+* The API provides the P&S power state keys that are updated by the HW Resource 
+* Manager Server. These keys provide up-to-date information on the charging 
+* status, battery level and battery state of the device. Any application may 
+* subscribe to these P&S keys that are updated to receive notifications of 
+* any change in state.
+*
+* This interface relies on the Publish and Subscribe (P&S) interface provided
+* by Symbian. P&S is used by HW Resource Manager to globally publish the power
+* state information.
+*
+* The P&D UID is #KPSUidHWRMPowerState and following keys are provided:
+* - #KHWRMBatteryLevel
+* - #KHWRMBatteryStatus
+* - #KHWRMChargingStatus
