+\big The \TeX\ ruler
+
+\manual
+This is the \TeX\ ruler, a measuring device for
+typographical designers working with \TeX. It includes ordinary
+rulers in inches, centimeters, and picas.
+It can be used to measure font sizes, baseline distances,
+and rule weights. The design is based on a ruler
+by Inge~Eijkhout, implementation in \TeX\ is by
+Victor~Eijkhout.
+
+The \TeX\ ruler is shareware, distributed under the GNU Public License.
+If you want to show your appreciation, send a contribution
+to the address below.
+
+How to format and print this file
+
+This file will give you three pages. Most likely the second one
+cannot be handled by your printer, but I've included it for
+completeness. At the top of the source file, 3 fonts are
+declared. Please change the CM fonts to something more pretty,
+eg Helvetica.
+
+How to use the \TeX\ ruler
+
+Rulers. Use them like ordinary rulers. It is suggested
+that you print the \TeX\ ruler on transparent plastic and
+cut the edges along the rulers.
+
+Baseline distances. Put the top line along the baseline
+of some line of text. Then see in what column the other
+lines of text line up.
+
+Font sizes: cap height. Take an uppercase letter
+such as `K' or `H'. Find the line with its font name,
+or use the first line. See what box on that line
+it fits in best, with the character completely between
+the lines. Read out the magnification and size of the
+font. Alternately check on all lines which box fits
+best, then read out the size.
+
+General remark: all lines have a width of .05 millimeter.
+This is less than the dot width of a 300dpi
+laser printer, so beware of some inaccuracies.
+Also your printer driver may introduce
+inaccuracies.
