 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.
