       _G_e_t_b_b_o_x  reads  each  scene  description _i_n_p_u_t and computes the minimum
       axis-aligned parallelopiped that will enclose all of the objects.  Each
       _i_n_p_u_t  can  be either a file name, or a command (enclosed in quotes and
       preceded by a `!').  If no arguments are given, the standard  input  is
       read.   A hyphen ('-') can also be used to indicate the standard input.

       The _-_w option suppresses warnings.  The _-_h option suppresses the header
       line "xmin xmax ymin ymax zmin zmax".

       To preview ``scene'':

       Since expanding a scene can require considerable overhead, it is better
       to use the bounding cube produced by _o_c_o_n_v_(_1_) and read by _g_e_t_i_n_f_o_(_1_) if
       an  octree  exists  for  the scene.  However, there are certain circum-
       stances, such as foreign object placement,  that  require  knowing  the
       bounding box rather than just the bounding cube.
