitted for inclusion in the Work
+   by You to the Licensor shall be under the terms and conditions of
+   this License, without any additional terms or conditions.
+   Notwithstanding the above, nothing herein shall supersede or modify
+   the terms of any separate license agreement you may have executed
+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or
+   agreed to in writing, Licensor provides the Work (and each
+   Contributor provides its Contributions) on an "AS IS" BASIS,
+   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+   implied, including, without limitation, any warranties or conditions
+   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+   whether in tort (including negligence), contract, or otherwise,
+   unless required by applicable law (such as deliberate and grossly
+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the
+   Work (including but not limited to damages for loss of goodwill,
+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+* If you have a trivial fix or improvement, go ahead and create a pull request,
+  addressing (with `@...`) the maintainer of this repository (see
+  [MAINTAINERS.md](MAINTAINERS.md)) in the description of the pull request.
+
+* If you plan to do something more involved, first discuss your ideas
+  on our [mailing list](https://groups.google.com/forum/?fromgroups#!forum/prometheus-developers).
+  This will avoid unnecessary work and surely give you and us a good deal

+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+# Overview
+
+Cobra is a library providing a simple interface to create powerful modern CLI
+interfaces similar to git & go tools.
+
+Cobra is also an application that will generate your application scaffolding to rapidly
+develop a Cobra-based application.
+
+Cobra provides:
+* Easy subcommand-based CLIs: `app server`, `app fetch`, etc.
+* Fully POSIX-compliant flags (including short & long versions)
+* Nested subcommands
+* Global, local and cascading flags
+* Easy generation of applications & commands with `cobra init appname` & `cobra add cmdname`
+* Intelligent suggestions (`app srver`... did you mean `app server`?)
+* Automatic help generation for commands and flags
+* Automatic help flag recognition of `-h`, `--help`, etc.
+* Automatically generated bash autocomplete for your application
+* Automatically generated man pages for your application
+* Command aliases so you can change things without breaking them
+* The flexibility to define your own help, usage, etc.
+* Optional tight integration with [viper](http://github.com/spf13/viper) for 12-factor apps
+
+# Concepts
+
+Cobra is built on a structure of commands, arguments & flags.
+
+**Commands** represent actions, **Args** are things and **Flags** are modifiers for those actions.
+
+The best applications will read like sentences when used. Users will know how
+to use the application because they will natively understand how to use it.
+
+The pattern to follow is
+`APPNAME VERB NOUN --ADJECTIVE.`
+    or
+`APPNAME COMMAND ARG --FLAG`
+
+A few good real world examples may better illustrate this point.
+
+In the following example, 'server' is a command, and 'port' is a flag:
+
+    hugo server --port=1313
+
+In this command we are telling Git to clone the url bare.
+
+    git clone URL --bare
+
+## Commands
+
+Command is the central point of the application. Each interaction that
+the application supports will be contained in a Command. A command can
+have children commands and optionally run an action.
+
+In the example above, 'server' is the command.
+
+[More about cobra.Command](https://godoc.org/github.com/spf13/cobra#Command)
+
+## Flags
+
+A flag is a way to modify the behavior of a command. Cobra supports
+fully POSIX-compliant flags as well as the Go [flag package](https://golang.org/pkg/flag/).
+A Cobra command can define flags that persist through to children commands
+and flags that are only available to that command.
+
+In the example above, 'port' is the flag.
+
+Flag functionality is provided by the [pflag
+library](https://github.com/spf13/pflag), a fork of the flag standard library
+which maintains the same interface while adding POSIX compliance.
+
+# Installing
+Using Cobra is easy. First, use `go get` to install the latest version
+of the library. This command will install the `cobra` generator executable
+along with the library and its dependencies:
+
+    go get -u github.com/spf13/cobra/cobra
+
+Next, include Cobra in your application:
+
+```go
+import "github.com/spf13/cobra"
+```
+
+# Getting Started
+
+While you are welcome to provide your own organization, typically a Cobra-based
+application will follow the following organizational structure:
+
+```
+  ▾ appName/
+    ▾ cmd/
+        add.go
+        your.go
+        commands.go
+        here.go
+      main.go
+```
+
+In a Cobra app, typically the main.go file is very bare. It serves one purpose: initializing Cobra.
+
+```go
+package main
+
+import (
+  "fmt"
+  "os"
+
+  "{pathToYourApp}/cmd"
+)
+
+func main() {
+  cmd.Execute()
+}
+```
+
+## Using the Cobra Generator
+
+Cobra provides its own program that will create your application and add any
+commands you want. It's the easiest way to incorporate Cobra into your application.
+
+[Here](https://github.com/spf13/cobra/blob/master/cobra/README.md) you can find more information about it.
+
+## Using the Cobra Library
+
+To manually implement Cobra you need to create a bare main.go file and a rootCmd file.
+You will optionally provide additional commands as you see fit.
+
+### Create rootCmd
+
+Cobra doesn't require any special constructors. Simply create your commands.
+
+Ideally you place this in app/cmd/root.go:
+
+```go
+var rootCmd = &cobra.Command{
+  Use:   "hugo",
+  Short: "Hugo is a very fast static site generator",
+  Long: `A Fast and Flexible Static Site Generator built with
+                love by spf13 and friends in Go.
+                Complete documentation is available at http://hugo.spf13.com`,
+  Run: func(cmd *cobra.Command, args []string) {
+    // Do Stuff Here
+  },
+}
+
+func Execute() {
+  if err := rootCmd.Execute(); err != nil {
+    fmt.Println(err)
+    os.Exit(1)
+  }
+}
+```
+
+You will additionally define flags and handle configuration in your init() function.
+
+For example cmd/root.go:
+
+```go
+import (
+  "fmt"
+  "os"
+
+  homedir "github.com/mitchellh/go-homedir"
+  "github.com/spf13/cobra"
+  "github.com/spf13/viper"
+)
+
+func init() {

+
+### Create your main.go
+
+With the root command you need to have your main function execute it.
+Execute should be run on the root for clarity, though it can be called on any command.
+
+In a Cobra app, typically the main.go file is very bare. It serves, one purpose, to initialize Cobra.
+
+```go
+package main
+
+import (
+  "fmt"
+  "os"
+
+  "{pathToYourApp}/cmd"
+)
+
+func main() {
+  cmd.Execute()
+}
+```
+
+### Create additional commands
+
+Additional commands can be defined and typically are each given their own file
+inside of the cmd/ directory.
+
+If you wanted to create a version command you would create cmd/version.go and
+populate it with the following:
+
+```go
+package cmd
+
+import (
+  "fmt"
+
+  "github.com/spf13/cobra"
+)
+
+func init() {
+  rootCmd.AddCommand(versionCmd)
+}
+
+var versionCmd = &cobra.Command{
+  Use:   "version",
+  Short: "Print the version number of Hugo",
+  Long:  `All software has versions. This is Hugo's`,
+  Run: func(cmd *cobra.Command, args []string) {
+    fmt.Println("Hugo Static Site Generator v0.9 -- HEAD")
+  },
+}
+```
+
+## Working with Flags
+
+Flags provide modifiers to control how the action command operates.
+
+### Assign flags to a command
+
+Since the flags are defined and used in different locations, we need to
+define a variable outside with the correct scope to assign the flag to
+work with.
+
+```go
+var Verbose bool
+var Source string
+```
+
+There are two different approaches to assign a flag.
+
+### Persistent Flags
+
+A flag can be 'persistent' meaning that this flag will be available to the
+command it's assigned to as well as every command under that command. For
+global flags, assign a flag as a persistent flag on the root.
+
+```go
+rootCmd.PersistentFlags().BoolVarP(&Verbose, "verbose", "v", false, "verbose output")
+```
+
+### Local Flags
+
+A flag can also be assigned locally which will only apply to that specific command.
+
+```go
+rootCmd.Flags().StringVarP(&Source, "source", "s", "", "Source directory to read from")
+```
+
+### Local Flag on Parent Commands
+
+By default Cobra only parses local flags on the target command, any local flags on
+parent commands are ignored. By enabling `Command.TraverseChildren` Cobra will
+parse local flags on each command before executing the target command.
+
+```go
+command := cobra.Command{
+  Use: "print [OPTIONS] [COMMANDS]",
+  TraverseChildren: true,
+}
+```
+
+### Bind Flags with Config
+
+You can also bind your flags with [viper](https://github.com/spf13/viper):
+```go
+var author string
+
+func init() {
+  rootCmd.PersistentFlags().StringVar(&author, "author", "YOUR NAME", "Author name for copyright attribution")
+  viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author"))
+}
+```
+
+In this example the persistent flag `author` is bound with `viper`.
+**Note**, that the variable `author` will not be set to the value from config,
+when the `--author` flag is not provided by user.
+
+More in [viper documentation](https://github.com/spf13/viper#working-with-flags).
+
+### Required flags
+
+Flags are optional by default. If instead you wish your command to report an error
+when a flag has not been set, mark it as required:
+```go
+rootCmd.Flags().StringVarP(&Region, "region", "r", "", "AWS region (required)")
+rootCmd.MarkFlagRequired("region")
+```
+
+## Positional and Custom Arguments
+
+Validation of positional arguments can be specified using the `Args` field
+of `Command`.
+
+The following validators are built in:
+
+- `NoArgs` - the command will report an error if there are any positional args.
+- `ArbitraryArgs` - the command will accept any args.
+- `OnlyValidArgs` - the command will report an error if there are any positional args that are not in the `ValidArgs` field of `Command`.
+- `MinimumNArgs(int)` - the command will report an error if there are not at least N positional args.
+- `MaximumNArgs(int)` - the command will report an error if there are more than N positional args.
+- `ExactArgs(int)` - the command will report an error if there are not exactly N positional args.
+- `RangeArgs(min, max)` - the command will report an error if the number of args is not between the minimum and maximum number of expected args.
+
+An example of setting the custom validator:
+
+```go
+var cmd = &cobra.Command{
+  Short: "hello",
+  Args: func(cmd *cobra.Command, args []string) error {
+    if len(args) < 1 {
+      return errors.New("requires at least one arg")
+    }
+    if myapp.IsValidColor(args[0]) {
+      return nil
+    }
+    return fmt.Errorf("invalid color specified: %s", args[0])
+  },
+  Run: func(cmd *cobra.Command, args []string) {
+    fmt.Println("Hello, World!")
+  },
+}
+```
+
+## Example
+
+In the example below, we have defined three commands. Two are at the top level
+and one (cmdTimes) is a child of one of the top commands. In this case the root
+is not executable meaning that a subcommand is required. This is accomplished
+by not providing a 'Run' for the 'rootCmd'.
+
+We have only defined one flag for a single command.
+
+More documentation about flags is available at https://github.com/spf13/pflag
+
+```go
+package main
+
+import (
+  "fmt"
+  "strings"
+
+  "github.com/spf13/cobra"
+)
+
+func main() {
+  var echoTimes int
+
+  var cmdPrint = &cobra.Command{
+    Use:   "print [string to print]",
+    Short: "Print anything to the screen",
+    Long: `print is for printing anything back to the screen.
+For many years people have printed back to the screen.`,
+    Args: cobra.MinimumNArgs(1),
+    Run: func(cmd *cobra.Command, args []string) {
+      fmt.Println("Print: " + strings.Join(args, " "))
+    },
+  }
+
+  var cmdEcho = &cobra.Command{
+    Use:   "echo [string to echo]",
+    Short: "Echo anything to the screen",
+    Long: `echo is for echoing anything back.
+Echo works a lot like print, except it has a child command.`,
+    Args: cobra.MinimumNArgs(1),
+    Run: func(cmd *cobra.Command, args []string) {
+      fmt.Println("Print: " + strings.Join(args, " "))
+    },
+  }
+
+  var cmdTimes = &cobra.Command{
+    Use:   "times [# times] [string to echo]",
+    Short: "Echo anything to the screen more times",
+    Long: `echo things multiple times back to the user by providing
+a count and a string.`,
+    Args: cobra.MinimumNArgs(1),
+    Run: func(cmd *cobra.Command, args []string) {
+      for i := 0; i < echoTimes; i++ {
+        fmt.Println("Echo: " + strings.Join(args, " "))
+      }
+    },
+  }
+
+  cmdTimes.Flags().IntVarP(&echoTimes, "times", "t", 1, "times to echo the input")
+
+  var rootCmd = &cobra.Command{Use: "app"}
+  rootCmd.AddCommand(cmdPrint, cmdEcho)
+  cmdEcho.AddCommand(cmdTimes)
+  rootCmd.Execute()
+}
+```

+
+## Help Command
+
+Cobra automatically adds a help command to your application when you have subcommands.
+This will be called when a user runs 'app help'. Additionally, help will also
+support all other commands as input. Say, for instance, you have a command called
+'create' without any additional configuration; Cobra will work when 'app help
+create' is called.  Every command will automatically have the '--help' flag added.
+
+### Example
+
+The following output is automatically generated by Cobra. Nothing beyond the
+command and flag definitions are needed.
+
+    $ cobra help
+
+    Cobra is a CLI library for Go that empowers applications.
+    This application is a tool to generate the needed files
+    to quickly create a Cobra application.
+
+    Usage:
+      cobra [command]
+
+    Available Commands:
+      add         Add a command to a Cobra Application
+      help        Help about any command
+      init        Initialize a Cobra Application
+
+    Flags:
+      -a, --author string    author name for copyright attribution (default "YOUR NAME")
+          --config string    config file (default is $HOME/.cobra.yaml)
+      -h, --help             help for cobra
+      -l, --license string   name of license for the project
+          --viper            use Viper for configuration (default true)
+
+    Use "cobra [command] --help" for more information about a command.
+
+
+Help is just a command like any other. There is no special logic or behavior
+around it. In fact, you can provide your own if you want.
+
+### Defining your own help
+
+You can provide your own Help command or your own template for the default command to use
+with following functions:
+
+```go
+cmd.SetHelpCommand(cmd *Command)
+cmd.SetHelpFunc(f func(*Command, []string))
+cmd.SetHelpTemplate(s string)
+```
+
+The latter two will also apply to any children commands.
+
+## Usage Message
+
+When the user provides an invalid flag or invalid command, Cobra responds by
+showing the user the 'usage'.
+
+### Example
+You may recognize this from the help above. That's because the default help
+embeds the usage as part of its output.
+
+    $ cobra --invalid
+    Error: unknown flag: --invalid
+    Usage:
+      cobra [command]
+
+    Available Commands:
+      add         Add a command to a Cobra Application
+      help        Help about any command
+      init        Initialize a Cobra Application
+
+    Flags:
+      -a, --author string    author name for copyright attribution (default "YOUR NAME")
+          --config string    config file (default is $HOME/.cobra.yaml)
+      -h, --help             help for cobra
+      -l, --license string   name of license for the project
+          --viper            use Viper for configuration (default true)
+
+    Use "cobra [command] --help" for more information about a command.
+
+### Defining your own usage
+You can provide your own usage function or template for Cobra to use.
+Like help, the function and template are overridable through public methods:
+
+```go
+cmd.SetUsageFunc(f func(*Command) error)
+cmd.SetUsageTemplate(s string)
+```
+
+## Version Flag
+
+Cobra adds a top-level '--version' flag if the Version field is set on the root command.
+Running an application with the '--version' flag will print the version to stdout using
+the version template. The template can be customized using the
+`cmd.SetVersionTemplate(s string)` function.
+
+## PreRun and PostRun Hooks
+
+It is possible to run functions before or after the main `Run` function of your command. The `PersistentPreRun` and `PreRun` functions will be executed before `Run`. `PersistentPostRun` and `PostRun` will be executed after `Run`.  The `Persistent*Run` functions will be inherited by children if they do not declare their own.  These functions are run in the following order:
+
+- `PersistentPreRun`
+- `PreRun`
+- `Run`
+- `PostRun`
+- `PersistentPostRun`
+
+An example of two commands which use all of these features is below.  When the subcommand is executed, it will run the root command's `PersistentPreRun` but not the root command's `PersistentPostRun`:
+
+```go
+package main
+
+import (
+  "fmt"
+
+  "github.com/spf13/cobra"
+)
+
+func main() {
+
+  var rootCmd = &cobra.Command{
+    Use:   "root [sub]",
+    Short: "My root command",
+    PersistentPreRun: func(cmd *cobra.Command, args []string) {
+      fmt.Printf("Inside rootCmd PersistentPreRun with args: %v\n", args)
+    },
+    PreRun: func(cmd *cobra.Command, args []string) {
+      fmt.Printf("Inside rootCmd PreRun with args: %v\n", args)
+    },
+    Run: func(cmd *cobra.Command, args []string) {
+      fmt.Printf("Inside rootCmd Run with args: %v\n", args)
+    },
+    PostRun: func(cmd *cobra.Command, args []string) {
+      fmt.Printf("Inside rootCmd PostRun with args: %v\n", args)
+    },
+    PersistentPostRun: func(cmd *cobra.Command, args []string) {
+      fmt.Printf("Inside rootCmd PersistentPostRun with args: %v\n", args)
+    },
+  }
+
+  var subCmd = &cobra.Command{
+    Use:   "sub [no options!]",
+    Short: "My subcommand",
+    PreRun: func(cmd *cobra.Command, args []string) {
+      fmt.Printf("Inside subCmd PreRun with args: %v\n", args)
+    },
+    Run: func(cmd *cobra.Command, args []string) {
+      fmt.Printf("Inside subCmd Run with args: %v\n", args)
+    },
+    PostRun: func(cmd *cobra.Command, args []string) {
+      fmt.Printf("Inside subCmd PostRun with args: %v\n", args)
+    },
+    PersistentPostRun: func(cmd *cobra.Command, args []string) {
+      fmt.Printf("Inside subCmd PersistentPostRun with args: %v\n", args)
+    },
+  }
+
+  rootCmd.AddCommand(subCmd)
+
+  rootCmd.SetArgs([]string{""})
+  rootCmd.Execute()
+  fmt.Println()
+  rootCmd.SetArgs([]string{"sub", "arg1", "arg2"})
+  rootCmd.Execute()
+}
+```
+
+Output:
+```
+Inside rootCmd PersistentPreRun with args: []
+Inside rootCmd PreRun with args: []
+Inside rootCmd Run with args: []
+Inside rootCmd PostRun with args: []
+Inside rootCmd PersistentPostRun with args: []
+
+Inside rootCmd PersistentPreRun with args: [arg1 arg2]
+Inside subCmd PreRun with args: [arg1 arg2]
+Inside subCmd Run with args: [arg1 arg2]
+Inside subCmd PostRun with args: [arg1 arg2]
+Inside subCmd PersistentPostRun with args: [arg1 arg2]
+```
+
+## Suggestions when "unknown command" happens
+
+Cobra will print automatic suggestions when "unknown command" errors happen. This allows Cobra to behave similarly to the `git` command when a typo happens. For example:
+
+```
+$ hugo srever
+Error: unknown command "srever" for "hugo"
+
+Did you mean this?
+        server
+
+Run 'hugo --help' for usage.
+```
+
+Suggestions are automatic based on every subcommand registered and use an implementation of [Levenshtein distance](http://en.wikipedia.org/wiki/Levenshtein_distance). Every registered command that matches a minimum distance of 2 (ignoring case) will be displayed as a suggestion.
+
+If you need to disable suggestions or tweak the string distance in your command, use:
+
+```go
+command.DisableSuggestions = true
+```
+
+or
+
+```go
+command.SuggestionsMinimumDistance = 1
+```
+
+You can also explicitly set names for which a given command will be suggested using the `SuggestFor` attribute. This allows suggestions for strings that are not close in terms of string distance, but makes sense in your set of commands and for some which you don't want aliases. Example:
+
+```
+$ kubectl remove
+Error: unknown command "remove" for "kubectl"
+
+Did you mean this?
+        delete
+
+Run 'kubectl help' for usage.
+```
+
+## Generating documentation for your command
+
+Cobra can generate documentation based on subcommands, flags, etc. in the following formats:
+
+- [Markdown](doc/md_docs.md)
+- [ReStructured Text](doc/rest_docs.md)
+- [Man Page](doc/man_docs.md)
+
+## Generating bash completions
+
+Cobra can generate a bash-completion file. If you add more information to your command, these completions can be amazingly powerful and flexible.  Read more about it in [Bash Completions](bash_completions.md).

+# Generating Bash Completions For Your Own cobra.Command
+
+Generating bash completions from a cobra command is incredibly easy. An actual program which does so for the kubernetes kubectl binary is as follows:
+
+```go
+package main
+
+import (
+	"io/ioutil"
+	"os"
+
+	"k8s.io/kubernetes/pkg/kubectl/cmd"
+	"k8s.io/kubernetes/pkg/kubectl/cmd/util"
+)
+
+func main() {
+	kubectl := cmd.NewKubectlCommand(util.NewFactory(nil), os.Stdin, ioutil.Discard, ioutil.Discard)
+	kubectl.GenBashCompletionFile("out.sh")
+}
+```
+
+`out.sh` will get you completions of subcommands and flags. Copy it to `/etc/bash_completion.d/` as described [here](https://debian-administration.org/article/316/An_introduction_to_bash_completion_part_1) and reset your terminal to use autocompletion. If you make additional annotations to your code, you can get even more intelligent and flexible behavior.
+
+## Creating your own custom functions
+
+Some more actual code that works in kubernetes:
+
+```bash
+const (
+        bash_completion_func = `__kubectl_parse_get()
+{
+    local kubectl_output out
+    if kubectl_output=$(kubectl get --no-headers "$1" 2>/dev/null); then
+        out=($(echo "${kubectl_output}" | awk '{print $1}'))
+        COMPREPLY=( $( compgen -W "${out[*]}" -- "$cur" ) )
+    fi
+}
+
+__kubectl_get_resource()
+{
+    if [[ ${#nouns[@]} -eq 0 ]]; then
+        return 1
+    fi
+    __kubectl_parse_get ${nouns[${#nouns[@]} -1]}
+    if [[ $? -eq 0 ]]; then
+        return 0
+    fi
+}
+
+__custom_func() {
+    case ${last_command} in
+        kubectl_get | kubectl_describe | kubectl_delete | kubectl_stop)
+            __kubectl_get_resource
+            return
+            ;;
+        *)
+            ;;
+    esac
+}
+`)
+```
+
+And then I set that in my command definition:
+
+```go
+cmds := &cobra.Command{
+	Use:   "kubectl",
+	Short: "kubectl controls the Kubernetes cluster manager",
+	Long: `kubectl controls the Kubernetes cluster manager.
+
+Find more information at https://github.com/GoogleCloudPlatform/kubernetes.`,
+	Run: runHelp,
+	BashCompletionFunction: bash_completion_func,
+}
+```
+
+The `BashCompletionFunction` option is really only valid/useful on the root command. Doing the above will cause `__custom_func()` to be called when the built in processor was unable to find a solution. In the case of kubernetes a valid command might look something like `kubectl get pod [mypod]`. If you type `kubectl get pod [tab][tab]` the `__customc_func()` will run because the cobra.Command only understood "kubectl" and "get." `__custom_func()` will see that the cobra.Command is "kubectl_get" and will thus call another helper `__kubectl_get_resource()`.  `__kubectl_get_resource` will look at the 'nouns' collected. In our example the only noun will be `pod`.  So it will call `__kubectl_parse_get pod`.  `__kubectl_parse_get` will actually call out to kubernetes and get any pods.  It will then set `COMPREPLY` to valid pods!
+
+## Have the completions code complete your 'nouns'
+
+In the above example "pod" was assumed to already be typed. But if you want `kubectl get [tab][tab]` to show a list of valid "nouns" you have to set them. Simplified code from `kubectl get` looks like:
+
+```go
+validArgs []string = { "pod", "node", "service", "replicationcontroller" }
+
+cmd := &cobra.Command{
+	Use:     "get [(-o|--output=)json|yaml|template|...] (RESOURCE [NAME] | RESOURCE/NAME ...)",
+	Short:   "Display one or many resources",
+	Long:    get_long,
+	Example: get_example,
+	Run: func(cmd *cobra.Command, args []string) {
+		err := RunGet(f, out, cmd, args)
+		util.CheckErr(err)
+	},
+	ValidArgs: validArgs,
+}
+```
+
+Notice we put the "ValidArgs" on the "get" subcommand. Doing so will give results like
+
+```bash
+# kubectl get [tab][tab]
+node                 pod                    replicationcontroller  service
+```
+
+## Plural form and shortcuts for nouns
+
+If your nouns have a number of aliases, you can define them alongside `ValidArgs` using `ArgAliases`:
+
+```go
+argAliases []string = { "pods", "nodes", "services", "svc", "replicationcontrollers", "rc" }
+
+cmd := &cobra.Command{
+    ...
+	ValidArgs:  validArgs,
+	ArgAliases: argAliases
+}
+```
+
+The aliases are not shown to the user on tab completion, but they are accepted as valid nouns by
+the completion algorithm if entered manually, e.g. in:
+
+```bash
+# kubectl get rc [tab][tab]
+backend        frontend       database 
+```
+
+Note that without declaring `rc` as an alias, the completion algorithm would show the list of nouns
+in this example again instead of the replication controllers.
+
+## Mark flags as required
+
+Most of the time completions will only show subcommands. But if a flag is required to make a subcommand work, you probably want it to show up when the user types [tab][tab].  Marking a flag as 'Required' is incredibly easy.
+
+```go
+cmd.MarkFlagRequired("pod")
+cmd.MarkFlagRequired("container")
+```
+
+and you'll get something like
+
+```bash
+# kubectl exec [tab][tab][tab]
+-c            --container=  -p            --pod=  
+```
+
+# Specify valid filename extensions for flags that take a filename
+
+In this example we use --filename= and expect to get a json or yaml file as the argument. To make this easier we annotate the --filename flag with valid filename extensions.
+
+```go
+	annotations := []string{"json", "yaml", "yml"}
+	annotation := make(map[string][]string)
+	annotation[cobra.BashCompFilenameExt] = annotations
+
+	flag := &pflag.Flag{
+		Name:        "filename",
+		Shorthand:   "f",
+		Usage:       usage,
+		Value:       value,
+		DefValue:    value.String(),
+		Annotations: annotation,
+	}
+	cmd.Flags().AddFlag(flag)
+```
+
+Now when you run a command with this filename flag you'll get something like
+
+```bash
+# kubectl create -f 
+test/                         example/                      rpmbuild/
+hello.yml                     test.json
+```
+
+So while there are many other files in the CWD it only shows me subdirs and those with valid extensions.
+
+# Specify custom flag completion
+
+Similar to the filename completion and filtering using cobra.BashCompFilenameExt, you can specify
+a custom flag completion function with cobra.BashCompCustom:
+
+```go
+	annotation := make(map[string][]string)
+	annotation[cobra.BashCompCustom] = []string{"__kubectl_get_namespaces"}
+
+	flag := &pflag.Flag{
+		Name:        "namespace",
+		Usage:       usage,
+		Annotations: annotation,
+	}
+	cmd.Flags().AddFlag(flag)
+```
+
+In addition add the `__handle_namespace_flag` implementation in the `BashCompletionFunction`
+value, e.g.:
+
+```bash
+__kubectl_get_namespaces()
+{
+    local template
+    template="{{ range .items  }}{{ .metadata.name }} {{ end }}"
+    local kubectl_out
+    if kubectl_out=$(kubectl get -o template --template="${template}" namespace 2>/dev/null); then
+        COMPREPLY=( $( compgen -W "${kubectl_out}[*]" -- "$cur" ) )
+    fi
+}
+```
+# Using bash aliases for commands
+
+You can also configure the `bash aliases` for the commands and they will also support completions.
+
+```bash
+alias aliasname=origcommand
+complete -o default -F __start_origcommand aliasname
+
+# and now when you run `aliasname` completion will make
+# suggestions as it did for `origcommand`.
+
+$) aliasname <tab><tab>
+completion     firstcommand   secondcommand
+```

+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<http://www.gnu.org/licenses/>.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type 'show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type 'show c' for details.
+
+The hypothetical commands 'show w' and 'show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than 'show w' and 'show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  'Gnomovision' (which makes passes at compilers) written by James Hacker.

+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type 'show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type 'show c' for details.
+
+The hypothetical commands 'show w' and 'show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.`,

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+
+## Description
+
+pflag is a drop-in replacement for Go's flag package, implementing
+POSIX/GNU-style --flags.
+
+pflag is compatible with the [GNU extensions to the POSIX recommendations
+for command-line options][1]. For a more precise description, see the
+"Command-line flag syntax" section below.
+
+[1]: http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
+
+pflag is available under the same style of BSD license as the Go language,
+which can be found in the LICENSE file.
+
+## Installation
+
+pflag is available using the standard `go get` command.
+
+Install by running:
+
+    go get github.com/spf13/pflag
+
+Run tests by running:
+
+    go test github.com/spf13/pflag
+
+## Usage
+
+pflag is a drop-in replacement of Go's native flag package. If you import
+pflag under the name "flag" then all code should continue to function
+with no changes.
+
+``` go
+import flag "github.com/spf13/pflag"
+```
+
+There is one exception to this: if you directly instantiate the Flag struct
+there is one more field "Shorthand" that you will need to set.
+Most code never instantiates this struct directly, and instead uses
+functions such as String(), BoolVar(), and Var(), and is therefore
+unaffected.
+
+Define flags using flag.String(), Bool(), Int(), etc.
+
+This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
+
+``` go
+var ip *int = flag.Int("flagname", 1234, "help message for flagname")
+```
+
+If you like, you can bind the flag to a variable using the Var() functions.
+
+``` go
+var flagvar int
+func init() {
+    flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
+}
+```
+
+Or you can create custom flags that satisfy the Value interface (with
+pointer receivers) and couple them to flag parsing by
+
+``` go
+flag.Var(&flagVal, "name", "help message for flagname")
+```
+
+For such flags, the default value is just the initial value of the variable.
+
+After all flags are defined, call
+
+``` go
+flag.Parse()
+```
+
+to parse the command line into the defined flags.
+
+Flags may then be used directly. If you're using the flags themselves,
+they are all pointers; if you bind to variables, they're values.
+
+``` go
+fmt.Println("ip has value ", *ip)
+fmt.Println("flagvar has value ", flagvar)
+```
+
+There are helpers function to get values later if you have the FlagSet but
+it was difficult to keep up with all of the flag pointers in your code.
+If you have a pflag.FlagSet with a flag called 'flagname' of type int you
+can use GetInt() to get the int value. But notice that 'flagname' must exist
+and it must be an int. GetString("flagname") will fail.
+
+``` go
+i, err := flagset.GetInt("flagname")
+```
+
+After parsing, the arguments after the flag are available as the
+slice flag.Args() or individually as flag.Arg(i).
+The arguments are indexed from 0 through flag.NArg()-1.
+
+The pflag package also defines some new functions that are not in flag,
+that give one-letter shorthands for flags. You can use these by appending
+'P' to the name of any function that defines a flag.
+
+``` go
+var ip = flag.IntP("flagname", "f", 1234, "help message")
+var flagvar bool
+func init() {
+	flag.BoolVarP(&flagvar, "boolname", "b", true, "help message")
+}
+flag.VarP(&flagVal, "varname", "v", "help message")
+```
+
+Shorthand letters can be used with single dashes on the command line.
+Boolean shorthand flags can be combined with other shorthand flags.
+
+The default set of command-line flags is controlled by
+top-level functions.  The FlagSet type allows one to define
+independent sets of flags, such as to implement subcommands
+in a command-line interface. The methods of FlagSet are
+analogous to the top-level functions for the command-line
+flag set.
+
+## Setting no option default values for flags
+
+After you create a flag it is possible to set the pflag.NoOptDefVal for
+the given flag. Doing this changes the meaning of the flag slightly. If
+a flag has a NoOptDefVal and the flag is set on the command line without
+an option the flag will be set to the NoOptDefVal. For example given:
+
+``` go
+var ip = flag.IntP("flagname", "f", 1234, "help message")
+flag.Lookup("flagname").NoOptDefVal = "4321"
+```
+
+Would result in something like
+
+| Parsed Arguments | Resulting Value |
+| -------------    | -------------   |
+| --flagname=1357  | ip=1357         |
+| --flagname       | ip=4321         |
+| [nothing]        | ip=1234         |
+
+## Command line flag syntax
+
+```
+--flag    // boolean flags, or flags with no option default values
+--flag x  // only on flags without a default value
+--flag=x
+```
+
+Unlike the flag package, a single dash before an option means something
+different than a double dash. Single dashes signify a series of shorthand
+letters for flags. All but the last shorthand letter must be boolean flags
+or a flag with a default value
+
+```
+// boolean or flags where the 'no option default value' is set
+-f
+-f=true
+-abc
+but
+-b true is INVALID
+
+// non-boolean and flags without a 'no option default value'
+-n 1234
+-n=1234
+-n1234
+
+// mixed
+-abcs "hello"
+-absd="hello"
+-abcs1234
+```
+
+Flag parsing stops after the terminator "--". Unlike the flag package,
+flags can be interspersed with arguments anywhere on the command line
+before this terminator.
+
+Integer flags accept 1234, 0664, 0x1234 and may be negative.
+Boolean flags (in their long form) accept 1, 0, t, f, true, false,
+TRUE, FALSE, True, False.
+Duration flags accept any input valid for time.ParseDuration.
+
+## Mutating or "Normalizing" Flag names
+
+It is possible to set a custom flag name 'normalization function.' It allows flag names to be mutated both when created in the code and when used on the command line to some 'normalized' form. The 'normalized' form is used for comparison. Two examples of using the custom normalization func follow.
+
+**Example #1**: You want -, _, and . in flags to compare the same. aka --my-flag == --my_flag == --my.flag
+
+``` go
+func wordSepNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
+	from := []string{"-", "_"}
+	to := "."
+	for _, sep := range from {
+		name = strings.Replace(name, sep, to, -1)
+	}
+	return pflag.NormalizedName(name)
+}
+
+myFlagSet.SetNormalizeFunc(wordSepNormalizeFunc)
+```
+
+**Example #2**: You want to alias two flags. aka --old-flag-name == --new-flag-name
+
+``` go
+func aliasNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
+	switch name {
+	case "old-flag-name":
+		name = "new-flag-name"
+		break
+	}
+	return pflag.NormalizedName(name)
+}
+
+myFlagSet.SetNormalizeFunc(aliasNormalizeFunc)
+```
+
+## Deprecating a flag or its shorthand
+It is possible to deprecate a flag, or just its shorthand. Deprecating a flag/shorthand hides it from help text and prints a usage message when the deprecated flag/shorthand is used.
+
+**Example #1**: You want to deprecate a flag named "badflag" as well as inform the users what flag they should use instead.
+```go
+// deprecate a flag by specifying its name and a usage message
+flags.MarkDeprecated("badflag", "please use --good-flag instead")
+```
+This hides "badflag" from help text, and prints `Flag --badflag has been deprecated, please use --good-flag instead` when "badflag" is used.
+
+**Example #2**: You want to keep a flag name "noshorthandflag" but deprecate its shortname "n".
+```go
+// deprecate a flag shorthand by specifying its flag name and a usage message
+flags.MarkShorthandDeprecated("noshorthandflag", "please use --noshorthandflag only")
+```
+This hides the shortname "n" from help text, and prints `Flag shorthand -n has been deprecated, please use --noshorthandflag only` when the shorthand "n" is used.
+
+Note that usage message is essential here, and it should not be empty.
+
+## Hidden flags
+It is possible to mark a flag as hidden, meaning it will still function as normal, however will not show up in usage/help text.
+
+**Example**: You have a flag named "secretFlag" that you need for internal use only and don't want it showing up in help text, or for its usage text to be available.
+```go
+// hide a flag by specifying its name
+flags.MarkHidden("secretFlag")
+```
+
+## Disable sorting of flags
+`pflag` allows you to disable sorting of flags for help and usage message.
+
+**Example**:
+```go
+flags.BoolP("verbose", "v", false, "verbose output")
+flags.String("coolflag", "yeaah", "it's really cool flag")
+flags.Int("usefulflag", 777, "sometimes it's very useful")
+flags.SortFlags = false
+flags.PrintDefaults()
+```
+**Output**:
+```
+  -v, --verbose           verbose output
+      --coolflag string   it's really cool flag (default "yeaah")
+      --usefulflag int    sometimes it's very useful (default 777)
+```
+
+
+## Supporting Go flags when using pflag
+In order to support flags defined using Go's `flag` package, they must be added to the `pflag` flagset. This is usually necessary
+to support flags defined by third-party dependencies (e.g. `golang/glog`).
+
+**Example**: You want to add the Go flags to the `CommandLine` flagset
+```go
+import (
+	goflag "flag"
+	flag "github.com/spf13/pflag"
+)
+
+var ip *int = flag.Int("flagname", 1234, "help message for flagname")
+
+func main() {
+	flag.CommandLine.AddGoFlagSet(goflag.CommandLine)
+	flag.Parse()
+}
+```
+
+## More info
+
+You can see the full reference documentation of the pflag package
+[at godoc.org][3], or through go's standard documentation system by
+running `godoc -http=:6060` and browsing to
+[http://localhost:6060/pkg/github.com/spf13/pflag][2] after
+installation.

+Package pflag is a drop-in replacement for Go's flag package, implementing
+POSIX/GNU-style --flags.
+
+pflag is compatible with the GNU extensions to the POSIX recommendations
+for command-line options. See
+http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
+
+Usage:
+
+pflag is a drop-in replacement of Go's native flag package. If you import
+pflag under the name "flag" then all code should continue to function
+with no changes.
+
+	import flag "github.com/spf13/pflag"
+
+There is one exception to this: if you directly instantiate the Flag struct
+there is one more field "Shorthand" that you will need to set.
+Most code never instantiates this struct directly, and instead uses
+functions such as String(), BoolVar(), and Var(), and is therefore
+unaffected.
+
+Define flags using flag.String(), Bool(), Int(), etc.
+
+This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
+	var ip = flag.Int("flagname", 1234, "help message for flagname")
+If you like, you can bind the flag to a variable using the Var() functions.
+	var flagvar int
+	func init() {
+		flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
+	}
+Or you can create custom flags that satisfy the Value interface (with
+pointer receivers) and couple them to flag parsing by
+	flag.Var(&flagVal, "name", "help message for flagname")
+For such flags, the default value is just the initial value of the variable.
+
+After all flags are defined, call
+	flag.Parse()
+to parse the command line into the defined flags.
+
+Flags may then be used directly. If you're using the flags themselves,
+they are all pointers; if you bind to variables, they're values.
+	fmt.Println("ip has value ", *ip)
+	fmt.Println("flagvar has value ", flagvar)
+
+After parsing, the arguments after the flag are available as the
+slice flag.Args() or individually as flag.Arg(i).
+The arguments are indexed from 0 through flag.NArg()-1.
+
+The pflag package also defines some new functions that are not in flag,
+that give one-letter shorthands for flags. You can use these by appending
+'P' to the name of any function that defines a flag.
+	var ip = flag.IntP("flagname", "f", 1234, "help message")
+	var flagvar bool
+	func init() {
+		flag.BoolVarP("boolname", "b", true, "help message")
+	}
+	flag.VarP(&flagVar, "varname", "v", 1234, "help message")
+Shorthand letters can be used with single dashes on the command line.
+Boolean shorthand flags can be combined with other shorthand flags.
+
+Command line flag syntax:
+	--flag    // boolean flags only
+	--flag=x
+
+Unlike the flag package, a single dash before an option means something
+different than a double dash. Single dashes signify a series of shorthand
+letters for flags. All but the last shorthand letter must be boolean flags.
+	// boolean flags
+	-f
+	-abc
+	// non-boolean flags
+	-n 1234
+	-Ifile
+	// mixed
+	-abcs "hello"
+	-abcn1234
+
+Flag parsing stops after the terminator "--". Unlike the flag package,
+flags can be interspersed with arguments anywhere on the command line
+before this terminator.
+
+Integer flags accept 1234, 0664, 0x1234 and may be negative.
+Boolean flags (in their long form) accept 1, 0, t, f, true, false,
+TRUE, FALSE, True, False.
+Duration flags accept any input valid for time.ParseDuration.
+
+The default set of command-line flags is controlled by
+top-level functions.  The FlagSet type allows one to define
+independent sets of flags, such as to implement subcommands
+in a command-line interface. The methods of FlagSet are
+analogous to the top-level functions for the command-line
+flag set.

+Package codec provides a
+High Performance, Feature-Rich Idiomatic Go 1.4+ codec/encoding library
+for binc, msgpack, cbor, json.
+
+Supported Serialization formats are:
+
+  - msgpack: https://github.com/msgpack/msgpack
+  - binc:    http://github.com/ugorji/binc
+  - cbor:    http://cbor.io http://tools.ietf.org/html/rfc7049
+  - json:    http://json.org http://tools.ietf.org/html/rfc7159
+  - simple:
+
+To install:
+
+    go get github.com/ugorji/go/codec
+
+This package will carefully use 'unsafe' for performance reasons in specific places.
+You can build without unsafe use by passing the safe or appengine tag
+i.e. 'go install -tags=safe ...'. Note that unsafe is only supported for the last 3
+go sdk versions e.g. current go release is go 1.9, so we support unsafe use only from
+go 1.7+ . This is because supporting unsafe requires knowledge of implementation details.
+
+For detailed usage information, read the primer at http://ugorji.net/blog/go-codec-primer .
+
+The idiomatic Go support is as seen in other encoding packages in
+the standard library (ie json, xml, gob, etc).
+
+Rich Feature Set includes:
+
+  - Simple but extremely powerful and feature-rich API
+  - Support for go1.4 and above, while selectively using newer APIs for later releases
+  - Excellent code coverage ( > 90% )
+  - Very High Performance.
+    Our extensive benchmarks show us outperforming Gob, Json, Bson, etc by 2-4X.
+  - Careful selected use of 'unsafe' for targeted performance gains.
+    100% mode exists where 'unsafe' is not used at all.
+  - Lock-free (sans mutex) concurrency for scaling to 100's of cores
+  - Coerce types where appropriate
+    e.g. decode an int in the stream into a float, decode numbers from formatted strings, etc
+  - Corner Cases:
+    Overflows, nil maps/slices, nil values in streams are handled correctly
+  - Standard field renaming via tags
+  - Support for omitting empty fields during an encoding
+  - Encoding from any value and decoding into pointer to any value
+    (struct, slice, map, primitives, pointers, interface{}, etc)
+  - Extensions to support efficient encoding/decoding of any named types
+  - Support encoding.(Binary|Text)(M|Unm)arshaler interfaces
+  - Support IsZero() bool to determine if a value is a zero value.
+    Analogous to time.Time.IsZero() bool.
+  - Decoding without a schema (into a interface{}).
+    Includes Options to configure what specific map or slice type to use
+    when decoding an encoded list or map into a nil interface{}
+  - Mapping a non-interface type to an interface, so we can decode appropriately
+    into any interface type with a correctly configured non-interface value.
+  - Encode a struct as an array, and decode struct from an array in the data stream
+  - Option to encode struct keys as numbers (instead of strings)
+    (to support structured streams with fields encoded as numeric codes)
+  - Comprehensive support for anonymous fields
+  - Fast (no-reflection) encoding/decoding of common maps and slices
+  - Code-generation for faster performance.
+  - Support binary (e.g. messagepack, cbor) and text (e.g. json) formats
+  - Support indefinite-length formats to enable true streaming
+    (for formats which support it e.g. json, cbor)
+  - Support canonical encoding, where a value is ALWAYS encoded as same sequence of bytes.
+    This mostly applies to maps, where iteration order is non-deterministic.
+  - NIL in data stream decoded as zero value
+  - Never silently skip data when decoding.
+    User decides whether to return an error or silently skip data when keys or indexes
+    in the data stream do not map to fields in the struct.
+  - Detect and error when encoding a cyclic reference (instead of stack overflow shutdown)
+  - Encode/Decode from/to chan types (for iterative streaming support)
+  - Drop-in replacement for encoding/json. `json:` key in struct tag supported.
+  - Provides a RPC Server and Client Codec for net/rpc communication protocol.
+  - Handle unique idiosyncrasies of codecs e.g.
+    - For messagepack, configure how ambiguities in handling raw bytes are resolved
+    - For messagepack, provide rpc server/client codec to support
+      msgpack-rpc protocol defined at:
+      https://github.com/msgpack-rpc/msgpack-rpc/blob/master/spec.md
+
+Extension Support
+
+Users can register a function to handle the encoding or decoding of
+their custom types.
+
+There are no restrictions on what the custom type can be. Some examples:
+
+    type BisSet   []int
+    type BitSet64 uint64
+    type UUID     string
+    type MyStructWithUnexportedFields struct { a int; b bool; c []int; }
+    type GifImage struct { ... }
+
+As an illustration, MyStructWithUnexportedFields would normally be
+encoded as an empty map because it has no exported fields, while UUID
+would be encoded as a string. However, with extension support, you can
+encode any of these however you like.
+
+Custom Encoding and Decoding
+
+This package maintains symmetry in the encoding and decoding halfs.
+We determine how to encode or decode by walking this decision tree
+
+  - is type a codec.Selfer?
+  - is there an extension registered for the type?
+  - is format binary, and is type a encoding.BinaryMarshaler and BinaryUnmarshaler?
+  - is format specifically json, and is type a encoding/json.Marshaler and Unmarshaler?
+  - is format text-based, and type an encoding.TextMarshaler?
+  - else we use a pair of functions based on the "kind" of the type e.g. map, slice, int64, etc
+
+This symmetry is important to reduce chances of issues happening because the
+encoding and decoding sides are out of sync e.g. decoded via very specific
+encoding.TextUnmarshaler but encoded via kind-specific generalized mode.
+
+Consequently, if a type only defines one-half of the symmetry
+(e.g. it implements UnmarshalJSON() but not MarshalJSON() ),
+then that type doesn't satisfy the check and we will continue walking down the
+decision tree.
+
+RPC
+
+RPC Client and Server Codecs are implemented, so the codecs can be used
+with the standard net/rpc package.
+
+Usage
+
+The Handle is SAFE for concurrent READ, but NOT SAFE for concurrent modification.
+
+The Encoder and Decoder are NOT safe for concurrent use.
+
+Consequently, the usage model is basically:
+
+    - Create and initialize the Handle before any use.
+      Once created, DO NOT modify it.
+    - Multiple Encoders or Decoders can now use the Handle concurrently.
+      They only read information off the Handle (never write).
+    - However, each Encoder or Decoder MUST not be used concurrently
+    - To re-use an Encoder/Decoder, call Reset(...) on it first.
+      This allows you use state maintained on the Encoder/Decoder.
+
+Sample usage model:
+
+    // create and configure Handle
+    var (
+      bh codec.BincHandle
+      mh codec.MsgpackHandle
+      ch codec.CborHandle
+    )
+
+    mh.MapType = reflect.TypeOf(map[string]interface{}(nil))
+
+    // configure extensions
+    // e.g. for msgpack, define functions and enable Time support for tag 1
+    // mh.SetExt(reflect.TypeOf(time.Time{}), 1, myExt)
+
+    // create and use decoder/encoder
+    var (
+      r io.Reader
+      w io.Writer
+      b []byte
+      h = &bh // or mh to use msgpack
+    )
+
+    dec = codec.NewDecoder(r, h)
+    dec = codec.NewDecoderBytes(b, h)
+    err = dec.Decode(&v)
+
+    enc = codec.NewEncoder(w, h)
+    enc = codec.NewEncoderBytes(&b, h)
+    err = enc.Encode(v)
+
+    //RPC Server
+    go func() {
+        for {
+            conn, err := listener.Accept()
+            rpcCodec := codec.GoRpc.ServerCodec(conn, h)
+            //OR rpcCodec := codec.MsgpackSpecRpc.ServerCodec(conn, h)
+            rpc.ServeCodec(rpcCodec)
+        }
+    }()
+
+    //RPC Communication (client side)
+    conn, err = net.Dial("tcp", "localhost:5555")
+    rpcCodec := codec.GoRpc.ClientCodec(conn, h)
+    //OR rpcCodec := codec.MsgpackSpecRpc.ClientCodec(conn, h)
+    client := rpc.NewClientWithCodec(rpcCodec)
+
+Running Tests
+
+To run tests, use the following:
+
+    go test
+
+To run the full suite of tests, use the following:
+
+    go test -tags alltests -run Suite
+
+You can run the tag 'safe' to run tests or build in safe mode. e.g.
+
+    go test -tags safe -run Json
+    go test -tags "alltests safe" -run Suite
+
+Running Benchmarks
+
+Please see http://github.com/ugorji/go-codec-bench .
+
+Caveats
+
+Struct fields matching the following are ignored during encoding and decoding
+    - struct tag value set to -
+    - func, complex numbers, unsafe pointers
+    - unexported and not embedded
+    - unexported and embedded and not struct kind
+    - unexported and embedded pointers (from go1.10)
+
+Every other field in a struct will be encoded/decoded.
+
+Embedded fields are encoded as if they exist in the top-level struct,
+with some caveats. See Encode documentation.

+// TODO:
+//   - For Go 1.11, when mid-stack inlining is enabled,
+//     we should use committed functions for writeXXX and readXXX calls.
+//     This involves uncommenting the methods for decReaderSwitch and encWriterSwitch
+//     and using those (decReaderSwitch and encWriterSwitch) in all handles
+//     instead of encWriter and decReader.
+//     The benefit is that, for the (En|De)coder over []byte, the encWriter/decReader
+//     will be inlined, giving a performance bump for that typical case.
+//     However, it will only  be inlined if mid-stack inlining is enabled,
+//     as we call panic to raise errors, and panic currently prevents inlining.
+//
+// PUNTED:
+//   - To make Handle comparable, make extHandle in BasicHandle a non-embedded pointer,
+//     and use overlay methods on *BasicHandle to call through to extHandle after initializing
+//     the "xh *extHandle" to point to a real slice.
+//
+// BEFORE EACH RELEASE:
+//   - Look through and fix padding for each type, to eliminate false sharing
+//     - critical shared objects that are read many times
+//       TypeInfos
+//     - pooled objects:
+//       decNaked, decNakedContainers, codecFner, typeInfoLoadArray, 
+//     - small objects allocated independently, that we read/use much across threads:
+//       codecFn, typeInfo
+//     - Objects allocated independently and used a lot
+//       Decoder, Encoder,
+//       xxxHandle, xxxEncDriver, xxxDecDriver (xxx = json, msgpack, cbor, binc, simple)
+//     - In all above, arrange values modified together to be close to each other.
+//
+//     For all of these, either ensure that they occupy full cache lines,
+//     or ensure that the things just past the cache line boundary are hardly read/written
+//     e.g. JsonHandle.RawBytesExt - which is copied into json(En|De)cDriver at init
+//
+//     Occupying full cache lines means they occupy 8*N words (where N is an integer).
+//     Check this out by running: ./run.sh -z
+//     - look at those tagged ****, meaning they are not occupying full cache lines
+//     - look at those tagged <<<<, meaning they are larger than 32 words (something to watch)
+//   - Run "golint -min_confidence 0.81"

+// EncodeTime encodes a time.Time as a []byte, including

+//
+// Format Description
+//
+//   A timestamp is composed of 3 components:
+//
+//   - secs: signed integer representing seconds since unix epoch
+//   - nsces: unsigned integer representing fractional seconds as a
+//     nanosecond offset within secs, in the range 0 <= nsecs < 1e9
+//   - tz: signed integer representing timezone offset in minutes east of UTC,
+//     and a dst (daylight savings time) flag
+//
+//   When encoding a timestamp, the first byte is the descriptor, which
+//   defines which components are encoded and how many bytes are used to
+//   encode secs and nsecs components. *If secs/nsecs is 0 or tz is UTC, it
+//   is not encoded in the byte array explicitly*.
+//
+//       Descriptor 8 bits are of the form `A B C DDD EE`:
+//           A:   Is secs component encoded? 1 = true
+//           B:   Is nsecs component encoded? 1 = true
+//           C:   Is tz component encoded? 1 = true
+//           DDD: Number of extra bytes for secs (range 0-7).
+//                If A = 1, secs encoded in DDD+1 bytes.
+//                    If A = 0, secs is not encoded, and is assumed to be 0.
+//                    If A = 1, then we need at least 1 byte to encode secs.
+//                    DDD says the number of extra bytes beyond that 1.
+//                    E.g. if DDD=0, then secs is represented in 1 byte.
+//                         if DDD=2, then secs is represented in 3 bytes.
+//           EE:  Number of extra bytes for nsecs (range 0-3).
+//                If B = 1, nsecs encoded in EE+1 bytes (similar to secs/DDD above)
+//
+//   Following the descriptor bytes, subsequent bytes are:
+//
+//       secs component encoded in `DDD + 1` bytes (if A == 1)
+//       nsecs component encoded in `EE + 1` bytes (if B == 1)
+//       tz component encoded in 2 bytes (if C == 1)
+//
+//   secs and nsecs components are integers encoded in a BigEndian
+//   2-complement encoding format.
+//
+//   tz component is encoded as 2 bytes (16 bits). Most significant bit 15 to
+//   Least significant bit 0 are described below:
+//
+//       Timezone offset has a range of -12:00 to +14:00 (ie -720 to +840 minutes).
+//       Bit 15 = have\_dst: set to 1 if we set the dst flag.
+//       Bit 14 = dst\_on: set to 1 if dst is in effect at the time, or 0 if not.
+//       Bits 13..0 = timezone offset in minutes. It is a signed integer in Big Endian format.

+// Configurations exist on the Handle to override defaults
+// (e.g. for MapType, SliceType and how to decode raw bytes).

+// When decoding into a non-nil interface{} value, the mode of encoding is based on the

+//   - If an extension is registered for it, call that extension function
+//   - If it implements BinaryUnmarshaler, call its UnmarshalBinary(data []byte) error
+//   - Else decode it based on its reflect.Kind
+//
+// There are some special rules when decoding into containers (slice/array/map/struct).
+// Decode will typically use the stream contents to UPDATE the container.
+//   - A map can be decoded from a stream map, by updating matching keys.
+//   - A slice can be decoded from a stream array,

+//   - A slice can be decoded from a stream map, by decoding as if
+//     it contains a sequence of key-value pairs.
+//   - A struct can be decoded from a stream map, by updating matching fields.
+//   - A struct can be decoded from a stream array,
+//     by updating fields as they occur in the struct (by index).
+//
+// When decoding a stream map or array with length of 0 into a nil map or slice,
+// we reset the destination map or slice to a zero-length value.
+//
+// However, when decoding a stream nil, we reset the destination container
+// to its "zero" value (e.g. nil for slice/map, etc).

+//    - uint: so struct key names are encoded as unsigned integers (instead of strings)
+//    - float: so struct key names are encoded as floats (instead of strings)
+// More details on these below.
+//
+// Struct values "usually" encode as maps. Each exported struct field is encoded unless:
+//    - the field's tag is "-", OR
+//    - the field is empty (empty or the zero value) and its tag specifies the "omitempty" option.
+//
+// When encoding as a map, the first string in the tag (before the comma)
+// is the map key string to use when encoding.
+// ...
+// This key is typically encoded as a string.
+// However, there are instances where the encoded stream has mapping keys encoded as numbers.
+// For example, some cbor streams have keys as integer codes in the stream, but they should map
+// to fields in a structured object. Consequently, a struct is the natural representation in code.
+// For these, configure the struct to encode/decode the keys as numbers (instead of string).
+// This is done with the int,uint or float option on the _struct field (see above).
+//
+// However, struct values may encode as arrays. This happens when:
+//    - StructToArray Encode option is set, OR
+//    - the tag on the _struct field sets the "toarray" option
+// Note that omitempty is ignored when encoding struct values as arrays,
+// as an entry must be encoded for each field, to maintain its position.
+//
+// Values with types that implement MapBySlice are encoded as stream maps.
+//
+// The empty values (for omitempty option) are false, 0, any nil pointer
+// or interface value, and any array, slice, map, or string of length zero.
+//
+// Anonymous fields are encoded inline except:
+//    - the struct tag specifies a replacement name (first value)
+//    - the field is of an interface type
+//
+// Examples:
+//
+//      // NOTE: 'json:' can be used as struct tag key, in place 'codec:' below.
+//      type MyStruct struct {
+//          _struct bool    `codec:",omitempty"`   //set omitempty for every field
+//          Field1 string   `codec:"-"`            //skip this field
+//          Field2 int      `codec:"myName"`       //Use key "myName" in encode stream
+//          Field3 int32    `codec:",omitempty"`   //use key "Field3". Omit if empty.
+//          Field4 bool     `codec:"f4,omitempty"` //use key "f4". Omit if empty.
+//          io.Reader                              //use key "Reader".
+//          MyStruct        `codec:"my1"           //use key "my1".
+//          MyStruct                               //inline it
+//          ...
+//      }
+//
+//      type MyStruct struct {
+//          _struct bool    `codec:",toarray"`     //encode struct as an array
+//      }
+//
+//      type MyStruct struct {
+//          _struct bool    `codec:",uint"`        //encode struct with "unsigned integer" keys
+//          Field1 string   `codec:"1"`            //encode Field1 key using: EncodeInt(1)
+//          Field2 string   `codec:"2"`            //encode Field2 key using: EncodeInt(2)
+//      }
+//
+// The mode of encoding is based on the type of the value. When a value is seen:
+//   - If a Selfer, call its CodecEncodeSelf method
+//   - If an extension is registered for it, call that extension function
+//   - If implements encoding.(Binary|Text|JSON)Marshaler, call Marshal(Binary|Text|JSON) method
+//   - Else encode it based on its reflect.Kind
+//
+// Note that struct field names and keys in map[string]XXX will be treated as symbols.
+// Some formats support symbols (e.g. binc) and will properly encode the string
+// only once in the stream, and use a tag to refer to it thereafter.

+// Fast path functions try to create a fast path encode or decode implementation
+// for common maps and slices.
+//
+// We define the functions and register then in this single file
+// so as not to pollute the encode.go and decode.go, and create a dependency in there.
+// This file can be omitted without causing a build failure.
+//
+// The advantage of fast paths is:
+//	  - Many calls bypass reflection altogether
+//
+// Currently support
+//	  - slice of all builtin types,
+//	  - map of all builtin types to string or interface value
+//	  - symmetrical maps of all builtin types (e.g. str-str, uint8-uint8)
+// This should provide adequate "typical" implementations.
+//
+// Note that fast track decode functions must handle values for which an address cannot be obtained.
+// For example:
+//	 m2 := map[string]int{}
+//	 p2 := []interface{}{m2}
+//	 // decoding into p2 will bomb if fast track functions do not treat like unaddressable.

+// Fast path functions try to create a fast path encode or decode implementation
+// for common maps and slices.
+//
+// We define the functions and register then in this single file
+// so as not to pollute the encode.go and decode.go, and create a dependency in there.
+// This file can be omitted without causing a build failure.
+//
+// The advantage of fast paths is:
+//	  - Many calls bypass reflection altogether
+// 
+// Currently support
+//	  - slice of all builtin types,
+//	  - map of all builtin types to string or interface value
+//	  - symmetrical maps of all builtin types (e.g. str-str, uint8-uint8)
+// This should provide adequate "typical" implementations.
+// 
+// Note that fast track decode functions must handle values for which an address cannot be obtained.
+// For example: 
+//	 m2 := map[string]int{}
+//	 p2 := []interface{}{m2}
+//	 // decoding into p2 will bomb if fast track functions do not treat like unaddressable.
+//

+// ---------------------------------------------------
+// codecgen supports the full cycle of reflection-based codec:
+//    - RawExt
+//    - Raw
+//    - Extensions
+//    - (Binary|Text|JSON)(Unm|M)arshal
+//    - generic by-kind
+//
+// This means that, for dynamic things, we MUST use reflection to at least get the reflect.Type.
+// In those areas, we try to only do reflection or interface-conversion when NECESSARY:
+//    - Extensions, only if Extensions are configured.
+//
+// However, codecgen doesn't support the following:
+//   - Canonical option. (codecgen IGNORES it currently)
+//     This is just because it has not been implemented.
+//
+// During encode/decode, Selfer takes precedence.
+// A type implementing Selfer will know how to encode/decode itself statically.
+//
+// The following field types are supported:
+//     array: [n]T
+//     slice: []T
+//     map: map[K]V
+//     primitive: [u]int[n], float(32|64), bool, string
+//     struct
+//
+// ---------------------------------------------------
+// Note that a Selfer cannot call (e|d).(En|De)code on itself,
+// as this will cause a circular reference, as (En|De)code will call Selfer methods.
+// Any type that implements Selfer must implement completely and not fallback to (En|De)code.
+//
+// In addition, code in this file manages the generation of fast-path implementations of
+// encode/decode of slices/maps of primitive keys/values.
+//
+// Users MUST re-generate their implementations whenever the code shape changes.
+// The generated code will panic if it was generated with a version older than the supporting library.
+// ---------------------------------------------------
+//
+// codec framework is very feature rich.
+// When encoding or decoding into an interface, it depends on the runtime type of the interface.
+// The type of the interface may be a named type, an extension, etc.
+// Consequently, we fallback to runtime codec for encoding/decoding interfaces.
+// In addition, we fallback for any value which cannot be guaranteed at runtime.
+// This allows us support ANY value, including any named types, specifically those which
+// do not implement our interfaces (e.g. Selfer).
+//
+// This explains some slowness compared to other code generation codecs (e.g. msgp).
+// This reduction in speed is only seen when your refers to interfaces,
+// e.g. type T struct { A interface{}; B []interface{}; C map[string]interface{} }
+//
+// codecgen will panic if the file was generated with an old version of the library in use.
+//
+// Note:
+//   It was a conscious decision to have gen.go always explicitly call EncodeNil or TryDecodeAsNil.
+//   This way, there isn't a function call overhead just to see that we should not enter a block of code.
+//
+// Note:
+//   codecgen-generated code depends on the variables defined by fast-path.generated.go.
+//   consequently, you cannot run with tags "codecgen notfastpath".
+
+// GenVersion is the current version of codecgen.
+//
+// NOTE: Increment this value each time codecgen changes fundamentally.
+// Fundamental changes are:
+//   - helper methods change (signature change, new ones added, some removed, etc)
+//   - codecgen command line changes
+//
+// v1: Initial Version
+// v2:
+// v3: Changes for Kubernetes:
+//     changes in signature of some unpublished helper methods and codecgen cmdline arguments.
+// v4: Removed separator support from (en|de)cDriver, and refactored codec(gen)
+// v5: changes to support faster json decoding. Let encoder/decoder maintain state of collections.
+// v6: removed unsafe from gen, and now uses codecgen.exec tag
+// v7:
+// v8: current - we now maintain compatibility with old generated code.

+// Contains code shared by both encode and decode.
+
+// Some shared ideas around encoding/decoding
+// ------------------------------------------
+//
+// If an interface{} is passed, we first do a type assertion to see if it is
+// a primitive type or a map/slice of primitive types, and use a fastpath to handle it.
+//
+// If we start with a reflect.Value, we are already in reflect.Value land and
+// will try to grab the function for the underlying Type and directly call that function.
+// This is more performant than calling reflect.Value.Interface().
+//
+// This still helps us bypass many layers of reflection, and give best performance.
+//
+// Containers
+// ------------
+// Containers in the stream are either associative arrays (key-value pairs) or
+// regular arrays (indexed by incrementing integers).
+//
+// Some streams support indefinite-length containers, and use a breaking
+// byte-sequence to denote that the container has come to an end.
+//
+// Some streams also are text-based, and use explicit separators to denote the
+// end/beginning of different values.
+//
+// During encode, we use a high-level condition to determine how to iterate through
+// the container. That decision is based on whether the container is text-based (with
+// separators) or binary (without separators). If binary, we do not even call the
+// encoding of separators.
+//
+// During decode, we use a different high-level condition to determine how to iterate
+// through the containers. That decision is based on whether the stream contained
+// a length prefix, or if it used explicit breaks. If length-prefixed, we assume that
+// it has to be binary, and we do not even try to read separators.
+//
+// Philosophy
+// ------------
+// On decode, this codec will update containers appropriately:
+//    - If struct, update fields from stream into fields of struct.
+//      If field in stream not found in struct, handle appropriately (based on option).
+//      If a struct field has no corresponding value in the stream, leave it AS IS.
+//      If nil in stream, set value to nil/zero value.
+//    - If map, update map from stream.
+//      If the stream value is NIL, set the map to nil.
+//    - if slice, try to update up to length of array in stream.
+//      if container len is less than stream array length,
+//      and container cannot be expanded, handled (based on option).
+//      This means you can decode 4-element stream array into 1-element array.
+//
+// ------------------------------------
+// On encode, user can specify omitEmpty. This means that the value will be omitted
+// if the zero value. The problem may occur during decode, where omitted values do not affect
+// the value being decoded into. This means that if decoding into a struct with an
+// int field with current value=5, and the field is omitted in the stream, then after
+// decoding, the value will still be 5 (not 0).
+// omitEmpty only works if you guarantee that you always decode into zero-values.
+//
+// ------------------------------------
+// We could have truncated a map to remove keys not available in the stream,
+// or set values in the struct which are not in the stream to their zero values.
+// We decided against it because there is no efficient way to do it.
+// We may introduce it as an option later.
+// However, that will require enabling it for both runtime and code generation modes.
+//
+// To support truncate, we need to do 2 passes over the container:
+//   map
+//   - first collect all keys (e.g. in k1)
+//   - for each key in stream, mark k1 that the key should not be removed
+//   - after updating map, do second pass and call delete for all keys in k1 which are not marked
+//   struct:
+//   - for each field, track the *typeInfo s1
+//   - iterate through all s1, and for each one not marked, set value to zero
+//   - this involves checking the possible anonymous fields which are nil ptrs.
+//     too much work.
+//
+// ------------------------------------------
+// Error Handling is done within the library using panic.
+//
+// This way, the code doesn't have to keep checking if an error has happened,
+// and we don't have to keep sending the error value along with each call
+// or storing it in the En|Decoder and checking it constantly along the way.
+//
+// The disadvantage is that small functions which use panics cannot be inlined.
+// The code accounts for that by only using panics behind an interface;
+// since interface calls cannot be inlined, this is irrelevant.
+//
+// We considered storing the error is En|Decoder.
+//   - once it has its err field set, it cannot be used again.
+//   - panicing will be optional, controlled by const flag.
+//   - code should always check error first and return early.
+// We eventually decided against it as it makes the code clumsier to always
+// check for these error conditions.

+// Json is comprehensively supported:
+//    - decodes numbers into interface{} as int, uint or float64
+//      based on how the number looks and some config parameters e.g. PreferFloat, SignedInt, etc.
+//    - decode integers from float formatted numbers e.g. 1.27e+8
+//    - decode any json value (numbers, bool, etc) from quoted strings
+//    - configurable way to encode/decode []byte .
+//      by default, encodes and decodes []byte using base64 Std Encoding
+//    - UTF-8 support for encoding and decoding
+//
+// It has better performance than the json library in the standard library,
+// by leveraging the performance improvements of the codec library.
+//
+// In addition, it doesn't read more bytes than necessary during a decode, which allows
+// reading multiple values from a stream containing json and non-json content.
+// For example, a user can read a json value, then a cbor value, then a msgpack value,
+// all from the same stream in sequence.
+//
+// Note that, when decoding quoted strings, invalid UTF-8 or invalid UTF-16 surrogate pairs are
+// not treated as an error. Instead, they are replaced by the Unicode replacement character U+FFFD.

+// SimpleHandle is a Handle for a very simple encoding format.
+//
+// simple is a simplistic codec similar to binc, but not as compact.
+//   - Encoding of a value is always preceded by the descriptor byte (bd)
+//   - True, false, nil are encoded fully in 1 byte (the descriptor)
+//   - Integers (intXXX, uintXXX) are encoded in 1, 2, 4 or 8 bytes (plus a descriptor byte).
+//     There are positive (uintXXX and intXXX >= 0) and negative (intXXX < 0) integers.
+//   - Floats are encoded in 4 or 8 bytes (plus a descriptor byte)
+//   - Length of containers (strings, bytes, array, map, extensions)
+//     are encoded in 0, 1, 2, 4 or 8 bytes.
+//     Zero-length containers have no length encoded.
+//     For others, the number of bytes is given by pow(2, bd%3)
+//   - maps are encoded as [bd] [length] [[key][value]]...
+//   - arrays are encoded as [bd] [length] [value]...
+//   - extensions are encoded as [bd] [length] [tag] [byte]...
+//   - strings/bytearrays are encoded as [bd] [length] [byte]...
+//   - time.Time are encoded as [bd] [length] [byte]...

+
+A strict Non-validating namespace-aware XML 1.0 parser and (en|de)coder.
+
+We are attempting this due to perceived issues with encoding/xml:
+  - Complicated. It tried to do too much, and is not as simple to use as json.
+  - Due to over-engineering, reflection is over-used AND performance suffers:
+    java is 6X faster:http://fabsk.eu/blog/category/informatique/dev/golang/
+    even PYTHON performs better: http://outgoing.typepad.com/outgoing/2014/07/exploring-golang.html
+
+codec framework will offer the following benefits
+  - VASTLY improved performance (when using reflection-mode or codecgen)
+  - simplicity and consistency: with the rest of the supported formats
+  - all other benefits of codec framework (streaming, codegeneration, etc)
+
+codec is not a drop-in replacement for encoding/xml.
+It is a replacement, based on the simplicity and performance of codec.
+Look at it like JAXB for Go.
+
+Challenges:
+  - Need to output XML preamble, with all namespaces at the right location in the output.
+  - Each "end" block is dynamic, so we need to maintain a context-aware stack
+  - How to decide when to use an attribute VS an element
+  - How to handle chardata, attr, comment EXPLICITLY.
+  - Should it output fragments?
+    e.g. encoding a bool should just output true OR false, which is not well-formed XML.
+
+Extend the struct tag. See representative example:
+  type X struct {
+    ID uint8 `codec:"http://ugorji.net/x-namespace xid id,omitempty,toarray,attr,cdata"`
+    // format: [namespace-uri ][namespace-prefix ]local-name, ...
+  }
+
+Based on this, we encode
+  - fields as elements, BUT
+    encode as attributes if struct tag contains ",attr" and is a scalar (bool, number or string)
+  - text as entity-escaped text, BUT encode as CDATA if struct tag contains ",cdata".
+
+To handle namespaces:
+  - XMLHandle is denoted as being namespace-aware.
+    Consequently, we WILL use the ns:name pair to encode and decode if defined, else use the plain name.
+  - *Encoder and *Decoder know whether the Handle "prefers" namespaces.
+  - add *Encoder.getEncName(*structFieldInfo).
+    No one calls *structFieldInfo.indexForEncName directly anymore
+  - OR better yet: indexForEncName is namespace-aware, and helper.go is all namespace-aware
+    indexForEncName takes a parameter of the form namespace:local-name OR local-name
+  - add *Decoder.getStructFieldInfo(encName string) // encName here is either like abc, or h1:nsabc
+    by being a method on *Decoder, or maybe a method on the Handle itself.
+    No one accesses .encName anymore
+  - let encode.go and decode.go use these (for consistency)
+  - only problem exists for gen.go, where we create a big switch on encName.
+    Now, we also have to add a switch on strings.endsWith(kName, encNsName)
+    - gen.go will need to have many more methods, and then double-on the 2 switch loops like:
+      switch k {
+        case "abc" : x.abc()
+        case "def" : x.def()
+        default {
+          switch {
+            case !nsAware: panic(...)
+            case strings.endsWith(":abc"): x.abc()
+            case strings.endsWith(":def"): x.def()
+            default: panic(...)
+          }
+        }
+     }
+
+The structure below accommodates this:
+
+  type typeInfo struct {
+    sfi []*structFieldInfo // sorted by encName
+    sfins // sorted by namespace
+    sfia  // sorted, to have those with attributes at the top. Needed to write XML appropriately.
+    sfip  // unsorted
+  }
+  type structFieldInfo struct {
+    encName
+    nsEncName
+    ns string
+    attr bool
+    cdata bool
+  }
+
+indexForEncName is now an internal helper function that takes a sorted array
+(one of ti.sfins or ti.sfi). It is only used by *Encoder.getStructFieldInfo(...)
+
+There will be a separate parser from the builder.
+The parser will have a method: next() xmlToken method. It has lookahead support,
+so you can pop multiple tokens, make a determination, and push them back in the order popped.
+This will be needed to determine whether we are "nakedly" decoding a container or not.
+The stack will be implemented using a slice and push/pop happens at the [0] element.
+
+xmlToken has fields:
+  - type uint8: 0 | ElementStart | ElementEnd | AttrKey | AttrVal | Text
+  - value string
+  - ns string
+
+SEE: http://www.xml.com/pub/a/98/10/guide0.html?page=3#ENTDECL
+
+The following are skipped when parsing:
+  - External Entities (from external file)
+  - Notation Declaration e.g. <!NOTATION GIF87A SYSTEM "GIF">
+  - Entity Declarations & References
+  - XML Declaration (assume UTF-8)
+  - XML Directive i.e. <! ... >
+  - Other Declarations: Notation, etc.
+  - Comment
+  - Processing Instruction
+  - schema / DTD for validation:
+    We are not a VALIDATING parser. Validation is done elsewhere.
+    However, some parts of the DTD internal subset are used (SEE BELOW).
+    For Attribute List Declarations e.g.
+    <!ATTLIST foo:oldjoke name ID #REQUIRED label CDATA #IMPLIED status ( funny | notfunny ) 'funny' >
+    We considered using the ATTLIST to get "default" value, but not to validate the contents. (VETOED)
+
+The following XML features are supported
+  - Namespace
+  - Element
+  - Attribute
+  - cdata
+  - Unicode escape
+
+The following DTD (when as an internal sub-set) features are supported:
+  - Internal Entities e.g.
+    <!ELEMENT burns "ugorji is cool" > AND entities for the set: [<>&"']
+  - Parameter entities e.g.
+    <!ENTITY % personcontent "ugorji is cool"> <!ELEMENT burns (%personcontent;)*>
+
+At decode time, a structure containing the following is kept
+  - namespace mapping
+  - default attribute values
+  - all internal entities (<>&"' and others written in the document)
+
+When decode starts, it parses XML namespace declarations and creates a map in the
+xmlDecDriver. While parsing, that map continuously gets updated.
+The only problem happens when a namespace declaration happens on the node that it defines.
+e.g. <hn:name xmlns:hn="http://www.ugorji.net" >
+To handle this, each Element must be fully parsed at a time,
+even if it amounts to multiple tokens which are returned one at a time on request.
+
+xmlns is a special attribute name.
+  - It is used to define namespaces, including the default
+  - It is never returned as an AttrKey or AttrVal.
+  *We may decide later to allow user to use it e.g. you want to parse the xmlns mappings into a field.*
+
+Number, bool, null, mapKey, etc can all be decoded from any xmlToken.
+This accommodates map[int]string for example.
+
+It should be possible to create a schema from the types,
+or vice versa (generate types from schema with appropriate tags).
+This is however out-of-scope from this parsing project.
+
+We should write all namespace information at the first point that it is referenced in the tree,
+and use the mapping for all child nodes and attributes. This means that state is maintained
+at a point in the tree. This also means that calls to Decode or MustDecode will reset some state.
+
+When decoding, it is important to keep track of entity references and default attribute values.
+It seems these can only be stored in the DTD components. We should honor them when decoding.
+
+Configuration for XMLHandle will look like this:
+
+  XMLHandle
+    DefaultNS string
+    // Encoding:
+    NS map[string]string // ns URI to key, used for encoding
+    // Decoding: in case ENTITY declared in external schema or dtd, store info needed here
+    Entities map[string]string // map of entity rep to character
+
+
+During encode, if a namespace mapping is not defined for a namespace found on a struct,
+then we create a mapping for it using nsN (where N is 1..1000000, and doesn't conflict
+with any other namespace mapping).
+
+Note that different fields in a struct can have different namespaces.
+However, all fields will default to the namespace on the _struct field (if defined).
+
+An XML document is a name, a map of attributes and a list of children.
+Consequently, we cannot "DecodeNaked" into a map[string]interface{} (for example).
+We have to "DecodeNaked" into something that resembles XML data.
+
+To support DecodeNaked (decode into nil interface{}), we have to define some "supporting" types:
+    type Name struct { // Preferred. Less allocations due to conversions.
+      Local string
+      Space string
+    }
+    type Element struct {
+      Name Name
+      Attrs map[Name]string
+      Children []interface{} // each child is either *Element or string
+    }
+Only two "supporting" types are exposed for XML: Name and Element.
+
+// ------------------
+
+We considered 'type Name string' where Name is like "Space Local" (space-separated).
+We decided against it, because each creation of a name would lead to
+double allocation (first convert []byte to string, then concatenate them into a string).
+The benefit is that it is faster to read Attrs from a map. But given that Element is a value
+object, we want to eschew methods and have public exposed variables.
+
+We also considered the following, where xml types were not value objects, and we used
+intelligent accessor methods to extract information and for performance.
+*** WE DECIDED AGAINST THIS. ***
+    type Attr struct {
+      Name Name
+      Value string
+    }
+    // Element is a ValueObject: There are no accessor methods.
+    // Make element self-contained.
+    type Element struct {
+      Name Name
+      attrsMap map[string]string // where key is "Space Local"
+      attrs []Attr
+      childrenT []string
+      childrenE []Element
+      childrenI []int // each child is a index into T or E.
+    }
+    func (x *Element) child(i) interface{} // returns string or *Element
+
+// ------------------
+
+Per XML spec and our default handling, white space is always treated as
+insignificant between elements, except in a text node. The xml:space='preserve'
+attribute is ignored.
+
+**Note: there is no xml: namespace. The xml: attributes were defined before namespaces.**
+**So treat them as just "directives" that should be interpreted to mean something**.
+
+On encoding, we support indenting aka prettifying markup in the same way we support it for json.
+
+A document or element can only be encoded/decoded from/to a struct. In this mode:
+  - struct name maps to element name (or tag-info from _struct field)
+  - fields are mapped to child elements or attributes
+
+A map is either encoded as attributes on current element, or as a set of child elements.
+Maps are encoded as attributes iff their keys and values are primitives (number, bool, string).
+
+A list is encoded as a set of child elements.
+
+Primitives (number, bool, string) are encoded as an element, attribute or text
+depending on the context.
+
+Extensions must encode themselves as a text string.
+
+Encoding is tough, specifically when encoding mappings, because we need to encode
+as either attribute or element. To do this, we need to default to encoding as attributes,
+and then let Encoder inform the Handle when to start encoding as nodes.
+i.e. Encoder does something like:
+
+    h.EncodeMapStart()
+    h.Encode(), h.Encode(), ...
+    h.EncodeMapNotAttrSignal() // this is not a bool, because it's a signal
+    h.Encode(), h.Encode(), ...
+    h.EncodeEnd()
+
+Only XMLHandle understands this, and will set itself to start encoding as elements.
+
+This support extends to maps. For example, if a struct field is a map, and it has
+the struct tag signifying it should be attr, then all its fields are encoded as attributes.
+e.g.
+
+    type X struct {
+       M map[string]int `codec:"m,attr"` // encode keys as attributes named
+    }
+
+Question:
+  - if encoding a map, what if map keys have spaces in them???
+    Then they cannot be attributes or child elements. Error.
+
+Options to consider adding later:
+  - For attribute values, normalize by trimming beginning and ending white space,
+    and converting every white space sequence to a single space.
+  - ATTLIST restrictions are enforced.
+    e.g. default value of xml:space, skipping xml:XYZ style attributes, etc.
+  - Consider supporting NON-STRICT mode (e.g. to handle HTML parsing).
+    Some elements e.g. br, hr, etc need not close and should be auto-closed
+    ... (see http://www.w3.org/TR/html4/loose.dtd)
+    An expansive set of entities are pre-defined.
+  - Have easy way to create a HTML parser:
+    add a HTML() method to XMLHandle, that will set Strict=false, specify AutoClose,
+    and add HTML Entities to the list.
+  - Support validating element/attribute XMLName before writing it.
+    Keep this behind a flag, which is set to false by default (for performance).
+    type XMLHandle struct {
+      CheckName bool
+    }
+
+Misc:
+
+ROADMAP (1 weeks):
+  - build encoder (1 day)
+  - build decoder (based off xmlParser) (1 day)
+  - implement xmlParser (2 days).
+    Look at encoding/xml for inspiration.
+  - integrate and TEST (1 days)
+  - write article and post it (1 day)

+
+when parsing
+- parse the attributes first
+- then parse the nodes
+
+basically:
+- if encoding a field: we use the field name for the wrapper
+- if encoding a non-field, then just use the element type name
+
+  map[string]string ==> <map><key>abc</key><value>val</value></map>... or
+                        <map key="abc">val</map>... OR
+                        <key1>val1</key1><key2>val2</key2>...                <- PREFERED
+  []string  ==> <string>v1</string><string>v2</string>...
+  string v1 ==> <string>v1</string>
+  bool true ==> <bool>true</bool>
+  float 1.0 ==> <float>1.0</float>
+  ...
+
+  F1 map[string]string ==> <F1><key>abc</key><value>val</value></F1>... OR
+                           <F1 key="abc">val</F1>... OR
+                           <F1><abc>val</abc>...</F1>                        <- PREFERED
+  F2 []string          ==> <F2>v1</F2><F2>v2</F2>...
+  F3 bool              ==> <F3>true</F3>
+  ...
+
+- a scalar is encoded as:
+  (value) of type T  ==> <T><value/></T>
+  (value) of field F ==> <F><value/></F>
+- A kv-pair is encoded as:
+  (key,value) ==> <map><key><value/></key></map> OR <map key="value">
+  (key,value) of field F ==> <F><key><value/></key></F> OR <F key="value">
+- A map or struct is just a list of kv-pairs
+- A list is encoded as sequences of same node e.g.
+  <F1 key1="value11">
+  <F1 key2="value12">
+  <F2>value21</F2>
+  <F2>value22</F2>
+- we may have to singularize the field name, when entering into xml,
+  and pluralize them when encoding.
+- bi-directional encode->decode->encode is not a MUST.
+  even encoding/xml cannot decode correctly what was encoded:
+
+  see https://play.golang.org/p/224V_nyhMS
+  func main() {
+	fmt.Println("Hello, playground")
+	v := []interface{}{"hello", 1, true, nil, time.Now()}
+	s, err := xml.Marshal(v)
+	fmt.Printf("err: %v, \ns: %s\n", err, s)
+	var v2 []interface{}
+	err = xml.Unmarshal(s, &v2)
+	fmt.Printf("err: %v, \nv2: %v\n", err, v2)
+	type T struct {
+	    V []interface{}
+	}
+	v3 := T{V: v}
+	s, err = xml.Marshal(v3)
+	fmt.Printf("err: %v, \ns: %s\n", err, s)
+	var v4 T
+	err = xml.Unmarshal(s, &v4)
+	fmt.Printf("err: %v, \nv4: %v\n", err, v4)
+  }
+  Output:
+    err: <nil>,
+    s: <string>hello</string><int>1</int><bool>true</bool><Time>2009-11-10T23:00:00Z</Time>
+    err: <nil>,
+    v2: [<nil>]
+    err: <nil>,
+    s: <T><V>hello</V><V>1</V><V>true</V><V>2009-11-10T23:00:00Z</V></T>
+    err: <nil>,
+    v4: {[<nil> <nil> <nil> <nil>]}
