Thanks for responding 7stud.  However, I'm not clear on how this will solve
my problem.  By typing -l, I'll still execute this option.  I've also come
across the case where if I have an option for --migrate VERSION (required
input) and I use the option -m, I'll get an error because the version was
not included.  However, if I use -mig, I get no error and a version value of
nil is passed...

Please help!
