That is quite a lot of stuff... You mention csm already, which does
most of this, but for packaging eggs I think this is a bit too much
automatic processing for my taste. I don't think such a feature belongs
into the core system, but a preprocessor (perhaps by scavenging code
from csm) or a mode for csm to emit egg files might be appropriate.
