Description
-----------
LaTeX users sometimes need to ensure that two or more blocks of text
-occupy the same amount of horizontal space on the page. To that end,
-the eqparbox package defines a new command, \eqparbox, which works
-just like \parbox, except that instead of specifying a width, one
-specifies a tag. All eqparboxes with the same tag -- regardless of
-where they are in the document -- will stretch to fit the widest
-eqparbox with 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 documentation.

% \section{Usage}
%
-% \DescribeMacro{\eqparbox}
-% The primary macro in the \textsf{eqparbox} package is |\eqparbox|.
-% Usage is almost identical to that of |\parbox|:
-%
-% \begin{center}
-% |\eqparbox| \oarg{pos} \oarg{height} \oarg{inner-pos}
-% \marg{tag} \marg{text}
-% \end{center}
-%
-% \noindent
-% The only difference is that, where |\parbox| has its \meta{width}
-% argument, |\eqparbox| has \meta{tag}. (For a description of the
-% remaining arguments, look up |\parbox| in any \LaTeXe\ book or in
-% the \texttt{usrguide.tex} file that comes with \LaTeXe.) \meta{tag}
-% can be any valid identifier. All |\eqparbox|es with the same tag
-% will be typeset in a box wide enough to hold the widest of them.
+% \begin{decl}
+% |\eqparbox| \oarg{pos} \oarg{height} \oarg{inner-pos} \marg{tag} \marg{text} \\
+% |\eqmakebox| \oarg{tag} \oarg{pos} \marg{text} \\
+% |\eqframebox| \oarg{tag} \oarg{pos} \marg{text} \\
+% |\eqsavebox| \marg{cmd} \oarg{tag} \oarg{pos} \marg{text}
+% \end{decl}
+%
+% These macros are almost identical to |\parbox|, |\makebox|,
+% |\framebox|, and |\savebox|, respectively. The key difference is
+% that the \meta{width} argument is replaced by a \meta{tag} argument.
+% (For a description of the remaining arguments, look up |\parbox|,
+% |\makebox|, |\framebox|, and |\savebox| in any \LaTeXe\ book or in the
+% \texttt{usrguide.pdf} file that comes with all \TeX\ distributions.)
+% \meta{tag} can be any valid identifier. All boxes produced using the
+% same tag are typeset in a box wide enough to hold the widest of them.
% Discounting \TeX's limitations, any number of tags can be used in the

+% One solution is to use \pkgname{eqparbox}'s |\eqmakebox| macro. Like
+% |\makebox|, |\eqmakebox| supports the ``|s|'' (stretch) value for the
+% \meta{pos} argument, which causes the \meta{text} argument to stretch
+% to the width of the box. However, while |\makebox| requires the width
+% to be specified explicitly, |\eqmakebox| automatically sizes all boxes
+% that use the same tag (in this case, each line of the input paragraph)
+% to the widest text's natural width. Here's how to use the
+% \pkgname{array} package's |\newcolumntype| macro to define a new
+% |tabular| column type, ``|S|'', that stretches whitespace as needed to
+% fit the widest line in the column:
+%
+% \begin{verbatim}
+% \newsavebox{\tstretchbox}
+% \newcolumntype{S}[1]{%
+% >{\begin{lrbox}{\tstretchbox}}%
+% l%
+% <{\end{lrbox}%
+% \eqmakebox[#1][s]{\unhcopy\tstretchbox}}}
+% \end{verbatim}
+%
+% \noindent
+% That code works by storing the current cell's contents within a box
+% called |\tstretchbox| then passing |\tstretchbox|'s contents to
+% |\eqmakebox|. (The |tabular| environment does not enable a cell's
+% contents to be passed directly to a macro, hence the |lrbox|
+% trickery.) Note that the ``|S|'' column type takes an argument, which
+% is the tag to pass to |\eqmakebox|. Using the preceding definition we
+% can typeset Figure~\ref{fig:line-by-line} as follows. To simulate
+% scanned handwriting in the left column we use the Calligra handwriting
+% font provided by the \pkgname{calligra} package.
