title: Delphi - Reverse Lookup ' who includes this unit'
body: <p>I am debugging a large application distributed over many units.
  I ran into a compilation error in a low level unit and do not have the slightest idea in which part of the application this unit is referenced. Is there a way to use RAD studio 2010's IDE to create some kind of include-graph? </p>
  
  <p>As most of the units used are not part of the project  and spread over quite a branchy source tree, i can not simply use the 'find in files' option.</p>
  
  <p>I am currently traversing through my tree using a search-in-files-utility, but this is cumbersome.</p>
  
  <p>Do you know of  amore elegant way? 
  Development is in Embercadero RAD studio 2010, windows XP 32.</p>
