+// protoc-gen-go is 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:
+// 	https://developers.google.com/protocol-buffers/
