win32com.client documentation?

I am a unix person, not new to Python, but new to Python programming
on windows. Does anyone know where to find documentation on
win32com.client? I have successfully installed this module and
implemented some example code. But a comprehensive explanation of the
objects and methods available is nowhere to be found. I have been
able to find a somewhat out-of-date O'Reilly book, nothing more.

I want to be able to script the creation of Excel spreadsheets and
Word documents, interract with Access data bases, and so forth.
