+\section{The Russian Language Definition File}
+
+The file \file{\filename}\footnote{The file described in this document
+has the version number \fileversion\ and was last revised on \filedate.}
+is the source file for the Russian Language Definition file
+\file{russianb.ldf} to be loaded by the \babel\ package with
+the option \Lopt{russian}. It was derived by Igor A.
+Kotelnikov from the original version of \file{\filename}, first
+released by Olga Lapko and Johannes Braam and then
+adapted to the T2* and X2 Cyrillic encodings
+by Vladimir Volovich and Werner Lemberg.
+
+Starting the version 1.2, \file{russianb.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). This is
+achieved by excluding (bypassing) the |\cyr...| macros, which map every letter
+in a source file with given input encoding to a corresponding code point in a
+font file with a given font encoding when running modern engines, such as
+Lua\LaTeX\ or Xe\LaTeX, in native unicode mode instead of legacy engines, such
+as \LaTeX\ or PDF\LaTeX, or unicode engines in a compatibility (8-bit) mode. A
+few obsolete and controversial macros has been eliminated in first public
+release of version 1.2 of \file{russianb.ldf}.
+
+The version 1.3 of \file{russianb.ldf} has been adapted to new features
+introduced in the version 3.9 of the \pkg{babel} package. In particular, the
+language attribute \Lopt{ancient} has been introduced to support typesetting
+ancient and Church Slavonic books.
+
+
+\section{Usage}
+
+Typesetting Russian texts implies that a special input and output
+encodings should be used. Input encodings are those which are used in source
+(\texttt{.tex}) file. Output encoding is also known as the font encoding. It is
+implemented within the font files.
+
+Generally, the user may choose between different available Cyrillic
+encodings provided. The current support for Cyrillic uses LH family of
+MetaFont fonts and theirs Postscript versions such as CM-super. Lua\LaTeX\ and
+Xe\LaTeX, being the Unicode-based succeeders of \LaTeX, allow also for any
+Open Type (OTF) and True Type (TTF) fonts which has Cyrillic script, e.g.
+Computer Modern Unicode, Linux Libertine, and many other system fonts
+that came with Linux and Windows operating systems.
+
+With the advent of Unicode, \LaTeX\ community are moving towards eliminating
+all existing encodings in favor of Unicode, but nowadays one should take
+care when switching from \LaTeX\ to Lua\LaTeX\ or Xe\LaTeX\ since
+different packages should be loaded for those compilers.
+
+Since earlier versions \pkg{babel} did not
+support Xe\LaTeX\ (at least for some languages including Russian), the
+\pkg{polyglossia} package was generally recommended in the past for
+use with Xe\LaTeX\ as a replacement for \pkg{babel}. Nowadays, \pkg{babel}
+can be used with any engines, including \LaTeX, PDF\LaTeX, Lua\LaTeX, and
+Xe\LaTeX. Nevertheless some troubles may occur with some languages which
+have no promptly updated \file{.ldf} files.
+
+
+\subsection{\LaTeX}
+
+When user's document is compiled with \file{latex.exe} or \file{pdflatex.exe},
+recommended set of packages includes the \pkg{inputenc} and \pkg{fontenc}
+package. They should be loaded before \pkg{babel}, for example,
+\begin{verbatim}
+ \usepackage[T1,T2A]{fontenc}
+ \usepackage[utf8]{inputenc}
+ \usepackage[english,russian]{babel}
+\end{verbatim}
+Some variations in the order of package loading are allowed in this case
+but it is better to follow one and the same convention at all circumstances:
+the \pkg{babel} packgage should go last, and \pkg{fontenc} must be the first.
+
+Input encoding should be declared as option to the \pkg{inputenc}
+package. Known Cyrillic encodings include \texttt{cp866} (MS DOS),
+\texttt{cp1251} (Windows), \texttt{koi8-u} (UNIX) and their variants.
+Nowadays, this list is appended with \texttt{utf8} input encoding.
+
+Output encodings (also known as font encodings) are declared as options to
+the \pkg{fontenc} package. Known Cyrillic encodings are \texttt{T2A},
+\texttt{T2B}, \texttt{T2C}, \texttt{LCY}, and \texttt{X2};
+\texttt{LWN} is excluded from Russian support stating version 1.2 of
+\file{\filename} since \texttt{LWN} is excluded from the \pkg{cyrillic}
+bundle of related files.
+
+
+\subsection{Lua\LaTeX}
+
+If Unicode fonts are not available, Lua\LaTeX\ can run in compatibility
+(8-bit) mode to use same font as \LaTeX\ does. However the package
+\pkg{inputenc} does not work with Lua\LaTeX\ and should be substituted with
+\pkg{luainputenc}. Source file is to be converted to \texttt{UTF8}
+(Unicode-8) encoding; it is the only input encoding accepted by
+Lua\LaTeX. The 8-bit mode is invoked by the following sequence of packages:
+\begin{verbatim}
+ \usepackage[T1,T2A]{fontenc}
+ \usepackage[lutf8]{luainputenc}
+ \usepackage[english,russian]{babel}
+\end{verbatim}
+\unskip
+The order of the packages is crucial for Lua\LaTeX\ in 8-bit mode. Since both
+\pkg{luainputenc} and \pkg{babel} should know what is a selected font encoding,
+the \pkg{fontenc} package should be loaded first. Input encoding management for
+Lua\TeX\ is needed only for compatibility with old documents. For new
+documents, using UTF-8 encoding and Unicode fonts is strongly recommended.
+\emph{You've been warned!} See
+\href{http://tex.stackexchange.com/questions/31709/can-one-instruct-lualatex-to-use-t2a-encoded-fonts}%
+{tex.stackexchange.com/questions/31709/can-one-instruct-lualatex-to-use-t2a-encoded-fonts}.
+
+
+To invoke Unicode mode, one needs to load the \pkg{fontspec} package instead
+of \pkg{luainputenc} and \pkg{fontspec} and explicitly indicate
+which fonts should be used for romanic, sans-serif and monospaced
+types. Next example shows how to load Computer Modern Unicode fonts, which is a
+part of all modern \LaTeX\ distributions:
+\begin{verbatim}
+\usepackage{fontspec}
+ \defaultfontfeatures{Renderer=Basic,Ligatures={TeX}}
+ \setmainfont{CMU Serif}
+ \setsansfont{CMU Sans Serif}
+ \setmonofont{CMU Typewriter Text}
+\usepackage[english,russian]{babel}
+\end{verbatim}
+\unskip
+The |\defaultfontfeatures| declares default font features for subsequent
+|\setmainfont| (which sets romanic fonts), |\setsansfont| (sans-serif) and
+|\setmonofont| (monospaced font). Font features can be set up on per font
+bases; for example
+\begin{verbatim}
+\usepackage{fontspec}
+ \setmainfont[Renderer=Basic,Ligatures={TeX}]{CMU Serif}
+ \setsansfont[Renderer=Basic,Ligatures={TeX,Historic}]{CMU Sans Serif}
+ \setmonofont{CMU Typewriter Text}
+\usepackage[english,russian]{babel}
+\end{verbatim}
+\unskip
+Here |Renderer=Basic,Ligatures={TeX}| activates ligatures which are existed
+in \LaTeX.
+
+Recall that the language enlisted last in the list of options of the \pkg{babel}
+package is assumed to be the main language of the document, which is also active
+language right after |\begin{document}|. As of version 3.9, the main language
+can be set as a value of the |main| option as follows
+\begin{verbatim}
+\usepackage{fontspec}
+\usepackage[english,main=russian,german]{babel}
+\end{verbatim}
+%\unskip
+
+
+
+\subsection{Xe\LaTeX}
+
+In Xe\LaTeX, there is also a special mode for 8-bit compatibility.
+One can use |\XeTeXinputencoding| to change the input encoding
+temporarily, and the \texttt{"bytes"} encoding makes Xe\LaTeX\ works
+like a 8-bit \LaTeX\ engine:
+\begin{verbatim}
+\XeTeXinputencoding "bytes"
+\usepackage[utf8]{inputenc}
+\usepackage[T2A]{fontenc}
+\usepackage[english,russian]{babel}
+\end{verbatim}
+\unskip
+Xe\TeX\ can use a different input encoding but it always uses the Unicode
+internally, so that |\XeTeXinputencoding| performs a conversion of the input
+into Unicode;
+see \href{http://tex.stackexchange.com/questions/36188/do-xetex-and-luatex-always-use-unicode}
+{tex.stackexchange.com/questions/36188/do-xetex-and-luatex-always-use-unicode}.
+
+
+Unicode mode is set up same way as for Lua\LaTeX, however the option
+|Renderer=Basic| can be dropped:
+\begin{verbatim}
+\usepackage{fontspec}
+ \defaultfontfeatures{Ligatures={TeX}}
+ \setmainfont{CMU Serif}
+ \setsansfont{CMU Sans Serif}
+ \setmonofont{CMU Typewriter Text}
+\usepackage[english,russian]{babel}
+\end{verbatim}
+%\unskip
+
+
+\subsection{Modern and Ancient spelling}
+\label{ssec:speeling}
+
+By default, a modern spelling is enabled. For Church Slavonic and other old books
+ancient spelling can be enabled by setting the attribute to \Lopt{ancient}. To set
+an attribute, put the |\languageattribute| macro within a document preamble after
+\babel, for example,
+\begin{verbatim}
+\usepackage[english,russian]{babel}
+\languageattribute{russian}{ancient}
+\end{verbatim}
+Setting the \Lopt{ancient} attribute changes the built-in strings (caption names)
+and a date format. For example, the bibliography will be entitled as
+`\textcyrillic{Литература}' by default and as `\textcyrillic{Библіографія}' if the
+Russian language attribute is set to \Lopt{ancient}.
+%Default behavior is equivalent to setting the Russian language attribute to \Lopt{modern}.
+
+
+\section{User's commands}
+
+In a multilingual document, some typographic rules are language
+dependent and should apply to the whole document.
+
+%As of version~1.2, \file{russianb.ldf} behaves differently
+%according to \babel's \emph{main language} defined as the \emph{last}
+%option. When Russian is
+%|babel|'s main language, it adjusts global layout of the document
+%according to typographical conventions of Russian language. Namely,
+%\file{russianb.ldf} makes the following changes to global layout even
+%in the parts where Russian is not current language:
+%\begin{enumerate}
+%\item
+% the first paragraph of any section becomes indented (\LaTeX{} only).
+% (this is obsolete statement starting from version 1.2a)
+%\end{enumerate}
+
+Regarding local typography, the macro |\selectlanguage{russian}|
+switches to the Russian language, with the following effects:
+\begin{enumerate}
+\item Russian hyphenation patterns are made active;
+\item |\today| prints the date in Russian;
+\item the caption names are translated into Russian
+ (\LaTeX{} only);
+\item emdash typed by the ligature |---| might be 20\% shorter when Russian
+is the current language; the result depends on the current encoding; |---|
+always produce long emdash in Lua\TeX\ and Xe\TeX\ since these engines
+use same encodings for all languages;
+\item emdash typed by the ligature |"---| in Russian is 20\% shorter, however
+the ligature |"---| might not be defined in other languges; a
+ shorter emdash (i.e. |\cyrdash|) can be typeset in any language using
+ special macros enlisted in table \ref{tab:russian-quote}.
+\end{enumerate}
+
+By default, a modern spelling is used for built-it strings (caption names) and
+the date. The spelling can be reverted to ancient by setting the language
+attribute to \Lopt{ancient} in the document preamble as discussed in
+Sec.~\ref{ssec:speeling}.
+
+Since Russian has its own numbering system, \file{russianb.ldf} adds macros
+|\asbuk|\marg{counter} and |\Asbuk|\marg{counter} for formatting numbers appropriately the alphabetic
+sequence in the Russian alphabet. Additional commands are provided
+to typeset quotes:
+\begin{enumerate}
+\item French quotation marks can be entered using the commands
+ |\guillemotleft| and |\guillemotright| which work in \LaTeXe\
+ and Plain\TeX.
+\item German quotation marks can be entered using the commands
+ |\glqq| and |\grqq| which work in \LaTeXe\ and Plain\TeX.
+\end{enumerate}
+
+The macro |\Russian| is now defined as an alias for
+|\selectlanguage{russian}|, and its ``opponent'' |\English|, existed
+in \file{russianb.ldf} prior to version 1.2 has been removed since the Russian
+language definition file is wrong place for definition of macros which
+switch to a distinct other language.
+
+The macro |\textcyrillic|\marg{text} is intended to typeset small chunks of text
+in Russian; it is essentially an alias for |\foreignlanguage{russian}|\marg{text}.
+
+
+\subsection{Active character}
+
+Table~\ref{tab:russian-quote} shows macros and active string which can be
+used to typeset various dashes and quotes.
+In the Russian language, the character |"| is made active. It can be
+considered as second escape character in addition to |\|. Some dashes and
+all quotes can be typed using both active character |"| and ordinary
+macros as indicated in the table. However, some shorthanded hyphenations
+have no macro counterpart.
+

+\end{table}
+Note that the standard soft hyphen |\-| is equivalent to |\babelhyphen*{soft}|.
+
+\medskip
+
+The quotation marks traditionally used in Russian were borrowed from
+other languages (e.g., French and German) so they keep their original
+names.
+
+The French quotes are also available as ligatures `|<<|' and `|>>|' in
+8-bit Cyrillic font encodings (\texttt{LCY}, \texttt{X2}, \texttt{T2*})
+and in unicode encodings (\texttt{EU1} and \texttt{EU2})
+and as `|<|' and `|>|' characters in 7-bit Cyrillic font encodings
+(\texttt{OT2} and \texttt{LWN}).
+
+In Unicode encodings \texttt{EU1} and \texttt{EU2} cyrdashes and quotes
+can be typed as single character if text editor makes it possible to
+insert characters which absent of standard keyboard. This method works
+as well for 8-bit fonts encoded according to \texttt{T2A} if source file
+is encoded with \texttt{cp1251} or {utf8}.
+
+By default, active double quote is switched on. It can be switched off
+any time using |\shorthandon{"}| and the switched on again using
+|\shorthandon{"}|. The aliases |\mdqoff| and |\mdqon| for these two macros
+has been removed from \file{russianb.ldf} starting from version 1.3 in favour of
+the macros |\shorthandon| and |\shorthandoff| provided in the \pkg{babel} core.
+
+
+\subsection{Math commands}
+
+\file{russianb.ldf} defines few macros than can be used independently
+of current language. These are 9 macros to be used in math mode to type

+%
+% \section{\TeX{}nical details}
+%
+% The packages \pkg{inputenc} and \pkg{luainputenc}
+% make Cyrillic letters active so that compiler converts them into
+% corresponding |\cyr...| macro at compilation time.
+% For example, Russian letter `a' matches
+% macro |\cyra|, and capital Russian letter `A' matches |\CYRA|. The
+% package \pkg{fontenc} then matches every macro |\cyr...| to corresponding
+% glyph in font file depending on declared font encoding.
+%
+% Nowadays, Unicode makes |\cyr...| macros outdated since both source
+% file and font file are encoded consistently. These macros
+% should therefore be removed because mixing them with unicode characters
+% breaks sorting mechanism of such utilities as \file{bibtex} and
+% \file{makeindex}. For the sake of backward compatibility, |\cyr...| are
+% still kept for \LaTeX, but they are bypassed if Lua\LaTeX\ or Xe\LaTeX\
+% are detected.
+%
+% Some inconsistences of prior versions of \file{\filename} was also
+% overcame in the version 1.2. Those users who used |\selectlanguage| macro,
+% defined in the core \pkg{babel} system, to switch between
+% different languages should not worry. However, the macros
+% |\Russian|, |\Englsih| and their aliases |\Rus|, |\cyr|,
+% |\Eng| are modified or removed as they did not
+% conform the mechanism of language switching encoded into the
+% core of \pkg{babel} and therefore can mess it.

+%
+%
+% \subsection{Initial setup}
+%
+% The macro |\LdfInit| performs a couple of standard checks that
+% must be made at the beginning of a language definition file,
+% such as checking the category code of the \texttt{@}-sign, preventing
+% the \file{.ldf} file from being processed twice, etc.
+%
+% \changes{russianb-1.1d}{1996/11/03}{Now use \cs{LdfInit} to perform
+% initial checks}
+% \changes{russianb-1.1e}{1996/12/29}{Added closing brace to second
+% argument of \cs{LdfInit}}
+% \begin{macrocode}
+%<*code>
+\LdfInit{russian}{captionsrussian}
+% \end{macrocode}
+%
+% First, we check if Lua\LaTeX\ or Xe\LaTeX\ is running. If so, we set
+% boolean key |\if@uni@ode| to true. It will be used to eliminate |\cyr...|
+% commands, which were introduced in \LaTeX2e\ to handle various
+% Cyrillic input encoding. With the advent of unicode \LaTeX\ is
+% moving to universal input encoding, so we consider these |\cyr...|
+% commands as obsolete. They are preserved though for backward
+% compatibility in case if \LaTeX\ or PDF\LaTeX\ are running.
+%
+% We don't load the \pkg{ifluatex} or \pkg{ifxetex} package because
+% |\RequirePackage| is not allowed at the stage of processing options
+% (note that babel loads this file right when it processes its own options)
+% but we borrow code from these packages.
+%
+% \changes{russianb-1.2}{2011/10/20}{Check for LuaTeX}
+% \begin{macrocode}
+\ifdefined\if@uni@ode
+ \PackageError{babel}{if@uni@ode already defined.\MessageBreak
+ Please contact author of russianb.ldf}
+ \relax
+\fi
+\newif\if@uni@ode
+\ifdefined\luatexversion \@uni@odetrue \else
+\ifdefined\XeTeXrevision \@uni@odetrue \fi\fi
+% \end{macrocode}
+%
+% Check if hyphenation patterns for the Russian language have been
+% loaded in \file{language.dat}. Namely, we check for the existence of
+% |\l@russian|. If it is not defined, we declare Russian as dialect
+% for the default language number 0 which almost for sure is English.
+%
+% \begin{macrocode}
+\ifx\l@russian\@undefined
+ \@nopatterns{Russian}
+ \adddialect\l@russian0
+\fi
+% \end{macrocode}
+% Now |\l@russian| is always defined.
+%
+% \subsection{Output encoding}
+%
+% We need to know font encoding that is supposed to be
+% active at the end of the \babel\ package. Default font encoding, set by
+% \LaTeX\ core, is \texttt{OT1}. This can be changed by the \pkg{fontenc}
+% package in case of \LaTeX\ and by \pkg{fontspec} package in case of
+% Lua\LaTeX. It matters weather these packages are loaded before of after
+% \pkg{babel}. In the latter case or if these packages are not loaded at all,
+% \file{russianb.ldf} ignores their effect and tries to provide some
+% reasonable settings. In particular, \texttt{T2A} will be selected for
+% Russian language if \LaTeX\ is running but \texttt{EU1} in case of
+% Xe\LaTeX\ and \texttt{EU2} in case of Lua\LaTeX.
+%
+% \begin{macro}{\latinencoding}
+% \changes{russianb-1.2}{2011/10/20}{Removed \cs{latinencoding}}
+%
+% The macro |\latinencoding| keeps the name of Latin encoding. It is
+% defined in \file{babel.def} and is wrapped into |\AtBeginDocument| to allow
+% for late loading \pkg{fontenc}. Therefore it does not matter
+% whether \pkg{babel} is loaded before or after the \pkg{fontenc}.
+% As of version 1.2, definition of |\latinencoding| was removed from
+% \file{russianb.ldf} since it is overruled in \file{babel.def}.
+% For example, after
+% \begin{verbatim}
+% \usepackage[T1,T2A]{fontenc}
+% \usepackage[english,russian]{babel}
+% \end{verbatim}%
+% \unskip
+% as well as after
+% \begin{verbatim}
+% \usepackage[english,russian]{babel}
+% \usepackage[T1,T2A]{fontenc}
+% \end{verbatim}%
+% \unskip
+% |\latinencoding| will be set to \texttt{T1}.
+% After
+% \begin{verbatim}
+% \usepackage[english,russian]{babel}
+% \end{verbatim}%
+% \unskip
+% |\latinencoding| will be \texttt{OT1}.
+%
+% In Unicode mode, the package \pkg{fontspec} should be loaded instead of
+% \pkg{fontenc} to make font preparation; \pkg{fontspec} loads the package
+% \pkg{xunicode} which sets current encoding (kept in |\cf@encoding|) to
+% \texttt{EU1} for Xe\LaTeX\ and \texttt{EU2} for Lua\LaTeX, and the \pkg{babel}
+% package sets the macro |\latinencoding| to |\cf@encoding|. Since \pkg{babel} scan
+% for value |\cf@encoding| within |\AtBeginDocument|, |\latinencoding| will
+% be set to either \texttt{EU1} for Xe\LaTeX\ or \texttt{EU2} for Lua\LaTeX\
+% no matter which of the packages, \pkg{babel} or \pkg{fontspec} is loaded first.
+%
+% \end{macro}
+%
+% \Describe\cyrillicencoding{}
+% There is a limited list of encodings appropriate for Cyrillic text. We
+% will look which of them is declared and keep its name in the macro
+% |\cyrillicencoding|.
+% Correct (but obsolete and now deleted) 7-bit Cyrillic encoding is
+% \texttt{LWN}.
+% Correct 8-bit Cyrillic encodings are
+% \texttt{T2A} (default for 8-bit compilers), \texttt{T2B}, \texttt{T2C},
+% \texttt{LCY} and \texttt{X2}.
+% Correct utf8 encodings are
+% \texttt{EU1} (default for Xe\LaTeX),
+% \texttt{EU2} (default for Lua\LaTeX).
+%
+% In 8-bit (\LaTeX) mode, user may choose between different non-unicode Cyrillic
+% encodings---e.g., \texttt{X2} or \texttt{LCY}.\@ If user wants
+% to use another font encoding rather than default (\texttt{T2A}),
+% he has to load the corresponding file \emph{before} \file{babel.sty}.
+%
+% Remember that for the Russian language, the \texttt{T2A} encoding is
+% better than \texttt{X2}, because \texttt{X2} does not contain Latin
+% letters, and users should be very careful to switch the language
+% every time they want to typeset a Latin word inside a Russian phrase
+% or vice versa.
+%
+%
+% We parse the |\cdp@list| containing encodings known to \LaTeX\
+% in the order they were loaded by the time when \pkg{babel} is loaded.
+% We set the |\cyrillicencoding| to the \emph{last} loaded encoding in the
+% list of supported Cyrillic encodings: \texttt{OT2}, \texttt{LCY},
+% \texttt{X2}, \texttt{T2C}, \texttt{T2B}, \texttt{T2A}. In Unicode mode
+% we also try the unicode encodings \texttt{EU1} and \texttt{EU2}; 8-bit
+% encodings are kept for unicode compilers (Lua\LaTeX\ and Xe\LaTeX) since
+% they can run in compatibility (8-bit) mode.

+% \DescribeOther\cyr{}
+% \DescribeOther\cyrillictext{}
+% For the sake of backward compatibility we keep the macro |\Russian|
+% but redefine its meaning; now |\Russian| is simply an alias for
+% |\selectlanguage{russian}|.
+%
+% We define |\cyrillictext| and its alias |\cyr| but remove another alias
+% |\Rus|; these macros are intended for use within \texttt{babel} macros and
+% do not perform complete switch of the language.
+% In particular, they to do no switch captions and the name of current
+% language stored in the macro |\languagename|. This inconsistency might
+% break some assumptions embedded into \pkg{babel}'s.
+% For example, the |\iflanguage| macro will fail.
+%
+% Second, |\cyrillictext| does
+% not activate shorthands, so that |"<|, |">|, |"`|, |"'|,
+% |"---|, e.t.c. will not work.
+%
+% And third, |\cyrillictext| does not write its trace
+% to \file{.aux} file, which might result in wrong typesetting of
+% table of content, list of table and list of figures in multilingual
+% documents.
+%
+% Due to any of these reasons the use of the declaration |\cyrillictext| and
+% its aliases in ordinary text is strongly discouraged. Instead of the
+% declaration |\cyrillictext| it is recommended to use |\Russian| or the
+% command |\foreignlanguage| defined in the \pkg{babel} core; their
+% functionality is similar to |\selectlanguage{russian}| but they did not
+% switch caption names, dates and shorthands.

+% were defined through german quotes |\glqq| and |\grqq|, which in their turn
+% are defined in \pkg{babel.def} via |\quotedblbase| and |\textquotedblleft|,
+% respectively. It occurred, that old definition caused errors in Unicode

+%
+% Prior to version 1.2, the shorthands |"<| and |">| were
+% declared to be equivalents for the French quotes |\flqq| and |\frqq|,
+% respectively. They are defined in \pkg{babel.def} via |\guillemotleft| and
+% |\guillemotrigh|. However, |\flqq| and |\guillemotleft| (and their right
+% counterparts) are typeset differently if current encoding is not
+% \texttt{T1}. Therefore, since v.1.2, we define |"<| and |">| directly

+% All these 3 internal macros call for |\cyrdash|, which type Cyrillic
+% emdash, but put different spaces around the dash.
+%
+% |\@Acdash| is invoked by |"---|. It types Cyrillic emdash to be used
+% inside a text and puts an unbreakable thin space before the dash if a
+% \textit{space} is placed before |"---| in the source file;
+% can be used after display maths formulae, formatted lists, enumerations, etc.

+% \end{macrocode}
+%
+% |\@Bcdash| is invoked by |"--~|. It types Cyrillic emdash in compound
+% names (like Mendeleev--Klapeiron); requires no space characters around and
+% adds extra space after the dash.

+% \Describe\cyrdash{}
+% The |\cyrdash| can be defined in a fontenc file as it is done for
+% the \texttt{T2*} encodings. We provide fake definition of |\cyrdash| only if
+% it is not defined there.
+%
+% Cyrillic \texttt{T2*} fonts contains shorter (Cyrillic) emdash. It can be
+% typeset also via the ligature |---|. So, if |\laticencoding| differs from
+% \texttt{T2*} switching of languages also changes the emdash length typed as
+% ligature in the source file.

+% \subsection{Switching to and from Russian}
+%
+% Now we define additional macros used to reset current language to
+% Russian and back
+% to some original state. The package \pkg{babel} based on the assumption
+% that original state is characterized by a Latin encoding. Previously,
+% for back reset the macro |\OriginalTeX| was used, but now use |\latintext|
+% for the same purpose.
+%
+%
+% \subsubsection{Caption names}
+%
+% First, we define Russian equivalents for Russian caption names.
+%
+% \Describe\captionsrussian{}
+% The macro |\captionsrussian| defines caption names used in the
+% four standard document classes provided with \LaTeX. The macro |\cyr|
+% activates Cyrillic encoding. It could be dropped if we would be sure
+% that Russian captions are called only if current language is Russian.
+% However, the macros such as |\Russian| do not conform to strict rules
+% of the package \pkg{babel} as explained in the above.
+%
+% As of version v.1.2 we eliminate |\cyr...| macros from caption names
+% if unicode engine is running. In the latter case, Cyrillic letters are typed
+% in by their unicode code-points, the |^^^^abcd| notation is not used
+% since it causes error at compilation time in case if \LaTeX\ is running
+% and \texttt{utf8} input encoding is not declared.
+%
+% Note that two names for the Table of Contents can be used in Russian
+% publications. For books (and reports) the second variant is
+% appropriate, but for proceedings the first variant is preferred:

+% \subsection{Alphabetic counters}
+%
+% Do we need to reset |\@alph| and |\@Alph|? They are used in the
+% \LaTeX\ core to define the macros |\alph| and |\Alph|, respectively, which
+% type a counter with a corresponding letter of Latin alphabet.
+% We just want to make sure that correct |\latinencoding| is used instead of
+% |\latinencoding| to typeset the counter. Starting from v.1.2 we do not
+% reset these macros since all Cyrillic encoding but \texttt{X2} do have
+% Latin letters. When using the \texttt{X2} encoding user must himself
+% take care about selecting correct encoding when he switches his keyboard.
+% Our decision is motivated as follows. If selected Cyrillic font is visually
+% different from Latin font, the macro |\@alph| and |\@Alph| will produce
+% visually different output from surrounding text if they are used with
+% Russian text, which is completely legitimate.
+%
+% Notice for commented code:\\
+% We put |\latinencoding| in braces to avoid problems with
+% |\@alph| inside minipages (e.g., footnotes inside minipages) where
+% |\@alph| is expanded and we get for example `|\fontencoding OT1|'
+% (|\fontencoding| is robust).
+%
+% Note added on 2013/03/22: |{\fontencoding{\latinencoding}\selectfont|
+% rises an error with recent version of \pkg{microtype} package after the
+% |\appendix| declaration (which resets |\thechapter| to |\@Alph\c@chapter}|).
+% Most languages do not reset |\@alph| and |\@Alph| macros and only
+% \pkg{ukrainian} and \pkg{bulgarian} add |\fontencoding| to |\@alph| and
+% |\@Alph|.
+%
+% Since v.1.3 we do not reset |\@alph| and |\@Alph| here.
+% Resetting |\fontencoding| in |\@alph| and |\@Alph| causes an error
+% if the package |smartref| is loaded and a |\sref| occurs after the
+% |\appendix| declaration which resets |\thechapter| to |\@Alph\c@chapter|.

+%
+% As of version 1.2 the macros |\cyrmath..| are not supported any more. They

+% We also define few math operator names according to Russian typesetting
+% traditions. Some math functions in Russian math books have names
+% different from English writings. For example, \texttt{sinh} in
+% Russian is called \texttt{sh}. Special consideration needs the
+% macro |\th| that conflicts with the text symbol |\th|
+% defined in Latin~1 encoding:
+%
+% \changes{russianb-1.2}{2004/05/21}{Change definition of \cs{th}
+% only for this language}
+% \begin{macrocode}

+% Finally, we define some rare Russian mathematical symbols:
+% \begin{macrocode}
+\def\Prob{\mathop{\kern\z@\mathsf{P}}\nolimits}
+\def\Variance{\mathop{\kern\z@\mathsf{D}}\nolimits}
+\if@uni@ode

+ \def\NOK{\mathop{\cyrmathrm{\CYRN\CYRO\CYRK}}\nolimits}
+ \def\Proj{\mathop{\cyrmathrm{\CYRP\cyrr}}\nolimits}
+\fi
+% \end{macrocode}
+%
+% \subsection{Final settings}
+%
+% The macro |\ldf@finish| does work needed
+% at the end of each \file{.ldf} file. This
+% includes resetting the category code of the \texttt{@}-sign,
+% loading a local configuration file, and preparing the language
+% to be activated at |\begin{document}| time.
+%
+% \changes{russianb-1.1d}{1996/11/03}{Now use \cs{ldf@finish} to wrap
+% up}
