``format``
==========
The ``format`` filter formats a given string by replacing the placeholders
(placeholders follows the `sprintf`_ notation):
.. code-block:: jinja
{{ "I like %s and %s."|format(foo, "bar") }}
{# outputs I like foo and bar
if the foo parameter equals to the foo string. #}
.. _`sprintf`: http://www.php.net/sprintf
