Breezed is a small daemon to control the speed of the fan,
   depending on the current temperature of the computer. I have tested
   it only on a Thinkpad X61s.

 * INSTALLATION

   Before installing, you must have a configuration file in
   /etc/breezed.conf.

   Only one is currently provided in the archive, and it corresponds
   to the settings _I_ picked for _my_ Lenovo X61s. I have no idea if
   these settings are safe on this laptop (I guess so, since I have
   been using them for a few months now and it works perfectly), and I
   suspect they are not safe for another laptop. If you want to give
   it a try, just

     cp breezed_Lenovo_X61s.conf /etc/breezed.conf

   Then, you can install the daemon simply with

     make install

   and uninstall it with

     make uninstall

   See the man page for details about the algorithm, arguments and
   configuration file.

 * NOTES

   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
   containing

   ---------------------------- snip snip -------------------------------
   options thinkpad_acpi fan_control=1
   ---------------------------- snip snip -------------------------------
