%  \section{The Upper Sorbian language}
%
%    The file \file{\filename}\footnote{The file described in this
%    section has version number \fileversion\ and was last revised on
%    \filedate.  It was written by Eduard Werner
%    (\texttt{edi@kaihh.hanse.de}).}  It defines all the
%    language-specific macros for Upper Sorbian.
%
% \StopEventually{}
%
%    The macro |\LdfInit| takes care of preventing that this file is
%    loaded more than once, checking the category code of the
%    \texttt{@} sign, etc.
% \changes{usorbian-1.0e}{1996/11/03}{Now use \cs{LdfInit} to perform
%    initial checks} 
%    \begin{macrocode}
%<*code>
\LdfInit{usorbian}\captionsusorbian
%    \end{macrocode}
%
%    When this file is read as an option, i.e. by the |\usepackage|
%    command, \texttt{usorbian} will be an `unknown' languagein which
%    case we have to make it known. So we check for the existence of
%    |\l@usorbian| to see whether we have to do something here.
%
%    \begin{macrocode}
\ifx\l@usorbian\@undefined
    \@nopatterns{Usorbian}
    \adddialect\l@usorbian0\fi
%    \end{macrocode}
%
%    The next step consists of defining commands to switch to (and
%    from) the Upper Sorbian language.
%
% \begin{macro}{\captionsusorbian}
%    The macro |\captionsusorbian| defines all strings used in the four
%    standard documentclasses provided with \LaTeX.
% \changes{usorbian-0.1c}{1994/11/27}{Removed two typos (Kapitel and
%    Dodatki)}
% \changes{usorbian-1.0b}{1995/07/04}{Added \cs{proofname} for
%    AMS-\LaTeX}
%    \begin{macrocode}
\addto\captionsusorbian{%
  \def\prefacename{Zawod}%
  \def\refname{Referency}%
  \def\abstractname{Abstrakt}%
  \def\bibname{Literatura}%
  \def\chaptername{Kapitl}%
  \def\appendixname{Dodawki}%
  \def\contentsname{Wobsah}%
  \def\listfigurename{Zapis wobrazow}%

  }%
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\newdateusorbian}
%    The macro |\newdateusorbian| redefines the command |\today| to
%    produce Upper Sorbian dates.
%    \begin{macrocode}
\def\newdateusorbian{%
\def\today{\number\day.~\ifcase\month\or
januara\or februara\or m\v erca\or apryla\or meje\or junija\or
  julija\or awgusta\or septembra\or oktobra\or
  nowembra\or decembra\fi
    \space \number\year}}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\olddateusorbian}
%    The macro |\olddateusorbian| redefines the command |\today| to
%    produce old-style Upper Sorbian dates.
%    \begin{macrocode}
\def\olddateusorbian{%
\def\today{\number\day.~\ifcase\month\or
  wulkeho r\'o\v zka\or ma\l eho r\'o\v zka\or nal\v etnika\or
  jutrownika\or r\'o\v zownika\or  sma\v znika\or pra\v znika\or
  \v znjenca\or po\v znjenca\or winowca\or nazymnika\or
  hodownika\fi \space \number\year}}
%    \end{macrocode}
% \end{macro}
%
%    The default will be the new-style dates.
%    \begin{macrocode}
\let\dateusorbian\newdateusorbian
%    \end{macrocode}
%
% \begin{macro}{\extrasusorbian}
%    The macro |\extrasusorbian| will perform all the extra
%    definitions needed for the Upper Sorbian language. It's pirated
%    from |germanb.sty|.  The macro |\noextrasusorbian| is used to
%    cancel the actions of |\extrasusorbian|.
%
%    Because for Upper Sorbian (as well as for Dutch) the \texttt{"}
%    character is made active. This is done once, later on its
%    definition may vary.
%    \begin{macrocode}
\initiate@active@char{"}
\addto\extrasusorbian{\languageshorthands{usorbian}}
\addto\extrasusorbian{\bbl@activate{"}}
%\addto\noextrasusorbian{\bbl@deactivate{"}}
%    \end{macrocode}
%
%    In order for \TeX\ to be able to hyphenate German Upper Sorbian
%    words which contain `\ss' we have to give the character a nonzero
%    |\lccode| (see Appendix H, the \TeX book).
%    \begin{macrocode}
\addto\extrasusorbian{\babel@savevariable{\lccode`\^^Y}%
  \lccode`\^^Y`\^^Y}
%    \end{macrocode}
%    The umlaut accent macro |\"| is changed to lower the umlaut dots.
%    The redefinition is done with the help of |\umlautlow|.
%    \begin{macrocode}
\addto\extrasusorbian{\babel@save\"\umlautlow}
\addto\noextrasusorbian{\umlauthigh}
%    \end{macrocode}
%    The Upper Sorbian hyphenation patterns can be used with
%    |\lefthyphenmin| and |\righthyphenmin| set to~2.
%    \begin{macrocode}
\def\usorbianhyphenmins{\tw@\tw@}
%    \end{macrocode}
% \end{macro}
%
% \changes{usorbian-1.0a}{1995/05/27}{Removed stuff that has been
%    moved to \file{babel.def}}
%
%  \begin{macro}{\dq}
%    We save the original double quote character in |\dq| to keep it
%    available, the math accent |\"| can now be typed as |"|.  Also we
%    store the original meaning of the command |\"| for future use.
%    \begin{macrocode}
\begingroup \catcode`\"12
\def\x{\endgroup
  \def\@SS{\mathchar"7019 }
  \def\dq{"}}
\x
%    \end{macrocode}
% \end{macro}
%
%    Now we can define the doublequote macros: the umlauts,
%    \begin{macrocode}
\declare@shorthand{usorbian}{"a}{\textormath{\"{a}}{\ddot a}}
\declare@shorthand{usorbian}{"o}{\textormath{\"{o}}{\ddot o}}

\declare@shorthand{usorbian}{"i}{\textormath{\"{\i}}{\ddot\imath}}
\declare@shorthand{usorbian}{"I}{\textormath{\"{I}}{\ddot I}}

%    \begin{macrocode}
\declare@shorthand{usorbian}{"s}{\textormath{\ss{}}{\@SS{}}}
\declare@shorthand{usorbian}{"S}{SS}

%    german and french quotes,
%    \begin{macrocode}

%    \end{macrocode}
%    discretionary commands
% \changes{usorbian-1.0c}{1996/01/24}{Now use \cs{bbl@disc}}

\declare@shorthand{usorbian}{"t}{\textormath{\bbl@disc t{tt}}{t}}
\declare@shorthand{usorbian}{"T}{\textormath{\bbl@disc T{TT}}{T}}
%    \end{macrocode}
%    and some additional commands:
%    \begin{macrocode}
\declare@shorthand{usorbian}{"-}{\penalty\@M\-\allowhyphens}
\declare@shorthand{usorbian}{"|}{%
  \textormath{\penalty\@M\discretionary{-}{}{\kern.03em}%
              \allowhyphens}{}}
\declare@shorthand{usorbian}{""}{\hskip\z@skip}
%    \end{macrocode}
%
%  \begin{macro}{\mdqon}
%  \begin{macro}{\mdqoff}
%  \begin{macro}{\ck}
%    All that's left to do now is to  define a couple of commands
%    for reasons of compatibility with \file{german.sty}.
%    \begin{macrocode}
\def\mdqon{\bbl@activate{"}}
\def\mdqoff{\bbl@deactivate{"}}
\def\ck{\allowhyphens\discretionary{k-}{k}{ck}\allowhyphens}
%    \end{macrocode}
%  \end{macro}
%  \end{macro}
%  \end{macro}
%
%    The macro |\ldf@finish| takes care of looking for a
%    configuration file, setting the main language to be switched on
%    at |\begin{document}| and resetting the category code of
%    \texttt{@} to its original value.
% \changes{usorbian-1.0e}{1996/11/03}{Now use \cs{ldf@finish} to wrap
