% This file is for LaTeX output for A4 paper that may later be
% copied to 8.5 X 11 inch paper.  It maintains the following constraints:
% 1) Top and side margins are at least 25 mm, even after copying.
% 2) The bottom margin (below the page number) is at least 10 mm,
%    even after copying.
% 3) The body has the golden ratio.
% 4) The width should be 2--3 alphabets.
%
% The numbers are derived as follows.  An A4 page is 297 X 210 mm.
% An 8.5 X 11 page is 279 X 216 mm, rounded to the nearest mm.
% Allowing 25 mm for the top margin, 11 mm for the footer, and
% 10 mm for the bottom margin, we can compute the text height
% from the height of the shorter page (the 8.5 X 11) as:
% 279 - 25 - 11 - 10 = 233 mm.  Dividing by the golden ratio
% 0.5 * (1 + sqrt (5)) = 1.6180339887498948482045868343656381177203091798057628
% gives the text width of 145 mm.  This leaves
% (210 - 145) / 2 = 32 mm for the side margins with the narrower
% (A4) paper.
