     58  This table describes the call tree of the
program, and was sorted by
     59  the total amount of time spent in each
function and its children.
     60
     61  Each entry in this table consists of several
lines.  The line with the
     62  index number at the left hand margin lists
the current function.
     63  The lines above it list the functions that
called this function,
