+.Nd apple brightness/volume button control
+.Sh SYNOPSIS
+.Cd "abtn at adb?"
+.Sh DESCRIPTION
+The 
+.Nm
+driver allows you to dim the brightness of your display.  This driver only
+currently recognizes the dim and brightness button.  Sound, numlock and
+eject buttons are also handled by this driver but are silently ignored.
+.Sh SEE ALSO
+.Xr adb 4, 
+.Xr aed 4
+.Sh AUTHOR
+abtn was written by Tsubai Masanari for NetBSD.
+.Sh BUGS
+The bright/dim buttons currently don't work on new 2001 iBooks.  It's best
+to just disable the driver to avoid freeze ups when pressing these buttons.
