call graph profile:

          The sum of self and descendents is the major sort

          for this listing.

          function entries:

index     the index of the function in the call graph

          listing, as an aid to locating it (see below).

%time     the percentage of the total time of the program

          accounted for by this function and its

          descendents.

self      the number of seconds spent in this function

          itself.

descendents

          the number of seconds spent in the descendents of

          this function on behalf of this function.

called    the number of times this function is called (other

          than recursive calls).

self      the number of times this function calls itself

          recursively.

name      the name of the function, with an indication of

          its membership in a cycle, if any.

index     the index of the function in the call graph

          listing, as an aid to locating it.

          parent listings:

self*     the number of seconds of this function's self time

          which is due to calls from this parent.

descendents*

          the number of seconds of this function's

          descendent time which is due to calls from this

          parent.

called**  the number of times this function is called by

          this parent.  This is the numerator of the

          fraction which divides up the function's time to

          its parents.

total*    the number of times this function was called by

          all of its parents.  This is the denominator of

          the propagation fraction.

parents   the name of this parent, with an indication of the

          parent's membership in a cycle, if any.

index     the index of this parent in the call graph

          listing, as an aid in locating it.

          children listings:

self*     the number of seconds of this child's self time

          which is due to being called by this function.

descendent*

          the number of seconds of this child's descendent's

          time which is due to being called by this

          function.

called**  the number of times this child is called by this

          function.  This is the numerator of the

          propagation fraction for this child.

total*    the number of times this child is called by all

          functions.  This is the denominator of the

          propagation fraction.

children  the name of this child, and an indication of its

          membership in a cycle, if any.

index     the index of this child in the call graph listing,

          as an aid to locating it.

          * these fields are omitted for parents (or

          children) in the same cycle as the function.  If

          the function (or child) is a member of a cycle,

          the propagated times and propagation denominator

          represent the self time and descendent time of the

          cycle as a whole.

          ** static-only parents and children are indicated

          by a call count of 0.

          cycle listings:

          the cycle as a whole is listed with the same

          fields as a function entry.  Below it are listed

          the members of the cycle, and their contributions

          to the time and call counts of the cycle.
