M4RI GPL → LGPL (?)

[Martin Albrecht]

Hi all,

over at [m4ri-devel]

https://groups.google.com/forum/#!topic/m4ri-devel/dJ4fCyiZRY8

we are discussing - well, currently stating our positions - on whether M4RI
should be re-licensed to LGPL from GPL. This is because Mate Soos asked us to
consider this because it would allow him to release some piece of code under
the MIT license (in a meaningful way).

I know this troll bait, but if any of you can think of ways in which such a
move would negatively affect Sage let us know.

In any case, I should mention that it's not that likely that the switch will
happen (as far as I can see): some developers are opposed to it and we haven't
tracked down/gotten replies from all people.

Cheers,
Martin
