    ~~~~~~

    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 %}
