! Subroutine: psb_cdprt
!    Prints the descriptor to an output file
! 
! Arguments: 
!    iout          - integer.                The output unit to print to.
!    desc_p        - type(psb_desc_type).  The communication descriptor to be printed.
!    glob          - logical(otpional).      Wheter to print out global or local data.
!    short         - logical(optional).      Used to choose a verbose output.
