+Usage: smartctl-temper-log [device]
+
+Reads 'smartctl -a device' for temperature data.  If a device is not
+sepecified on the commline line then /dev/sda is used.  Writes the
+temperature found to stdout.  Each line contains the unix time in
+seconds since the epoch, the identifier, and the temperature in Celcius.
+
+Before you can use this utility smartctl must be installed and
+configured.  See their documentation for that procedure.
+
+Sample log from a typical hard disk.
