++ This driver provides support for the Apple System Management
++ Controller, which provides an accelerometer (Apple Sudden Motion
++ Sensor), light sensors, temperature sensors, keyboard backlight
++ control and fan control.
++
++ Only Intel-based Apple's computers are supported (MacBook Pro,
++ MacBook, MacMini).
++
++ Data from the different sensors, keyboard backlight control and fan
++ control are accessible via sysfs.
++
++ This driver also provides an absolute input class device, allowing
++ the laptop to act as a pinball machine-esque joystick.
