It doesn't inherit from the library and/or the django app in the way the current site does. With the new setup, I can imagine that you don't inherit from the django app. But not inheriting from the library means you have to do the changelog, bootstrap.py and so double. Perhaps it is unavoidable, but you might want to take another quick look.

(And at least add a warning/note somewhere in the readme or at the top of the `leansite.py` that it doesn't behave like the other three templates).
