    <para>
      <application>NetworkManager</application> is a set of co-operative
      tools that make networking simple and straightforward. Whether WiFi,
      wired, 3G, or Bluetooth, NetworkManager allows you to quickly move from
      one network to another: Once a network has been configured and joined
      once, it can be detected and re-joined automatically the next time it's
      available.
