CPAN

CPAN is the magic bullet that all other languages envy.

It's a vast repository of modules that people have contributed.

It stands for Comprehensive Perl Archive Network.

Search for modules at search.cpan.org

http://search.cpan.org is the standard front-end to search the CPAN.It also includes links to most of the rest of these sites.

There's a different interface to CPAN at https://metacpan.org.metacpan.org has more features and links for exploring the CPAN and distributions.

http://cpanratings.perl.org lets you rate and comment on modules and see what others thought of them,before you try.

Submit your bug to RT at http://rt.cpan.org.

http://annocpan.org lets you annotate the documentation for a module,with the hope that the author will incorporate the changes in the future.

http://backpan.perl.org/ has every module ever on CPAN,even if it's old and out of date.
