display graphs for monitoring hardware temperature

 Psensor is a GTK+ application for monitoring hardware sensors,
 including temperatures and fan speeds.
 .
 It displays a curve for each sensor, alerts user using Desktop Notification
 and Application Indicator when a temperature is too high.
 .
 It can monitor:
  * the temperature of the motherboard and CPU sensors (using lm-sensors).
  * the temperature of the NVidia GPUs (using XNVCtrl).
  * the temperature of the Hard Disk Drives (using hddtemp or atasmart lib).
  * the rotation speed of the fans (using lm-sensors).
  * the sensors of a remote computer (using psensor-server).
