That's OK except that it doesn't associate the different sections in
any way, I need another level which includes these to indicate that
these are values read from the ADC.  There's another collection of
config data for values read from the 1-wire bus.

I guess I could have two config files, one for ADC and one for 1-wire.

In fact I think that's the best approach so far.  Ini format files are
human readable (and more to the point editable), I can store them in
the same directory as the database so they will get carried around
with the data and the configparser module is built-in.
