I don't think so ATM. The Centipede multi-project in one module thing 
works only ATM for a single centibuild.l

Hmmm...

Something missing in the descriptor.

The problem with the current multi-project-in-module approach is that it 
uses only one centibuild file, which *starts* the process. Hence even if 
we make the multiproject system get the right buildfile, we still need 
to tell centipede which buildfile to start with, and which project. 
Bleah. :-P

So real multiproject builds should be done with Gump, that's all. What 
we have now is a short-circuit that works for one centibuild file and in 
the same module.

It's becoming IMHO more evident that the best thing, as we said some 
days ago, is to zap it and use an external system to drive multiproject 
builds.

If we want we can still do it with the code we have, with a new cent 
script that calls that code, but the best thing is to use Gump and 
that's all.

No?
