/**
@defgroup protobuf3 Protocol Buffers [incomplete]
 
@brief Exchange data with protobuf classes.
 
Only trivial protobuf messages are supported: no repeated fields, no nested
messages, etc. The main limitation is that protobuf C++ API depends on both the
name and the type of message fields, which makes it impossible to handle either
via templates or preprocessor macro.
