%    \subsection{Compatibility Definitions}
%
%    Since we want to use this style with \LaTeX\,2.09 and \LaTeXe{} we have
%    to define a common interface. For this purpose we use a subset of
%    the style writers interface already defined for \LaTeXe{} style
%    writers. Since some macros are not defined in \LaTeX\,2.09 we
%    implement them --- at least to the degree needed here.
%
%    \begin{macrocode}
\ifOldLaTeX
%    \end{macrocode}
%
%    Just for fun we define some font switching commands. In fact the
%    behaviour in \LaTeXe{} is more complex. But I think these
%    definitions are enough to avoid errors.

%    \subsection{Useful Macros}
%
%    This section contains some useful abbreviations. They are mainly
%    some kind of logos.
%
%   The following hack is from Bernd Raichle.
%
%   Fuer LaTeX 2.09 (mit oder ohne NFSS) benoetigen wir noch
%   so etwas wie \verb|\smaller| aus dem veralteteten `smaller.sty',
%   um SmallCaps fuer (fast) alle Schriftarten nachzubilden.
%   Fuer SmallCaps muss jedoch um mehr Schriftgrade als bei
%  \verb|\smaller| verkleinert werden, so dass hier eine neue
%   Definition namens \verb|\logo@smaller| folgt, deren Verkleinerung
%   sich an den `math sizes' (hier: \verb|\scriptfont<fam>|) orientiert,
%   die standardmaessig mit \LaTeX2e definiert werden.
%

  % `math group/fam', die in den Makros in der Datei
  % "lfonts.tex" entsprechend mit veraendert wird.

%    \subsubsection{Macros from texnames.sty}
%
%    The following macros are taken from the file {\tt texnames.sty}
%    version \verb|1.09| from \verb|<16 March 1993>| by Nelson
%    H.\,F.~Beebe. I have simply included the definitions here to avoid
%    additional files to be distributed with dtk.dtx. The original
%    documentation has been wrapped into the doc format. And here it goes:
%
%    In the following, we first give the ``official'' definition,
%    then follow it with spelling variants.  Alternate definitions
%    are discarded in favor of the official one.  Each family is
%    separated by a line like the following one.
%   
%    \begin{macro}{\TeX}
%    Only change from plain.tex is the \verb|\spacefactor| assignment
%    (suggested by Phil Taylor), so that \TeX\ at the end of a
%    sentence isn't treated as an abbreviation.
%
%    \begin{macrocode}
\renewcommand\TeX{T\kern-.1667em\lower.5ex\hbox{E}\kern-.125emX%
  \spacefactor1000 }
%    \end{macrocode}

%
%    \begin{macro}{\AmS}
%    From the AMS tex/ams/amslatex/fontsel/nfssinst.tex file:
%    \begin{macrocode}
\@ifundefined{AmS}{%
  \def\AmS{\(\cal A\)\kern-.1667em\lower.5ex\hbox

%    \end{macro}
%
%    \begin{macro}{\AmSTeX}
%    Mike Spivak's amstex/amstex.tex 1.1d [26-Aug-1988] has\\
%    \verb|\def\AmSTeX{{\textfontii A}\kern-.1667em\lower.5ex\hbox|\\
%    \verb|            {\textfontii M}\kern-.125em{\textfontii S}-\TeX}|\\
%    and 2.1 [05-Apr-1991] has an equivalent definition.
%    AmSTeX's \verb|\textfontii| is exactly the same as \verb|\cal|, which
%    all \TeX variants understand.
%
%    \begin{macrocode}

%
%    \begin{macro}{\AMSTEX}

%    draft of the book) defines it in uppercase with the standard
%    definition.
%    \begin{macrocode}
\@ifundefined{AMSTEX}{\let\AMSTEX=\AmSTeX}{}
%    \end{macrocode}
%    \end{macro}
%
%    \begin{macro}{\AMSTEX}
%    Barbara Beeton's latex/deproc.sty [24-Apr-1986] and inputs/tugbot.sty
%    [11-Jan-1988] uses this spelling, but the definition\\

%    \end{macro}
%
%    \begin{macro}{\BibTeX}
%    The definitions of \verb|\BibTeX| and \verb|\SLiTeX| in Leslie Lamport's
%    latex/local.tex lower the E by 0.7ex, while \TeX in plain.tex lowers
%    it by 0.5ex.  Oren Patashnik's bibtex/btxdoc.tex and bibtex/btxhak.tex
%    [08-Feb-1988] and bibtex/bibtex.web 0.99c [xx-Feb-1988] use this same
%    name and definition, but Oren said using \TeX here is ok.  (Curiously,
%    \LaTeX itself does not define macros for any \TeX ware except \LaTeX and
%    \TeX!)
