I am still struggling with how to do this client-side without
having p4config files all over the place; c.f. my post about
p4config being mandatory.

So then I started to wonder whether it could be done server-side,
e.g. with a submit trigger.  At submit time, you know (1) the
changelist number, and (2) that you are "cleanly synced".  I have a
feeling, though, that it's not possible to edit a file in a trigger
and "p4 submit" it.  Or is it?  

Is there a server side solution to this?

Thanks,
