** This tag, as shown, can cause problems (infinite recursion being one) if you don't use it correctly. **
Our internal CMS has a pages app similar to Flatpages, and a "chunks" app similar to [django-chunks](http://blog.clintecker.com/2008/jul/6/django-chunks/). Because most of our other apps are template-tag driven (FAQs, job postings, news, events, etc) I wanted a way to be able to write django template code right into a page or chunk's body from within the django admin.
This tag will let you write django template code into, for example, a Flatpage's content and render it with the current context. So if you had a template tag called "get_latest_news" and wanted to add latest news to a flatpage, just enter this in the flatpage's content:
{% get_latest_news 5 as news %}
{% for article in news %}
<li>{{ article.title }}</li>
{% endfor %}
This ability has proven extremely useful to us. Please note this is just a "summary" snippet to illustrate the concept. Use in a production environment should include more robust error checking.
