+NAS utils daemon
+================
 
 A small shell-based daemon to control the fan based on NAS temperature. In
 theory it can measure temperature of HDDs too, however hddtemp counts as

+It controls too hdd leds, to make it to blink on disk activity and send harddrive

changelog

+dns-nas-utils (2.0-1)
+  * Added a new daemon to control all others from only one routine.
+  * Added HDD status to send messages to kernel about disk state (standby/active)
+  * Added messages to kernel for the fan daemon to inform about changes.
+  * Added hdd/usb leds blink on hdd/usb changes.

 dns-nas-utils (1.5-1)
   * Force lang to C in order to prevent UTF-8 multibyte error (thanks KiLMaN)

 Description: Miscallaneous scripts for D-Link NASes, DNS-325 and DNS-320
  This package contains:-
-  fan-daemon: Controls the fan based on hdd and board temperature
+  dns-nas-utils: Controls fan based on hdd and board temperature, send 
+                 kernel messages about system temp and hdd status and
+                 handle hdd leds.
   dns_temp: Fetches the temperature of the NAS, either via I2C or serial
