Well, I second tilly's requirements in this post.

My requirements to a configuration module are:

1. Allow nested categories.
2. Allow list values (e.g. users=tinkywinky,dipsy,lala,po).
3. Warn on access attempt to undefined variables.

I am unfamiliar with have these requirements are covered, but thanks to excellent response from the monks, I have a good starting point for finding the way.

Thanks.

Andreas
