automatic from module import * expansion

[Keith Jackson]

Does anybody know of a tool that will take a module as input, look for 
any wildcard imports, and then identify what symbols in the module come 
from which wildcard import? It could then expand out the from module 
import * to from module import foo, bar. It might need to ask the user 
on this, since they might want the wildcard import for something 
special, but it would still be *much* nicer then expanding the imports 
out by hand.

Apologies ahead of time if I've missed something obvious. I did spend 
some quality time with google, and couldn't find anything.
cheers,
