! File: amg_dfile_prec_memory_use.f90
!
!
! Subroutine: amg_file_prec_memory_use
! Version: real
!
! This routine prints a memory_useiption of the preconditioner to the standard
! output or to a file. It must be called after the preconditioner has been
! built by amg_precbld.
!
! Arguments:
! p - type(amg_Tprec_type), input.
! The preconditioner data structure to be printed out.
! info - integer, output.
! error code.
! iout - integer, input, optional.
! The id of the file where the preconditioner description
! will be printed. If iout is not present, then the standard
! output is condidered.
! root - integer, input, optional.
! The id of the process printing the message; -1 acts as a wildcard.
! Default is psb_root_
!
!
!
! verbosity:
! <0: suppress all messages
! 0: normal
! >1: increased details
!
