"""Parses the Maven pom.xml file for which files to include in a lite build.
Usage:
protobuf_lite_java_parse_pom.py {path to pom.xml}
This is a helper file for the protobuf_lite_java target in protobuf.gyp.
It parses the pom.xml file, and looks for all the includes specified in the
'lite' profile. It does not return and test includes.
The result is printed as one line per entry.
