[python-win32] win32com v.s. win32comext?

[aurora]

I use win32com.shell. There are something special going on I don't  
understand. Notice the commands below. I imported win32com.shell. But the  
module is being loaded from win32comext\shell\__init__.pyc.

>>> import win32com.shell
>>> win32com.shell
<module 'win32com.shell' from  
'c:\Python24\Lib\site-packages\win32comext\shell\__init__.pyc'>

What is the mechanism to make this happen? I am digging into this because  
when I try to use py2exe, I got this error:

The following modules appear to be missing
['win32com.shell']

I thought it may be related.
