I cannot see how code written in elisp itself would need to be GPL. Distributing it *with* emacs would probably require it being GPLed but the source code itself, if not based on already GPLed code, should be fine, e.g. in the context of a tutorial. Anyway, I think we've beaten this to death already. Time to get real work done! :-) -- : Eric S Fraga (0xFFFCF67D), Emacs 25.0.50.1, Org release_8.3beta-1293-g985420
