+This package provides macros to collect and process an macro argument (i.e.
+something which looks like a macro argument) as horizontal box instead as a real
+macro argument. These "arguments" will be stored like when using \savebox,
+\sbox or the lrbox environment and allow verbatim or other special code. Instead
+of explicit braces also implicit braces in the form of \bgroup and \egroup
+are supported. This allows to split the begin and end over different macros or to
+place them in the begin and end code of an environment. The provided macros are
+mainly intended to be used inside other macros or environments

+% \begin{abstract}
+% This package provides macros to collect and process an macro argument (i.e.\ something which looks like a macro argument)
+% as horizontal box instead as a real macro argument.
+% These ``arguments'' will be stored like when using \Macro\savebox, \Macro\sbox or the \env{lrbox} environment
+% and allow verbatim or other special code.
+% Instead of explicit braces also implicit braces in the form of \Macro\bgroup
+% and \Macro\egroup are supported. This allows to split the begin and end over different macros or to place them
+% in the begin and end code of an environment.
+% The provided macros are mainly intended to be used inside other macros or environments.
+%
+% {\bfseries\color{red}Disclaimer: This is an beta release of this package and the code might still change in future releases.}
+% \end{abstract}
+%
+% \section{Quick overview}
+% The following macros are provided for users (document authors) and \LaTeX\ package authors/programmers and described in the following sections.
+% The \MacroArgs* and \MacroArgs[<\ldots>] arguments are as always optional. The \MacroArgs{<box content>} can also be written as 
+% \Macro\bgroup<box content>\AlsoMacro\egroup and be split across macro boundaries.
+%

+%
+% \section{Dependencies, Compatibility and Installation}
+% This package does not depend on any other \LaTeX\ package or class.
+% It should be compatible with all versions of \LaTeX (DVI-\LaTeX, pdf\LaTeX, Xe\LaTeX\ and Lua\LaTeX).
+% Colored content will be correctly handled.
+%
+% This package should be (soon) part of the standard distributions TeXLive and MikTeX and can be installed over the 
+% provided package manager (i.e.\ TeXLive: |tlmgr install collectcell|).
+% This package can be also manually unpacked from |collectbox.dtx| by compiling the file |collectbox.ins| with \LaTeX\ or \TeX.
+% This documentation can be created by compiling |collectbox.dtx| using pdf\LaTeX\ in DVI or PDF mode.
+% The unpackaged package file |collectbox.sty| should be copied to a newly created directory |$TEXMF/tex/latex/collectbox/| under Linux
+% or |%TEXMF%\tex\latex\collectbox\| under MS Windows where |$TEXMF| and |%TEXMF%| represents the local \TeX\ tree.
+% The documentation and README file can be copied to |$TEXMF/doc/latex/collectbox/|.
+% Some \TeX\ distributions require to update the list of files in the \TeX\ tree, e.g.\ by running |texmf $TEXMF| afterwards.
+% MikTeX users can use the graphical interface of the package manager.
+%
+%
+% \section{User Interface}
+% The following macros are provided on the user level.
+%
+% \subsection{Macros to collect boxes}
+% \DescribeMacro\collectbox{<code>}{<box content>}
+% \DescribeMacro\collectbox{<code>}\AlsoMacro\bgroup<box content>\AlsoMacro\egroup
+% In its basic form this macro is written as \Macro\collectbox{<code>} and collects the following `group' in explicit (|{ .. }|) or implicit (|\bgroup .. \egroup|) braces
+% as box (here represented as \MacroArgs{<box content>}). Afterwards the user provided \MacroArgs<code> is executed. This code is processed inside an internal group
+% and has access to the just collected content using \Macro\BOXCONTENT and other macros described further below. Usually the code does some calculations and/or modifications
+% on the collected box and then typesets it using \Macro\BOXCONTENT.
+%
+% An example is
+% \codeline{\Macro\collectbox{\AlsoMacro\fbox{\AlsoMacro\BOXCONTENT}}'{\verb+verbatim stuff \space\empty+}'}
+% which results in
+% \codeline{\collectbox{\fbox{\BOXCONTENT}}{\verb+verbatim stuff \space\empty+}}
+%
+% \DescribeMacro\collectbox*{<code>}{<box content>}
+% \DescribeMacro\collectbox*{<code>}\AlsoMacro\bgroup<box content>\AlsoMacro\egroup
+% Because very often the \Macro\BOXCONTENT is simply fed as argument to a macro at the end of the \MacroArgs<code> a star version exists which adds \MacroArgs{\AlsoMacro\BOXCONTENT} automatically 
+% to the end of the code.
+%
+% An above example can be therefore simplified as:
+% \codeline{\Macro\collectbox*{\AlsoMacro\fbox}'{\verb+verbatim stuff \space\empty+}'}
+% which results in:
+% \codeline{\collectbox*{\fbox}{\verb+verbatim stuff \space\empty+}}
+%
+% \noindent
+% Using this macro a \Macro\fbox variant can be defined which reads its content as real box and not as macro argument:
+% \codeline{\Macro\newcommand{\AlsoMacro\Fbox}{\AlsoMacro\collectbox*{\AlsoMacro\fbox}}}
+%
+% \DescribeMacro\collectbox [<code at begin>]{<code>}[<code at end>]{<box content>}
+% \DescribeMacro\collectbox [<code at begin>]{<code>}[<code at end>]\AlsoMacro\bgroup<box content>\AlsoMacro\egroup
+% \DescribeMacro\collectbox*[<code at begin>]{<code>}[<code at end>]{<box content>}
+% \DescribeMacro\collectbox*[<code at begin>]{<code>}[<code at end>]\AlsoMacro\bgroup<box content>\AlsoMacro\egroup
+% Finally two optional arguments exists which allow the placement of further code at the beginning and end of the collected box.
+% This code is part of the box and is expanded before the main \MacroArgs<code> which is expanded after the box is fully collected.
+% In other words \Macro\collectbox!\optionaloff! [<code at begin>]{<code>}[<code at end>]{<box content>} is basically the same as
+% \Macro\collectbox{<code>}{<code at begin><.><box content><.><code at end>}, with the difference that the first form allows an user defined macro
+% to set the begin and end code while the box content is provided by the user.
+% Note that there is also some internal code \meta{.} between \meta{code at begin} and \meta{box content} as well as between \meta{box content} and \meta{code at end}.
+%
+% \paragraph{Example:} \leavevmode\Macro\fbox like macro which reads its ``argument'' as box and sets it green first:
+% \begin{macroquote}
+%  \newcommand!\optionaloff!{\AlsoMacro\GFbox}{\AlsoMacro\collectbox*[\AlsoMacro\color{green}]{\AlsoMacro\fbox}}\\
+%  \GFbox{'test $a=4$ \verb|\relax|'}
+% \end{macroquote}
+% will result in:
+% {\newcommand{\GFbox}{\collectbox*[\color{green}]{\fbox}}%
+%  \GFbox{test $a=4$ \verb|\relax|}}
+%
+%
+% \DescribeMacro\collectedbox
+% This macro represents the box register defined by \Macro\newsavebox\relax which holds the collected box.
+% It can be used with the \LaTeX's macro \Macro\usebox{<box register>} or with plain\TeX\ 
+% macros like \Macro\box, \Macro\copy, \Macro\unhbox or \Macro\unhcopy.
+%
+% \DescribeMacro\BOXCONTENT
+% This macro is short for \Macro\usebox{\AlsoMacro\collectedbox} and will place the collected box into the document. It can be used multiple times inside \MacroArgs<code>.
+%
+% \DescribeMacro\width
+% \DescribeMacro\height
+% \DescribeMacro\depth
+% \DescribeMacro\totalheight
+% These macros represent the dimension of the collected box and can be used inside \MacroArgs<code>\relax. Here \Macro\height is the height of the box above the baseline
+% and \Macro\depth the lengths how far the box is going below the baseline. Both values added together are provides as \Macro\totalheight.
+% The box width is given by \Macro\width.
+%
+%
+% \DescribeMacro\collectboxto{<box register>}[<code at begin>]{<code>}[<code at end>]{<box content>}
+% \DescribeMacro\collectboxto{<box register>}[<code at begin>]{<code>}[<code at end>]\AlsoMacro\bgroup<box content>\AlsoMacro\egroup
+% This macro collects its last ``argument'' as horizontal box and stores into into the user provided \meta{box register}.
+% The \meta{code at begin} and \meta{code at end} are executed at begin and end of the \meta{box content} as part of the box.
+% Afterwards the user provided \meta{code} is executed. In contrast to \Macro\collectbox no group is added for both the box register assignment or the code
+% and also none of the above auxiliary macros for the box dimensions and content can be used. The collected box can be typeset using \Macro\usebox{<box register>}
+% and its width, height and depth dimensions can be accessed using the \TeX\ primitives \Macro\wd<box register>, \Macro\ht<box register>, \Macro\dp<box register>.
+%
+% Appropriate grouping must be added manually if the overall code should be kept local. Proper places to open and close the group is somewhere before 
+% the \Macro\collectboxto macro and in the \meta{code} after the box was used, respectively.
+% The box register must be declared beforehand using \Macro\newsavebox\relax (\LaTeX) or \Macro\newbox (\TeX).
+% The provided box register \Macro\collectedbox can be used here but will be overwritten by further usages of most of the macros of this package.
+% The \LaTeX\ code also provides \Macro\@tempboxa for temporary usages.
+%
+% This macro can be used to create macros which collect more than one argument as box. For this two box registers are required and the \meta{code} of the 
+% first \Macro\collectboxto usage must call it second time. The second \meta{code} then typesets the two boxes.
+%
+% \subsection{Support for environments}
+%
+% \DescribeMacro\collectboxcheckenv{<name>}
+% This macro allows macros which use \Macro\collectbox to also be used as an environment.
+% For this \Macro\collectboxcheckenv must be used before \Macro\collectbox with the macro name as argument.
+% It then detects if the macro is used by itself or is called by \Macro\begin{<name>} and adjusts the internal configuration
+% accordantly. In macro-mode it does not change anything, but in environment-mode a \Macro\begingroup is used to keep the configuration changes local.
+% The corresponding \Macro\end<name> macro need to close then both the box group using \Macro\egroup and then close the outer group \Macro\engroup.
+% A suitable version is automatically defined if this macro doesn't exists yet.
+% In environment-mode starting and trailing spaces are ignored which is also the normal behaviour of similar environments like \env{minipage}.
+%
+% \paragraph{Example:} Defines \Macro\foobar macro which can also be used as \env{foobar} environment.
+% \begin{codequote}
+%     \AlsoMacro\newcommand'*'{\Macro\foobar}'{%'\\
+%     !\mbox{}!~~~~\AlsoMacro\collectboxcheckenv{foobar}'%'\\
+%     !\mbox{}!~~~~\AlsoMacro\collectbox'*'{\Macro\fbox}'%'\\
+%     '}'%
+% \end{codequote}
+%
+%
+% \section{Programmers Interface}
+%
+% For the package author/programmer and more advanced users the following internal macros are provided.
+% If used inside a document file they must be wrapped inside \Macro\makeatletter and \Macro\makeatother\relax (outside the macro which uses them).
+%
+% \DescribeMacro\collectbox@{<code at begin>}{<code>}{<code at end>}{<box content>}
+% This macro is the internal form of \Macro\collectbox with the optional arguments replaced by mandatory ones.
+% The \Macro\collectbox macro itself uses it after checking for and reading the optional arguments.
+% If this macro is to be used in other macros this overhead can be avoided by using the internal form directly.
+% Not used optional arguments can be simply kept empty. The star version is not supported but can be easily substituted by 
+% manually placing the \MacroArgs{\Macro\BOXCONTENT} at the end of \MacroArgs<code>.
+%
+% The above example can therefore be written in the faster processed form:
+% \begin{macroquote}
+%  \makeatletter\\
+%  \newcommand!\optionaloff!{\AlsoMacro\GFbox}{\AlsoMacro\collectbox@{\AlsoMacro\color{green}}{\AlsoMacro\fbox}{}}\\
+%  \makeatother\\
+%  \GFbox{test $a=4$ \verb|\relax|}%
+% \end{macroquote}
+% which results in:
+% {\makeatletter
+%  \newcommand{\GFbox}{\collectbox@{\color{green}}{\fbox{\BOXCONTENT}}{}}%
+%  \makeatother
+%  \tracingall
+%  \GFbox{test $a=4$ \verb|\relax|}%
+% }
+%
+%
+% \DescribeMacro\@collectbox{<code>}{<box content>}
+% This macro is a short version of \Macro\collectbox and only accepts one argument \MacroArgs<code> besides the later \meta{box content}.
+% It is intended for quick version for macros which do not need to insert code at begin or after the box content.
+%
+% \DescribeMacro\collectboxto@{<code at begin>}{<code>}{<code at end>}{<box content>}
+% This macro is the internal form of \Macro\collectboxto with the optional arguments replaced by mandatory ones.
+% The \Macro\collectboxto macro itself uses it after checking for and reading the optional arguments.
+% If this macro is to be used in other macros this overhead can be avoided by using the internal form directly.
+% Not used optional arguments can be simply kept empty.
+%
+% \DescribeMacro\@collectboxto{<box register>}{<code>}{<box content>}
+% This macro is a short version of \Macro\collectboxto and only accepts one \meta{code} argument.
+% It is intended for quick version for macros which do not need to insert code at begin or after the box content.
+%
+% \DescribeMacro\nocollectbox@{<code at begin>}{<code>}{<code at end>}
+% Turns a following brace group into basically \Macro\hbox{<code at begin><content><code at end>}<code>.
+% This is useful if a box needs to be build like that but no actual processing of the content is required, e.g.\ for horizontal alignment only.
+% Note that there are some internal code between the three code arguments.
