-%    Apart from defining shorthands we need to make sure taht the

-%    |\arch|, |\arth|, |\arcth|, |\Prob|, |\Expect|, |\Variance|).
+%    Macro |\today| prints the date in Serbian. Alternatively, if attribute \Lopt{datei} is used,
+%    |\today| prints the current date, but prints `juni' and `juli' for `June' and `July'.
+%    If you prefer to use `juni' and `juli' instead of default `jun' and `jul',
+%    use the \Lopt{datei} attribute. Also, the |\today*| macro prints the date without dot after the year
+%    (used when after the date is the punctuation mark, such as comma).
+%     Alternatively, the commands |\todayRoman| and |\todayRoman*| prints the current date using Roman numerals for months.

+%
+% By default, a ekavian spelling is enabled. For ijekavian
+% spelling can be enabled by setting the attribute to \Lopt{ijekav}. To set
+% an attribute, put the |\languageattribute| macro within a document preamble after
+% \babel, for example,
+%\begin{verbatim}
+%    \usepackage[english,serbian]{babel}
+%    \languageattribute{serbian}{ijekav}
+%\end{verbatim}
+% Setting the \Lopt{ijekav} attribute changes the built-in strings (caption names).
+% For example, the part will be entitled as
+% `Deo' by default and as `Dio' if the
+% Serbian language attribute is set to \Lopt{ijekav}.
+% Same result can be achieved using a modifier as follows:
+%\begin{verbatim}
+%    \usepackage[english,serbian.ijekav]{babel}
+%\end{verbatim}
+% Using a modifier in a package option is often better. A modifier is set after
+% the language name, and is prefixed with a dot (only when the language is set
+% as package option — neither global options nor the main key accept them).
+% Also, it's possible to use more than one attribute:
+%\begin{verbatim}
+%    \usepackage[english,serbian.ijekav.datei.quotes]{babel}
+%\end{verbatim}
+%
+% The file \file{serbian.ldf} is designed to work both with
+% legacy non-unicode (8-bit) and new Unicode encodings of the source document
+% files (input encodings) and of the font files (font encodings).

+%
 %    The macro |\LdfInit| takes care of preventing that this file is
 %    loaded more than once, checking the category code of the
 %    \texttt{@} sign, etc.

 %
-%    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.
+%    First, we check if Lua\LaTeX\ or Xe\LaTeX\ is running. If so, we set
+%    boolean key |\if@srb@uni@ode| to true.
+%
+%    \begin{macrocode}
+\ifdefined\if@srb@uni@ode
+  \PackageError{babel}{if@srb@uni@ode already defined.}

+\ifdefined\luatexversion \@srb@uni@odetrue \else
+\ifdefined\XeTeXrevision \@srb@uni@odetrue \fi\fi
+%    \end{macrocode}
+%
+%    Check if hyphenation patterns for the Serbian language have been
+%    loaded in \file{language.dat}. Namely, we check for the existence of
+%    |\l@serbian|. If it is not defined, we declare Serbian as dialect
+%    for the default language number 0 which almost for sure is English.

-%    The next step consists of defining commands to switch to (and
-%    from) the Serbocroatian language.
+%    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. We save the original double quote character
+%    in the |\dq| macro to keep it available. The shorthand \texttt{"-}
+%    should be used in places where a word contains an explictit
+%    hyphenation character. According to the rules of the Serbian language, when
+%    a word break occurs at an explicit hyphen it must appear both at the end of the
+%    first line and at the beginning of the second line.
