-  \brief The AlarmServer class provides alarms to be scheduled.
+  \brief The AlarmServer class allows alarms to be scheduled and unscheduled.
+
+    Applications can schedule alarms with addAlarm() and can
+    unschedule alarms with deleteAlarm(). When the time for an alarm
+    to go off is reached the specified \link qcop.html QCop\endlink
+    message is sent on the specified channel (optionally with
+    additional data).
+
+    Scheduling an alarm using this class is important (rather just using
+    a QTimer) since the machine may be asleep and needs to get woken up using
+    the Linux kernel which implements this at the kernel level to minimize
+    battery usage while asleep.
 
-  Applications which wish to be informed when a certain time instant
-  passes use the functions of AlarmServer to request so.
