+% \begin{abstract}
+% This article documents a \LaTeX\ package, `rotating.sty',
+% which performs most sorts of
+% rotation one might like, including rotation of complete floating
+% figures and tables.
+% \end{abstract}
+%
+% \section{Introduction}
+%
+% The package provides:
+% \begin{itemize}
+% \item two new environments, \texttt{sidewaystable} and
+%   \texttt{sidewaysfigure}, each of which produces a single page-size
+%   float with contents rotated $\pm90$\,degrees; and
+% \item a variety of other rotation-related commands and environments.
+% \end{itemize}
+%
+% Note that the package uses rotation facilities from the
+% \textsf{graphicx} package.  When generating DVI output, users should
+% note that rotation is typically \emph{not} visible in a DVI viewer:
+% conversion to, and viewing, PostScript or PDF is necessary.
+%
+% \section{Usage} 
+%
+% \subsection{Package options}
+%
+% Sideways figures and tables always take up the whole page. In
+% single-sided documents, they may be rotated so that the bottom of
+% the figures is on the left (package option
+% `\texttt{counterclockwise}') or the right (package option
+% `\texttt{clockwise}').  The default is to turn so that the bottom is
+% on the right (option `\texttt{clockwise}').
+%
+% Option `\texttt{anticlockwise}' is an alias for
+% `\texttt{counterclockwise}'.
+%
+% If the `\texttt{twoside}' option has been given to the main document
+% class (either explicitly, or implicitly as in the default for book
+% class), the package will rotate sideways figures according to the
+% page number (this requires at least two passes through \LaTeX{}).
+% If you want the `\texttt{twoside}' option, but want the figures
+% always in one direction, use the `\texttt{figuresright}' or
+% `\texttt{figuresleft}' options to the package.
+%
+% The package can produce a lot of logging information; the
+% amount of information is controlled by the package options
+% `\texttt{quiet}' (fewest messages; default), `\texttt{log}' and
+% `\texttt{chatter}' (most messages).
+%
+% All other options are passed to the \textsf{graphicx} package when
+% it is loaded to provide rotation functions.
+%
+% \subsection{Float environments}
+%
+% The environments \texttt{sidewaystable} and \texttt{sidewaysfigure}
+% introduce landscape-form floating tables and figures, respectively.
+% (Each of the environments has a ``starred'' version, such as
+% \texttt{sidewaystable*}, for a single-column float in a double-column
+% area of the document.)
+%
+% New rotated environments may be declared using the combined
+% facilities of the float and rotfloat packages. 
+%
+% \subsection{Other environments and commands}
+% The package provides other \LaTeX\ environments:
+% \begin{description}
+% \item[\mdseries\ttfamily sideways] prints the contents of the
+%   environment turned through 90 degrees counterclockwise;
+% \item[\mdseries\ttfamily turn] prints the contents turned through an
+%   arbitrary angle (the argument to the environment);
+% \item[\mdseries\ttfamily rotate] prints the contents turned through
+%   an arbitrary angle but does \emph{not} leave any space for the result
+% \end{description}
+%
+% The command \cs{turnbox}\marg{angle}\marg{matter to turn} is a macro
+% version of the \texttt{rotate} environment.
+%
+% A set of examples is given in the file \texttt{examples.tex}
+%
+% \subsection{Positioning}
+%
+% Floats appear one to a page, and are positioned by spacer skips that
+% appear (logically) above and below the floating object.  The skips,
+% \cs{rotFPtop} and \cs{rotFPbot}, are initialised from the standard
+% \LaTeX{} (internal) \cs{@fptop} and \cs{@fpbot} skips.  As a result,
+% by default, rotated floats appear horizontally centred on their
+% float pages.
+%
+% Some sensible values for the registers are:
+% \par\noindent
+% \begin{tabular}{@{}llp{3in}@{}}
+%   \cs{rotFPtop} & \cs{rotFPbot} & Effect \\
+%   \hline
+%   0pt plus 1fil & 0pt plus 1fil & figure/table appears in middle 
+%                                   (default value)               \\
+%   0pt           & 0pt plus 1fil & figure/table appears with its top
+%                                   nearest the edge of the page   \\
+%   0pt plus 1fil & 0pt plus 2fil & figure/table's bottom appears
+%                                   twice as far from the edge as the
+%                                   top does
+% \end{tabular}
+%

+% \section{Sideways figures and tables}
+% Now for the macros to provide a complete
+% environment for sideways figures and tables.
+% We define two environments |sidewaysfigure| and 
+% |sidewaystable| that
+% fit in with the normal table and figure floats. These are `fixed'
+% environments that  just do 90 degree rotation, but it would be easy
+% to parameterize this to do other rotations if needed (the mind
+% boggles\ldots)
+% 
+% \begin{macro}{\@rotfloat}
+% \begin{macro}{\@xrotfloat}
+% \begin{macro}{\rot@float@box}
+% First a generalised `rotfloat' environment. We need to intercept
+% \LaTeX's float macros, in order to change the assumed width of a
+% float being |\columnwidth|. We want it to work on a width of
+% |\textheight| so that when we rotate the float, it comes out
+% the right height. This is not actually very satisfactory, since what

+% it has not happened yet. The result of these difficulties is that
+% rotated figures  always end up as full page figures.

+% code.

+% \section{History}
+%
+% Version 2.0 is a complete re-write, with most of the work now
+% being done by the \LaTeXe\ graphics package.
+%
+% Version 2.1 provides a `clockwise' option to reinstate the behaviour
+% described in the `\LaTeX\ Companion'
+%
+% Version 2.2 just intercepts the standard float macros instead
+% of copying and changing the. The `twoside' option is obeyed.
+%
+% Version 2.5 corrects problems in sideways figures.
+%
+% Version 2.6 is a rewrite of the sideways floats via Frank Mittelbach
+% (to whom many thanks for looking at the  mangy code).
+%
+% Version 2.7 is checked for \LaTeX\ of December 94, and adds the option
+% of twoside behaviour independent of the general twoside.
+%
+% Version 2.8 cleans up some mistakes pointed out by Harald Axel
+% Sommerfeldt.
+%
+% Version 2.9 cleans up some (more) mistakes pointed out by Harald
+% Axel Sommerfeldt.
+%
+% Version 2.13a permits positioning of rotated floats in the same way
+% as they are positioned in `normal' floats.
+%
+% Version 2.14 is the first to be published anywhere as the outcome of
+% maintenance by Robin Fairbairns.
+%
+% Version 2.15 deals with page-numbering bug for auto-float-rotation,
+% and tidying of messages; published to ctan
+%
+% Version 2.16 uses colour boxes as necessary; published to ctan.
+% Version 2.16a provides the colour box commands \cs{AtBeginDocument}.
