// Html support for Protocol Buffers - Google's data interchange format
//
// protoc-gen-htmltemplate is a plugin for the Google protocol buffer compiler to generate
// html template files. Run it by building this program and putting it in your path with
// the name
// 	protoc-gen-htmltemplate
// That word 'htmltemplate' 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 --htmltemplate_out=output_directory input_directory/file.proto
// to generate bindings for the protocol defined by file.proto.
// With that input, the output will be written to
// 	output_directory/file.pb.moustache.html
//
// 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/
