+    ~~~~~~
+
+    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 %}
