title: How to force emacs projectile to reinitialize a project?
body: <p>I'm using projectile with emacs to manage a large project.</p>
  
  <p>I moved a number of directories with scores of files.</p>
  
  <p>The old file paths are still showing up in projectile find file (C-c p f).</p>
  
  <p>How do I remove them in bulk or force projectile to re-initialize the project?</p>
  
  <p>I've tried:</p>
  
  <ul>
  <li>projectile-purge-dir-from-cache</li>
  <li>projectile-invalidate-cache</li>
  <li>quitting emacs, deleting ~/.emacs.d/projectile.cache, restarting emacs</li>
  <li>adding a .projectile file with 'exclude' options for the original dirs</li>
  </ul>
  
  <p>After all of these, the same original list of old paths/files still appears on C-c p f.</p>
