+         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.
+
+         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.
