devel/rubygem-cucumber-messages15/pkg-descr

-Cucumber Messages is a message protocol based on Protocol Buffers. It allows one
-process to construct message objects and send them to another process. Protobuf
-takes care of serialising those messages to a binary format, and deserialise
-them on the other end.
