%  \section{The Welsh language}
%
%    The file \file{\filename}\footnote{The file described in this
%    section has version number \fileversion\ and was last revised on
%    \filedate.}  defines all the language definition macros for the
%    Welsh language as well as for the <Dialect> version of this
%    language.
%
%    For this language currently no special definitions are needed or
%    available.
%
% \StopEventually{}
%
%    The macro |\ldf@init| takes care of preventing that this file is
%    loaded more than once, checking the category code of the
%    \texttt{@} sign, etc.
%    \begin{macrocode}
%<*code>
\LdfInit{welsh}{captionswelsh}
%    \end{macrocode}
%
%    When this file is read as an option, i.e. by the |\usepackage|
%    command, \texttt{welsh} could be an `unknown' language in
%    which case we have to make it known.  So we check for the
%    existence of |\l@welsh| to see whether we have to do
%    something here.
%
%    \begin{macrocode}
\ifx\undefined\l@welsh
  \@nopatterns{welsh}
  \adddialect\l@welsh0\fi
%    \end{macrocode}
%    The next step consists of defining commands to switch to (and
%    from) the Welsh language.
%
%  \begin{macro}{\welshhyphenmins}
%    This macro is used to store the correct values of the hyphenation
%    parameters |\lefthyphenmin| and |\righthyphenmin|.
% \changes{welsh-1.0c}{2000/09/22}{Now use \cs{providehyphenmins} to
%    provide a default value}
%    \begin{macrocode}
\providehyphenmins{\CurrentOption}{\tw@\thr@@}
%    \end{macrocode}
%  \end{macro}
%
% \begin{macro}{\captionswelsh}
%    The macro |\captionswelsh| defines all strings used in the
%    four standard documentclasses provided with \LaTeX.
% \changes{welsh-1.0c}{2000/09/20}{Added \cs{glossaryname}}

  }
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\datewelsh}
%    The macro |\datewelsh| redefines the command |\today| to
%    produce welsh dates.
% \changes{welsh-1.0b}{1997/10/01}{Use \cs{edef} to define
%    \cs{today} to save memory}
% \changes{welsh-1.0b}{1998/03/28}{use \cs{def} instead of
%    \cs{edef}}
%    \begin{macrocode}

  \space\number\year}}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\extraswelsh}
% \begin{macro}{\noextraswelsh}
%    The macro |\extraswelsh| will perform all the extra
%    definitions needed for the welsh language. The macro
%    |\noextraswelsh| is used to cancel the actions of
%    |\extraswelsh|.  For the moment these macros are empty but
%    they are defined for compatibility with the other
%    language definition files.
%
%    \begin{macrocode}
\addto\extraswelsh{}
\addto\noextraswelsh{}
%    \end{macrocode}
% \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.
%    \begin{macrocode}
