Perl::Critic is an extensible framework for creating and applying coding standards to Perl source code. Essentially, it is a static source code analysis engine. Perl::Critic is distributed with a number of Perl::Critic::Policy modules that attempt to enforce various coding guidelines. Most Policies are based on Damian Conway's book Perl Best Practices. You can choose and customize those Polices through the Perl::Critic interface. You can also create new Policy modules that suit your own tastes. For a convenient command-line interface to Perl::Critic, see the documentation for perlcritic. If you want to integrate Perl::Critic with your build process, Test::Perl::Critic provides a nice interface that is suitable for test scripts. WWW: http://search.cpan.org/dist/Perl-Critic/
