! Module: amg_prec_type
!
!  This module defines: 
!  - the amg_prec_type data structure containing the preconditioner and related
!    data structures;
!  - integer constants defining the preconditioner;
!  - character constants describing the preconditioner (used by the routines
!    printing out a preconditioner description);
!  - the interfaces to the routines for the management of the preconditioner
!    data structure (see below).
!
!  It contains routines for
!  - converting character constants defining the preconditioner into integer
!    constants; 
!  - checking if the preconditioner is correctly defined;
!  - printing a	description of the preconditioner;
!  - deallocating the preconditioner data structure.
