--- Comment #3 from Robert-André Mauchin zebob.m@gmail.com --- (In reply to srakitnican from comment #2)
I am confused about that one, I've added this file because it is the only text that describes the actual license used (GPLv2+). COPYING and LICENSE.md contains license text for GPLv3 and LGPLv3 respectively. I am not an expert, but I think there is quiet a difference between the two, and I would say there is at least some difference between GPLv2 and GPLv3.
Nothing indicates that this app is GPLv2+. License: should be GPLv3+ or LGPLv3+ and you should include both COPYING and LICENSE.md in %license.
