%    \begin{abstract}
%      \noindent This manual documents \babel\ language support for German as provided by the
%      \babelde\ package.
%      The package supports all major (standard) varieties of German (i.\,e., Austrian, Swiss,
%      and German Standard German) in contemporary as well as in pre-1996 (i.\,e., 1901) spelling.
%    \end{abstract}

%
%    \section{Aims and Scope}
%
%    The \babelde\ package documented in this manual provides the \babel\ package with all
%    language-specific strings, settings and commands needed for writing German texts
%    (or German passages in texts).
%    Furthermore, the package assures that the appropriate hyphenation patterns are used
%    for these texts or text passages (see sec.~\ref{sec:patterns} for details).
%
%    Since German is a pluricentric language with differing standard varieties (in Austria,
%    Switzerland, and Germany), \babelde\ supports three varieties of Standard German.\footnote{%
%              Austria, Switzerland, and Germany are so-called \emph{full centers} of Standard German, as they developed
%              each their specific codex. German is also an official language in Liechtenstein and Luxembourg,
%              in parts of Italy (South Tyrol/Alte Adige), and a legally acknowledged minority language
%              in other regions in the world.
%              However, these \emph{half} and \emph{quarter centers} do not have their own codizes;
%              South Tyrol/Alte Adige employs Austrian standard, Liechtenstein Swiss standard, Luxembourg and Belgium
%              orient towards German standard (cf. \cite{vwb} for linguistic details).}
%    Furthermore, since the spelling and hyphenation rules of German (in all these standard varieties)
%    have been reformed in 1996 (and in subsequent years), the package provides support for two spelling
%    and hyphenation variants of each standard variety, viz.\ the deprecated 1901 spelling and the current
%    (`reformed') 1996 spelling.
%    
%    The following section provides some information on the history of the package, and in particular
%    on a major interface change as of version 2.99. If you have been a user of \babelde\ before
%    that version, you are advised to read this.
%    If you are new or started using \babelde\ later than that, and just interested how to use the package,
%    you can jump directly to section~\ref{sec:usage}.
%
%
%    \section{Caveats on Language Naming}\label{sec:langnaming}
%
%    \subsection{Language Names in \babelde: A Tangled Affair}\label{sec:tangled}
%
%    The origins of this package reach well beyond the mentioned spelling reform.\footnote{%
%              Support for pre-1996 German started as a re-implementation of the package
%              \file{german.sty} (v.\,2.5b), originally developed by Hubert Partl (cf.\,\cite{HP})
%              and later maintained by Bernd Raichle (cf.\,\cite{gerdoc}).
%              Support for current varieties of German (post-1996 orthography)
%              emerged as a re-implementation of Walter Schmidt's (1998, cf.\,\cite{schmidt}) 
%              companion package to \file{german.sty}, \file{ngerman.sty}.
%              The initial re-implementations for \babel\ were done by Johannes Braams, the original
%              author and then maintainer of \babel, in 1990 (for pre-1996 conventions)
%              and 1999 (for post-1996 conventions). In 2013, Jürgen Spitzmüller took over maintainership
%              for the then orphaned language support files that have been outsourced from \babel\ itself
%              to the independent package, \babelde.}
%    This has led to a rather unfortunate situation.
%    When the spelling reform happened, the terms \emph{german} and \emph{austrian}\footnote{%
%	    \emph{Austrian} is a rather clumsy and irritating shorthand for \emph{Austrian [Standard] German},
%           which does not only imply that there is a completely separate `Austrian' language, but also that
%           in Austria, (Austrian Standard) German is the only official language (whereas, according to the
%           Austrian constitution, there are seven more, the so-called `acknowledged minority languages'
%           [Burgenland] Croatian, Czech, Hungarian, Slovak, Slowenian, Romanes, and Austrian Sign Language).}
%    have already been used in \babel\ for a couple of years, but of course they adhered to the rules of pre-1996
%    spelling\slash hyphenation. Since these rules (both spelling and hyphenation) changed quite significantly
%    with the reform, post-1996 German orthography could not be supported with the existing language support files.
%    Adapting those to the reformed orthography was not an option, as this would have dropped support for the previous norms
%    (and hence existing or future documents that employ pre-1996 orthography).
%    It would also not have been socially acceptable since the spelling reform hit quite heavy resistance in the general
%    public (cf. \cite{johnson}), and many (\LaTeX\ users certainly included) assumed, and hoped, the new rules would be
%    withdrawn again rather sooner than later anyway.
%
%    Against the backdrop of this, post-1996 support had not been integrated into the existing language support files
%    for German and Austrian German, but provided separately in additional ones (technically in completely separated,
%    though collectively distributed packages) -- incidentally almost three years after the reformed orthography has
%    come into effect (albeit with a transition period of eight years).
%    These additional support files were named \emph{naustrian} and \emph{ngerman} in order to distinguish them from
%    the received ones (with the \emph{n} obviously expanding to `new', referring to the then common label,
%    \emph{neue Rechtschreibung} `new orthography').
%    When support for the Swiss standard variety was added in 2013, the `new orthography' was not so new anymore
%    and widely accepted. Nonetheless, the naming convention was not touched and adopted for the new varieties,
%    \Lopt{swissgerman} (pre-1996) and \Lopt{nswissgerman} (post-1996). 
%
%    Fast forward even more, thirty years after the reformed rules have been implemented,
%    the 1996 orthography and the heated debate it caused have long settled,
%    the (no longer really) `new' orthography is the common one in all German-writing countries.
%    Pre-1996 orthography is only employed by a minority of writers as the main norm, but of course it
%    is still needed for texts that have been written before the reform, or -- more commonly -- as
%    a secondary variety if you quote from such older texts.
%
%    So, to be sure, in our days, most people expect to get current (that is, post-1996) standards
%    when selecting \Lopt{german} in \babel. Some arguably are not even aware that there have been
%    older orthographic standards.
%    Yet with \babel, one still needed to select \Lopt{ngerman}, \Lopt{naustrian}, or \Lopt{nswissgerman}
%    to get contemporary orthographic conventions and hyphenation rules in the year 2025!
%    The terms you would intuitively use, on the other hand, loaded patterns and captions that are not
%    what many users would expect, namely those adhering to pre-1996 norms. 
%    
%    Why hasn't this been changed once the 1996 orthography has settled? The main reason is \emph{backwards compatibility}.
%    A simple semantic switch (with \Lopt{german} then suddenly meaning post-1996 orthography) would break with a central
%    promise of \LaTeX: \LaTeX\ does not change the output of existing documents behind the back of their authors!
%
%    While this is a very good principle, sometimes breaking it might be warranted, since keeping things
%    as they are causes more harm than it prevents from. And this has arguably become the case with the language
%    names of \babelde: More and more people reported that they are irritated by the fact that \Lopt{german} does not mean what
%    they expect (namely, German according to current standards). It has been assumed that many even erroneuosly loaded pre-1996 patterns
%    without noticing (and getting wrong hyphenations).
%    Given all that, we have been urged to do the compatibility-breaking change, and at some point,
%    we have finally been convinced to do it -- but only since we found some strategies to do it in a way that will
%    affect as less users as possible (although it will still definitely affect some).
%    The next section will elaborate on the changes and strategies.
%
%    \subsection{The New Language Naming Convention}
%
%    With\newfeature{2.99} v.\,2.99 of this package, a new and more appropriate naming scheme is introduced.
%    As of v.\,3.0, we will also change the (default) semantics of \Lopt{german}.
%    All of these are major changes which might break backwards compatibility (but only the change of \Lopt{german}
%    will do it in a way that affects \emph{existing} documents as opposed to new documents sent to
%    users of older versions of \babelde).
%    The changes address several problems:
%    \begin{enumerate}
%	    \item Ultimately, the confusion of \Lopt{german} activating pre-1996 orthography shall be resolved.
%             From v.\,3.0 on, \Lopt{german} will load contemporary (post-1996) patterns for German Standard German\footnote{%
%                  This follows the received convention to imply \emph{German} Standard German for \Lopt{german}, but see
%                  section~\ref{sec:glottonyms} why this is not so straightforward.},
%             except for documents where we assume it really means pre-1996 orthography, that is, documents also loading
%             \Lopt{ngerman}, \Lopt{naustrian}, or \Lopt{nswissgerman}.
%
%             This will also have an effect on the internal language names, which are still defined in the file \file{language.dat}
%             in the received way (meaning |\l@german| continues to denote pre-1996 patterns, |\l@ngerman| post-1996 patterns by default).
%             If the semantics of \Lopt{german} is changed, |\l@german| also has to be redefined. Hence, a new name for pre-1996 German is introduced,
%             |\l@tgerman|, which will have a stable meaning independent of the naming convention, |\l@ngerman| continues to denote post-1996 patterns,
%             |\l@german| might denote one or the other, depending on the option discussed next.
%       \item To adjust this for specific documents, we introduce an option where you can select whether \Lopt{german}
%             should still always load pre-1996 patterns (this will remain to be the default before v.\,3.0),
%             always post-1996 patterns notwithstanding parallel usages of \Lopt{ngerman}, \Lopt{naustrian}, or \Lopt{nswissgerman},
%             or guess depending on whether these |n|-options are used or not (the default as of v.\,3.0).
%             See section~\ref{sec:glottonyms} for details.
%       \item While we are at it, we introduce more appropriate terms (language options) for the selection of language varieties and deprecate
%             some of the problematic ones together with the |n|-forms (but of course, those received options will
%             continue to work, although they might encourage you to switch in a warning once the new scheme has settled).
%       \item These new language options also use the newer and better `experimental' hyphenation patterns by default, whereas
%             the received options continue to use the less accurate legacy patterns by default (see sec.~\ref{sec:patterns}).
%             The option \Lopt{german} uses the newer patterns whenever it is configured to refer to post-1996 orthography,
%             legacy patterns otherwise.
%    \end{enumerate}
%    Having unpacked all this rather intricate background, we now turn to the actual usage of the package.
%    
%
%    \section{Enabling German Support}\label{sec:usage}
%    
%    In order to use the language support provided by \babelde, you need to load
%    the \babel\ package (via |\usepackage{babel}|) and pass one of the following language options
%    either directly to \babel\ (via |\usepackage[<options>]{babel}|) or to |\documentclass|
%    (the latter has the advantage that also other packages are informed of the option\footnote{%
%         Side note to package authors; \babelde\ inserts the respective legacy options to the class
%         options list if new options are used. So the new options should also work with most
%         packages that only rely on the received ones.}).
%    If you use multiple languages\slash varieties (including different regional or
%    orthographic varieties of German), the one passed last is treated by \babel\
%    as the main language of the document.
%
%    The behavior of some language varieties can be adjusted by language variety options.
%    All of these can be set via the macro \newfeature{2.99}|\germansetup|, which takes a
%    comma-separated list of options as its mandatory argument and is to be used in the
%    document preamble after \babel\ has been loaded (see sec.~\ref{sec:options}).
%    Some options alternatively might be passed as a \babel\ modifier, which might give
%    a more granular setting, since |\germansetup| applies to all varieties that support a
%    specific option, \babel\ modifiers only to the variety that is being modified.\footnote{\label{fn:mod}%
%           If languages are loaded via \babel\ option, modifiers are appended to the language name with a dot, e.\,g.
%           \Lopt{german-at.capsz}; if languages are loaded via \texttt{\textbackslash documentclass} options,
%           use additionally \babel\ options of the form \Lopt{modifiers.german-at=capsz}.}
%
%    The available language and language variety options are introduced in what follows.
%
%    \subsection{Austrian Standard German}\label{sec:austrian}
%
%    \emph{Austrian Standard German} refers to the norms current in Austria and South Tyrol/Alte Adige.
%    The available choices are:
%    \begin{itemize}
%       \setlength{\itemsep}{0pt}
%       \item \newfeature{2.99}\Lopt{german-at} or \Lopt{german-austria} if you want contemporary (post-1996) patterns
%       \item \Lopt{german-at-1901} or \Lopt{german-austria-1901} if you want pre-reform (pre-1996) patterns
%    \end{itemize}
%    Contemporary\newfeature{2.14} (post-1996) Austrian Standard German provides an additional feature that is enabled
%    via the language variety option (|\germansetup| or \babel\ modifier) \Lopt{capsz} and disabled via |\germansetup|
%    option \Lopt{capsz=false} or \babel\ modifier \Lopt{nocapsz}:
%    \begin{itemize}
%       \setlength{\itemsep}{0pt}
%       \item \Lopt{capsz}: |\MakeUppercase{ß}|, |\MakeUppercase{"s}| and the |"S| shorthand expand to the capital
%	           eszett letter rather than \graph{SS} (see sec.~\ref{sec:capsz} for details).
%       \item \Lopt{nocapsz} (=~default): |\MakeUppercase{ß}|, |\MakeUppercase{"s}| and the |"S| expand to
%	           \graph{SS}. Within |\germansetup|, use \Lopt{capsz=false} instead.
%    \end{itemize}
%    The received options \Lopt{austrian} and \Lopt{naustrian} still work (the latter also with the |capsz| option),
%    but you are discouraged to use them unless you share your document with co-authors who have an older
%    version of \babelde\ installed, or if you use a package that does not (yet) understand
%    the new options. Also note that these options use the legacy hyphenation patterns by default, whereas
%    the recommended options use the newer and better `experimental' patterns (see sec.~\ref{sec:patterns}).
%
%    \subsection{German Standard German}\label{sec:german}
%
%    \emph{German Standard German} refers to the norms current in Germany, Luxembourg, and
%    Belgium.
%    The available choices are:
%    \begin{itemize}
%       \setlength{\itemsep}{0pt}
%       \item \newfeature{2.99}\Lopt{german-de} or \Lopt{german-germany} if you want contemporary (post-1996) patterns
%       \item \Lopt{german-de-1901} or \Lopt{german-germany-1901} if you want pre-reform (pre-1996) patterns
%    \end{itemize}
%    Like\newfeature{2.14} Austrian Standard German, contemporary (post-1996) German Standard German optionally supports
%    the capital eszett letter. The feature is enabled via the language variety option (|\germansetup| or \babel\ modifier)
%    \Lopt{capsz} and disabled via \babel\ modifier \Lopt{nocapsz} or |\germansetup| option \Lopt{capsz=false}:
%    \begin{itemize}
%       \setlength{\itemsep}{0pt}
%       \item \Lopt{capsz}: |\MakeUppercase{ß}|, |\MakeUppercase{"s}| and the |"S| shorthand expand to the capital
%	           eszett letter rather than \graph{SS} (see sec.~\ref{sec:capsz} for details).
%       \item \Lopt{nocapsz} (=~default): |\MakeUppercase{ß}|, |\MakeUppercase{"s}| and the |"S| expand to
%	           \graph{SS}. Within |\germansetup|, use \Lopt{capsz=false} instead.
%    \end{itemize}
%    The received options \Lopt{german} and \Lopt{ngerman} still work (the latter also with the |capsz| option),
%    but you are discouraged to use them unless you share your document with co-authors who have an older
%    version of \babelde\ installed, or if you use a package that does not (yet) understand the new options.
%
%    While \Lopt{german} seems the obvious choice to typeset German, it is in many ways ambiguous due to its
%    terminological tradition in \babel\ (as well as in other packages such as \file{german.sty}) and due to
%    the fact that there are multiple parallel standards (see sec.\ref{sec:glottonyms}).
%    So it is always advisable to use a more precise option such as \Lopt{german-de}.
%
%    Also, unless |glottonyms=contemporary| or |glottonyms=auto| is set (see section~\ref{sec:glottonyms}),
%    \Lopt{german} will still load pre-reform (pre-1996) and legacy hyphenation patterns
%    (this will change as of \babelde\ v.\,3.0), \Lopt{ngerman} also uses the legacy hyphenation patterns
%    by default. The options recommended above, by contrast, use the newer and better `experimental'
%    patterns (see sec.~\ref{sec:patterns}).
%
%    \subsection{Swiss Standard German}\label{sec:swiss}
%
%    \emph{Swiss Standard German} refers to the norms current in Switzerland and Liechtenstein.
%    The available choices are:
%    \begin{itemize}
%       \setlength{\itemsep}{0pt}
%       \item \newfeature{2.99}\Lopt{german-ch} or \Lopt{german-switzerland} if you want contemporary (post-1996) patterns
%       \item \Lopt{german-ch-1901} or \Lopt{german-switzerland-1901} if you want pre-reform (pre-1996) patterns
%    \end{itemize}
%    Swiss\newfeature{2.10} Standard German (both pre-and post-1996) provides an additional feature that is enabled
%    via the language variety option (|\germansetup| or \babel\ modifier) \Lopt{toss}:
%    \begin{itemize}
%       \item \Lopt{toss}: the shorthands |"s| and |"z| will expand to \graph{ss} rather
%             than \graph{ß} (see sec.~\ref{sec:toss} for details).
%
%    \end{itemize}
%    The received options \Lopt{swissgerman} and \Lopt{nswissgerman} still work (also with the |toss| option),
%    but you are discouraged to use them unless you share your document with co-authors who have an older
%    version of \babelde\ installed, or if you use a package that does not (yet) understand
%    the new options. Also note that \Lopt{nswissgerman} uses the legacy hyphenation patterns by default, whereas
%    the recommended options use the newer and better `experimental' patterns (see sec.~\ref{sec:patterns}).
%
%    \subsection{Options}\label{sec:options}
%
%    The behavior of \babelde\ can be configured by a number of options. These are all set in the preamble via
%    the command |\germansetup{<options>}| which takes a comma-separated list of key-value options.
%    These are:
%\begin{itemize}
%  \setlength\itemsep{0pt}
%     \item \texttt{capsz=true\textbar false} determines whether capital \graph{ß} is output as a capital eszett
%           letter or as \graph{SS}. Only available for Austrian and German 1996 German.
%            See sec.~\ref{sec:capsz}. Default: |false|.
%     \item \texttt{gendermark=<symbol>} the symbol used for marking gender forms as entered via the
%           \babel\ shorthand |"x| (see sec.~\ref{sec:shorthands}). Default: |*|.
%     \item \texttt{glottonyms=auto\textbar contemporary\textbar legacy} determines how the language option \Lopt{german} is
%           interpreted (1901 or 1996 orthography). See sec.~\ref{sec:glottonyms}. Default: |legacy|.
%     \item \texttt{toss=true\textbar false} determines whether the shorthands |"s| and |"z| will expand to \graph{ss}
%            or than \graph{ß}. Only available for Swiss Standard German. See sec.~\ref{sec:toss}.
%            Default: |false|.
%     \item \texttt{hyphenrules=latest\textbar legacy\textbar <date>} determines which hyphenation patterns are used.
%            See sec.~\ref{sec:patterns}. Default: |legacy| for \Lopt{austrian}, \Lopt{german} with
%            1901 meaning (see sec.~\ref{sec:glottonyms}), \Lopt{swissgerman}, \Lopt{naustrian},
%            \Lopt{ngerman} and \Lopt{nswissgerman}, |latest| for all other language options.
%\end{itemize}
%
%    \section{Configuring the Meaning of \Lopt{german}}\label{sec:glottonyms}
%
%    In\newfeature{2.99} section~\ref{sec:langnaming}, we have elaborated on the intricate situation with how pre- and
%    post-1996 spelling variants have been traditionally named in \babelde. Meanwhile, \babelde\ has introduced
%    more appropriate names, but still the situation with the ambiguity of \Lopt{german} is challenging.\footnote{%
%              Arguable, this also applies to \Lopt{austrian} and \Lopt{swissgerman}, but these names are discouraged
%              anyway and will not change semantics.}
%
%    Since German is a pluricentric language (cf. \cite{clyne}), a label such as \Lopt{german} is of course inherently ambiguous
%    (does it mean Austrian, German, or Swiss Standard German? The answer arguably depends on where you are located\footnote{%
%        On a more global scale, it arguably also depends on politics and historical hegemonies.
%        Which variety a generic language name assumes as default is neither depending on the `origin' of the
%        language or whether the language name is associated with the name of a country (cf.\ \Lopt{english} which assumes
%        American, not British Standard English, as default), nor the number of speakers
%        (cf.\ \Lopt{spanish} which assumes Standard Spanish in Spain, not in Mexico, as default, or \Lopt{portuges} [sic!] which
%        assumes Standard Portuguese in Portugal, not in Brazil). Yet it is also not by coincidence.
%        The selection of a default (and this also accounts for norm authorities such as the ISO or the IETF) is mainly,
%        and inherently, political, ideological, and power-driven, notwithstanding the involved actors often stating that it is not.}).
%    Hence, it is better to use less ambiguous terms such as |german-de| or |german-germany|.
%
%    Having said this, we understand that an option |german| which produces sensible results is expected
%    in the context of \babel\ and its (often rather awkward) language option terminology.
%    And in this context, the traditional meaning of \Lopt{german} (referring to the pre-1996 German Standard German)
%    obviously causes irritation. Whichever national variety of German \babel\ users might expect when using \Lopt{german}, they
%    most probably would expect \emph{contemporary} standards -- at least if they are not already familiar with the received
%    \babelde\ terminology.
%
%    In order to mitigate this for users who employ the \Lopt{german} option rather than the more precise alternatives,
%    and considering both novice and experienced users of \babelde,
%    an option |glottonyms| is provided (\emph{glottonym} means `language name').
%    It has to be set via |\germansetup| and offers the following choices:
%    \begin{itemize}
%	   \item  |glottomyms=legacy|: \Lopt{german} always enables pre-1996 
%             spelling, as it has been traditionally the case in \babelde. It also uses the legacy hyphenation patterns.
%             Use this if you need to maintain 100\,\% backwards compatibility. This is also the current default.
%	   \item  |glottomyms=contemporary|: \Lopt{german} always enables post-1996
%             spelling, which breaks with traditional package conventions and might
%             break documents that use those. It also uses the `experimental' hyphenation patterns by default.
%             Use with care!
%	   \item  |glottomyms=auto|: \Lopt{german} \emph{as a rule} enables post-1996
%             spelling (and newer hyphenation patterns). However, as soon as \Lopt{ngerman}, \Lopt{naustrian} or
%             \Lopt{nswissgerman} are also used in the same document, we assume that \Lopt{german} is supposed to refer to the
%             pre-1996 variant instead and hence make \Lopt{german} enable pre-1996 German Standard German (and legacy patterns).
%             This should handle gracefully most contemporary uses of \Lopt{german}, although it
%             will break documents using only \Lopt{german} with the traditional meaning
%             (for which you should use |glottomyms=legacy|).
%             This choice will be the new default as of \babelde\ v.\,3.0.
%    \end{itemize}
%    Note, however, that the semantics is only changed here for \babelde\ itself.
%    If you use a third-party package which relies on the |legacy| semantics, you need to stick
%    with this and report to the maintainer of that package.
%
%\iffalse
%    %enable with 3.0
%    If you want to share a document that employs \Lopt{german-de-1901} spelling \emph{exclusively}
%    with a co-author who only has an older version of \babelde\ available, we suggest to
%    load the options |ngerman,german| and use \Lopt{german} in the traditional way within the
%    document.
%\fi
%
%   \section{Hyphenation Patterns}\label{sec:patterns}
%
%   For German, different hyphenation patterns are available. Which of these a given document employs
%   does not only depend on the varieties it uses, but also on the \TeX\ engine and on the language options you employ.
%   For most varieties and options, there are multiple options to select from. This is elaborated in what follows.
%
%   Hyphenation patterns for pre- and post-1996 German orthography have been available with \TeX\ distributions
%   for a long time (currently, these are shipped in form of the \texttt{dehypht} [=~traditional] and
%   \texttt{dehyphn} [=~new] files).
%   These established patterns, however, have many flaws: they are hard to maintain and improve since the
%   sources are not available and not much is known about their construction, since they do not work well
%   with loans, some compounds, and technical terms and often do not hyphenate where they could, and -- most gravely --
%   since they might produce wrong hyphenations (e.g., \emph{Mor-dopfer} instead of \emph{Mord-opfer}).
%   The patterns for post-1996 orthography are even worse: they have only been \emph{manually} adapted to the new rules
%   and intended to be just some intermediate solution right from the start (cf. \cite{schmidt}).
%
%   Therefore, a group of experienced germanophone \LaTeX\ users (including the author of the legacy \texttt{dehyphn} patterns)
%   took on the challenge and 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 established patterns, the new ones undergo constant improvement.
%   The price for this is that hyphenation and thus the typeset document is subject to change with,
%   and only due to, pattern updates.
%   However, the new patterns are around and used since 2008, they have largely stabilized and are really no
%   longer `experimental'.
%
%   Modern engines (i.\,e., \texttt{xetex} and \texttt{luatex}) who require utf8-encoded patterns have already embraced
%   those new patterns long ago, i.\,e., they are activated on these engines by default (cf. \cite{hyph-utf8}).
%   The classic \TeX\ engines (\texttt{tex}\slash\texttt{pdftex}) have been more reluctant and continue to use the old
%   patterns by default.
%   The reason for this are the \TeX\ quality standards already mentioned in sec.~\ref{sec:tangled}:
%   refrain, if ever possible, from changing the output of user's documents in the wake of software updates.
%   However, even there, there was an exception: with pre-1996 Swiss Standard German, the classic engines
%   use the `experimental' patterns by default since when Swiss German was introduced, the `experimental'
%   patterns have already been available.
%
%   In \babelde, we take the introduction of the new language options in v.\,2.99 as an opportunity to default
%   to the latest `experimental' patterns with these options. For \Lopt{german}, with \Lopt{glottonyms=legacy}
%   or \Lopt{glottonyms=auto} and the use of an |n-|option (i.\,e., if it refers to pre-1996 orthography),
%   the established (legacy) patterns will continue to be used. With the newer meaning (\Lopt{glottonyms=contemporary}
%   or \Lopt{glottonyms=auto} without the use of an |n-|option), \babelde\ also defaults to the latest
%   `experimental' patterns.  The other legacy options (\Lopt{austrian}, \Lopt{naustrian},
%   \Lopt{ngerman}, and \Lopt{nswissgerman}) will continue to default to the established (legacy) patterns.
%   This way, we assure existing documents will not change their hyphenation behind your back.
%
%   In all these cases (except for pre-1996 Swiss Standard German where no `legacy' patterns exist), however,
%   you can opt-in to a different setting.
%   If you want to use the experimental patterns also with the legacy language options, use
%\begin{verbatim}
%    \germansetup{hyphenrules=latest}
%\end{verbatim}
%   in the document preamble after \babel\ has been loaded.
%   This will activate the experimental hyphenation patterns in their most recent version for all used varieties of German.
%   Reversely,
%\begin{verbatim}
%    \germansetup{hyphenrules=legacy}
%\end{verbatim}
%   will switch to the established patterns for all used varieties of German.
%
%   The \textsf{dehyph-exptl} package also allows to load patterns of a given (fixed) date instead of the latest ones,
%   e.g. |2024-02-28|. Therewith, you can prevent future changes in hyphenation due to package updates.
%   The feature is also supported by \babelde: Simply pass the date to |hyphenrules| (e.\,g., |hyphenrules=2024-02-28|).
%   Of course, you need to assure patterns of this date exist in your tree. Cf. \cite{exptl} for details, also for ways
%   to set specific patterns to specific varieties of German only.
%
%    \section{Shorthands and Convenience Macros}\label{sec:shorthands}
%
%    For all varieties of German, the character |"| is made active
%    in order to provide some shorthand macros.
%
%    Some of these shorthands address peculiarities of pre-1996 German spelling with which you do not need to bother
%    if you adhere to contemporary orthography:
%    \begin{enumerate}
%    \item the so-called \emph{Dreikonsonanten-Regel} (`three consonant rule')
%          which required specific handling of specific compounds in hyphenation\footnote{\label{fn:threecons}%
%             The three consonant rule (cf. \cite[R\,204]{duden91}) prescribed that one of three identical consonants had to be omitted
%             if a vowel followed the three consonants (i.\,e., you wrote \emph{Schiffahrt}, not \emph{Schifffahrt},
%             \emph{schnellebig}, not \emph{schnelllebig}, \emph{wetturnen}, not \emph{wettturnen}).
%             If the word was hyphenated at this position, however, the third consonant needed to reappear (\emph{Schiff-fahrt},
%             \emph{schnell-lebig}, \emph{wett-turnen}); the shorthands |"f|, |"l|, |"t| etc. account for that.
%             With the 1996 reform, the rule has been taken out of force (cf. \cite[R\,136]{duden96}).
%             Now, all consonants are always written (some lexicalized exceptions  are \emph{dennoch} and \emph{Mittag},
%             but these get no additional consonant on hyphenation either: \emph{den-noch}, \emph{Mit-tag}).
%             Note also that \graph{s} (as in \emph{Kongresssaal}, if \graph{ss} is used as an alternative to \graph{\ss} or in Swiss writing)
%             has always  been excluded from this rule (cf. \cite[R\,204]{duden91}), which is why no shorthand for that case is needed.}, and
%    \item the hyphenation of the digraph\footnote{\label{fn:digraph}%
%             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{ck} as \graph{k-k} (e.\,g., \emph{Bäcker}, \emph{Bäk-ker}), which has been dropped with
%          the reform in favor of shifting the whole digraph to the next line (\emph{Bä-cker}).
%    \end{enumerate}
%    Other shorthands are provided for frequently used special characters as well as for better control of hyphenation,
%    line breaks, and ligatures, and are useful for all varieties of German.
%
%    Table~\ref{tab:german-quote} provides an overview of the shorthands
%    that are provided by \textsf{babel-german} for all its variants.
%    Table~\ref{tab:more-quote} lists some \babel\ macros for quotation marks
%    that might be used as an alternative to the quotation mark shorthands listed above.

%
%    \subsection{Capital Eszett Letter}\label{sec:capsz}
%
%    In\newfeature{2.14} 2008, a capital variant of the letter \graph{\ss} has been included to the Unicode standard
%    (U+1E9E), and in 2017, the capital eszett letter has been acknowledged in German orthography as a valid alternative
%    to \graph{SS} in uppercase writing of \graph{\ss}. The letter differs from its miniscule counterpart in that it is
%    usually wider to match the form of uppercase letters.
%
%    If you want to use this letter, you can do so by using the variety option \Lopt{capsz}, which is supported
%    for the contemporary (post-1996) Austrian (cf. sec.~\ref{sec:austrian}) and German (cf. sec.~\ref{sec:german})
%    varieties. If you pass the option to |germansetup|, i.\,e.,
%\begin{verbatim}
%    \germansetup{capsz}
%\end{verbatim}
%    it will apply to both those varieties. If you want a more
%    granular setting, use a \babel\ modifier instead (see sec.~\ref{sec:usage}).
%    As the eszett letter is not common in Swiss German writing in general, the option is not supported there.
%    Similarly, the pre-1996 varieties do not support the letter either.
%
%    The option causes both |\MakeUppercase| and the |"S| shorthand (but not |"Z|) to use the capital eszett letter.
%    Note that this requires a font which actually contains the glyph (otherwise, you still get \graph{SS})
%    and \LaTeX\ kernel 2023/06 at least.
%
%    Note\newfeature{2.15} that you can also set the casing via |\babelprovide[casing=eszett]{<lang>}|.
%    This is adhered to. If you want to disable such a global setting, you can do so by means of the
%    |\germansetup| option \Lopt{capsz=false} or \babel\ modifier \Lopt{nocapsz}.
%
%   \subsection{Handling of \texttt{"s} and \texttt{"z} in Swiss German}\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} `penance'). 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{See footnote~\ref{fn:digraph} for what this means.}
%   \graph{ss} and \graph{sz} rather than to \graph{\ss}. This is not the default behavior with \Lopt{german-ch} and
%   \Lopt{german-ch-1901} 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 |\germansetup| option or the \babel\ modifier \Lopt{toss}
%         (read: `to \graph{ss}') with \Lopt{german-ch}, \Lopt{german-ch-1901} or its aliases (see sec.~\ref{sec:usage}).
%         The former will apply to all Swiss German varieties, the latter only to the language option that is being modified.
%
%   \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}
%   All these changes result in the following deviant behavior of two shorthands:\smallskip
%
%     \begin{tabular}{l>{\raggedright}p{.9\textwidth}}
%      |"s|	& 	expands to digraph \graph{ss}             \tabularnewline
%      |"z|	& 	expands to digraph \graph{sz}             \tabularnewline
%     \end{tabular}\smallskip
%
%    \noindent One further note related to the use of \graph{ss} in pre-1996 Swiss Standard German. As opposed to other consonantial letters,
%    the \graph{s} is excluded from the three consonant rule (\emph{Dreikonsonantenregel}) of traditional (i.\,e., 1901) German
%    spelling (cf.\ footnote~\ref{fn:threecons}). This is why we don't provide a shorthand for the \graph{sss} case.
%
%
%   \section{Captions, Extras, and Dates}
%
%   The caption strings (such as ``figure'') are defined in the macros |\captions<language>|, where |<language>|
%   resolves to the current language option. With the new names, however, captions macros of traditional names
%   are still defined and inherited. So redefining |\captionsngerman| and |\captionsgerman-de| will have the
%   same effect with the option \Lopt{german-de}. Vice versa, however, redefining |\captionsgerman-de| will
%   \emph{not} have any effect if the alias \Lopt{german-germany} is used.
%   The same applies to |\extras<language>| and |\noextras<language>| which hold extra language settings.
%
%   The recommended way to change or add caption strings is the \babel\ macro
%\begin{verbatim}
%     \setlocalecaption{<language-name>}{<caption-name>}{<string>}
%\end{verbatim}
%   where |<language-name>| is the respective language option, |<caption-name>| the respective
%   caption macro (without preceding backslash and trailing |name|), and |<string>| the string to which
%   it should expand. E.g.,
%\begin{verbatim}
%     \setlocalecaption{german-de}{ref}{Bibliografie}
%\end{verbatim}
%   The predefined caption names are (the macros have an appended |name|):
%\begin{itemize}
%\setlength\itemsep{0pt}
%   \item \texttt{preface}: \emph{Vorwort}
%   \item \texttt{ref}: \emph{Literatur}
%   \item \texttt{abstract}: \emph{Zusammenfassung}
%   \item \texttt{bib}: \emph{Literaturverzeichnis}
%   \item \texttt{chapter}: \emph{Kapitel}
%   \item \texttt{appendix}: \emph{Anhang}
%   \item \texttt{contents}: \emph{Inhaltsverzeichnis}
%   \item \texttt{listfigure}: \emph{Abbildungsverzeichnis}
%   \item \texttt{listtable}: \emph{Tabellenverzeichnis}
%   \item \texttt{index}: \emph{Index}
%   \item \texttt{figure}: \emph{Abbildung}
%   \item \texttt{table}: \emph{Tabelle}
%   \item \texttt{part}: \emph{Teil}
%   \item \texttt{encl}: \emph{Anlage(n)} (de) or \emph{Beilage(n)} (ch and at)
%   \item \texttt{cc}: \emph{Verteiler}
%   \item \texttt{headto}: \emph{An}
%   \item \texttt{page}: \emph{Seite}
%   \item \texttt{see}: \emph{siehe}
%   \item \texttt{also}: \emph{siehe auch}
%   \item \texttt{proof}: \emph{Beweis}
%   \item \texttt{glossary}: \emph{Glossar}
%\end{itemize}
%   If you want to change captions of all German varieties at once, you can use the |<language-name>| |allgerman|
%   with the |\setlocalecaption| macro (|\captionsallgerman| is inherited by all varieties). To redefine all
%   Austrian or Swiss varieties, respectively, use |allatgerman| and |allchgerman|.
%
%   As opposed to this, |\extras<language>|, |\noextras<language>| and |\date<language>| are appended
%   by |\addto|.
%   Note, however, that the extension via |\addto| is not straightforward in the case of
%   language options containing hyphens (such as |german-de|) since the hyphen has a different catcode
%   normally (e.g., in document preambles) and hence terminates command parsing.
%   So you either need to resort to the legacy names (such as |ngerman|), control command parsing via 
%\begin{verbatim}
%     \expandafter\addto\csname <macro>\endcsname{<code>}
%\end{verbatim}
%   or use the \babelde\ helper macro |\addtocs{<macro>}{<code>}|, which does the latter under the hood,
%   taking as first argument the macro name without backslash. E.g.,
%\begin{verbatim}
%     \addtocs{extrasgerman-de}{\bbl@nonfrenchspacing}
%\end{verbatim}
%   Packages that want to change extras and noextras of all German varieties at once might append code to the internal
%   macros |\@extrasgerman| and |\@noextrasgerman| that are inherited by all varieties.
%
%   For date redefinitions, packages should redefine the internal macros |\date@german@at|, |\date@german@ch|,
%   and |\date@german@de| that hold the definitions for the respective regions and are being inherited in the
%   respective varieties.

%
%    In order to be able to define the function of |"|, we first define a

%  \begin{macro}{\dq}
%    We save the original double quotation mark character in |\dq| to keep
