%  \section{Babel support for the Greek language}
%
%    The file \file{\filename}\footnote{The file described in this
%    section has version number \fileversion\ and was last revised on
%    \filedate. The original author is Apostolos Syropoulos
%    (\texttt{apostolo@platon.ee.duth.gr}), code from
%    \file{kdgreek.sty} by David Kastrup
%    \texttt{dak@neuroinformatik.ruhr-uni-bochum.de} was used to
%    enhance the support for typesetting greek texts.} defines all the
%    language definition macros for the Greek language, i.e.,
%    as it used today with only one accent, and the attribute
%    \Lopt{polutoniko} for typesetting greek text with all accents
%    (classical and polytonic Greek).
%
%  \DescribeMacro\greektext
%  \DescribeMacro\latintext
%    With 8-bit LaTeX, Greek text fonts use a non-standard font encoding
%    (LGR) that misses Latin letters. Latin characters in the source are
%    instead interpreted as a transcription for Greek symbols.
%    The commands |\greektext| and |\latintext| can be used to switch
%    to Greek or Latin font encodings but do not change the active language.
%    These are declarations.
%  \DescribeMacro\textgreek
%  \DescribeMacro\textlatin
%    The commands |\textgreek| and |\textlatin| both take one argument
%    which is then typeset using the requested font encoding.
%
%  \DescribeMacro\textol
%    The command |\greekol| switches to the greek outline font family,
%    while the command |\textol| typests a short text in outline font.
%    A number of extra greek characters are made available through the
%    added text commands |\stigma|, |\qoppa|, |\sampi|, |\ddigamma|,
%    |\Digamma|, |\euro|, |\permill|, and |\vardigamma|.
%
%  \subsection{Usage}
%
%    To activate Greek support with babel, specify the option
%    \Lopt{greek}, either as global option or as option to the
%    \pkg{babel} package. Remember, that the \emph{last} language
%    option determines the document language, e.g.
%    \begin{verbatim}
%    \usepackage[greek,english]{babel}\end{verbatim}
%    activates support for Greek in an English document while
%    \begin{verbatim}
%    \usepackage[english,greek]{babel}
%    \languageattribute{greek}{polutoniko}\end{verbatim}
%    sets the document language to Greek with ``polytonic''
%    spelling of auto-generated strings.
%
%    For backwards compatibility, ``polytonic'' spelling can also be
%    selected via the dummy language \Lopt{polutonikogreek}. In this
%    case, the language name \Lopt{polutonikogreek} must also be
%    used for language switches with |\selectlanguage| or
%    |\foreignlanguage|.  However, it is not possible to use
%    both options, \Lopt{greek} and \Lopt{polutonikogreek} in one document.
%
%  \subsubsection{Input of Greek text}
%
%    There are several alternatives for input of Greek text.
%    The required package \pkg{greek-fontenc} defines
%    \emph{LaTeX internal character representation} (LICR) macros
%    for Greek letters and text symbols.
%    With the packages \pkg{inputenc} and \pkg{greek-inputenc},
%    Greek characters can be input using the utf-8, iso-8859-7,
%    or macgreek encoding. The file \file{usage.pdf} explains a Latin
%    transliteration defined by the LGR font encoding.
%
%  \subsection{Greek numbering}
%
%    The Greek alphabetical numbering system, like the Roman one, is
%    still used in everyday life for short enumerations. Unfortunately
%    most Greeks don't know how to write Greek numbers bigger than 20 or
%    30. Nevertheless, in official editions of the last century and
%    beginning of this century this numbering system was also used  for
%    dates and numbers in the range of several thousands. Nowadays
%    this numbering system is primary used by the Eastern Orthodox
%    Church and by certain scholars. It is hence necessary to be able
%    to typeset any Greek numeral up to \hbox{999\,999}. Here are the
%    conventions:
%    \begin{itemize}
%    \item There is no Greek numeral for any number less than or equal
%      to $0$.
%    \item Numbers from $1$ to $9$ are denoted by letters alpha, beta,
%      gamma,  delta, epsilon, stigma, zeta, eta, theta, followed by a
%      mark similar to the mathematical symbol ``prime''. (Nowadays
%      instead of letter stigma the digraph sigma tau is used for number
%      $6$. Mainly because the letter stigma is not always available, so
%      people opt to write down the first two letters of its name as an
%      alternative. In our implementation we produce the letter stigma,
%      not the digraph sigma tau.)
%    \item Decades from $10$ to $90$ are denoted by letters iota,
%      kappa, lambda, mu, nu, xi, omikron, pi, qoppa, again followed by
%      the numeric mark. The qoppa used for this purpose has a special
%      zig-zag form, which doesn't resemble at all the original
%      `q'-like qoppa.
%    \item Hundreds from $100$ to $900$ are denoted by letters rho,
%      sigma, tau, upsilon, phi, chi, psi, omega, sampi, followed by the
%      numeric mark.
%    \item Any number between $1$ and $999$ is obtained by a group of
%      letters denoting the hundreds decades and units, followed by a
%      numeric mark.
%    \item To denote thousands one uses the same method, but this time
%      the mark is placed in front of the letter, and under the baseline
%      (it is inverted by 180 degrees). When a group of letters denoting
%      thousands is followed by a group of letters denoting a number
%      under $1000$, then both marks are used.
%    \end{itemize}
%
%    Using these conventions one obtains numbers up to \hbox{999\,999}.
%  \DescribeMacro{\greeknumeral}
%    The command |\greeknumeral| makes it possible to typeset Greek
%    numerals. There is also an
%  \DescribeMacro{\Greeknumeral}
%    ``uppercase'' version of this macro: |\Greeknumeral|.
%
%    Another system which was in wide use only in Athens, could
%    express any positive number. This system is implemented in
%    package |athnum|.
%
% \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{greek-1.0b}{1996/11/02}{Now use \cs{LdfInit} to perform
%    initial checks}
%    \begin{macrocode}
%<*code>
\LdfInit\CurrentOption{captions\CurrentOption}
%    \end{macrocode}
%    When the option \Lopt{polutonikogreek} was used, redefine
%    |\CurrentOption| to prevent problems later on.
%    \begin{macrocode}
\gdef\CurrentOption{greek}%
%    \end{macrocode}
%
%    When this file is read as an option, i.e. by the |\usepackage|
%    command, \texttt{greek} could be an `unknown' language in
%    which case we have to make it known.  So we check for the
%    existence of |\l@greek| to see whether we have to do
%    something here.
%
%    \begin{macrocode}
\ifx\l@greek\@undefined
  \@nopatterns{greek}
  \adddialect\l@greek0\fi
%    \end{macrocode}
%
%    Now we declare the |polutoniko| language attribute.
%    \begin{macrocode}
\bbl@declare@ttribute{greek}{polutoniko}{%
%    \end{macrocode}
%    This code adds the expansion of |\extraspolutonikogreek| to
%    |\extrasgreek| and changes the definition of |\today| for Greek
%    to produce polytonic month names.
%    \begin{macrocode}
  \expandafter\addto\expandafter\extrasgreek
  \expandafter{\extraspolutonikogreek}%
  \let\captionsgreek\captionspolutonikogreek
  \let\gr@month\gr@c@month
%    \end{macrocode}
%    We need to take some extra precautions in order not to break
%    older documents which still use the old \Lopt{polutonikogreek}
%    option.
% \changes{greek-1.3f}{1999/09/29}{Added some code to make older
%    documents work}
% \changes{greek-1.3g}{2000/02/04}{\cs{noextraspolutonikogreek} was

  \let\datepolutonikogreek\dategreek
  \let\extraspolutonikogreek\extrasgreek
  \let\noextraspolutonikogreek\noextrasgreek
  }
%    \end{macrocode}
%
%    Next, we check if Lua\LaTeX\ or Xe\LaTeX\ is running. If so, we set
%    boolean key |\if@babel@greek@unicode| to true.
%    (The test code is taken from russian.ldf. We hope that a future
%    version of \file{babel.sty} will do the check and provide a boolean.
%
%    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.
%
%    The test requires the e-TeX extensions (provided by all TeX engines in
%    contemporary TeX distributions).

%
%    Typesetting Greek texts requires a font containing Greek letters.
%    With the modern XeTeX or LuaTeX engines, the user should ensure that
%    the choosen font contains the required glyphs. Examples for suitable
%    fonts are the ``Deja Vu'' or the ``Linux Libertine'' OpenType fonts.
%
%    For 8-bit LaTeX, this package uses fonts with the LGR font encoding
%    (see the `greek-fontenc' package http://www.ctan.org/pkg/greek-fontenc).

%
%    Now we define two commands that offer the possibility to switch
%    to the LGR font encoding. Babel defines corresponding macros
%    to switch to a Latin font encoding.
%
%  \begin{macro}{\greektext}
%    The command |\greektext| will switch to
%    a Greek font encoding. This command is a \emph{declaration},
%    for shorter pieces of text the command |\textgreek| should be
%    used.
%    \begin{macrocode}
  \DeclareRobustCommand{\greektext}{%
    \fontencoding{LGR}\selectfont
    \def\encodingdefault{LGR}}
%    \end{macrocode}
%  \end{macro}
%
%  \begin{macro}{\textgreek}
%    This command takes an argument which is then typeset using the
%    requested font encoding. In order to avoid many encoding switches
%    it operates in a local scope.
% \changes{greek-1.0b}{1996/09/23}{Added a level of braces to keep

%    \begin{macrocode}
  \DeclareRobustCommand{\textgreek}[1]{\leavevmode{\greektext #1}}
%    \end{macrocode}
%  \end{macro}
%
%  \begin{macro}{\textol}
%    A last aspect of the set of fonts provided with this version of
%    support for typesetting Greek texts is that it contains an
%    outline family. In order to make it available we define the command
%    |\textol|.

  \DeclareTextFontCommand{\textol}{\outlfamily}
\fi  % End of LGR fixes not required with XeTeX/LuaTeX.
%    \end{macrocode}
%  \end{macro}
%
%    The next step consists in defining commands to switch to (and
%    from) the Greek language.
%
%  \begin{macro}{\greekhyphenmins}
%    This macro is used to store the correct values of the hyphenation
%    parameters |\lefthyphenmin| and |\righthyphenmin|.

%    The LGR encoded fonts that are used to typeset Greek with 8-bit TeX

%    \verb=|=. Therefore their |\lccode| is changed when Greek is in
%    effect. In order to let |\uppercase| give correct results, the
%    |\uccode| of these characters is set to a non-existing character

%    when typesetting ``modern'' $\mu o\nu o\tau o\nu

%  \begin{macro}{\greek@tilde}
% \changes{greek-1.0c}{1997/02/19}{Added command}
%    The Greek script uses a number of characters with more
%    than one accent. In LGR encoded fonts combined diacritics can be
%    obtained using Knuth's ligature mechanism (see usage.pdf).
%    Characters we need to have ligatures with are the tilde, the
%    acute and grave accent characters, the rough and smooth breathings,
%    the subscript, and the double quote character.
%    In text input the |~| is normally used to produce an

%    In order to get correct hyphenation we need to set the lower case

%    the end of a word and assures that a final sigma is typeset with
%    the proper sign wich is different from that of an initial or
%    medial sigma;  the  `v  'after  an  \textit{isolated} sigma fools
%    the ligature mechanism in order to typeset $\sigma$ in place of
%    $\varsigma$. Because of this we make sure its lowercase code is

%    For this to work we make the character |^^9f| a shorthand that
%    expands to nothing. In order for this to work we need to make a
%    character look like |^^9f| in \TeX's eyes. The trick is to have
%    another character and assign it a different lowercase code. The
%    execute the macros needed in a |\lowercase| environment. Usually
%    the tile |~| character is used for such purposes. Before we do
%    this we save it's original lowercase code to restore it once
%    we're done.
