+%
+% \section{Introduction}
+%
+% The \textsf{sudoku} package allows the user to typeset
+% sudoku\footnote{I~have seen Sudoku written as Sudoku
+% (one word) and Su Doku (two words). I don't know which of them (if
+% either) is more correct than the other. I am just using one word.}
+% puzzles.
+%
+% A~sudoku puzzle is a 9$\times$9 grid where some of the squares in
+% the grid contain numbers. The rules are simple:
+% every column can only contain the digits 1 to 9,
+% every row can only contain the digits 1 to 9 and
+% every 3$\times$3 box can only contain the digits 1 to 9.
+%
+% The puzzle derives its name from the Japanese \textit{Su}, meaning
+% number, and \textit{Doku\/} meaning singular or solitary.
+%
+% More information, including help and example puzzles, can be found
+% at \texttt{www.sudoku.org.uk}. This site also has blank sudoku grids
+% (or worksheets), but you will not need to print them from there if
+% you have this package installed.
+%
+% \section{Acknowledgements}
+%
+% I~want to thank Morten H\o gholm who took my first attempt at
+% creating a sudoku environment in \LaTeX\ and corrected all my
+% mistakes. He then gave me the help and encouragement to publish
+% it as a package.
+%
+% \section{Usage}
+%
+% \DescribeMacro{\sudokuformat}
+% This macro contains the formatting information for each number
+% in the grid. The default value is \verb|\Huge\sffamily|, which
+% gives correctly sized numbers for the default grid size, but it
+% can be changed with \verb|\renewcommand*\sudokuformat[1]{\|\meta{font}|#1}|.
+%
+% \DescribeMacro{\sudokusize}
+% This length contains the size of the grid, defaulting to \verb|10cm|.
+% It can be changed with \verb|\setlength\sudokusize{|\meta{size}|}|.
+%
+% \DescribeEnv{sudoku-block}
+% This environment draws the sudoku grid. The contents of each cell
+% in the grid are delimited by the vertical bar (\verb+|+) character.
+%
+% \DescribeEnv{sudoku}
+% This environment starts a |center| environment, then uses the
+% |sudoku-block| environment to draw the grid.
+%
+% \section{Examples}
+%
+% This should be a relatively easy puzzle to solve.
+%

+%
+% \section{Implementation}
+%
+% First initialise a couple of counters that keep track of where we are.
+% \begin{macrocode}
+\newcounter{@sudoku@row}
+\newcounter{@sudoku@col}
+% \end{macrocode}
+%
+% \begin{macrocode}
+\newcommand*\@sudoku@separator[1]{%
+ \stepcounter{@sudoku@col}%
+ \ifx#1\@sudoku@separator
+ \expandafter#1%
+ \else
+ \ifx.#1%
+ \setcounter{@sudoku@col}{-1}%
+ \addtocounter{@sudoku@row}{-1}%
+ \else
+ \put(\value{@sudoku@col},\value{@sudoku@row})%
+ {\makebox(1,1){\sudokuformat{#1}}}%
+ \fi
+ \fi
+}
+% \end{macrocode}
+%
+% \begin{macrocode}
+\begingroup
+ \catcode`\|=\active
+ \gdef\@sudoku@activate{\let|=\@sudoku@separator}
+\endgroup
+% \end{macrocode}
+%
+% Now we can draw the grid. Each 3$\times$3 box has thicker borders
+% than the rest of the grid.
+%
+% \begin{macrocode}
+\newcommand*\@sudoku@grid{%
+ \thinlines
+ \multiput(0,0)(1,0){10}{\line(0,1){9}}%
+ \multiput(0,0)(0,1){10}{\line(1,0){9}}
+ \thicklines
+ \multiput(0,0)(3,0){4}{\line(0,1){9}}%
+ \multiput(0,0)(0,3){4}{\line(1,0){9}}
+}
+% \end{macrocode}
+%
+% The default font is a huge, sans serif font.
+% \begin{macrocode}
+\newcommand*\sudokuformat[1]{\Huge\sffamily#1}
+% \end{macrocode}
+%
+% The grid defaults to a 10 centimetre square.
+% \begin{macrocode}
+\newdimen\sudokusize
+\setlength\sudokusize{10cm}
+% \end{macrocode}
+%
+% Make the size of each square $1/9$ of the size of sudoku grid.
+% \begin{macrocode}
+\newenvironment{sudoku-block}{%
+ \catcode`\|=\active
+ \@sudoku@activate
+ \setcounter{@sudoku@col}{-1}%
+ \setcounter{@sudoku@row}{8}%
+ \setlength\unitlength{.111111\sudokusize}%
+ \begin{picture}(9,9)%
+ \@sudoku@grid\@sudoku@grab@arguments
+ }{\end{picture}}
+% \end{macrocode}
+%
+% As we change the \verb|catcode| of \verb+|+ inside the environment,
+% under normal \TeX\ we can't just use such an environment as an argument
+% of another command. This can be solved by using e\TeX\ as engine for
+% \LaTeX, which is what all the major distributions do currently.
+% \begin{macrocode}
+ \begingroup
+ \@ifundefined{eTeXversion}{\endgroup
+ \def\@sudoku@grab@arguments#1{%
+ \ifx#1\@sudoku@separator
+ \expandafter#1%
+ \else
+ \PackageError{sudoku}{%
+ Sudoku puzzles are not allowed in the arguments\MessageBreak
+ of other commands}{%
+ Either fix this in your source (possibly using the `lrbox'
+ environment) or use an eTeX based LaTeX format}
+ \fi
+ }%
+ }{\endgroup
+ \def\@sudoku@grab@arguments#1.#2.#3.#4.#5.#6.#7.#8.#9.{%
+ \scantokens{#1.#2.#3.#4.#5.#6.#7.#8.#9.}}%
+ }
+% \end{macrocode}
+%
+% The |sudoku| environment simply calls the |sudoku-block|
+% environment inside a |center| environment.
+% \begin{macrocode}
+\newenvironment{sudoku}{%
+ \begin{center}%
+ \begin{sudoku-block}}{\end{sudoku-block}\end{center}}
+% \end{macrocode}
