"""Generate java source files from protobufs
Usage:
protoc_java.py {protoc} {proto_path} {java_out} {stamp_file} {proto_files}
This is a helper file for the genproto_java action in protoc_java.gypi.
It performs the following steps:
1. Deletes all old sources (ensures deleted classes are not part of new jars).
2. Creates source directory.
3. Generates Java files using protoc.
4. Creates a new stamp file.
