[bug#56274] [PATCH 0/1] Add python-gp-extras

[Wiktor Żelazny]

This project is not active, anymore, but appears to be still compatible
with scikit-learn. I’m concerned about the license. There are “License:
BSD 3 clause” comments at the top of the scripts, but that’s all. I’m
unsure whether such a form of licensing is sufficient.
