+Copyright 2010 The Go Authors.
+https://github.com/golang/protobuf
+
+This package and the code it generates requires at least Go 1.4.
+
+This software implements Go bindings for protocol buffers.  For
+information about protocol buffers themselves, see
+	https://developers.google.com/protocol-buffers/
+
+## Installation ##
+
+To use this software, you must:
+- Install the standard C++ implementation of protocol buffers from
+	https://developers.google.com/protocol-buffers/
+- Of course, install the Go compiler and tools from
+	https://golang.org/
+  See
+	https://golang.org/doc/install
+  for details or, if you are using gccgo, follow the instructions at
+	https://golang.org/doc/install/gccgo
+- Grab the code from the repository and install the proto package.
+  The simplest way is to run `go get -u github.com/golang/protobuf/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.
+
+
+## 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 --go_out
+parameter set to the directory you want to output the Go code to.
+
+	protoc --go_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.
+
+==========
+
+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.
+  - Enum types do not get an Enum method.
+
+Consider file test.proto, containing
+
+```proto
+	syntax = "proto2";
+	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/golang/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 --go_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 --go_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.
+
+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.

+// Options
+
+// Each of the definitions above may have "options" attached.  These are
+// just annotations which may cause code to be generated slightly differently
+// or may contain hints for code that manipulates protocol messages.
+//
+// Clients may define custom options as extensions of the *Options messages.
+// These extensions may not yet be known at parsing time, so the parser cannot
+// store the values in them.  Instead it stores them in a field in the *Options
+// message called uninterpreted_option. This field must have the same name
+// across all *Options messages. We then use this field to populate the
+// extensions when we build a descriptor, at which point all protos have been
+// parsed and so all extensions are known.
+//
+// Extension numbers for custom options may be chosen as follows:
+// * For options which will only be used within a single application or
+//   organization, or for experimental options, use field numbers 50000
+//   through 99999.  It is up to you to ensure that you do not use the
+//   same number for multiple options.
+// * For options which will be published and used publicly by multiple
+//   independent entities, e-mail protobuf-global-extension-registry@google.com
+//   to reserve extension numbers. Simply provide your project name (e.g.
+//   Objective-C plugin) and your project website (if available) -- there's no
+//   need to explain how you intend to use them. Usually you only need one
+//   extension number. You can declare multiple options with only one extension
+//   number by putting them in a sub-message. See the Custom Options section of
+//   the docs for examples:
+//   https://developers.google.com/protocol-buffers/docs/proto#options
+//   If this turns out to be popular, a web service will be set up
+//   to automatically assign option numbers.

+	A plugin for the Google protocol buffer compiler to generate Go code.
+	Run it by building this program and putting it in your path with the name
+		protoc-gen-go
+	That word 'go' at the end becomes part of the option string set for the
+	protocol compiler, so once the protocol compiler (protoc) is installed
+	you can run
+		protoc --go_out=output_directory input_directory/file.proto
+	to generate Go bindings for the protocol defined by file.proto.
+	With that input, the output will be written to
+		output_directory/file.pb.go
+
+	The generated code is documented in the package comment for
+	the library.
+
+	See the README and documentation for protocol buffers to learn more:

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

+//     any.Pack(foo)
+//     ...

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

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