+\maketitle
+\begin{abstract}
+\noindent
+The present article is an updated view of all available tools (fonts,
+systems and more) for typesetting Greek texts with \TeX\slash
+\LaTeX. Unlike the early days of Greek \TeX\slash \LaTeX, when the
+available tools were limited, users now have an abundance of tools
+available to them. In addition, the emergence of  Unicode-aware
+systems such as  \XeTeX\ and \luaTeX{} has allowed for a major
+breakthrough in the world of \TeX: the use of Open\-Type and system
+fonts (i.e., fonts used by the operating system of the computer) for
+typesetting Greek texts.  
+\end{abstract}

+\section{Down history lane}
+In 1994, the second author of the present article wrote a summary of
+all tools available at that time for typesetting Greek texts with
+\TeX\slash \LaTeX.  That document was posted in the newsgroup
+\url{comp.text.tex}, and was immediately archived in {\small
+  CTAN}~\cite{fili:comp}. A few months later, the same document found
+its way in the newsletter of {\small NTG}, the Dutch {\small
+  LUG}~\cite{fili:maps}. In the summer of  1996, the first author
+wrote an updated summary of Greek \TeX\slash \LaTeX\
+tools~\cite{dima:ctan}.  Twenty years later, it is high time we
+produced an updated summary and review of the \emph{current} \TeX-like
+tools available to those who wish to typeset nice Greek documents.   
+
+Both reports followed the same format roughly and the presentation of
+tools for Greek \TeX ing was divided into the following four sections: 
+\begin{description}
+\item [fonts] both freely available and commercial ones;
+\item [systems] or packages containing Greek fonts, \TeX{} macros for
+  Greek output, etc.; 
+\item [help] available at the time over the Internet to \TeX\ users; and 
+\item [future predictions] which called for a standardization of Greek
+  \TeX\slash \LaTeX\ options including the New Font Selection System
+  ({\small NFSS}), the introduction of more fonts, and more. 
+\end{description}
+Let us briefly remember what was available back then before we turn
+our attention to the future. 
+
+\subsection{Fonts}
+Before the introduction of somehow comprehensive Greek \TeX\ systems,
+fonts were the first area where big and exciting changes took
+place. Naturally, the first Greek fonts were created by the Master
+himself: Don Knuth. However, his fonts were to be used in \TeX's math
+mode.  At that time, some \TeX{}ies prepared macros that allowed for
+typesetting Greek texts using Knuth's math fonts. Hamilton Kelly went
+one step further and made a set of Greek fonts by bringing Knuth's
+lowercase Greek math characters to the upright
+position~\cite{hami:ctan}. 
+
+The first fonts for Greek text typesetting by \TeX{} those designed
+more than 25 years ago by Sylvio Levy with
+\MF~\cite{levy:tugb}. Because of encoding limitations and the lack of
+widespread Greek keyboard availability, Levy had to use a
+Latin-to-Greek transliteration scheme, with some very obvious
+correspondances, e.g., \texttt{a} for \texttt{α}, \texttt{b} for
+\texttt{β}), and some not so obvious ones, e.g., \texttt{j} for
+\texttt{θ}, \texttt{q} for \texttt{χ}, \texttt{w} for \texttt{ω}
+(although \texttt{w} resembles \texttt{ω} somewhat visually). Users
+typed in \textit{Greeklish} and it took some time and a lot of
+practice to read Greeklish input files. Especially, users who used
+accents, breathing marks or other signs and symbols for multiaccent
+(\emph{polytonic}) Ancient or Modern Greek produced an almost arcane
+file for input and processing by \TeX\slash \LaTeX.  
+
+The Levy fonts were drawn according to a historic Didot Greek font,
+but following Computer Modern metrics.  They became the basis of other
+Didot-like Greek fonts by
+Haralambous~[\ref{hara:tugb1},\,\ref{hara:tugb2}], and  by
+MacKay~\cite{mack:ctan}.  The latter had an encoding suitable for
+input from the \emph{Thesaurus Lingu\ae{} Gr\ae c\ae}.  
+
+Some non-Didot Greek fonts were also created at that time using
+\MF{}. These included Malvern~\cite{dami:ctan}, a unique sans serif
+which can be still seen on the cover of \emph{Eutypon},
+Euclid~\cite{mylo:tugb}, a Times--Elsevier Greek font family never
+released to the public, and \texttt{lbf}~\cite{fiel:ctan}, which was
+based on a beautiful 18th century Bodoni Greek design but was released
+only in 2005.  Each of these fonts used its own input Greeklish
+(Latin-to-Greek) scheme, which made the use of other fonts in the same
+document very difficult, if not impossible.  
+
+\subsection{Systems}
+Back then, when {\small PC}s were running on limited amounts of
+{\small RAM}, had floppy disk drives, one processor (rather than
+multiple cores), and {\small CPU} speed was measured in MHz (rather
+than GHz), typesetting a Greek text was almost a Herculean Labour! The
+limitations of the {\small ASCII} encoding and the lack of Greek
+keyboards outside Greece made it almost impossible to type directy in
+Greek and receive Greek output. Users had to employ various
+transliteration coding schemes in order to achieve their goals.  
+
+At that time, two separate and independent Greek\TeX\ systems were
+made available. Both systems had their positive as well as negative
+elements. Both systems were introduced almost simultaenously, had
+almost the same name, but were geared for different types of users and
+operating systems. Dryllerakis' Greek\TeX{} or \textsf{kdgreek}
+system~\cite{dryl:ctan} was a set of \TeX{} macros and \MF{} fonts
+created on a Unix platform and based on earlier work by
+Levy~\cite{levy:tugb} and
+Haralambous~[\ref{hara:tugb1},\,\ref{hara:tugb2}]. Separately,
+Moschovakis produced a \textsf{greek\-tex} system for {\small PC}
+systems running with the Greek version of {\small
+  MS-DOS}~\cite{mosc:ctan}. Moschovakis' fonts were also based on
+Levy's original \MF{} work.  Of course, these systems were not
+equivalent as each had its own formatting macros and
+fonts. Moschovakis' \textsf{greek\-tex} had some tranferability issues
+between operating systems. Still, they served well many \TeX\ users
+for several years. 
+
+In perspective, \TeX ing in Greek depended primarily on the platform
+one was using.  You opted for one of the two available systems, loaded
+extra fonts, if the in-system fonts were not of your liking, and you
+were ready to \TeX\ keeping in mind that the source code (your input
+files) might be unreadable by other \TeX\ users who were not using the
+same system like yourself. 
+
+\subsection{Help needed}
+Back then, the places to look for help were limited. There were two
+main {\small USENET} newsgroups, \url{comp.text.tex} and
+\url{comp.fonts} and some discussion lists, such as the venerable
+\url{BIT.LISTSERV.HELLAS} (the major meeting point of Greeks abroad)
+or the \texttt{ELLHNIKA} mailing list, which was set up specifically
+for answering Greek \TeX\slash\LaTeX\ questions, but had very little
+traffic.  
+
+\subsection{Future as was seen back then}
+In both the Filippou~[\ref{fili:comp},\,\ref{fili:maps}] and the
+Dimakos~\cite{dima:ctan} reports, there were expectations that the new
+\LaTeX\ scheme (at the time called \LaTeXe) would introduce the
+{\small NFSS}, the ability to write in multiple languages using the
+\textsf{babel} mechanisms, and other goodies. Dimakos~\cite{dima:ctan}
+even reported that there was an initiative in Greece to establish a
+local \TeX\ users group. Who would have thought that so many years
+later, the Greek {\small LUG} would still be alive! 
+
+That was roughly the world of Greek \TeX\slash \LaTeX\ back in the mid
+1990s. Although the entire \TeX\slash\LaTeX\ ecosystem was not
+\emph{old} or dated, some limitations had started to show, primarily
+in the area of truly multilingual inputing and file preparation. Mind
+you, some projects were already set up to explore the issue and were
+indeed the forerunners of today's system. One of these systems was
+called~Ω (Omega), the brain child of Haralambous and Plaice. (A
+version of~Ω was presented by its creators in one of the early issues
+of \emph{Eutypon}~\cite{hara:euty}.) 
+
+
+\section{From the \texttt{cb} fonts to Unicode-aware machines}
+
+So, what has happened between 1996 and 2015? Well, the changes have
+been phenomenal. One might even argue that \TeX\slash\LaTeX\ has taken
+a new life with the introduction of new \emph{machines}, new
+encodings, and new Greek fonts, of course. But, let us begin with the
+latter: the introduction of new font families, which can all be found
+in the \url{/fonts/greek} directory of any {\small CTAN} node. 
+
+\subsection{New fonts} 
+
+\paragraph{CB fonts} Following the early fonts by Levy and their
+derivatives included in Dryllerakis' and Moschovakis' systems, the
+first truly ``new'' fonts were the {\small CB} font family designed
+and implemented by Beccari~[\ref{becc:ctan}--\ref{becc:tugb2}]. These
+fonts were originally written in \MF, and they included several
+variants---Leipzig-like Greek italics, sans serifs, monospace
+(typewriter), small caps, etc.---in all \TeX\slash\LaTeX{} typical
+sizes. Samples of selected {\small CB} fonts are shown in Figure~1.   
+
+The {\small CB} fonts were quickly converted to Type1, and became the
+\emph{de facto} standard font family in the world of Greek \TeX
+ing. They were used for several years in \emph{Eutypon}, and they
+still are the default Greek fonts of \textsf{babel}. Later they were
+also integrated into Open\-Type fonts of the Computer Modern Unicode
+({\small CMU}) bundle~\cite{cmun:ctan}. Syropoulos has also integrated
+some of Beccari's CB fonts into an Open\-Type monospace font
+family~\cite{syro:umty}.   
+
+\paragraph{Kerkis} This is another family of beautiful Greek font
+created by Tsolomytis~\cite{tsol:tugb}. The serif version is based on
+Bookman, while the accompanying sans serif font is based on Avant
+Garde (Figure~1). In addition to Type1, Tso\-lo\-my\-tis produced
+versions of the fonts in True\-Type and Open\-Type formats to be used
+beyond \TeX\slash\LaTeX~\cite{tsol:kerk}. 
+
+\paragraph{Greek Font Society} Perhaps the biggest contributor and a
+rather late entry into the game has been the Greek Font Society
+({\small GFS}).  Since 2005, {\small GFS} offers for free a large
+selection of Greek font families for both \TeX\slash \LaTeX\ systems
+and in Open\-Type form. On its website
+(\url{http://www.greekfontsociety.gr}), interested users can find
+fonts like {\small GFS} Didot (a modern Didot-like variant), {\small
+  GFS} Porson, {\small GFS} Neohellenic, and
+more. Tsolomytis~\cite{tsol:labo} has created Type1 versions of most
+of {\small GFS} fonts for use with \textsf{babel} (Figure~1). 
+
+\paragraph{Other options} The {\small CTAN} directory available at
+\url{http://www.ctan.org/tex-archive/fonts/greek} is the place to look
+for a few more fonts available in \MF{} or Type1 formats. However, as
+will be seen later in this report, currently available \TeX\ machines
+have already made these fonts rather obsolete. 
+

+  \TeX\slash\LaTeX{} users starting from 1998. All these fonts exist
+  in Type1 and True\-type\slash Open\-Type formats. The verses from
+  Homer's \emph{Odyssey} were typeset at 10\,pt with 12\,pt leading.} 
+\end{figure}
+
+\subsection{Working with the old encoding}
+As mentioned above, the old Latin-to-Greek transliteration scheme that
+Sylvio Levy used with his fonts was subsequently adopted by
+Haralambous, Dryllerakis and Beccari in their respective
+fonts. Beccari's character positioning in his Greek fonts became the
+\emph{de facto} ``Local Greek'' encoding, now known as \texttt{LGR},
+and the {\small CB} bundle became the basic font set of the
+\texttt{greek} option of \textsf{babel}.   
+
+Syropoulos was the maintainer of the \texttt{greek} option of
+\textsf{babel} for several years (and he also contributed in code and
+fonts for other texts as well~[\ref{syro:tugb1},\,\ref{syro:tugb2}]).
+Starting from earlier work by Haralambous and Beccari, Filippou
+created complete sets of LGR-encoded hyphenation patterns for Ancient
+and Modern Greek~[\ref{fili:ctan},\,\ref{fili:hyph}].  
+
+Since 2013, Milde~\cite{mild:ctan1} has taken over the maintenance of
+the \texttt{greek} option of \textsf{babel}. So it is still possible
+to use \LaTeX\ with the {\small LGR} encoding. The obvious advantage
+of this approach is backwards compatibility, i.e., one can still
+continue using its old Greek \TeX\ texts.  However, as already said,
+writing Greeklish to typeset multiaccent Greek texts (such as in
+Ancient Greek) makes the input almost unreadable.   
+
+\subsection{Typing Greek for Greek}
+
+\subsubsection{The pre-Unicode way}
+In 1993, the \textsf{inputenc} package appeared to make life easier
+for those who wanted to input directly accentuated Latin characters
+like \emph{\'a}, \emph{\v a}, etc. without having to type commands
+\verb+\'a+, \verb+\v{a}+, etc. Around 1998, Syropoulos created the
+\texttt{iso-8859-7} option of \textsf{inputenc} so as to allow for
+direct input of uniaccent (\emph{monotonic}) Modern Greek. Of course,
+users had to employ also the \textsf{babel} package, which loaded the
+necessary language hyphenation patterns and macros. Writing
+multilingual texts required switching from one language to the other
+using commands such as 
+\begin{verbatim}
+\selectlanguage{...}
+\end{verbatim}
+
+Needless to say such an approach complicated the use of multilingual
+bibliography sections, indexing and other language-specific sections
+of a text. At that time, it was still possible to go the {\small
+  DVI}-to-{\small PS} and {\small PS}-to-{\small PDF} way of producing
+output, although the introduction of pdf\TeX\ helped in making things
+just a little bit faster.   
+
+All these changed when the {\small UTF}-8 (Unicode) encoding started
+surpassing the {\small ISO}-8859-7 and other encodings as the
+``go-to'' choice of \LaTeX\ users. 
+
+\subsubsection{The Unicode way}
+The introduction of the Unicode encoding ({\small UTF}-8) allowed the
+typing of ``foreign'' characters beyond the 127 characters of the old
+{\small ASCII}, or the 256 characters of the extended {\small ASCII}s
+({\small ISO}-8859-7, etc.). Actually, there are two ways to type
+Greek texts:  
+\begin{itemize}
+\item[(i)] using the combination of \textsf{babel} and \textsf{inputenc} with the \texttt{utf8} or \texttt{utf8x} options, or 
+\item[(ii)] using a Unicode-aware machine such \XeTeX{} or \luaTeX.
+\end{itemize}
+
+\paragraph{The new old way}
+Milde~[\ref{mild:ctan2},\,\ref{mild:ctan3}] has gone to great lengthts
+to provide {\small UTF}-8 support for the Greek script based on
+\emph{\LaTeX{} internal character representation} macros ({\small
+  LICR}). These macros are contained in a file named
+\texttt{lgrenc.dfu} and map all Greek characters onto a set of
+\LaTeX{} internal commands such as: 
+\begin{verbatim}
+\DeclareUnicodeCharacter{03B1}{\textalpha} % lowerecase alpha 
+...
+\DeclareUnicodeCharacter{1F00}{\accpsili\textalpha} % lowercase alpha + psili
+...
+\end{verbatim}
+A \LaTeX{} user does not have to bother with the {\small LCIR}s. All
+he\slash she has to do is to include in his\slash her preamble the
+following lines: 
+\begin{verbatim}
+\usepackage[LGR,T1]{fontenc}
+\usepackage[utf8]{inputenc}
+\usepackage[greek,english]{babel}
+\end{verbatim}
+
+The package \textsf{inputenc}, with the \texttt{utf-8} option, is for
+the recognition of Unicode Greek input (in general of any {\small
+  UTF}-8 encoded input). The package \textsf{fontspec}, with the
+\texttt{LGR} and \texttt{T1} options, ensures proper hyphenation and
+proper Greek\slash Latin encoding of the output file ({\small DVI},
+{\small PS} or {\small PDF}).  
+
+This approach is useful if one has a large library of old files to
+input although some re-encoding and conversion may be required (e.g.,
+the Greek question mark~\texttt{;} is mapped onto the Greek
+semicolon~\texttt{\raisebox{.8ex}{.}}). The user is also limited to
+\MF{} or Type1 Greek fonts, which are not so many. 
+
+\paragraph{The totally new way}
+The introduction of Unicode-aware machines like \XeTeX{} and \luaTeX{}
+changed the game completely.  Here was the opportunity to truly type
+directly in Greek and in any other language with no need to
+\emph{switch} input encodings, or to set the language one way or
+another. Users can type their texts in any language they want and the
+system will take care of all the other details. Of course, it is
+necessary to declare the language and the font families that will be
+used in the text to be produced. This adds extra flexibility because
+it allows users to request multiple fonts and even specify specific
+fonts for specific needs. 
+
+Also important is the fact that \XeTeX{} and \luaTeX{} are able to
+access the system fonts available to the user. So, users are not
+limited to the Greek Type1 fonts available via the {\small CTAN}, but
+can have access to all varieties of True\-Type or Open\-Type fonts
+there are. 
+
+Syropoulos was the first to create a small package called
+\textsf{xgreek}, with some useful \XeLaTeX{} macros for typesetting
+Greek texts with \XeLaTeX~\cite{syro:ctan}. The package
+\textsf{polyglossia} followed as potential replacement of
+\textsf{babel} for typesetting multilingual texts with \XeLaTeX{} or
+lua\-\LaTeX~\cite{char:ctan}. Filippou's Greek hyphenation patterns
+were converted into Unicode encoding and they are included in all
+standard \TeX{} distributions---thus they can be used directly by
+\XeTeX{} or \luaTeX{}. 
+
+\subsection{Asking for help}
+Are there still newsgroups in operation? Is there a {\small USENET}
+anymore? In fact {\small USENET} is still alive as ``Google Groups,''
+but who needs all these relics when the answer is just a few
+keystrokes away from the nearest available Google screen? 
+
+Beyond Google, there are multiple sources of help available to the new
+or the seasoned user. The dedicated site \url{tex.stackexchange.com}
+provides answers to all kinds of \TeX\slash\LaTeX{} questions. As
+always, questions and the answers they get vary from the very
+simplistic to the overly esoteric. Still, it is an excellent site to
+turn to for suggestions. 
+
+Another option is the {\small CTAN} itself. Now, the {\small CTAN} has
+its own web (\texttt{http}) rather than \texttt{ftp} interface and
+allows for easier access to files, {\small FAQ}s, documentation and so
+on. 
+
+Finally, there are now dozens of local and national \TeX\ users's
+groups which have their own online presence. In our case,
+$*\epsilon\phi\tau*$, the Greek {\small LUG} publishes a small journal
+called \emph{Eutypon} and has a dedicated website available at
+\url{www.eutypon.gr}. In addition, several books have become available
+documenting and explaining in Greek \TeX\ and its many derivatives. 
+
+\section{The future}
+Looking back to so many years of progress, one can say that the entire
+\TeX\ ecosystem has evolved and has adapted to a multilingual
+world. Still, there is work to be done, new fonts to be included, new
+hyphenation patterns to be added for mixed LGR and Unicode input,
+etc.\ in order to make Greek typesetting an even better experience.
