    # To configure this gem in your application, simply add the following code in your application and set the
    # appropriate configuration settings.
    #
    # @example
    #
    #    SimpleCommand::Dispatcher.configure do |config|
    #       config.allow_custom_commands = true
    #    end

    class Configuration

      # setting is set to *true*, any command class will be considered acceptable to run, regardless of
      # whether or not the class prepends the *SimpleCommand* module.
