The key is in the docs you posted, specifically, "will provide a help message using module Pod::Usage", I would suggest you have a look at the docs for that module it should clear things up nicely. Particularly have a look at the section "Recommended Use" that should help even more. I have had good luck combining the two, though was unaware that this could be handled automagically for me, very cool, I usually just code it in to catch --help and -h and call pod2usage explicitly, god Perl+CPAN rocks... I posted a template that takes advantage of this strategy late last year if you want to check the archives, or e-mail me off list and I will fire you a copy.... http://danconia.org -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
