Really great CPAN dist. If you've installed several Perls via perlbrew and you want to automate your testing across all those Perls, this dzil plugin does the job. The documentation could be more thorough. I'd like to see a troubleshooting section with suggestions on how to handle common problems so you don't have to hand edit the generated LocalBrew tests and comment out "close STDERR" just to find out why a given brew test is failing. Perhaps the interface could "save up" any error messages and spit them out when done, like Test::NoWarnings?
5 stars for usefulness and enhanced testing efficiency!
