The software is Rolisteam
I haven't found any software for tabletop roleplaying on Solus, that's why I think a software like Rolisteam can be useful and more reliable than online web based comparable projects like roll20.net which has regular issues. Solus is know for it's gaming capabilities, so why not have a tabletop gaming software ?
It also is not dependant on an online service.
Rolisteam is under the GPLv2 licence
Tarballs : http://sourceforge.net/projects/rolisteam/files/1.8.2/rolisteam-1.8.2.tar.gz/download http://sourceforge.net/projects/rolisteam/files/1.8.2/rcse-1.0.3.tar.gz/download there are these 2 files proposed to download, I'm not an expert is package making so I linked both)
Have a good day and sorry for any error in the request form.
