Geogebra code is licensed GPL according to their page. But they also claim that Geogebra is free "for noncommercial use only". These two statements are mutually incompatible as I mentioned before. > Whether or not the dual licensing of GeoGebra makes it a practical > proposition to use the source code in Sage, and do a re-write of the > installers and documentation is another matter. > > If (and I can't be bothered to check) autoconf and automake are used [...] Thanks for sharing your thoughts, though I wish you could "be bothered to check", since then your comments would be even more valuable. -- William --~--~---------~--~----~------------~-------~--~----~ 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://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
