DESCRIPTION     : string (256 characters max) which describes 
                  the resulting grid and mappings
GRID_IN         : name of the file with grid in 
                  GRIDMAN_GRID format
CONTOUR_IN          : name of the input file with cloused contour 
                      (in template format) which is used to cut the grid 

UNIT2METER          : if UNIT2METER>0., then this is a 
                      factor which translates the units of CONTOUR_IN 
                      into Meter. E.g. if coordinates in CONTOUR_IN 
                      are defined in Centimeter then UNIT2METER=1e-2     
                      If UNIT2METER<=0., then the transformation
                      is not applied, it is assumed that the coordinates
                      in CONTOUR_IN are defined in Millimeter.
                      Default UNIT2METER=-1.,

LEXCLUDE        : if .FALSE. then part of the grid inside  
                  CONTOUR_IN is taken to the resulting grid,
                  if .TRUE. then CONTOUR_IN is excluded from 
                  the resulting grid. Default value .FALSE. 

IEIND : if IEIND>0 then edge index number IEIND of GRID_IN is
        merged into indexes of segments in CONTOUR_IN and 
        is stored as first edge index of GRID_OUT

GRID_OUT            : name of the file where the resulting grid is stored 

DBGMOD  : if .TRUE. then extra debugging output is produced.
          Default is .FALSE.
LCHECK  : if .TRUE. then standard check in GRIDMAN subroutines 
          are enforced.  Default is .FALSE.
TOL     : tolerance parameters, default is GRIDMAN_TOL 

CUTGRID may not handle properly the situation when the polygon 
(contour) segments intersect the grid nodes, or when the grid 
edges intersect the polygon vertices. To identify such intersections 
it is recommended to run the program with LCHECK=.TRUE.
