Wow! How did you find that one out? I've searched the wix docs and
couldn't find anything about that!

We could simply generate the version number with our SubWCRev tool, i.e.
the fourth part of the version number would then be the revision number.

I changed the build script so that the package and product ids now have
the ??? in it and therefore will be created automatically at build time.
Also, it calls SubWCRev before building the msi's to fill in the version
number in the wxs file. I think this should do it for the nightly builds...

Thanks a lot for your help!
