    A lot of the work on the code base winds up being 'maintainance' like
    this.  It does make our jobs a lot easier down the road when we decide
    to take that final step to actual conformance.

    It's also a good way to break up a large coding job into smaller more
    easily handled pieces.  Once you get rid of all the easy-to-do
    low-hanging fruit the hard bits will seem less hard.
