Now, it's huge and split across multiple files so it's harder to 
search, the class browser won't work, and the full source 
cannot be brought up immediately using just the module name.
The svn annotations and history are munged-up.  The components 
were highly interdependent so now every file has to start with a 
set of cross-imports.  Well, at least the __init__.py is not full of code.
That's something.

FWIW, it wasn't that big (approx 2500 lines).
The argparse, difflib, doctest, pickletools, pydoc, tarfile modules
are about the same size and the decimal module is even larger.  
Please don't split those.
