 This is a Linux ACPI driver for the IBM ThinkPad laptops. It supports
 various features of these laptops which are accessible through the
-ACPI framework but not otherwise supported by the generic Linux ACPI
-drivers.

+The ibm-acpi kernel driver can be programmed to revert the fan level
+to a safe setting if userspace does not issue one of the fan commands:
+"enable", "disable", "level" or "watchdog" within a configurable
+ammount of time.  To do this, use the "watchdog" command.

+Interval is the ammount of time in seconds to wait for one of the
+above mentioned fan commands before reseting the fan level to a safe
+one.  If set to zero, the watchdog is disabled (default).  When the
+watchdog timer runs out, it does the exact equivalent of the "enable"
+fan command.
+
+Note that the watchdog timer stops after it enables the fan.  It will
+be rearmed again automatically (using the same interval) when one of

+through means other than the "enable", "disable", and "level" fan
+commands.

-Example Configuration
----------------------
-
-The ACPI support in the kernel is intended to be used in conjunction
-with a user-space daemon, acpid. The configuration files for this
-daemon control what actions are taken in response to various ACPI
-events. An example set of configuration files are included in the
-config/ directory of the tarball package available on the web
-site. Note that these are provided for illustration purposes only and
-may need to be adapted to your particular setup.
-
-The following utility scripts are used by the example action
-scripts (included with ibm-acpi for completeness):
-
-	/usr/local/sbin/idectl -- from the hdparm source distribution,
-		see http://www.ibiblio.org/pub/Linux/system/hardware
-	/usr/local/sbin/laptop_mode -- from the Linux kernel source
-		distribution, see Documentation/laptop-mode.txt
-	/sbin/service -- comes with Redhat/Fedora distributions
-	/usr/sbin/hibernate -- from the Software Suspend 2 distribution,
-		see http://softwaresuspend.berlios.de/
-
-Toan T Nguyen <ntt@physics.ucla.edu> notes that Suse uses the
-powersave program to suspend ('powersave --suspend-to-ram') or
-hibernate ('powersave --suspend-to-disk'). This means that the
-hibernate script is not needed on that distribution.
-
-Henrik Brix Andersen <brix@gentoo.org> has written a Gentoo ACPI event
-handler script for the X31. You can get the latest version from
-http://dev.gentoo.org/~brix/files/x31.sh
-
-David Schweikert <dws@ee.eth.ch> has written an alternative blank.sh
-script which works on Debian systems. This scripts has now been
-extended to also work on Fedora systems and included as the default
-blank.sh in the distribution.
