+
+The package provides
+
+ - `\grabbox<*>{<register>}[<pre>]{<mode>}[<post>]{<next>}`: grab the
+ next argument as a box in `<mode>` (`\hbox`, `\vbox` or `\vtop`) and save it
+ in box `<register>`. After the box is saved execute `<next>`. Inside of the
+ box one can inject `<pre>` before the contents and `<post>` after them. If
+ the star is not given spaces are stripped from the start and the end of the
+ box.

+%
+% \section{Introduction}
+%
+% Sometimes I happen to write macros and environments which don't care for the
+% exact contents of an argument but only for that contents typeset
+% representation and its dimensions. In that case I personally dislike the fact
+% that those arguments couldn't contain verbatim material if coded straight
+% forward. Thus the macros distributed hereby came into existence.
+%
+% This package provides \cs{grabbox} to grab an argument inside of a box. The
+% used mechanism allows category code changes in that argument as long as it is
+% used in a place allowing category code changes (so not inside of another
+% argument).
+%
+% It is written as a docstrip file: executing |latex grabbox.dtx| generates the
+% \file{grabbox.sty} file and typesets this documentation; execute
+% |tex grabbox.dtx| to only generate \file{grabbox.sty}.
+%
+% \section{Acknowledgement}
+%
+% I want to thank Enrico Gregorio for helping me develop first versions of the
+% used mechanisms for the second iteration of my \pkg{ducksay} package. If he
+% hadn't helped me back then, I wouldn't have considered the used method
+% further -- because the user interface would've been too clumsy and require
+% strange markup like |\foo arg}| -- and therefore this package wouldn't have
+% been created.
+%
+% \section{The macro}
+%
+% \begin{function}{\grabbox}
+% \begin{syntax}
+% \cs{grabbox}\meta{*}\marg{box register}\ignorespaces^^A
+% \oarg{inject pre}\marg{box type}\oarg{inject post}\ignorespaces^^A
+% \marg{afterwards}
+% \end{syntax}
+% grabs the next braced argument and stores it inside of the box \meta{box
+% register}. The box is of \meta{box type}, which should be one of \cs{hbox}
+% or \cs{vbox} or \cs{vtop}. \meta{inject pre} will be injected at the
+% beginning of the box and can affect its contents, \meta{inject post} will be
+% injected after the box but can't be affected by stuff inside of \meta{inject
+% pre}. Unless the \meta{*} is given leading and trailing spaces will be
+% stripped from the box. After the box is read in \meta{afterwards} will be
+% inserted.
+% \end{function}
+%
+% \smallskip
+% All assignments are made local. Currently it is not safe to nest macros
+% which use \cs{grabbox}. It should become safe if your macros use
+% \cs{grabbox} inside of a group, so the inner \cs{grabbox} doesn't affect the
+% outer one.
+%
+% \cs{grabbox} uses \cs{afterassignment} and \cs{aftergroup} to do its magic.
+% The former should be safe where it is used, the latter is used inside of the
+% boxed argument before any contents are inserted.
+%
+% Since \cs{grabbox} works by setting a boxregister using \cs{setbox} (and a
+% bunch of temporary macros), it is of course not expandable and defined
+% \cs{protected}. Bear in mind that macros created with \cs{grabbox} are
+% not expandable.
+%
+% \section{Useless Example!}
+%
+% First we need to reserve us a box register for this example:
+% \begin{verbatim}
+% \newsavebox\ourbox
+% \end{verbatim}
+% Next we define a macro which takes some arguments and uses \cs{grabbox}:
+% \begin{verbatim}
+% \newcommand\examplecmd[2]
+% {%
+% \begingroup
+% \grabbox\ourbox[\itshape]\hbox[ \sffamily is]{\examplecmdOut{#1}{#2}}
+% }
+% \end{verbatim}
+% And we need our helper macro which is executed after \cs{grabbox}:
+% \begin{verbatim}
+% \newcommand\examplecmdOut[3]
+% {%
+% \begin{tabular}[t]{@{}ll@{}}
+% Arg1: & #1\\
+% Arg2: & #2\\
+% Box: & \unhbox\ourbox\\
+% Arg3: & #3
+% \end{tabular}%
+% \endgroup
+% }
+% \end{verbatim}
+%
+% The result is a macro that takes two ordinary arguments, after those a
+% box in horizontal mode and finally another ordinary argument. If we use this
+% macro we get the following:
+% \begin{center}
+% \newsavebox\ourbox
+% \newcommand\examplecmd[2]
+% {%
+% \begingroup
+% \grabbox\ourbox[\itshape]\hbox[ \sffamily is]{\examplecmdOut{#1}{#2}}
+% }%
+% \newcommand\examplecmdOut[3]
+% {%
+% \begin{tabular}[t]{@{}ll@{}}
+% Arg1: & #1\\
+% Arg2: & #2\\
+% Box: & \unhbox\ourbox\\
+% Arg3: & #3
+% \end{tabular}%
+% \endgroup
+% }%
+% \examplecmd{Hi,}{my}{\verb|name|}{Steve!}
+% \end{center}
+% One can see that \verb|\sffamily is| of \meta{inject post} is not affected by
+% the |\itshape| in \meta{inject pre}. The used code to generate that table was:
+%
+% \begin{verbatim}
+% \examplecmd{Hi,}{my}{\verb|name|}{Steve!}
+% \end{verbatim}
+%
+% \section{Useful Example?}
+%
+% This example provides a macro which typesets its mandatory argument in a block
+% of a definable number of lines, it is meant for a single paragraph.
+%
+% \begin{verbatim}
+% % Getting a box register:
+% \newsavebox\RectangleBox
+% % Defining the main macro:
+% \newcommand\Rectangle[1][4]
+% {%
+% \begingroup
+% \grabbox\RectangleBox\hbox
+% {%
+% % Since we don't want to read more arguments after the box,
+% % we don't need a second macro and can put the output routine
+% % here.
+% \begin{minipage}{\dimexpr\wd\RectangleBox/#1\relax}
+% \parfillskip0pt
+% \unhbox\RectangleBox
+% \end{minipage}%
+% \endgroup
+% }%
+% }
+% \end{verbatim}
+%
+% As you can see, this macro uses \cs{grabbox} in a group delimited by
+% \cs{begingroup} and \cs{endgroup}. It should therefore be safe to nest it
+% inside other macros using \cs{grabbox}.
+%
+% Finally a usage example of our new macro (with the \pkg{duckuments} package
+% loaded):
+%
+% \begin{verbatim}
+% \begin{center}
+% \Rectangle[9]{\blindduck}
+% \end{center}
+% \end{verbatim}
+% Results in:
+% \begin{center}
+% \newsavebox\RectangleBox
+% \newcommand\Rectangle[1][4]
+% {%
+% \begingroup
+% \grabbox\RectangleBox\hbox
+% {%
+% \begin{minipage}{\dimexpr\wd\RectangleBox/#1\relax}
+% \parfillskip0pt
+% \unhbox\RectangleBox
+% \end{minipage}%
+% \endgroup
+% }%
+% }
+% \Rectangle[9]{\blindduck}
+% \end{center}
