There is also a good section in Programming Perl 3rd Edition on it. It tells you all you need to know about installing, writing, and storing your modules (on CPAN)and I think Damian Conway has a book on it too. Other than that, a nice search around this site and on http://google.com always provide more than enough information for me, so best of luck to ya!
