+# Go support for Protocol Buffers
+
+Google's data interchange format.
+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/{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.
+
+
+## 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.
+  - 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/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.

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

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

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

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

+	A plugin for the Google protocol buffer compiler to generate Go code.

+		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.

+	// as the insertion_point.  Code inserted at this point will be placed
+	// immediately above the line containing the insertion point (thus multiple
+	// insertions to the same point will come out in the order they were added).
+	// The double-@ is intended to make it unlikely that the generated code
+	// could contain things that look like insertion points by accident.
+	//
+	// For example, the C++ code generator places the following line in the
+	// .pb.h files that it generates:
+	//   // @@protoc_insertion_point(namespace_scope)
+	// This line appears within the scope of the file's package namespace, but
+	// outside of any particular class.  Another plugin can then specify the
+	// insertion_point "namespace_scope" to generate additional classes or
+	// other declarations that should be placed in this scope.
+	//
+	// Note that if the line containing the insertion point begins with
+	// whitespace, the same whitespace will be added to every line of the
+	// inserted text.  This is useful for languages like Python, where
+	// indentation matters.  In these languages, the insertion point comment
+	// should be indented the same amount as any inserted code will need to be
+	// in order to work correctly in that context.
+	//

+// `Any` contains an arbitrary serialized protocol buffer message along with a
+// URL that describes the type of the serialized message.
+//
+// Protobuf library provides support to pack/unpack Any values in the form
+// of utility functions or additional generated methods of the Any type.
+//
+// Example 1: Pack and unpack a message in C++.
+//
+//     Foo foo = ...;
+//     Any any;
+//     any.PackFrom(foo);
+//     ...
+//     if (any.UnpackTo(&foo)) {
+//       ...
+//     }
+//
+// Example 2: Pack and unpack a message in Java.
+//
+//     Foo foo = ...;
+//     Any any = Any.pack(foo);
+//     ...
+//     if (any.is(Foo.class)) {
+//       foo = any.unpack(Foo.class);
+//     }
+//
+//  Example 3: Pack and unpack a message in Python.
+//
+//     foo = Foo(...)
+//     any = Any()
+//     any.Pack(foo)
+//     ...
+//     if any.Is(Foo.DESCRIPTOR):
+//       any.Unpack(foo)
+//       ...
+//
+// 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` contains an arbitrary serialized protocol buffer message along with a
+// URL that describes the type of the serialized message.
+//
+// Protobuf library provides support to pack/unpack Any values in the form
+// of utility functions or additional generated methods of the Any type.
+//
+// Example 1: Pack and unpack a message in C++.
+//
+//     Foo foo = ...;
+//     Any any;
+//     any.PackFrom(foo);
+//     ...
+//     if (any.UnpackTo(&foo)) {
+//       ...
+//     }
+//
+// Example 2: Pack and unpack a message in Java.
+//
+//     Foo foo = ...;
+//     Any any = Any.pack(foo);
+//     ...
+//     if (any.is(Foo.class)) {
+//       foo = any.unpack(Foo.class);
+//     }
+//
+//  Example 3: Pack and unpack a message in Python.
+//
+//     foo = Foo(...)
+//     any = Any()
+//     any.Pack(foo)
+//     ...
+//     if any.Is(Foo.DESCRIPTOR):
+//       any.Unpack(foo)
+//       ...
+//
+// 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;
