I can do configuration files, but it doesn't seem to matter when I do
one versus the other. Once it is specified in the configuration file,
that one takes precedence.

Perhaps there is some parse option I can use to override options? I'd
like to do configuration file first, then override with CLI, if
possible.

Of course where po::value<vector<something>>() is involved, that could
 get interesting.

Thank you...
