Description

Hello there,

Thank you for the great work you're doing building ScanPy!

I am currently learning about open-source licenses and the intricacies of copyright. Especially regarding management of GPL dependencies and when the viral copyleft clause is triggerred or not.
It looks like the ScanPy team explored this question already as the projet is licensed under BSD while it is leveraging GPLed dependencies like leidenalg, python-igraph or louvain.

Understanding how you handled this question would greatly help me, could you tell me?
Maybe there are discussions recorded somewhere?

Best,
Fabien
