Go support for protocol buffers.
Consists of a compiler plugin and the support library, all written in Go.
This is a complete implementation except for:
- Extensions in the plugin
- coming soon
- support is already in the library
- Services (RPC)
- needs an external definition to honor before supporting.
- Insertion points in the plugin
- may come
