1 % Reference Card for GNU Emacs Calc 2.02
2 %**start of header
3 \newcount\columnsperpage
5 % The format for this file is adapted from the GNU Emacs reference
6 % card version 1.9, by Stephen Gildea.
8 % This file can be printed with 1, 2, or 3 columns per page (see below).
9 % Specify how many you want here.
11 \columnsperpage=3
13 % PDF output layout. 0 for A4, 1 for letter (US), a `l' is added for
14 % a landscape layout.
16 \input pdflayout.sty
17 \pdflayout=(1l)
19 % Nothing else needs to be changed.
20 % Typical command to format: tex calccard.tex
21 % Typical command to print (3 cols): dvips -t landscape calccard.dvi

40 % This file is intended to be processed by plain TeX (TeX82).
42 % The final reference card has six columns, three on each side.
43 % This file can be used to produce it in any of three ways:
44 % 1 column per page
45 % produces six separate pages, each of which needs to be reduced to 80%.
46 % This gives the best resolution.
47 % 2 columns per page
48 % produces three already-reduced pages.
49 % You will still need to cut and paste.
50 % 3 columns per page
51 % produces two pages which must be printed sideways to make a
52 % ready-to-use 8.5 x 11 inch reference card.
53 % For this you need a dvi device driver that can print sideways.
54 % Which mode to use is controlled by setting \columnsperpage above.
