Get rid of example command line options
Get rid of example command line options

Everett mentioned cleaning up the example code and I'd like to
start this by removing the command line options.  There is a lot
of complexity there I'd sooner not maintain.  I'm pretty sure
some of it is broken.  It is also different than other CLIs.
Use OCC.
