OK, fair enough.

Those are useful little utilities and simpler than what I posted. If
something like these had been in the scripts/ directory, then I
wouldn't have spent the time to write yet another script that does
basically the same thing. I get what you are saying, however having
a script to lookup a Kconfig by name or module will be useful to other
people.
