title: Changing existing pages in Agilo/Trac via plugin
body: <p>Is it possible to make changes to an existing page in Trac via a plugin?
  (I am not talking about the wiki, but the ticket system).</p>
  
  <p>I am trying to make a plugin that uses the View Tickets -> Custom Query view and gets the tickets from the resulting table of tickets. The goal is to use these tickets to modify them via a predefined python script, and then optionally print them.</p>
  
  <p>Is this possible via the trac api or would one have to make a whole new page and write that whole query functionality from scratch to get the tickets from the database?</p>
  
  <p>I feel that this is not very clearly documented by Trac, so I hope there are some people with experience in plugin development for trac and/or agilo for trac.</p>
