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