[Python-Dev] Would GPL on python-mode.el be a problem?

Not too long ago, Matthias Klose submitted an enormous patch (1370 lines) to python-mode.el (only 3804 lines itself): https://sourceforge.net/tracker/index.php?func=detail&aid=875596&group_id=86916&atid=581351 I decided to start disecting it today and immediately ran into this comment by Dave Love (fx@gnu.org): ;; This file contains significant bits of GPL'd code, so it must be ;; under the GPL. -- fx During the python-mode project's short life, I've copied python-mode.el over to the Python project's Misc directory a few times. I thought I'd better ask if GPL-ness would present a problem. I have always remained blissfully unaware of licensing details, so I have no grasp of what the ramifications are. Thx, Skip
