I don't know if I'd call myself a core developer or not but GeoGebra does not seem to be entirely GPL'd. It appears that the documentation isn't GPL'd nor is the "installer" and the language files. Language files I guess count as data, so maybe those are okay to distribute in a GPL'd program, but that is a guess. Is it possible to create a functional optional geogebra package which strips out the non-GPL'd stuff? > > Ted > > > > --~--~---------~--~----~------------~-------~--~----~ 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 -~----------~----~----~----~------~----~------~--~---
