* { "filename", require_arg, 'f' },
* { "append", no_arg, 'a' },
* { "width", require_arg, 'w' },
* { NULL, 0, 0 }

* Long named options can have arguments specified as either:
*
* ``--param=arg'' or ``--param arg''
*
* Short named options can have arguments specified as either:
*
* ``-w80'' or ``-w 80''
*
* and can have more than one short named option specified at one time:
*
* -aw80
*
* in which case those options which expect an argument need to come at the
