- Open Automator
- Start a new "Application" project
- Drag the "Run Shell Script" action into the right workflow panel, set the "pass input" drop-down to "as arguments" and edit the script to (see screenshot below):
/opt/local/bin/python /Users/michaelmarth/Development/Code/mp3tagger/tag_groupings.py -d "$f"
(you will have to adapt the paths to your local setup)
- Save the application and happily start dropping mp3 folders onto the application's icon.
