 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.
