C     This file summarizes the DOUBLE PRECISION routines
C     in this directory. SINGLE PRECISION names are obtained
C     by replacing the leading D with S in all names.
C
C     DTEST1   Simple test driver for DCUTET.
C     DTEST2   More detailed test driver for DCUTET.
C              Sample output from a SUN 3/50 is included.
C     DCUTET   Main Integrator.DCUTET calls DCHTET and DADTET.
C     DCHTET   Checks the input to DCUTET.
C     DADTET   The adaptive integration routine. 
C              DADTET calls DTRTET and DRLTET.
C     DTRTET   Maintaines the heap of subtetrahedronds.
C     DRLTET   Computes estimates of integral and error over
C              subtetrahedrons.
C     DORTET   Computes fully symmetric sums of function evaluations.
