!!****  *READ_EXSEG_n * - routine to read  the descriptor file EXSEG
!!
!!    PURPOSE
!!    -------
!       The purpose of this routine is to read the descriptor file called 
!     EXSEG and to control the coherence with FMfile data . 
!       
!!
!!**  METHOD
!!    ------
!!      The descriptor file is read. Namelists (NAMXXXn) which contain
!!    variables linked to one nested model are at the beginning of the file.
!!    Namelists (NAMXXX) which contain variables common to all models
!!    are at the end of the file. When the  model index is different from 1, 
!!    the end of the file (namelists NAMXXX) is not read. 
!!
!!      Coherence between the initial file (description read in DESFM file)
!!    and the segment to perform (description read in EXSEG file)
!!    is checked for segment achievement  configurations 
!!    or  postprocessing configuration. The get indicators are set according 
!!      to the following check :
!!
!!      - segment achievement and preinit configurations :
!!
!!       * if there is no turbulence kinetic energy in  initial
!!      file (HTURB='NONE'), and the segment to perform requires a turbulence
!!      parameterization (CTURB /= 'NONE'), the get indicators for turbulence 
!!      kinetic energy variables are set to 'INIT'; i.e. these variables will be
!!      set equal to  zero by READ_FIELD according to the get indicators.
!!       * The same procedure is applied to the dissipation of TKE. 
!!       * if there is no moist variables RRn  in  initial file (OUSERn=.FALSE.)
!!      and the segment to perform requires  moist variables RRn
!!      (LUSERn=.TRUE.),  the get indicators for moist variables RRn are set
!!      equal to 'INIT'; i.e. these variables will be set equal to  zero by 
!!      READ_FIELD according to the get indicators.
!!       * if there are KSV_USER additional scalar variables in initial file and the
!!      segment to perform needs more than KSV_USER additional variables,  the get
!!      indicators for these (NSV_USER-KSV_USER) additional scalar variables are set 
!!      equal to 'INIT'; i.e. these variables will be set equal to  zero by 
!!      READ_FIELD according to the get indicators. If the segment to perform
!!      needs less additional scalar variables than there are in initial file,
!!      the get indicators for these (KSV_USER - NSV_USER) additional scalar variables are
!!      set equal to 'SKIP'.      
!!       * warning messages are printed if the fields in initial file are the
!!      same at time t and t-dt (HCONF='START') and  a leap-frog advance 
!!      at first time step will be used  for the segment to perform
!!      (CCONF='RESTA'); It is likewise when HCONF='RESTA' and CCONF='START'.
!!       * A warning message is printed if the orography in initial file is zero
!!      (OFLAT=.TRUE.) and the segment to perform considers no-zero orography
!!      (LFLAT=.FALSE.). It is likewise for LFLAT=.TRUE. and OFLAT=.FALSE..
!!       If the segment to perform requires zero orography (LFLAT=.TRUE.), the
!!       orography (XZS) will not read in initial file but  set equal to zero 
!!       by SET_GRID.  
!!       * check of the depths of the Lateral Damping Layer in x and y 
!!       direction is performed
!!       * If some coupling files are specified, LSTEADYLS is set to T
!!       * If no coupling files are specified, LSTEADYLS is set to F
