Emacs Flymake Perl::Critic

Emacs Flymake Perl::Critic is a plugin for Emacs that hooks Emacs Flymake up to the Perl::Critic static analysis tool for Perl, providing you with on-the-fly feedback on code syntax, style and other warnings.

If you're familiar with the lint tools for various languages, this is what Perl::Critic provides.
