%
%  \section{The Slovak language}
%
%    The file \file{\filename}\footnote{The file described in this
%    section has version number \fileversion\ and was last revised on
%    \filedate.  It was originally written by Jana Chlebikova
%    (\texttt{chlebik@euromath.dk}) and modified by Tobias Schlemmer
%    (\texttt{Tobias.Schlemmer@web.de}). It was then rewritten by
%    Petr Tesa\v r\'ik (\texttt{babel@tesarici.cz}).} defines all the
%    language-specific macros for the Slovak language.
%
%    For this language the macro |\q| is defined. It was 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. Since the the T1
%    font encoding has the corresponding characters it is mapped to |\v|.
%    Therefore we recommend using T1 font encoding. If you don't want to
%    use this encoding, please, feel free to redefine |\q| in your file.
%    I think babel will honour this |;-)|.
%
%    For this language the characters |"|, |'| and |^| are made
%    active. In table~\ref{tab:slovak-quote} an overview is given of
%    its purpose. Also the vertical placement of the
%    umlaut can be controlled this way.
%
%    \begin{table}[htb]
%     \begin{center}
%     \begin{tabular}{lp{8cm}}
%      |"a| & |\"a|, also implemented for the other
%                  lowercase and uppercase vowels.                 \\
%      |^d| & |\q d|, also implemented for l, t and L.             \\
%      |^c| & |\v c|, also implemented for C, D, N, n, T, Z and z. \\
%      |^o| & |\^o|, also implemented for O.                       \\
%      |'a| & |\'a|, also implemented for the other lowercase and
%                    uppercase l, r, y and vowels.                 \\
%      \verb="|= & disable ligature at this position.              \\
%      |"-| & an explicit hyphen sign, allowing hyphenation
%             in the rest of the word.                             \\
%      |""| & like |"-|, but producing no hyphen sign
%             (for compund words with hyphen, e.g.\ |x-""y|).      \\
%      |"~| & for a compound word mark without a breakpoint.       \\
%      |"=| & for a compound word mark with a breakpoint, allowing
%             hyphenation in the composing words.                  \\
%      |"`| & for German left double quotes (looks like ,,).       \\
%      |"'| & for German right double quotes.                      \\
%      |"<| & for French left double quotes (similar to $<<$).     \\
%      |">| & for French right double quotes (similar to $>>$).    \\
%     \end{tabular}
%     \caption{The extra definitions made
%              by \file{slovak.ldf}}\label{tab:slovak-quote}
%     \end{center}
%    \end{table}
%
%    The quotes in table~\ref{tab:slovak-quote} can also be typeset by
%    using the commands in table~\ref{tab:smore-quote}.
%    \begin{table}[htb]
%     \begin{center}
%     \begin{tabular}{lp{8cm}}
%      |\glqq| & for German left double quotes (looks like ,,).   \\
%      |\grqq| & for German right double quotes (looks like ``).  \\
%      |\glq|  & for German left single quotes (looks like ,).    \\
%      |\grq|  & for German right single quotes (looks like `).   \\
%      |\flqq| & for French left double quotes (similar to $<<$). \\
%      |\frqq| & for French right double quotes (similar to $>>$).\\
%      |\flq|  & for (French) left single quotes (similar to $<$).  \\
%      |\frq|  & for (French) right single quotes (similar to $>$). \\
%      |\dq|   & the original quotes character (|"|).        \\
%      |\sq|   & the original single quote (|'|).            \\
%     \end{tabular}
%     \caption{More commands which produce quotes, defined

%    \end{table}
%
%  \subsection{Compatibility}
%
%    Great care has been taken to ensure backward compatibility with
%    \CS\LaTeX.  In particular, documents which load this file with
%    |\usepackage{slovak}| should produce identical output with no
%    modifications to the source.  Additionally, all the \CS\LaTeX{}
%    options are recognized:
%
%    \label{tab:slovak-options}
%    \begin{list}{}
%     {\def\makelabel#1{\sbox0{\Lopt{#1}}%
%        \ifdim\wd0>\labelwidth
%          \setbox0\vbox{\box0\hbox{}} \wd0=0pt \fi
%        \box0\hfil}
%      \setlength{\labelwidth}{2\parindent}
%      \setlength{\leftmargin}{2\parindent}
%      \setlength{\rightmargin}{\parindent}}
%     \item[IL2, T1, OT1]
%       These options set the default font encoding.  Please note
%       that their use is deprecated. You should use the |fontenc|
%       package to select font encoding.
%
%     \item[split, nosplit]
%       These options control whether hyphenated words are
%       automatically split according to Slovak typesetting rules.
%       With the \Lopt{split} option ``je-li'' is hyphenated as
%       ``je-/-li''. The \Lopt{nosplit} option disables this behavior.
%
%       The use of this option is strongly discouraged, as it breaks
%       too many common things---hyphens cannot be used in labels,
%       negative arguments to \TeX{} primitives will not work in
%       horizontal mode (use \cs{minus} as a workaround), and there are
%       a few other peculiarities with using this mode.
%
%     \item[nocaptions]
%
%       This option was used in \CS\LaTeX{} to set up Czech/Slovak
%       typesetting rules, but leave the original captions and dates.
%       The recommended way to achieve this is to use English as the main
%       language of the document and use the environment |otherlanguage*|
%       for Czech text.
%
%     \item[olduv]
%       There are two version of \cs{uv}.  The older one allows the use
%       of \cs{verb} inside the quotes but breaks any respective kerning
%       with the quotes (like that in \CS{} fonts).  The newer one honors
%       the kerning in the font but does not allow \cs{verb} inside the
%       quotes.
%
%       The new version is used by default in \LaTeXe{} and the old version
%       is used with plain \TeX.  You may use \Lopt{olduv} to override the
%       default in \LaTeXe.
%       
%     \item[cstex]
%       This option was used to include the commands \cs{csprimeson} and
%       \cs{csprimesoff}.  Since these commands are always included now,
%       it has been removed and the empty definition lasts for compatibility.
%    \end{list}
%
% \StopEventually{}
%
%  \subsection{Implementation}
%
%    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{slovak-1.2i}{1996/11/03}{Now use \cs{LdfInit} to perform
%    initial checks} 
%    \begin{macrocode}
%<*code>
\LdfInit\CurrentOption{date\CurrentOption}
%    \end{macrocode}
%
%    When this file is read as an option, i.e. by the |\usepackage|
%    command, \texttt{slovak} will be an `unknown' language in which
%    case we have to make it known. So we check for the existence of
%    |\l@slovak| to see whether we have to do something here.
%
% \changes{slovak-1.2d}{1994/06/26}{Now use \cs{@nopatterns} to

%    Of course, this does not work well with \LaTeX$\:$2.09, but I

%    Initialize active quotes.  \CS\LaTeX{} provides a way of
%    converting English-style quotes into Slovak-style ones.  Both
%    single and double quotes are affected, i.e. |``text''| is
%    converted to something like |,,text``| and |`text'| is converted
%    to |,text`|.  This conversion can be switched on and off with
%    \cs{csprimeson} and \cs{csprimesoff}.\footnote{By the way, the
%    names of these macros are misleading, because the handling of
%    primes in math mode is rather marginal, the most important thing
%    being the handling of quotes\ldots}
%
%    These quotes present various troubles, e.g. the kerning is broken,
%    apostrophes are converted to closing single quote, some primitives
%    are broken (most notably the |\catcode`\|\meta{char} syntax will
%    not work any more), and writing them to \file{.aux} files cannot
%    be handled correctly.  For these reasons, these commands are only
%    available in \CS\LaTeX{} compatibility mode.

%    The thing is that \LaTeXe{} core only supports the T1 encoding
%    and does not bother changing the uc/lc/sfcodes when encoding
%    is switched. :( However, the IL2 encoding \emph{does} change
%    these codes, so if encoding is switched back from IL2, we must
%    also undo the effect of this change to be compatible with
%    \LaTeXe.  OK, this is not the right\textsuperscript{TM} solution
%    but it works.  Cheers to Petr Ol\v s\'ak.
