   This table describes the call tree of the program, and was sorted by
   the total amount of time spent in each function and its children.
  
   Each entry in this table consists of several lines.  The line with the
   index number at the left hand margin lists the current function.
   The lines above it list the functions that called this function,
   and the lines below it list the functions this one called.
   This line lists:
       index	A unique number given to each element of the table.
  		Index numbers are sorted numerically.
  		The index number is printed next to every function name so
  		it is easier to look up where the function in the table.
  
       % time	This is the percentage of the `total' time that was spent
  		in this function and its children.  Note that due to
  		different viewpoints, functions excluded by options, etc,
  		these numbers will NOT add up to 100%.
  
       self	This is the total amount of time spent in this function.
  
       children	This is the total amount of time propagated into this
  		function by its children.
  
       called	This is the number of times the function was called.
  		If the function called itself recursively, the number
  		only includes non-recursive calls, and is followed by
  		a `+' and the number of recursive calls.
  
       name	The name of the current function.  The index number is
  		printed after it.  If the function is a member of a
  		cycle, the cycle number is printed between the
  		function's name and the index number.
  
  
   For the function's parents, the fields have the following meanings:
  
       self	This is the amount of time that was propagated directly
  		from the function into this parent.
  
       children	This is the amount of time that was propagated from
  		the function's children into this parent.
  
       called	This is the number of times this parent called the
  		function `/' the total number of times the function
  		was called.  Recursive calls to the function are not
  		included in the number after the `/'.
  
       name	This is the name of the parent.  The parent's index
  		number is printed after it.  If the parent is a
  		member of a cycle, the cycle number is printed between
  		the name and the index number.
  
   If the parents of the function cannot be determined, the word
   `<spontaneous>' is printed in the `name' field, and all the other
   fields are blank.
  
   For the function's children, the fields have the following meanings:
  
       self	This is the amount of time that was propagated directly
  		from the child into the function.
  
       children	This is the amount of time that was propagated from the
  		child's children to the function.
  
       called	This is the number of times the function called
  		this child `/' the total number of times the child
  		was called.  Recursive calls by the child are not
  		listed in the number after the `/'.
  
       name	This is the name of the child.  The child's index
  		number is printed after it.  If the child is a
  		member of a cycle, the cycle number is printed
  		between the name and the index number.
  
   If there are any cycles (circles) in the call graph, there is an
   entry for the cycle-as-a-whole.  This entry shows who called the
   cycle (as parents) and the members of the cycle (as children.)
   The `+' recursive calls entry shows the number of function calls that
   were internal to the cycle, and the calls entry for each member shows,
   for that member, how many times it was called from other members of
   the cycle.
