But if I recall correctly, SPARSEKIT was one of the "researchy" pkgs I 
alluded to in my previous msg that really only supported one format
internally (compressed sparse row, CSR, if I remember correctly), and 
accomodated other formats by providing routines to convert to and from 
CSR.

Fine for investigating algorithm performance, developing solvers and
preconditioners, etc, but not for "production".
