     ----PPPP   Generate only the positive masks.

     ----aaaaX  When isolating area around IC is wanted (X/100 micron
	  wide).

     ----hhhh   For printing help.

     ----ooooX  To produce boxes with an overlay of X/100 micron.

     ----vvvv   Verbose, prints processing info about the masks.

     The options can be given all together or separately.

     _P_g_t generates boxes out of the vertical line segments of the
     set "_vln" files.	These are put into the cell directory in
     a set of "_pgt" files, these files are used by the _f_t_a_p_e
     program.  The cell name is the only argument which must be
     specified.  The current working directory must be the pro-
     ject directory.
