% File LFONTS - Version of 21 November 1989,
2
% plus modifications for PostScript Times family fonts (added by Larry
3
% Denenberg, larry@bbn.com, originally 5 Apr 88 and later 13 Feb 91).
4
% PS font names changed to use Karl Berry's names like dvips does,
5
% Stephen Gildea, Sep 92.
7
% This version of LFONTS.TEX is for the CMR fonts. It was converted
8
% from the AMR version by David Fuchs on 18 December 1985.
9
% And corrected on 11 Nov 1986 by Leslie Lamport.
10
% Last vestige of AMR fonts removed 3 Mar 89 by Leslie Lamport.
12
% This file needs to be customized for the fonts available at a particular
13
% site. There are three places where changes need to be made. They
14
% can be found by searching this file for the string FONT-CUSTOMIZING.
18
% A TYPESTYLE COMMAND is something like \it that defines a type style.
19
% Each style command \xx is defined to be \protect\pxx, where
20
% \pxx is defined to choose the correct font for the current size.
21
% This allows style commands to appear in 'unsafe' arguments where
22
% protection is required.
24
% A SIZE COMMAND is something like \normalsize that defines a type size.
25
% It is defined by the document style. However, \normalsize is handled
26
% somewhat differently because it is called so often--e.g., on every
27
% page by the output routine. The document style defines \@normalsize
28
% instead of \normalsize.
30
% A ONE-SIZE typestyle is one that exists only in the \normalsize size.
32
% A FONT-SIZE COMMAND is one that defines \textfont, \scriptfont and
33
% \scriptscriptfont for the font families corresponding to preloaded fonts,
34
% as well as the typestyle commands for the preloaded fonts. Each
35
% font-size command has an associated @fontsize command, having the same
36
% name except for an '@' at the front. All font-size commands are defined
37
% in LFONTS. The naming convention is that a fifteenpt font has a font-size
38
% name \xvpt, and so on.
40
% Each size command \SIZE executes the command
41
% \@setsize\SIZE{BASELINESKIP}\FONTSIZE\@FONTSIZE
42
% which does the following.
43
% 0. Executes \@nomath\SIZE to issue warning if in math mode.
44
% 1. \let \@currsize = \SIZE
45
% 2. Sets \strutbox to a strut of height .7 * BASELINESKIP and
46
% depth .3 * BASELINESKIP
48
% Note: Charles Karney observed that step 2 is useless, since the
49
% \FONTSIZE command executed in step 4 resets \strutbox using
50
% the actual baselineskip, which is \baselinestretch * BASELINESKIP.
51
% Some day, this step may get removed. (Note made 28 Feb 89)
53
% 3. Sets \baselineskip to \baselinestretch * BASELINESKIP
56
% 5. Executes the \@FONTSIZE command.
57
% It should then define all the typestyle commands not defined by the font-size
58
% command, except for the one-size type styles. A typestyle command for which
59
% the corresponding font exists but is not preloaded is defined to expand to a
60
% \@getfont command. A typestyle whose font does not exist is defined to
61
% expand to a \@subfont command.
63
% A one-size typestyle whose font is not preloaded is defined to expand to
64
% a \@onesizefont command.
66
% \em is defined to be \it inside an unslanted style and \rm inside a
67
% slanted style. An \em command in a section title will produce a \pem
68
% command in the table of contents.
