+% 
+% \section{Y tableau?}
+% 
+% At present there exist two packages with which one can draw Young tableaux: \textsf{young} and
+% \textsf{youngtab}.  As the latter is explicitly an alternative to the former, they do not overlap
+% very much except in what they eventually produce.  Between them, they define the following three
+% basic constructions of Young tableaux:
+% 
+% \begin{itemize}
+%  \item An environment with array-style syntax;
+%  
+%  \item A short-form macro;
+%  
+%  \item An even shorter-form macro for drawing Young diagrams (having nothing inside the boxes).
+% \end{itemize}
+% 
+% In this package we also implement these methods.  However, we aim to take them as far as possible
+% so that the conceivable needs of a mathematician making serious use of Young tableaux can be met
+% with as little effort as possible on their part (and, thus, great effort on the part of this
+% author).  In writing this package we pursued the following major goals:
+% 
+% \begin{itemize}
+%  \item The syntax should be as convenient as possible.  The \textsf{young} package makes
+%  unfortunate use of the |\cr| delimiter for lines in an array, which is nowhere to be seen in
+%  modern \LaTeX\ and is likely unfamiliar to casual, young writers.  The \textsf{youngtab} package
+%  requires the author to define individual, separate macros to draw items requiring more than one
+%  token to represent in \TeX.  That is, if a cell of a tableau is to contain the expression $n +
+%  1$, then one must place it into an auxiliary macro.  Also, the same command, |\young|, delimits
+%  its contents with parentheses |(...)| rather than braces |{...}|.
+%  
+%  \item The package should make no assumptions about the intentions of the user.  In particular,
+%  esoteric constructions such as skew tableaux and disconnected tableaux are not in principle any
+%  more difficult to draw, and should be no more difficult to write.
+%  
+%  \item Tableaux should support totally arbitrary decoration.  We took this to mean that they
+%  should be easily colored; this possibility allows the depiction of tableaux within tableaux, an
+%  application which was specifically requested of the author (and was the original reason for
+%  writing this package).
+%  
+%  \item Configuration should be easy and plentiful.  The \textsf{young} package has none, while
+%  \textsf{youngtab} package uses a strange syntax.  Now that \textsf{keyval} is available there is
+%  no excuse for not providing a keyword-driven user interface to options controlling all aspects of
+%  the appearance of tableaux.
+%  
+%  \item Interoperability with all the common environments.  In particular, since this is a
+%  mathematics package, it should work properly in the AMS environments, and since it is an
+%  array-based package it should work properly in array environments.
+% \end{itemize}
+% 
+% We believe the package achieves all these things.  There should be nothing that one would want to
+% do with Young tableaux that cannot be accomplished in the obvious way using the commands given
+% below.
+
+% 
+% \section{User commands}
+% \label{s:user commands}
+% 
+% We provide three commands for drawing Young tableaux and diagrams.  Each one is convenient for
+% slightly different purposes and each supports various operations more or less easily than the
+% others.
+% 
+% \subsection{The \texttt{ytableau} environment}
+% \label{ss:the ytableau environment}
+% 
+% \DescribeEnv{ytableau}
+% The |ytableau| environment is the core drawing engine for this package.  It may be called as
+% follows (similarly to \textsf{young}):
+% 
+% \bigskip\noindent
+% \quad |\begin{ytableau}|\oarg{general formatting}
+% 
+% \smallskip\noindent
+% \qquad   \meta{entry} |&| |*|\parg{color name} \meta{entry} |& ... \\|
+% 
+% \smallskip\noindent
+% \qquad   |...|
+% 
+% \smallskip\noindent
+% \quad |\end{ytableau}|
+% 
+% \bigskip\noindent
+% The result is an array of boxes separated by lines of width |0.4pt| (not tunable, and not affected
+% by outside influences), each containing the entries specified in the environment.
+% 
+% Each \meta{entry} is typeset in math mode (by default, but text mode is possible) and the entries
+% are horizontally and (mostly) vertically
+% centered in their box.  In fact, the entries are treated as though they consist of a single line
+% of text, and the baselines of all the entries in a row are aligned with each other for a
+% consistent appearance.  The environment may appear in or out of math mode without any ill effect
+% (and without any effect on the contents).
+% 
+% \DescribeMacro{\none}
+% An entry may be omitted by writing |\none|, which prevents the drawing of a frame but places an
+% invisible box of the correct dimension inside the entry.  Thus, one may create a tableau
+% ``starting'' at an offset or even a ``tableau'' consisting of several disconnected regions.  One
+% can actually get things into these ``empty'' boxes by passing an optional argument to |\none|.
+% 
+% The \meta{color name} can be any color name familiar to the package \textsf{xcolor}, or (of
+% course) user-defined.  The background of this box will be drawn in that color; by default, if no
+% color is given the background is \emph{transparent}, which probably means white, unless the
+% tableau is somehow overlaid on something else (see \ref{ss:chaining}).
+% 
+% The \meta{general formatting} is simply \TeX\ material which is placed in front of each
+% \meta{entry}.  It can also contain a \meta{color name}, which is overridden by those specified
+% individually.
+%
+% \subsection{The \texttt{ytableaushort} command}
+% \label{ss:the ytableaushort command}
+% 
+% \DescribeMacro{\ytableaushort}
+% This command (however ironically named) allows inline specification of a tableau:
+% 
+% \bigskip\noindent
+% \quad |\ytableaushort| \oarg{general formatting} |{|\meta{line}|,|\meta{line}|,...}|
+% 
+% \bigskip\noindent
+% where \meta{general formatting} is as before, and each \meta{line} is a sequence of tokens
+% representing entries in the tableau, similarly to \textsf{youngtab}.  However, it is possible to
+% include complex entries by surrounding them in |{...}|.  This command internally reduces its
+% functioning to |ytableau|, so the entries may contain colors and in general behave exactly as
+% described above.
+% 
+% \subsection{The \texttt{ydiagram} command}
+% \label{ss:the ydiagram command}
+% 
+% \DescribeMacro{\ydiagram}
+% This command draws Young diagrams somewhat in the manner of \textsf{youngtab}:
+% 
+% \bigskip\noindent
+% \quad |\ydiagram| \oarg{general formatting} |{[|\meta{offset}| +]|\meta{number}|,...}|
+% 
+% \bigskip\noindent
+% producing an array of \emph{identical} boxes (empty by default), each row having \meta{number} in
+% it with \meta{offset} blank boxes preceding (\meta{offset} is optional but, when provided, is not
+% written with |[...]|.  Thus, a typical invocation might be
+% \begin{center}
+% |\ydiagram{2 + 1, 3, 1}|.
+% \end{center}
+% Both \meta{offset} and \meta{number} may be any
+% \TeX\ expressions evaluating to the textual representation of a number (e.g.\ 6 or
+% |\thecountername|, but not just |\countername|).  The boxes can be colored or filled with a single
+% expression by means of \meta{general formatting}.
+%
+% \subsection{Chaining}
+% \label{ss:chaining}
+% 
+% The coloring facility for |\ydiagram| is not very interesting as-is.  Thus, the package allows for
+% the augmentation of several diagrams in the following manner:
+% 
+% \bigskip\noindent
+% \quad |\ydiagram| \meta{arguments} |*| \meta{arguments} |* ...|
+% 
+% \bigskip\noindent
+% produces a \emph{single} Young diagram obtained by layering the ones specified by the various
+% \meta{arguments} from left (on top) to right (at the bottom).  In fact, one can even write
+% 
+% \bigskip\noindent
+% \quad |\ytableaushort| \meta{tableau arguments} |*| \meta{diagram arguments} |* ...|
+% 
+% \bigskip\noindent
+% where first a Young tableau is constructed according to the initial set of arguments, then all
+% subsequent arguments are passed to |\ydiagram|, with the result layered from left to right.  This
+% allows the construction of arbitrary color patterns with arbitrary contents.
+% 
+% This operation is not possible with |\begin{ytableau}...\end{ytableau}| since the
+% |\end| command obscures the following text from the internally-called |\endytableau| command.  If
+% you want to chain a |ytableau|, instead write it in the \TeX\ style |\ytableau...\endytableau|. 
+% Unfortunately it is not possible to work around this.
+% 
+% \section{Package options}
+% The package accepts the following options:
+% \begin{itemize}
+%  \item \DescribeMacro{boxsize}
+%  |boxsize|=\meta{dimension}.  This manually sets the height (and width, which is the same)
+%  of boxes in all tableaux to \meta{dimension}.  If you change the size and want to get back to
+%  the default (1.5em), just say |boxsize = normal|.
+%  
+%  \item \DescribeMacro{smalltableaux} \DescribeMacro{nosmalltableaux}
+%  |smalltableaux|/|nosmalltableaux|.  The first option makes the box size quite small;
+%  indeed, small enough to fit a |$f$| precisely, as computed by careful eyeballing tests. 
+%  It also passes |\scriptstyle| to each box, which as usual can be overridden if you wish (but you
+%  don't). The second option returns things to how they were.
+%  
+%  \item \DescribeMacro{aligntableaux} \DescribeMacro{centertableaux}
+%        \DescribeMacro{nocentertableaux}
+%  |aligntableaux|=\meta{alignment}/|centertableaux|/|nocentertableaux|.  The first argument
+%  allows any of |top|, |center|, or |bottom|.  With |top|, the tableaux are all aligned on the
+%  baseline of their top row, with |bottom| they are aligned on the baseline of their bottom row,
+%  and |center| centers them (they correspond to |\vtop|, |\vbox|, and |\vcenter|).  The other two
+%  arguments are semantically pleasing shorthand for |aligntableaux = center| and
+%  |aligntableaux = top|.
+% 
+%  \item \DescribeMacro{textmode} \DescribeMacro{mathmode}
+%  |textmode|/|mathmode|.  The former sets all the boxes in text mode, and the latter returns
+%  to math mode (the default).
+% \end{itemize}
+% It may not be useful to set these options globally, so we provide a macro for changing each of
+% these parameters ``on the fly'':
+% 
+% \DescribeMacro{\ytableausetup}
+% Takes all of the above options and acts on them, setting parameters for all subsequent
+% tableaux.  The assignments are global with respect to \TeX\ nestings.
+%
+% One can also pass options to \textsf{xcolor} when calling \textsf{ytableau}, but these options
+% are not further configurable through |\ytableausetup|.
+% 
+% \section{Samples}
+% 
+% Note that the option settings are persistent.

+%  \subsection{\texttt{ytableau} environment}
+% 
+% \begin{environment}{ytableau}
+% The core tableau-drawing environment.  The first argument, which is optional, is just
+% ``formatting'' pasted on to each entry.  The contents are an |\halign|-style array; if an entry
+% begins with |*|\parg{color}, then the background of that box is colored.
+%    \begin{macrocode}
+\newenvironment{ytableau}[1][]
+{%
+ \leavevmode%
+%    \end{macrocode}
+% The point of this obtuse command is to produce a syntactically balanced pair of braces |{}| which
+% semantically is equivalent to just an open brace |{|. This is required to support tableaux nested
+% inside other alignments because |\halign| does not recognize |\bgroup|...|\egroup| as designating
+% a nesting! (We will use this fact later, actually.) But we can't just write |{| and (in
+% |\endytableau|) |}| either.
+%    \begin{macrocode}
+ {\iffalse}\fi%
+  \global\setbox\ytableau@thistableau=\hbox\bgroup$%
+   \m@th%
+   \setlength{\fboxrule}{\ytableau@boxframe}%
+   \setlength{\fboxsep}{0pt}%
+%    \end{macrocode}
+% Despite the alignment requirements, we set the tableau top-aligned so that it can be easily
+% chained.  This will get fixed before we print it, though.
+%    \begin{macrocode}
+   \vtop\bgroup%
+%    \end{macrocode}
+% I hate |\cr|, let's use the \LaTeX\ convention.
+%    \begin{macrocode}
+    \let\\=\ytableau@cr%
+%    \end{macrocode}
+% Lines and columns should abut, accounting for the fact that each entry is framed.
+%    \begin{macrocode}
+    \offinterlineskip%
+    \openup-\fboxrule%
+    \tabskip=-\fboxrule%
+%    \end{macrocode}
+% Now we begin the |\halign|.  Each entry is passed as an argument to our box-building function,
+% but we can't just write something like |\ytableau@box{##}| because of the following complication:
+% 
+% When TeX sees |\ytableau@box{|, it absorbs tokens up until the next unmatched |}| without
+% interpreting them and then feeds that to the macro as |#1|.  Unfortunately, we would like it to
+% be possible to omit |\\| on the last line (as people are used to this, and Knuth provided for it
+% with |\crcr|).  But since |ytableau| is an environment, the ending of |\halign| is hidden in the
+% macro |\endytableau| (or |\end{ytableau}|) which is \emph{not expanded by} |\halign| while
+% reading for |##| in the proposed code.
+% 
+% The workaround is to pretend that |##| is not an argument to a macro until we get deep inside
+% |\ytableau@startbox|, where (after some processing) it is fed to an |\hbox| inside math mode. 
+% |\hbox| is not really a macro (it's a builtin) and it does interpret its contents as it reads
+% them, and since we have finally set up the desired typesetting environment we can let it read
+% |##| properly.  Since we are \emph{still} inside an |\halign|, eventually it will expand
+% |\endytableau| and |##| will terminate properly.  Whew.
+%    \begin{macrocode}
+    \halign\bgroup&\ytableau@startbox{\ytableau@defarg}{#1}##%
+                                             \ytableau@endbox\cr%
+}
+{%
+%    \end{macrocode}
+% The |\crcr| supports the omission of |\\| in the last row.  That's a pretty modest goal for all
+% the work that went into thinking up this crazy scheme.
+% The following delimiters close, respectively, |\halign|, |\ytableau@centering|, |\hbox|, and the 
+% |{| which protects the |\halign| in case the tableau finds itself in another alignment.
+%    \begin{macrocode}
+    \crcr\egroup%
+   \egroup%
+  $\egroup%
+ \iffalse{\fi}%
+%    \end{macrocode}
+% Support for chaining.  We allow |\endytableau| to be followed by |*[...]{...}|, which is fed to
+% |\ydiagram| as-is.  This only works in the short forms |\ytableaushort| and |\ydiagram|, since in
+% |\end{ytableau}| there is extra code intervening before the following characters and no way to
+% insert things in it.
+%    \begin{macrocode}
+ \ifnum\wd\ytableau@thistableau>\wd\ytableau@tableaux%
+  \ytableau@tableauwd=\wd\ytableau@thistableau%
+ \else%
+  \ytableau@tableauwd=\wd\ytableau@tableaux%
+ \fi%
+%    \end{macrocode}
+% We have saved the larger width, but now |\ytableau@thistableau| must have width zero so that it
+% can be overlaid with the existing tableaux.
+%    \begin{macrocode}
+ \wd\ytableau@thistableau=0pt%
+ \setbox\ytableau@tableaux%
+  =\hbox{\box\ytableau@thistableau\unhbox\ytableau@tableaux}%
+%    \end{macrocode}
+% Now we set the width to what it should be.
+%    \begin{macrocode}
+ \wd\ytableau@tableaux=\ytableau@tableauwd%
+ \ytableau@ifstar%
+  {\ydiagram}%
+  {%

+%    \end{macrocode}
+% The other two alignments are straightforward, but to get |top| requires some work when we are
