+## TOML parser and encoder for Go with reflection
+
+TOML stands for Tom's Obvious, Minimal Language. This Go package provides a
+reflection interface similar to Go's standard library `json` and `xml`
+packages. This package also supports the `encoding.TextUnmarshaler` and
+`encoding.TextMarshaler` interfaces so that you can define custom data
+representations. (There is an example of this below.)
+
+Spec: https://github.com/toml-lang/toml
+
+Compatible with TOML version
+[v0.4.0](https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.4.0.md)
+
+Documentation: https://godoc.org/github.com/BurntSushi/toml
+
+Installation:
+
+```bash
+go get github.com/BurntSushi/toml
+```
+
+Try the toml validator:
+
+```bash
+go get github.com/BurntSushi/toml/cmd/tomlv
+tomlv some-toml-file.toml
+```
+
+[![Build Status](https://travis-ci.org/BurntSushi/toml.svg?branch=master)](https://travis-ci.org/BurntSushi/toml) [![GoDoc](https://godoc.org/github.com/BurntSushi/toml?status.svg)](https://godoc.org/github.com/BurntSushi/toml)
+
+### Testing
+
+This package passes all tests in
+[toml-test](https://github.com/BurntSushi/toml-test) for both the decoder
+and the encoder.
+
+### Examples
+
+This package works similarly to how the Go standard library handles `XML`
+and `JSON`. Namely, data is loaded into Go values via reflection.
+
+For the simplest example, consider some TOML file as just a list of keys
+and values:
+
+```toml
+Age = 25
+Cats = [ "Cauchy", "Plato" ]
+Pi = 3.14
+Perfection = [ 6, 28, 496, 8128 ]
+DOB = 1987-07-05T05:45:00Z
+```
+
+Which could be defined in Go as:
+
+```go
+type Config struct {
+  Age int
+  Cats []string
+  Pi float64
+  Perfection []int
+  DOB time.Time // requires `import time`
+}
+```
+
+And then decoded with:
+
+```go
+var conf Config
+if _, err := toml.Decode(tomlData, &conf); err != nil {
+  // handle error
+}
+```
+
+You can also use struct tags if your struct field name doesn't map to a TOML
+key value directly:
+
+```toml
+some_key_NAME = "wat"
+```
+
+```go
+type TOML struct {
+  ObscureKey string `toml:"some_key_NAME"`
+}
+```
+
+### Using the `encoding.TextUnmarshaler` interface
+
+Here's an example that automatically parses duration strings into
+`time.Duration` values:
+
+```toml
+[[song]]
+name = "Thunder Road"
+duration = "4m49s"
+
+[[song]]
+name = "Stairway to Heaven"
+duration = "8m03s"
+```
+
+Which can be decoded with:
+
+```go
+type song struct {
+  Name     string
+  Duration duration
+}
+type songs struct {
+  Song []song
+}
+var favorites songs
+if _, err := toml.Decode(blob, &favorites); err != nil {
+  log.Fatal(err)
+}
+
+for _, s := range favorites.Song {
+  fmt.Printf("%s (%s)\n", s.Name, s.Duration)
+}
+```
+
+And you'll also need a `duration` type that satisfies the
+`encoding.TextUnmarshaler` interface:
+
+```go
+type duration struct {
+	time.Duration
+}
+
+func (d *duration) UnmarshalText(text []byte) error {
+	var err error
+	d.Duration, err = time.ParseDuration(string(text))
+	return err
+}
+```
+
+### More complex usage
+
+Here's an example of how to load the example from the official spec page:
+
+```toml
+# This is a TOML document. Boom.
+
+title = "TOML Example"
+
+[owner]
+name = "Tom Preston-Werner"
+organization = "GitHub"
+bio = "GitHub Cofounder & CEO\nLikes tater tots and beer."
+dob = 1979-05-27T07:32:00Z # First class dates? Why not?
+
+[database]
+server = "192.168.1.1"
+ports = [ 8001, 8001, 8002 ]
+connection_max = 5000
+enabled = true
+
+[servers]
+
+  # You can indent as you please. Tabs or spaces. TOML don't care.
+  [servers.alpha]
+  ip = "10.0.0.1"
+  dc = "eqdc10"
+
+  [servers.beta]
+  ip = "10.0.0.2"
+  dc = "eqdc10"
+
+[clients]
+data = [ ["gamma", "delta"], [1, 2] ] # just an update to make sure parsers support it
+
+# Line breaks are OK when inside arrays
+hosts = [
+  "alpha",
+  "omega"
+]
+```
+
+And the corresponding Go types are:
+
+```go
+type tomlConfig struct {
+	Title string
+	Owner ownerInfo
+	DB database `toml:"database"`
+	Servers map[string]server
+	Clients clients
+}
+
+type ownerInfo struct {
+	Name string
+	Org string `toml:"organization"`
+	Bio string
+	DOB time.Time
+}
+
+type database struct {
+	Server string
+	Ports []int
+	ConnMax int `toml:"connection_max"`
+	Enabled bool
+}
+
+type server struct {
+	IP string
+	DC string
+}
+
+type clients struct {
+	Data [][]interface{}
+	Hosts []string
+}
+```
+
+Note that a case insensitive match will be tried if an exact match can't be
+found.
+
+A working example of the above can be found in `_examples/example.{go,toml}`.

+Package toml provides facilities for decoding and encoding TOML configuration
+files via reflection. There is also support for delaying decoding with
+the Primitive type, and querying the set of keys in a TOML document with the
+MetaData type.
+
+The specification implemented: https://github.com/toml-lang/toml
+
+The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
+whether a file is a valid TOML document. It can also be used to print the
+type of each key in a TOML document.
+
+Testing
+
+There are two important types of tests used for this package. The first is
+contained inside '*_test.go' files and uses the standard Go unit testing
+framework. These tests are primarily devoted to holistically testing the
+decoder and encoder.
+
+The second type of testing is used to verify the implementation's adherence
+to the TOML specification. These tests have been factored into their own
+project: https://github.com/BurntSushi/toml-test
+
+The reason the tests are in a separate project is so that they can be used by
+any implementation of TOML. Namely, it is language agnostic.

+# Changelog
+
+## v6.13
+
+- Ring got new options called `HashReplicas` and `Hash`. It is recommended to set `HashReplicas = 1000` for better keys distribution between shards.
+- Cluster client was optimized to use much less memory when reloading cluster state.
+- PubSub.ReceiveMessage is re-worked to not use ReceiveTimeout so it does not lose data when timeout occurres. In most cases it is recommended to use PubSub.Channel instead.
+- Dialer.KeepAlive is set to 5 minutes by default.
+
+## v6.12
+
+- ClusterClient got new option called `ClusterSlots` which allows to build cluster of normal Redis Servers that don't have cluster mode enabled. See https://godoc.org/github.com/go-redis/redis#example-NewClusterClient--ManualSetup

+
+## Installation
+
+Install:
+
+```shell
+go get -u github.com/go-redis/redis
+```
+
+Import:
+
+```go
+import "github.com/go-redis/redis"
+```
+
+## Quickstart
+
+```go
+func ExampleNewClient() {
+	client := redis.NewClient(&redis.Options{
+		Addr:     "localhost:6379",
+		Password: "", // no password set
+		DB:       0,  // use default DB
+	})
+
+	pong, err := client.Ping().Result()
+	fmt.Println(pong, err)
+	// Output: PONG <nil>
+}
+
+func ExampleClient() {
+	err := client.Set("key", "value", 0).Err()
+	if err != nil {
+		panic(err)
+	}
+
+	val, err := client.Get("key").Result()
+	if err != nil {
+		panic(err)
+	}
+	fmt.Println("key", val)
+
+	val2, err := client.Get("key2").Result()
+	if err == redis.Nil {
+		fmt.Println("key2 does not exist")
+	} else if err != nil {
+		panic(err)
+	} else {
+		fmt.Println("key2", val2)
+	}
+	// Output: key value
+	// key2 does not exist
+}
+```
+
+## Howto
+
+Please go through [examples](https://godoc.org/github.com/go-redis/redis#pkg-examples) to get an idea how to use this package.
+
+## Look and feel
+
+Some corner cases:
+
+```go
+// SET key value EX 10 NX
+set, err := client.SetNX("key", "value", 10*time.Second).Result()
+
+// SORT list LIMIT 0 2 ASC
+vals, err := client.Sort("list", redis.Sort{Offset: 0, Count: 2, Order: "ASC"}).Result()
+
+// ZRANGEBYSCORE zset -inf +inf WITHSCORES LIMIT 0 2
+vals, err := client.ZRangeByScoreWithScores("zset", redis.ZRangeBy{
+	Min: "-inf",
+	Max: "+inf",
+	Offset: 0,
+	Count: 2,
+}).Result()
+
+// ZINTERSTORE out 2 zset1 zset2 WEIGHTS 2 3 AGGREGATE SUM
+vals, err := client.ZInterStore("out", redis.ZStore{Weights: []int64{2, 3}}, "zset1", "zset2").Result()
+
+// EVAL "return {KEYS[1],ARGV[1]}" 1 "key" "hello"
+vals, err := client.Eval("return {KEYS[1],ARGV[1]}", []string{"key"}, "hello").Result()
+```

+##FAQ - Frequently asked questions
+
+If your question is a good one, please ask it as a well-formatted patch to this
+repository, and we'll merge it along with the answer.
+
+###Why does this fail when added to my project in travis?
+
+This lib requires a newish version of the libvirt-dev library to compile. These
+are only available in the newer travis environment. You can add:
+
+```
+sudo: true
+dist: trusty
+install: sudo apt-get install -y libvirt-dev
+```
+
+to your `.travis.yaml` file to avoid these errors.

+# libvirt-go [![Build Status](https://travis-ci.org/libvirt/libvirt-go.svg?branch=master)](https://travis-ci.org/libvirt/libvirt-go) [![GoDoc](https://godoc.org/github.com/libvirt/libvirt-go?status.svg)](https://godoc.org/github.com/libvirt/libvirt-go)
+
+Go bindings for libvirt.
+
+Make sure to have `libvirt-dev` package (or the development files otherwise somewhere in your include path)
+
+## Version Support
+
+The libvirt go package provides API coverage for libvirt versions
+from 1.2.0 onwards, through conditional compilation of newer APIs.
+
+By default the binding will support APIs in libvirt.so, libvirt-qemu.so
+and libvirt-lxc.so. Coverage for the latter two libraries can be dropped
+from the build using build tags 'without_qemu' or 'without_lxc'
+respectively.
+
+## Development status
+
+The Go API is considered to be production ready and aims to be kept
+stable across future versions. Note, however, that the following
+changes may apply to future versions:
+
+* Existing structs can be augmented with new fields, but no existing
+  fields will be changed / removed. New fields are needed when libvirt
+  defines new typed parameters for various methods
+
+* Any method with an 'flags uint32' parameter will have its parameter
+  type changed to a specific typedef, if & when the libvirt API defines
+  constants for the flags. To avoid breakage, always pass a literal
+  '0' to any 'flags uint32' parameter, since this will auto-cast to
+  any future typedef that is introduced.
+
+## Documentation
+
+* [api documentation for the bindings](https://godoc.org/github.com/libvirt/libvirt-go)
+* [api documentation for libvirt](http://libvirt.org/html/libvirt-libvirt.html)
+
+## Contributing
+
+The libvirt project aims to add support for new APIs to libvirt-go
+as soon as they are added to the main libvirt C library. If you
+are submitting changes to the libvirt C library API, please submit
+a libvirt-go change at the same time.
+
+Bug fixes and other improvements to the libvirt-go library are
+welcome at any time. The preferred submission method is to use
+git send-email to submit patches to the libvir-list@redhat.com
+mailing list. eg. to send a single patch
+
+   git send-email --to libvir-list@redhat.com --subject-prefix "PATCH go" \
+       --smtp-server=$HOSTNAME -1
+
+Or to send all patches on the current branch, against master
+
+   git send-email --to libvir-list@redhat.com --subject-prefix "PATCH go" \
+       --smtp-server=$HOSTNAME --no-chain-reply-to --cover-letter --annotate \
+       master..
+
+Note the master GIT repository is at
+
+* http://libvirt.org/git/?p=libvirt-go.git;a=summary
+
+The following automatic read-only mirrors are available as a
+convenience to allow contributors to "fork" the repository:
+
+* https://gitlab.com/libvirt/libvirt-go
+* https://github.com/libvirt/libvirt-go
+
+While you can send pull-requests to these mirrors, they will be
+re-submitted via emai to the mailing list for review before
+being merged, unless they are trivial/obvious bug fixes.
+
+## Testing
+
+The core API unit tests are all written to use the built-in
+test driver (test:///default), so they have no interaction
+with the host OS environment.
+
+Coverage of libvirt C library APIs / constants is verified
+using automated tests. These can be run by passing the 'api'
+build tag. eg  go test -tags api
+
+For areas where the test driver lacks functionality, it is
+possible to use the QEMU or LXC drivers to exercise code.
+Such tests must be part of the 'integration_test.go' file
+though, which is only run when passing the 'integration'
+build tag. eg  go test -tags integration
+
+In order to run the unit tests, libvirtd should be configured
+to allow your user account read-write access with no passwords.
+This can be easily done using polkit config files
+
+```
+# cat > /etc/polkit-1/localauthority/50-local.d/50-libvirt.pkla  <<EOF
+[Passwordless libvirt access]
+Identity=unix-group:berrange
+Action=org.libvirt.unix.manage
+ResultAny=yes
+ResultInactive=yes
+ResultActive=yes
+EOF
+```
+
+(Replace 'berrange' with your UNIX user name).
+
+One of the integration tests also requires that libvirtd is
+listening for TCP connections on localhost, with sasl auth
+This can be setup by editing /etc/libvirt/libvirtd.conf to
+set
+
+```
+  listen_tls=0
+  listen_tcp=1
+  auth_tcp=sasl
+  listen_addr="127.0.0.1"
+```
+
+and then start libvirtd with the --listen flag (this can
+be set in /etc/sysconfig/libvirtd to make it persistent).
+
+Then create a sasl user
+
+```
+   saslpasswd2 -a libvirt user
+```
+
+and enter "pass" as the password.
+
+Alternatively a `Vagrantfile`, requiring use of virtualbox,
+is included to run the integration tests:
+
+* `cd ./vagrant`
+* `vagrant up` to provision the virtual machine
+* `vagrant ssh` to login to the virtual machine
+
+Once inside, `sudo su -` and `go test -tags integration libvirt`.

+// Helpers functions to register a Go callback function to a C
+// function. For a simple example, look at how SetErrorFunc works in
+// error.go.
+//
+// - Create a struct that will contain at least the Go callback to
+//   invoke (errorContext).
+//
+// - Create an exported Golang function whose job will be to retrieve
+//   the context and execute the callback in it
+//   (connErrCallback). Such a function should receive a callback ID
+//   and will use it to retrive the context.
+//
+// - Create a CGO function similar to the above function but with the
+//   appropriate signature to be registered as a callback in C code
+//   (connErrCallbackHelper). Notably, it will have a void* argument
+//   that should be cast to long to retrieve the callback ID. It
+//   should be just a thin wrapper to transform the opaque argument to
+//   a callback ID.
+//
+// - Create a CGO function which will be a wrapper around the C
+//   function to register the callback (virConnSetErrorFuncWrapper). Its
+//   only role is to transform a callback ID (long) to an opaque (void*)
+//   and call the C function.
+//
+// - When setting up a callback (SetErrorFunc), register the struct from first step
+//   with registerCallbackId and invoke the CGO function from the
+//   previous step with the appropriate ID.
+//
+// - When unregistering the callback, don't forget to call freecallbackId.
+//
+// If you need to associate some additional data with the connection,
+// look at saveConnectionData, getConnectionData and
+// releaseConnectionData.

+// Package libvirt provides a Go binding to the libvirt C library
+//
+// Through conditional compilation it supports libvirt versions 1.2.0 onwards.
+// This is done automatically, with no requirement to use magic Go build tags.
+// If an API was not available in the particular version of libvirt this package
+// was built against, an error will be returned with a code of ERR_NO_SUPPORT.
+// This is the same code seen if using a new libvirt library to talk to an old
+// libvirtd lacking the API, or if a hypervisor does not support a given feature,
+// so an application can easily handle all scenarios together.
+//
+// The Go binding is a fairly direct mapping of the underling C API which seeks
+// to maximise the use of the Go type system to allow strong compiler type
+// checking. The following rules describe how APIs/constants are mapped from C
+// to Go
+//
+// For structs, the 'vir' prefix and 'Ptr' suffix are removed from the name.
+// e.g. virConnectPtr in C becomes 'Connect' in Go.
+//
+// For structs which are reference counted at the C level, it is neccessary to
+// explicitly release the reference at the Go level. e.g. if a Go method returns
+// a '* Domain' struct, it is neccessary to call 'Free' on this when no longer
+// required. The use of 'defer' is recommended for this purpose
+//
+//  dom, err := conn.LookupDomainByName("myguest")
+//  if err != nil {
+//      ...
+//  }
+//  defer dom.Free()
+//
+// If multiple goroutines are using the same libvirt object struct, it may
+// not be possible to determine which goroutine should call 'Free'. In such
+// scenarios each new goroutine should call 'Ref' to obtain a private reference
+// on the underlying C struct. All goroutines can call 'Free' unconditionally
+// with the final one causing the release of the C object.
+//
+// For methods, the 'vir' prefix and object name prefix are remove from the name.
+// The C functions become methods with an object receiver. e.g.
+// 'virDomainScreenshot' in C becomes 'Screenshot' with a 'Domain *' receiver.
+//
+// For methods which accept a 'unsigned int flags' parameter in the C level,
+// the corresponding Go parameter will be a named type corresponding to the
+// C enum that defines the valid flags. For example, the ListAllDomains
+// method takes a 'flags ConnectListAllDomainsFlags' parameter. If there are
+// not currently any flags defined for a method in the C API, then the Go
+// method parameter will be declared as a "flags uint32". Callers should always
+// pass the literal integer value 0 for such parameters, without forcing any
+// specific type. This will allow compatibility with future updates to the
+// libvirt-go binding which may replace the 'uint32' type with a enum type
+// at a later date.
+//
+// For enums, the VIR_ prefix is removed from the name. The enums get a dedicated
+// type defined in Go. e.g. the VIR_NODE_SUSPEND_TARGET_MEM enum constant in C,
+// becomes NODE_SUSPEND_TARGET_MEM with a type of NodeSuspendTarget.
+//
+// Methods accepting or returning virTypedParameter arrays in C will map the
+// parameters into a Go struct. The struct will contain two fields for each
+// possible parameter. One boolean field with a suffix of 'Set' indicates whether
+// the parameter has a value set, and the other custom typed field provides the
+// parameter value. This makes it possible to distinguish a parameter with a
+// default value of '0' from a parameter which is 0 because it isn't supported by
+// the hypervisor. If the C API defines additional typed parameters, then the
+// corresponding Go struct will be extended to have further fields.
+// e.g. the GetMemoryStats method in Go (which is backed by
+// virNodeGetMemoryStats in C) will return a NodeMemoryStats struct containing
+// the typed parameter values.
+//
+//  stats, err := conn.GetMemoryParameters()
+//  if err != nil {
+//     ....
+//  }
+//  if stats.TotalSet {
+//     fmt.Printf("Total memory: %d KB", stats.Total)
+//  }
+//
+// Every method that can fail will include an 'error' object as the last return
+// value. This will be an instance of the Error struct if an error occurred. To
+// check for specific libvirt error codes, it is neccessary to cast the error.
+//
+//  err := storage_vol.Wipe(0)
+//  if err != nil {
+//     lverr, ok := err.(libvirt.Error)
+//     if ok && lverr.Code == libvirt.ERR_NO_SUPPORT {
+//         fmt.Println("Wiping storage volumes is not supported");
+//     } else {
+//         fmt.Println("Error wiping storage volume: %s", err)
+//     }
+//  }
+//
+// Example usage
+//
+// To connect to libvirt
+//
+//   import (
+//       libvirt "github.com/libvirt/libvirt-go"
+//   )
+//   conn, err := libvirt.NewConnect("qemu:///system")
+//   if err != nil {
+//       ...
+//   }
+//   defer conn.Close()
+//
+//   doms, err := conn.ListAllDomains(libvirt.CONNECT_LIST_DOMAINS_ACTIVE)
+//   if err != nil {
+//       ...
+//   }
+//
+//   fmt.Printf("%d running domains:\n", len(doms))
+//   for _, dom := range doms {
+//       name, err := dom.GetName()
+//       if err == nil {

+
+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!

+
+
+## 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.

+## Prequisites
+
+1. Go: [https://golang.org/dl/](https://golang.org/dl/)
+1. Golint `go get -u -v github.com/golang/lint/golint`
+
+## Contributing
+
+The workflow is pretty standard:
+
+1. Fork github.com/streadway/amqp
+1. Add the pre-commit hook: `ln -s ../../pre-commit .git/hooks/pre-commit`
+1. Create your feature branch (`git checkout -b my-new-feature`)
+1. Run integration tests (see below)
+1. **Implement tests**
+1. Implement fixs
+1. Commit your changes (`git commit -am 'Add some feature'`)
+1. Push to a branch (`git push -u origin my-new-feature`)
+1. Submit a pull request
+
+## Running Tests
+
+The test suite assumes that:
+
+ * A RabbitMQ node is running on localhost with all defaults: [https://www.rabbitmq.com/download.html](https://www.rabbitmq.com/download.html)
+ * `AMQP_URL` is exported to `amqp://guest:guest@127.0.0.1:5672/`
+
+### Integration Tests
+
+After starting a local RabbitMQ, run integration tests with the following:
+
+    env AMQP_URL=amqp://guest:guest@127.0.0.1:5672/ go test -v -cpu 2 -tags integration -race
+
+All integration tests should use the `integrationConnection(...)` test
+helpers defined in `integration_test.go` to setup the integration environment
+and logging.

+# Go RabbitMQ Client Library
+
+This is an AMQP 0.9.1 client with RabbitMQ extensions in Go.
+
+## Project Maturity
+
+This project has been used in production systems for many years. It is reasonably mature
+and feature complete, and as of November 2016 has [a team of maintainers](https://github.com/streadway/amqp/issues/215).
+
+Future API changes are unlikely but possible. They will be discussed on [Github
+issues](https://github.com/streadway/amqp/issues) along with any bugs or
+enhancements.
+
+## Supported Go Versions
+
+This library supports two most recent Go release series, currently 1.8 and 1.9.
+
+
+## Supported RabbitMQ Versions
+
+This project supports RabbitMQ versions starting with `2.0` but primarily tested
+against reasonably recent `3.x` releases. Some features and behaviours may be
+server version-specific.
+
+## Goals
+
+Provide a functional interface that closely represents the AMQP 0.9.1 model
+targeted to RabbitMQ as a server.  This includes the minimum necessary to
+interact the semantics of the protocol.
+
+## Non-goals
+
+Things not intended to be supported.
+
+  * Auto reconnect and re-synchronization of client and server topologies.
+    * Reconnection would require understanding the error paths when the
+      topology cannot be declared on reconnect.  This would require a new set
+      of types and code paths that are best suited at the call-site of this
+      package.  AMQP has a dynamic topology that needs all peers to agree. If
+      this doesn't happen, the behavior is undefined.  Instead of producing a
+      possible interface with undefined behavior, this package is designed to
+      be simple for the caller to implement the necessary connection-time
+      topology declaration so that reconnection is trivial and encapsulated in
+      the caller's application code.
+  * AMQP Protocol negotiation for forward or backward compatibility.
+    * 0.9.1 is stable and widely deployed.  Versions 0.10 and 1.0 are divergent
+      specifications that change the semantics and wire format of the protocol.
+      We will accept patches for other protocol support but have no plans for
+      implementation ourselves.
+  * Anything other than PLAIN and EXTERNAL authentication mechanisms.
+    * Keeping the mechanisms interface modular makes it possible to extend
+      outside of this package.  If other mechanisms prove to be popular, then
+      we would accept patches to include them in this package.
+
+## Usage
+
+See the 'examples' subdirectory for simple producers and consumers executables.
+If you have a use-case in mind which isn't well-represented by the examples,
+please file an issue.
+
+## Documentation
+
+Use [Godoc documentation](http://godoc.org/github.com/streadway/amqp) for
+reference and usage.
+
+[RabbitMQ tutorials in
+Go](https://github.com/rabbitmq/rabbitmq-tutorials/tree/master/go) are also
+available.
+
+## Contributing
+
+Pull requests are very much welcomed.  Create your pull request on a non-master
+branch, make sure a test or example is included that covers your change and
+your commits represent coherent changes that include a reason for the change.
+
+To run the integration tests, make sure you have RabbitMQ running on any host,
+export the environment variable `AMQP_URL=amqp://host/` and run `go test -tags
+integration`.  TravisCI will also run the integration tests.
+
+Thanks to the [community of contributors](https://github.com/streadway/amqp/graphs/contributors).

+
+Errors returned from this method will close the channel.
+
+Exchange names starting with "amq." are reserved for pre-declared and
+standardized exchanges. The client MAY declare an exchange starting with
+"amq." if the passive option is set, or the exchange already exists.  Names can
+consist of a non-empty sequence of letters, digits, hyphen, underscore,
+period, or colon.
+
+Each exchange belongs to one of a set of exchange kinds/types implemented by
+the server. The exchange types define the functionality of the exchange - i.e.
+how messages are routed through it. Once an exchange is declared, its type
+cannot be changed.  The common types are "direct", "fanout", "topic" and
+"headers".
+
+Durable and Non-Auto-Deleted exchanges will survive server restarts and remain
+declared when there are no remaining bindings.  This is the best lifetime for
+long-lived exchange configurations like stable routes and default exchanges.
+
+Non-Durable and Auto-Deleted exchanges will be deleted when there are no
+remaining bindings and not restored on server restart.  This lifetime is
+useful for temporary topologies that should not pollute the virtual host on
+failure or after the consumers have completed.
+
+Non-Durable and Non-Auto-deleted exchanges will remain as long as the server is
+running including when there are no remaining bindings.  This is useful for
+temporary topologies that may have long delays between bindings.
+
+Durable and Auto-Deleted exchanges will survive server restarts and will be
+removed before and after server restarts when there are no remaining bindings.
+These exchanges are useful for robust temporary topologies or when you require
+binding durable queues to auto-deleted exchanges.
+
+Note: RabbitMQ declares the default exchange types like 'amq.fanout' as
+durable, so queues that bind to these pre-declared exchanges must also be
+durable.
+
+Exchanges declared as `internal` do not accept accept publishings. Internal
+exchanges are useful when you wish to implement inter-exchange topologies
+that should not be exposed to users of the broker.
+
+When noWait is true, declare without waiting for a confirmation from the server.

+Package amqp is an AMQP 0.9.1 client with RabbitMQ extensions
+
+Understand the AMQP 0.9.1 messaging model by reviewing these links first. Much
+of the terminology in this library directly relates to AMQP concepts.
+
+  Resources
+
+  http://www.rabbitmq.com/tutorials/amqp-concepts.html
+  http://www.rabbitmq.com/getstarted.html
+  http://www.rabbitmq.com/amqp-0-9-1-reference.html
+
+Design
+
+Most other broker clients publish to queues, but in AMQP, clients publish
+Exchanges instead.  AMQP is programmable, meaning that both the producers and
+consumers agree on the configuration of the broker, instead requiring an
+operator or system configuration that declares the logical topology in the
+broker.  The routing between producers and consumer queues is via Bindings.
+These bindings form the logical topology of the broker.
+
+In this library, a message sent from publisher is called a "Publishing" and a
+message received to a consumer is called a "Delivery".  The fields of
+Publishings and Deliveries are close but not exact mappings to the underlying
+wire format to maintain stronger types.  Many other libraries will combine
+message properties with message headers.  In this library, the message well
+known properties are strongly typed fields on the Publishings and Deliveries,
+whereas the user defined headers are in the Headers field.
+
+The method naming closely matches the protocol's method name with positional
+parameters mapping to named protocol message fields.  The motivation here is to
+present a comprehensive view over all possible interactions with the server.
+
+Generally, methods that map to protocol methods of the "basic" class will be
+elided in this interface, and "select" methods of various channel mode selectors
+will be elided for example Channel.Confirm and Channel.Tx.
+
+The library is intentionally designed to be synchronous, where responses for
+each protocol message are required to be received in an RPC manner.  Some
+methods have a noWait parameter like Channel.QueueDeclare, and some methods are
+asynchronous like Channel.Publish.  The error values should still be checked for
+these methods as they will indicate IO failures like when the underlying
+connection closes.
+
+Asynchronous Events
+
+Clients of this library may be interested in receiving some of the protocol
+messages other than Deliveries like basic.ack methods while a channel is in
+confirm mode.
+
+The Notify* methods with Connection and Channel receivers model the pattern of
+asynchronous events like closes due to exceptions, or messages that are sent out
+of band from an RPC call like basic.ack or basic.flow.
+
+Any asynchronous events, including Deliveries and Publishings must always have
+a receiver until the corresponding chans are closed.  Without asynchronous
+receivers, the sychronous methods will block.
+
+Use Case
+
+It's important as a client to an AMQP topology to ensure the state of the
+broker matches your expectations.  For both publish and consume use cases,
+make sure you declare the queues, exchanges and bindings you expect to exist
+prior to calling Channel.Publish or Channel.Consume.
+
+  // Connections start with amqp.Dial() typically from a command line argument
+  // or environment variable.
+  connection, err := amqp.Dial(os.Getenv("AMQP_URL"))
+
+  // To cleanly shutdown by flushing kernel buffers, make sure to close and
+  // wait for the response.
+  defer connection.Close()
+
+  // Most operations happen on a channel.  If any error is returned on a
+  // channel, the channel will no longer be valid, throw it away and try with
+  // a different channel.  If you use many channels, it's useful for the
+  // server to
+  channel, err := connection.Channel()
+
+  // Declare your topology here, if it doesn't exist, it will be created, if
+  // it existed already and is not what you expect, then that's considered an
+  // error.
+
+  // Use your connection on this topology with either Publish or Consume, or
+  // inspect your queues with QueueInspect.  It's unwise to mix Publish and
+  // Consume to let TCP do its job well.
+
+SSL/TLS - Secure connections
+
+When Dial encounters an amqps:// scheme, it will use the zero value of a
+tls.Config.  This will only perform server certificate and host verification.
+
+Use DialTLS when you wish to provide a client certificate (recommended),
+include a private certificate authority's certificate in the cert chain for
+server validity, or run insecure by not verifying the server certificate dial
+your own connection.  DialTLS will use the provided tls.Config when it
+encounters an amqps:// scheme and will dial a plain connection when it
+encounters an amqp:// scheme.
+
+SSL/TLS in RabbitMQ is documented here: http://www.rabbitmq.com/ssl.html

+Reads a frame from an input stream and returns an interface that can be cast into
+one of the following:
+
+   methodFrame
+   PropertiesFrame
+   bodyFrame
+   heartbeatFrame
+
+2.3.5  frame Details
+
+All frames consist of a header (7 octets), a payload of arbitrary size, and a
+'frame-end' octet that detects malformed frames:
+
+  0      1         3             7                  size+7 size+8
+  +------+---------+-------------+  +------------+  +-----------+
+  | type | channel |     size    |  |  payload   |  | frame-end |
+  +------+---------+-------------+  +------------+  +-----------+
+   octet   short         long         size octets       octet
+
+To read a frame, we:
+  1. Read the header and check the frame type and channel.
+	2. Depending on the frame type, we read the payload and process it.
+  3. Read the frame end octet.
+
+In realistic implementations where performance is a concern, we would use
+“read-ahead buffering” or
+
+“gathering reads” to avoid doing three separate system calls to read a frame.

+# bytebufferpool
+
+An implementation of a pool of byte buffers with anti-memory-waste protection.
+
+The pool may waste limited amount of memory due to fragmentation.
+This amount equals to the maximum total size of the byte buffers
+in concurrent use.
+
+# Benchmark results
+Currently bytebufferpool is fastest and most effective buffer pool written in Go.
+
+You can find results [here](https://omgnull.github.io/go-benchmark/buffer/).

+fasttemplate
+============
+
+Simple and fast template engine for Go.
+
+Fasttemplate peforms only a single task - it substitutes template placeholders
+with user-defined values. At high speed :)
+
+Take a look at [quicktemplate](https://github.com/valyala/quicktemplate) if you  need fast yet powerful html template engine.
+
+*Please note that fasttemplate doesn't do any escaping on template values
+unlike [html/template](http://golang.org/pkg/html/template/) do. So values
+must be properly escaped before passing them to fasttemplate.*
+
+Fasttemplate is faster than [text/template](http://golang.org/pkg/text/template/),
+[strings.Replace](http://golang.org/pkg/strings/#Replace),
+[strings.Replacer](http://golang.org/pkg/strings/#Replacer)
+and [fmt.Fprintf](https://golang.org/pkg/fmt/#Fprintf) on placeholders' substitution.
+
+Below are benchmark results comparing fasttemplate performance to text/template,
+strings.Replace, strings.Replacer and fmt.Fprintf:
+
+```
+$ go test -bench=. -benchmem
+PASS
+BenchmarkFmtFprintf-4                   	 2000000	       790 ns/op	       0 B/op	       0 allocs/op

+Docs
+====
+
+See http://godoc.org/github.com/valyala/fasttemplate .
+
+
+Usage
+=====
+
+```go
+	template := "http://{{host}}/?q={{query}}&foo={{bar}}{{bar}}"
+	t := fasttemplate.New(template, "{{", "}}")
+	s := t.ExecuteString(map[string]interface{}{
+		"host":  "google.com",
+		"query": url.QueryEscape("hello=world"),
+		"bar":   "foobar",
+	})
+	fmt.Printf("%s", s)
+
+	// Output:
+	// http://google.com/?q=hello%3Dworld&foo=foobarfoobar
+```
+
+
+Advanced usage
+==============
+
+```go
+	template := "Hello, [user]! You won [prize]!!! [foobar]"
+	t, err := fasttemplate.NewTemplate(template, "[", "]")
+	if err != nil {
+		log.Fatalf("unexpected error when parsing template: %s", err)
+	}
+	s := t.ExecuteFuncString(func(w io.Writer, tag string) (int, error) {
+		switch tag {
+		case "user":
+			return w.Write([]byte("John"))
+		case "prize":
+			return w.Write([]byte("$100500"))
+		default:
+			return w.Write([]byte(fmt.Sprintf("[unknown tag %q]", tag)))
+		}
+	})
+	fmt.Printf("%s", s)
+
+	// Output:
+	// Hello, John! You won $100500!!! [unknown tag "foobar"]
+```
