title: Is it possible to have custom keywords in trac syntax highlighting?
body: <p>As we all know, Trac has the ability to use <a href="http://trac.edgewall.org/wiki/WikiProcessors" rel="nofollow">WikiProcessors</a> to apply some syntax highlighting on code used in tickets etc.</p>
  
  <p>Now, I have this C application that is full of custom types, macros etc. In Vim, I could simply create a syntax file, store it under <code>syntax/after/c/myproject.vim</code> and &ndash; tadaaaah &ndash; my editor knows my keywords.</p>
  
  <p>Is there such a possiblity for the Trac syntax highlighting (i.e. can I define custom keywords somehow)?</p>
