title: The correct place to put a markdown extension file in a django project?
body: <p>I've created a markdown extension file (called mdx_xxx.py) for a django project I'm working on but I can't really decide where to put it.</p>
  
  <p>The documentation says that the file should reside on the PYTHONPATH and I've seen several blog posts inviting to just put the file in the root directory of the project.</p>
  
  <p>However, that seems like an odd place to me as I would rather see it in the related application directory but then it's not on the PYTHONPATH anymore.</p>
  
  <p>Could some experienced django programmer shed some light on this issue?</p>
  
  <p>Thanks</p>
