title: How to Create class diagram from Code?
body: <p>I have project under version control. I need to study code that is not mine. I am trying to find a better way than writing down the classes and their relationships in UML.  </p>
  
  <p>Is there a tool that does this automatically? </p>
  
  <p><strong>Note:</strong> The files are read-only so I can not use a tool that would have to modify them. I am working in Eclipse environment.</p>
