title: How to add a preference page?
body: <p>I want to add a preference page in my RCP program, just like you see in the eclipse, when you click Windows->Preferences->General, a preference page appears in the right panel. But I'm not familiar about RCP, how can I add a option in the Windows->Preferences lists, and make it work like the "General" option?</p>
  
  <p>Thanks a lot.</p>
