Hi guys, I am writing a library for polynomial arithmetic which I might eventually like to see included in Sage. (It is not presently part of FLINT, but maybe one day it will be.)
I would like to release it simultaneously under GPL v2 and GPL v3. I specifically do not want to use the clause "either version 2 of the License, or (at your option) any later version." Basically I don't trust the FSF enough at the moment to release my code under GPL v7, so I want to stick with the existing licenses. Small portions of the source code of the library are adapted from existing software (NTL and FLINT), both of which are released under "version 2, or at your option any later version". It also includes some code from GMP 4.2.1, which is released under "LGPL v2.1, or at your option any later version". Two questions: Q1) Is it legal for me to do this? Am I violating the licenses of NTL, FLINT, or GMP? For example, since NTL is released under "version 2, or at your option any later version", am I violating Shoup's copyright by re-releasing part of his code under only v2 and v3? Q2) If I release under GPL v2 and v3 only, is it possible for Sage to use my code? thanks guys david --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com 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/ -~----------~----~----~----~------~----~------~--~---
