+% \begin{abstract}
+% Provides variants of common ``box''-macros which reads their content as real box and not as macro argument.
+% \end{abstract}
+%
+% \section{Introduction}
+% The \LaTeX\ core and several packages like \pkg{graphics/x} provide
+% some \cs{<xxx>box} macros which modify their content by first placing it into a box.
+% However, these macros still read their content as a macro argument and therefore
+% do no support verbatim content. This package provides variants of these macros
+% which use the authors other package \pkg{collectbox} to collect the content
+% as real box before it is modified (framed, raised, scaled, rotated, etc.).
+% This allows for verbatim and other special content.
+%
+% The provided macros simply have the same names as the original versions but
+% start with an upper-case letter instead.
+% However, these macros do not support the special \env{picture} syntax as the original macros.
+% The ``long-form'' macros, like \Macro\Makebox, can also be used as environments, but
+% not the ``short-form'' macros, like \Macro\Mbox. However, normally the long form uses
+% the short form anyway when no optional arguments are used.
+%
+% \subsection*{Length values}
+% Some of the macros await length values to specify a dimension of the content.
+% For all macros the lengths \Macro\width, \Macro\height, \Macro\depth and \Macro\totalheight\relax
+% (= height + depth) can be used to refer to the original dimensions of the content.
+% Also the \pkg{adjcalc} package from the \pkg{adjustbox} bundle is used to allow for
+% mathematical expressions for these values. By default the $\epsilon$-\TeX\ primitive
+% \Macro\dimexpr is used which allows for |+|, |-|, |*| and |/| as well as grouping using |( )|.
+% If either $\epsilon$-\TeX\ or the \pkg{adjcalc} package is not available, than the \pkg{calc}
+% package is used by default. It is also possible to use the \pkg{pgfmath} framework of the 
+% \pkg{pgf} bundle.  To select a different math back-end simply load the \pkg{adjcalc} package
+% with one of the options `|etex|', `|calc|', `|pgfmath|' or `|none|' before the \pkg{realboxes} package.  See the
+% \pkg{adjustbox} manual for more information about \pkg{adjcalc}.
+%
+%
+% \section{Usage}
+% The following macros are provided dependent on the used package options.
+% The options state other packages which are loaded and variants of their box macros are provided.
+% See the package manual for more details about these macros.
+% If loaded without any options the \opt{core} macros are loaded as well as all
+% variant of macros for all already loaded packages (``auto-detection mode'').
+%
+%
+% \subsection{\LaTeX\ code macros (option \opt{core})}
+%
+% \DescribeMacro{\Mbox}{<content>}
+% This variant of \Macro\mbox is the only macro which doesn't use \Macro\collectbox
+% because of the simplicity of the original macro. \Macro\Mbox will use \Macro\hbox
+% directly to process the \marg{content} (and will expand it to search for the opening brace).
+% The special case when \marg{content} is a single token is handling by using \Macro\mbox instead.
+%
+%
+% \DescribeMacro{\Makebox}[<width>][<position>]{<content>}
+% Places the \meta{content} in a box of width \meta{width} (by default the native width) and horizontally aligns it
+% accordantly to \meta{position}. Valid values are |l| for left, |r| for right and |c| for center alignment (default).
+% If no optional arguments are used this macro equals to \Macro\Mbox.
+%
+%
+% \DescribeMacro{\Fbox}{<content>}
+% Draws a frame around \meta{content} with a line width of \Macro\fboxrule and a separation of \Macro\fboxsep.
+% The baseline of the content is not affected.
+%
+%
+% \DescribeMacro{\Framebox}[<width>][<position>]{<content>}
+% Like \Macro\Makebox but draws a frame like \Macro\Fbox.
+% If no optional arguments are used this macro equals to \Macro\Fbox.
+%
+% \DescribeMacro{\Frame}{<content>}
+% Similar to \Macro\Fbox but does draw the frame tightly around its content with no separation. The resulting box will also have no depth, i.e.
+% might be moved up. Note that the original \Macro\frame macro is indented for use inside a \env{picture} environment but can also be used in
+% normal text. The line width is the current \env{picture} line width (|\@wholewidth|) which can be (globally) set 
+% using \Macro\linethickness{<length>} (also in normal text mode). 
+%
+%
+%
+%
+% \DescribeMacro{\Raisebox}{<length>}[<height>][<depth>]{<content>}
+% Raises the \meta{content} by \meta{length}. Negative values lower the content.
+% In addition to this the official height and depth can be set. This does not scale the content,
+% but only make \TeX\ reserve less vertical space.
+%
+%
+% \DescribeMacro{\Centerline}{<content>}
+% Places \meta{content} into a box of width \Macro\linewidth and centers it inside this box (even if the content is wider).
+% This is similar to \Macro\Makebox[\AlsoMacro\linewidth][c]{<content>}.
+%
+%
+% \DescribeMacro{\Leftline}{<content>}
+% Places \meta{content} into a box of width \Macro\linewidth and left aligns it inside this box.
+% If the content is wider it will stick out on the right site.
+% This is similar to \Macro\Makebox[\AlsoMacro\linewidth][l]{<content>}.
+%
+%
+% \DescribeMacro{\Rightline}{<content>}
+% Places \meta{content} into a box of width \Macro\linewidth and right aligns it inside this box.
+% If the content is wider it will stick out on the left site.
+% This is similar to \Macro\Makebox[\AlsoMacro\linewidth][r]{<content>}.
+%
+%
+% \DescribeMacro{\Rlap}{<content>}
+% Places \meta{content} into a box of zero width so that it laps over to the right site. The following material to the right will be printed
+% on top of it.
+% This is similar to \Macro\Makebox['0pt'][l]{<content>}.
+%
+% \DescribeMacro{\Llap}{<content>}
+% Places \meta{content} into a box of zero width so that it laps over to the left site. The content will be printed on top of the
+% previous material on the left.
+% This is similar to \Macro\Makebox['0pt'][l]{<content>}.
+%
+%
+% \DescribeMacro{\Parbox}[<pos>][<height>][<inner-pos>]{<width>}{<content>}
+% Places the \meta{content} into a paragraph box of the given \meta{width}.
+% The optional \meta{pos} argument can be used to select the vertical alignment of the box towards the surrounding:
+% `|t|' align box to the top baseline, `|b|' align to the bottom
+% baseline or `|c|' vertically center the content.
+% In addition to this the \meta{height} and the \meta{inner pos}ition can be set as further optional arguments.
+% Valid values for \meta{inner-pos} are: `|t|' flush content to the top, `|b|' flush content to the bottom,
+% `|c|' center the content inside the box or `|s|' to stretch the material vertically across the box. This only works if the content contains
+% something vertically stretchable.
+%
+% This macro uses also \pkg{collectbox} but redefines an internal macro to collect a vertical box instead of the usual horizontal one.
+%
+%
+% \DescribeMacro{\Sbox}{<\textbackslash boxregister>}{<content>}
+% This saves the \meta{content} into the given \meta{\textbackslash boxregister}, which must be first allocated
+% using \Macro\newsavebox{<\textbackslash boxregister>}.
+%
+% \DescribeMacro{\Savebox}{<\textbackslash boxregister>}[<width>][<position>]{<content>}
+% Sets the \meta{content} in a box of the given width and alignment like \Macro\Makebox and stores it in \meta{\textbackslash boxregister}.
+% If no optional arguments are used this macro equals to \Macro\Sbox.
+%
+% \Needspace*{10\baselineskip}
+% \subsection{Color macros (option \opt{color} or \opt{xcolor})}
+% \DescribeMacro{\Colorbox}[<color model>]{<color>}{<content>}
+% Sets the \meta{content} into a box with the given background \meta{color}. If required the \meta{color model} can be specified.
+%
+% \DescribeMacro{\Fcolorbox}[<fc model>]{<frame color>}[<bg model>]{<background color>}{<content>}
+% Sets the \meta{content} into a box with the given \meta{background color} and draws a frame around it like \Macro\Fbox but with
+% a given \meta{frame color}.
+% If required the color \meta{model} can be specified. If only the frame color model is specified it will also be used for the background color.
+%
+%
+% \Needspace*{6\baselineskip}
+% \subsection{Graphic macros (option \opt{graphics} or \opt{graphicx})}
+% \DescribeMacro{\Rotatebox}[<options>]{<angle>}{<content>}
+% Rotates the \meta{content} by \meta{angle} which is be default in degrees anti-clockwise (360 = full circle).
+% As \meta{options} the following keys can be used:
+% \begin{description}\def\oitem#1#2{\item[{\normalfont\ttfamily \MacroArgs'#1='<#2>\relax}]}%
+%  \oitem{x}{dimen}
+%  \oitem{y}{dimen}  Allows to specify the X and Y coordinate of the coordinate of the center of rotation relative to the reference point
+%                    of the box.
+%  \oitem{origin}{label} Allows to specify the center of the rotation using the following letters which can be combined: `|l|' left side,
+%       `|r|' right side, `|c|' center of the box, `|t|' top of the box, `|b|' bottom of the box and `|B|' for the base line.
+%       For example `|tr|' rotates about the top right corner.
+%  \oitem{units}{number} allows to change the default units of degrees anti-clockwise (|360|) to any \meta{number} of units in one full
+%       anti-clockwise rotation. For example |-360| specifies degrees clockwise and |6.283185| specifies radians.
+% \end{description}
+%
+%
+% \DescribeMacro{\Scalebox}{<h-scale>}[<v-scale>]{<content>}
+% Scales the \meta{content} by the given \meta{scale} factor. The vertical scaling can be specified independently using the optional argument.
+%
+%
+% \DescribeMacro{\Reflectbox}{<content>}
+% This reflects the \meta{content} and is equal to \Macro\Scalebox{-1}{1}{<content>}.
+%
+%
+% \DescribeMacro{\Resizebox}{<width>}{<height>}{<content>}
+% Resizes the \meta{content} to the given \meta{width} and/or \meta{height}.
+% The special value `|!|' can be used for one of the two values to scale it accordantly to the other value.
+% \Macro\Resizebox{'!'}{'!'}{<content>} will not change the size of the content.
+% If both values are used the aspect ratio might be changed. This can be avoided (for the local \TeX\ group) using
+% \Macro\setkeys{Gin}{keepaspectratio}. Then the content is scaled to the smaller of the two values.
+%
+% \DescribeMacro{\Resizebox}'*'{<width>}{<totalheight>}{<content>}
+% Like \Macro\Resizebox but scales the total height (= height + depth) instead of the height.
+%
+%
+% \subsection{Macros of the \pkg{dashbox} package (option \opt{dashbox})}
+%
+% \DescribeMacro{\Dbox}{<content>}
+% Like \Macro\Fbox but uses a dashed line instead.
+%
+% \DescribeMacro{\Dashbox}[<width>][<position>]{<content>}
+% Like \Macro\Framebox but uses a dashed line instead.
+%
+% \DescribeMacro{\Lbox}[<layers>]{<content>}
+% Draws some solid background layers to the lower right of the content which produces a shadow effect.
+% The \meta{content} is supposed to also use \Macro\Dbox or \Macro\Fbox to draw the foreground dash or frame box.
+% By default two layers are drawn but this can be changed by the optional argument.
+%
+% \DescribeMacro{\Dlbox}[<layers>]{<content>}
+% Like \Macro\Lbox but draws the layers with dashed lines instead.
+%
+%
+% \subsection{Compatibility with the \pkg{fancybox} package (option \opt{fancybox})}
+% The \pkg{fancybox} package defines its macros already in a verbatim compatible way.
+% However, if this option is used the \Macro\Sbox macro provided by the \opt{core} option is defined in a way to not 
+% collide with the \opt{Sbox} environment of this package.
