And Renaud Rioboo writes in http://lists.gnu.org/archive/html/axiom-developer/2005-10/msg00125.html ========================== Recently Martin Rubey thought it could be a good idea to release them and I have of course no objection on that point nor on sharing these sources with the community. If there is some interest on it you may include it into the Axiom distribution with the same permissions than the rest of the software. While I wait for my lab to give me the necessary permissions to be able to use Axiom and export this software you may find it's sources at the unlisted url http://rioboo.free.fr/CadPub/ ========================== That sounds as if that is licensing the source code under BSD. I don't exactly understand what is meant by "permission to be able to use Axiom and export this software". Maybe he meant the commercial version of Axiom. > Including it in FriCAS would effectively change FriCAS licence to > GPL. In fact, I'd love FriCAS under GPL. But no, if FriCAS includes a SPAD source package under GPL that doesn't change the license of FriCAS to GPL. It changes the license of a *binary* distribution to GPL, so that such a binary distribution must be accompanied with sources and the whole thing must be GPL. You would then still be allowed to distribute the FriCAS sources under BSD with one (or several) source files under GPL. Since there is no linking in the source-only distribution, nothing in the GPL 3.0 license text says that a mere packaging of BSD and GPL files would automatically make the BSD files be licensed under GPL. IANAL, but I'm pretty sure that the FSF argues in the same way.
