def log_level(self, value):
        """
        Sets the verbosity of ``pwntools`` logging mechanism.

        More specifically it controls the filtering of messages that happens
        inside the handler for logging to the screen. So if you want e.g. log
        all messages to a file, then this attribute makes no difference to you.

        Valid values are specified by the standard Python ``logging`` module.

        Default value is set to ``INFO``.

        Examples:

            >>> context.log_level = 'error'
            >>> context.log_level == logging.ERROR
            True
            >>> context.log_level = 10
            >>> context.log_level = 'foobar' #doctest: +ELLIPSIS
