Comment 4 for bug 337851

Its a complex C++ library, this is why its so big. It speeds up the parsing of all the XML data in /usr/share/compiz by building a protobuf based cache of them. This gives me a improvement from 3s to 2.1s startup time for compiz on my system. I don't have a mini9 so I was not able to test it on the reference system.

Its tested by the users of the compiz PPA, me and Seb. Its also default in the upcomming 0.8 release of compiz.
