 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.
