+Notes on the Computer Modern parameters
+
+Dimensions are mostly in units of 1/36pt, because I originally worked
+on graph paper with 36 pixels per point (in 1977). This experience made
+me familiar with such units, so I later decided to make METAFONT produce
+proofmode output at the same scale.
+
+The basic fonts cmr5--cmr17 scale proportionately in most vertical
+dimensions (e.g., the x_height in 5pt is half that in 10pt), but
+horizontally the smaller fonts are more extended and have relatively
+heavier weight (especially in hairlines).
+
+The slanted fonts cmsl8--cmsl12 are identical to their unslanted
+counterparts except that they have slant=1/6.
+
+Font cmdunh10 is the same as cmr10 except that body_height, asc_height,
+cap_height, and fig_height have been drastically increased.
+
+The bold fonts cmbx5--cmbx12 have similar vertical dimensions to the ordinary
+roman (except that the x_height is a bit taller and bar_height is lower);
+they use bolder pen strokes, of course, and they are rather more extended.
+Font cmb10 is like cmbx10 except not extended (i.e., 1em=10pt in cmb10,
+but 1em=11.5pt in cmbx10); it also has slightly shorter cap serifs. Font
+cmbxsl10 is like cmbx10 but slanted.
+
+The typewriter fonts cmtt8--cmtt12 have the same x_heights as their
+roman counterparts, but they have shorter ascenders and longer descenders.
+Their math_axis is based on ascenders only. The stroke weights are
+almost all identical to the corresponding roman stem weight.
+Font cmsltt10 is a slanted version of cmtt10; cmvtt10 is non-monospaced.
+
+The sans serif fonts cmss8--cmss17 are analogous to cmr8--cmr17; they have
+slanted counterparts with slant of 12 degrees. A few other isolated sans
+serif fonts appear in the standard set, as demonstrations of how other
+varieties could be made: There's a demibold condensed version, cmssdc10,
+and a bold extended version, cmssbx10. (The title pages in The TeXbook use
+cmssdc10 at 40pt and a magnified version of cmssbx10 called cminch; to
+save font storage space, cminch is restricted to digits and uppercase
+letters only.) Finally, there's a pair of fonts called cmssq8 and cmssqi8;
+these are in a rather different style (extended, with short ascenders
+and descenders), used for the end-of-chapter quotations in The TeXbook.
+
+The font cmfib8 is another `demonstration' of parameters; it's a serifed
+font whose proportions are based on Fibonacci numbers. Also, the font
+cmff10 is a weird concoction of little use except for testing.
+
+The text italic fonts cmti7--cmti12 have parameters like their roman
+cousins, except that they are more condensed and slightly lighter.
+The math italic fonts cmmi5--cmmi12 are not condensed and not
+quite as light.
+
+Four special italic fonts are provided as demonstrations of further
+possibilities: cmbxti10 is a bold extended text italic; cmmib10 is
+a bold math italic; cmit10 is an italic typewriter font; cmu10 is
+an unslanted italic with the same stem weights as cmr10.
+
+The math symbol fonts, cmsy5--cmsy10, have the same parameters
+as the corresponding math italic; these fonts also have special
+parameters of their own. There's a bold math symbols font for
+demonstration purposes: cmbsy10.
+
+The math extension font, cmex10, has the parameters of cmr10.
+
+The extended ASCII font, cmtex10, has the parameters of cmtt10, except
+that the slant is positive (for a few characters that will be slanted).
+
+And finally there are two caps-and-small-caps fonts, cmcsc10 (to match cmr10)
+and cmtcsc10 (to match cmtt10). These fonts are unusual in having two
+sets of parameters, one for the upper uppercase and one for the lower uppercase.

+% THIS IS THE OFFICIAL COMPUTER MODERN SOURCE FILE accent.mf BY D E KNUTH.
+% IT MUST NOT BE MODIFIED IN ANY WAY UNLESS THE FILE NAME IS CHANGED!
+
+% This file contains accents common to text roman and italic fonts.
+% Character codes \0022--\0030, \0040, \0136--\0137, \0175--\0177 are generated.
+
+% (Actually the accents in positions \0040, \0137, and \0175 are not generated
+% unless |ligs>0|, since other symbols are substituted
+% for those accents in non-ligature fonts.)

+% THIS IS THE OFFICIAL COMPUTER MODERN SOURCE FILE bigdel.mf BY D E KNUTH.

+
+% This file contains series of large delimiters for math extension fonts.
+
+% The sizes are `{\tt\char`\\big}' (|2dh#|), `{\tt\char`\\Big}' (|3dh#|),
+% `{\tt\char`\\bigg}' (|4dh#|), and `{\tt\char`\\Bigg}' (|5dh#|),
+% followed in most cases by an extensible character that can grow
+% arbitrarily large in |dh#| steps,
+% where |dh#| is 60\% of the font design size.
+% (For example, a 10-point font will have large delimiters in sizes
+% 12$\,$pt, 18$\,$pt, 24$\,$pt, 30$\,$pt, 36$\,$pt, 42$\,$pt, etc.)
+
+% Character codes \0000--\0105 and \0150--\0177 are generated.

+% THIS IS THE OFFICIAL COMPUTER MODERN SOURCE FILE bigop.mf BY D E KNUTH.
+% IT MUST NOT BE MODIFIED IN ANY WAY UNLESS THE FILE NAME IS CHANGED!
+
+% This file contains pairs of large operators for math extension fonts.
+
+% Each operator has a `{\tt\char`\\textstyle}' form, for math in text,
+% and a `{\tt\char`\\displaystyle}' form, for displayed formulas.
+
+% Character codes \0106--\0141 are generated.

+% THIS IS THE OFFICIAL COMPUTER MODERN SOURCE FILE greekl.mf BY D E KNUTH.
+% IT MUST NOT BE MODIFIED IN ANY WAY UNLESS THE FILE NAME IS CHANGED!
+
+% This lowercase Greek alphabet was prepared by D. E. Knuth in December, 1979,
+% inspired by the Monotype faces used in {\sl The Art of Computer Programming}.
+% (It has been designed for math formulas, not Greek texts.)
+% The programs were revised for the new \MF\ conventions in 1985.
+
+% Character codes \0013--\0047 are generated.

+% THIS IS THE OFFICIAL COMPUTER MODERN SOURCE FILE itall.mf BY D E KNUTH.
+% IT MUST NOT BE MODIFIED IN ANY WAY UNLESS THE FILE NAME IS CHANGED!
+
+% Computer Modern Italic lower case:
+% This lowercase italic alphabet was prepared by D. E. Knuth in December, 1979,
+% inspired by the Monotype faces used in {\sl The Art of Computer Programming}.
+% The programs were revised for the new \MF\ conventions in 1985.
+
+% Character codes \0141 through \0172 are generated.

+% THIS IS THE OFFICIAL COMPUTER MODERN SOURCE FILE romanl.mf BY D E KNUTH.
+% IT MUST NOT BE MODIFIED IN ANY WAY UNLESS THE FILE NAME IS CHANGED!
+
+% Computer Modern Roman lower case:
+% These letters were originally coded by D. E. Knuth in November, 1979,
+% inspired by the Monotype faces used in {\sl The Art of Computer Programming}.
+% Sans serif designs by Richard Southall were added in April, 1982.
+% The programs were revised for the new \MF\ conventions in 1985.
+
+% Character codes \0141 through \0172 are generated.

+% THIS IS THE OFFICIAL COMPUTER MODERN SOURCE FILE romanu.mf BY D E KNUTH.
+% IT MUST NOT BE MODIFIED IN ANY WAY UNLESS THE FILE NAME IS CHANGED!
+
+% Computer Modern Roman upper case:
+% These letters were originally coded by D. E. Knuth in November, 1979,
+% inspired by the Monotype faces used in {\sl The Art of Computer Programming}.
+% Sans serif designs by Richard Southall were added in April, 1982.
+% The programs were revised for the new \MF\ conventions in 1985.
+
+% Character codes \0101 through \0132 are generated.

+% THIS IS THE OFFICIAL COMPUTER MODERN SOURCE FILE symbol.mf BY D E KNUTH.
+% IT MUST NOT BE MODIFIED IN ANY WAY UNLESS THE FILE NAME IS CHANGED!
+
+% This file defines the symbols of a \TeX\ math symbol font.
+% Character codes \0000--\0100 and \0133--\0177 are generated.

+% (Improvements to the author's original characters were worked out in 1982
+% by Ronald F. Whitney and other members of

+
+% Italic corrections have not been computed for most of these characters,

+% Special slanted characters for ``extended ASCII character set'' fonts
+
+% These characters were copied from {\tt greekl.mf} and {\tt italms.mf}
+% with character positions changed and italic corrections added to the width.
