% "a4" document style option.
% John Pavel, December 1986
% Modified by Graham Gough, May 1987
% Redefines the \textheight and \topmargin for A4 paper, as opposed to US paper.
%% SliTeX test removed for LaTeX2e (DPC)
%
% Adjusting \textheight will adjust position of the bottom of the page.
% Must preserve "(\textheight - \topskip) divides \baselineskip".
% \topskip always appears to be 10pt.
% So only add/subtract multiples of \baselineskip if you want shorter pages.
