title: Extending Handlebars.js templates
body: <p>Is there a way to extend templates like in Django? My base template has a header that only needs to be a few pages. I'd like to change that for the the other templates.</p>
  
  <p>Something similar to </p>
  
  <pre><code>{% extends "base.html" %}
      ...
  {% endblock %}
  </code></pre>
  
  <p>I'm using Ember.js. </p>
