  Description     : iterative solvers for general sparse linear systems of equations

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
