From a .proto file, autogenpb will:

	* auto generate Sort(), Marshal() and GUI() functions in .pb.go files
	* auto format the .proto file (like goimport does for .go files)
	* encourages (enforces?) plural struct names (like rails)

See the sources for an example .proto files

Example usage:

	autogenpb --proto foo.proto --package main
`
}
