Right, but the module license is set to GPL which means GNU Public License v2 or
later, see [1]. So, there is a mismatch. In such cases I assumed GPL-2.0+ as the
default. These mismatches are common so I think that should be fine for the
authors, if someone is disagree just let me know and I will change.

 Enric
