 %description
-Xfce Power Manager uses the information and facilities provided by HAL to 
-display icons and handle user callbacks in an interactive Xfce session.
-Xfce Power Preferences allows authorised users to set policy and change 
-preferences.

+Xfce4 Power Manager manages the power sources of the computer and connected devices
+(wireless mice, keyboards, media players etc.). It also allows users to control
+the display backlight brightness and set power-saving modes for displays and monitors.
+In addition, xfce4-power-manager provides a set of freedesktop-compliant DBus interfaces to
+inform other applications about current power level so that they can adjust their power consumption.
