% \section{Introduction}
%
% This file contains the external font information for special
% variants of the Computer Modern fonts to be used for overhead
% slides. They allow to produce slides in a similar fashion as it was
% originally done by \SliTeX{}.
%
% With \LaTeXe{} it is now no longer necessary to maintain a special
% format. Instead the standard format may be used and internally only
% different font definition files come into play.
%
% Note that you therefore can easily produce slides in different
% fonts just by calling an appropriate package (like |times|) in
% your |\usepackage| command. This works, for example, with all
% fonts that are defined to be scalable (eg PostScript fonts) since
% they can be scaled to any size.
%
% However, minor styles like |pandora| won't work because the standard
% |.fd| files shipped with \LaTeXe{} only contain small sizes. You can,
% of course, produce additional sizes and change the |.fd| files
% accordingly, but in this case it might be better to distinguish
% |.fd| files for normal text and for slides by prefixing the family
% name with an |l| (see below).
%
% All the standard family names for \SliTeX{} fonts start out with
% with an |l| as the first character. This will distinguish them from
% text font families with similar names.
%
% In addition, we introduce an additional convention for shapes: if
% $x$ is a shape, then |I|$x$ represents the invisible form of the
% shape. This is used by the color separation macros and the
% |\invisible| command of the slides style file.
%

% \section{A driver for this document}
%
% The next bit of code contains the documentation driver file for
% \TeX{}, i.e., the file that will produce the documentation you are
% currently reading. It will be extracted from this file by the
% \dst{} program.
% \changes{v2.1b}{1993/12/14}{Corrected \cs{documentclass}.}

%
% \section{The \dst{} modules}
%
% The following modules are used to direct \dst{} in
% generating external files:
% \begin{center}
% \begin{tabular}{ll}
%   driver & produce a documentation driver file \\
%   main   & generate \texttt{sfonts.def} \\
%   fd     & produce a font definition file \\
%   ec     & Use the extended EC font set rather than cm \\[2pt]
%   lccr    & Concrete Roman slide sizes \\
%   lcmss   & Computer Modern Sans slide sizes \\
%   lcmtt   & Computer Modern Typewriter slide sizes \\
%   lcmm    & Computer Modern Math italic slide sizes \\
%   lcmm    & Computer Modern Math symbols slide sizes \\
%   lcmex   & Computer Modern Math extension symbols slide sizes \\
%   llasy   & \LaTeX{} symbols slide sizes \\
% \end{tabular}
% \end{center}
% A typical \dst{} command file would then have entries like:
% \begin{verbatim}
%\generateFile{OMSlcmsy.fd}{t}{\from{slifonts.fdd}{lcmsy,fd}}
%\end{verbatim}
