- * ALGORITHM
-
- Breezed scans the temperatures every 5s and sets the fan speed
- according to a series of thresholds.
-
- Unfortunately, if the fan speed is set directly according to these
- temperature thresholds, it creates oscillations: The fan goes up,
- temperature goes down, hence fan goes down, temperature goes up,
- etc.
-
- To mitigate such phenomenons, the daemon waits at least 30s after
- the last change before reducing the fan speed, and the actual
- thresholds to decrease the fan speed are two degrees below the
- provided thresholds, which are used when increasing the fan
- speed. This creates a stability area of two degrees, which seems to
- be enough. Please let me know if you have problem with the
- resulting overall behavior.
-
- See the man page for details about the arguments and configuration
- file.

* NOTES
- I wrote this daemon for my personal usage on a X61s, and using it
- may damage your hardware.

On Thinkpads you have to allow the module thinkpad_acpi to set the
fan speed, which is not allowed by default in Debian. To do so, you
have to have a file /etc/modprobe.d/thinkpad_acpi.modprobe
