LaTeX users sometimes need to ensure that two or more blocks of text
-occupy the same horizontal space on the page. To that end, the eqparbox
-package defines \eqparbox, \eqmakebox, \eqframebox, and \eqsavebox
-commands, which work just like \parbox, \makebox, \framebox, and
-\savebox, respectively, except that instead of specifying a width, one
-specifies a tag. All boxes with the same tag -- regardless of where
-they are in the document -- will stretch to fit the widest box that uses
-that tag. This simple, equal-width mechanism can be used for a variety
-of alignment purposes, as is evidenced by the examples in eqparbox's

+% \subsection{Combining \texttt{l} and \texttt{p} column properties in a \texttt{tabular}}
+% \label{sec:tabular-l-p}
+%
+% In a |tabular| environment, |l|~columns, which automatically fit the
+% column to its contents, are good for short pieces of text. Long
+% pieces of text are best set within a |p|~column, which wraps text
+% within a specified width. But which column type should you use to
+% typeset text whose width is unknown (e.g.,~if the text is generated
+% programmatically)? With the help of \pkgname{eqparbox}'s
+% |\eqsetmaxwidth| macro (and the \pkgname{array} package's
+% |\newcolumntype| macro), it is possible to define a column type that
+% behaves like~|l| for short pieces of text and like~|p| for long pieces
+% of text:
+%
+% \begin{verbatim}
+% \newcolumntype{M}[1]{%
+% >{\begin{lrbox}{\csname#1box\endcsname}}%
+% l%
+% <{\end{lrbox}%
+% \eqparbox[t]{#1}{\unhcopy\csname#1box\endcsname\strut}}%
+% }
+% \end{verbatim}
+%
+% This can then be used as follows to produce the output shown in
+% Figure~\subref*{fig:maxwd-narrow}:
+%
+% \begin{verbatim}
+% \eqsetmaxwidth{maybebig}{0.5\linewidth}
+% \newsavebox{\maybebigbox}
+% \begin{tabular}{|M{maybebig}|l|}
+% \hline
+% Very short & Good \\
+% A little bit longer & Okay \\
+% \end{tabular}
+% \end{verbatim}
+%
+% \noindent
+% Because the text in the first column is narrower than half the line
+% width, the column behaves like an |l|~column. Now observe what
+% happens if we add a long piece of text to the column:
+%
+% \begin{verbatim}
+% \eqsetmaxwidth{maybebig}{0.5\linewidth}

-% Consequently, commands not valid within such a |tabular| (e.g.,~list

-% \item Evalaute \texttt{\string\eqparbox}'s \meta{text} argument

-% The following function does all the real work for the
-% \pkgname{eqparbox} package. It takes two parameters---\meta{tag} and
-% \meta{text}---and ensures that all boxes with the same tag will be as
-% wide as the widest box with that tag. It ends by passing \meta{tag}
-% and \meta{text} to the |\eqp@produce@box| command, which was defined
-% by the calling macro to produce a box using one of the existing
-% \LaTeXe\ commands.
-%
-% To keep track of box widths, |\eqp@compute@width| makes use of two global
-% variables for each tag: |\eqp@this@|\meta{tag} and
-% |\eqp@next|\meta{tag}. |\eqp@this@|\meta{tag} is the maximum width
-% ever seen for tag \meta{tag}, including in previous |latex| runs.
-% |\eqp@next@|\meta{tag} works the same way but is always initialized
-% to~|0.0pt|. It represents the maximum width to assume in
-% \emph{subsequent} |latex| runs. It is needed to detect whether the
-% dest text with tag \meta{tag} has been removed/shrunk. At the end of
