The Perl 5 module 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 Policy modules
are based on Damian Conway's book Perl Best Practices. However,
Perl::Critic is not limited to PBP and will even support Policies
that contradict Conway. You can enable, disable, and customize
those Polices through the Perl::Critic interface. You can also
create new Policy modules that suit your own tastes.
A front-end script, perlcritic, is provided.
