I still don't understand how so.

That's why I say a best-practice solution should be established. In this case, if the actual main function is invoked through -c, the -c script could get a sys.path.append statement as well. > The -z argument makes it extremely simple: the user decides which python > to run, and the program is run directly just like it would if it was > unpacked and run that way. Really? I think there a still a number of subtleties, like what sys.argv[0] will be, and how sys.path will look like. It's definitely *not* the same as if you unzipped it, and ran the unzipped one. > I disagree with both statements.
