I'm afraid this can't be put into practice. (User says which hardware
and protocols he needs to be supported, scripts magically assemble a
suitable configuration.)

I think
- sensibly modularize our software,
- tell the user which software components there are,
- what they are for,
- how they depend on each other,
- make it easy enough for the user to navigate in the dependency
graph,
- provide fundamental safeguards and checks for a proper software
configuration
is the best we can do.
