Utilities
=========
Jinja comes with some utility tags shipped. Those arn't necessary but can help
you with your templates.
Capture Output
==============
Captures output and stores it in a variable::
{% capture as loopdata %}
{% for item in navigation %}
{{ item.caption|escapexml }}
{% endfor %}
{% endcapture %}
The output of the for loop is now stored in the variable ``loopdata``.
This allows the double usage of block tags::
{% capture as title %}{% marker "title" %}{% endcapture %}
{{ title|escapexml }} | My Webpage
{{ title }}
{% marker "body" %}
Modify / Set Variables
======================
``{% define %}`` allows you to set a variable.
Usage::
{% define my_variable "Some Value" %}
You can also apply filters::
{% define escaped content | escapexml %}
