Hi Michal,

Thank you very much for your reviews!

I like the idea. CONFIG_* strings at least should be easy to identify in
the source code indeed. I'll also have to find all the parameters
referred to in Kconfig files (namely as dependencies), but this should
be worth the effort.

The whole program will be a bit more complex, but it will be orders of
magnitude faster!

Thanks again,

Michael.
