jngo -- The unhealthily compressed Django application.
Usage: ./jngo.py
Assuming a working install of Django (http://djangoproject.com/) and SQLite
(http://sqlite.org), this script can be executed directly without any other
preparations -- you don't have to do `setup.py install`, it doesn't
need to be on your Python path, you don't need to set DJANGO_SETTINGS_MODULE,
you don't need a webserver. You don't even need content -- the first time it's
run, it will create a SQLite database in the same directory as the script
and populate it with sample pages.
Features:
* Editable content on all pages
* Dynamically generated navigation buttons
* Optional private-access pages
* Optional per-page comments
* RSS feed of latest comments, with autodiscovery

FAQS:
Q: Should I use this as an example of excellent Django coding practices?
A: Um, no. This is pretty much the opposite of excellent Django coding practices.
Q: Why did you do such a terrible thing?
A: At first, it was just a perverse experiment. It ended up being a
good way to refresh my memory on some Django internals, by trying all
kinds of things that broke in weird ways.
