+Linux watchdog timer daemon

+This service periodically writes to /dev/watchdog - in the event

+For this to work, a kernel driver for the aformentioned device needs
+to be loaded.  The module may be found in:
+  /lib/modules/`uname -r`/kernel/drivers/char/watchdog
+
+It can be configured to try and fix things (such as networking)
+before triggering a reboot. As 'repair.sh' may be able to do.
+See the examples included in /usr/doc/watchdog-5.6/examples
+
+This package also contains the 'wd_keepalive' program by Marcel Jansen
+which "can be run during critical periods when the normal watcdog
+shouldn't be run. It will read from the same configuration file;
+it will do no checks but will keep writing to the device.
+
+To enable the watchdog: make sure a kernel module gets loaded for it
+(at boot) such as the 'softdog' or an actual hardware driver... 
+Then add the following to rc.local:
+
+# Start the watchdog timer deamon
+if [ -x /etc/rc.d/rc.watchdog ]; then
+  /etc/rc.d/rc.watchdog start
+fi

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
