is there a util.py to automate renaming a Django app?

[MW]

Hi,

I want to rename a Django app.

Google search shows it's not quite a easy task, e.g. I found this:

http://stackoverflow.com/questions/8408046/how-to-change-the-name-of-a-django-app

I just wonder if there is a util.py to automate renaming a Django app?

Thx!
