% \section{Introduction}
% 
% {\em This is a draft of the documentation.  I hope to improve it
% someday.}
% 
% This document describes a set of \LaTeX\ style files for using
% PostScript fonts in \LaTeX\ documents.  The macros use the New Font
% Selection Scheme (NFSS) of Frank Mittelbach and Rainer
% Sch{\"o}pf~\cite{MittelbachSc89a,MittelbachSc90} to define font
% families for the most common PostScript fonts.  In addition, the
% macros are customized for use with Tomas Rokicki's {\tt
% dvips}~\cite{Rokicki91}.  Although it would be simple to modify
% these macros for use with other DVI-to-PostScript drivers (all that
% is required is that the names of the TFM files be changed), the
% results will not be as satisfactory, since only {\tt dvips} makes
% use of the virtual font technology~\cite{Knuth90b} which solves many
% of the traditional problems associated with using PostScript fonts
% in \TeX\ documents.
% 
% Although {\tt dvips} and the NFSS solve many of the tradtional
% problems with PostScript fonts, there is at least one issue
% unresolved: the x-heights of the PostScript fonts are usually
% noticeably different from the x-heights of Computer Modern fonts.
% For example, the x-height of {\tt cmmi10} is approximately 4.31\,pt.
% The x-height of 10 point Times Roman is 4.48\,pt.  This means that if
% math text is imbedded in the middle of Times Roman text, the result
% is visually somewhat jarring because of the difference in x-heights
% of the text and math fonts.  One solution is to scale the PostScript
% fonts down so that their x-heights match the x-heights of {\tt
% cmmi10}.  For example, to define the ``10 point'' Times Roman font,
% we actually load Times-Roman at 9.62\,pt.  Credit goes to Professor
% Robert Berwick for pointing out this problem and suggesting the
% solution.
% 
% All of the x-heights mentioned below are for the 10\,pt design size
% of the font.
% 
% \section{The user interface}
% 
% There are two basic ways of using the package.  First, you can use
% the |psfonts| document style option to define all of the PostScript
% font families, without actually affecting the default font.  Then,
% for example, you could type
% \begin{flushleft}
% |{\family{times}\selectfont This is Times-Roman.}|
% \end{flushleft}
% to typeset a phrase in Times-Roman.
% 
% If, however, you want to actually typeset your entire document in a
% PostScript font, you should use one of the following documentstyle
% options.
% \begin{description}
% 
% \item[avantgarde] Makes Avant Garde Book the default text font.
% 
% \item[bookman] Makes Bookman Light the default text font.
% 
% \item[helvetica] Makes Helvetica  the default text font.
% 
% \item[ncs] Makes New Century Schoolbook Roman the default text font.
% 
% \item[palatino] Makes Palatino Roman the default text font.
% 
% \item[times] Makes Times Roman the default text font.
% 
% \end{description}
% For a complete description of the fonts used in each of these style
% files, see Section~\ref{sec:fsf}

% \section{The implementation}
% 
% As usual, we first check to see if the file has already been loaded
% and quit immediately it has been.

% Unlike the font family definitions for the standard Computer Modern
% fonts, the PostScript families are all quite uniform, since, for
% example, we never run into the case where a font is available at one
% size, but not at another.  So, we now define some macros to take
% advantage of this uniformity and make the font definitions simpler.
% These macros are mostly due to Timothy Van Zandt $\langle${\tt
% tvz@princeton.edu}$\rangle$, with a few modifications by David
% Jones.

% Now we present the definitions of the various font families.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

%% \subsection{PostScript Avante Garde family}
%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% AvantGarde-Book has an x-height of 5.47\,pt, so we scale the fonts
% by $4.30554\,{\rm pt}/5.47\,{\rm pt} \approx 0.7871$.
%    \begin{macrocode}
\scale@stdsizes{.7871}
%    \end{macrocode}
% AvantGarde exists in four basic shapes: AvantGarde-Book (pagk), the
% basic ``roman'' text font; AvantGarde-BookOblique (pagko), a slanted
% version of the font; AvantGarde-Demi (pagd), a bolder version of the
% font; and AvantGarde-DemiOblique (pagdo), a slanted bold version of
% the font.  In addition, {\tt dvips} defines a smallcaps face (pagkc)
% as a virtual font.  (Note: for an explanation of the font names, see
% Section~6 (``Font Naming Conventions'') of the {\tt dvips}
% manual~\cite{Rokicki91}.)
%    \begin{macrocode}
\new@psfontshape{avantgarde}{m}{n}{pagk}

\new@psfontshape{avantgarde}{m}{sc}{pagkc}

\new@psfontshape{avantgarde}{m}{sl}{pagko}

\new@psfontshape{avantgarde}{bx}{n}{pagd}

\new@psfontshape{avantgarde}{bx}{sl}{pagdo}
%    \end{macrocode}
% There is no true italic face for AvantGarde, nor is there a bold
% italic or bold smallcaps font (though it would be possible to create
% the latter if necessary---see Section~5.2 of~\cite{Rokicki91}).
%    \begin{macrocode}
\subst@fontshape{avantgarde}{m}{it}{avantgarde}{m}{sl}
\subst@fontshape{avantgarde}{bx}{it}{avantgarde}{bx}{sl}
\subst@fontshape{avantgarde}{bx}{sc}{avantgarde}{m}{sc}
%    \end{macrocode}
% No special action needs to be taken when these fonts are loaded.
%    \begin{macrocode}
\extra@def{avantgarde}{}{}
%    \end{macrocode}
% 
% For the most part, all of the following font definitions follow this
% general pattern and are self-explanatory.  Therefore, they are
% presented without further comment, except when something exceptional
% comes up.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

%% \subsection{PostScript Bookman family}
%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% Bookman-Light has an x-height of 4.84pt, so we scale these fonts by
% a factor of $4.30554/4.84 \approx .8895$.

%% \subsection{PostScript Courier family}
%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% Courier has an x-height of 4.37, so we scale it by $4.30554/4.37
% \approx .9852$.
%    \begin{macrocode}
\scale@stdsizes{.9852}
%    \end{macrocode}
% 
% The Courier family requires some explanation.  There is an
% influential body of opinion at my site which holds that the standard
% PostScript Courier fonts are too wide.  (Indeed, we are not alone in
% this; see, for example, ???.)  To solve this problem, I simply
% created a set of virtual fonts, Courier-Narrow (pcrrrc),
% (Courier-Narrow-Oblique) pcrroc, Courier-Narrow-Bold (pcrbrc) and
% Courier-Narrow-BoldOblique (pcrboc) to replace the standard fonts.
% These are, respectively, Courier, Courier-Oblique, Courier-Bold and
% Courier-BoldOblique shrank by \%15 in the horizontal direction.  For
% example, to create the ``Courier-Narrow'' font from Courier.afm (the
% Adobe Font Metric file for Courier), I executed the following
% commands:
% \begin{flushleft}\tt
% afm2tfm Courier.afm -e .875 -v pcrrrc rpcrrrc
% \end{flushleft}
% which created the virtual property list |pcrrrc.vpl| and the raw TFM
% file |rpcrrrc.tfm|, and
% \begin{flushleft}\tt
% vptovf pcrrrc.vpl pcrrrc.vf pcrrrc.tfm
% \end{flushleft}
% which created the virtual font file |pcrrc.vf| and the corresponding
% TFM file |pcrrc.tfm|.  Similar commands sufficed to create the other
% fonts.  Finally, I installed the following lines in the file
% |psfonts.map| so that {\tt dvips} would know about the new fonts:
% \begin{flushleft}\small\tt
% rpcrboc Courier-Narrow-BoldOblique "/Courier-BoldOblique .875 ExtendFont"\\
% rpcrbrc Courier-Narrow-Bold "/Courier-Bold .875 ExtendFont"\\
% rpcrroc Courier-Narrow-Oblique "/Courier-Oblique .875 ExtendFont"\\
% rpcrrrc Courier-Narrow "/Courier .875 ExtendFont"
% \end{flushleft}
% 
% Here is the definition of the |courier| family using the new virtual
% fonts:
%    \begin{macrocode}
\new@psfontshape{courier}{m}{n}{pcrr}   % was pcrrrc (Silvio Levy)
