def watchmaker_client(watchmaker_arguments):
    """Return  watchmaker client with defaults."""
    return watchmaker.Client(watchmaker_arguments)

def main(extra_arguments=None, **kwargs):
    """Entry point for Watchmaker cli."""
    prepare_logging(kwargs['log_dir'], kwargs['log_level'])

    sys.excepthook = exception_hook

    watchmaker_arguments = watchmaker.Arguments(**dict(
        extra_arguments=extra_arguments,
