%         Current maintainer. Address correspondence to juergen (at) spitzmueller (dot) org.}}

%  \maketitle
%
%    \begin{abstract}
%      \noindent This manual documents the \babel\ language definition file \file{germanb.ldf}
%      for German (traditional orthography).
%      The file is part of the \textsf{babel-german} bundle.
%    \end{abstract}
%
%    \section{Aim and usage}
%
%    The file \file{germanb.ldf} provides the \babel\ package with all language definition
%    macros (language specific strings and settings) for the German language, including
%    the Austrian and Swiss varieties of German. Furthermore, it assures that the
%    correct hyphenation patterns for the respective language or variety are
%    used.\footnote{The file \file{germanb.ldf} started as a re-implementation of the package
%    \file{german.sty} (v.\,2.5b), which was originally developed by Hubert Partl
%    (cf. \cite{HP}) and later maintained by Bernd Raichle (cf. \cite{gerdoc}).
%    The re-implementation was done by Johannes Braams.}
%    The file adheres to the traditional (1901--1996) orthography.
%    For reformed (post-1996) German orthography support, please refer to the
%    complementary |ngermanb.ldf| file.
%
%    In order to use the language definitions provided here, you need to use
%    the \babel\ package and pass the respective language name as an
%    option, either of
%
%    \begin{itemize}
%       \setlength{\itemsep}{0pt}
%       \item |\usepackage[german]{babel}|
%       \item |\usepackage[austrian]{babel}|
%       \item |\usepackage[swissgerman]{babel}|
%    \end{itemize}
%    Please consult the \babel\ manual \cite{babel} for details.
%
%    \section{Shorthands}
%
%    For all three varieties of German, the character |"| is made active
%    in order to provide some shorthand macros.
%    One purpose of these shorthands is to get control over a
%    peculiarity of traditional German spelling: some consonantial
%    character combinations change in the context of hyphenations.
%    Furthermore, the shorthands provide access to some frequently
%    used special characters as well as some further possibilities
%    to control hyphenation, to break lines and to deal with ligatures.
%    Table~\ref{tab:german-quote} provides an overview of the shorthands
%    that are provided by \file{germanb.ldf}.
%
%    \begin{table}[htb]
%     \begin{center}
%     \begin{tabular}{lp{.75\textwidth}}
%      |"a| & umlaut \"a (shorthand for |\"a|). Similar shorthands are
%                  available for all other lower- and uppercase
%                  vowels (umlauts: |"a|, |"o|, |"u|, |"A|, |"O|,
%                  |"U|, as well as tremata: |"e|, |"i|, |"E|, |"I|).\\
%      |"s| & German \ss{} (shorthand for |\ss{}|).                \\
%      |"z| & German \ss{} (shorthand for |\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| & |SS| (|\uppercase{"s}|, since \ss{} must be written
%                  as SS -- or SZ, see below -- in uppercase writing).\\
%      |"Z| & |SZ| (|\uppercase{"z}|, since \ss{} must be written
%                  as SZ -- or SS, see above -- in uppercase writing).\\
%      \verb="|= & disable ligature at this position
%                  (e.\,g. \verb=Auf"|lage=).                      \\
%      |"-| & an additional breakpoint that does still
%             allow for hyphenation at the breakpoints preset in
%             the hyphenation patterns (as opposed to |\-|).       \\
%      |""| & a breakpoint that does not output a hyphen sign
%             if the line break is performed (useful for compound
%             words with hyphen, e.\,g.\ |(Un-)""Sinn|).           \\
%      |"~| & a compound word mark without a breakpoint. Useful for
%              cases such as |bergauf und "~ab|.          \\
%      |"=| & a compound word mark with a breakpoint, allowing
%             for hyphenation at the other points preset in the
%             hyphenation patterns (as opposed to plain |-|).      \\
%      |"`| & German left double quotes (i.\,e. ,,).               \\
%      |"'| & German right double quotes (i.\,e. ``).              \\

%
%  \Babel\ expects a \file{\langvar{}.ldf} file for each \langvar. So we create portmanteau

%    For some \texttt{austrian} and \texttt{german}, this is not strictly necessary,
%    since \babel\ provides aliases for these languages (pointing to \texttt{germanb}).
%    However, since \babel\ does not officially support these aliases anymore after
%    the language definition files have been separated from the core, we provide
%    the whole range of ldf files for the sake of completeness.} These files themselves
%    only load \file{germanb.ldf}, which does the real work:
