A Django Template tag for including files that you don't want to parse as templates

Straight Include template tag by @HenrikJoreteg

Django templates don't give us any way to escape template tags.

So if you ever need to include client side templates for ICanHaz.js (or anything else that
may confuse django's templating engine) You can is this little snippet.

Just use it as you would a normal {% include %} tag. It just won't process the included text.

It assumes your included templates are in you django templates directory.

Usage:

{% load straight_include %}

{% straight_include "my_icanhaz_templates.html" %}
