Use Django Fixtures to Automatically Load Data when You Install an App

First, load some data via the admin that should always be there when someone installs the app.

Next, dump that data out into JSON format into a fixture:

$ ./manage.py dumpdata [app_name] > [app_name]/fixtures/initial_data.json

An asynchronous task manager.

This is a simple implementation for background task handing. No guarentees are
provided for task execution.

This was developed in the course of the work don for the victims project and 
that version is available at

Common Software Uses

• Publishing (Draft->Approved->Published->Expired->Deleted)
