How to use the dotbot.messenger.Messenger function in dotbot

def main():
    log = Messenger()
    try:
        parser = ArgumentParser()
        add_options(parser)
        options = parser.parse_args()
        if options.version:
            print('Dotbot version %s (yaml: %s)' % (dotbot.__version__, yaml.__version__))
            exit(0)
        if options.super_quiet:
            log.set_level(Level.WARNING)
        if options.quiet:
            log.set_level(Level.INFO)
        if options.verbose:
            log.set_level(Level.DEBUG)
        if options.no_color:
            log.use_color(False)
        plugin_directories = list(options.plugin_dirs)

def __init__(self, base_directory):
        self._log = Messenger()
        self._setup_context(base_directory)
        self._load_plugins()

def __init__(self, context):
        self._context = context
        self._log = Messenger()
