DESCRIPTION
       fltk-options is a tool that allows you to access and change settings
       related to the user interface in applications built with FLTK. These
       settings will be applied when the program is launched. They can be set
       at the system level or by the individual user. User settings take
       precedence over system settings.

       -Soption[=value]
            Change or print system wide option.

            Change or print user option. Values can be "0" or "OFF" to clear,
            or "1" or "ON" to set the option. The value "-1" or "DEFAULT" sets
            the option to its default value.  If no value is given, the
            current setting is returned as "-1", "0", or "1".
