! Module: psb_prec_mod
!
!  This version of the preconditioner module psb_prec_mod renames "on the fly"
!  the MLD2P4 preconditioner routines and data types so that the Krylov solvers
!  in PSBLAS can be tricked into using the MLD2P4 versions instead of the original
!  ones. Since there is no native runtime polymorphism this implies a recompilation,
!  but thanks to the renaming feature of Fortran 95 (and to the compatibility of
!  the calling sequences) there is no need to change the source code for the
!  Krylov methods.
