%    \section{Aim and usage}
%
%    The \babel\ `language definition file' \file{germanb.ldf} documented in this manual provides
%    the \babel\ package with all language specific strings, settings and commands needed for writing
%    German texts, including texts in the Austrian and Swiss (standard) varieties of German, in \emph{traditional
%    (1901--1996) spelling}.\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}). Johannes Braams did the initial re-implementation.}
%    As for support for contemporary (`reformed', i.\,e., post-1996) German orthography, please refer to
%    the complementary \href{file:ngermanb.pdf}{manual for the \file{ngermanb.ldf} language definition file}.
%    The `language definition file' also assures that the correct hyphenation patterns for the respective
%    language or variety are used (see sec.~\ref{sec:patterns} for details).
%
%    In order to use the language definitions provided here, you need to use
%    the \babel\ package and pass the respective language\slash variety name as an
%    option, either of
%
%    \begin{itemize}
%       \setlength{\itemsep}{0pt}
%       \item |\usepackage[german]{babel}|
%       \item |\usepackage[austrian]{babel}|
%       \item |\usepackage[swissgerman]{babel}|
%       \item |\usepackage[swissgerman.toss]{babel}|\newfeature{2.10}\footnote{%
%              See sec.~\ref{sec:toss} on the \Lopt{toss} modifier.}
%    \end{itemize}
%    Using multiple varieties in parallel is possible;
%    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.
%    Some of these shorthands address a peculiarity of pre-1996 German
%    spelling: consonantial character combinations that change in the context
%    of hyphenations.
%    Other shorthands are provided for frequently used
%    special characters as well as for better control of hyphenation,
%    line breaks and ligatures.
%
%    Table~\ref{tab:german-quote} provides an overview of the shorthands
%    that are provided by \textsf{babel-german} for \Lopt{german}, \Lopt{austrian}
%    and \Lopt{swissgerman}.

%   \section{Hyphenation patterns}\label{sec:patterns}
%
%   The question which hyphenation patterns are used by \Babel\ in case of the varieties of German needs some elaboration.
%   There is a set of established hyphenation patterns for pre- and post-1996 German orthography that has been available
%   with \TeX\ distributions for a long time (currently, these are shipped in form of the \texttt{dehypht} and \texttt{dehyphn} files).
%   These patterns, though, have many flaws (they produce wrong hyphenations, and not much is known about their construction). Therefore, a group
%   of people developed completely new patterns that do much better, the so-called `experimental' new hyphenation patterns of German,
%   distributed in the \textsf{dehyph-exptl} package \cite{exptl}.
%   As opposed to the old patterns, the new ones undergo constant improvement. The price for this, however, is that hyphenation and thus
%   the typeset document is subject to change with, and only due to, pattern updates.
%
%   Modern engines (i.\,e., \texttt{xetex} and \texttt{luatex}) have already embraced those new patterns, i.\,e., they are activated on these engines by default.
%   The classic \TeX\ engines (\texttt{tex}\slash\texttt{pdftex}), however, haven't: they continue to use the old patterns. The reason for this is one
%   of \TeX's quality standards: refrain, if ever possible, from changing the output of user's documents in the wake of software updates.
%   An exception is (pre-1996) Swiss Standard German: here, the classic engines use the `experimental' patterns by default (since there were no patterns available
%   previously anyway).
%
%   So you need to explicitly activate the new patterns for a given document (except for \Lopt{swissgerman}) with the classic engines, should you
%   want to use them instead of the old ones.
%   With \Babel, this can be done quite easily by means of the \textsf{hyphsubst} \cite{hyphsubst} package:
%   \begin{verbatim}
%     \usepackage[german=german-x-latest]{hyphsubst}
%     \usepackage[german]{babel}
%   \end{verbatim}\vspace{-\baselineskip}
%   Since \Lopt{austrian} uses the same patterns as \Lopt{german}, the given \textsf{hyphsubst} option activates
%   the new patterns for this variety as well; but note that \textsf{hyphsubst} must be loaded before \babel\ (please refer to \cite{exptl} and 
%   \cite{hyphsubst} for details).
%
%   If you only want to use experimental patterns for one variety, you can do like so:
%   \begin{verbatim}
%     \usepackage{hyphsubst}
%     \usepackage[german,austrian]{babel}
%     \HyphSubstLet{austrian}{german-x-latest}
%   \end{verbatim}\vspace{-\baselineskip}
%
%
%   \section{Variety-specific options}\label{sec:toss}
%
%   In\newfeature{2.10} Swiss (and Liechtensteinian) German writing, the use of \graph{\ss} is rather uncommon.
%   Swiss writers would normally use \graph{ss} where German or Austrian writers use the \graph{\ss} character
%   (e.\,g., \emph{Bu\ss e} vs.\,\emph{Busse}). When texts (or names) from other German speaking areas are quoted,
%   however, the spelling and hence the \graph{\ss} is often maintained  (particularly in scholarly writing where
%   the spelling of quoted text is not supposed to be touched).
%
%   We assume that Swiss writers will normally input \graph{ss} directly when they mean \graph{ss}, and we assume furthermore
%   that the \graph{\ss}-related shorthands |"s| and |"z| are useful also for Swiss writers when they actually need \graph{\ss},
%   the more so since the \graph{\ss} is not as directly accessible on Swiss keyboards as it is on German and Austrian ones.
%   On the other hand, there might be occasions where writers want to transfer a text from German or Austrian Standard into Swiss
%   Standard German and adapt the spelling on the fly, i.\,e., transform all \graph{\ss} into \graph{ss}.
%
%   For this special case, we provide an option to make the \graph{\ss}-related shorthands |"s| and |"z| expand to the
%   respective digraphs\footnote{In graphematics, the term \emph{digraph} denotes two characters that make a functional pair
%   (which means, depending on the theoretical assumptions: they represent a single sound or they are semantically distinctive).},
%   \graph{ss} and \graph{sz}, rather than to \graph{\ss}. This is not the default behavior with
%   \Lopt{swissgerman} since, as mentioned, there are situations when the \graph{\ss} is (and has to be) used in Swiss writing,
%   and normally, no shorthand is needed to input (or output) two simple \graph{s} characters. You can opt-in (and out) digraphical
%   expansion of |"s| and |"z| on a global and local level:
%   \begin{itemize}
%   \item To globally switch on the digraphical expansion, use the \Babel\ modifier \Lopt{toss} (read: `to \graph{ss}') with
%         \Lopt{swissgerman}. I.\,e., pass \Lopt{swissgerman.toss} (rather than \Lopt{swissgerman}) as \babel\ option.
%
%   \item To switch on the digraphical expansion only locally, you can use the boolean switch |\tosstrue|. Likewise,
%         |\tossfalse| switches off (both locally and globally set) digraphical expansion.
%   \end{itemize}
%   Both these changes result in the following deviant behavior of two shorthands:
%    \begin{table}[!h]
%     \begin{tabular}{l>{\raggedright}p{.9\textwidth}}
%      |"s|	& 	Expands to digraph \graph{ss}             \tabularnewline
%      |"z|	& 	Expands to digraph \graph{sz}             \tabularnewline
%     \end{tabular}
%    \end{table}
%
%    \noindent One further note related to the use of \graph{ss} in Swiss Standard German. As opposed to other consonantial letters, the \graph{s}
%    is excluded from the three consonant rule (\emph{Dreikonsonantenregel}) of traditional German spelling which prescribes
%    that one of three identical consonants has to be omitted if a vowel follows the three consonants (i.\,e., \emph{Schiffahrt},
%    not \emph{Schifffahrt}), except if the word is hyphenated (\emph{Schiff-fahrt}); the shorthands |"ff| etc. account for that.
%    This does not apply to \graph{s}! In that case, always all three consonants are spelled out (e.\,g., \emph{Kongresssaal},
%    not \emph{Kongressaal}). This is why we don't provide a shorthand for the \graph{sss} case.
