def usage
  <<~EOS
    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.
