Sebastian, all,
This is a fantastic bit of work. I am playing around with it and will see
where I get to.

I have found that to build out, just as in agile development, there should
be something (a framework) that touches all bases. Only then can I find my
way around and add where needed.

Interestingly I looked at Kiwi and found myself wishing for the modularised
approach I think you have achieved here.
