Unchained, Ultimate, Ultra, Up Yours, Underworld, Underground, Unified, Unity, etc. You know the drill. This takes care of the "standalone" problem with the wrong name, and the recent snafu with multiple developers working on the same files simultaneously...expect me (and probably others) to start locking dirs when updates are taking place. And yes, this update is really as large as it looks. Software only at the moment, but I will have the makefile updated to build the GL builds as well.
