use_json = 'as-json' in args
    throw = 'throw' in args
    percent_autoformat = '%-autoformat' in args

    if 'enable' in args:

    _log()

    if percent_autoformat:
        logger.info('The %s is %d.', 'answer', 47)

    if throw:
        raise Exception('An exception occurred before ending the logging')

    log_helper.end_logging()

text = ''

        return_code = 0
    except Exception as exc:
        logger.exception(str(exc))
