+Large complex programs are composed of many small routines
+that implement abstractions for the routines that call them.
+To be useful, an execution profiler must attribute
+execution time in a way that is significant for the 
+logical structure of a program
+as well as for its textual decomposition.
+This data must then be displayed to the user
+in a convenient and informative way.
+The \fBgprof\fP profiler 
+accounts for the running time of called routines
+in the running time of the routines that call them.
+The design and use of this profiler is described.
