% This extension package complements the greek option of the \babel\
% package so as to enable the use of the Lipsian\footnote{What here
% are called Lipsian fonts are a family of fonts that in Greece are
% called ``Lipsiakos''; they are similar to the ones that were being
% used in the Teubner Printing Company of Lipsia from mid XIX century on.}
% fonts and to use several macros for inserting special annotations
% in the written text, as well as to typeset verses with special
% layout. Metric sequences may be defined and typeset by means of a
% companion font \texttt{gmtr????} that follows the same conventions
% as the CB fonts that are normally used when the \babel\ greek
% option is in force.
%
% Examples and lists of commands are available in the file
% \texttt{teubner-doc.pdf} which, as a regular pdf file, embeds all
% the necessary fonts and may be read on screen as well as printed on paper;
% beware, though, that the PostScript fonts that are being used
% in \texttt{teubner-doc.pdf} are not distributed with the package.
% While this documentation is being written the \TeX{}-Live Team is trying
% to reduce the size of the distribution and one of the proposals is to reduce
% the number of Greek fonts distributed on \TeX-Live; therefore it might
% be necessary that the users of this \textsf{teubner} package download the
% missing fonts directly from one of the \acro{CTAN} archives.
% \end{abstract}
%
% \section{Introduction}
% Philologists in general have the necessity of using special
% alphabets and several special symbols in order to mark up their
% texts and to typeset them in a special way. Greek philology makes
% no exception, therefore I prepared this file and some extra fonts
% in order to complement what is already available with the greek
% option of the \babel\ package.
%
% I must warmly thank Paolo Ciacchi of the University of Trieste who
% invited me in this ``adventure'', since I know nothing about
% philology; he assisted me with all his competence, so that I
% could learn so many new things and I could appreciate the world of
% philologists.
%
% Paolo Ciacchi's ``invitation'' arrived when I was almost finished
% with the design of the Lipsian font family; I was working on this new
% typeface after a kind request of Dimitri Filippou, with whom I
% already collaborated for other questions related to Greek
% typesetting. I warmly thank also Dimitri Filippou for the
% patience with which he revised every single glyph of the new
% typeface. Paolo Ciacchi added his constructive criticism to the
% typeface, especially for what concerns diacritical marks. At the
% end I think that the new typeface turned out pretty well thanks to
% both my friends.
%
% The Lipsian font, also called Leipzig or Lipsiakos in Greece, is one of the
% oblique fonts that used to be employed by the typesetters working in the
% German city of Leipzig, among which the Teubner Printing Company.
% This Company's classical works of ancient Greek poetry are considered among
% the best ever published. The name of this file and this extension
% package is in honor of that printing company.
%
% This package documentation does not contain any example written in
% Greek, because when you process this file it is very likely that
% you don't have the suitable Greek fonts and you must still download
% all or some of them. Therefore a companion
% file \texttt{teubner-doc.pdf} is included in this bundle where most,
% if not all, the new commands are documented and suitably shown.
%
% This package contains new environments and new commands; it presumes
% the user invokes it after declaring the \texttt{greek} option to the \babel\
% package; should he forget, this package will complain. But once the
% \texttt{greek} option is properly declared, this package verifies that the
% |polutonikogreek| dialect is selected, or that the |polutoniko| attribute
% is set. This choice depends on the particular version of the \babel\
% package, but should not concern the user; switching back and forth
% between classical Greek and some modern western language is performed
% in a transparent way; possibly there might be some problem switching
% from classical to modern spelling in Greek itself, but since in modern
% spelling the multiplicity of Greek diacritical marks is not forbidden,
% it's the author choice to select classical or modern words, Lipsian or
% Didot fonts, polytonic or monotonic accentuation. The worst it can happen
% is that \babel\ might use just one hyphenation pattern set, so that in
% one of the two Greek versions some words might turn out with the wrong
% hyphens.
%
% The CB Greek fonts, which have been available for some years now on
% \acro{ctan} in the directory \texttt{/tex-archive/fonts/greek/cb} have
% been completed with the new files for the Lipsian fonts, and the metric
% symbols font \texttt{gmtr????.*}; 
% the latter does not need a formal font definition file, because
% the necessary definitions are included in this package.
% All fonts are available also as Type~1 scalable fonts. In general, recent
% distributions of the \TeX\ system already contain the necessary
% configuration to use the Type~1 font in one size, 10\,pt, but, thanks
% scaling, these can be used at any size; this version of \textsf{teubner}
% is compatible with this reduced set. If optical sizes are desired for
% a more professional typesetting, the \acro{ctan} archives contain also
% the \textsf{cbgreek-full} package, which includes also all the Type~1
% fonts at the various standard (EC) sizes, plus other facilities that allow
% to use the CB fonts also in conjunction with the Latin Modern ones.
%
% The CB Greek fonts allow to input Greek text with a Latin keyboard and
% by employing the prefix notation; with a Greek keyboard and file
% \texttt{iso-8859-7.def} it is possible to directly input Greek text with the
% monotonic spelling; if polytonic spelling is required I fear that the above
% file is of little help and that a Latin keyboard does the job without
% an excessive burden.
%
% Nevertheless there is a little point to observe; Lipsian fonts are very
% nice but show most kerning errors with more evidence than the traditional
% Didot Greek fonts. With the prefix notation in force, kerning programs may result disabled
% and some diphthongs and some consonant-vowel combinations appear poorly matched when
% the second letter caries any diacritical mark. In order to avoid this
% ``feature'', the accented vowels may be input by means of macros, that
% directly translate to the accented glyph, rather than invoking the ligature
% programs that are implied by the prefix notation; reading a Greek text
% on the screen while editing the input \texttt{.tex} file when a Latin
% keyboard and such macros are used may be very strange, but authors get
% used to it, and agree that the effort is worth the result.
%
% \section{Environments}
% I apologize if I chose Italian names for verse environments; I wanted to
% use names very different from the corresponding English ones, but at the
% same time easily recognizable; after all \emph{versi} is the plural of
% \emph{verso} and therefore is the exact Italian translation of \emph{verses}.
% If you feel more comfortable with Latin the alias environment names
% in Latin, |versus|, |Versus|, and |VERSUS|, are also available.
%
% \DescribeEnv{versi}
%\DescribeMacro{\verso} 
% The environment \texttt{versi} (|versus|) is used to typeset verses
% in line, without an implicit end of line at the end of each verse; a vertical bar
% with a number on top of it marks the verse limit while allowing a numeric
% reference to a specific verse; the opening environment statement requires
% a string, a short text, in order to indent the verse lines the amount of
% this string width; the syntax is the following
% \begin{sintassi}
% \bslash begin\lbr versi\rbr\lbr\meta{string}\rbr{}
% \meta{verse}\bslash verso[\meta{starting number}]\meta{verse}\bslash verso
% \meta{verse}\bslash verso\meta{verse}\dots{}
% \bslash end\lbr versi\rbr
% \end{sintassi}
% where, of course, \meta{starting number} is required only for the first
% instance of |\verso| or when numbering must be restarted, for example
% after an ellipsis.
%
% \DescribeEnv{Versi}
% The environment \texttt{Versi} (|Versus|) is similar to the
% standard \LaTeX\ environment \texttt{verse}, except verse lines are numbered
% on multiples of~5; the opening statement requires the \meta{starting
% number} as an optional argument; if this optional argument is not specified,
% the starting number is assumed to be~1.
% \begin{sintassi}
% \bslash begin\lbr Versi\rbr[\meta{starting number}]
% \meta{verse}\bslash\bslash{}\meta{*}[\meta{vertical space}]
% \meta{verse}\bslash\bslash{}
% \dots{}
% \bslash end\lbr Versi\rbr
%\end{sintassi}
%
% \DescribeEnv{VERSI}
% \DescribeMacro{\SubVerso}
% \DescribeMacro{\NoSubVerso}
% The environment \texttt{VERSI} (|VERSUS|) allows for two verse
% enumerations; the main enumeration is identical to the one performed by
% the previous environment \texttt{Versi}, while the secondary enumeration
% is in smaller digits and normally numbers consecutive verses, except
% that it can be turned on and off; the verses that lack the secondary
% enumeration are indented by moving them to the right.
% \begin{sintassi}
% \bslash begin\lbr VERSI\rbr[\meta{starting principal number}]
% \meta{verse}\bslash\bslash\meta{*}[\meta{vertical space}]
% \bslash SubVerso[\meta{starting secondary number}]
% \meta{verse}\bslash\bslash\meta{*}[\meta{vertical space}]
% \dots{}
% \bslash NoSubVerso
% \meta{verse}\bslash\bslash\meta{*}[\meta{vertical space}]
% \dots
% \bslash end\lbr VERSI\rbr
% \end{sintassi}
% where if \meta{starting principal number} is missing, 1 is assumed,
% while if \meta{starting secondary number} is missing, the enumeration
% is continued from the next available integer. Of course
% \meta{starting secondary number} is used again when the secondary
% enumeration must be restarted; there are no means to restart the
% principal enumeration.
%
% \DescribeEnv{bracedmetrics} The previous environments accept \meta{verses}
% in any language and in any alphabet, the one that is in force before opening
% the environment; the language and, even less, the alphabet cannot be
% globally changed within the above environments; if such a change is performed,
% it is valid only for one verse, or for the remaining fraction of the verse
% after the language or font change. This means, among the other things, that
% if the default ``alphabet'' is the one that shows the metric symbols,
% the above environments may be used to display ``metric verses'', that is the
% pattern of long, short or ancipital symbols, together with any other metric symbol
% so as to display the metrics without disturbing the written text; when doing
% this metric typesetting, it may happen that some verse patterns exhibit some
% variants; in this case the \texttt{bracedmetrics} environment comes handy, because
% it can display such variants in separate lines but grouped with a large right
% brace; some commands allow to roughly align these variants, so as to
% allow to nest several such environments as if they were single blocks of metric
% symbols. The argument of the opening statement specifies the width of the
% block so as to align properly all the symbols even in nested environments.
% \begin{sintassi}
% \bslash begin\lbr bracedmetrics\rbr\lbr\meta{length}\rbr{}
% \meta{metric pattern}\bslash\bslash
% \meta{metric pattern}\bslash\bslash
% \dots{}
% \bslash end\lbr bracedmetrics\rbr
% \end{sintassi}
% \DescribeMacro{\verseskip}\DescribeMacro{\Hfill} Within the \meta{metric pattern}
% it is possible to flush right the symbols
% by prefixing the whole string with a |\Hfill| command; the \meta{length} may
% be specified as an integer multiple of a ``long'' symbol by means of
%\begin{sintassi}
% \bslash verseskip\lbr\meta{number}\rbr
%\end{sintassi}
% The macro |\verseskip| can be used also within \meta{metric pattern}
% in order to space out metric symbols.
%
% \section{Commands and symbols}
% This package defines a lot of commands for inserting special signs in the middle
% of regular text, for marking zeugmas and synizeses, for putting unusual accents
% on any symbol, for inserting special ``parentheses'' that are used by philologists
% for marking blocks of letters or blocks of text. I suggest that the user consults
% the documentation file \texttt{teubner-doc.pdf} for a complete list of commands
% and symbols.
%
% \DescribeMacro{\newmetrics} Here it might be useful to describe a command
% for defining metric sequences, so as to shorten the definition of metric verses;
% this new command is |\newmetrics| and may be used for the definition of new
% commands whose name \emph{may start with one digit}: precisely this digit may be
% one of~2, 3,~4. Even if \LaTeX\ does not allow macros to contain both digits
% and letters, other service macros have been defined so as to handle these
% special control sequences even if they start with \emph{one} digit strictly lower
% than~5. The syntax is:
% \begin{sintassi}
% \bslash newmetrics\lbr\meta{control sequence}\rbr\lbr\meta{definition}\rbr
% \end{sintassi}
% where \meta{definition} consists in general of a sequence of metric commands such
% as |\longa|, |\brevis|, |\anceps|, etc.
%
% \section{Acknowledgements}
% I must thank with gratitude Paolo Ciacchi that urged me to prepare this extension
% file in order to help him typeset his master thesis of philological type in
% classical Greek.
%
% I am pleased to thank G\"unter Milde who wrote a definition file for accessing the
% LGR encoded fonts in order to fetch the accented glyphs; I kindly gave me
% permission to use his macros, that I adapted to the conventions used within this
% file. These macros are saved into the definition file |LGRaccent-glyph.def|, so that it can be used also without the |teubner| package, fore example for typesetting without setting the \emph{polytoniko} language attribute.
%
% I got some ideas also from a paper that Werner Lemberg published on Eutypon, the
% magazine of the Hellenic Friends of \TeX, where he discussed in a constructive
% critical way the problems connected with the LGR encoded fonts and the Unicode
% encoding.

% The beginning of the file starts with the traditional stuff;
% as usual we provide also the means for avoiding reading this file again.

% In order to use the PostScript pfb fonts (CM, EC, and CB) it is necessary to know
% if we are dealing with \LaTeX\ or pdf\LaTeX; this was necessary because apparently
% the pfb math scalable fonts derived from the \textsf{META\-FONT} counterparts do
% not have exactly the same effective dimensions; this is why the ``zeugma'' and the
% ``synizesis'' signs have to be corrected when the pfb fonts are used; with these,
% in facts, the black leader that joins the curved extremities appeared a little too
% fat and did not join exactly the left mark. Recently, apparently, the fonts have
% been corrected and this trick is not necessary any more. Nevertheless  we define
% a new boolean that copes with the fact that sin 2007 the \TeX\ engine is
% \textsf{pdftex} even when DVI output is sought:
%    \begin{macrocode}
\newif\ifPDF \PDFfalse
\@ifundefined{pdfoutput}{\PDFfalse}{\ifnum\pdfoutput>\z@\PDFtrue\fi}
%    \end{macrocode}
% When \texttt{teubner.sty} is input the language Greek must have been already
% defined; otherwise an error message is issued and processing is terminated.

\fi
%    \end{macrocode}
% If this test is passed, this means that not only the greek option to the \babel\ 
% package is set, but also that all the \babel\ machinery is available.
%
% Since \texttt{teubner.sty} accepts some options it is necessary to provide
% their definitions; in particular the |\or| control sequence conflicts
% with the |\or| primitive command used within the syntax of |\ifcase|\footnote{With
% version 2002/07/18 v.1.0d this has been eliminated; the option remains for
% compatibility with older versions, but the only legal command is now
% \texttt{\string\oR}.}; |\oR| is a little exception since all the other
% accent-vowel macros contain only lowercase letters. The point is that accent vowel
% sequences that directly access the accented glyph are made up as such:
% \begin{sintassi}
% \bslash \meta{base character}\meta{first diacritic}\meta{second diacritic}%
% \meta{third diacritic}
% \textrm{where}
% \meta{first diacritic} \textrm{is \texttt{d} or \texttt{r}  or \texttt{s} for
% diaeresis, rough or smooth breadth}
% \meta{second diacritic} \textrm{is \texttt{c} or \texttt{a} or \texttt{g} for
% circumflex or acute or grave}
% \meta{third diacritic} \textrm{is \texttt{i} for iota subscript or adscript}
% \end{sintassi}
% Evidently none of the diacritical marks is compulsory, but at least one must
% be present; if more than one is present it must be given in that sequence. Since
% |\oR| means omicron with rough breath, it is not very important that it is
% declared with the standard sequence |<o| or with |\oR|, because it never
% falls after another letter, so that it never breaks any ligature or kerning
% command. The command is there just for completeness.
%
% At the same time since all accent combinations are defined as ``text commands'',
% in \LaTeX\ jargon, when their commands are followed by a vowel (or `r') they
% define a ``text symbol'' i.e.\ they fetch directly the glyph of the accented
% character; therefore |<o|, |\oR| and |\r{o}| are all equivalent (at the beginning
% of a word where omicron with rough breath is the only place where you can find
% it). See more on this point in the sequel.
%
% Nevertheless, while these glyph name macros are defined by default, it is possible
% to do without by specifying the option \emph{NoGlyphNames}, In this case the same
% result is more comfortably obtained by using the extended accent macros whose
% behaviour is specified in the definition file |LGRaccent-glyph.def|.
%
% Another unusual option is set up for being used with non standard \TeX\ system
% fonts; we have noticed that the Lipsian fonts appear a little too light when used
% together with the Times or the Palatino fonts; probably this is true also with
% other PostScript fonts. In this case the user might specify the option
% |boldLipsian| and the Lipsian fonts used in medium series will be substituted
% with those of the semi\-bold one. 
%
% At the same time, from July 2005, The full collection of the complete size set of
% the CB fonts is not available any more \emph{as the default \TeX\ system set up};
% only the 10pt size are available unless the \texttt{cbgreek-full} font package is
% loaded; for this reason a new option is needed in order to instruct
% \texttt{teubner.sty} to use the specific file \texttt{type1ec.sty} dated at least
% 2002/09/07, so as to scale up or ddown all the EC and CB fonts from an original
%  10\,pt size. In order that the \texttt{10pt} plays its role correctly, it is
% convenient, if not compulsory, to require first the \texttt{babel} package, then
% the \texttt{teubner} one with the option \texttt{10pt}, then all other packages
% required for a specific document, in particular the \texttt{fontenc} one if the
% \texttt{T1} encoding is requested.
%
% This kludge is necessary for all fonts that have description files that use the
% |\EC@family| command for describing the available shapes and sizes; in practice
% this happens only with the EC fonts, even when the \texttt{cm-super} scalable
% implementation is used. For using the Latin Modern fonts (LM) new specific font
% description files for the CB fonts are part of the \babel\ package, so this
% problem does not exist; when using other fonts, such as the TX, PX, ZE,~\dots,
% other kludges are necessary, because their font family names are different from
% those normally used with \TeX: |cmr| for serifed fonts, |cmss| for sanserif ones,
% and |cmtt| for monospaced ones.\footnote{Even the Latin Modern fonts have
% different family names, but, due to their importance, specific font description
% files have been added to the \babel\ package. The Lm fonts are more comfortable
% than the EC ones, when scalable fonts are to be used, because they are
% continuously scalable and download into the produced files less font files than
% the EC o cm-super ones. Unless specifically requested, the LM fonts should always
% be preferred to the EC and cm-super ones. When using the LM fonts, its better to
% use the full collection of the CB fonts, although the CB font description files
% are compatible with the single 10\,pt size.}
%
% Notice that when using, for example, the TX fonts and no kludge is available, the
% CB fonts are loaded only as the ``error font'', since the TX fonts have different
% family names than the CB ones; in many cases this might pass un-noticed, but if
% real Greek text in different shapes and series has to be typeset, the unaware
% typesetter might get crazy trying to force shape and series changes in the Greek
% text; it would not be impossible, but it would be very, very boring. In any case
% see in the sequel for the implemented kludges in order to run successful
% compilations also with non standard \TeX\ system fonts.

% In the sequel we frequently use the acronym for the Greek font encoding; we hope
% it will eventually become \texttt{GR} or, following the actual 256 glyph font
% encodings, \texttt{T7} or \texttt{X7}\footnote{Apparently \texttt{T7} has been
% chosen to define an encoding where the first 128 glyphs are the standard
% \texttt{OT1} encoded Latin fonts, and the second group again of 128 glyphs
% contains the Greek characters; therefore, since polytonic spelling requires more
% than 128 glyphs, the extended encoding \texttt{X7} will probably become the one
% applicable to the whole set of the CB fonts.}.
% Meanwhile the acronym is \texttt{LGR}, so we'd better define a symbolic name, so
% that we can change the definitive name in just one place.

%\begin{macro}{\previouslanguage}
%\begin{macro}{\previousencoding}
% The ``default'' language is defined as the
% ``previous'' language; similarly the ``default'' encoding is defined as the
% ``previous'' encoding; these are the language and the encoding in force when the
% document starts; this is why such macros are defined at the beginning of the
% document. At the same time we assure that if the CM (or EC) or the LM fonts are
% the default ones, nothing special is done, while if the default fonts are, say,
% the TX ones, they are correctly restored, but the CM families are used for the CB
% ones. 
%\end{macro}
%\end{macro}
%
%\begin{macro}{\substitutefontfamily}
%\begin{macro}{\ifLipsian}
% The font macro |\substitutefontfamily| is already present in the \babel\ kernel;
% I copes only with the standard families, series and shapes, therefore it does not
% consider the Lipsian shape and its series. I had to redefine it together with a
% new conditional macro in order to do the same job as the original one but taking
% into consideration also the Lipsian shape; the purpose of this macro is to write
% in the working directory a number of font description files that refer to the LGR
% Greek encoding, but have the names of the Latin font families; such font
% description files, simply substitute these non existent encoding-family series and
% shapes with the existing series and shapes of any other LGR encoded Greek font, in
% particular the CB ones. By issuing a command such as:
% \begin{sintassi}\ttfamily
% \texttt{\string\ifFamily}\{pxr\}\{cmr\}
% \end{sintassi}
% an association is made with all the series and shapes of the Palatino serifed
% fonts to the corresponding CB serifed series and shapes; therefore when a language
% shift changes the default encoding from, say, \texttt{T1} to  \texttt{LGR} the
% font family \texttt{LGR+pxr} is mapped to the font family \texttt{LGR+cmr} and
% everything is supposed to work fine; when another language change resets the
% encoding to \texttt{T1}, the original Latin script is used again. The redefined
% |\substitutefontfamily| macro is as such:

% Notice that together with the Lipsian fonts the upright italics (Olga) and upright

% wanted\dots
%
% These results are obtained by means of the following macros.
%\begin{macro}{\ifCMLM}
%\begin{macro}{\ifFamily}
% The |\ifCMLM| processes the necessary test in order to set the auxiliary macro
% |\n@xt| to be an alias to |\iftrue| or |iffalse| depending on the fact that the
% CM (or EC) fonts or the LM fonts are the default Latin ones, in this case it sets
% the |\n@xt| macro equivalent to |\iftrue|, otherwise it sets it to |\iffalse|. In
% order to succeed, it requires to analize the first two letters of the default
% family name; if these letters form one of the sequences |cm| or |lm|, the CM or
% LM fonts have been loaded, otherwise some other fonts are in force. We need
% therefore a macro with delimited arguments in order to extract the ffirst two
% letters of the family name.
%
%    \begin{macrocode}
\def\ifCMLM#1#2#3!{\edef\f@milyprefix{#1#2}%
   \ifthenelse{\(\equal{\f@milyprefix}{cm}\OR\equal{\f@milyprefix}{lm}\)}%
   {\let\n@xt\iftrue}{\def\f@milyprefix{cmr}\let\n@xt\iffalse}\n@xt}
   
%    \end{macrocode}
% The other macro |\ifFamily| uses the previous macro and according to the test
% result, possibly runs the |\substitutefontfamily| macro that, if
% necessary, creates the description file that map the specified family font
% description file to the second specified font family, both connected to the LGR
% encoding. Therefore, after these font definition files exist, \LaTeX\ can fetch
% the Greek fonts by way of substitution. Let's explain again: if you specify
% \begin{verbatim}
% \Lispsiantrue\ifFamuly{pxr}{lmr}\Lipsianfalse
% \end{verbatim}
% you state that you want to run the macro on the serifed Palatino font family, by
% associating the |pxr| family to the |lmr| one\footnote{If you have the full CB
% Greek font collection it's more convenient to map the missing fonts to the Latin
% Modern Greek ones, while if you need to use the \emph{10pt} option, you'd better
% map the missing family to the ordinary Computer Modern ones; the actual fonts are
% the same, but the latter font definition files cope with the \emph{10pt} option,
% while the former don't.}; by specifying |\Lipsiantrue| you state that you want to
% create entries also for the Lipsian series and shape; afterwards you reset
% |\Lipsianfalse| in order to avoid that other call of that macro on non serifed or
% monospaced fonts try to create entries that in any case do not exist: the Lipsian
% font comes only as a serifed font!. In this way, if you are using Palatino fonts
% through the \textsf{pxpackage}, the |teubner| macros provide to create the
% necessary font description files so that while you are typesetting in medium
% normal Latin Palatino and you switch to Greek, the built in macros change the
% encoding to LGR; The LGR Palatino serifed medium normal Greek font does not exist,
% but that family, series and shape are mapped by the font description file to the
% corresponding LGR encoded Latin Modern CB fonts in medium series and normal shape,
% and typesetting goes on with the rigth Greek fonts.
%    \begin{macrocode}
\newcommand*\ifFamily[2]{% 
\expandafter\ifCMLM#1!\else\substitutefontfamily{LGR}{#1}{#2}\fi}

%    \end{macrocode}
% You don't actually need to use that macro for the Times or the Palatino eXtended
% fonts loaded by means of the corresponding packages \textsf{txfonts} or
% \textsf{pxfonts}, because a hook is set up so that ``at begin document'' the
% loading of those packages is tested, and if the test is true, the necessary font
% description files are possibly created. If you load the Tymes or the Palatino or
% any other non standard font by means of other packages, it's up to you to issue
% the |\substitutefontfamily| macro right after calling that font package and by
% using the correct family names; similarly you might substitute the new Latin font
% family names to other Greek font family names, if you have other fonts available.
% At the same time at begin document we memorize the name and encoding of the Latin
% font used for the default language, so that when returning to Latin font
% typesetting after Greek font typesetting, the proper language typesetting rules
% and encoding are restored.
%    \begin{macrocode}

%    \end{macrocode}
% Nevertheless all this requires a minimum of attention in specifying the options
% for the \babel\ package and in the order extensions packages are read in. The
% |teubner.sty| package should be read \emph{after} any other package that sets or
% resets the Latin  font encoding; for example if
% the T1 encoding is selected as the default one, in place of the OT1 encoding, then
% this choice must be made before this package is read in. Similarly when the
% \babel\ options are specified, remember that the last language name becomes the
% default language at begin document; never specify \texttt{greek} as the last
% language option!

%\begin{macro}{\Lipsiakostext}
%\begin{macro}{\lishape}
%\begin{macro}{\textli}
% |\lishape| is the normal declaration, modeled on the other similar macros in the

% light character, if it must blend well with the other PostScript fonts, not only
% the CM and LM, but also the other ones available for typesetting with the \TeX\ 
% system, it is necessary to chose the |b| (bold) series in place of the |m|
% (medium) one, while maintaining the |bx| (bold extended) series when the other
% fonts are set with the blacker and larger series. This is why the |\lishape|
% declaration is a little more complicate than normal, since it has to test the
% value of the current series. The text command |\textli| matches the similar
% commands for Latin fonts. But the |\lishape| declaration is used also within the
% more complicated macros for declaring or setting the Lipsian font.
%
% |\Lipsiakostext| is a \emph{declaration} stating that from now on
% typesetting will be done with the Lipsian fonts; notice that the encoding and the

% \subsection{Service macros}
% Now we start the specific additions introduced with this package.
%
% \begin{macro}{\strip@pt}
% The \LaTeX\ kernel has the macro |\strip@pt| that strips off the pt part from the
% expanded value of a dimension register name and makes available the measure in pt
% of the contained length (the register contains the length measure in scaled
% points; the expansion performed by \TeX\ with the command |\the| converts the
% scaled points to printer points and shows the result with a string of decimal
% digits with, possibly, a decimal fraction); its argument is supposed
% to be a dimension register name, not its expanded contents. The |\strip@pt|
% command eliminates the decimal point and the fractional part if the latter is
% nought.
% With the help of such service macro we are going to define a certain number of
% ``lift accent'' macros or ``put cedilla'' macros that work with both upright and
% slanted fonts, although they contain different parameters for Latin compared to
% Greek alphabets.
% \end{macro}
%
% \begin{macro}{\lift@accent}
% The first ``lift accent'' macro just puts an accent over
% a letter, without inserting any space between them; the first argument is the
% accent code (decimal, hexadecimal or octal; I prefer decimal), while the second
% argument is the letter --~any letter, even if it is not a vowel!
% \begin{macrocode}

%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\LIFT@accent}
% The third ``lift accent'' macro behaves as the first one, except it interposes a
% specified vertical space between the letter and the accent; this space is
% specified as the second argument:
% \begin{macrocode}
\newcommand*\LIFT@accent[3]{\leavevmode

%    \end{macrocode}
% \end{macro}
%
% All these macros will be used in subsequent ``put accent'' macros, that will
% stack also several accents one above the other; the necessity arises for example
% when the macron or breve diacritical marks have to be put over accented letters;
% according to typographical practice the accents must go over the macron or the
% breve.
% In a similar way philologists often must use other diacritical marks in addition
% to the traditional Greek ones, therefore these macros will be used, for example,
% for setting the Scandinavian ring (from a Latin font) over a Greek letter (from a
% Greek font).
%
% \begin{macro}{\cap@}
% The first such unusual diacritical mark is a small cap, a small upside down breve
% sign, that is in position~1 of the Greek font table.
% \begin{macrocode}
\DeclareRobustCommand{\cap@}[1]{\leavevmode
{\edef\slant@{\strip@pt\fontdimen1\font}%

\raise\@tempdima\hbox to\z@{\kern\dimen@\box\tw@\relax\hss}\box\z@}}

%    \end{macrocode}
% The |\ifx\cf@encoding\GRencoding@name| conditional construct shows that this
% macro behaves differently with different font encodings; the following |\ifx#1k|
% checks the argument against the Greek letter kappa, which shows very clearly
% that these macros operate on any letter, not only on vowels.
% \end{macro}
%
% \begin{macro}{\cap}
% By means of the above |\cap@| macro we can define three equivalent commands to be
% used either when the Greek encoding is in force, or when one of the Latin
% encodings is in force:
%    \begin{macrocode}
\DeclareTextCommand{\cap}{\GRencoding@name}{\cap@}
\DeclareTextCommand{\cap}{OT1}{\cap@}
\DeclareTextCommand{\cap}{T1}{\cap@}

%    \end{macrocode}
% Probably one definition would be sufficient, but on one side the presence of three
% encoding dependent macros are the remains of initial works, while on the other
% side they prevent to use these macros with encodings for which the macro might not
% work well, because it was not tested with them.
% \end{macro}
%
% \begin{macro}{\cap@cedilla}
% Similarly a small cap can be put under another letter as it was a cedilla; for
% this task another macro is defined, which makes use of the same glyph in
% position~1 in the Greek font table:
% \begin{macrocode}
\newcommand*\cap@cedilla[1]{\leavevmode

\fi
\hbox to\z@{\kern\dimen@\box4\hss}\unhbox\z@}}

%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\ring@cedilla}
% Another cedilla like diacritical mark is the Scandinavian ring put under a letter;
% the ring is taken from the metrics font, so its slot position does not depend 
% on the various  Latin encodings; the correct positioning requires careful
% examination of the letter under which it is to be placed, distinguishing the Greek

% \subsection{Extended accent definitions}
% We will use those service macros in the definition of several accent like macros
% that keep all the intricacies away from the user. Meanwhile we input from
% a separate file |LGRaccent-glyph.def| a whole set of extended accent macros
% slightly adapted from those contained in G\"unter  Milde's definition file.
% In particular the \LaTeX\ kernel macros are used in order to declare accents,
% composite glyphs, composite commands, and the like; these are used as the default
% definitions; afterwards other definitions will be given that work when these
% composite macros don't work.
% In other words, while |\~| and |u| in Greek form the composite glyph ``upsilon
% with circumflex'' that exists in the Greek font table, the same macro |\~| and the
% letter |k| produce the  superposition of a circumflex on top of a ``kappa'' glyph,
% since this glyph does not exist in the Greek font table.
% Notice that all these declarations are restricted to the Greek font encoding so
% they are usable only when such font is in force. See the |teubner-doc.pdf| file
% for more details concerning the usefulness of the extended accent macros vs.\ the
% ligature mechanism.
% 
%    \begin{macrocode}
\input{LGRaccents-glyphs.def}
%    \end{macrocode}
%
% \subsection{Special accent macros}
% Now we come back to the ``accent like'' and ``cedilla like'' general macros we
% defined above, and that  will be extensively used in the following definitions.
% Note that for what the circumflex is concerned, when |teubner| is in effect it is
% not defined as an active character and does not work as a non breaking space. The
% command |\~| and its equivalent |\GRcirc| is just an accent macro; how do you put
% a non breaking space in a Greek context? By simply using the \LaTeX\ kernel macro
% |\nobreakspace|; when typesetting with non-Greek fonts the |~| is certainly handy
% to insert a non breaking space (a tie), but for polytonic Greek spelling in the
% past 15 years or so the Greek language definition file has always used the |~|
% sign a a letter, not as an active character. If you look in the \babel\ package
% documentation related to the Greek language, you find that for what concerns the
% |~| with polytonic spelling a number ot ``dirty tricks'' have been used, but
% nothing has been done to replace the ``tie'' function of this character when
% typesetting in languages that use the Latin script; the only action related to
% this point has been to redefine the kernel macros for typesetting figure and table
% captions so as to substitute the |~| character with its explicit definition
% |\nobreakspace|. It is necessary to do the same when this package is used,
% although a shorter command |\nbs| is provided in order to simplify the input
% keying.
%    \begin{macrocode}
\let\nbs\nobreakspace
%    \end{macrocode
%
% Having defined the Greek accents with the extended macroso input with the 
% |LGRaccents-glyphs.def| file, we can let some equivalences so that such accents
% may be used with shorter control sequences that are coherent with the
% corresponding ligatures.
%    \begin{macrocode}
% grave
\DeclareTextCommand{\`}{\GRencoding@name}[1]{\lift@accent{96}{#1}}
% acute
\DeclareTextCommand{\'}{\GRencoding@name}[1]{\lift@accent{39}{#1}}
% circumflex
\DeclareTextCommand{\~}{\GRencoding@name}[1]{\lift@accent{126}{#1}}
\let\GRcirc\Perispomeni

%    \end{mcrocode}
% But we have to provide also the means for disabling the |~| shorthand that is
% reset every time the Greek language is selected again in a multilanguage document
% where language shifts take place quite often; we must also counteract the
% resetting of the |\~| definition performed by the |greek.ld| file in every
% language shift; it is not important to add the accent re-definition to the 
% |\extrasgreek| macro, because when this macro is executed the last definition
% given is the one that lasts until the next language shift.
%    \begin{macrocode}
\addto\extrasgreek{\shorthandoff{~}\let\~\Perispomeni}
\addto\noextrasgreek{\shorthandon{~}}

%    \end{macrocode}
% For the diaeresis we need to put an invisible character (|v| in the LGR encoded CB
% fonts) in order to avoid any ligature with an implied end of word (boundarychar)
% that turns the diaeresis into an apostrophe.
%    \begin{macrocode}
% diaeresis
\DeclareTextCommand{\"}{\GRencoding@name}[1]{\lift@accent{34v}{#1}}
% breve
\DeclareTextCommand{\u}{\GRencoding@name}[1]{\lift@accent{30}{#1}}
%    \end{macrocode}
% Besides the normal |\u| command for setting a breve command, another ``large
% breve'' is required by philologists, who need to mark a diphthong, or in general
% two letters; the macro |\U| does the job, but it is the typesetter's
% responsibility to input the macro argument as made of two letters (possibly with
% their own accents):
% \begin{macrocode}
\DeclareTextCommand{\U}{\GRencoding@name}[1]{\lift@accent{151}{#1}}
% macron
\DeclareTextCommand{\=}{\GRencoding@name}[1]{\lift@accent{31}{#1}}
% rough
\DeclareTextCommand{\r}{\GRencoding@name}[1]{\lift@accent{60}{#1}}
% smooth
\DeclareTextCommand{\s}{\GRencoding@name}[1]{\lift@accent{62}{#1}}
% acute+diaeresis
\DeclareTextCommand{\Ad}{\GRencoding@name}[1]{\lift@accent{35}{#1}}
% grave+diaeresis
\DeclareTextCommand{\Gd}{\GRencoding@name}[1]{\lift@accent{36}{#1}}
% circumflex+diaeresis
\DeclareTextCommand{\Cd}{\GRencoding@name}[1]{\lift@accent{32}{#1}}
% acute+rough
\DeclareTextCommand{\Ar}{\GRencoding@name}[1]{\lift@accent{86}{#1}}
% grave+rough
\DeclareTextCommand{\Gr}{\GRencoding@name}[1]{\lift@accent{67}{#1}}
% circumflex+rough
\DeclareTextCommand{\Cr}{\GRencoding@name}[1]{\lift@accent{64}{#1}}
% acute+smooth
\DeclareTextCommand{\As}{\GRencoding@name}[1]{\lift@accent{94}{#1}}
% grave+smooth
\DeclareTextCommand{\Gs}{\GRencoding@name}[1]{\lift@accent{95}{#1}}
% circumflex+smooth
\DeclareTextCommand{\Cs}{\GRencoding@name}[1]{\lift@accent{92}{#1}}
%    \end{macrocode}
% Most of the above accent commands are used again in order to tie a text symbol
% meaning to certain combinations, that is when they receive as argument a vowel
% whose accented glyph is present in the font; in this way in order to type
% ``alpha with rough breath, acute accent and iota subscript'' you can type
% \verb"<'a|", or \verb"\Ar{a}|" or |\arai| or \verb+\<'a|+, if you use Milde's
% accent macros; the advantage of using the first notation is its short string; the
% advantage of the second is that it does not break kerning commands with a
% preceeding letter; the advantage of the third is that it does not break any
% kerning either before or after; the fourth solution produces the same result as
% the third, but it's easier to make up and you don't have to memorize any specific
% naming rule for accented glyphs. With the Lipsian font this trick is particularly
% useful for any sequence of alpha and upsilon each one with its own accents and/or
% diaresis.
%
% In Greek the regular cedilla is meaningless, so that |\c| may be redefined
% as a semivowel command; at the same time the typesetter might be more
% comfortable if he could use always the same, although longer, macro for
% marking a vowel as a semivowel one; therefore |\c| plays the same role

% \subsection{Accent macros and glyph names}
% Now come dozens of macros that allow to access Greek accented vowels (plus rho
% with rough and smooth breaths) with macros instead of ligatures; such macros allow
% the kerning information to be used by \TeX, while the ligature mechanism would
% sometimes impeach the use of such kerning information. Notice that the same glyphs
% are often accessed with a ``text symbol'' or a ``text composite symbol''; as
% explained above the opportunity of using either one derives from the necessity of
% maintaining the kerning mechanism embedded in the font; if the CB fonts had a
% postfixed accent notation, instead of a prefixed one, none of these macros would
% be necessary (probably\dots!), but there would be other inconveniences.
%
% Notice that the following code is subject to the boolean variabale |GlyphNames|
% which is set to true by default, just fort compatibility with the past; I suggest
% to use the \emph{NoGlyphNames} when typesetting new documents, since the glyphs
% are more asily specified by means of the extended accent macros that are also less
% restricted in their names; for a letter marked with a smooth breath and an acute
% accent you can indifferently type before the letter one of the following |\>\'|,
% |\>'|, |\'\>|, |\'>| at your choice. Moreover you can always postfix the mark for
% the iota subscribed at the right of the letter, without any need o memorising
% complicated names.

% Macro |\q| is used to insert a Latin ``q'' while typesetting in Greek.
%\begin{macro}{\yod}
%\begin{macro}{\iod}

%\begin {macro}{\Digamma}
% At the same time it was believed that for inserting lower and upper case
% ``digamma'' it was preferable to use short macros and to avoid the dilemma between
% the |\ddigamma| and the |\digamma| macros, the former being the
% one defined in the \texttt{greek} extension to \babel, the latter being
% a standard mathematical symbol; initially I believed that philologists do
% not use mathematical symbols so we made |\digamma| an alias for |\f|; afterwards I
% found out that mathematicians, physicists, engineers,~\dots\ use the
% \textsf{teubner.sty} package and that the |\digamma| is a symbol already defined
% in the package \textsf{amssymb.sty}; therefore I made a conditional creation of
% this alias; this trick is delayed to the beginning of the document, so as to make
% it independent on the order with which packages are loaded.

%\begin {macro}{\fLow}
%\begin {macro}{\fHigh}
% The digamma glyphs set forth another question because, according to Paolo Ciacchi,
% a different glyph should be used for typesetting text compared with the one that
% is used as a variant in Milesian numerals in place of the standard stigma symbol.
% By means of macros |\fLow| or |\fHigh| it is possible to chose the raised or the
% lowered digamma glyphs; Greek numerals always use the lowered one, while when text
% is being typeset the typesetter can chose the version he likes best.

% therefore we need to quietly change fonts behind the scenes. The same is true with
% the question mark that, philologically speaking, represents an uncertain element,
% not the termination of a real question; it should therefore always come out
% between parentheses and in upright shape from a Latin font. While the
% parenthesized question mark comes from the OT1 Latin upright font, the parentheses
% obtained with |\lpar| and |\rpar| are taken from the metric symbols font, as well
% as the parentheses used in the parenthesized text processed with macro |\frapar|.

% \subsection{Poetry environments and macros}
%\begin {macro}{\verso}
%\begin{environment}{versi}
% Here we start with verse environments; we already explained that we defined three
% new verse environments that typeset poetry in ``in-line'' verses,
% ``numbered by five'' verses, and ``numbered by five and subnumbered'' verses.
% For the environment |versi| we first need a counter and a little macro for
% generating the short bar that has to receive the verse number as a ``limits''
% superscript.
%    \begin{macrocode}
\newcounter{verso}\setcounter{verso}{0}
\newcommand{\smallvert}{\vrule\@height.6ex\@depth.4ex}

%    \end{macrocode}
% Next we define the macro |\verso| that sets the small bar with the verse number on
% top. Since the initial numbering might be different from~1, |\verso| accepts an
% optional argument, which is intended to be the initial counter value. Since
% |\verso| steps up the counter a different action must be taken if the optional
% argument is present; in order to be able to reference such verse by means of the
% |\label|--|\ref| cross reference mechanism, this stepping up must be done by means
% of |\refstepcounter|; therefore we have to leave |\refstepcounter| outside the
% conditional code, and step down the counter by one unit only in case the initial
% value is specified.
%    \begin{macrocode}
\DeclareRobustCommand\verso[1][]{%
    \def\@tempA{#1}\ifx\@tempA\empty
    \else
        \setcounter{verso}{#1}\addtocounter{verso}{\m@ne}%
    \fi
    \refstepcounter{verso}%
    \@killglue\space
    \ensuremath{\mathop{\smallvert}\limits^{\scriptscriptstyle\theverso}}%
    \space\ignorespaces}

%    \end{macrocode}
% Now that the verse separation macro is ready we can define the environment; the
% required opening statement argument represents a short text whose width is taken
% as a measure for indentation, so that verses are typeset with a left margin that
% leaves out this short text. Substantially this environment is a \texttt{list} one,
% and the left margin variable width is totally similar to the one used in
% |thebibiography| environment. Also the |\makelabel| command has been modified
% accordingly.
%    \begin{macrocode}
\newenvironment{versi}[1]{%
\def\makelabel##1{##1}
\setbox\z@\hbox{#1}%
\list{}{\labelwidth\wd\z@\leftmargin\labelwidth
    \advance\leftmargin\labelsep}%
    \item[\box\z@]
}{%
\endlist
}
\let\versus\versi \let\endversus\endversi
%    \end{macrocode}
%\end{environment}
%\end{macro}
%
%\begin{environment}{Versi}
% The second environment |Versi| accepts an optional starting number in the opening,
% statement, whose default value is~1: verses are composed as in the standard
% \LaTeX\ |verse| environment (with one minor difference) except they are numbered
% in the left margin with a progression of five; only verse numbers that are integer
% multiples of five are displayed. The minor difference is that stanzas cannot be
% marked with a blank line in the input |.tex| file, as it is customary with
% the standard environment, but if a visual mark is desired, such as extra vertical
% space, it is necessary to resort to the optional spacing parameter that can be
% specified to the |\\| command. This environment uses the same verse counting
% counter, defined for use with the |versi| environment.
%
%\begin{macro}{\BreakVersotrue}
%\begin{macro}{\BreakVersofalse}
% For specific purposes it is necessary to have a boolean variable for allowing or
% prohibiting verses to split up at the end of line; the default is not
% to split.
%    \begin{macrocode}
\newif\ifBreakVersi
\BreakVersifalse
\newenvironment{Versi}[1][1]{%
    \setcounter{verso}{#1}%
%    \end{macrocode}
%\end{macro}
%\end{macro}
% An internal macro |\writ@verso| does not actually write out the complete, possibly
% numbered verse, but provides for checking that the verse counter contains a
% multiple of~5, and to write it out using old stile numbers; in case the number is
% not an integer multiple of~5 the number is written out as the |\empty| macro.
%    \begin{macrocode}
    \def\writ@verso{%
        \count255=\value{verso}\divide\count255by5\relax
        \multiply\count255by5\relax
        \advance\count255-\value{verso}%
        \ifnum\count255=\z@
          {\fontseries{m}\small\expandafter\oldstylenums\expandafter{\the\c@verso}}%
        \else
          \empty
        \fi}%
%    \end{macrocode}
% Since the |\\| command should provide the same functionality as the regular
% \LaTeX\ command, while in this environment it should provide other
% functionalities, such as triggering the display of the verse number. It is
% necessary to define an intermediate command |\v@rscr|, that examines the possible
% optional arguments, such as the optional star or the brackets enclosing vertical
% spacing
%    \begin{macrocode}
    \def\\{\@ifstar{\v@rscr{\@M}}{\v@rscr{\z@}}}%
    \def\v@rscr##1{\@ifnextchar[{\wr@teverse{##1}}%
        {\wr@teverse{##1}[\z@]}}%
%    \end{macrocode}
% Finally the |\wr@teverse| macro does the actual typesetting of the verse. Notice
% that the environment opening statement and every succeeding previous verse starts
% an horizontal box where the contents of the current verse is stored. Therefore the
% first thing to do is to close the box with the |\egroup| command, then a line of
% text is output that contains a possibly empty box or the verse number and the
% command for stepping up the verse counter, followed by the verse box number~0 and
% an end of paragraph; in this way the |\\| operates always in vertical mode,
% contrary to what happens in the |verse| standard \LaTeX\ environment. Even in this
% environment the actual typesetting is done within a |list| environment, whose

% I have experienced some problems in typesetting verses in two-column format; the
% column width might be too short for setting up verses even if verses are not that
% long, because in the left margin there must be room for the verse numbering; for
% homogeneity the spacing must conform also with the following environment
% \texttt{VERSI} that has a secondary verse numbering, therefore it can't be too
% small. The result is that there might be a test for controlling the two-column
% format, but I think that it is more useful for the typesetter to be able to switch
% on and off the possibility of breaking long verses on more lines.
% On two-column format in any case it is better to leave the right margin to
% coincide with the column right margin.

% the secondary enumeration.
% The new length represents an indentation of those verses that do no have the

% Ciacchi observed that a regular `H' with serifs was better looking than the sans
% serif counterpart. Therefore the definition was changed in order to use the
% current font upright shape; by specifying `H', it is irrelevant if the current one
% is a Latin font, and the letter is a capital 'h', or if the current one is a Greek
% font and the letter is a capital `eta'. |\Hiatus| displays the same symbol in a
% zero width box so that it does not occupy any horizontal space; it is useful while

% die out by themselves when a group is closed, but it is a good habit to explicitly
% turn them out regardless of groups. Attention that when the tracing facilities are
% on and a page ship out takes place, the |.log| file receives a lot of material,
% and this file gets very large. In order to avoid logging too much information the
% |trace| package is loaded; this package give access to the macros |\traceon| and
% |\traceoff| that log a lot of information, except the redundant one, specifically
% all the macros executed during any font change. Users don't realize the amount of
% processing done behind the scenes when with the New Font Selection Scheme (NFSS) a
% font change takes place; luckily enough modern processors are quite fast so that
% the compilation CPU time does not become too heavy. But if the \TeX\ processing is
% logged, this amount of work implies thousands of lines of almost meaningless
% information when the purpose of logging depends on errors that are difficult to
% spot; Font changes are almost exempt from errors, so the processing of the inner
% workings need not be logged down.

% \subsection{Classical Greek numerals}
% When typesetting Greek it may occur to specify numbers written out as Milesian
% numerals; the \texttt{greek} option to the \babel\ package defines a couple of
% macros for transforming explicit arabic numerals or counter contents as Milesian
% numerals. Since this package offers more possibilities in the choice of those
% ``non alphabetic'' characters used in the Milesian notation, such macros have to
% be redefined. On the occasion we changed some little internal details so as to make such macros a little faster and more robust.
%\begin{macro}{\Greeknumeral}
%\begin{macro}{\greeknumeral}
%\begin{macro}{\@ifStar}
%\begin{macro}{\grtoday}
% Both |\gereeknumeral| and |\Greeknumeral|, the latter producing upper case Greek
% numerals, while the former produces lower case ones, resort to a service macro
% |\gr@@numeral|. But the new definition accepts the starred version; without the
% star the digit value~6 is represented with a ``stigma'', while with the star that
% value is represented with a lowered ``digamma''. The upper case version requires
% intermediate macros before using |\MakeUppercase| on the result in order to
% convert lower to upper case Milesian value symbols. This means that |\gr@@numeral|
% may work only with lower case symbols.
% It turned out that the normal redefinition command |\renewcommand| produced
% fragile commands that broke out when used as arguments of other commands,
% specifically the Greek date was broken when it was passed as the argument to the
% |\date| command of the class \textsf{memoir}; therefore I decided to redefine the
% |\@ifstar| macro into another |\@ifStar| one so as not to fiddle with \LaTeX\ 
% kernel commands. I defined also the lowercase version of the |\grtoday| date,
% since the \babel\ package provides only the |\today| command with no control over
% the use of which type of numerals; |\grtoday| uses the lowercase Milesian numerals
% through the redefined |\greeknumeral| macro.

% allowable range contains at maximum six decimal places. Apparently Milesian
% symbology allows to go beyond one million, but Apostolos Syropoulos, who
% originally wrote the code thought (correctly) that Milesian numbers would not be
% used for ``acrobatic performances'' but possibly for writing the Greek date with
% the AD year; six decimal places are more than enough for this purpose.
% |\gr@ill@value| was not redefined from Apostolos Syropoulos' \babel\ definition;
% it simply issues a warning message about an argument out of range. The presence of
% the primitive command |number| in these macros is for two purposes: (a) transforms
% a counter contents into a sequence of digits tokens, and (b) if the argument is
% already a digit string, it removes any leading zeros. No braces are present
% because this string is examined sequentially one digit at a time from the leading
% position to the least significant position; of course this means that the decimal
% zero is treated correctly even if Milesian symbols do not have the equivalent of a
% zero.

%\subsection{Attic numerals}
% It's true that Apostolos Siropoulos wrote also the |athnum.sty| extension package
% in order to typeset integer numbers with the Athenian or Attic notation; this
% representation of integer strictly positive integers was similar in a way to the
% Roman notation, based on a biquinalry representation of decimal digits (taking
% into account that there was not a symbol for zero) so as the Romans had the
% symbols for 1, 5, 10, 50, 100, 500 and 1000 (I, V, X, L, C, D, M) the Attic
% notation has symbols for the same sequence of decimal values extended with 
% 10\,000 and 50\,000. While typesetting philological texts in Greek it might be
% necessary to use also the Attic notation. % As the original Roman notation used
% to be purely additive (i.e.\ 9\,=\,VIIII), so is the Attic notation.
%
%\begin{macro}{\AtticNumeral}
%\begin{macro}{\AtticCycl@}
% Therefore another conversion macro was devised that receives the value to be
% converted as its argument and checks that it falls between the boundaries;
% actually the lower boundary is zero, while the upper boundary was chosen to be
% 99\,999, for no other reason that the lack of further symbols, beyond the value
% 50\,000, would force to long sequences of identical symbols that are difficult
% to read.  The |athnum.sty| package allows to extend this range to 249\,9999;
% should it be necessary, the user is invited to load that package and its
% transformation command |\athnum|.
%
% The user command |\AtticNumeral| is very simple, but it must be preceded by the
% definitions of the quinary symbols for 50, 500, 5000, and 50\,000; such symbols
% are present in all the CB Greek fonts in all sizes, series and shapes; therefore
% the definitions must be subject to the LGR enconding:
%    \begin{macrocode}
\DeclareTextSymbol{\Vmiria}{\GRencoding@name}{5}
\DeclareTextSymbol{\Vkilo}{\GRencoding@name}{4}
\DeclareTextSymbol{\Vetto}{\GRencoding@name}{3}
\DeclareTextSymbol{\Vdeka}{\GRencoding@name}{2}
%    \end{macrocode}
% The we need a command for issuing a warning message if the number to be
% transformed is out of range:
%    \begin{macrocode}
\newcommand*\attic@ill@value[1]{\PackageWarning{teubner}{%
Illegal value (\number#1) for \string\ActicNumeral\space}}
%    \end{macrocode}
% Finally the robust definition of the |\AtticNumeral| command"
%    \begin{macrocode}
\DeclareRobustCommand*\AtticNumeral[1]{%
\ifnum#1<\@ne \attic@ill@value{#1}\else
  \ifnum#1>99999\relax \attic@ill@value{#1}\else
    \AtticCycl@{#1}
  \fi
\fi}

%    \end{macrocode}
% The real transformation algorithm is transfered to the auxiliary macro
% |\AttiCycl@|, where successive division by 10 allow to extract the various decimal
% digits of various weights maintaining the remainder in the original counter; each
% decimal digit is possibly divided into the quinary value and the remaining units
% up to 4; the the cycle is repeated untile the decimal units, that do not require
% the computation of the remainder and terminate the cycle. Notice that we use also
% the $\varepsilon$-\TeX\ extended commands for integer computations; this implies
% that |teubner| mus be run with a suitably recent version of the typesetting engine
% that embeds the above extensions.

   [2010/05/08 v.2.0a Definitions of accents and glyphs for LGR encoded Greek fonts]
%    \end{macrocode}
% \subsection{First set of extended accent definitions}
% These macros were originally defined by Guenter Milde
% in his file lgrenc-accents.def version 3.2 dated 2008-06-17
% and released under the LPPL LaTeX Project Public License
% version 1.3 or ay later version.
% 
% These macros were slightly modified by Claudio Beccari
% in this file, version 1.0 of 2010-04-13, in order to adapt them
% to the teubner.sty package, but they can be used independently of 
% this package.
%
% This modified version is released again under the LPPL license
% version 1.3c or any later version.
%
% These definitions are a modest variation of the standard LGR
% encoded ligature set, in the sense that they don't rely on
% ligatures but on accent  and composite text macros that address
% directly the accented glyphs.
%
% For example, if alpha with smooth spirit, acute accent and iota
% subscribed has to be inserted in the Greek text, the user
% can use either one of the following solutions:
% \begin{quote}
%    1) \verb+>'a|+ \\
%    2) \verb+\>'a|+
% \end{quote}
% Solution 1) saves hitting one key but breaks the kerning mechanism;
% Solution 2) requires hitting one more key but preserves the kerning
% mechanism.
%
% Only the diacritics that involve the breve (\u) and the macron (\=)
% are regular TeX accent macros and behave as ordinary OT1-like
% accents. There is no addressing of the marked glyphs, because the 256
% font table can't accommodate so many glyphs.
%
% This file should be usable by inputting it even without requiring the
% polutoniko language attribute of the Greek language.
%
% For more details read the teubner.pdf and the teubner-doc.pdf files
% that are part of the teubner package documentation.

% \subsection{Second set of extended accent definitions}
% Now come another bunch of Milde's macros for composite glyphs; none of them
% involves glyphs containing the subscript or adscript iota; this symbol, in facts
% is postfixed to the previous glyph macro description, so its ligature takes place
% after the previous glyph macro has been expanded; remember also that with the
% ``high accents'' you can use both input strings, for example: |>'| and |\>'|;
% therefore you can use the simple ligature input and, if kerning is not working
% well with certain glyphs, you can just add a backslash in front of the ligature
% sequence and everything gets fixed with proper ligatures. So, if |a>'u| with
% certain fonts results in broken kerning, you just change it to |a\>'u| and the
% kerning gets fixed.

% With capital letters the dialytika (diaeresis) is maintained on top of the letters
% `I' and `U', while for the other capital letters the diacritics are typeset in
% front of them, not on top of them, as it is customary with Greek typesetting best
% practice; the Unicode capital accented glyphs do exist, but they should never be
% used; the CB fonts don't even contain them. There is no concern with kerning
% because the diacritics preceding the capital letters are not preceded by something
% else; what follows is kerned the usual way. With \"I and \"U specific kernings are
% provided, if the dialytika macro |\"| is used, while kerning dith the dialytika

% the CB fonts have because the |AU| and |A'U| kerning was terrible without them;
