title: How can I rename multiple files in Eclipse?
body: <p>I'd like to rename multiple files(/resources) in Eclipse.</p>
  
  <p>Functionality by order of usefulness:</p>
  
  <ol>
  <li>Rename files in search results (i.e. search for pattern, see which files match</li>
  <li>Rename files using a regexp which runs on all filenames (e.g. <code>s/stuff(.*)\.c/stuff\1.c.old/</code>)</li>
  <li>Rename files in the selection in the package explorer (F2 doesn't do this...)</li>
  </ol>
  
  <p>How can I do this? Is there a relevant add-on maybe?</p>
