This is a MetaCPAN LaunchBar action that can search MetaCPAN based on your input. Including autosuggestion completion.
Download the recent release, unzip and double click to have LaunchBar automatically install the action.
If you'd like to use the latest features as they are added to the master
branch you can clone the repository to your LaunchBar Actions folder:
