Description: "Protobuf: The Google protobuf compiler and runtimes for various languages"

Local Modifications: Initial changes include support for the javamicro
runtime, see java/README.txt for more details.

Protocol Buffers are a way of encoding structured data in an efficient
yet extensible format. Google uses Protocol Buffers for almost all
of its internal RPC protocols and file formats.

Initially the protoc compiler is not integrated into the Android build system
and the Android.mk will simply build the javamicro runtime static library.
