+Usage: list_login_items_for_app <path.app>
+
+Given an Application (app) bundle directory on disk, find all
+login items associated with that app, which you can use in a
+Cask uninstall stanza, eg
+
+    uninstall :login_item => 'login item name'
+
+Note that you will likely need to have opened the app at least
+once for any login items to be present.
+
+See CONTRIBUTING.md for more information.
