% This version of lfonts.tex has true-size fonts in place of scaled 
% ten-point fonts.  For further information on how to make this
% improvement to LaTeX, see the directory ../TeXcontrib/sauter
% especially the README.unix file.
%
% File LFONTS - Version of 6 May 1986.
%
% This version of LFONTS.TEX is for the CMR fonts.  It was converted
% from the AMR version by David Fuchs on 18 December 1985.
%
% 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
%   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
%
% \@addfontinfo\@FONTSIZE{DEFS}
%    Expands DEFS and adds to the definition of \@FONTSIZE. Items that should 
%    not be expanded should be protected with \@prtct---except no protection
%    is needed for '\def\foo', only for the contents of the definition.

%    in math mode.

%% 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.)
