     ~~~~~~
 
     Jinja2 is a template engine written in pure Python.  It provides a
     Django inspired non-XML syntax but supports inline expressions and
     an optional sandboxed environment.
 
     Nutshell
     --------
 
     Here a small example of a Jinja2 template::
 
         {% extends 'base.html' %}
         {% block title %}Memberlist{% endblock %}
         {% block content %}
           <ul>
           {% for user in users %}
             <li><a href="{{ user.url }}">{{ user.username }}</a></li>
           {% endfor %}
           </ul>
         {% endblock %}
