+% \section{Overview}
+% The present document describes a new interface for the Ibycus fonts
+% to use them in conjunction with the Babel system for multilanguage typesetting.
+% It constitutes an alternative to the well-known macro packages
+% |ibycus4.sty| and |psibycus.sty|, which are distributed together with the
+% fonts. The main advantage over these packages is that automatic
+% hyphenation is provided for the Greek language. Notice, however, that
+% a \TeX\ program with the so-called \eTeX\ extensions is required.
+%
+% The implementation is available for \LaTeXe\ only; there are no
+% corresponding macro files for plain~\TeX\ or \LaTeX~2.09.
+%
+%
+% \section{{\boldmath Why \eTeX?}}
+% With `ordinary' \TeX,
+% hyphenation of Greek words will not work properly, if the end of a mixed Greek
+% and Latin-alphabet paragraph does not coincide with the end of the
+% Greek. This is due to a misfeature in \TeX: Only one set of
+% so-called lccodes is used throughout the length of a paragraph -- only
+% those which are valid at its end. These codes must be adjusted for
+% the Ibycus notation in order to tell \TeX\ that accents and breathings
+% a part of the words, rather than punctuation. So if you have reverted back
+% to a Latin-written language at the end of the paragraph, the wrong
+% codes for Greek hyphenation are in effect, and the diacritics in Greek words
+% are wrongly considered as punctuation.
+% The problem does, however, \emph{not} occur with an \eTeX\ program; i.e., a
+% \TeX\ program with certain extended capabilites. In fact, you are
+% probably already using \eTeX, even if you did not realize it.
+% All up-to-date \LaTeX\ systems are now built upon an \eTeX\ typesetting
+% engine, rather than on the classical \TeX\ program.
+%
+% \section{Usage}
+% The Ibycus fonts are assigned a (pseudo-)language named |ibycus|,
+% which can be used (almost) like any other language supported by
+% Babel. To enable the use of this language in your document, specify
+% it as an option to the Babel package just as you would do for any
+% other language. For instance, to write a document in German with
+% some Greek passages:
+% \begin{verse}
+% |\usepackage[ibycus,ngerman]{babel}|
+% \end{verse}
+%
+% A few caveats: Do not declare |ibycus| as the default
+% language of the document; it is not suitable for this purpose!
+% In other words, |ibycus| must never be the last option for Babel.
+% And, of course, do not use it together with the packages |ibycus4|
+% or |psibycus|.
+%
+% The language |ibycus| should be selected only locally. Either use
+% the |ibycus| environment
+% to typeset larger passages of Greek text:
+% \begin{verse}
+% |\begin{ibycus} | \\
+% | (Hrodo'tou Qouri'ou i(stori'hs a)po'decis h('de, | \\
+% | ... | \\
+% | h(`n ai)ti'hn e)pole'mhsan a)llh'loisi. | \\
+% |\end{ibycus} |
+% \end{verse}
+% or use the command |\ibygr|, which is more appropriate for
+% short pieces of Greek within Latin-written text:
+% \begin{verse}
+% |blah blah \ibygr{a)rxai=a gra'mmata} blah...|
+% \end{verse}
+% In fact, the environment |ibycus| is nothing but an abbreviation for
+% Babel's |otherlanguage| environment with the option |ibycus|, and
+% |\ibygr{...}| is the same as |\foreignlanguage{ibycus}{...}|.
+%
+% Within the environment |ibycus| or the argument of |\ibygr|,
+% the Ibycus-specific input notation is to be used to enter Greek. This
+% notation is described in the documentation that comes with the Ibycus
+% fonts.
+%
+% The typeface Ibycus and the related input notation can also be
+% selected without changing the hyphenation tables; to do so, use the
+% declaration |\ibycustext| or the text-generating command
+% |\textibycus{...}|. These macros exist more or less only as a
+% side-effect of the implementation; they should normally not be
+% needed.
+%
+% To switch temporarily back to the Latin alphabet within a piece of
+% Greek text (without, however, changing the hyphenation table), use
+% the declaration |\latintext| or the text-generating macro
+% |\textlatin{...}|. When Babel is loaded with the option |ibycus|,
+% these commands not only switch back to the default latin text font
+% encoding as usual; they also select the default roman font family
+% (just like |\rmfamily| or |\textrm|).
+%
+% Notice a particular difference between |ibycus| and other languages
+% of the Babel system: Switching to the language |ibycus| selects
+% both a particular font encoding (|U|) and a particular font family (|fib|),
+% regardless of the font family that was active before.
+%
+% The Ibycus typeface provides a few traditional text-editor symbols
+% for critical editions:
+%
+% \begin{center}
+% \begin{tabular}{ll}
+% \verb+\braceleft + & left curly brace \\
+% \verb+\braceright + & right curly brace\\
+% \verb+\bracketleftbt + & left half square bracket\\
+% \verb+\bracketrightbt+ & right half square bracket\\
+% \verb+\sdagger + & single dagger\\
+% \verb+\dbldagger + & double dagger\\
+% \end{tabular}
+% \end{center}
+% Use of these symbols is not restricted to Greek
+% passages. \textbf{Caution:}
+% In the Ibycus4 package the single dagger carries the name |\dagger|.
+% However, this macro belongs to the \LaTeX\ kernel and should not be redefined,
+% so the name |\sdagger| is now used for the Ibycus-specific symbol.
+%
+% \section{Scaling the Ibycus fonts}
+% The Ibycus typeface was primarily designed to go with Computer Modern;
+% yet it can be used with other Latin typefaces, too. In this case it
+% may sometimes be useful to typeset the Ibycus fonts a little bit larger
+% or smaller, to make them blend better with the Latin typeface.
+% This can be accomplished through the macro |\setgreekfontsize|. For instance,
+% |\setgreekfontsize{1.05}| will enlarge the Ibycus fonts by 5\%, as compared
+% with their nominal size. The command can be issued in the preamble only.
+%
+%
+% \section{The hyphenation patterns}
+% The hyphenation patterns for the Ibycus encoding were
+% generated by running the Perl script \path{ibyhyph.pl} on
+% Dimitrios Filippou's \path{GRAhyph4.tex}, which can be found in the
+% CTAN directory \path{language/hyphenation/elhyphen}. This is an
+% improved set of hyphenation patterns for ancient Greek with LGR encoding;
+% Babel does not currently use it by default.
+%
+% Dimitrios Filippou's improved hyphenation patterns discover far more
+% hyphenation points than the default Babel patterns, and are more
+% accurate, especially for compound words.
+% You will notice that there are more hyphenation
+% points right after the first letter of words beginning
+% with a vowel + consonant + vowel. Some may find such hyphenations
+% surprising, but they are legal, according to the rules for hyphenation
+% of Greek, ancient and modern; see the account by Yannis Haralambous:
+% `From Unicode to Typography, a Case Study: the Greek Script'
+% \path{<http://omega.enstb.org/yannis/pdf/boston99.pdf>}, pp~18f.
+% If you find these hyphenation points ugly, issue the command
+% \begin{verse}
+% |\def\ibycushyphenmins{2 2}|
+% \end{verse}
+% after loading of Babel in order to suppress them.
+%
+% Filippou's patterns also include legal hyphenation points
+% immediately before the last letter of a word. However, the
+% Ibycus-Babel interface suppreses them, since they are not only ugly
+% but also of little practical use.
+%
+% Please contact Peter Heslin if you come across any words that
+% Ibycus hyphenates differently from the corresponding LGR-encoded
+% patterns (except for the suppressed hyphenation before the last
+% letter of a word).
+%
+%
+% \section{Problems and deficiencies}
+% \begin{itemize}
+% \item After a sequence such as
+% \begin{verse}
+% |\selectlanguage{ibycus}| \\
+% \textit{Greek text\dots} \\
+% |\selectlanguage{|\textit{anything}|}| \\
+% \end{verse}
+% the font family is changed to the default roman typeface,
+% just as after |\rmfamily|. This can be avoided by selecting
+% the language |ibycus| only within a group or environment,
+% or by using the commands |\ibygr| or |\foreignlanguage|.
+% \item The command |\setgreekfontscale| has no effect
+% when the Ibycus fonts are already in use;
+% this situation is, however, rather unlikely in the preamble.
+% \end{itemize}
+%
+%
+% \section{Changes since version 1.5}
+% The names of several commands and environments have been changed:
+%
+% \begin{center}
+% \begin{tabular}{ll}
+% Version 1.5: & Version 2.4 \\ \hline
+% \cmd{\gk} & \cmd{\ibygr} \\
+% \texttt{greek} (environment) & \texttt{ibycus} \\
+% \cmd{\ibylatintext} & \cmd{\latintext} \\
+% \cmd{\dagger} & \cmd{\sdagger}
+% \end{tabular}
+% \end{center}
+% Furthermore, hyphenation before the last letter of a word is now
+% suppressed by default.
+%

+%
+%
+% \section{The Implementation}
+% \subsection{The \texttt{.ldf} file for use with babel}
+%
+% When the \TeX\ engine used is not an \eTeX, we issue an appropriate warning:
+% \begin{macrocode}
+%<*ibycus>
+\ifx\eTeXversion\@undefined
+ \PackageError{ibycus-babel}{%
+ The TeX engine used by LaTeX \MessageBreak
+ does not provide the the eTeX extensions.\MessageBreak
+ This may cause wrong hyphenation\MessageBreak
+ in mixed Latin/Greek paragraphs}
+ {Proceed, with fingers crossed...}
+\fi
+% \end{macrocode}
+%
+% The macro |\LdfInit| takes care of preventing that this file is
+% loaded more than once:
+% \begin{macrocode}
+\LdfInit{ibycus}{captionsibycus}
+% \end{macrocode}
+% When this file is read as an option, i.e., by the |\usepackage|
+% command, \texttt{ibycus} could be an `unknown' language in
+% which case we have to make it known. So we check for the
+% existence of |\l@ibycus| to see whether we have to do
+% something here:
+% \begin{macrocode}
+\ifx\undefined\l@ibycus
+ \@nopatterns{Ibycus}
+ \adddialect\l@ibycus0\fi
+% \end{macrocode}
+%
+% We declare a command |\ibygr| and an environment |ibycus| to make
+% entering of Greek text easier, as compared with Babel's macros:
+% \begin{macrocode}
+\DeclareRobustCommand{\ibygr}[1]{\foreignlanguage{ibycus}{#1}}
+\newenvironment{ibycus}%
+ {\begin{otherlanguage}{ibycus}}{\end{otherlanguage}}%
+% \end{macrocode}
+%
+% A command is provided to set a scaling factor for the Ibycus fonts.
+% When the fonts are already in use, the command has no effect.
+% We make sure that it can be used only in the preamble, even though this
+% does not really make sure that the fonts have not yet been loaded.
+% \begin{macrocode}
+\newcommand*{\setgreekfontscale}[1]{%
+ \def\fib@scale{#1}}
+\@onlypreamble\setgreekfontscale
+% \end{macrocode}
+% The macro |\fib@scale|, which is defined here, will be evaluated
+% in the file \texttt{ufib.fd}, see below.
+%
+% All text-editor symbols of the old package |ibycus4| are provided.
+% However, |\dagger| is named |\sdagger| now.
+% \begin{macrocode}
+\newcommand{\braceleft}{%
+ {\fontencoding{U}\fontfamily{fib}\selectfont\char'333}}
+\newcommand{\braceright}{%
+ {\fontencoding{U}\fontfamily{fib}\selectfont\char'337}}
+\newcommand{\bracketleftbt}{%
+ {\fontencoding{U}\fontfamily{fib}\selectfont\char'363}}
+\newcommand{\bracketrightbt}{%
+ {\fontencoding{U}\fontfamily{fib}\selectfont\char'367}}
+\newcommand{\sdagger}{%
+ {\fontencoding{U}\fontfamily{fib}\selectfont\char'375}}
+\newcommand{\dbldagger}{%
+ {\fontencoding{U}\fontfamily{fib}\selectfont\char'376}}
+% \end{macrocode}
+%
+% Finally, the code to integrate the pseudo-language Ibycus into Babel.
+% We start with the default values of |\lefthyphenmin| and |\righthyphenmin|.
+% \begin{macrocode}
+\providehyphenmins{ibycus}{\@ne\tw@}
+\def\captionsibycus{}
+\def\dateibycus{}
+% \end{macrocode}
+% |\latintext| needs to be changed slightly, as compared with the
+% default definition from the Babel kernel. The macro
+% must not only switch back to the default Latin font encoding;
+% it must also switch back to an appropriate font \emph{family}, since the family
+% is always changed to |fib| within the Greek passages.
+% \begin{macrocode}
+\DeclareRobustCommand{\latintext}{%
+ \fontencoding{\latinencoding}\fontfamily{\rmdefault}\selectfont
+ \def\encodingdefault{\latinencoding}}
+% \end{macrocode}
+% Should we save and restore the actual family name,
+% instead of simply forcing |\rmdefault|?
+% \begin{macrocode}
+\DeclareRobustCommand{\ibycustext}{%
+ \fontencoding{U}\fontfamily{fib}\selectfont
+ \def\encodingdefault{U}}
+\DeclareRobustCommand{\textibycus}[1]{\leavevmode{\ibycustext #1}}
+\addto\extrasibycus{\ibycustext}
+\addto\noextrasibycus{\latintext}
+\addto\extrasibycus{%
+ \babel@savevariable{\lccode`\(}\lccode`\(=`\(%
+ \babel@savevariable{\lccode`\)}\lccode`\)=`\)%
+ \babel@savevariable{\lccode`\=}\lccode`\==`\=%
+ \babel@savevariable{\lccode`\|}\lccode`\|=`\|%
+ \babel@savevariable{\lccode`\`}\lccode`\`=`\`%
+ \babel@savevariable{\lccode`\'}\lccode`\'=`\'%
+ \babel@savevariable{\lccode`\+}\lccode`\+=`\+}
+\ldf@finish{ibycus}
+%</ibycus>
+% \end{macrocode}
+%
+% \subsection{The \texttt{.fd} file}
+% We provide a correct \texttt{fd} file of our own for the Ibycus font family,
+% instead of relying on the weird file from the Ibycus4 collection,
+% and we use only those fonts, that exist also in Postscript format.
+% \begin{macrocode}
+%<*ufib>
+\ifx\aliasfont\@undefined\else\ifx\aliasfont\relax\else
+% \end{macrocode}
+% This piece of code is executed with V\TeX\ only.
+% It enables the use of the artificially slanted font.
+% \begin{macrocode}
+ \begingroup
+ \catcode32=10 %
+ \aliasfont fibo84 = fibr84 slant 167 %
+ \endgroup
+\fi\fi
+% \end{macrocode}
+% \begin{macrocode}
+\expandafter\ifx\csname fib@scale\endcsname\relax
+ \let\fib@@scale\@empty
+\else
+ \edef\fib@@scale{s*[\csname fib@scale\endcsname]}%
+\fi
+\DeclareFontFamily{U}{fib}{}
+\DeclareFontShape{U}{fib}{m}{n}{<-> \fib@@scale fibr84}{}
+\DeclareFontShape{U}{fib}{m}{sl}{<-> \fib@@scale fibo84}{}
+\DeclareFontShape{U}{fib}{b}{n}{<-> \fib@@scale fibb84}{}
+\DeclareFontShape{U}{fib}{m}{it}{<-> ssub * fib/m/sl}{}
+\DeclareFontShape{U}{fib}{bx}{n}{<-> ssub * fib/b/n}{}
+%</ufib>
+% \end{macrocode}
+%
+% \Finale
+%
+% \iffalse
+%
+% The next line of code prevents DocStrip from adding the
+% character table to the generated files(s).
