Couldn't we do it the other way around and generate the code that reads
and writes the config entries from the XML file? Then we have only one
place where the config options are specified and automatically get a
nice C++ class for the configuration which is convenient to use in an
application. We could even try to automatically generate code for the
configuration dialogs, at least for some standard types. This could
significantly improve consitency across different apps.
