He, he. For the above script to run in sage-ultralight, sage-ultralight must have the same name as sage. Then you get into copyright/trademark related issues (the name "sage" is already taken). Just the same I could create a GUI toolkit named "Qt" that was also released under the SACL license, but you can guess what would happen. Maybe someday a court will clarify what exactly the GPL means...I just hope they don't find that the air we breath is a derived work of some GPL licensed entity. Then, if we breath such air, we would all have to be GPLd :-) Cheers, Brian --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
