+% \begin{abstract}
+% 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 the \TeX-Live CD; 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 mark 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, while the metric symbols font is
+% included in this bundle; it does not need a formal font definition file, because
+% the necessary definitions are included in this package.
+%
+% 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.
+%
+% \DescribeEnv{versi}\DescribeMacro{\verso}  The environment \texttt{versi}
+% is used to typeset verses
+% in line, without an 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} is similar to the
+% standard \LaTeX\ environment \texttt{verse}, except verses 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} 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{Code}
+% The beginning of the file starts with the traditional stuff;
+% as usual we provide also the means for avoiding reading this file again.
+%    \begin{macrocode}
+%<*package>
+\ifx\teubner\undefined
+    \def\teubner{teubner}\else\expandafter\endinput
+\fi
+%    \end{macrocode}
+% 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 is necessary because apparently the
+% pfb math extensible 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 appears a little too fat and does not join exactly le left mark. Therefore we
+% define a new boolean\footnote{Thanks to Yuqing Deng who spotted an error somewhere else,
+% that followed from an improper definition of the state variable \texttt{\string\ifPDF} such
+% that the program performed correctly under \texttt{pdflatex} and crashed under \texttt{latex}.}:
+%    \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.
+%    \begin{macrocode}
+\ifx\captionsgreek\undefined
+\PackageError{teubner}{Greek language unknown!\MessageBreak
+I am not going to use Lipsian fonts and Scholars' signs\MessageBreak
+if Greek is unknown.\MessageBreak
+Use the babel package with the \texttt{greek} option.\MessageBreak
+Type X <return> to exit.}%
+{Type X <return> to exit.}
+\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{vowel}\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.
+% At the same time since all accent combinations are defined as ``text commands'', in \LaTeX\ jargon,
+% when their commands are followed by a vowel they define a ``text symbol'' that is directly the
+% glyph of the accented vowel; 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.
+%    \begin{macrocode}
+\newif\ifor\orfalse % Compatibility with older versions
+\DeclareOption{or}{\relax}
+\ProcessOptions*
+%    \end{macrocode}
+%
+% 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{macrocode}
+\def\GRencoding@name{LGR}
+%    \end{macrocode}
+%
+% Now the default Olga Greek fonts, used for rendering the ``Greek italic shape''
+% are substituted with the Lipsian ones; this simply requires to reenter the
+% shape definition commands used in the font description file with new commands
+% that refer to the Lipsian fonts; the font encoding is already known to the package
+% so that any encoding dependent name is correctly defined:
+% \begin{macrocode}
+\input{lgrcmr.fd}
+\expandafter\EC@family\expandafter{\GRencoding@name}{cmr}{m}{it}  {grml}
+\expandafter\EC@family\expandafter{\GRencoding@name}{cmr}{bx}{it} {grxl}
+%    \end{macrocode}
+%
+% \begin{macro}{\metricsfont} Similarly the metric symbol font is declared together
+% with a command for selecting it:
+% \begin{macrocode}
+\DeclareFontFamily{U}{mtr}{\hyphenchar\font\m@ne}
+\EC@family{U}{mtr}{m}{n}{gmtr}
+\DeclareFontShape{U}{mtr}{m}{it}{<->ssub*mtr/m/n}{}
+\newcommand*\metricsfont{\fontencoding{U}\fontfamily{mtr}\upshape}
+%    \end{macrocode}
+% \end{macro}
+% Next we require the package for extensible math fonts; it might be strange to use
+% extensible math fonts in Greek philology, but a certain command must be picked up
+% from such fonts, with the assurance that it changes size together with the current
+% font size.
+% \begin{macrocode}
+\RequirePackage{exscale}
+%    \end{macrocode}
+%
+% Some macros are necessary to switch languages; such macros must be independent
+% (at least for now) from the particular \babel\ version, whether it be version 3.6
+% or~3.7; in the former the concept of language attribute is unknown, while the latter
+% recognizes varieties of the same language by the attribute setting. Such macros,
+% besides being as robust as possible, must provide the alphabet changes as required.
+%\begin{macro}{\GreekName} During the language switching operations  |\GreekName|
+% distinguishes the dialect or the main language whose attribute
+% gets set and, evidently, becomes effective when the main language \texttt{greek}
+% is in force.
+%    \begin{macrocode}
+\ifx\languageattribute\undefined
+ \def\GreekName{polutonikogreek}%
+\else
+ \languageattribute{greek}{polutoniko}\def\GreekName{greek}%
+\fi
+%    \end{macrocode}
+%\end{macro}
+%\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:
+%    \begin{macrocode}
+\AtBeginDocument{%
+    \edef\previouslanguage{\languagename}%
+    \edef\previousencoding{\f@encoding}%
+}
+%    \end{macrocode}
+% Nevertheless 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 o resets font definitions,
+% in particular if font encoding is defined; 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\dots, well, unless you are going to write
+% all your document in Greek; in this case the only switching you need is between
+% Didot characters and Lipsian characters (which is simply done by means of |\upshape|
+% and |\itshape|); in any case specify the polytonic spelling.
+%\end{macro}
+%\end{macro}
+%
+%\begin{macro}{\Lipsiakostext} |\Lipsiakostext| is a declaration stating that from now on
+% typesetting will be done with the Lipsian fonts; notice that the encoding and the
+% language name in force before this declaration are memorized, then the current
+% Greek version is selected; the |\let\~\GRcirc| is required because swithching
+% on and off may reset the active tilde and connected macros definitions. |\~| in Greek
+% must set the circumflex accent, so we make sure that this really occurs.
+%    \begin{macrocode}
+\DeclareRobustCommand\Lipsiakostext{\edef\previouslanguage{\languagename}%
+    \edef\previousencoding{\f@encoding}%
+    \expandafter\select@language\expandafter{\GreekName}%
+    \let\~\GRcirc\let~\greek@tilde\itshape}
+%    \end{macrocode}
+%\end{macro}
+%\begin{macro}{\NoLipsiakostext} |\NoLipsiakostext| is the opposite declaration
+% that undoes everything that was done with |\Lipsiakostext|.
+%    \begin{macrocode}
+\DeclareRobustCommand\NoLipsiakostext{%
+    \expandafter\select@language\expandafter{\previouslanguage}%
+    \expandafter\fontencoding\expandafter{\previousencoding}\upshape
+    \edef\previouslanguage{\languagename}%
+    \edef\previousencoding{\f@encoding}\bbl@activate{~}%
+}
+%    \end{macrocode}
+%\end{macro}
+%\begin{macro}{\textLipsias} |\textLipsias| is a command that typesets its argument
+% with the |\Lipsiakostext| declaration in force; actually the external font encoding
+% and language are not memorized, because the pertinent Greek commands are just local.
+%    \begin{macrocode}
+\DeclareRobustCommand\textLipsias[1]{{%
+    \expandafter\select@language\expandafter{\GreekName}%
+    \expandafter\fontencoding\expandafter{\GRencoding@name}%
+    \itshape\let\~\GRcirc\let~\greek@tilde#1}%
+}
+%    \end{macrocode}
+%\end{macro}
+%\begin{macro}{\textDidot} |\textDidot| is a similar macro where the common upright
+% Greek characters are selected; it goes by itself that if |\textit| is specified
+% within the |\textDidot| argument, the typesetting is or becomes identical with what
+% one can obtain with the |\textLipsias| command.
+%    \begin{macrocode}
+\DeclareRobustCommand\textDidot[1]{{%
+    \expandafter\select@language\expandafter{\GreekName}%
+    \expandafter\fontencoding\expandafter{\GRencoding@name}%
+    \upshape\let\~\GRcirc\let~\greek@tilde#1}%
+}
+%    \end{macrocode}
+%\end{macro}
+%\begin{macro}{\textlatin} |\textlatin| is a redefinition of the standard \babel\
+% macro that is adapted to the present situation, where it may be called behind the
+% scenes in certain situations that are beyond the control of the typesetter. Therefore
+% every precaution is taken in order to be sure that the composition of the command
+% argument is really done with the default encoding.
+%    \begin{macrocode}
+\DeclareRobustCommand\textlatin[1]{\edef\externalencoding{\f@encoding}{%
+    \expandafter\select@language\expandafter{\previouslanguage}%

+% Now we start the specific additions introduced with this package.
+%
+% \begin{macro}{\numero}
+% We define a short macro |\numero| used to strip off the pt part of a dimension value
+% as displayed by \TeX\ itself; this service macro is going to be used quite a lot for
+% getting the font slant per point parameter so as to be able to put in their correct
+% position various signs over or under other signs.
+% \begin{macrocode}
+{%
+\catcode`p=12\catcode`t=12\gdef\numero#1pt{#1}%
+}
+%    \end{macrocode}
+% \end{macro}
+%
+% 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.
+% \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}
+\newcommand*\lift@accent[2]{\leavevmode
+{\edef\slant@{\expandafter\numero\the\fontdimen1\font}%
+\dimen@=\z@\setbox\z@\hbox{\char#1}\advance\dimen@-.5\wd\z@
+\setbox\tw@\hbox{i}\setbox\z@\hbox{#2}%
+\ifdim\wd\z@>\wd\tw@\advance\dimen@ .5\wd\z@
+    \else\advance\dimen@ .3\wd\z@\fi
+\ifx#2a\advance\dimen@-.1\wd\z@\fi

+\advance\dimen@\slant@\@tempdima
+\raise\@tempdima\hbox to\z@{\kern\dimen@\char#1\relax\hss}\box\z@}}
+%    \end{macrocode}
+% \end{macro}
+%
+%
+% \begin{macro}{\Lift@accent} The second ``lift accent'' macro behaves
+% as the first one except it interposes a small
+% vertical distance between the accent and the letter:
+% \begin{macrocode}
+\newcommand*\Lift@accent[2]{\leavevmode
+{\edef\slant@{\expandafter\numero\the\fontdimen1\font}%
+\dimen@=\z@\setbox\z@\hbox{\char#1}\advance\dimen@-.5\wd\z@

+\advance\dimen@\slant@\@tempdima
+\raise\@tempdima\hbox to\z@{\kern\dimen@\char#1\relax\hss}\box\z@}}
+%    \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
+{\edef\slant@{\expandafter\numero\the\fontdimen1\font}%
+\dimen@=\z@\setbox\z@\hbox{\char#1}\advance\dimen@-.5\wd\z@
+\setbox\tw@\hbox{i}\setbox\z@\hbox{#3}%
+\ifdim\wd\z@>\wd\tw@\advance\dimen@ .5\wd\z@

+\@tempdima\ht\z@\advance\@tempdima-1ex\relax
+\def\@tempA{#2}\ifx\@tempA\undefined\else
+\advance\@tempdima#2\fi\let\@tempA\undefined
+\advance\dimen@\slant@\@tempdima
+\raise\@tempdima\hbox to\z@{\kern\dimen@\char#1\relax\hss}\box\z@}}
+%    \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@{\expandafter\numero\the\fontdimen1\font}%
+\setbox\tw@\hbox{\fontencoding{\GRencoding@name}\selectfont
+    \char1}\dimen@-.5\wd\tw@
+\setbox\z@\hbox{#1}%
+\advance\dimen@ .5\wd\z@
+\@tempdima\ht\z@\advance\@tempdima.55ex\relax
+\advance\dimen@\slant@\@tempdima
+\ifx\cf@encoding\GRencoding@name\else
+\ifx#1k\advance\dimen@-.3\wd\tw@\fi\fi
+\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 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 other encodings.
+% \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
+{\setbox4\hbox{\fontencoding{\GRencoding@name}\selectfont\char1}%
+\dimen@-.5\wd4
+\setbox\z@\hbox{#1}%
+\ifx\cf@encoding\GRencoding@name
+\ifx#1i\advance\dimen@ .65\wd\z@\else\advance\dimen@ .6\wd\z@\fi
+\else
+\ifx#1i\advance\dimen@ .55\wd\z@\else\advance\dimen@ .5\wd\z@\fi
+\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 correct positioning requires
+% careful examination of the letter under which it is to be placed, distinguishing
+% the Greek from the Latin encodings:
+% \begin{macrocode}
+\newcommand*\ring@cedilla[1]{\leavevmode
+{\setbox4\hbox{\metricsfont\char26}%
+\edef\slant@{\expandafter\numero\the\fontdimen1\font}%
+\dimen@-.5\wd4\ifdim\slant@\p@>\z@\advance\dimen@-.04ex\fi
+\setbox\z@\hbox{#1}%
+\ifx\cf@encoding\GRencoding@name
+    \advance\dimen@ .45\wd\z@
+    \ifx#1h\advance\dimen@-.13\wd\z@\fi
+    \ifx#1a\advance\dimen@-.07\wd\z@\fi
+    \ifx#1o\advance\dimen@-.07\wd\z@\fi
+    \ifx#1u\advance\dimen@+.07\wd\z@\fi
+    \ifx#1w\advance\dimen@+.03\wd\z@\fi
+\else
+    \ifx#1i\advance\dimen@ .55\wd\z@\else
+    \ifx#1r\advance\dimen@.38\wd\z@\else
+    \ifx#1o\advance\dimen@.47\wd\z@\else
+           \advance\dimen@ .5\wd\z@
+    \fi\fi\fi
+\fi
+\hbox to\z@{\kern\dimen@\box4\hss}\unhbox\z@}}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\dot@cedilla} Even the standard \LaTeX\ macro |dot| must be redefined
+% with a cedilla like macro, so as to make use of a special dot from the
+% metric symbols font:
+% \begin{macrocode}
+\newcommand*\dot@cedilla[1]{\leavevmode
+{\setbox4\hbox{\metricsfont\char27}%
+\dimen@-.5\wd4
+\setbox\tw@\hbox{i}\setbox\z@\hbox{#1}%
+\ifx\cf@encoding\GRencoding@name
+    \advance\dimen@ .5\wd\z@
+    \ifx#1h\advance\dimen@-.13\wd\z@\fi
+\else
+    \ifdim\wd\z@>\wd\tw@\advance\dimen@.55\wd\z@
+        \else\advance\dimen@.5\wd\tw@\fi
+\fi
+\setbox\tw@\hbox{o}\ifdim\wd\z@=\wd\tw@\advance\dimen@-.05\wd\z@\fi
+\hbox to\z@{\kern\dimen@\box4\hss}\unhbox\z@}}
+%    \end{macrocode}
+%\end{macro}
+%
+% \begin{macro}{\tie@cedilla} \LaTeX\ has the macro |\t| for placing a ``tie'' over two
+% letters; philologists require also a tie under two letters; this is why another
+% cedilla like macro is needed:
+% \begin{macrocode}
+\newcommand*\tie@cedilla[1]{\leavevmode % mette un tie sotto l'argomento
+{\setbox4\hbox{\fontencoding{\GRencoding@name}\selectfont\char20}%
+\dimen@-.5\wd4
+\setbox\tw@\hbox{i}\setbox\z@\hbox{#1}%
+\ifx\cf@encoding\GRencoding@name
+    \advance\dimen@.5\wd\z@
+    \ifx#1h\advance\dimen@-.1\wd\z@\fi
+    \ifx#1u\advance\dimen@.15\wd\z@\fi
+\else
+    \ifdim\wd\z@>\wd\tw@\advance\dimen@ .55\wd\z@
+        \else\advance\dimen@ .5\wd\tw@\fi
+\fi
+\setbox\tw@\hbox{o}\ifdim\wd\z@=\wd\tw@\advance\dimen@-.05\wd\z@\fi
+\hbox to\z@{\kern\dimen@\box4\hss}\unhbox\z@}}
+%    \end{macrocode}
+% \end{macro}
+% All these accent like and cedilla like macros will be extensively used in the following
+% definitions.
+%    \begin{macrocode}
+% grave
+\DeclareTextCommand{\`}{\GRencoding@name}[1]{\lift@accent{96}{#1}}
+% acute
+\DeclareTextCommand{\'}{\GRencoding@name}[1]{\lift@accent{39}{#1}}
+% circumflex
+\DeclareTextCommand{\GRcirc}{\GRencoding@name}[1]{\lift@accent{126}{#1}}
+\DeclareTextCommand{\~}{\GRencoding@name}[1]{\lift@accent{126}{#1}}
+%    \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 ``big 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}}

+\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|; 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. 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
+% in Greek as |\semiv|.

+% Several macros are traditionally defined for every encoding; we do not make exceptions.
+% Actually all the symbols defined here can be obtained with the regular CB font ligatures
+% so the macros are sort of superfluous. Nevertheless, in case any of the component symbols
+% is made active and defined to perform something different, these macros can overcome
+% the difficulty of producing the ligated glyphs. Even the |\textcompwordmark| macro,
+% although the compound word mark is sort of unusual, could have been omitted, because
+% with a Latin keyboard this symbol gets input by pressing the ``v'' key (``v'' stands
+% for ``void''); all the hyphenation pattern files for the Greek language recognize
+% ``v'' as a letter, an invisible letter, that breaks any ligature, that hides the end
+% of the word, that allows hyphenation (if the rest of the word is taken as a
+% \emph{word} by \TeX\ itself, which does not happen all the time!).

+% Now come the 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.

+% At the same time it was believed that for inserting lower

+% 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.

+% 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.

+% Here we start a set of miscellaneous macros. We begin with some parentheses
+% that should turn out in upright shape, even if the default font is the Lipsian
+% one which is oblique; its parentheses are oblique as in all oblique fonts, 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|.

+% Philologists require a certain number of special parentheses in order to

+% been modified under the assumption that the copyist made some error.
+% Such enclosing marks include angle brackets, square brackets, upper part
+% of square brackets, lower part of square brackets. Such symbols may even
+% appear doubled. Most if these glyphs have been designed anew, because they
+% are missing or are inadequate if they are taken from the usual CM fonts (either
+% text or math fonts). Brackets for example have been designed as to be higher
+% and deeper than the font total height, so as not to interfere with Greek
+% accents and to accomodate for at least one level of nesting (for example square brackets
+% enclosing lower part of square brackets. The single glyphs may be used directly by
+% the typesetter, but we think that the commands requiring some text are fare more useful.
+% |\Ladd| and its double version |\LLadd| enclose text that should be added for sure.
+% |\ladd| and its double version |\lladd| enclose text that probably should be added.
+% |\lesp| and its synonymous |\ldel| enclose text that should be deleted.

+%
+% Now we come to another set of commands like the ones needed to mark the syneresis
+% or the zeugma and other similar marks.
+%\begin{macro}{\Utie} This first macro sets a ``smile'' symbol under a couple of
+% letters. The glyph is fine but is good only for two adjacent letters, therefore
+% it is necessary to have a stretchable symbol.
+%    \begin{macrocode}
+\DeclareRobustCommand\Utie[1]{%
+\mbox{\vtop{\ialign{##\crcr
+   \hfil#1\hfil\crcr

+   \hfil$\smile$\hfil\crcr}}}}
+%    \end{macrocode}
+%\end{macro}
+%
+%\begin{macro}{\siner}
+%\begin{macro}{\siniz} This is why the |\siner| and |\siniz| synonymous commands
+% have been defined; in place of the ``smile'' symbol they contain a stretchable
+% filler |\upfill| that behaves almost as the stretchable horizontal brace that is
+% used in the definition of the \LaTeX\ commands |\underbrace| or |\overbrace|.
+%    \begin{macrocode}
+\DeclareRobustCommand{\siner}[1]{%
+\mbox{\vtop{\ialign{##\crcr
+   \hfil#1\hfil\crcr
+   \noalign{\kern.6ex\nointerlineskip}%
+   \upfill\crcr}}}}
+\let\siniz\siner
+%    \end{macrocode}
+%\end{macro}
+%\end{macro}
+%\begin{macro}{\upfill} The |\upfill| is defined as a leader, the same way as the
+% corresponding \LaTeX\ stretchable horizontal brace; but as mentioned before we
+% introduce a correction in case we are typesetting with pdf\LaTeX, because the
+% pfb extensible math fonts, from wich the curved extremities are taken from, apparently
+% do not have the actual dimension declared in the tmf files.
+%    \begin{macrocode}
+\def\upfill{$\m@th \scriptstyle\setbox\z@\hbox{$\scriptstyle\bracelu$}%
+  \kern.16ex\bracelu\ifPDF\kern-.15ex\fi
+  \leaders\vrule \@height\ifPDF.85\fi\ht\z@ \@depth\z@\hfill
+  \braceru\kern.16ex$}
+%    \end{macrocode}
+%\end{macro}
+%\begin{macro}{\downfill} The down fill arc is totally similar to the  up fill one, except
+% for its terminating elements that change the shape of the arc from ``up'' to ``down''; we
+% introduce the same correction as in |\upfill| for the same reasons.
+%    \begin{macrocode}
+\def\downfill{$\m@th\scriptstyle\setbox\z@\hbox{$\scriptstyle\braceld$}%
+  \kern.16ex\braceld\ifPDF\kern-.15ex\fi
+  \leaders\vrule \@height\ifPDF.85\fi\ht\z@ \@depth\z@\hfill
+  \bracerd\kern.16ex$}
+%    \end{macrocode}
+%\end{macro}
+% With both macros we could have edited the pfb files, but this would have required
+% to distribute the corrected |cmex10.pfb| file together with the bundle, causing possible users
+% to mess up their map of PostScript fonts. Of course the chosen solution has the
+% opposite draw back: when and if the corrected pfb files will be distributed with each
+% more or less complete \TeX\ bundle, then this file will require to be corrected again. But
+% this is simple because it suffices to eliminate the whole |\ifPFB| business.
+%
+%\begin{macro}{\zeugma} Similarly |\zeugma| puts a stretchable arc over its
+% argument; it must take into account the slant of the argument font so
+% as to skew the placement of the arc.
+%    \begin{macrocode}
+\newcommand*\zeugma[1]{{\vbox{\setbox\z@\hbox{#1}\dimen@=\ht\z@

+%    \end{macrocode}
+%\end{macro}
+%
+%\begin{macro}{\slzeugma}
+%\begin{macro}{\rszeugma} Although the shape of oblique zeugma arcs cannot be
+% changed depending on the width and height of the zeugma argument, in certain
+% circumstances the philologists want to use oblique zeugma marks. This is why
+% we defined a ``sloping zeugma arc'' |\slzeugma|, and a ``rising zeugma arc''
+% |\rszeugma| that can be used with poor results, if such arcs are superimposed
+% over the ``wrong'' letters. There is nothing automatic in the choice of the
+% oblique arc and is totally on the typesetter responsibility to use the
+% correct command.

+%\begin{macro}{\nexus}

+% we had to use the Latin and (arbitrarily) the Italian name to distinguish them.

+% a ``stronger'' mark called ``Coronis'', which differs from the common ``coronis''
+% because it bears an  inverted semilunar sign on its left. Both marks are input
+% by means of their respective commands |\paragr| (preferred to |\coronis|) or

+%\begin {macro}{\verso}
+%\begin{environment}{versi} Here we start with verse environments; we already explained
+% we defined three new verse environments that typeset verses 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}
+%%%%%%%%%%%%%%%%%%%%%%%%%% verse environments
+\newcounter{verso}\setcounter{verso}{0}
+\newcommand{\smallvert}{\vrule\@height1ex}
+%    \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}%
+    \ensuremath{\mathop{\smallvert}\limits^{\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}
+\list{}{\settowidth\labelwidth{#1}\leftmargin\labelwidth
+    \advance\leftmargin\labelsep}%
+}{%
+\endlist
+}
+%    \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}
+% 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.
+%\end{macro}
+%\end{macro}
+%    \begin{macrocode}
+    \def\writ@verso{%
+        \count255=\value{verso}\divide\count255by5\relax
+        \multiply\count255by5\relax
+        \advance\count255-\value{verso}%
+        \ifnum\count255=\z@
+            {\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 parameters are set differently from what they are
+% in the |verse| environment. Notice in any case that the command |\wr@teverse| reopens
+% the~0 box, so on the last verse, upon closing the environment, it is necessary to
+% remember to close such box, whose contents is irrelevant and can be thrown away.
+%
+% 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.

+%
+%\begin{environment}{VERSI} The third environment |VERSI| set verses in the traditional
+% way, but numbers them with two different enumerations; the principal one is by
+% multiples of five, while the secondary one counts by units, and may be turned on and off,
+% or reset at will. We therefore need another counter for the secondary enumeration
+% and commands for turning it on and off and for resetting the counter. We need also
+% a new length and a new boolean variable in order to manage the secondary enumeration.
+% The new length represents an indentation of those verses that do no have the secondary
+% enumeration, while secondary enumerated verses are not indented. For \texttt{VERSI}
+% there is the same possibility of turning on and off the possibility of breaking verses
+% at the end of line as it happens for the environment \texttt{Versi}.
+% \begin {macro}{\SubVerso}
+% \begin {macro}{\NoSubVerso} Macro |\NoSubVerso| turns off the secondary enumeration;
+% macro |\SubVerso| turns on the secondary enumeration, but it accepts an optional
+% argument for resetting the secondary counter; the default value is~0; if no optional
+% argument is specified, and therefore if the optional argument has its default value~0,
+% no resetting is performed and the enumeration keeps going from the last contents of
+% the secondary counter; if the first use of |\SubVerso| does not contain the optional
+% argument, the secondary enumeration keep going from the old contents of the secondary
+% counter which is unpredictable, depending upon the previous occurrences of the
+% environment |VERSI|. The typesetter, therefore, must remember to specify the optional
+% argument to |\SubVerso| the first time he uses it in this environment.

+% changes in order to use the current font upright shape; by specifying `H', it is

+% Therefore we need a service macro |\stripsl@sh|that strips the first token from the control sequence, so that
+% the na\"{\i}f user does not have to treat the new metrics control sequence differently
+% from the control sequences it uses for example with |\newcommand|. Next we define
+% three numeric control sequences that should be followed by the rest of the macro name.
+% The na\"{\i}f user then can type in something like \verb*+\2iamb + in order to activate

+% die out by themselves when a group is closed, but it is a good habit to explicitly

+% 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 of converting 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.

+%\begin{macro}{\gr@@numeral} |\gr@@numeral| must do most of the processing; it must check
+% that the argument is within the allowable range $1\sim999\,999$ and issue suitable
+% warnings if not. On the other end if the number is within the correct range it must check
+% in which decade it falls and must call other macros so as to produce the correct
+% decimal digit~$\leftrightarrow$ Milesian symbol. Six such macros are needed because the
+% 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
+% the 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.

+% symbols.
+% The argument to each macro is a single decimal digit; their positional value is determined
+% by the calling macro that invokes a different transformation routine for every position.
+% to the right of the least significant position there must be the symbol ``anwtonos'',
+% similar to an apostrophe, while to the left of each the most significant symbol whose
+% value is greater than 999 there must be a ``katwtonos'' symbol, similar to a lowered
+% and inverted apostrophe. Zeros are examined in all macros, except the one for ``units'',
+% because their value cannot be printed but there still is the possibility that there are
+% no more digits higher than zero, so that the anwtonos must be set.
+% Macros |\n@vanta| and |\n@vecento| are set by the calling macros so as to be the
+% correct lower or upper case `qoppa' or sampi' respectively.
