Ruby extension that implements Protocol Buffers functionality in Ruby

The Ruby extension makes use of generated Ruby code that defines message and
enum types in a Ruby DSL.  You may write definitions in this DSL directly,
but we recommend using protoc's Ruby generation support with .proto files.
The build process in this directory only installs the extension; you need to
install protoc as well to have Ruby code generation functionality.  You can
build protoc from source using bazel build //:protoc.
