----
-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)
-}
-```

-## 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)

-  // 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

-	FlagRemoveDotSegments   // http://host/path/./a/b/../c -> http://host/path/a/c
-
-	// Unsafe normalizations
-	FlagRemoveDirectoryIndex   // http://host/path/index.html -> http://host/path/

-	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

-	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

-	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})$`.

-# 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).

-// Package clientv3 implements the official Go etcd client for v3.
-//
-// Create client using `clientv3.New`:
-//
-//	// expect dial time-out on ipv4 blackhole
-//	_, err := clientv3.New(clientv3.Config{
-//		Endpoints:   []string{"http://254.0.0.1:12345"},
-//		DialTimeout: 2 * time.Second
-//	})
-//
-//	// etcd clientv3 >= v3.2.10, grpc/grpc-go >= v1.7.3
-//	if err == context.DeadlineExceeded {
-//		// handle errors
-//	}
-//
-//	// etcd clientv3 <= v3.2.9, grpc/grpc-go <= v1.2.1
-//	if err == grpc.ErrClientConnTimeout {
-//		// handle errors
-//	}
-//
-//	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()
-//
-// Make sure to close the client after using it. If the client is not closed, the
-// connection will have leaky goroutines.
-//
-// To specify a client request timeout, wrap the context with context.WithTimeout:
-//
-//	ctx, cancel := context.WithTimeout(context.Background(), timeout)
-//	resp, err := kvc.Put(ctx, "sample_key", "sample_value")
-//	cancel()
-//	if err != nil {
-//	    // handle error!
-//	}
-//	// use the response
-//
-// The Client has internal state (watchers and leases), so Clients should be reused instead of created as needed.
-// Clients are safe for concurrent use by multiple goroutines.
-//
-// etcd client returns 3 types of errors:
-//
-//  1. context error: canceled or deadline exceeded.
-//  2. gRPC status error: e.g. when clock drifts in server-side before client's context deadline exceeded.
-//  3. gRPC error: see https://github.com/coreos/etcd/blob/master/etcdserver/api/v3rpc/rpctypes/error.go
-//
-// Here is the example code to handle client errors:
-//
-//	resp, err := kvc.Put(ctx, "", "")
-//	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 ev, ok := status.FromError(err); ok {
-//			code := ev.Code()
-//			if code == codes.DeadlineExceeded {
-//				// server-side context might have timed-out first (due to clock skew)
-//				// while original client-side context is not timed-out yet
-//			}
-//		} else if verr, ok := err.(*v3rpc.ErrEmptyKey); ok {
-//			// process (verr.Errors)
-//		} else {
-//			// bad cluster endpoints, which are not etcd servers
-//		}
-//	}
-//
-//	go func() { cli.Close() }()
-//	_, err := kvc.Get(ctx, "a")
-//	if err != nil {
-//		if err == context.Canceled {
-//			// grpc balancer calls 'Get' with an inflight client.Close
-//		} else if err == grpc.ErrClientConnClosing {
-//			// grpc balancer calls 'Get' after client.Close.
-//		}
-//	}

-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.

-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.
