%  \section{The German language}
%
%    The file \file{\filename}\footnote{The file described in this
%    section has version number \fileversion\ and was last revised on
%    \filedate.}  defines all the language definition macros for the
%    German language as well as for the Austrian dialect of this
%    language\footnote{This file is a re-implementation of Hubert
%    Partl's \file{german.sty} version 2.5b, see~\cite{HP}.}.
%
%    For this language the character |"| is made active. In
%    table~\ref{tab:german-quote} an overview is given of its
%    purpose. One of the reasons for this is that in the German
%    language some character combinations change when a word is broken
%    between the combination. Also the vertical placement of the
%    umlaut can be controlled this way.
%    \begin{table}[htb]
%     \begin{center}
%     \begin{tabular}{lp{8cm}}
%      |"a| & |\"a|, also implemented for the other
%                  lowercase and uppercase vowels.                 \\
%      |"s| & to produce the German \ss{} (like |\ss{}|).          \\
%      |"z| & to produce the German \ss{} (like |\ss{}|).          \\
%      |"ck|& for |ck| to be hyphenated as |k-k|.                  \\
%      |"ff|& for |ff| to be hyphenated as |ff-f|,
%                  this is also implemented for l, m, n, p, r and t\\
%      |"S| & for |SS| to be |\uppercase{"s}|.                     \\
%      |"Z| & for |SZ| to be |\uppercase{"z}|.                     \\
%      \verb="|= & disable ligature at this position.              \\
%      |"-| & an explicit hyphen sign, allowing hyphenation
%             in the rest of the word.                             \\
%      |""| & like |"-|, but producing no hyphen sign
%             (for compund words with hyphen, e.g.\ |x-""y|).      \\
%      |"~| & for a compound word mark without a breakpoint.       \\
%      |"=| & for a compound word mark with a breakpoint, allowing
%             hyphenation in the composing words.                  \\
%      |"`| & for German left double quotes (looks like ,,).       \\
%      |"'| & for German right double quotes.                      \\
%      |"<| & for French left double quotes (similar to $<<$).     \\

%              by \file{german.ldf}}\label{tab:german-quote}
%     \end{center}
%    \end{table}
%    The quotes in table~\ref{tab:german-quote} can also be typeset by
%    using the commands in table~\ref{tab:more-quote}.
%    \begin{table}[htb]

%      |\frq|  & for (French) right single quotes (similar to $>$). \\
%      |\dq|   & the original quotes character (|"|).        \\
