+% Reference Card for GNU Emacs Calc 2.02
+%**start of header
+\newcount\columnsperpage
+
+% The format for this file is adapted from the GNU Emacs reference
+% card version 1.9, by Stephen Gildea.
+
+% This file can be printed with 1, 2, or 3 columns per page (see below).
+% Specify how many you want here.  Nothing else needs to be changed.
+
+\columnsperpage=3
+
+% Typical command to format:  tex calccard.tex
+% Typical command to print (3 cols):  dvips -t landscape calccard.dvi

+% This file is intended to be processed by plain TeX (TeX82).
+%
+% 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.
