                                                This program requires the sonypi module to be loaded, and that you have
                                                correctly configured /dev/sonypi.

                                                Th4nks and gr33ts to Henrik Jonsson and his l33t C sk1llz, without whoM I would
                                                still be struggling to get this to compile.
