Well, in my dbf.py Record class you can use the names of fields as the slice arguments, instead of
having to remember the offsets. record['full_name':'zip4'] returns a tuple (or a list, I don't
remember) of about 13 fields -- this is especially useful as that block of fields might not be in
the same place in each table.
