I've forked the protpy package into propy3 in order to make it usable for Python 3 users. I'm not a user of that package myself and have no clue of protein computations. However, in order to make it useful and ensure it works, I ended up spending way more time on it than I originally thought.
Now people want me to add a license file. Several attempts to reach the original authors were unsuccessful, so I cannot simply align with them what they want.
The original website mentions
GNU GPL v2, so I will put the forked project under
GNU GPL v2 as well.
I feel like the original authors are still the authors of this package, as most of my changes are not affecting what the package does, but how it's structured / how it works / adding tests / dealing with community support. However, I do want to change some interfaces.
Now I wonder: Is it even ok to leave them in the "author" field? Should I add myself to them? Should I remove them from the author field and mention in the README that this was forked from them?
