Manage Unreal Tournament cache files

This is a little Python script to manage cache files for Unreal Tournament, been using it for years, figured I’d put it here. I only used/tested this with the original UT on Windows and FreeBSD, should work for Linux and MacOS X.

This script will only rename the files to the correct name in the Cache/ directory, it doesn’t put them in the correct UT Directory (System/, Textures/, etc.). This is a feature and not a bug because when you’re using mods you often don’t want to use the standard UT directories, there’s no way to figuring out which files belongs to which mod (or even if it belongs to any mod).

A few simple commands can move the files:

$ utdir=/usr/local/share/linux-ut
$ mv *.u "$utdir/System/"
$ mv *.utx "$utdir/Textures/"

etc…
