Writing a plug-in for the GIMP does not do anything prohibited by copyright. Even if you include header files and such, that comes under "there's just one way to do it", which makes it OK. So you don't need permission and you don't need to distribute it under any particular license. If the program depends on the other program in some manner, then yes you do. Some GPL theorists would like it if making a program that inter-operates at the code level with another program would entangle its source in the copyrights of that program, but in fact that does not happen. Ofcourse it does happen. _______________________________________________ gnu-misc-discuss mailing list gnu-misc-discuss@gnu.org http://lists.gnu.org/mailman/listinfo/gnu-misc-discuss
