-/**
- * Strip away all unneeded classes from protobuf-java-*.jar to make a LITE version of the protobuf runtime.
- * To do this, we load pom.xml from protobuf jar and heuristically extract information about which classes
- * are kept in the lite runtime.
- * (This could be done with actually parsing the XML, but this solution works just fine at the moment.)
- * Then we take the full protobuf.jar and copy its contents to another jar, except those classes
- * which are not needed in the lite runtime.
