+Contact: Richard Purdie <rpurdie@rpsys.net>
+Description:
+ Set the brightness of the LED. Most LEDs don't
+ have hardware brightness support so will just be turned on for
+ non-zero brightness settings. The value is between 0 and
+ /sys/class/leds/<led>/max_brightness.

+What: /sys/class/leds/<led>/trigger
+Date: March 2006
+KernelVersion: 2.6.17
+Contact: Richard Purdie <rpurdie@rpsys.net>
+Description:
+ Set the trigger for this LED. A trigger is a kernel based source
+ of led events.
+ You can change triggers in a similar manner to the way an IO
+ scheduler is chosen. Trigger specific parameters can appear in
+ /sys/class/leds/<led> once a given trigger is selected.
