+       help
+         This driver makes the mail LED accessible from userspace
+         programs through the leds subsystem. This LED have three
+         known mode: off, blink at 0.5Hz and blink at 1Hz.
+
+         The driver supports two kinds of interface: using ledtrig-timer
+         or through /sys/class/leds/clevo::mail/brightness. As this LED
+         cannot change it's brightness it blinks instead. The brightness
+         value 0 means off, 1..127 means blink at 0.5Hz and 128..255 means
+         blink at 1Hz.
+
+         This module can drive the mail LED for the following notebooks:
+
+               Clevo D410J
+               Clevo D410V
+               Clevo D400V/D470V (not tested, but might work)
+               Clevo M540N
+               Clevo M5x0N (not tested, but might work)
+               Positivo Mobile (Clevo M5x0V)
+
+         To compile this driver as a module, choose M here: the
+         module will be called leds-clevo-mail.
