+
+          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.
