Class Description

                                                                      
 TStopwatch                                                           
                                                                      
 Stopwatch class. This class returns the real and cpu time between    
 the start and stop events.                                           
                                                                      


TStopwatch()
 Create a stopwatch and start it.

void Start(Bool_t reset)
 Start the stopwatch. If reset is kTRUE reset the stopwatch before
 starting it. Use kFALSE to continue timing after a Stop() without
 resetting the stopwatch.

void Stop()
 Stop the stopwatch.

void Continue()
 Resume a stopped stopwatch. The stopwatch continues counting from the last
 Start() onwards (this is like the laptimer function).

Double_t RealTime()
 Return the realtime passed between the start and stop events. If the
 stopwatch was still running stop it first.

Double_t CpuTime()
 Return the cputime passed between the start and stop events. If the
 stopwatch was still running stop it first.

Double_t GetRealTime()

Double_t GetCPUTime()

void Print(Option_t *)
 Print the real and cpu time passed between the start and stop events.
