--- Comment #11 from Diogo Melo dmelo87@gmail.com --- Hi.
About the license, it was my mistake. The intended license was GPLv3.
Regarding building it for python2 and/or python3, I've seen that from fc22 forward, for python executables, it is advisable to build it for python3 and, if possible, python2 too. I've decided to build it only for python3. I've replaced '#!/usr/bin/env python2' with '#!/usr/bin/python3'.
The spec file is now on GitHub https://github.com/dmelo/vswm/blob/master/distros/fedora/vswm.spec
Here is the Copr URL for the new version https://copr.fedorainfracloud.org/coprs/dmelo/VSWM/build/454419/
I will now work on error handling, as you suggested.
