31 % The final reference card has six columns, three on each side.
|
|
|
32 % This file can be used to produce it in any of three ways:
|
|
|
33 % 1 column per page
|
|
|
34 % produces six separate pages, each of which needs to be reduced to 80%.
|
|
|
35 % This gives the best resolution.
|
|
|
36 % 2 columns per page
|
|
|
37 % produces three already-reduced pages.
|
|
|
38 % You will still need to cut and paste.
|
|
|
39 % 3 columns per page
|
|
|
40 % produces two pages which must be printed sideways to make a
|
|
|
41 % ready-to-use 8.5 x 11 inch reference card.
|
|
|
42 % For this you need a dvi device driver that can print sideways.
|
|
|
43 % Which mode to use is controlled by setting \columnsperpage above.
