the previous configuration.
    :param kw: Refer to :func:`connect_to_syslog()`.
    :returns: A :class:`~logging.handlers.SysLogHandler` object or
              :data:`None`. If an existing handler is found and `reconfigure`
              is :data:`False` the existing handler object is returned. If the
              connection to the system logging daemon fails :data:`None` is
              returned.

    .. note:: When the logger's effective level is too restrictive it is
              relaxed (refer to `notes about log levels`_ for details).
