title: node.js external libraries in webstorm
body: <p>I noticed that webstorm has an external libraries node in the project explorer.  In that I see Node.js 0.6.15 and also an option for Node.js Globals.</p>
  
  <p>Two questions:</p>
  
  <ol>
  <li>Can I have it reference node 0.8?</li>
  <li>What is Node.js Globals for?</li>
  </ol>
  
  <p>Are the external libraries used for code completion?</p>
