// 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.
