    mosquitto has been installed with a default configuration file.
        You can make changes to the configuration by editing
        #{etc}/mosquitto/mosquitto.conf

    If this is your first install, automatically load on login with:
        mkdir -p ~/Library/LaunchAgents
        cp #{plist_path} ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

    If this is an upgrade and you already have the #{plist_path.basename} loaded:
        launchctl unload -w ~/Library/LaunchAgents/#{plist_path.basename}
        cp #{plist_path} ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

    Start the broker manually by running:
        mosquitto -c #{etc}/mosquitto/mosquitto.conf

    Python client bindings can be installed from the Python Package Index
        pip install mosquitto

    Javascript client is available at
        http://mosquitto.org/js/
