Hi Andreas, I added a master-contrib branch which contains a bart-cuda package which is identical to bart except it activates cuda support in the bart binary.
I am not sure about the control file. I added Provides: bart Conflicts: bart Replaces: bart but I am not so sure whether this is correct. Best.
