title: How to export Trac to Github Issues
body: <p>We use Trac for an open-source project I'm working on. I'd like to export all of our open tickets to Github's Issues. I've found a couple small scripts that might do it, but I was wondering if anyone has done this and has suggestions.</p>
  
  <p>Ideally, it would convert trac's description syntax to markdown and also export metadata like milestone information, but even a simple, working export is probably okay.</p>
