Usage: ./config [--devdir=\"dir\"] [--prefix=\"prefix\"] [--help]

Options:
     --devdir=DIR   Set the path where QJoyPad will look for your joystick
                    devices to be DIR. If your devices are /dev/js0, /dev/js1,
                    etc., this should be just \"/dev\". By default, this is
                    /dev/input.
 
     --prefix=DIR   Set the path where QJoyPad and its components will be
                    installed. By default, this is /usr/local.
 
     --plain_keys   Force QJoyPad to use standard XWindows keynames without
                    filtering them for appearance. This will make displays
                    less attractive and readable, but will save processor power
                    and ensure that you see the right names for keys you press.
                    
     --install-dir=DIR  Sets an optional installation path that will be prepended
                        to prefix during installation.
     --debug        Causes Qjoypad to spit out debugging messages (debug messages
                    will be  compiled in; to get rid of the messages you'll have
                    to recompile).
    --qmake4bin=EXEC   Overrides the qmake executable used by this script.
	EXEC may be relative to PATH or an absolute pathname.
    --help          Show this message.
