[Spambayes] OptionConfig.py - split into two pieces?

[Skip Montanaro]

In pop3proxy.py I see 

    from OptionConfig import OptionsConfigurator

but OptionConfig.py is at the top level (not in the spambayes package) and
isn't installed.  It looks like both a module and a script.  Perhaps it
should be split in two pieces, a script and an importable module.
