COMMAND NAME:

        STOPWATCH

ABBREVIATION:

        SW

USAGE:

        STOPWATCH START
        STOPWATCH STOP
        STOPWATCH

        The stopwatch command is an implementation of a simple timekeeping
        mechanism.  It keeps track of wall time (NOT cpu time).  STOPWATCH
        START resets the internal stopwatch.  STOPWATCH or STOPWATCH STOP
        (the two forms perform the identical function) prints out the time
        that has elapsed since the last STOPWATCH START command was issued.

EXAMPLE:

        To time a script issue the following command sequence:

                stopwatch start; script 'run.scl'; stopwatch stop

        The amount of elapsed time that the script 'run.scl' used will be
        reported when it terminates.  A word of caution: System
        environmental factors can affect the total time that any specific
        command or script takes to complete.  Such things as memory usage
        and other process load must be taken into account when comparing
        elapsed times of different runs.
