How to call a function when a project starts.

Hi Everyone:

I would like to call a function when my project starts, basically I want to call a do_something() when I run python manage.py runserver. However, when I put it into settings.py, it gets called twice, but I only want it to execute once.

Is there a good way to do it.

Thanks
