migrating to packages

[Gerardo Herzig]

Hi all. I have a single file with several classes, wich i want to 
separate into several packages.
The big file is named, say MYCLASES, and contains a class named 
A(object), and B(A).

We have been using this MYCLASES in the
from MYCLASES import B syntax, but i cant reproduce this syntax using 
packages. Im forced to write from PACKAGE.B import *, and if that means 
i have to touch so many files, that would really be a problem to me. 
There is (i cant find it yet) a place where i can read about that kind 
of package 'migration' situation?

Because i *really* want to keep the FROM PACKAGE import B syntax.

Thanks!
Gerardo
