Can GPLv3 packages be synced?

Mats Lidell writes: As long as all code is either "legacy" GPLv2-or-later code, or under your authorship, you can dual-license.[1] This would be helpful to us while we figure out what to do about GPLv3 and the main part of XEmacs. In particular we need to make sure that there are no more Bob Weiner surprises (GPLv2-only) waiting for us. Thanks to Michael Albinus, we have an opinion from the FSF Copyright clerk. Basically, it's complex but under some circumstances we can distribute packages under GPLv3 without relicensing either other packages or the core XEmacs. The main consideration, I think, is political: what Richard Stallman will think. I doubt he'll like it very much. I don't really think we have much choice, but we do need to check that everything can be promoted to GPLv3, and do something about anything that can't be promoted. Footnotes: [1] If you've assigned to the FSF, you may need to notify them, but all assignments I've seen require the FSF to either license as you request, or give you permission to "use as you see fit." _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta
