  abstract =     "A compact package for solving systems of linear
                 equations using multigrid or aggregation-disaggregation
                 methods is described. Imbedded in the algorithms are
                 implementations for sparse Gaussian elimination and
                 symmetric Gauss-Seidel (unaccelerated or accelerated by
                 conjugate gradients or Orthomin(1)). This package is
                 particularly useful for solving problems which arise
                 from discretizing partial differential equations,
                 regardless of whether finite differences, finite
                 elements, or finite volumes are used.",
