%  \section{The Serbocroatian language}
%
%    The file \file{\filename}\footnote{The file described in this
%    section has version number \fileversion\ and was last revised on
%    \filedate.  A contribution was made by Dejan Muhamedagi\'{c}
%    (\texttt{dejan@yunix.com}).}  defines all the language definition
%    macros for the Serbian language, typeset in a latin script. In a
%    future version support for typesetting in a cyrillic script may
%    be added.
%
%    For this language the character |"| is made active. In
%    table~\ref{tab:serbian-quote} an overview is given of its
%    purpose. One of the reasons for this is that in the Serbian
%    language some special characters are used.
%
%    \begin{table}[htb]
%     \begin{center}
%     \begin{tabular}{lp{8cm}}
%      |"c| & |\"c|, also implemented for the 
%                  lowercase and uppercase s and z.                \\
%      |"d| & |\dj|, also implemented for |"D|                     \\
%      |"-| & an explicit hyphen sign, allowing hyphenation
%                  in the rest of the word.                        \\
%      \verb="|= & disable ligature at this position               \\
%      |""| & like |"-|, but producing no hyphen sign
%                  (for compund words with hyphen, e.g.\ |x-""y|). \\
%      |"`| & for Serbian left double quotes (looks like ,,).      \\
%      |"'| & for Serbian 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{serbian.ldf}}\label{tab:serbian-quote}
%     \end{center}
%    \end{table}
%
%    Apart from defining shorthands we need to make sure taht the
%    first paragraph of each section is intended. Furthermore the
%    following new math operators are defined (|\tg|, |\ctg|,
%    |\arctg|, |\arcctg|, |\sh|, |\ch|, |\th|, |\cth|, |\arsh|,
%    |\arch|, |\arth|, |\arcth|, |\Prob|, |\Expect|, |\Variance|).
%
% \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.
%    \begin{macrocode}
%<*code>
\LdfInit{serbian}\captionsserbian
%    \end{macrocode}
%
%    When this file is read as an option, i.e. by the |\usepackage|
%    command, \texttt{serbian} will be an `unknown' language in which
%    case we have to make it known. So we check for the existence of
%    |\l@serbian| to see whether we have to do something here.
%
%    \begin{macrocode}
\ifx\l@serbian\@undefined
    \@nopatterns{Serbian}
    \adddialect\l@serbian0\fi
%    \end{macrocode}
%
%    The next step consists of defining commands to switch to (and
%    from) the Serbocroatian language.
%
%  \begin{macro}{\captionsserbian}
%    The macro |\captionsserbian| defines all strings used
%    in the four standard documentclasses provided with \LaTeX.
% \changes{serbian-1.0d}{2000/09/20}{Added \cs{glossaryname}}
%    \begin{macrocode}

%
%  \begin{macro}{\dateserbian}
%    The macro |\dateserbian| redefines the command |\today| to
%    produce Serbocroatian dates.
%    \begin{macrocode}
\def\dateserbian{%
  \def\today{\number\day .~\ifcase\month\or

%    \end{macrocode}
%  \end{macro}
%
%  \begin{macro}{\extrasserbian}
%  \begin{macro}{\noextrasserbian}
%    The macro |\extrasserbian| will perform all the extra
%    definitions needed for the Serbocroatian language. The macro
%    |\noextrasserbian| is used to cancel the actions of
%    |\extrasserbian|.  
%
%    For Serbian the \texttt{"} character is made active. This is done
%    once, later on its definition may vary. Other languages in the
%    same document may also use the \texttt{"} character for
%    shorthands; we specify that the serbian group of shorthands
%    should be used.
%
% \changes{serbian-1.0b}{1998/06/16}{Introduced the active \texttt{"}}
%    \begin{macrocode}
\initiate@active@char{"}
\addto\extrasserbian{\languageshorthands{serbian}}
\addto\extrasserbian{\bbl@activate{"}}
%    \end{macrocode}
%    Don't forget to turn the shorthands off again.
% \changes{serbian-1.0c}{1999/12/17}{Deactivate shorthands ouside of
%    Serbian}
%    \begin{macrocode}
\addto\noextrasserbian{\bbl@deactivate{"}}
%    \end{macrocode}
%    First we define shorthands to facilitate the occurence of letters
%    such as \v{c}.
%    \begin{macrocode}
\declare@shorthand{serbian}{"c}{\textormath{\v c}{\check c}}
\declare@shorthand{serbian}{"d}{\textormath{\dj}{\dj}}%%
\declare@shorthand{serbian}{"s}{\textormath{\v s}{\check s}}
\declare@shorthand{serbian}{"z}{\textormath{\v z}{\check z}}
\declare@shorthand{serbian}{"C}{\textormath{\v C}{\check C}}
\declare@shorthand{serbian}{"D}{\textormath{\DJ}{\DJ}}%%
\declare@shorthand{serbian}{"S}{\textormath{\v S}{\check S}}
\declare@shorthand{serbian}{"Z}{\textormath{\v Z}{\check Z}}
%    \end{macrocode}
%
%    Then we define access to two forms of quotation marks, similar
%    to the german and french quotation marks.
%    \begin{macrocode}
\declare@shorthand{serbian}{"`}{%
  \textormath{\quotedblbase{}}{\mbox{\quotedblbase}}}
\declare@shorthand{serbian}{"'}{%
  \textormath{\textquotedblleft{}}{\mbox{\textquotedblleft}}}
\declare@shorthand{serbian}{"<}{%
  \textormath{\guillemotleft{}}{\mbox{\guillemotleft}}}
\declare@shorthand{serbian}{">}{%
  \textormath{\guillemotright{}}{\mbox{\guillemotright}}}
%    \end{macrocode}
%    then we define two shorthands to be able to specify hyphenation
%    breakpoints that behave a little different from |\-|.
% \changes{serbian-1.0d}{2000/09/20}{Changed definition of \texttt{"-}
%    to be the same as for other languages}
%    \begin{macrocode}
\declare@shorthand{serbian}{"-}{\nobreak-\bbl@allowhyphens}
\declare@shorthand{serbian}{""}{\hskip\z@skip}
%    \end{macrocode}
%    And we want to have a shorthand for disabling a ligature.
%    \begin{macrocode}
\declare@shorthand{serbian}{"|}{%
  \textormath{\discretionary{-}{}{\kern.03em}}{}}
%    \end{macrocode}
%  \end{macro}
%  \end{macro}
%
%  \begin{macro}{\bbl@frenchindent}
%  \begin{macro}{\bbl@nonfrenchindent}
%    In Serbian the first paragraph of each section should be indented.
%    Add this code only in \LaTeX.
%    \begin{macrocode}
\ifx\fmtname plain \else
  \let\@aifORI\@afterindentfalse

  \addto\noextrasserbian{\bbl@nonfrenchindent}
\fi
%    \end{macrocode}
%  \end{macro}
%  \end{macro}
%
%  \begin{macro}{\mathserbian}
%    Some math functions in Serbian math books have other names:
%    e.g. |sinh| in Serbian is written as |sh| etc. So we define a
%    number of new math operators.
%    \begin{macrocode}
\def\sh{\mathop{\operator@font sh}\nolimits} % same as \sinh
\def\ch{\mathop{\operator@font ch}\nolimits} % same as \cosh
\def\th{\mathop{\operator@font th}\nolimits} % same as \tanh
\def\cth{\mathop{\operator@font cth}\nolimits} % same as \coth
\def\arsh{\mathop{\operator@font arsh}\nolimits}
\def\arch{\mathop{\operator@font arch}\nolimits}
\def\arth{\mathop{\operator@font arth}\nolimits}
\def\arcth{\mathop{\operator@font arcth}\nolimits}
\def\tg{\mathop{\operator@font tg}\nolimits} % same as \tan
\def\ctg{\mathop{\operator@font ctg}\nolimits} % same as \cot
\def\arctg{\mathop{\operator@font arctg}\nolimits} % same as \arctan
\def\arcctg{\mathop{\operator@font arcctg}\nolimits}
\def\Prob{\mathop{\mathsf P\hskip0pt}\nolimits}
\def\Expect{\mathop{\mathsf E\hskip0pt}\nolimits}
\def\Variance{\mathop{\mathsf D\hskip0pt}\nolimits}
%    \end{macrocode}
%  \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}
