title: How to get list of all routes of a controller in Symfony2?
body: <p>I have a controller which implements all <strong>routes/URL(s)</strong>.
  I had the idea to offer a generic index over all help-pages.</p>
  
  <p>Is there a way to get all routes defined by a controller (from within a controller) in <code>Symfony2</code>?</p>
