%
%  \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
%    (\texttt{LOKAJICK@CERNVM}).}  defines all the language definition
%    macros for the Czech language.
%
%    For this language |\frenchspacing| is set and two macros |\q| and
%    |\w| for easy access to two accents are defined.
%
%    The command |\q| is used with the letters (\texttt{t},
%    \texttt{d}, \texttt{l}, and \texttt{L}) and adds a \texttt{'} 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
%    ring-accent which appears in \aa ngstr\o m over the letters
%    \texttt{u} and \texttt{U}.
%
% \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{czech-1.3h}{1996/11/02}{Now use \cs{LdfInit} to perform
%    initial checks} 
%    \begin{macrocode}
%<*code>
\LdfInit{czech}\captionsczech
%    \end{macrocode}
%
%    When this file is read as an option, i.e. by the |\usepackage|
%    command, \texttt{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}{1991/10/27}{Removed use of \cs{@ifundefined}}
% \changes{czech-1.1}{1992/02/15}{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\l@czech\@undefined
    \@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 documentclasses provided with \LaTeX.
% \changes{czech-1.1}{1992/02/15}{Added \cs{seename}, \cs{alsoname}
%    and \cs{prefacename}}
% \changes{czech-1.3f}{1995/07/04}{Added \cs{proofname} for AMS-\LaTeX}
% \changes{czech-1.3g}{1996/02/12}{Fixed two errors and provided
%    translation for `proof'} 
% \changes{czech-1.3j}{2000/09/19}{Added \cs{glossaryname}}

%
%  \begin{macro}{\dateczech}
%    The macro |\dateczech| redefines the command |\today| to produce
%    Czech dates.

%    to save memory}

%
%  \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}{1992/07/07}{Removed typo, \cs{q} was restored
%    twice, once too many.}
% \changes{czech-1.3e}{1995/03/15}{Use \LaTeX's \cs{v} and \cs{r}
%    accent commands}
%    \begin{macrocode}
\addto\extrasczech{\babel@save\q\let\q\v}
\addto\extrasczech{\babel@save\w\let\w\r}
%    \end{macrocode}
%    For Czech texts |\frenchspacing| should be in effect. We make
%    sure this is the case and reset it if necessary.
% \changes{czech-1.3e}{1995/03/14}{now use \cs{bbl@frenchspacing} and
%    \cs{bbl@nonfrenchspacing}}
%    \begin{macrocode}
\addto\extrasczech{\bbl@frenchspacing}
\addto\noextrasczech{\bbl@nonfrenchspacing}
%    \end{macrocode}
%  \end{macro}
%  \end{macro}
%
%  \begin{macro}{\v}
%    \LaTeX's normal |\v| accent places a caron over the letter that
%    follows it (\v{o}). This is not what we want for the letters d,
%    t, l and L; for those the accent should change shape. This is
%    acheived by the following.
%    \begin{macrocode}
\AtBeginDocument{%
  \DeclareTextCompositeCommand{\v}{OT1}{t}{%
    t\kern-.23em\raise.24ex\hbox{'}}
  \DeclareTextCompositeCommand{\v}{OT1}{d}{%

  \DeclareTextCompositeCommand{\v}{OT1}{l}{\lcaron{}}

%    \end{macrocode}
%
%  \begin{macro}{\lcaron}
%  \begin{macro}{\Lcaron}
%    Fot the letters \texttt{l} and \texttt{L} we want to disinguish
%    between normal fonts and monospaced fonts.

  \ifdim\wd0>\wd\tw@\relax
    l\kern-.13em\raise.24ex\hbox{'}\kern-.11em%
  \else
    l\raise.45ex\hbox to\z@{\kern-.35em '\hss}%
  \fi}
\def\Lcaron{%

    L\raise.24ex\hbox to\z@{\kern-.28em'\hss}%
  \else
    L\raise.45ex\hbox to\z@{\kern-.40em '\hss}%
  \fi}
%    \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.
