#	There are four packages in the ITPACK directory for solving
#	large sparse linear systems by iterative methods:  ITPACK 2C (single
#	precision), ITPACK 2C (double precision), ITPACKV 2D (a vectorized
#	version of ITPACK 2C for the Cray Y-MP and similar vector computers),
#	and NSPCG.  ITPACK 2C and ITPACKV 2D are intended for symmetric and
#	positive-definite matrix problems.  NSPCG has preconditioners and
#	polynomial accelerators for nonsymmetric matrix problems as well.
#	Only single precision versions are available for ITPACKV 2D
#	and NSPCG.  Machine-dependent constants and the timing function may
#	need to be modified by the user when installing the packages for a
#	particular computer.  They are located in routines DFAULT and TIMER in
#	all four packages.
