startforum overwrites existing settings.py

edit

When installing askbot over an existing Django project it asks

Where to deploy (in which directory)?

which appears to want the project directory.

Given the absolute path to the project directory it immediately overwrites settings.py, urls.py, manage.py and __init__.py

I expected it to give me instructions on how to adjust the existing settings and urls files, which is what the startform source seems t imply it should do.
