I pushed package freedoom to the extras-devel. It is Doom2-datapack for prboom. [http://www.nongnu.org/freedoom/ version 0.7]

It uses and depends prboom, so if you haven't prboom installed already, it is automatically installed.

prboom and freedoom both have own icons for menu.
Freedoom-entry always starts freedoom, prboom-entry can start another iwad's (e.g. if you have earlier installed prboom, you have doom-wad-shareware and it is started).
