title: How do I use Django's template extends variable?
body: <p>The django <a href="http://docs.djangoproject.com/en/dev/ref/templates/builtins/#extends" rel="noreferrer">template doc</a> mentions the following for extending templates:</p>
  
  <pre><code>{% extends variable %}
  </code></pre>
  
  <p>Where do I define the variable?  Is it from the views.py?</p>
