+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.
