% \section{Internationalizing \LaTeX{} 2.09}
%
% Now that we're sure that the code is seen by \LaTeX\ only, we
% have to find out what the main (primary) document style is
% because we want to redefine some macros. This is only necessary
% for releases of \LaTeX\ dated before December~1991. Therefore
% this part of the code can optionally be included in
% \file{babel.def} by specifying the \texttt{docstrip} option
% \texttt{names}.
%
% The standard styles can be distinguished by checking whether some
% macros are defined. In table~\ref{styles} an overview is given of
% the macros that can be used for this purpose.
% \begin{table}[htb]
% \begin{center}
% \DeleteShortVerb{\|}
% \begin{tabular}{|lcp{8cm}|}
% \hline
% article & : & both the \verb+\chapter+ and \verb+\opening+
% macros are undefined\\
% report and book & : & the \verb+\chapter+ macro is defined and
% the \verb+\opening+ is undefined\\
% letter & : & the \verb+\chapter+ macro is undefined and
% the \verb+\opening+ is defined\\
% \hline
% \end{tabular}
% \caption{How to determine the main document style}\label{styles}
% \MakeShortVerb{\|}
% \end{center}
% \end{table}
%
% \noindent The macros that have to be redefined for the
% \texttt{report} and \texttt{book} document styles happen to be
% the same, so there is no need to distinguish between those two
% styles.
%
% \begin{macro}{\doc@style}
% First a parameter |\doc@style| is defined to identify the current
% document style. This parameter might have been defined by a
% document style that already uses macros instead of hard-wired
% texts, such as \file{artikel1.sty}~\cite{BEP}, so the existence of
% |\doc@style| is checked. If this macro is undefined, i.\,e., if
% the document style is unknown and could therefore contain
% hard-wired texts, |\doc@style| is defined to the default
% value~`0'.
% \changes{babel~3.0d}{1991/10/29}{Removed use of \cs{@ifundefined}}
% \begin{macrocode}
%<*names>
\ifx\@undefined\doc@style
\def\doc@style{0}%
% \end{macrocode}
% This parameter is defined in the following \texttt{if}
% construction (see table~\ref{styles}):
%
% \begin{macrocode}
\ifx\@undefined\opening
\ifx\@undefined\chapter
\def\doc@style{1}%
\else
\def\doc@style{2}%
\fi
\else
\def\doc@style{3}%
\fi%
\fi%
% \end{macrocode}
% \end{macro}
%
% \changes{babel~3.1}{1991/11/05}{Removed definition of
% \cs{if@restonecol}}
%
% Now here comes the real work: we start to redefine things and
% replace hard-wired texts by macros. These redefinitions should be
% carried out conditionally, in case it has already been done.
%
% For the \texttt{figure} and \texttt{table} environments we have
% in all styles:
% \begin{macrocode}
\@ifundefined{figurename}{\def\fnum@figure{\figurename{} \thefigure}}{}
\@ifundefined{tablename}{\def\fnum@table{\tablename{} \thetable}}{}
% \end{macrocode}
%
% The rest of the macros have to be treated differently for each
% style. When |\doc@style| still has its default value nothing
% needs to be done.
% \begin{macrocode}
\ifcase\doc@style\relax
\or
% \end{macrocode}
%
% This means that \file{babel.def} is read after the
% \texttt{article} style, where no |\chapter| and |\opening|
% commands are defined\footnote{A fact that was pointed out to me
% by Nico Poppelier and was already used in Piet van Oostrum's
% document style option~\texttt{nl}.}.
%
% First we have the |\tableofcontents|,
% |\listoffigures| and |\listoftables|:
% \begin{macrocode}
\@ifundefined{contentsname}%
{\def\tableofcontents{\section*{\contentsname\@mkboth
{\uppercase{\contentsname}}{\uppercase{\contentsname}}}%

\@ifundefined{listfigurename}%

\@ifundefined{listtablename}%
{\def\listoftables{\section*{\listtablename\@mkboth

% \end{macrocode}
%
% Then the |\thebibliography| and |\theindex| environments.
%
% \begin{macrocode}
\@ifundefined{refname}%
{\def\thebibliography#1{\section*{\refname

\list{[\arabic{enumi}]}{\settowidth\labelwidth{[#1]}%

% \end{macrocode}

% The |abstract| environment:

{\bf \abstractname\vspace{-.5em}\vspace{\z@}}%

% \end{macrocode}
%
% And last but not least, the macro |\part|:
%
% \begin{macrocode}
\@ifundefined{partname}%

% \end{macrocode}
%
% This is all that needs to be done for the \texttt{article} style.
%
% \begin{macrocode}
\or
% \end{macrocode}
%
% The next case is formed by the two styles \texttt{book} and
% \texttt{report}. Basically we have to do the same as for the
% \texttt{article} style, except now we must also change the
% |\chapter| command.
%
% The tables of contents, figures and tables:
% \begin{macrocode}
\@ifundefined{contentsname}%
{\def\tableofcontents{\@restonecolfalse
\if@twocolumn\@restonecoltrue\onecolumn
\fi\chapter*{\contentsname\@mkboth
{\uppercase{\contentsname}}{\uppercase{\contentsname}}}%
\@starttoc{toc}%

\@ifundefined{listfigurename}%

\@starttoc{lot}%
\csname if@restonecol\endcsname\twocolumn
\csname fi\endcsname}}{}
% \end{macrocode}
%
% Again, the |bibliography| and |index| environments; notice that
% in this case we use |\bibname| instead of |\refname| as in the
% definitions for the \texttt{article} style. The reason for this
% is that in the \texttt{article} document style the term
% `References' is used in the definition of |\thebibliography|. In
% the \texttt{report} and \texttt{book} document styles the term
% `Bibliography' is used.
% \begin{macrocode}

% Here is the |abstract| environment:

{\def\abstract{\titlepage

% And last but not least the |\chapter|, |\appendix| and
% |\part| macros.
% \begin{macrocode}
\@ifundefined{chaptername}{\def\@chapapp{\chaptername}}{}
%
\@ifundefined{appendixname}%
{\def\appendix{\par

%
% Now we address the case where \file{babel.def} is read after the
% \texttt{letter} style. The \texttt{letter} document style
% defines the macro |\opening| and some other macros that are
% specific to \texttt{letter}. This means that we have to redefine
% other macros, compared to the previous two cases.
%
% First two macros for the material at the end of a letter, the
% |\cc| and |\encl| macros.
% \begin{macrocode}
\@ifundefined{ccname}%
{\def\cc#1{\par\noindent
\parbox[t]{\textwidth}%
{\@hangfrom{\rm \ccname : }\ignorespaces #1\strut}\par}}{}
\@ifundefined{enclname}%
{\def\encl#1{\par\noindent
\parbox[t]{\textwidth}%
{\@hangfrom{\rm \enclname : }\ignorespaces #1\strut}\par}}{}
% \end{macrocode}
%
% The last thing we have to do here is to redefine the
% \texttt{headings} pagestyle:
% \changes{babel~3.3}{1993/07/11}{\cs{headpagename} should be
% \cs{pagename}}
% \begin{macrocode}
\@ifundefined{headtoname}%
{\def\ps@headings{%
\def\@oddhead{\sl \headtoname{} \ignorespaces\toname \hfil
\@date \hfil \pagename{} \thepage}%
\def\@oddfoot{}}}{}
\fi
%</names>
% \end{macrocode}
%
% This was the last of the four standard document styles, so if
% |\doc@style| has another value we do nothing and just close the
% \texttt{if} construction. Here ends the code that can be optionally
% included when a version of \LaTeX\ is in use that is dated
% \emph{before} December~1991.
%
% We also need to redefine a number of commands to ensure that the
% right font encoding is used, but this can't be done before
% \file{babel.def} is loaded.
% \changes{babel~3.6o}{1999/04/07}{Moved the rest of the font encoding
% related definitions to their original place}
