Under Unix/X, the following standard X Window System flags are recognized (but not necessarily implemented): -display (1 argument), -geometry (1 argument), -bg (1 argument), -background (1 argument), -fg (1 argument), -foreground (1 argument), -fn (1 argument), -font (1 argument), -iconic (0 arguments), -name (1 argument), -rv (0 argument), -reverse (0 arguments), -rv (0 arguments), -selectionTimeout (1 argument), -synchronous (0 arguments), -title (1 argument), -xnllanguage (1 argument), and -xrm (1 argument).
All X flags must precede all other flags and arguments.
