# % dawncut a b c d input-file [output-file]
#
#       input-file : Source DAWN-format file describing a 3D scene.
#
#       output-file: Output DAWN-format file describing a plane-clipped 
#                    3D scene.  The default output stream is stdout.
#
#       a, b, c, d : Parameters  a, b, c, and d  are double values to
#                    define a clipping plane described with the following 
#                    equation: 
#
#                       ax + by + cz + d = 0. 
#
#                    Vector (a,b,c) defines the normal vector of 
#                    the clipping plane.  
#                    3D scene data in the half space at the front side 
#                    of the clipping plane are clipped out and erased. 
#                    The normal vector (a,b,c) needs not be a unit vector. 
#                    If it is a unit vector, parameter "d" gives distance 
#                    between the clipping plane and origin (0,0,0).
