This also added the following entry to the index:

+func_time_stats.stp - Function time statistics
+keywords: function wall-clock time
+
+  The func_time_stats.stp script tracks the wall clock time for each
+  invocation of a function probe listed as the first command line
+  argument. When the script exits it prints out the minimum, average,
+  and maximum times in microseconds. It also prints out a count of
+  times that the function was called.

Which sounds interesting, but doesn't seem to actually exist.
Did you forget to commit it, or isn't it ready yet?

Thanks,

Mark

Hi Mark,

Thanks for pointing that out. I had it in my local tree and "perl ./examples-index-gen.pl" pulled it in. I fixed things up and checked it in for real. I hope that someone finds it useful.
