title: Deleting not needed bundles from Symfony 2?
body: <p>Is possible to delete bundles not needed in order to keep the project clean? I'm using Symfony2 with propel to build a RESTful interface. Don't need:</p>
  
  <ul>
  <li><strong>Twig</strong></li>
  <li><strong>Doctrine2</strong> (i prefer Propel instead)</li>
  <li><strong>Assetic</strong> (without Twig assetic does not make sense, correct me if i'm wrong)</li>
  <li><strong>Security</strong> (no need to model roles)</li>
  </ul>
  
  <p>I can't find any how-to in order to remove uneeded bundles. Any help is much appreciated.</p>
  
  <p><strong>EDIT</strong>: monlog is the logger, not mongodb. Need it!</p>
  
  <p>About <code>deps.lock</code> file: it can be removed after removing bundles, than issue:</p>
  
  <pre><code>php bin/vendors update
  </code></pre>
  
  <p>and i should be recreated. It maintains the git version id checked out, for each bundle.</p>
