-% File LFONTS - Version of 21 November 1989,
-% plus modifications for PostScript Times family fonts (added by Larry
-% Denenberg, larry@bbn.com, originally 5 Apr 88 and later 13 Feb 91).
-% PS font names changed to use Karl Berry's names like dvips does,
-% Stephen Gildea, Sep 92.
-
-% This version of LFONTS.TEX is for the CMR fonts. It was converted
-% from the AMR version by David Fuchs on 18 December 1985.
-% And corrected on 11 Nov 1986 by Leslie Lamport.
-% Last vestige of AMR fonts removed 3 Mar 89 by Leslie Lamport.
-
-% This file needs to be customized for the fonts available at a particular
-% site. There are three places where changes need to be made. They
-% can be found by searching this file for the string FONT-CUSTOMIZING.
-%
-% FONT CONVENTIONS
-%
-% A TYPESTYLE COMMAND is something like \it that defines a type style.
-% Each style command \xx is defined to be \protect\pxx, where
-% \pxx is defined to choose the correct font for the current size.
-% This allows style commands to appear in 'unsafe' arguments where
-% protection is required.
-%
-% A SIZE COMMAND is something like \normalsize that defines a type size.
-% It is defined by the document style. However, \normalsize is handled
-% somewhat differently because it is called so often--e.g., on every
-% page by the output routine. The document style defines \@normalsize
-% instead of \normalsize.
-%
-% A ONE-SIZE typestyle is one that exists only in the \normalsize size.
-%
-% A FONT-SIZE COMMAND is one that defines \textfont, \scriptfont and
-% \scriptscriptfont for the font families corresponding to preloaded fonts,
-% as well as the typestyle commands for the preloaded fonts. Each
-% font-size command has an associated @fontsize command, having the same
-% name except for an '@' at the front. All font-size commands are defined
-% in LFONTS. The naming convention is that a fifteenpt font has a font-size
-% name \xvpt, and so on.
-%
-% Each size command \SIZE executes the command
-% \@setsize\SIZE{BASELINESKIP}\FONTSIZE\@FONTSIZE
-% which does the following.
-% 0. Executes \@nomath\SIZE to issue warning if in math mode.
-% 1. \let \@currsize = \SIZE
-% 2. Sets \strutbox to a strut of height .7 * BASELINESKIP and
-% depth .3 * BASELINESKIP
-%
-% Note: Charles Karney observed that step 2 is useless, since the
-% \FONTSIZE command executed in step 4 resets \strutbox using
-% the actual baselineskip, which is \baselinestretch * BASELINESKIP.
-% Some day, this step may get removed. (Note made 28 Feb 89)
-%
-% 3. Sets \baselineskip to \baselinestretch * BASELINESKIP
-% and
-% 4. Calls \FONTSIZE
-% 5. Executes the \@FONTSIZE command.
-% It should then define all the typestyle commands not defined by the font-size
-% command, except for the one-size type styles. A typestyle command for which
-% the corresponding font exists but is not preloaded is defined to expand to a
-% \@getfont command. A typestyle whose font does not exist is defined to
-% expand to a \@subfont command.
-%
-% A one-size typestyle whose font is not preloaded is defined to expand to
-% a \@onesizefont command.
-%
-% \em is defined to be \it inside an unslanted style and \rm inside a
-% slanted style. An \em command in a section title will produce a \pem
-% command in the table of contents.

-% \@getfont \STYLE \FAM \@FONTSIZE{LOADING.INFO}
-% \STYLE = style command
-% \FAM = a control sequence defined by \newfam\FAM
-% \@FONTSIZE = the @fontsize command for the current size.
-% LOADING.INFO = information needed to load the font--e.g.,
-% cmtti10 \magstep 2
-% Does the following, where \FONTNAME denotes a new unique, untypeable
-% font name:
-% 1. Executes \font \FONTNAME = LOADING.INFO
-% 2. Appends '\textfont FAM \FONTNAME \def\STYLE{\fam \FAM \FONTNAME}'
-% to the definition of \@FONTSIZE.
-% 3. Executes \@FONTSIZE \STYLE.
-%
-% \@nohyphens\STYLE\@FONTSIZE
-% Used right after \@getfont to set \hyphenchar of the new font to -1,
-% thereby prohibiting hyphenation. It is used with \tt fonts.
-% (\@nohyphens was added on 12/18/85)
-%
-% \@subfont \STYLE \REPSTYLE
-% \STYLE, \REPSTYLE = type style commands.
-% Types warning message and defines uses \REPSTYLE.
-%
-% \@onesizefont \STYLE {LOADING.INFO}
-% Defines \STYLE to be a typestyle that exists only for the \normalsize
-% size. It produces the font specified by LOADING.INFO

-%% FONT-CUSTOMIZING: The commands \vpt, \vipt, ... , \xxvpt perform all
-%% the declarations needed to change the type size to 5pt, 6pt, ... ,
-%% 25pt. To see how this works, consider the definition of \viipt,
-%% which determines the fonts used in a 7pt type size. The command
-%% \def\pit{\fam\itfam\sevit}
-%% means that the \it command causes the preloaded \sevit font to
-%% be used--this font was defined earlier with a \font\sevit...
-%% command. The commands
-%% \textfont\itfam\sevit
-%% \scriptfont\itfam\sevit
-%% \scriptscriptfont\itfam\sevit
-%% tell TeX to use the \sevit font for all three math-mode sizes
-%% (text, script, and scriptscript) for the 7pt size.
-%% The fonts appearing in these commands must be preloaded.
-%%
-%% The command
-%% \def\pbf{\@getfont\pbf\bffam\@viipt{ambx7}}
-%% declares \bf to use a loaded-on-demand font--namely, the font
-%% ambx7.
-%%
-%% The command
-%% \def\ptt{\@subfont\tt\rm}
-%% declares that the \tt font is unavailable in the 7pt size, so
-%% the \rm font is used instead. (The substituted type style should
-%% correspond to a preloaded size.)
