+# TOML Validator
+
+If Go is installed, it's simple to try it out:
+
+```bash
+go get github.com/BurntSushi/toml/cmd/tomlv
+tomlv some-toml-file.toml
+```
+
+You can see the types of every key in a TOML file with:
+
+```bash
+tomlv -types some-toml-file.toml
+```
+
+At the moment, only one error message is reported at a time. Error messages
+include line numbers. No output means that the files given are valid TOML, or 
+there is a bug in `tomlv`.
+
+Compatible with TOML version
+[v0.1.0](https://github.com/mojombo/toml/blob/master/versions/toml-v0.1.0.md)

+[![Build Status](https://img.shields.io/travis/davecgh/go-spew.svg)]
+(https://travis-ci.org/davecgh/go-spew) [![ISC License]
+(http://img.shields.io/badge/license-ISC-blue.svg)](http://copyfree.org) [![Coverage Status]
+(https://img.shields.io/coveralls/davecgh/go-spew.svg)]
+(https://coveralls.io/r/davecgh/go-spew?branch=master)
+
+
+Go-spew implements a deep pretty printer for Go data structures to aid in
+debugging.  A comprehensive suite of tests with 100% test coverage is provided
+to ensure proper functionality.  See `test_coverage.txt` for the gocov coverage
+report.  Go-spew is licensed under the liberal ISC license, so it may be used in
+open source or commercial projects.
+
+If you're interested in reading about how this package came to life and some
+of the challenges involved in providing a deep pretty printer, there is a blog
+post about it
+[here](https://web.archive.org/web/20160304013555/https://blog.cyphertite.com/go-spew-a-journey-into-dumping-go-data-structures/).
+
+## Documentation
+
+[![GoDoc](https://img.shields.io/badge/godoc-reference-blue.svg)]
+(http://godoc.org/github.com/davecgh/go-spew/spew)
+
+Full `go doc` style documentation for the project can be viewed online without
+installing this package by using the excellent GoDoc site here:
+http://godoc.org/github.com/davecgh/go-spew/spew
+
+You can also view the documentation locally once the package is installed with
+the `godoc` tool by running `godoc -http=":6060"` and pointing your browser to
+http://localhost:6060/pkg/github.com/davecgh/go-spew/spew
+
+## Installation
+
+```bash
+$ go get -u github.com/davecgh/go-spew/spew
+```
+
+## Quick Start
+
+Add this import line to the file you're working in:
+
+```Go
+import "github.com/davecgh/go-spew/spew"
+```
+
+To dump a variable with full newlines, indentation, type, and pointer
+information use Dump, Fdump, or Sdump:
+
+```Go
+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): 
+
+```Go
+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)
+```
+
+## Debugging a Web Application Example
+
+Here is an example of how you can use `spew.Sdump()` to help debug a web application. Please be sure to wrap your output using the `html.EscapeString()` function for safety reasons. You should also only use this debugging technique in a development environment, never in production.
+
+```Go
+package main
+
+import (
+    "fmt"
+    "html"
+    "net/http"
+
+    "github.com/davecgh/go-spew/spew"
+)
+
+func handler(w http.ResponseWriter, r *http.Request) {
+    w.Header().Set("Content-Type", "text/html")
+    fmt.Fprintf(w, "Hi there, %s!", r.URL.Path[1:])
+    fmt.Fprintf(w, "<!--\n" + html.EscapeString(spew.Sdump(w)) + "\n-->")
+}
+
+func main() {
+    http.HandleFunc("/", handler)
+    http.ListenAndServe(":8080", nil)
+}
+```
+
+## Sample Dump Output
+
+```
+(main.Foo) {
+ unexportedField: (*main.Bar)(0xf84002e210)({
+  flag: (main.Flag) flagTwo,
+  data: (uintptr) <nil>
+ }),
+ ExportedField: (map[interface {}]interface {}) {
+  (string) "one": (bool) true
+ }
+}
+([]uint8) {
+ 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|
+}
+```
+
+## 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>}
+```
+
+## 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.
+
+```
+* 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.  This option
+	relies on access to the unsafe package, so it will not have any effect when
+	running in environments without access to the unsafe package such as Google
+	App Engine or with the "safe" build tag specified.
+	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
+	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.
+
+```
+
+## Unsafe Package Dependency
+
+This package relies on the unsafe package to perform some of the more advanced
+features, however it also supports a "limited" mode which allows it to work in
+environments where the unsafe package is not available.  By default, it will
+operate in this mode on Google App Engine and when compiled with GopherJS.  The
+"safe" build tag may also be specified to force the package to build without
+using the unsafe package.

+- Grab the code from the repository and install the proto package.
+  The simplest way is to run `go get -u github.com/golang/protobuf/{proto,protoc-gen-go}`.
+  The compiler plugin, protoc-gen-go, will be installed in $GOBIN,
+  defaulting to $GOPATH/bin.  It must be in your $PATH for the protocol
+  compiler, protoc, to find it.
+
+This software has two parts: a 'protocol compiler plugin' that
+generates Go source files that, once compiled, can access and manage
+protocol buffers; and a library that implements run-time support for
+encoding (marshaling), decoding (unmarshaling), and accessing protocol
+buffers.
+
+There is support for gRPC in Go using protocol buffers.
+See the note at the bottom of this file for details.
+
+There are no insertion points in the plugin.
+
+GoGoProtobuf provides extensions for protocol buffers and GoProtobuf
+see http://github.com/gogo/protobuf/gogoproto/doc.go
+
+## Using protocol buffers with Go ##
+
+Once the software is installed, there are two steps to using it.
+First you must compile the protocol buffer definitions and then import
+them, with the support library, into your program.
+
+To compile the protocol buffer definition, run protoc with the --gogo_out
+parameter set to the directory you want to output the Go code to.
+
+	protoc --gogo_out=. *.proto
+
+The generated files will be suffixed .pb.go.  See the Test code below
+for an example using such a file.
+
+The package comment for the proto library contains text describing
+the interface provided in Go for protocol buffers. Here is an edited
+version.
+
+If you are using any gogo.proto extensions you will need to specify the
+proto_path to include the descriptor.proto and gogo.proto.
+gogo.proto is located in github.com/gogo/protobuf/gogoproto
+This should be fine, since your import is the same.
+descriptor.proto is located in either github.com/gogo/protobuf/protobuf
+or code.google.com/p/protobuf/trunk/src/
+Its import is google/protobuf/descriptor.proto so it might need some help.
+
+	protoc --gogo_out=. -I=.:github.com/gogo/protobuf/protobuf *.proto
+
+==========
+
+The proto package 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.
+	Helpers for getting values are superseded by the
+	GetFoo methods and their use is deprecated.
+		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 with the enum's type name. Enum types have
+	a String method, and a Enum method to assist in message construction.
+  - Nested 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.
+  - Getters are only generated for message and oneof fields.
+  - Enum types do not get an Enum method.
+
+Consider file test.proto, containing
+
+```proto
+	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;
+	  }
+	}
+```
+
+To create and play with a Test object from the example package,
+
+```go
+	package main
+
+	import (
+		"log"
+
+		"github.com/gogo/protobuf/proto"
+		"path/to/example"
+	)
+
+	func main() {
+		test := &example.Test {
+			Label: proto.String("hello"),
+			Type:  proto.Int32(17),
+			Reps:  []int64{1, 2, 3},
+			Optionalgroup: &example.Test_OptionalGroup {
+				RequiredField: proto.String("good bye"),
+			},
+		}
+		data, err := proto.Marshal(test)
+		if err != nil {
+			log.Fatal("marshaling error: ", err)
+		}
+		newTest := &example.Test{}
+		err = proto.Unmarshal(data, newTest)
+		if err != nil {
+			log.Fatal("unmarshaling error: ", err)
+		}
+		// Now test and newTest contain the same data.
+		if test.GetLabel() != newTest.GetLabel() {
+			log.Fatalf("data mismatch %q != %q", test.GetLabel(), newTest.GetLabel())
+		}
+		// etc.
+	}
+```
+
+
+## Parameters ##
+
+To pass extra parameters to the plugin, use a comma-separated
+parameter list separated from the output directory by a colon:
+
+
+	protoc --gogo_out=plugins=grpc,import_path=mypackage:. *.proto
+
+
+- `import_prefix=xxx` - a prefix that is added onto the beginning of
+  all imports. Useful for things like generating protos in a
+  subdirectory, or regenerating vendored protobufs in-place.
+- `import_path=foo/bar` - used as the package if no input files
+  declare `go_package`. If it contains slashes, everything up to the
+  rightmost slash is ignored.
+- `plugins=plugin1+plugin2` - specifies the list of sub-plugins to
+  load. The only plugin in this repo is `grpc`.
+- `Mfoo/bar.proto=quux/shme` - declares that foo/bar.proto is
+  associated with Go package quux/shme.  This is subject to the
+  import_prefix parameter.
+
+## gRPC Support ##
+
+If a proto file specifies RPC services, protoc-gen-go can be instructed to
+generate code compatible with gRPC (http://www.grpc.io/). To do this, pass
+the `plugins` parameter to protoc-gen-go; the usual way is to insert it into
+the --go_out argument to protoc:
+
+	protoc --gogo_out=plugins=grpc:. *.proto
+
+## Compatibility ##
+
+The library and the generated code are expected to be stable over time.
+However, we reserve the right to make breaking changes without notice for the
+following reasons:
+
+- Security. A security issue in the specification or implementation may come to
+  light whose resolution requires breaking compatibility. We reserve the right
+  to address such security issues.
+- Unspecified behavior.  There are some aspects of the Protocol Buffers
+  specification that are undefined.  Programs that depend on such unspecified
+  behavior may break in future releases.
+- Specification errors or changes. If it becomes necessary to address an
+  inconsistency, incompleteness, or change in the Protocol Buffers
+  specification, resolving the issue could affect the meaning or legality of
+  existing programs.  We reserve the right to address such issues, including
+  updating the implementations.
+- Bugs.  If the library has a bug that violates the specification, a program
+  that depends on the buggy behavior may break if the bug is fixed.  We reserve
+  the right to fix such bugs.
+- Adding methods or fields to generated structs.  These may conflict with field
+  names that already exist in a schema, causing applications to break.  When the
+  code generator encounters a field in the schema that would collide with a
+  generated field or method name, the code generator will append an underscore
+  to the generated field or method name.
+- Adding, removing, or changing methods or fields in generated structs that
+  start with `XXX`.  These parts of the generated code are exported out of
+  necessity, but should not be considered part of the public API.
+- Adding, removing, or changing unexported symbols in generated code.
+
+Any breaking changes outside of these will be announced 6 months in advance to
+protobuf@googlegroups.com.
+
+You should, whenever possible, use generated code created by the `protoc-gen-go`
+tool built at the same commit as the `proto` package.  The `proto` package
+declares package-level constants in the form `ProtoPackageIsVersionX`.
+Application code and generated code may depend on one of these constants to
+ensure that compilation will fail if the available version of the proto library
+is too old.  Whenever we make a change to the generated code that requires newer
+library support, in the same commit we will increment the version number of the
+generated code and declare a new package-level constant whose name incorporates
+the latest version number.  Removing a compatibility constant is considered a
+breaking change and would be subject to the announcement policy stated above.
+
+## Plugins ##
+
+The `protoc-gen-go/generator` package exposes a plugin interface,
+which is used by the gRPC code generation. This interface is not
+supported and is subject to incompatible changes without notice.

+
+[![Build Status](https://travis-ci.org/gogo/protobuf.svg?branch=master)](https://travis-ci.org/gogo/protobuf)
+
+gogoprotobuf is a fork of <a href="https://github.com/golang/protobuf">golang/protobuf</a> with extra code generation features.
+
+This code generation is used to achieve:
+  
+  - fast marshalling and unmarshalling
+  - more canonical Go structures
+  - goprotobuf compatibility
+  - less typing by optionally generating extra helper code
+  - peace of mind by optionally generating test and benchmark code
+  - other serialization formats
+
+Keeping track of how up to date gogoprotobuf is relative to golang/protobuf is done in this

+
+## Getting Started 
+
+There are several ways to use gogoprotobuf, but for all you need to install go and protoc.
+After that you can choose:
+ 
+  - Speed
+  - More Speed and more generated code
+  - Most Speed and most customization
+
+### Installation
+
+To install it, you must first have Go (at least version 1.3.3) installed (see [http://golang.org/doc/install](http://golang.org/doc/install)).  Go 1.5.4, 1.6.3 and 1.7.1 are continuously tested.
+
+Next, install the standard protocol buffer implementation from [https://github.com/google/protobuf](https://github.com/google/protobuf).
+Most versions from 2.3.1 should not give any problems, but 2.5.0, 2.6.1 and 3.0.2 are continuously tested.
+
+### Speed
+
+Install the protoc-gen-gofast binary
+
+    go get github.com/gogo/protobuf/protoc-gen-gofast
+
+Use it to generate faster marshaling and unmarshaling go code for your protocol buffers.
+
+    protoc --gofast_out=. myproto.proto
+
+This does not allow you to use any of the other gogoprotobuf [extensions](https://github.com/gogo/protobuf/blob/master/extensions.md).
+
+### More Speed and more generated code
+
+Fields without pointers cause less time in the garbage collector.
+More code generation results in more convenient methods.
+
+Other binaries are also included:
+
+    protoc-gen-gogofast (same as gofast, but imports gogoprotobuf)
+    protoc-gen-gogofaster (same as gogofast, without XXX_unrecognized, less pointer fields)
+    protoc-gen-gogoslick (same as gogofaster, but with generated string, gostring and equal methods)
+
+Installing any of these binaries is easy.  Simply run:
+
+    go get github.com/gogo/protobuf/proto
+    go get github.com/gogo/protobuf/{binary}
+    go get github.com/gogo/protobuf/gogoproto
+
+These binaries allow you to using gogoprotobuf [extensions](https://github.com/gogo/protobuf/blob/master/extensions.md).
+
+### Most Speed and most customization
+
+Customizing the fields of the messages to be the fields that you actually want to use removes the need to copy between the structs you use and structs you use to serialize.
+gogoprotobuf also offers more serialization formats and generation of tests and even more methods.
+
+Please visit the [extensions](https://github.com/gogo/protobuf/blob/master/extensions.md) page for more documentation.
+
+Install protoc-gen-gogo:
+
+    go get github.com/gogo/protobuf/proto
+    go get github.com/gogo/protobuf/jsonpb
+    go get github.com/gogo/protobuf/protoc-gen-gogo
+    go get github.com/gogo/protobuf/gogoproto
+
+## GRPC
+
+It works the same as golang/protobuf, simply specify the plugin.
+Here is an example using gofast:
+
+    protoc --gofast_out=plugins=grpc:. my.proto

+// You can either run the tests in two different ways:

+//   1. in-process (using the interface in conformance_test.h).

+//   2. as a sub-process communicating over a pipe.  Information about how to

+// Pros/cons of the two approaches:

+//   - running as a sub-process is much simpler for languages other than C/C++.
+//
+//   - running as a sub-process may be more tricky in unusual environments like
+//     iOS apps, where fork/stdin/stdout are not available.

+# gogoprotobuf Extensions
+
+Here is an [example.proto](https://github.com/gogo/protobuf/blob/master/test/example/example.proto) which uses most of the gogoprotobuf code generation plugins.
+
+Please also look at the example [Makefile](https://github.com/gogo/protobuf/blob/master/test/example/Makefile) which shows how to specify the `descriptor.proto` and `gogo.proto` in your proto_path
+
+The documentation at [http://godoc.org/github.com/gogo/protobuf/gogoproto](http://godoc.org/github.com/gogo/protobuf/gogoproto) describes the extensions made to goprotobuf in more detail.
+
+Also see [http://godoc.org/github.com/gogo/protobuf/plugin/](http://godoc.org/github.com/gogo/protobuf/plugin/) for documentation of each of the extensions which have their own plugins.
+
+# Fast Marshalling and Unmarshalling
+
+Generating a `Marshal`, `MarshalTo`, `Size` (or `ProtoSize`) and `Unmarshal` method for a struct results in faster marshalling and unmarshalling than when using reflect.
+
+See [BenchComparison](https://github.com/gogo/protobuf/blob/master/bench.md) for a comparison between reflect and generated code used for marshalling and unmarshalling.

+# More Canonical Go Structures
+
+Lots of times 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 new struct.
+
+`gogoprotobuf` tries to fix these problems with the nullable, embed, customtype, customname, casttype, castkey and castvalue field extensions.
+

+
+`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.` 
+
+`Warning about customtype: It is your responsibility to test all cases of your marshaling, unmarshaling and size methods implemented for your custom type.`
+
+Issues with customtype include:
+  * <a href="https://github.com/gogo/protobuf/issues/199">A Bytes method is not allowed.<a/>
+  * <a href="https://github.com/gogo/protobuf/issues/132">Defining a customtype as a fake proto message is broken.</a>

+
+# Goprotobuf Compatibility 
+
+Gogoprotobuf is compatible with Goprotobuf, because it is compatible with protocol buffers (see the section on tests below).
+
+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.

+Other serialization formats like xml and json typically use reflect to marshal and unmarshal structured data.  Manipulating these structs into something other than the default Go requires editing tags.  The following extensions provide ways of editing these tags for the generated protobuf structs.
+
+<table>
+<tr><td><a href="https://github.com/gogo/protobuf/blob/master/test/tags/tags.proto">jsontag</a> (beta) </td><td> Field </td><td> string </td><td> if set, the json tag value between the double quotes is replaced with this string </td><td> fieldname </td></tr>
+<tr><td><a href="https://github.com/gogo/protobuf/blob/master/test/tags/tags.proto">moretags</a> (beta) </td><td> Field </td><td> string </td><td> if set, this string is appended to the tag string </td><td> empty </td></tr>
+</table>
+
+<a href="https://groups.google.com/forum/#!topic/gogoprotobuf/xmFnqAS6MIc">Here is a longer explanation of jsontag and moretags</a>
+
+# File Options 
+
+Each of the boolean message and enum extensions also have a file extension:
+
+  * `marshaler_all`
+  * `sizer_all`
+  * `protosizer_all`
+  * `unmarshaler_all`
+  * `unsafe_marshaler_all`
+  * `unsafe_unmarshaler_all`
+  * `stable_marshaler_all`
+  * `goproto_enum_prefix_all`
+  * `goproto_getters_all`
+  * `goproto_stringer_all`
+  * `goproto_enum_stringer_all`
+  * `goproto_extensions_map_all`
+  * `goproto_unrecognized_all`
+  * `gostring_all`
+  * `onlyone_all`
+  * `equal_all`
+  * `compare_all`
+  * `verbose_equal_all`
+  * `stringer_all`
+  * `enum_stringer_all`
+  * `face_all`
+  * `description_all`
+  * `populate_all`
+  * `testgen_all`
+  * `benchgen_all`
+
+Each of these are the same as their Message Option counterparts, except they apply to all messages in the file.  Their Message option counterparts can also be used to overwrite their effect.
+
+# Tests
+
+  * The normal barrage of tests are run with: `make tests` 
+  * A few weird tests: `make testall`
+  * Tests for compatibility with [golang/protobuf](https://github.com/golang/protobuf) are handled by a different project [harmonytests](https://github.com/gogo/harmonytests), since it requires goprotobuf.
+  * Cross version tests are made with [Travis CI](https://travis-ci.org/gogo/protobuf).
+  * GRPC Tests are also handled by a different project [grpctests](https://github.com/gogo/grpctests), since it depends on a lot of grpc libraries.
+  * Thanks to [go-fuzz](https://github.com/dvyukov/go-fuzz/) we have proper [fuzztests](https://github.com/gogo/fuzztests).

+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.
+
+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.

+The description (experimental) plugin generates a Description method for each message.
+The Description method returns a populated google_protobuf.FileDescriptorSet struct.
+This contains the description of the files used to generate this message.
+
+It is enabled by the following extensions:
+
+  - description
+  - description_all
+
+The description plugin also generates a test given it is enabled using one of the following extensions:
+
+  - testgen
+  - testgen_all
+
+Let us look at:

+	repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false];
