thanks for the input.  I had already figured out that I was not
getting the correct information from the plists.  I was only get the
project plist which was missing inherited projects.  I have changed it
to use code from the version plugin instead.

I 'll look into that function.

That was a line that I did not delete - it is from mergeBuild.

I have removed it, as I also found it earlier and couldn't understand
why it was there.

Here is a (almost) rewritten version of the plugin.
