% FONTS
%
% Supply default names for the fonts because my own font definitions
% store their own names in these macros, and if you're processing
% this yourself (ie without my fonts) I still want the references to
% font names in the session on fonts to work. These are defaults.
%
\newcommand{\rmfontfamilyname}{Computer Modern Roman}
\newcommand{\sffontfamilyname}{Computer Modern Sans-Serif}
\newcommand{\ttfontfamilyname}{Computer Modern Typewriter}
%
% I invoke pslatex before my private fonts so I get the benefit of the
% narrowed Courier, which is useful. If anyone knows the location of a
% free Prestige Elite (Type 1) font, which was a freebie give-away on
% some DTP CD-ROM in the late 1990s, of which I have lost my copy, I
% would be very grateful to know.
%
% ald721 and hum521 are Bitstream's Aldine (Bembo) and Humanist (Gill)
%\usepackage{pslatex,ald721,hum521}
% carmina and inc901 are also Bitstream for Carmina and Antique Olive
%\usepackage{pslatex,carmina,inc901}
% The pslatex default is narrowed Courier, so say so:
\renewcommand{\ttfontfamilyname}{Courier Narrow}
% These redefinitions seem to be needed (is ly1enc.def faulty?)
% Comment them out if you're not using LY1 (my Bitstream fonts need them)
%\renewcommand{\ae}{\char'032}
%\renewcommand{\AE}{\char'035}
%\renewcommand{\o}{\char'034}
%\renewcommand{\O}{\char'037}
% As you won't have any of them, comment out those lines and UNcomment
% the following FOUR lines to get Times and Helvetica (\snore):
%\renewcommand{\rmfontfamilyname}{Times}
%\renewcommand{\sffontfamilyname}{Helvetica}
%\renewcommand{\ttfontfamilyname}{Courier}
%\usepackage{pslatex}
% Alternatively you could UNcomment these four lines instead:
\renewcommand{\rmfontfamilyname}{Palatino}
\renewcommand{\sffontfamilyname}{Avant Garde}
\renewcommand{\ttfontfamilyname}{Courier}
\usepackage{pslatex,palatino,avant}
%
% And yes, I do know that pslatex is obsolete and deprecated, and when
% someone gets around to updating it to do things the way they say
% they ought to be, I'll get around to updating this style file.
%
% Anyway, in this case (for TUGboat), I fiddled with the .fd file for
% Avant Garde and decreased the size to 90% because it's a font with
% a very large x-height and it needs to be smaller to sort with
% Palatino. Ditto with the special narrow Courier in pslatex.sty: I
% grew that to 110% because it was too short. Hence there are copies
% of ot1ppl.fd and pslatex.sty in the source directory which should
% override the ones in a normal LaTeX distribution.
