But very slow, complex and not enough powerful:
The tools should have extensive knowledge about Kconfig,
and the CONFIG_ dependencies; it should handle a lot of
structures (text/binary; line/record oriented; etc.), which
it is not easy in shell (awk, od, sed with extended regexp are
not core utilities).

So my suggestion is: do it in a high level language, to find and
stabilize the design, and then integrate it in kconfig later (using
C).
