title: Django admin sites - location of admin.py
body: <p>I am writing django project which has several small apps. I want to use default admin site, so my admin.py will be very simple. Unfortunatelly it doesn't work if I put it to project directory - it has to be in app directory. Now I have two options:</p>
  
  <ul>
  <li><p>Put one admin.py in one of app's directory - it will work but it's logically not correct</p></li>
  <li><p>Put several admin.py files in each app directory (containing only models from certain app)</p></li>
  </ul>
  
  <p>Is there some way to force django to look for this file in project root directory?</p>
