%
%    Here is the main problem. I want to allow users to print out this
%    document on US letter-size paper (8.5x11 inches) or on A4 paper
%    (210x297 mm). And in order to fit maximum text on minimum paper
%    (save the trees) I want to print with small margins and
%    two-column layout (or even three-column, in the case of landscape
%    printing, if that were feasible; but I don't want to assume that
%    the user has Frank's multicol package). But the verbatim examples
%    in the document consist in many cases of lines from TeX screen
%    output, which can be up to 79 characters in length. It is
%    difficult to give two columns wide enough to accommodate
%    80-character lines printed in cmtt unless the size is cut down
%    very small. Then we encounter the difficulty that the
%    lowest-common-denominator set of TeX fonts includes cmtt10,
%    cmtt9, cmtt8, but not cmtt7 or any smaller sizes of cmtt. Well,
%    perhaps that's just as well since things start to get a little
%    hard to read anyway once you get down that small.
%
%    But anyway there it is: How to fit two columns of text, each of
%    minimum width approximately 80 cmtt characters, into the
%    rectangles provided by US letter paper and A4 paper, while trying
%    to keep a decent line length for readability in the neighborhood
%    of two or three alphabets.
%
%    It seems that one part of the answer is to print the 80-character
%    verbatim lines in a smaller point size than the main text.

% 8.5in = 614.295pt.
% 11in = 794.96999pt.
% 210mm = 597.50787pt.
% 297mm = 845.04684pt.

% 80 characters, cmtt10: 419.99634pt.
% 80 characters, cmtt8: 340.00488pt.
% 76 characters, cmtt8: 323.00464pt.
% 70 characters, cmtt8: 297.50427pt.

%    Assume that minimum margins all around are 22pt, approx 8mm /
%    0.3in. And that desired gutter margin between columns is 6pt.
%    Then subtract 50pt from paper width and divide by 2 to get
%    available column width: 210mm 274pt, 8.5in 282pt, 11in 372pt,
%    297mm 397pt.
%
%    Standard \headheight, \headsep are 12pt, 25pt. So next we look for
%    minimum bounding rectangle for landscape, two-column printing:
%    textheight limited by A4 short dimension = 210mm = 598pt.
%    Subtract 44pt for margins, then another 37pt for running head,
%    that leaves textheight of 517pt.
%
%    Similarly for textwidth: Limited by the 11in long dimension of US
%    letter size paper; subtract 50pt for margins and gutter, that
%    leaves 745pt, or 372pt per column.
