Hello Sage team,
great work so far, keep pushing forward! I've got the following question: Does a new SPKG, whose contents are licensed under GPLv3+ ("three plus"), fulfil your license requirement in order to become part of the Sage core? In your Wiki (http://www.sagemath.org:9001/spkg/InclusionProcedure? highlight=%28SPKG%29) you say "GPL version 2+ compatible license.", regarding e.g. JSAGE you say (http://www.sagemath.org/jsage/guidelines.html): "License: All software that is published in JSAGE must be licensed under a "GPL v2 or later"-compatible license.". By "GPLv3+" I mean licensed using the usual catchphrase: "The xyzprog is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 3 of the License, or (at your option) any later version.", referring to the "GNU GENERAL PUBLIC LICENSE Version 3, 29 June 2007". (And analogously "GPLv2+", referring to GPL "Version 2, June 1991"; LGPL is the "Lesser" version of a GPL licence.) GPLv3+ is more restrictive than GPLv2+, both in theory and in practice, so my question above is not so innocent as it might seem at first. Parts of the current SAGE v3.0.2 are licensed (L)GPLv3+, and there is the SAGE motto: "Building the car instead of reinventing the wheel". This would lead to a strong assumption that the answer to my question above is "Yes" anyway. However, the fine distinction between (L)GPLv2+ and (L)GPLv3+ was one of the keypoints in the recent (ongoing?) generation-conflict flamewar on the mailing-list "gmp-discuss", an outtake from the middle of which was posted in the Sage Project Blog (see "http://planet.sagemath.org/", entry from May 29th). I do not want to discuss this here, I just want clarity about the Sage team's policy regarding the future inclusion of GPLv3+'ed code into the mainline Sage core. (Say explicitly extending ".../sage/modular/modsym/"). If there's a quick answer, good. (I might have been missing something, please just tell me, thanks!) If your answer takes some time, that's OK for me, too.
