+% \section{Introduction}
+%
+% This document provides the commented source for \LaTeX{}
+% package files designed for the typesetting of
+% documents according to the rules for ISO international standards.
+% A seperate document provides the user manual~\cite{PRW96i}.
+% This manual is typeset according to the conventions of the
+% \LaTeX{} \textsc{docstrip} utility which enables the automatic
+% extraction of the \LaTeX{} macro source files~\cite{GOOSSENS94}.
+%
+% ISO (the International Organization for Standardisation) specify
+% their document layout requirements in ISO Directives~\cite{ISOD397}.
+% Unfortunately these Directives do not completely define the document
+% layout, leaving several aspects open to interpretation by the
+% document editor and re-interpretation by the ISO editorial board.
+% The following specifications are a re-implementation of the \LaTeX{}
+% macros that have been used for the production of camera ready copy
+% for the ISO~10303 standard {\em Product data representation and
+% exchange}. The initial release of ISO~10303:1994 consisted of twelve
+% parts and over 2400 pages. The editorial board of the ISO Central
+% Secretariat in Geneva accepted the typographic conventions embodied
+% in these macros.
+%
+% This manual is provided as a service for future developers
+% and maintainers of the
+% class and packages for ISO standards. It is assumed that any
+% any such person is \LaTeX{} literate and accustomed to supporting
+% complex class and package files~\cite{GOOSSENS94}.
+%
+%
+% Section~\ref{sec:docstrip} describes some
+% administrative elements and code for general use later in the specification.
+% Section~\ref{sec:rot} specifies
+% the macros for rotation of textual and tabular elements.
+%
+% \section{The {\sc docstrip} modules} \label{sec:docstrip}
+%
+% The following modules are used in the implementation to direct
+% {\sc docstrip} in generating the external files:
+% \begin{center}
+% \begin{tabular}{ll}
+% rot & produce the isorot package\\
+% rotne & produce the isorotne style file\\
+% driver & produce a documentation driver file \\
+% \end{tabular}
+% \end{center}
+%
+% \subsection{A driver for this document}
+%
+% The next series of code contains the documentation driver file for
+% \LaTeX, i.e., the file that will produce the documentation you are
+% currently reading. This will be extracted from this file by the
+% {\sc docstrip} program.

+%
+% Announce the name, option files and version for \LaTeX 2e files:
+% \begin{macrocode}
+%<rot>\ProvidesPackage{isorot}[2000/02/15 v2.1 ISO rotation package]
+% \end{macrocode}
+%
+% These files are for use with \LaTeX\ v2.09 or a disadvantaged \LaTeX 2e
+% distribution.
+% \begin{macrocode}
+%<rotne>\typeout{isorotne.sty [1997/12/02 v2 LaTeX 2.09 ISO rotation package]}
+% \end{macrocode}
+%
+%
+% \section{The \file{isorot} package and \file{isorotne} style} \label{sec:rot}
+%
+% The \file{isorot} package provides a specialization of the \file{rotating}
+% package
+% for use within ISO standard documents. The principal modifications
+% relate to the table and figure environments. The original \file{rotating}
+% package was developed by
+% Sebastian Rahtz and Leonor Barroca\footnote{Sebastian Rahtz and Leonor
+% Barroca, {\em A style option for rotated objects in TeX,} TUGboat, 13, 2,
+% pp 156--180, July 1992.}.
+%
+% Apparently not all distributions of \LaTeX{} contain the necessary
+% packages for a simple implementation. The \file{isorotne} style provides
+% the same capabilities for these users.
+% This essentially replaces all \LaTeX 2e facilities from \file{rotating}
+% by generic ones, and includes the relevent package sources within the one
+% file.
+%
+% \changes{v11}{1997/09/30}{Added new dvi drivers to isrotne package}
+% \changes{v2}{1997/12/02}{Updated rotations to rotating v2.12}
+% \changes{v2.1}{2000/02/15}{Updated to latest ISO class, and generalised for any class}
+% \begin{macrocode}
+%<*rot|rotne>
+% \end{macrocode}
+%
+% The package takes one option which prints debugging information.
+%
+% \begin{macro}{\PWRFc@tracing}
+% A counter controlling debug printing.
+% \begin{macrocode}
+\newcount\PWRFc@tracing
+\DeclareOption{errorshow}{\PWRFc@tracing\z@}
+\DeclareOption{debugshow}{\PWRFc@tracing5\relax}
+\DeclareOption*{\PassOptionsToPackage{\CurrentOption}{graphics}}
+\ProcessOptions
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\PWRF@trace}
+% A macro that gets the trace message as its argument.
+% \begin{macrocode}
+\newcommand\PWRF@trace[2]{%
+ \ifnum\PWRFc@tracing>#1\relax
+ \GenericWarning
+ {(isorot)\@spaces\@spaces}
+ {Package isorot: #2}%
+ \fi
+}
+% \end{macrocode}
+% \end{macro}
+%
+% For the \file{isorot} package most of the work is done by the
+% \file{graphicx} package, so make sure it is loaded. Also, David
+% Carlisle's \file{lscape} package is required for landscaping some
+% pages or long wide tables.
+% \begin{macrocode}
+%<*rot>
+\NeedsTeXFormat{LaTeX2e}
+\RequirePackage{graphicx}
+\RequirePackage{lscape}
+%</rot>
+% \end{macrocode}
+%
+% For the disadvantaged user, the required basic facilities are
+% a portion of the \file{graphics} package, which in turn requires
+% the \file{trig} package. We also need the code from the
+% \file{lscape} package.
+%
+% \begin{macrocode}
+%<*rotne>
+% \end{macrocode}
+% Firstly, here is the code from the \file{trig} package.
+%
+% \subsection{Trigonometry functions}
+%
+% \emph{The following is the contents of the \file{trig} package written by
+% David Carlisle. The code and explanations are from \file{trig.dtx}
+% version 1.08, dated 1994/10/16. The original file should be consulted
+% for a full explanation.}
+%
+%
+% These macros implement the trigonometric functions, sin, cos and tan.
+% In each case two commands are defined. For instance the command
+% |\CalculateSin{33}| may be isued at some point, and then anywhere
+% later in the document, the command |\UseSin{33}| will return the
+% decimal expansion of $\sin(33^\circ)$.
+%
+% The arguments to these macros do not have to be whole numbers,
+% although in the case of whole numbers, \LaTeX\ or plain \TeX\ counters
+% may be used. In \TeX{}Book syntax, arguments must be of type:
+% \meta{optional signs}\meta{factor}
+%
+% Some other examples are:\\
+% |\CalculateSin{22.5}|, |\UseTan{\value{mycounter}}|,
+% |\UseCos{\count@}|.
+%
+% Note that unlike the psfig macros, these save all previously
+% computed values. This could easily be changed, but I thought that in
+% many applications one would want many instances of the
+% same value. (eg rotating all the headings of a table by the
+% \emph{same} amount).
+%
+% Some useful constants for converting between degrees and radians.
+% $$\frac{\pi}{180}\simeq\frac{355}{113\times180}=\frac{71}{4068}$$

+%

+% environment which prints the enclosed pages in landscape rather
+% than portrait. For 2.09 this package does not work, so we provide
+% for the functionality here. The following code is taken from
+% the \file{lscape} package.\footnote{Version 3.0, last revised
+% 1994/10/05.}

+% \subsection{Drivers}
+%
+% Rotation is not done within \TeX\ but by the device drivers via |\special|
+% commands appropriate for each driver.

+% \end{macrocode}
+%
+% Life is much more difficult for the \file{isorotne} style as we have to
+% include source (runnable under 2.09) that the \file{isorot} package
+% gets for free.
+%
+% \begin{macro}{\Grot@start}
+% \begin{macro}{\Grot@end}
+% The commands |\Grot@start| and |\Grot@end| are defined which assume

+% \emph{Extension:} The following definitions implement some of
+% the ISO-specific stuff. They basically provide for the setting up of
+% the \file{lof} and \file{lot} files. |\rotcapfont| is the font for
+% typesetting any captions. For ISO it is bold and may be larger than normal.
