% \section{Overview}
%
% This suite of \LaTeX\ bits is intended to provide some configurability
% for the fonts used by documents.  It lets users define their favourite
% collection of fonts, and any documents using this package will
% automatically honour those design decisions.
%
% It goes a little beyond this brief, however, by supplying some missing
% PostScript fonts which may be useful.  (Well, the author uses them a lot.)
% In particular:
% \begin{itemize}
% \item The `squashed' Courier from David Carlisle's \package{pslatex}
%   package is included, and extended to cover the other known variants of
%   Courier (e.g., bold and oblique).
% \item A maths symbol font for Palatino has been added.  It works in a
%   similar way to the \package{mathptm} package's support for Times (i.e.,
%   it grabs glyphs from the normal Palatino font, and from the Computer
%   Modern symbols).
% \end{itemize}
%
%
% \section{Installing \package{mdwfonts}}
%
% The package comes with a large number of miscellaneous font files.  They
% ought to be placed in appropriate directories where \TeX\ and/or other
% programs can find them.  Exactly where this will be depends heavily on your
% installation: try looking for the other fonts and put these with them.
% The various extensions for the font files are:
% \begin{description}
% \item [.tfm] is a \TeX\ Font Metric file, needed by \TeX.
% \item [.vf] is a virtual font description file, needed by DVI-drivers.
% \item [.fd] is a font description file, required by \LaTeX.
% \end{description}
%
% You'll also need to put |mdwfonts.sty| somewhere where \LaTeX\ will find
% it.  What you do with the documentation file is up to you.
%
% The files |mTTpcr.fd| and |mdwfonts.sty| may not have been included in
% your distribution.  If you don't have them, run \LaTeX\ on |mdwfonts.ins|
% to build them.  I'm explicitly not giving instructions for building all
% the other font files, because I'd much prefer it if they were distributed
% as they are, please -- building them is a fiddly business, and I'd rather
% that only I had to do it.
%
% Once you've done all that, you must tell \textit{dvips} about your new
% fonts, so add the following lines to the |psfonts.map| file, unless they're
% already there:
% \begin{listing}
%pcrb8rn Courier-Bold ".85 ExtendFont TeXBase1Encoding ReEncodeFont" <8r.enc
%pcrbo8rn Courier-BoldOblique ".85 ExtendFont TeXBase1Encoding ReEncodeFont" <8r.enc
%pcrr8rn Courier ".85 ExtendFont TeXBase1Encoding ReEncodeFont" <8r.enc
%pcrro8rn Courier-Oblique ".85 ExtendFont TeXBase1Encoding ReEncodeFont" <8r.enc
% \end{listing}
% The |pcrr8rn| line will already be in the file if you've installed the
% \package{pslatex} package, so don't bother putting it in again.
%
%
% \section{Using \package{mdwfonts}}
%
% \subsection{Defining fonts to use}
%
% The font faces you can use, with their names as used by this package,
% currently are:
% \begin{itemize}
% \item Computer Modern Roman (|cmr|)
% \item Computer Modern Sans (|cmss|)
% \item Times Roman (|times|)
% \item Helvetica (|helvetica|)
% \item Palatino (|palatino|)
% \item Computer Modern Typewriter (|cmtt|)
% \item Courier (condensed version) (|courier|)
% \end{itemize}
% Only Computer Modern Roman, Times Roman and Palatino may be used as a maths
% family.
%
% The \package{mdwfonts} package knows about five font families which
% documents probably want to use.  The available families you can set, with
% their names as used by this package, are:
% \begin{description}
% \item [The body text family] (|body|) is the main font your document uses.
%   The default body family is Computer Modern Roman.
% \item [The maths family] (|maths|) is the font used for mathematics.
%   The default maths family is the same as the body family.
% \item [The sans serif family] (|sans|) is used for sans serif text.
%   The default sans serif family is Computer Modern Sans.
% \item [The headings family] (|head|) is used for headings, if your
%   document class supports this.\footnote{
%     The \texttt{\char`\\headfam} command is configured to change to the
%     chosen headings family.  Co-operating document classes should use this
%     hook when typesetting chapter and section headings, etc.}
%   Most document classes don't support this, but \package{mdwfonts} patches
%   the standard \LaTeX\ classes so that they work.  The default headings
%   family is Computer Modern Roman.
% \item [The typewriter family] (|tt|) is used for monospaced text.  The
%    default typewriter family is Computer Modern Typewriter.
% \end{description}
% American users not used to spelling \lit{maths} correctly may use the
% alternative spelling \lit{math} instead.  If only the rest of \LaTeX\ were
% this considerate.
%
%
% \subsection{Assigning faces to families}
%
% \DescribeMacro\mdwfont
% This is fairly simple, really.  The |\mdwfont| will attach a typeface to a
% given family.  The syntax is as follows:
% \begin{syntdiag}
% "\\mdwfont" "{" \< <family-name> "=" <face-name> \\ "," \> "}"
% \end{syntdiag}
% For example, saying
% \begin{listing}
%\mdwfont{body=palatino, maths=palatino,
%         sans=helvetica, head=helvetica
%         tt=courier}
% \end{listing}
% uses Palatino for the main body text, and for maths, Helvetica for sans
% serif text, and for headings (again, only if your document class supports
% this).
%
% The \package{mdwfonts} package also supports a collection of options which
% may be passed to the package.  The syntax of the package invocation is:
% \begin{syntdiag}
% "\\usepackage"
% \[ "["
%   \< \( <face-name> \\ <family-name> "=" <face-name> \) \\ "," \>
% "]" \]
% \\
% "{" "mdwfonts" "}"
% \end{syntdiag}
%
% A face name on its own configures families sensibly to use that face.
% The actual behaviour is as follows:
% \begin{description}
% \item [times] Set body and maths families to Times Roman.
% \item [palatino] Set body and maths families to Palatino.
% \item [cmr] Set body, headings and maths families to Computer Modern Roman.
% \item [helvetica] Set sans serif and headings families to Helvetica.
% \item [cmss] Set sans serif family to Computer Modern Sans.
% \item [courier] Set typewriter family to Courier.
% \item [cmtt] Set typewriter family to Computer Modern Typewriter.
% \end{description}
% Astute readers will be able to deduce the author's personal preferences
% for assigning typefaces to families from the above rules.  However, they
% should suffice for most simple configurations.  Moreover, the direct
% assignment of faces to families is supported in case the above aren't
% expressive enough.
%
% When \package{mdwfonts} starts up, it reads a file called |mdwfonts.cfg|,
% if it exists.  This file should set up defaults for the various families
% according to the user's preferences.  The decisions made by the
% configuration file may be overridden by the document, however, since
% package options are processed after running |mdwfonts.cfg|.

% \implementation
%
% \section{The package}
%
%    \begin{macrocode}
%<*sty>
%    \end{macrocode}
%
%
% \subsection{Options handing}
%
% There are several font choices to be made.  These can be made from the
% package options or the configuration file; the former takes precedence over
% the latter.
%
% I'll use David Carlisle's rather good \package{keyval} package to handle
% this lot because it saves a lot of hassle in the long run.
%
%    \begin{macrocode}
\RequirePackage{keyval}
%    \end{macrocode}
%
% Now to define how all this actually works.  Maintain a variable for each
% family that I understand, and a list of which fonts people have expressed
% an interest in.
%
%    \begin{macrocode}
\def\mdwf@bodyfont{\mdwf@cmr}
\def\mdwf@mathsfont{\mdwf@bodyfont}
\def\mdwf@sansfont{\mdwf@cmss}
\def\mdwf@headfont{\mdwf@cmr}
\def\mdwf@ttfont{\mdwf@cmtt}
%    \end{macrocode}
%
% Now to define the keys and values which I'll accept.
%
%    \begin{macrocode}
\def\mdwf@set#1#2{\edef#1{\expandafter\noexpand\csname mdwf@#2\endcsname}}
\define@key{mdwf}{body}{\mdwf@set\mdwf@bodyfont{#1}}
\define@key{mdwf}{maths}{\mdwf@set\mdwf@mathsfont{#1}}
\define@key{mdwf}{math}{\mdwf@set\mdwf@mathsfont{#1}}
\define@key{mdwf}{sans}{\mdwf@set\mdwf@sansfont{#1}}
\define@key{mdwf}{head}{\mdwf@set\mdwf@headfont{#1}}
\define@key{mdwf}{tt}{\mdwf@set\mdwf@ttfont{#1}}
%    \end{macrocode}
%
% Now input the configuration file.
%
%    \begin{macrocode}
\def\mdwfont{\setkeys{mdwf}}
\@input{mdwfonts.cfg}
%    \end{macrocode}
%
% Set up some package options which handle the common cases.  Then add
% a catch-all option which just gets bundled to \package{keyval}.
%
%    \begin{macrocode}
\DeclareOption{times}{\mdwfont{body=times, maths=times}}
\DeclareOption{palatino}{\mdwfont{body=palatino, maths=palatino}}
\DeclareOption{cmr}{\mdwfont{body=cmr, maths=cmr, head=cmr}}
\DeclareOption{helvetica}{\mdwfont{sans=helvetica, head=helvetica}}
\DeclareOption{cmss}{\mdwfont{sans=cmss}}
\DeclareOption{courier}{\mdwfont{tt=courier}}
\DeclareOption{cmtt}{\mdwfont{tt=cmtt}}
\DeclareOption*{\expandafter\mdwfont\expandafter{\CurrentOption}}
\ProcessOptions*
%    \end{macrocode}
%
% Now, if a client wants a really odd setup not provided by the above
% interface, it can define |\mdwfonts| to declare its decision.
%
%    \begin{macrocode}
\ifx\mdwfonts\@@undefined\else
  \def\@tempa#1\@@{\mdwfont{#1}}
  \expandafter\@tempa\mdwfonts\@@
\fi
%    \end{macrocode}
%
%
% \subsection{Setting up the actual fonts}
%
% \begin{macro}{\mdwf@iffont}
%
% I need to check whether a font's been used.  This macro will help.
%
% First, I'll define some numeric values for various fonts.
%
%    \begin{macrocode}
\count@\z@
\def\@tempa#1{%
  \expandafter\chardef\csname mdwf@#1\endcsname\count@%
  \advance\count@\@ne%
}
\@tempa{cmr}\@tempa{cmss}\@tempa{cmtt}
\@tempa{times}\@tempa{palatino}\@tempa{helvetica}\@tempa{courier}
%    \end{macrocode}
%
% And now to check whether a font is being used.  This is rather horrible.
%
%    \begin{macrocode}
\def\mdwf@iffont#1{\if1%
  \ifnum\mdwf@bodyfont=#11\else%
  \ifnum\mdwf@headfont=#11\else%
  \ifnum\mdwf@sansfont=#11\else%
  \ifnum\mdwf@ttfont=#11\else0%
  \fi\fi\fi\fi%
}
%    \end{macrocode}

% \subsubsection{Text fonts}
%
% \paragraph{Courier}
% The Courier family is redefined in its entirety here.  I use the condensed
% Courier provided by David Carlisle's \package{pslatex} package, although
% I've extended it to cover all the shapes and not just medium roman.
