Renaming an import

[Rob Gaddi]

I'm trying to figure out how to rename an import globally for an entire package. 
  Something like:

pkg/__init__.py:
     import graphing_module_b as graph

pkg/foobar.py:
     from .graph import plot, axis

The point being that, if at some point I decide to change from graphing_module_b 
to graphing_module_a, that decision is made at a single central point in my 
package rather than scattered through 30 different import statements in a dozen 
files.

Any ideas?
