      # Provides helpers similar to AbstractController::Translation
      # but by default uses `action_name_i18n_key` in lazy translation keys
      # which strips `!` from action names by default. This makes translating
      # strings for commands more convenient.

      # To disable this behaviour use `alias_method :action_name_i18n_key, :action_name`.
