+%
+%    \section{The Thai language}
+%
+%    The file \file{\filename}\footnote{The file described in this section has 
+%    version number \fileversion\ and was last revised on \filedate.  The
+%    original author was Surapant Meknavin, and it was composed into
+%    \file{\filename} and maintained by Theppitak Karoonboonyanan
+%    (\texttt{thep@linux.thai.net}).} 
+%    defines language-specific macros for Thai language.
+%
+%    \subsection{Input encoding}
+%
+%    Thai documents supported by this language definition can be encoded in
+%    either TIS-620 (ISO/IEC 8859-11) or UTF-8 with the aids of the
+%    \texttt{inputenc} package.
+%
+%    \DescribeMacro{\thaitext}
+%    \DescribeMacro{\latintext}
+%      The commands |\thaitext| and |\latintext| can be used to switch to Thai
+%      or Latin fonts.  These are declarations.
+%
+%    \DescribeMacro{\textthai}
+%    \DescribeMacro{\textlatin}
+%      The commands |\textthai| and |\textlatin| both take one text argument
+%      which is then typeset using the requested language settings.
+%
+%    \DescribeMacro{\textpali}
+%      The command |\textpali| takes one text argument which is then typeset
+%      using Thai font, with special shapes for certain characters, such as
+%      descender-less Yo Ying and Tho Than, as required by usual Pali-Sanskrit
+%      transliteration.
+%
+%    \subsection{Word breaks}
+%
+%    Thai is written continuously without word delimitors.  The word boundary 
+%    analysis is considered too complicated for rule-based approaches. 
+%    Most available good-quality word analysis tools employ special matching
+%    algorithms against pre-defined dictionaries.  Some even use
+%    statistics-based contextual analysis to resolve ambiguities.  Therefore,
+%    no good hyphenation pattern is found to be comparable with those tools
+%    yet.  
+%
+%    \DescribeMacro{\wbr}
+%      What provided here for the word boundary problem is the |\wbr| command
+%      for separating words.  It delimits words without taking physical space,
+%      so that the \TeX\ typesetter still wraps lines at word boundary like
+%      when it typesets English text.
+%
+%    Therefore, one can preprocess their Thai document using Thai word analysis
+%    tools which automatically insert the |\wbr| commands between words, such
+%    as:
+%      \begin{itemize}
+%      \item \emph{cttex} by Vuthichai Ampornaramveth
+%      \item \emph{swath} by Phaisarn Charoenpornsawat, now maintained by Thai 
+%            Linux Working Group, which can be downloaded from:\\
+%            \texttt{ftp://linux.thai.net/pub/thailinux/software/swath}
+%
+%            To compile \emph{swath}, you need \emph{libdatrie} as the
+%            dependency, which is provided under the \emph{libthai} project:\\
+%            \texttt{ftp://linux.thai.net/pub/thailinux/software/libthai}
+%      \end{itemize}
+%
+%    \subsection{Thai paragraph}
+%    \label{thai-paragraph}
+%    Generally speaking, Thai paragraph uses the same rule as in English.
+%    However, there are some differences, such as how to start the paragraph
+%    in a new chapter or section.
+%
+%    \DescribeEnv{thaiindentfirst}
+%    As suggested by English writing guideline, the first paragraph in each 
+%    section shall not be indented.  However, for Thai language, indenting the
+%    first paragraph is more popular and widely suggested.  The option 
+%    \Lopt{thaiindentfirst} can be used to control this behavior.
+%
+%    \subsection{Thai numbering}
+%    \label{thai-numbering}
+%
+%    Some certain Thai documents use Thai digits instead of Arabic.
+%    And Thai alphabetic numbering is also commonly used for appendices.
+%    This file provides a number of numbering styles that can be applied 
+%    to \LaTeX\ |\pagenumbering| command:
+%
+%      \begin{itemize}
+%      \item |\thainum| for plain Thai digits
+%      \item |\thaibracenum| for Thai digits in parentheses
+%      \item |\thaialph| for Thai alphabetic numbering, using a reduced set
+%            (with three alphabets skipped: Kho Khuat, Kho Khon and Kho Rakhang)
+%      \item |\thaiAlph| for Thai alphabetic numbering, using the full set
+%            (with full alphabet set, plus two semi-vowels, Ru and Lu, in the
+%            order defined in Thai official dictionary)
+%      \end{itemize}
+%
+%    \DescribeEnv{thainumber}
+%      The above numbering styles can be automatically chosen using the 
+%      \Lopt{thainumber} option.  When this option is supplied to the \babel{}
+%      package, Thai numberings will be applied to pages, sections,
+%      enumerations, dates, etc.
+%
+% \StopEventually{}
+%
+%    \subsection{Thai language definition}
+%
+%    The macro |\LdfInit| takes care of preventing file from being
+%    loaded more than once, checking the category code of the
+%    \texttt{@} sign, etc.
+%    \begin{macrocode}
+%<*code>
+\LdfInit\CurrentOption{captions\CurrentOption}
+%    \end{macrocode}
+%
+%    When this file is read as an option, i.e. by the |\usepackage{babel}|
+%    command, \texttt{thai} will be an `unknown' language, in which
+%    case we have to make it known.  So, we check for the existence of
+%    |\l@thai| to see whether we have to do something here.
+%
+%    \begin{macrocode}
+\ifx\l@thai\@undefined
+  \@nopatterns{thai}
+  \adddialect\l@thai0\fi
+%    \end{macrocode}
+%
+%    \subsubsection{Thai character encoding}
+%
+%    In this language definition, we support TIS-620, the national standard 
+%    8-bit character encoding, and Unicode by means of \texttt{inputenc} 
+%    package.
+%
+%    The encoding has been described in terms of TIS-620 as \texttt{LTH} in 
+%    the \file{lthenc.def} file.  So, we require it.
+%
+%    \begin{macrocode}
+\InputIfFileExists{lthenc.def}%
+  {\message{Loading the definitions for the Thai font encoding}}%
+  {%
+    \errhelp{I can't find the lthenc.def file for the Thai fonts}%
+    \errmessage{Since I do not know what the LTH encoding means^^J
+      I can't typeset Thai.^^J
+      I stop here, while you get a suitable lthenc.def file}\@@end
+  }
+%    \end{macrocode}
+%
+%    The next step consists of defining commands to switch to the Thai
+%    language, for users to switch back and forth between languages.
+%
+% \begin{macro}{\thaitext}
+%    We define |\thaitext| as a declarative switch to Thai font encoding.
+%    \begin{macrocode}
+\DeclareRobustCommand{\thaitext}{%
+  \fontencoding{LTH}\selectfont%
+  \def\encodingdefault{LTH}}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\textthai}
+%    This command takes one text argument which is then typeset using Thai font 
+%    encoding.
+%    \begin{macrocode}
+\DeclareRobustCommand{\textthai}[1]{{\thaitext #1}}
+%    \end{macrocode}
+% \end{macro}
+%
+%    \subsubsection{Pali-Sanskrit Transliteration}
+%
+%    Thai script can also be used for writing Pali and Sanskrit.  Additional
+%    conventions are applied when doing so: (a) Yo Ying and Tho Than must be
+%    written without descender; (b) Phinthu is used for marking cluster;
+%    (c) Nikhahit is used as a Pali-Sanskrit consonant.  
+%
+%    (b) is inherently applicable as combining character.  So is (c), with
+%    an exception for the case in which it is combined over upper vowel
+%    (namely, Sara I), where it must be shifted to higher position.  Nikhahit
+%    shifting is implemented in the ligkern rules with the extra glyph
+%    provision in the fonts.
+%
+%    What is left here is (a).  Yo Ying and Tho Than must be converted to
+%    their descender-less variants.  The |\textpali| macro is defined
+%    for this purpose.  Note that |\wbr| commands which are normally inserted
+%    by automatic tools are ignored here, as most of such tools are not
+%    designed for Pali/Sanskrit.  Besides, Pali/Sanskrit is already space
+%    delimited.
+%
+% \begin{macro}{\textpali}
+%    This command converts all Yo Ying and Tho Than in its argument to
+%    their descender-less variations.
+%    \begin{macrocode}
+\DeclareRobustCommand{\textpali}[1]{%
+  \begingroup
+    \def\thaiYoYing{\textYoYingPali{}}%
+    \def\thaiThoThan{\textThoThanPali{}}%
+    \def\wbr{}%
+    \scantokens\expandafter{#1}\relax
+  \endgroup
+}
+%    \end{macrocode}
+% \end{macro}
+%
+%    \subsubsection{Hyphenation}
+%
+%    We define |\thaihyphenmins| macro for hyphenation parameters.  This is 
+%    one of the five macros required by \babel{}.
+%
+% \begin{macro}{\thaihyphenmins}
+%    This macro is used to store the correct values of the hyphenation
+%    parameters |\lefthyphenmin| and |\righthyphenmin|.  They are set to 11.
+% \changes{thai-1.1}{2006/07/02}{Theppitak Karoonboonyanan:
+%    Now use \cs{providehyphenmins} to provide a default value}
+%    \begin{macrocode}
+\providehyphenmins{thai}{11}
+%    \end{macrocode}
+% \end{macro}
+%
+%    \subsubsection{Captions translation}
+%
+%    We define |\captionsthai| macro for translations of strings.  This is 
+%    one of the five macros required by \babel{}.
+%
+% \begin{macro}{\captionsthai}
+%    The macro |\captionsthai| defines all strings used in the four
+%    standard documentclasses provided with \LaTeX.
+%    \begin{macrocode}

+%
+%    \subsubsection{Date}
+%
+%    Here we define |\datethai| macro for Thai date format.  This is 
+%    one of the five macros required by \babel{}.
+%
+%    First, let's define the months in Thai.
+%
+%    \begin{macrocode}

+%    \end{macrocode}
+%
+%    Thai official calendar uses Buddhist Era, the era whose start is marked 
+%    by Buddha's entry into Parinirvana.  In original form, it is a lunar 
+%    calendar.  But in Thai contemporary calendar, it is synchronized to 
+%    Gregorian calendar, with offset of 543 years back.
+%
+%    \begin{macrocode}
+\newcount\th@year
+\th@year=\year
+\advance\th@year by 543
+%    \end{macrocode}
+%
+%    Then, we come to the |\datethai| macro.
+%
+% \begin{macro}{\datethai}
+%    Thai date format is in the day-month-year order, using Buddhist Era.
+%    \begin{macrocode}
+\def\datethai{%
+  \def\today{\number\day \space \th@month\space %
+             \thaiPhoPhan.\thaiSoSala.~\number\th@year}}
+%    \end{macrocode}
+% \end{macro}
+%
+%    \subsubsection{Extra definitions for language switching}
+%
+%    Then, the last two macros required by \babel{} are |\extrasthai| and 
+%    |\noextrasthai| containing extra definitions needed for Thai language 
+%    upon switching to and out of it, respectively.
+%
+%    \begin{macrocode}
+\addto\extrasthai{\thaitext}
+\addto\noextrasthai{\latintext}
+%    \end{macrocode}
+%
+%    \subsection{Word break support}
+%
+%    As Thai script is written continuously without word delimitors, we define 
+%    |\wbr| command to mark word boundaries without taking space, so that 
+%    \TeX typesetter can wrap Thai lines at proper positions.
+%
+%    \begin{macrocode}
+\def\wbr{\hskip0pt\relax}
+%    \end{macrocode}
+%
+%    \subsection{Space stretching}
+%
+%    Since ordinary Thai text contains fewer spaces than English,
+%    the \TeX{} justification is stressed with fewer places to stretch
+%    to make the line reach the right margin.  This usually ends up with
+%    overfull lines when \TeX{} decides to include the next word to fill
+%    the space, instead of trying to manipulate spacing with appropriate
+%    amount of text.  Possible solutions to this problem include:
+%    \begin{itemize}
+%      \item \emph{Use letter spacing.}  This is a common practice in Thai
+%        publishing.  However, \TeX{} does not allow this, probably not to
+%        shag sheep.\footnote{\emph{``Men who would letterspace blackletter
+%        would shag sheep'' --- Frederick Goudy.}}
+%      \item \emph{Allow stretching between words.}  This used to be a simple
+%        hack in an old version of this module, until it was finally
+%        dropped in version 1.4b, as it was considered suboptimal.
+%      \item \emph{Allow more space stretching.}  This can be more acceptable,
+%        compared to the ragged right margin.  And it is what we do here.
+%    \end{itemize}
+%
+%    \begin{macrocode}
+\addto\extrasthai{%
+  \edef\th@restoreemstretch{\emergencystretch=\the\emergencystretch}
+  \setlength{\emergencystretch}{0.6em}}
+\addto\noextrasthai{\th@restoreemstretch}
+%    \end{macrocode}
+%
+%    \subsection{Line spacing}
+%
+%    Due to multi-level combining character stacking, Thai text lines
+%    can occupy more vertical space than English.  To prevent overlapping,
+%    \TeX{} allocates more height for lines with combining characters
+%    but not for those without.  This can cause irregular line spacing.
+%    To avoid this problem, we need to stretch the line spacing.
+%
+%    \begin{macrocode}
+\renewcommand{\baselinestretch}{1.2}
+%    \end{macrocode}
+%
+%    \subsection{Paragraph}
+%    This section provides Thai paragarph formating style as described in
+%    \S\ref{thai-paragraph}.
+%
+%    \subsubsection{\Lopt{thaiindentfirst} option}
+%
+%    If \Lopt{thaiindentfirst} is supplied in the |\usepackage| command, the
+%    first Thai paragraph in each section will be indented.  The other 
+%    paragraphs will behave as default.
+%
+%    \begin{macrocode}
+\DeclareOption{thaiindentfirst} {%
+%    \end{macrocode}
+%
+%    When switching to Thai language, point |\@afterindentfalse| to 
+%    |\@afterindentrue|, so that \LaTeX\ will never indent the first
+%    paragraph. 
+%
+%    \begin{macrocode}
+  \addto\extrasthai{%
+    \let\th@afterindentfalse\@afterindentfalse
+    \let\@afterindentfalse\@afterindenttrue
+    \@afterindenttrue
+  }
+%    \end{macrocode}
+%
+%    When switching out of Thai language, point |\@afterindentfalse|
+%    back to its original function.
+%
+%    \begin{macrocode}
+  \addto\noextrasthai{%
+    \let\@afterindentfalse\th@afterindentfalse
+  }
+}
+%    \end{macrocode}
+%
+%    \subsection{Thai numbering support}
+%
+%    This section provides Thai numbering styles as described in
+%    \S\ref{thai-numbering}: |\thainum|, |\thaibracenum|, |\thaialph| and
+%    |\thaiAlph|.
+%
+%    First, we define a macro for translating decimal digits into Thai digits.
+%
+% \begin{macro}{\thaitranslate}
+%    The |\thaitranslate| macro determines decimal digits in the argument and 
+%    convert them to Thai digit one by one, until the `|@|' terminator is found.
+%    \begin{macrocode}
+\def\thaitranslate#1{\ifx @#1%
+     \else\ifcase#1
+       \thaizero \or \thaione \or \thaitwo \or \thaithree \or \thaifour \or 
+       \thaifive \or \thaisix \or \thaiseven \or \thaieight \or \thainine
+       \else\fi
+       \expandafter\thaitranslate
+     \fi
+}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\thainum}
+%    The |\thainum| macro is to be used as a numbering style in \LaTeX\ 
+%    |\pagenumbering| command.
+%
+%    It takes a counter name and converts its value into Thai digits.  
+%    In details, it prepends the counter name with `|c@|' to access the counter 
+%    value, then calls |\@thainum| to convert it into Thai digits.
+%
+%    The |\@thainum| macro converts a number into Thai digits.  It expands the 
+%    argument into a number, terminates it with `|@|', and calls 
+%    |\thaitranslate| to convert it into Thai digits.
+%
+%    \begin{macrocode}
+\def\@thainum#1{\expandafter\thaitranslate\number#1@}
+\def\thainum#1{\expandafter\@thainum\csname c@#1\endcsname}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\thaibracenum}
+%    Similar to |\thainum|, the |\thaibracenum| macro is to be used as a 
+%    numbering style in \LaTeX\ |\pagenumbering| command.
+%
+%    It provides Thai digits numbering, surrounded by parentheses.
+%
+%    \begin{macrocode}
+\def\@thaibracenum#1{(\expandafter\thaitranslate\number#1@)}
+\def\thaibracenum#1{\expandafter\@thaibracenum\csname c@#1\endcsname}
+%    \end{macrocode}
+% \end{macro}
+%
+%    Now come to Thai alphabetic numbering, beginning with the reduced set.
+%
+% \begin{macro}{\thaialph}
+%    The |\thaialph| macro is to be used as a numbering style in \LaTeX\ 
+%    |\pagenumbering| command.
+%
+%    It converts a number not greater than 41 into Thai alphabet in the
+%    corresponding order in the reduced set.  In this set, 3 characters
+%    are skipped: Kho Khuat, Kho Khon and Kho Rakhang.
+%
+%    \begin{macrocode}
+\def\thaialph#1{\expandafter\@thaialph\csname c@#1\endcsname}
+\def\@thaialph#1{%
+  \ifcase#1\or \thaiKoKai\or \thaiKhoKhai\or \thaiKhoKhwai\or \thaiNgoNgu\or 
+    \thaiChoChan\or \thaiChoChing\or \thaiChoChang\or \thaiSoSo\or 
+    \thaiChoChoe\or \thaiYoYing\or \thaiDoChada\or \thaiToPatak\or 
+    \thaiThoThan\or \thaiThoNangmontho\or \thaiThoPhuthao\or \thaiNoNen\or 
+    \thaiDoDek\or \thaiToTao\or \thaiThoThung\or \thaiThoThahan\or 
+    \thaiThoThong\or \thaiNoNu\or \thaiBoBaimai\or \thaiPoPla\or 
+    \thaiPhoPhung\or \thaiFoFa\or \thaiPhoPhan\or \thaiFoFan\or 
+    \thaiPhoSamphao\or \thaiMoMa\or \thaiYoYak\or \thaiRoRua\or 
+    \thaiLoLing\or \thaiWoWaen\or \thaiSoSala\or \thaiSoRusi\or 
+    \thaiSoSua\or \thaiHoHip\or \thaiLoChula\or \thaiOAng\or
+    \thaiHoNokhuk\else\@ctrerr\fi}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\thaiAlph}
+%    Similar to |\thaialph|, the |\thaiAlph| macro provides Thai alphabetic 
+%    numbering with full alphabet set in the order defined in Thai official 
+%    dictionary.  So, it supports up to 44 entries.
+%
+%    \begin{macrocode}
+\def\thaiAlph#1{\expandafter\@thaiAlph\csname c@#1\endcsname}
+\def\@thaiAlph#1{%
+  \ifcase#1\or \thaiKoKai\or \thaiKhoKhai\or \thaiKhoKhuat\or \thaiKhoKhwai\or 
+    \thaiKhoKhon\or \thaiKhoRakhang\or \thaiNgoNgu\or \thaiChoChan\or 
+    \thaiChoChing\or \thaiChoChang\or \thaiSoSo\or \thaiChoChoe\or 
+    \thaiYoYing\or \thaiDoChada\or \thaiToPatak\or \thaiThoThan\or 
+    \thaiThoNangmontho\or \thaiThoPhuthao\or \thaiNoNen\or \thaiDoDek\or 
+    \thaiToTao\or \thaiThoThung\or \thaiThoThahan\or \thaiThoThong\or 
+    \thaiNoNu\or \thaiBoBaimai\or \thaiPoPla\or \thaiPhoPhung\or
+    \thaiFoFa\or \thaiPhoPhan\or \thaiFoFan\or \thaiPhoSamphao\or 
+    \thaiMoMa\or \thaiYoYak\or \thaiRoRua\or \thaiLoLing\or 
+    \thaiWoWaen\or \thaiSoSala\or \thaiSoRusi\or \thaiSoSua\or 
+    \thaiHoHip\or \thaiLoChula\or \thaiOAng\or \thaiHoNokhuk\else\@ctrerr\fi}
+%    \end{macrocode}
+% \end{macro}
+%
+%    \subsubsection{\Lopt{thainumber} option}
+%
+%    Not all Thai documents use Thai digits.  So, we support this as an 
+%    option.  If \Lopt{thainumber} option is supplied in the |\usepackage| 
+%    command, Thai digits will be used in all numberings.
+%
+%    \begin{macrocode}
+\DeclareOption{thainumber}{
+%    \end{macrocode}
+%
+%    We need to use the `|@|' character in macro implementations.  So, make it 
+%    a normal charactor.
+%
+%    \begin{macrocode}
+\catcode`\@=11
+%    \end{macrocode}
+%
+%    Since |\renewcommand| will fail if the renewed command does not exist,
+%    and we are redefining counters independently on the document class
+%    being used, we had better check for the counters' existence before
+%    redefining them.  To do so, we define a helper macro for this.
+%
+%    \begin{macrocode}
+\def\@overridecommand#1#2{\ifdefined#1\renewcommand{#1}{#2}\fi}
+%    \end{macrocode}
+%
+%    Then, set default page numbering to |thainum|, and redefine counters
+%    to |thainum|.
+%
+%    \begin{macrocode}
+\pagenumbering{thainum}
+\@overridecommand\theenumi{\@thainum\c@enumi}
+\@overridecommand\theenumii{\@thaialph\c@enumii}
+%\@overridecommand\theenumiii{\@roman\c@enumiii}

+   \@overridecommand \thefigure%
+       {\ifnum \c@chapter>\z@ \thechapter.\fi \@thainum\c@figure}}
+\@overridecommand\thefootnote{\@thainum\c@footnote}
+%    \end{macrocode}
+%
+%    For theorems, we support all custom theorem counters at once by 
+%    redefining |\@thmcounter| macro.
+%
+%    \begin{macrocode}
+\def\@thmcounter#1{\noexpand\thainum{#1}} 
+%    \end{macrocode}
+%
+%    In book class, page numberings for frontmatter and mainmatter are
+%    different.  So, redefine them.
+%
+%    \begin{macrocode}
+\@ifclassloaded{book}{%
+  % redefine page numbering for frontmatter and mainmatter
+  \def\ps@headnum{\let\@mkboth\@gobbletwo
+       \def\@oddhead{\reset@font\hfil\thepage\hfil}\let\@oddfoot\@empty
+       \let\@evenhead\@oddhead\let\@evenfoot\@empty}
+  \let\@ltxfrontmatter\frontmatter
+  \renewcommand\frontmatter%
+    {\@ltxfrontmatter\pagestyle{headnum}\pagenumbering{thaibracenum}}
+  \let\@ltxmainmatter\mainmatter
+  \renewcommand\mainmatter%
+    {\@ltxmainmatter\pagestyle{headings}\pagenumbering{thainum}}
+}{}
+%    \end{macrocode}
+%
+%    Redefine Thai date using Thai digits.
+%
+%    \begin{macrocode}
+\def\datethai{%
+  \def\today{\@thainum\day\space \th@month\space %
+             \thaiPhoPhan.\thaiSoSala.~\@thainum\th@year}
+}
+%    \end{macrocode}
+%
+%    And finish declaration of \Lopt{thainumber} option
+%
+%    \begin{macrocode}
+\relax
+}
+%    \end{macrocode}
+%
+%    Always use thaialph as counter for appendix
+%
+%    \begin{macrocode}
+\@ifclassloaded{book}{%
