Ah, yes, this seems exactly right. I have switched to different packages
for each model now, so to test it properly I need to go back to previous
set-up (not sure which one I prefer now ;).

However, I wonder if this code in __init__ can be parametrized somehow.
All it needs as input is the list of models in the package.
Maybe the list of models may be calculated by looking into
the custom classes -- if model for this class is unknown yet, then it is
added to the list...

Otherwise, I could live with having to make such a modification=20
manually,
but I would need to know about it (if I did know this last night I would
have gained a few hours ;-) Thus, maybe at least an FAQ entry, such as:

How can I automatically generate one package from several models?

Thanks!
