+function varargout = processgrid_mex(varargin)
+%Compute grid topology and geometry from pillar grid description.
+%
+% SYNOPSIS:
+%   G = processGRDECL(grdecl)
+%
+% PARAMETERS:
+%   grdecl - Raw pillar grid structure, as defined by function
+%            'readGRDECL', with fields COORDS, ZCORN and, possibly, ACTNUM.
+%
+% RETURNS:
+%   G      - Valid grid definition containing connectivity, cell
+%            geometry, face geometry and unique nodes.
+%
+% EXAMPLE:
+%   G = processgrid(readGRDECL('small.grdecl'));
+%   plotGrid(G); view(10,45);
+%
+% SEE ALSO:
+%   processGRDECL, readGRDECL, deactivateZeroPoro, removeCells.
