title: What do the icons in Eclipse mean?
body: <ul>
  <li>What do the icons in the Eclipse debugger mean?</li>
  <li>What do the icon decorators in Eclipse mean?</li>
  <li>What do the icons in Eclipse's Package Explorer mean?</li>
  <li>What do the little letters on top of Eclipse icons mean?</li>
  <li>What's the difference between the two error icons in Eclipse (the x in the red circle and the one with the light bulb)?</li>
  </ul>
  
  <p>I just came to SO looking for this, didn't find it, and found it on my own elsewhere. But I thought it would be good for SO to have the answer for future reference; I wondered about them all the time when I was new to Eclipse (this was before I discovered SO).</p>
