/* INTRODUCTION
This package is for timing various operations. Say you need to time
an operation P. You first call clock_init() to set up a clock,
then you can start and stop the clock as you wish, then you
can get the accumulated time with clock_value().
These clocks measure the user CPU time.
<P>
An unusual feature of these clocks is that they can be used
inside of recursive routines. For example, you can start
the clock at the beginning of a recursive routine and stop
it at the end. If you start it 3 times then stop it
three times, it will really stop only on the third call.
This works by a counter of the number of extra
times the clock has been started, and clock_stop() will stop
the clock only when the count is 0. (This feature probably isn't
very useful, and most people can ignore it.)
<P>
Also here are some routines for getting process system/user CPU time,
elapsed wall-clock time, and the time/date.
