+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.
