%  \section{The Czech language}
%
%    The file \file{\filename}\footnote{The file described in this
%    section has version number \fileversion\ and was last revised on
%    \filedate.  Contributions were made by Milos Lokajicek ({\tt
%    LOKAJICK@CERNVM}).}  defines all the language-specific macros for
%    the Czech language.
%
%    For this language |\frenhspacing| is set and two macros |\q| and
%    |\w| for easy access to two accents are defined.
%
%    The command |\q| is used with the letters ({\tt t}, {\tt d}, {\tt
%    l}, and {\tt L}) and adds a {\tt'} to them to simulate a `hook'
%    that should be there.  The result looks like
%    t\kern-2pt\char'47. The command |\w| is used to put the accent
%    that appears in \aa ngstr\o m over the letters {\tt u} and {\tt
%    U}.
%
% \StopEventually{}
%
%    As this file needs to be read only once, we check whether it was
%    read before. If it was, the command |\captionsczech| is already
%    defined, so we can stop processing. If this command is undefined
%    we proceed with the various definitions and first show the
%    current version of this file.
%
% \changes{czech-1.0a}{15 july 91}{Added reset of catcode of @ before
%    {\tt\bsl endinput}.}
% \changes{czech-1.0b}{27 okt 91}{Removed use of {\tt\bsl
%    @ifundefined}}
%    \begin{macrocode}
\ifx\undefined\captionsczech
\else
  \selectlanguage{czech}
  \expandafter\endinput
\fi
%    \end{macrocode}
%
%  \begin{macro}{\atcatcode}
%    This file, \file{czech.sty}, may have been read while \TeX\ is in
%    the middle of processing a document, so we have to make sure the
%    category code of {\tt @} is `letter' while this file is being
%    read.  We save the category code of the @-sign in |\atcatcode|
%    and make it `letter'. Later the category code can be restored to
%    whatever it was before.
%
% \changes{czech-1.0a}{15 july 91}{Modified handling of catcode of @
%    again.}
% \changes{czech-1.0b}{27 okt 91}{Removed use of {\tt\bsl
%    makeatletter} and hence the need to load {\tt latexhax.com}}
%    \begin{macrocode}
\chardef\atcatcode=\catcode`\@
\catcode`\@=11\relax
%    \end{macrocode}
% \end{macro}
%
%    Now we determine whether the the common macros from the file
%    \file{babel.def} need to be read. We can be in one of two
%    situations: either another language option has been read earlier
%    on, in which case that other option has already read
%    \file{babel.def}, or {\tt czech} is the first language option to
%    be processed. In that case we need to read \file{babel.def} right
%    here before we continue.
%
% \changes{czech-1.1}{15 feb 92}{Added {\tt\bsl relax} after the
%    argument of {\tt\bsl input}}
%    \begin{macrocode}
\ifx\undefined\babel@core@loaded\input babel.def\relax\fi
%    \end{macrocode}
%
%    Tell the \LaTeX\ system who we are and write an entry on the
%    transcript.
%    \begin{macrocode}
\ProvidesFile{czech.sty}[1994/06/26 v1.3d
         Czech support from the babel system]
%    \end{macrocode}
%
%    Another check that has to be made, is if another language
%    specific file has been read already. In that case its definitions
%    have been activated. This might interfere with definitions this
%    file tries to make. Therefore we make sure that we cancel any
%    special definitions. This can be done by checking the existence
%    of the macro |\originalTeX|. If it exists we simply execute it,
%    otherwise it is |\let| to |\empty|.
% \changes{czech-1.0a}{15 july 91}{Added {\tt\bsl let\bsl originalTeX%
%    \bsl relax} to test for existence}
% \changes{czech-1.1}{15 feb 92}%
%        {{\tt\bsl originalTeX} should be expandable, {\tt\bsl let} it
%         to {\tt\bsl empty}}
%    \begin{macrocode}
\ifx\undefined\originalTeX \let\originalTeX\empty \else\originalTeX\fi
%    \end{macrocode}
%
%    When this file is read as an option, i.e. by the |\usepackage|
%    command, {\tt czech} will be an `unknown' language in which case
%    we have to make it known. So we check for the existence of
%    |\l@czech| to see whether we have to do something here.
%
% \changes{czech-1.0b}{27 okt 91}{Removed use of {\tt\bsl
%    @ifundefined}}
% \changes{czech-1.1}{15 feb 92}{Added a warning when no hyphenation
%    patterns were loaded.}
% \changes{czech-1.3d}{1994/06/26}{Now use \cs{@nopatterns} to produce
%    the warning}
%    \begin{macrocode}
\ifx\undefined\l@czech
    \@nopatterns{Czech}
    \adddialect\l@czech0\fi
%    \end{macrocode}
%
%    The next step consists of defining commands to switch to (and
%    from) the Czech language.
%
% \begin{macro}{\captionsczech}
%    The macro |\captionsczech| defines all strings used in the four
%    standard documentlasses provided with \LaTeX.
% \changes{czech-1.1}{15 feb 92}{Added {\tt\bsl seename}, {\tt\bsl
%    alsoname} and {\tt\bsl prefacename}}
%    \begin{macrocode}

  \def\pagename{Strana}%
  \def\seename{viz}%
  \def\alsoname{viz tek\'e}}%
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\dateczech}
%    The macro |\dateczech| redefines the command |\today| to produce
%    Czech dates.
%    \begin{macrocode}
\def\dateczech{%
\def\today{\number\day.~\ifcase\month\or
  ledna\or \'unora\or b\v{r}ezna\or dubna\or kv\v{e}tna\or \v{c}ervna\or

  listopadu\or prosince\fi
  \space \number\year}}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\extrasczech}
% \begin{macro}{\noextrasczech}
%    The macro |\extrasczech| will perform all the extra definitions
%    needed for the Czech language. The macro |\noextrasczech| is used
%    to cancel the actions of |\extrasczech|.  This means saving the
%    meaning of two one-letter control sequences before defining them.
%
% \changes{czech-1.1a}{07/07/92}{Removed typo from, `q was restored
%    twice, once too many.}
%    \begin{macrocode}
\addto\extrasczech{\babel@save\q\let\q\czech@q}
\addto\extrasczech{\babel@save\w\let\w\czech@w}
%    \end{macrocode}
%    For Czech texts |\frenchspacing| should be in effect. We make
%    sure this is the case and reset it if necessary.
%    \begin{macrocode}
\addto\extrasczech{%
  \ifnum\the\sfcode`\.=\@m
    \frenchspacing
    \addto\noextrasczech{\nonfrenchspacing}%
  \fi}
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\czech@q}
%    To simulate some special Czech letters (like
%    t\kern-2pt\char'47\relax), a new macro is defined. It can be used
%    with the letters ({\tt t}, {\tt d}, {\tt l}, and {\tt L}) and
%    adds a {\tt'} to them to simulate a `hook' that should be there.
%    \begin{macrocode}
\def\czech@q#1{#1\kern-2pt\char'47}%
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\czech@w}
%    In the Czech language the accent that appears in \aa ngstr\o m is
%    also used over the letters {\tt u} and {\tt U}. For this purpose
%    the macro |\czech@w| is defined.
%    \begin{macrocode}
\def\czech@w#1{\accent'23 #1}%
%    \end{macrocode}
% \end{macro}
%
%    Our last action is to activate the commands we have just defined,
%    by calling the macro |\selectlanguage|.
%    \begin{macrocode}
\selectlanguage{czech}
%    \end{macrocode}
%    Finally, the category code of {\tt @} is reset to its original
%    value. The macrospace used by |\atcatcode| is freed.
% \changes{czech-1.0a}{15 july 91}{Modified handling of catcode of
