Good news: LiE is now GPL'd. This does a number of Lie algebra computations and representation-theoretic computations which people on this list have expressed interest in.

As is now indicated on the Lie home page http://www-math.univ-poitiers.fr/~maavl/LiE/ you can distribute LiE under the (GNU) LGPL. It is not clear to me why this choice was made, since LiE is not distributed as a library, but I think this is because a part of LiE has thus been incorporated into Magma. In any case, if you read the fine print of the LGPL, it is allowed to take a copy and distribute that copy under the GPL (but that copy can then no longer be converted back to LGPL). I hope this helps you out, best regards, -- Marc van Leeuwen --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
