+\begin{abstract}
+ \TibTeX\ is a package offering Tibetan support for \TeX\ and
+ \LaTeXe. This package is based on earlier works by Schwartz,
+ Sparkes, Sirlin, Steiner and Preining
+ (and would not be possible without their contributions!) but in
+ contrast to those the complete retransliteration process is
+ built on the ligature functionality of \TeX\ and Metafont, thus
+ effectively eliminating the need for installing any external
+ preprocessor or $\Omega$mega.

+\section{Introduction}
+
+Support for Tibetan has been available for the \TeX\ and \LaTeX\
+user community for quite a few years thanks to the contributions of
+Ronald Schwartz, Jeff Sparkes, Dominik Wujastyk\footnote{URL:
+ \texttt{CTAN://tex-archive/language/tibetan/original/}},
+Sam Sirlin\footnote{URL:
+ \texttt{CTAN://tex-archive/language/tibetan/sirlin/}}
+and
+Beat Steiner\footnote{URL:
+ \texttt{CTAN://tex-archive/language/tibetan/steiner/}}.
+
+\begin{sloppypar}
+After studying these sources it became evident to me that these systems
+were composed mainly with a \TeX\ and \LaTeX\ user in mind who is willing
+to set up additional external software (the Latin--Tibetan
+converter/preprocessor) and who, in addition, is willing to cope with
+ decidedly ``non-\TeX-ish'' code constructs (like \verb-%%-) for marking
+Tibetan language portions. I considered it useful if external preprocessors and
+unidiomatic code could be avoided at reasonable cost for the user,
+i.\,e. without introducing loads of \verb-\ThisIsMySpecialTibetanLetter--like
+commands. In addition, I appreciated the idea of a Tibetan support that
+seamlessly fits into the \TeX\ and \LaTeXe\ world---after the typical
+\verb*-\input ...- or \verb-\usepackage{...}- declaration, the user should
+ideally write something like \verb-{\tib .bod skad.}- in order to obtain
+\hbox{\tib .bod skad.} which implies that the retransliteration engine
+is realized somewhere in the realms of \TeX\ and \LaTeX.
+\end{sloppypar}
+
+The astute observer may inject that Norbert Preining made Tibetan support
+without preprocessor available in 1997 for the $\Omega$mega system.\footnote{%
+ The $\Omega$mega home is:
+ \texttt{http://www.ens.fr/omega}. $\Omega$mega is also shipped
+ with recent versions of Thomas Esser's teTeX (URL:
+ \texttt{http://tug.org/teTeX/}), to name just one example.
+
+ Norbert Preining's adaption of Sirlin's fonts for $\Omega$mega
+ can be found at:
+ \texttt{http://www.logic.at/people/preining/tex/tex.html}.}
+%
+% <- no new paragraph here!
+%
+As long as
+the transition to Unicode and $\Omega$mega has not been completed on a
+broad basis, I consider that there is still sufficient need for a \LaTeXe-%
+based Tibetan package. If its features were also usable in plain \TeX,
+I decided not to frown.
+
+
+\subsection{Words of Thanks}
+
+Of course, there is D.\,E.\,Knuth who created \TeX\ in the first place,
+and whose article on ``The New Versions of \TeX\ and \textsf{METAFONT}''%
+\footnote{Originally published in TUGboat 10 (1989), 325--328; 11 (1990),
+ 12; studied in Knuth: \textit{Digital Typography}, 1999,
+ CSLI Publications, Stanford, California, p. 563--570.}
+ignited the initial spark for building a transliteration engine as a
+pure, if not huge ligature table.
+Ongoing discussions about Tibetan transliteration issues with Wolfgang Lipp
+in the context of the Pentaglot Project were also very helpful.
+My special thanks go to Mr.~Florian Reissinger for his patience while
+reviewing the glyph lists and his comments after proof-reading the
+test runs. The warmhearted patience and understanding support by
+\hbox{\tib .phun tshogs bde skyid.} and \hbox{\tib .byin ba.} was
+essential for finishing this project.
+
+
+\subsection{Some Technical Notes}
+
+Readers who are not interested in the internals of \TibTeX\
+can safely proceed to sections~\ref{Installation} and
+\ref{UserCommands} of this text. The following notes are intended
+for those who want to get an understanding of the workings behind
+the scenes.
+
+In \TibTeX, the Tibetan retransliteration system is based on the
+ligature mechanism located at the junction of Metafont and \TeX.
+In order to implement the
+ligature mechanism Sirlin's Metafont sources were rearranged completely.
+A separate coding mechanism with symbolic character codes was introduced
+so that all character interaction (numbering, ligtable programs etc.) could
+be defined on a purely mnemonic basis, thus avoiding the cumbersome
+inflexibility of a fixed numbering scheme. During this work a mistaken
+glyph was discovered which appeared \emph{twice}: a second \emph{cwa}
+({\tib cwa}) showed up in the slot of \emph{gwa} ({\tib gwa}) while
+the \emph{gwa} glyph was missing altogether. A new \emph{gwa} was
+then built using outline fragments of other glyphs.\footnote{%
+ Alas! The mistaken \emph{cwa} which wanted to be taken for
+ a \emph{gwa} even infiltrated $\Omega$mega Tibetan\dots}
+Some character definitions were then taken from Norbert Preining's
+work; I added a text symbol \textit{visarga} ({\tib :}) into the font.
+
+In a further step, the vowel bounding boxes for [\emph{e i o}] were raised
+while several duplicate [\emph{u}]s with gradually sinking bounding
+boxes were added. Vowels could then be combined with consonants
+by simple ligature and kerning instructions, effectively eliminating
+the need for any \verb-\accent--construction on the document side.
+The exact alignment of carrier consonant and vowel can now be fine-tuned
+in the ligature table (\verb-ctibligs.mf- in the \texttt{mfinput}
+directory). While most of the conventional Tibetan words can be written
+easily in \TibTeX, the system, unlike Steiner's preprocessor,
+will fail with Sanskrit input as \emph{buddha} which turns out as
+*{\tib buddha} instead of {\tib bu\V{d}{dh},}. In cases like this
+users are requested to consult the vertical stacking command \verb|\V{}{}|
+which allows explicite stacking of any desired letter combination.
+
+Finally, a style file was created (\texttt{ctib.sty}) which provides
+the user interface to the Tibetan script and related commands. The
+style file calls font definition files which were created for accommodating
+future extensions like new script styles and typefaces.
+
+In early summer 2001, contact with Sam Sirlin was renewed, who had
+released the version 6.0 of his Tibetan package in the meantime.
+A major feature was the greatly enriched collection of glyphs
+(additional ligatures, letter elements for combining new and
+rare letters, diacritical marks, etc.) which was then made
+available to \TibTeX.
+
+\section{Installation\label{Installation}}
+
+Installation of this software package is straightforward:
+The installation procedure depends on the nature of the actual
+\TeX\ system. The directory tree of e.\,g., teTeX is different
+from the emtex tree; hence the source archive
+\texttt{ctib4tex}\textit{nn}\texttt{.zip}
+features the following subdirectories the contents of which has to be
+placed into appropriate branches of the \TeX\ installation:
+\begin{itemize}
+ \item \texttt{mfinput} holds the complete Metafont sources
+ for the Tibetan fonts. The suggested path for emtex
+ users is \verb"\emtex\mfinput\ctib"; for teTeX users
+ \verb"$TEXMF/fonts/source/public/ctib" is a suitable
+ choice.
+ \item \texttt{tfm} holds all necessary font metrics files.
+ The suggested path for emtex users is \verb"\emtex\tfm\ctib";
+ for teTeX users \verb"$TEXMF/fonts/tfm/public/ctib"
+ is a suitable choice.
+ \item \texttt{texinput} holds all style files, font encoding
+ definitions etc. which are read by \TeX\ and \LaTeXe.
+ The suggested path for emtex users is
+ \verb"\emtex\texinput\ctib"; for teTeX users
+ \verb"$TEXMF/tex/latex/ctib" is a suitable choice.
+ \item \texttt{doc} contains the documentation (the document
+ which you are reading right now). It can be placed
+ in \verb"\emtex\doc\ctib" (for emtex users) or
+ \verb"$TEXMF/doc/latex/ctib" (for teTeX users).
+\end{itemize}
+
+It may become necessary to rehash the directory database of the
+\TeX\ system. When in doubt, consult your system administrator or
+local \TeX\ wizard.
+On teTeX systems, the command \texttt{texhash} will perform this service.
+
+
+\section{User Commands\label{UserCommands}}
+
+\LaTeXe\ users activate Tibetan support for their documents via a
+\verb-\usepackage- declaration
+\begin{verbatim}
+ \documentclass[a4paper,11pt]{article}
+ \usepackage{ctib}
+\end{verbatim} in the preamble of the document, while
+\TeX\ users activate Tibetan support for their documents via an
+\verb*-\input - declaration
+\begin{verbatim}
+ \input ctib
+\end{verbatim} in the beginning of the document. The only command
+necessary is \verb-\tib- which switches to Tibetan:
+
+\exa
+ This is Tibetan:\\
+ {\tib \swasti. .bod skad.}
+\exb
+ \begin{verbatim}
+ This is Tibetan:\\
+ {\tib \swasti. .bod skad.}
+ \end{verbatim}
+\exc
+
+The \textit{tsheg} is generated automatically after every syllable
+and can be inhibited by the command \verb|\notsheg|.
+\marginpar{%
+ The most important diacritics:
+
+ \textit{tsheg} inhibition via \texttt{\char92 notsheg}.
+
+ \texttt{.} $\rightarrow$ {\tib .}\\[1.2ex]
+ \texttt{,} $\rightarrow$ {\tib ,}\\[1.2ex]
+ \texttt{:} $\rightarrow$ {\tib :}\\[1.2ex]
+ \texttt{!} $\rightarrow$ {\tib !}\\[1.2ex]
+
+ \raggedright
+ \texttt{@} $\rightarrow$ {\tib @}\\
+
+}
+So, \verb|\tib go| creates {\tib go} whereas \verb|\tib go\notsheg|
+creates {\tib go\notsheg}. The intersentence space after sentences
+ending in \textit{k, g} is created by \verb|\K| which removes the
+\textit{tsheg} at the same time. Additional \textit{tsheg}s are
+produced by commata \verb|,| while the full stop \verb|.| generates
+the \textit{shad}, the exclamation mark \verb-!- generates a
+\textit{tsheg shad} and the colon \verb|:| produces a
+\textit{visarga}. \verb|\swasti| can also be abbreviated as
+\verb|@|. See also table~\ref{SpecialDiacritics} for a fairly complete
+overview of available special symbols.
+
+Stacks of consonants used for expressing Sanskrit words are not necessarily
+contained in the basic glyph collection of \TibTeX. They can, however,
+be generated easily with the \verb|\V{}{}|command (\texttt{V} like
+\textit{vertical}). An abbreviation exists also for \emph{om} which is
+\verb|\om|.
+
+\exa
+ {\tib \om, ma nxi pa\V{de}{ma}
+ \hung \hrih:}
+
+ Abbreviations exist:
+ {\tib \dme\ \ai.}
+\exb
+ \begin{verbatim}
+ {\tib \om, ma nxi pa\V{de}{ma}
+ \hung \hrih:}
+
+ Abbreviations exist:
+ {\tib \dme\ \ai.}
+ \end{verbatim}
+\exc
+
+
+\subsection{Transliteration Table}
+
+Unlike with Steiner's and Preining's systems, there is only one
+transliteration model available; at present the user has to accept
+what the system offers. Please consult the following tables for
+an overview of available symbols. Note: symbols which could be added
+with this version thanks to Sam Sirlin's recent work on Tibetan
+fonts were \fbox{framed} for easy identification.

+\subsection{Known Transliteration Problems\label{TransliterationProblems}}
+
+The transliteration services of \TibTeX\ are coded in the ligature
+table of the font implying that these services know a lot about adjacent
+letters but know next to nothing about Tibetan syllables. The approach
+follows thus always a ``first match'' and not a ``correct match'' method.
+It is hence possible that consonant clusters are converted to Tibetan
+glyphs in a manner which was not intended by the writer. The hyphen
+\verb|-| helps solve these ambiguities:
+
+\exa
+ The syllable \emph{brtsams} is \\
+ {\tib b-rtsams}, not {\tib brtsams}!
+\exb
+ \begin{verbatim}
+ The syllable \emph{brtsams} is \\
+ {\tib b-rtsams}, not {\tib brtsams}!
+ \end{verbatim}
+\exc
+
+
+\subsection{Diacritical Marks}
+
+Thanks to Sam Sirlin's work, this version of \TibTeX\ provides a
+whole range of diacritical marks; most of them can be invoked with a
+rather lengthy command name, but for some of them there is also a
+short character mnemonic. Please consult table \ref{SpecialDiacritics} on
+page~\pageref{SpecialDiacritics}.

+\section{Example}
+
+The following text, ``The Story of \emph{Yug-pa-\`can} the Brahman'',
+is blatantly stolen from Sirlin's \texttt{/doc/} directory. Some of the
+input conventions have, however, changed slightly, and so the full text
+in romanized source and Tibetan target forms is given here. Please note
+that the word and sentence spaces are not identical with those of Sirlin's
+and Steiner's systems, hence the line and paragraph layout is not completely
+identical. Modifications of input syntax are shown in the margins.

+\section{Legal Issues}
+
+\TibTeX\ is published under the GNU Public Licence. And very much like
+I did when I picked up the work of my predecessors and changed a few
+things here and there, I warmly welcome to change and improve everything,
+but then: please rename the files. If not for the sake of source protection,
+then at least for making sure that various \TeX\ installations around the
+world do not get confused.
+
+\section{Outlook and Desiderata}
+
+At the time of this writing, \TibTeX\ is actually already
+outdated as $\Omega$mega, the Unicode-capable \TeX\ successor, is
+available. Why, then, did I undergo this effort? I needed Tibetan now,
+for ongoing Mongolian lexicographical work which is all done using
+\LaTeXe\ and Mon\TeX.
+
+Though the font provided by Schwartz, Sparkes and Sirlin is already
+useful, I keep dreaming of a true Tibetan \emph{Meta}font, not just
+outlines created by GNU \texttt{fontutils}. Such a genuine metafont
+would greatly facilitate the creation of new and different typefaces,
+at least with different weights, and the few Unicode characters not
+yet covered could then be produced easily.
+
+Though this is a work slightly more targeted at $\Omega$mega than at
+\LaTeXe, I am seriously considering preparing full-fledged Native
+Language Support for the standard document formats implying that all
+captions and the date and number formats have to be translated into
+Tibetan. With transliteration services provided internally, it should
+also be possible to integrate Tibetan into the Babel system.
+
+Anyway, whatever the mistakes and the shortcomings are that have now
+crept into this Tibetan system, I can only kindly ask you to blame me,
+not my predecessors any more.
