[Zconfig] Overlaying multiple config files

[Moore, Paul]

I have an application suite which currently uses ConfigParser for
configuration information. The config is built up in 3 parts, from
some hard-coded defaults, then from a suite-specific ini file
(suite.ini) and then from a further application-specific ini file
(app.ini). I'd like to do something similar with ZConfig, but I'm not
clear how to.

Defaults are easy - these can be added to the schema. But I can't see
how to overlay 2 files. It looks like I probably need to call loadFile
on a loader object multiple times, but I'm not sure how.

I tried creating an explicit loader object and calling loadFile()
twice, but that seems to replace the whole config rather than merging
the two.

I'm clearly missing something, as I'd have thought this should be
reasonably easy. Can anyone help?

Thanks,
Paul.
