+	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-gogo
+	That word 'gogo' 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 --gogo_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/go_package/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:

+	// whitespace, the same whitespace will be added to every line of the
+	// inserted text.  This is useful for languages like Python, where
