Josh Clark just sent me an e-mail to say:
I’ve just made available a free Perl Critic plugin for the BBEdit text editor for OSX. It gives a handy GUI for running scripts through Perl Critic, and I thought that Mac users of Perl.com might find it useful.
Perl::Critic is one of my favorite open source projects. Integrating this with any editor is fantastic. BBEdit-using Perl hackers, install this plugin now!
