;
; @param filename {in}{optional}{default='meshmask.nc'}{type=scalar string}
; Name of the meshmask file to read. If this name does not contain any "/"
; and if iodirectory keyword is not specified, then the common variable
; iodir will be used to define the mesh file path.
;
; @keyword GLAMBOUNDARY {default=those defined in the file}{type=2 elements vector}
; Longitude boundaries that should be used to visualize the data.
; lon2 > lon1
; lon2 - lon1 le 360
; By default, the common (cm_4mesh) variable key_shift will be automatically
; defined according to GLAMBOUNDARY.
;
; @keyword CHECKDAT
; Suppressed. Use micromeshmask to create an appropriate meshmask.
;
; @keyword ONEARTH {default=1}{type=scalar: 0 or 1}
; Force the manual definition of data localization on the earth or not
; 0) if the data are not on the earth
; 1) if the data are on earth (in that case we can for example use
; the labels 'longitude', 'latitude' in plots).
; The resulting value will be stored in the common (cm_4mesh) variable key_onearth
; ONEARTH=0 forces PERIODIC=0, SHIFT=0 and is cancelling GLAMBOUNDARY
;
; @keyword GETDIMENSIONS {default=0}{type=scalar: 0 or 1}
; Activate this keywords if you only want to know the dimension
; of the domain stored in the mesh file. This dimension will be
; defined in jpiglo, jpjglo, jpkglo (cm_4mesh common variables)
;
; @keyword PERIODIC {default=computed by using the first line of glamt}{type=scalar: 0 or 1}
; Force the manual definition of the grid zonal periodicity.
; The resulting value will be stored in the common (cm_4mesh) variable key_periodic
; PERIODIC=0 forces SHIFT=0
;
; @keyword SHIFT {default=computed according to glamboundary}{type=scalar}
; Force the manual definition of the zonal shift that must be apply to the data.
; The resulting value will be stored in the common (cm_4mesh) variable key_shift
; Note that if key_periodic=0 then in any case key_shift = 0.
;
; @keyword STRCALLING {type=scalar string}
; the calling command used to call computegrid (this is used by xxx)
;
; @keyword STRIDE {default=[1, 1, 1]}{type=3 elements vector}
; Specify the stride in x, y and z direction. The resulting
; value will be stored in the common (cm_4mesh) variable key_stride
;
; @keyword _EXTRA
; Used to pass keywords to isafile
;
; @uses
; cm_4mesh
; cm_4data
; cm_4cal
;
; @restrictions
; ixminmesh, ixmaxmesh, iyminmesh, iymaxmesh, izminmesh, izmaxmesh must
; be defined before calling ncdf_meshread. If some of those values
; are equal to -1 they will be automatically defined

; Sebastien Masson (smasson\@lodyc.jussieu.fr)
; 12/1999
; July 2004, Sebastien Masson: Several modifications (micromeshmask,
; clean partial steps, clean use of key_stride, automatic definition
; of key_shift, ...)
; Oct. 2004, Sebastien Masson: add PERIODIC and SHIFT
; Aug. 2005, Sebastien Masson: some cleaning + english
