title: Django: Difference between BASE_DIR and PROJECT_ROOT?
body: <p>From settings.py:</p>
  
  <pre><code>BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
  PROJECT_ROOT = os.path.dirname(os.path.abspath(__file__))
  </code></pre>
  
  <p>What's the difference between these two?</p>
