JaWi is absolutely right. You should NEVER rebuild a wheel (especially a GREAT wheel that's already written in C by the GNU fellas) in perl unless you're on a system where you absolutely CANNOT use them or are writing something that HAS to be VERY portable.

And in case you're wondering, you can even have the GNU utilities on a Win32 system. Check out http://gnuwin32.sourceforge.net/. It includes the join GNU utility. Excellent stuff, use it all the time.
