-	\brief A timer class.
+	\brief A simple class used to time events like a stop watch.
 
-	This class provides method to time events. The interface is designed to 
-	behave like a physical stopwatch. It is especially useful for debugging 
-	certain parts of your code, since it can behave like a 'cheap' profiler. 
+	The interface of this class is designed to behave like a physical
+	stop watch. It is useful for debugging parts of your code acting as a
+	quick and dirty profiler.
+
+	To use this class first create a BStopWatch object, this starts the timer
+	going. You may call Suspend() and Resume() to start and stop the stop
+	watch. Call ElapsedTime() to get the current timer count at any time. You
+	may call Lap() to start a new lap (up to 10 laps are supported) or call
+	Reset() to reset the timer back to 0 clearing all lap info. When the
+	object is destroyed the timing information is streamed to standard out
+	unless you set the \a silent parameter to \c true in the constructor.

+	\brief Constructs a BStopWatch object and starts the timer.
 
-	The constructor creates a clean BStopWatch object. This object
-	can be given a name. As soon as the object is created, the time
-	will start ticking away. This class is designed to be usuable as a primitive
-	profiling tool.
+	This method creates a new BStopWatch object. As soon as the object is
+	created the timer starts ticking away.
 
-	If you are profiling your code with this class, pass true as the
-	\a silent parameter. Whenever the object is destroyed, information on
-	the elapsed time will be streamed to standard output.
+	If you are profiling your code with this class, pass \c true to the
+	\a silent parameter. Doing so causes elapsed time information to be
+	streamed to standard output when when the object is destroyed.
 
-	\param name The name you want to give this object. You may pass \c NULL.
-	\param silent Pass \c true if you want to use this object as a simple

+	\param name The name of the stop watch. You may pass \c NULL to create an

+	\param silent Pass \c true to suppress time information from streaming to
