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.
