Hi Warrick,

Thanks for wanting to share your code and for thinking about the best way
to do it.  mesa-users doesn't have many lawyers among the subscribers (that
I know of!) so you may not get a conclusive answer.

MESA is under LGPL v2.1 and there are some GNU-centric thoughts about
various open-source licenses here:


Good luck!
