     ----ccccL     select check level 'L' (positive integer value).
	     The check level specifies the level of the lowest
	     cells in the cell hierarchy which are expanded.
	     These are separate cell expansions, which contains
	     all overlaps of the underlaying cell levels
	     (default: only the cell on top of the hierarchy is
	     expanded (minimum level = 1)).

     ----ooooN     set the size of the active region to 'N' (default: 6
	     micron).

     ----vvvv      verbose mode.

     ----wwwwXl,Xr,Yb,Yt
	     select a partial expansion window.  The window coor-
	     dinates (integer values) must be specified as one
	     argument (no blanks are allowed).	Xl,Xr,Yb,Yt are
	     respectively the left and right X-coordinates, and
	     bottom and top Y-coordinates (default: the expansion
	     window is the cell bounding box).

     _M_a_k_e_b_o_x_h takes the internal database description of the cell
     and converts it to boxes.

     _M_a_k_e_b_o_x_h expands the cell _h_i_e_r_a_r_c_h_i_c_a_l_l_y, i.e. the cell and
     all lower cells are expanded based on the assumption that
     the lower cells are already verified.  If an expansion win-
     dow is specified, only the boxes in that window are
     expanded.

     The cell argument is the cell name and must be the last
     argument.	The current working directory must be the project
     directory.  _M_a_k_e_b_o_x_h creates a special file "exp_dat", which
     contains the names of the cells which are expanded.
