# description:       acdcontrol is a program capable of configuring the brightness of \
#                    TFT flat panel displays connected to the PC via USB. \
#                    Activating this "service", your preferred brightness will be read \
#                    from /etc/sysconfig/acdcontrol and set at boot time. \
#                    Currently most Apple Studio, Cinema and Cinema HD Displays are \
#                    supported, as well as some Samsung TFTs.
