% Reference Card for AMSTeX
% Copyright (c) 1994 Joseph H. Silverman. May be freely distributed.
% Created Tuesday, March 29, 1994
% Thanks to Stephen Gildea for the multicolumn macro package
% which I modified from his GNU emacs reference card
% TeX and AMSTeX are trademarks of the American Mathematical Society
%**start of header
\newcount\columnsperpage
% This file can be printed with 1, 2, or 3 columns per page (see below).
% [For 2 or 3 columns, you'll need 6 and 8 point fonts.]
% Specify how many you want here. Nothing else needs to be changed.
\columnsperpage=3
% This file is intended to be processed by plain TeX.
%
% The final reference card has six columns, three on each side.
% This file can be used to produce it in any of three ways:
% 1 column per page
% produces six separate pages, each of which needs to be reduced to 80%.
% This gives the best resolution.
% 2 columns per page
% produces three already-reduced pages.
% You will still need to cut and paste.
% 3 columns per page
% produces two pages which must be printed sideways to make a
% ready-to-use 8.5 x 11 inch reference card.
% For this you need a dvi device driver that can print sideways.
% Which mode to use is controlled by setting \columnsperpage above.
