testing/urbanterror-data is not redistributable
From their FAQ:
Urban Terror is a mod for Quake 3 Arena. Urban Terror can be freely distributed over the internet, unmodified, without charging for the product. Urban Terror uses the Quake 3 SDK license. This means the game code (the .qvm's in zpak000.pk3) are closed source and can only be distributed electronically over the internet, not on cd or dvd. The non-code data files of Urban Terror (zpak000-assets.pk3) can go on any medium however. The full license texts come with the installer, they outweigh the information provided here.
So, I checked the license itself:
$ abuild clean unpack
$ cd src/UrbanTerror43/q3ut4
$ strings QIIIA_Game_Source_License.doc

Needless to say that does not meet the guidelines for inclusion in the Alpine distribution.
