description         ITerative SOLvers for sparse linear systems.

long_description    ITSOL is a library of iterative solvers for general sparse linear systems of equations. \
                    ITSOL can be viewed as an extension of the itsol module in SPARSKIT. It is written in C \
                    and offers a selection of recently developed preconditioners. The preconditioner suite includes: \
                    ILUK (ILU preconditioner with level of fill),  \
                    ILUT (ILU preconditioner with threshold), \
                    ILUC (Crout version of ILUT), \
                    VBILUK (variable block preconditioner with level of fill - with automatic block detection), \
                    VBILUT (variable block preconditioner with threshold - with automatic block detection), \
                    ARMS (Algebraic Recursive Multilevel Solvers -- includes actually several methods, \
                    in particular the standard ARMS and the ddPQ version which uses nonsymmetric permutations). \
                    Note that ITSOL is a scalar package.
