The Artistic License is more permissive than the GPL. As most people read the GPL, if you copy-n-paste even __one__ __line__ of code from GPL source to any other file, that other file automatically becomes subjec to the GPL. As per my reading of paragraph #7 of the Artistic License, the only requirements for code-reuse are (a) your "reuse" does not constitute wholesale copying of the entire source with a 2-line tweak, but are only reusing chunks; and (b) you clearly label where you got the copied chunks from. The upshot is: you cannot put a GPL'd file into a codebase under the Artistic License without changing the license of the entire codebase to GPL. You can, however, put an Artistic License into a GPL'd codebase with no effect on the other files in the codebase (which remains under the GPL). -- John Weiss
