[Puppet Users] Catalogue graph building; nodes *then* edges?

Unfortunately, we have many dozen modules and hundreds of classes, with a
disjoint set of people using and maintaining them. What you suggest simply
isn't practical. :-( Asking the human element to keep track of what
relevant changes have been made, and alter scripts accordingly, is not only
error-prone but the sort of thing computers are supposed to do for us..

Thanks, though!
