I haven't looked through your code, but I just wanted to comment on your, er, comment about being "NON CPAN-module-using". You might note that File::Find is a core module (you can find the list of these in your perlmodlib perldoc). CPAN is not required to get it -- it is almost certainly included with your copy of perl itself. This is usually the thing to use, unless there is something very specific that this code does that File::Find does not. (Again, there might be, as I haven't looked at your code. But I'd be shocked if it couldn't be done with File::Find.)

Please don't take this as a personal attack against you or your code. I noticed File::Find mentioned as a "CPAN module" in another note as well, so I figured the matter might use some clarification.
