Google protobuf support for Lua

This project offers a C module for Lua (5.1, 5.2, 5.3, 5.4, and LuaJIT) manipulating Google's protobuf protocol, both for version 2 and 3 syntax and semantics. It splits into the lower-level and the high-level parts for different goals. For converting between binary protobuf data with Lua tables, using pb.load() loads the compiled protobuf schema content (*.pb file) generated by Google protobuf's compiler named protoc and call pb.encode()/pb.decode(). If you don't want to depend Google's protobuf compiler, protoc.lua is a pure Lua module translating text-based protobuf schema content into the *.pb binary format.
