Good point.  Is the core API documented anywhere?  I can't tell what
is intended to be part of the API and what is accidentally exposed by
the implementation.  

Some particulars:

The getopt code is probably the most complex argument processing code
I've ever seen.  I've got no idea if I've preserved backwards
compatibility where necessary.

Does it mean we need to support all the optional verbose keyword args
even though they will be ignored?
