"Since App Engine does not support Django models, leave all DATABASE_* settings set to an empty string. The authentication and admin middleware and apps should be disabled since they require Django models. The functionality these provide is covered by the App Engine Users API and Admin Console respectively. Sessions also depend on Django models and must be disabled as well. Finally, you need to set the path to your template directory dynamically."
I'm curious, does this mean that once you do their initial steps, you could run any existing Django application to Google App Engine?
