title: Trac, how to organize pages hierarchically?
body: <p>I use <a href="http://trac.edgewall.org" rel="nofollow">trac</a> to manage my projects and I'd like to organize wiki pages the same way trac project does, i.e. by category, subcategory, etc. <a href="http://trac.edgewall.org/wiki/TitleIndex" rel="nofollow">TitleIndex</a> page on trac site gives a good explanation of the result I want to obtain.</p>
  
  <p>How do I achieve this?</p>
