%%% Margins for centering the text on the page
% A4 paper width is 21cm, hence total margin is 21cm - 15.92cm = 5.08cm
% leftmargin is 5.08cm/2 = 2.54cm, subtracting the 1in = 2.54cm offset,
% we get 0cm for \oddsidemargin
\setlength{\oddsidemargin}{0 cm}
\setlength{\evensidemargin}{0 cm}
% For Letter paper, width is 11in = 21.59cm, hence
% the \oddsidemargin should be set to 1.36 + .295 = 1.655cm

% Vertically: (1pt = 0.351mm)
% A4 paper height is 29.7cm = 845pt,
% total printed page height is 22.26cm (= 634pt) + \headsep + \headheight + \footskip
% with \headsep = 25pt, \headheight = 12pt, and \footskip = 30pt
% hence total margin is 845pt (= 29.7cm) - 634pt - 67pt = 144pt
% Topmargin is 144pt/2 = 72pt = 2.54cm, subtracting the 1in = 2.54cm offset,
