+Let the distance in inches from the left edge of the page to
+the vertical line be H, and from the bottom edge to the
+horizontal line be V; let the lengths of the gaps at the top
+and bottom of the vertical line be T and B respectively, and
+the gaps at the left and right of the horizontal line be L
+and R.  For correct alignment of pages, put the following line
+in a file named (for example) margins.ps, and then mention
+margins.ps on the gs command line when printing any of your
+own files:
