So, since you've already written it, my suggestion may be a little too
little too late.  But anyways...

Boost also has program options library which provides a cross-platform
command line option parser much like getopt on GNU platforms.  I tend to
use it instead of getopt whenever I need a cross-platform command line
options parser.  I don't use getopt because it's not cross-platform.

Perhaps not useful right this moment, but just something to be aware of
in the future when similar needs arise...

And I'm all for your plan, just to be clear.
