Usage: plplot-test-interactive.sh [OPTIONS]

Options:
   [--device=DEVICES_LIST]
       where DEVICES_LIST is one of more devices specified as a
       blank-delimited string (e.g., --device=xwin or
       --device="qtwidget extqt").  Note each specified device must be
       taken from the following list of eligible interactive devices:

       xwin, tk, xcairo, wxwidgets, qtwidget, extcairo or extqt.

   [--help]

Environment variables:
   DEVICES_LIST can be used to specify the device(s).
   This environment variable is overridden by the option --device.

N.B. All members of DEVICES_LIST (whether specified by the
DEVICES_LIST environment variable or by the --device option _must_ be
configured.  If neither the environment variable or --device option is
specified, then every _configured_ device from the above list is used.
