Profiling a Program: Where Does It Spend Its Time?
**************************************************
This manual describes the GNU profiler, `gprof', and how you can use
it to determine which parts of a program are taking most of the
execution time. We assume that you know how to write, compile, and
execute programs. GNU `gprof' was written by Jay Fenlason.
