I don't know what the hell kind of crazy operating systems you people are using, but have you ever seen any that allowed parentheses in a filename?

If you have any trouble sounding condescending, find a Unix user to show you how it's done.

Does that answer your question? ;)

Oh, and under MacOS, it's even easier to use filenames with parentheses in them, because you don't have to worry about escaping them.
