%  \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}
% \changes{usorbian-1.0j}{2007/10/19}{This file can be loaded under
%    more than one name.}
%    \begin{macrocode}
%<*code>
\LdfInit\CurrentOption{date\CurrentOption}
%    \end{macrocode}
%
%    When this file is read as an option, i.e. by the |\usepackage|
%    command, \texttt{usorbian} will be an `unknown' language, in 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.
% \changes{usorbian-1.0j}{2007/10/19}{Check for the option
%    lowersorbian}
%    As
%    \babel\ also knwos the option \Lopt{uppersorbian} we have to
%    check that as well.
%
%    \begin{macrocode}
\ifx\l@uppersorbian\@undefined
  \ifx\l@usorbian\@undefined
    \@nopatterns{usorbian}
    \adddialect\l@usorbian\z@
    \let\l@uppersorbian\l@usorbian

    \let\l@uppersorbian\l@usorbian
  \fi
\else
  \let\l@usorbian\l@uppersorbian
\fi
%    \end{macrocode}
%
%    The next step consists of defining commands to switch to (and
%    from) the Upper Sorbian language.
%
% \begin{macro}{\captionsusorbian}

%    The macro |\extrasusorbian| will perform all the extra

%
%    In order for \TeX\ to be able to hyphenate German Upper Sorbian
