You could but that is not what I said I said that the same copyright protection which applies to a program does not apply to its output. You could use winzip pro (which I assume for the same of discussion is closed source but creates tarballs) to create sage-2.10.3.tar and the tarball would still be GPL'd. That is because the copyright protection which applies to winzip pro does not apply to its output. > > 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 -~----------~----~----~----~------~----~------~--~---
