- comment (str): A comment delimiter.  This should only be changed when parsing non-Cisco IOS configurations, which do not use a !  as the comment delimiter.  ``comment`` defaults to '!'
            - debug (bool): ``debug`` defaults to False, and should be kept that way unless you're working on a very tricky config parsing problem.  Debug output is not particularly friendly
            - ignore_blank_lines (bool): ``ignore_blank_lines`` defaults to True; when this is set True, ciscoconfparse ignores blank configuration lines.  You might want to set ``ignore_blank_lines`` to False if you intentionally use blank lines in your configuration (ref: Github Issue #2).

        Returns:
           - An instance of an :class:`~ciscoconfparse.IOSConfigList` object.
