-% \section{Introduction}
-% \LaTeX{} document classes (templates) and packages (styles)
-% are traditionally distributed as pairs of
-% {\ttfamily{}.dtx} and{\ttfamily{}.ins} files,
-% written to the specifications and recommendations of the
-% \textsf{doc}, \textsf{ltxdoc}, and
-% \textsf{clsguide} packages.\par
-% \begin{itemize}
-% \item The {\ttfamily{}.dtx} (Doc\TeX{}) file is a 
-%     literate-programming document, containing modular code and
-%     annotations interleaved in such a way that each fragment
-%     of code and its explanation are adjacent;
-% \item The {\ttfamily{}.ins} file is an installer:
-%     when run through \LaTeX{}, it extracts the code from the
-%     {\ttfamily{}.dtx} file into the relevant class
-%     ({\ttfamily{}.cls}), package
-%     ({\ttfamily{}.sty}), and other files;
-% \item Running \LaTeX{} on the {\ttfamily{}.dtx} file
-%     itself extracts and typesets the documentation.
-% \end{itemize}
-% The construction of a {\ttfamily{}.dtx} document
-% is quite complex, with a special set of tags and conventions
-% to allow documentation to be separately identifiable to code.
-% The file format relies on the documentation being shielded by
-% a leading percent-space (\verb|%␣|) armour
-% on each line to prevent it being interpreted as part of the
-% code; and the environment tags surrounding the code itself
-% must be shielded by four such spaces
-% (\verb|%␣␣␣␣|). Apart from the
-% documentation, the treatment of the code and control
-% statements resembles more a data specification (which in some
-% ways it is) than a conventional text document.\par
-% XML, particularly in its traditional
-% `document' mode, as distinct from its
-% use as a data exchange format, offers many similar features to
-% \LaTeX{} (for example, the named identification of document
-% components), but with a rigid and invariable syntax that can
-% be checked programmatically by any validating XML processor.
-% By contrast, a \LaTeX{} document (and more specifically, a
-% {\ttfamily{}.dtx} document) can only be proved by
-% running it through \LaTeX{} itself: there is no equivalent to
-% the `pre-flight' type of standalone parsing or
-% validating available with XML.\par
-% The \emph{DocBook} vocabulary of XML
-% is designed for technical documentation in computing. It
-% provides markup both for textual documentation
-% \emph{and} for data-like structures that occur
-% in computer documentation, making it a viable candidate for
-% describing a literate-programming type of document such as
-% Doc\TeX{}.\par
-% The \emph{ClassPack} system is an
-% experiment in using \emph{DocBook} XML as
-% the storage format for \LaTeX{} class and package source code,
-% using the XLST2 language to transform the XML into pairs of
-% {\ttfamily{}.dtx} and {\ttfamily{}.ins} files.
-% There are a number of advantages to this approach:\par

+% \subsection*{v.1.19 (2020-05-19)}
 % \begin{itemize}
-% \item XML's syntax and document construction is extremely
-%     robust, and the design of the language means that an XML
-%     file can be machine-checked for errors of syntax and
-%     construction;
-% \item XML markup is traditionally self-descriptive, with
-%     element types being named according to what they are
-%     intended to contain. For example, a variable name can be
-%     marked up as
-%     \verb|<varname>foo</varname>|.\par
-% While it is perfectly possible to create a
-%     {\ttfamily{}\textbackslash{}varname} control sequence (macro) to do
-%     the same in \LaTeX{}, it is rarely done. Instead, authors
-%     have typically preferred to use visual formatting like
-%     \verb|\textit{foo}| for italics or
-%     \verb|\verb+foo+| for monospace type.
-%     This method means the variable reference is not
-%     immediately identifiable as containing a variable
-%     name~--- it could be anything;
-% \item Given suitably-descriptive markup, sharing document
-%     fragments between applications can be done
-%     programmatically, so a fragment implementing a \LaTeX{}
-%     feature (with its associated documentation) can be re-used
-%     in other class and package applications at the XML level
-%     (eg with XInclude, or as an external entity) without the
-%     need for manual cutting and pasting;
-% \item \label{xmltools}There is a very wide range of software (editors and
-%     processors, both free and non-free) available to handle
-%     XML documents, including a lot of useful tools for
-%     document management and information extraction.
+% \item Prefixed local variables with CPK\par
+% \item CTAN candidate\par
 % \end{itemize}
-% Everything comes at a cost. The drawbacks of using XML for
-% this include:\par
+% \subsection*{v.1.18 (2020-04-01)}
 % \begin{itemize}
-% \item It's another language to learn. Despite being so
-%     widespread, it's not yet a common skill. In particular,
-%     programmers dislike XML because it's a markup language,
-%     not a programming language, and the syntax is different
-%     from that of programming languages;
-% \item Although there is plenty of software for editing XML,
-%     it is not well-developed for text documents in synchronous
-%     typographic form (often called
-%     `WYSIWYG'); even the best or most
-%     expensive editors are designed for XML experts, not for
-%     the average user.
+% \item Split project into \textsf{classpack}
+% and \textsf{classpack-dev}\par
+% \item Replaced \texttt{@conformance}
+% with \texttt{@YYYY-MM-DD} on all
+% \texttt{date} elements in the revision history. This
+% meant a complete regression run after editing all
+% source masters to use this change\par
+% \item Fixed bug in makechapapp where it failed to add
+% the filetype before substringing the full name of the
+% document\par
 % \end{itemize}
-% \subsection{Contents}
-% The \emph{ClassPack} framework is
-%   enabled by two principal software components:\par
-% \begin{enumerate}
-% \item An XML vocabulary (the
-%       \emph{DocBook}~{\small DTD}\index{DTD} 
-%       or Schema) used for naming the component parts of
-%       documentation and code, and specifying where they belong
-%       and how they fit together;
-% \item An XSLT2 script to implement the logic of
-%       combination and separation needed to create the
-%       {\ttfamily{}.dtx} and {\ttfamily{}.ins}
-%       files.
-% \end{enumerate}
-% The XML vocabulary used is
-%   \emph{DocBook}, which is in widespread
-%   use for the documentation of computer systems, and is
-%   well-supported on all platforms. The current system uses
-%   version 5. Although it is highly modular and easily adapted
-%   for many purposes, only a few minor changes have been made
-%   for its use here, but a number of element types have been
-%   put to uses not envisaged by the developers.\par
-% This habit of using (some say, abusing) XML markup for
-%   different purposes is very common, and often deprecated
-%   because it is usually undocumented. This document explains
-%   what has been [ab]used and for what reasons. Once this
-%   system settles down, a more formal expression of the
-%   vocabulary can be made from the RNG source, removing the
-%   parts that are not required, and making it simpler to edit
-%   with.\par
-% The adaptation of \emph{DocBook} in
-%   this version subsists mainly in the addition of some
-%   attributes and entity declarations to allow the conversion
-%   to \LaTeX{} of special characters and other features that
-%   would otherwise involve extensive re-parsing of the
-%   character data content (text). The changes also implement a
-%   few modifications to the way the \LaTeX{} code is output by
-%   the XSLT2 program for typographical purposes.\par
-% As an example, the entity defining the em rule character
-%   \texttt{\&mdash;} is declared as a \LaTeX{}
-%   tie (non-breaking space) followed by an em rule followed by
-%   a normal space (\verb|~---␣|), so that it
-%   can be used between words~--- like this~--- without the
-%   need to worry about special spacing in the XML, or the
-%   inadvertent breaking of a line before the rule:\par

-can be used between words&mdash;like this&mdash;without the
-\end{lstlisting}
-% \iffalse
-%</ignore>
-% \fi
-% If a
-%   document style requires the use of unspaced dashes, all that
-%   needs changing is the entity declaration, not the whole
-%   document.\par
-% The current driver in Document Type
-%     Definition~(\textsc{dtd})\index{Document Type Definition|see{DTD}}\index{DTD|textbf} format is listed in \vref{savedtd}, and is distributed as file
-%   {\ttfamily{}doctexbook.dtd} so that it can be
-%   referenced as such in a document without having to copy and
-%   paste the declarations into every document.\par
-% \subsection{Invocation}\label{invocation}
-% To create or edit a \emph{ClassPack}
-%   XML document you must have the
-%   \emph{ClassPack} DTD
-%   \emph{and} the DocBook DTD installed and known
-%   to your XML editor. The DTD customisation file,
-%   {\ttfamily{}docbooktex.dtd} is distributed with this
-%   package; an RNG schema version will be available in the
-%   future.\par
-% With the DTD, the standard procedure is to specify it in
-%   the first line of your XML document. Your class or package
-%   documents must therefore start with a Document Type
-%   Declaration. This can specify the Formal
-%     Public Identifier~(\textsc{fpi})\index{Formal Public Identifier|see{FPI}}\index{FPI|textbf} and the filename of the
-%   DTD:\par
-% \iffalse
-%<*ignore>
-% \fi
-\begin{lstlisting}[language=XML]
-<?xml version="1.0"?>
-<!DOCTYPE book PUBLIC 
-  "+//Silmaril//DTD DocBook 5.0 for DocTeX//EN" 
-  "doctexbook.dtd">
-\end{lstlisting}
-% \iffalse
-%</ignore>
-% \fi
-% or
-%   you can omit the {\small FPI}\index{FPI} and specify the DTD as a \texttt{SYSTEM} keyword instead:\par
-% \iffalse
-%<*ignore>
-% \fi
-\begin{lstlisting}[language=XML]
-<?xml version="1.0"?>
-<!DOCTYPE book SYSTEM "doctexbook.dtd">
-\end{lstlisting}
-% \iffalse
-%</ignore>
-% \fi
-% The DTD file {\ttfamily{}doctexbook.dtd} can be
-%   anywhere on your system: in these examples it is assumed to
-%   be in the same directory as your document. If you store it
-%   elsewhere, just give the full filepath, for example:\par
-% \iffalse
-%<*ignore>
-% \fi
-\begin{lstlisting}[language=XML]
-<?xml version="1.0"?>
-<!DOCTYPE book SYSTEM "/usr/local/lib/xml/dtds/doctexbook.dtd">
-\end{lstlisting}
-% \iffalse
-%</ignore>
-% \fi
-% When you open a document starting like this, a
-%   conformant XML editor will look for
-%   {\ttfamily{}doctexbook.dtd} and read it, so that it
-%   then knows the names of all the element types that you can
-%   use, and how they fit together into a document.\par
-% \subsection{Document structure}
-% Every XML document must have one outermost enclosing
-%   element (the `root' element) which
-%   holds everything else. The root element type used in a
-%   ClassPack document is \texttt{book}, as described in
-%   detail in \vref{setup}.\par
-% Within the \texttt{book} element, the
-%   \emph{metadata} (information about the
-%   document) is held in an \texttt{info} element, the
-%   \emph{user documentation} in a \texttt{part}
-%   element with the ID of \texttt{doc}, and the
-%   \emph{annotated code} in a second
-%   \texttt{part} element, with the ID of
-%   \texttt{code}.\par
-% \iffalse
-%<*ignore>
-% \fi
-\begin{lstlisting}[language={[DocBook]XML}]
-<?xml version="1.0"?>
-<!DOCTYPE book SYSTEM "doctexbook.dtd">
-<book>
-  <info>...</info>
-  <part xml:id="doc">...</part>
-  <part xml:id="code">...</part>
-  <part xml:id="files">...</part>
-</book>
-\end{lstlisting}
-% \iffalse
-%</ignore>
-% \fi
-% An optional third \texttt{part} with the ID of
-%   \texttt{files} can be used to include ancillary files that
-%   are to be recreated as-is, without separate annotation or
-%   display, such as sample data or example documents (see \vref{ancfiles}).\par
-% Ancillary files that require annotating must go in the
-%   \texttt{code} part as described in
-%   \vref{secfiles}.\par
-% \subsubsection{User documentation}
-% The documentation for the end user is descriptive text
-%     which explains how to use the package or class. The main
-%     division within a ClassPack \texttt{part} is the
-%     \texttt{chapter}, which can contain \texttt{sect1}
-%     sections, which can contain \texttt{sect2} subsections,
-%     and so on, as described in
-%     \vref{hierarchy}. User documentation must go in
-%     a \texttt{chapter} and its sub-elements: it must not be
-%     directly in the \texttt{part}.\par
-% (Because the \textsf{latexdoc} package is
-%     based on the \textsf{article} package, the
-%     ClassPack \texttt{chapter}\thinspace{}s become
-%     \textsf{latexdoc}~{\ttfamily{}\textbackslash{}section}s; 
-%     the ClassPack \texttt{sect1}\thinspace{}s become
-%     \textsf{latexdoc}~{\ttfamily{}\textbackslash{}subsection}s, 
-%     and so on.)\par
-% \paragraph{Structure}
-% Your document can use most of the conventional
-%       structural features of any DocBook document: paragraphs,
-%       lists, figures, tables, and examples of code (both
-%       illustrative and for extraction) as described in \vref{pool}. Most of the specialist constructs of
-%       DocBook are not implemented in ClassPack except for a
-%       few used in the \texttt{info} section for setup
-%       purposes. You should refer to the list of markup in
-%       \vref{pool} for exactly which element types
-%       do what.\par
-% \paragraph{Inline markup}
-% Within the text you can use much of the conventional
-%       semantic markup provided in
-%       \emph{DocBook} as described in \vref{flow}.\par
-% \subsubsection{Annotated code}
-% In the \texttt{code} Part, you annotate the inner
-%     workings of your package or class. The use of the
-%     \texttt{chapter} and \texttt{sect1} divisional
-%     structure is also mandated here: everything within the
-%     chapters is regarded as the package or class.\par
-% Your code can be explained in fragments, either as
-%     alternating \texttt{para} and \texttt{programlisting}
-%     elements, or as \texttt{annotation} elements, each one
-%     describing a single macro or environment or other object,
-%     and containing \texttt{para} and
-%     \texttt{programlisting} (this makes it indexable). See
-%     the examples in \vref{pool}.\par
-% \subsubsection{Ancillary files}\label{ancfiles}
-% There are two types of extractable ancillary
-%   file:\par
-% \begin{itemize}
-% \item Ancillary files to be annotated and extracted
-% along with the class or package file must each go in
-% their own \texttt{appendix} element immediately
-% after the last of the \texttt{chapter} element of
-% the package or class in the \texttt{code}
-% Part
-% \item Ancillary files which just need to be extracted
-% whole, and do not have any separate documentation must
-% go in the \texttt{files} Part as described in \vref{ancfiles}.
-% \end{itemize}
-% \subsection{Tooling up}
-% You need the following tools:\par
-% \begin{itemize}
-% \item an XML editor: I use
-%       \emph{Emacs} with
-%       \emph{psgml-mode} and
-%       \emph{xxml-mode}, but any competent
-%       XML editor will do
-% \item an XSLT2 processor: I use
-%       \emph{Saxon} (this also means I
-%       installed \emph{Java})
-% \item a full installation of \LaTeX{}
-% \item a PDF reader
-% \item XML tools: I find the
-%       \emph{LTxml2} toolkit from Edinburgh
-%       University invaluable for ad-hoc querying of
-%       documents.
-% \end{itemize}
-% \clearpage
-% \section{Setting up a ClassPack document}
-% Using \emph{ClassPack} to create and
-% maintain \LaTeX{} classes and packages requires the following
-% initial steps. These are only done once, at the start of a new
-% class or package. A few items need periodic updating, such as
-% the version number, when it changes; the revision history; and
-% the list of packages, as and when needed.\par
-% \begin{enumerate}
-% \item setting up the configuration (see \vref{setup})
-%   to specify the name, date, version, type, audience, status,
-%   and other key metadata;
-% \item setting up the documentary metadata (see \vref{metadata}) such as the title, author, contact
-%     details, abstract, and the initial entry in the revision
-%     history;
-% \item setting up the list of packages (see \vref{constraints}) required for 
-%      \begin{enumerate*}[label=\emph{\alph*})]
-% \item the documentation (see \vref{docpax})
-% and 
-% \item the class or package itself (see \vref{classtypax})
-% \end{enumerate*}, plus any additional initialization
-%     commands needed for the documentation.
-% \end{enumerate}
-% \emph{Note particularly that the list of packages
-%   required by the class or package itself is
-%   \emph{not} stored inline to the code of the
-%   class or package. It is stored separately for reasons that
-%   are explained in detail in \vref{constraints}.}\par
-% \subsection{Configuration and setup}\label{setup}
-% The \texttt{book} element is the outermost container
-%   for the document. It is used to carry the configuration
-%   information in attributes, for example:\par

-% \begin{description}[style=unboxed]
-% \item[\texttt{xml:id}\thinspace:]\label{rootid}This \textsc{must} be the
-% name of the class or package. It will be used as the
-% \LaTeX{} filename (with {\ttfamily{}.cls} or
-% {\ttfamily{}.sty} and
-% {\ttfamily{}.ins} added automatically), so it
-% \textsc{should} be all lowercase
-% and \textsc{must} consist of
-% letters, digits, and hyphens only, starting with a
-% letter.\par
-% The XML rules for IDs require this restriction,
-% which currently makes it impossible to use ClassPack
-% to maintain a class or packages whose name begins with
-% a digit.
-% \item[\texttt{arch}\thinspace:]\label{arch}The `architecture' of the
-% document, which defines the type of file you are going
-% to produce; this must be either \texttt{"class"} or \texttt{"package"}, corresponding
-% exactly with the value of the \texttt{userlevel}
-% attribute below.
-% \item[\texttt{userlevel}\thinspace:]\label{userlevel}The file type of the class or package document;
-% this must be either {\ttfamily{}cls} or
-% {\ttfamily{}sty}, corresponding
-% exactly with the value of the \texttt{arch}
-% attribute above.
-% \item[\texttt{version}\thinspace:]The major version of the class or package.
-% Conventionally, development (α) or pre-release
-% (β) versions of software start at version
-% zero.
-% \item[\texttt{revision}\thinspace:]\label{revno}The sub-version or release of your class or
-% package. This is combined with the major version
-% number, separated by a dot, to produce the complete
-% version number.\par
-% The most recent revision history entry gets tested
-% against this when the file is processed, and an error
-% message is displayed if the version numbers do not
-% match, as a warning that you have updated one without
-% updating the other, and may therefore have forgotten
-% to document a change (see the \texttt{revision}
-% element in
-% `\textbf{\texttt{revhistory}}', the last item in the list in \vref{revhist}).
-% \item[\texttt{status}\thinspace:]The development status of the class or package, eg
-% \texttt{"alpha"}, \texttt{"beta"}, \texttt{"candidate"}, \texttt{"draft"}, \texttt{"final"}, etc.
-% \item[\texttt{conformance}\thinspace:]The \TeX{} format required to process the
-% {\ttfamily{}.dtx} document. Only the value
-% \texttt{"LaTeX2e"} is supported at
-% the moment.
-% \item[\texttt{condition}\thinspace:]The version of the format identified in \texttt{conformance}, expressed as an
-% ISO date (\texttt{"yyyy-mm-dd"}).\par
-% Note that this is \emph{not} in the
-% \LaTeX{} format
-% ({\ttfamily{}yyyy/mm/dd}).
-% \item[\texttt{os}\thinspace:]The operating system[s] for which the class or
-% package is relevant. Currently, only the value \texttt{"all"} is supported.
-% \item[\texttt{audience}\thinspace:]The licence under which the class or package is
-% made available. For normal publicly-available \LaTeX{}
-% classes or packages which will be uploaded to CTAN,
-% use the value \texttt{"lppl"}
-% (\LaTeX{} Project Public Licence).\par
-% A copy of the LPPL is distributed with ClassPack
-% in a file called {\ttfamily{}lppl.xml}, which
-% must be copied or soft-linked (aliased) to each
-% directory in which you process ClassPack
-% documents.\par
-% Classes or packages for private or commercial use
-% will probably need to use another value, but it is
-% used as a filename, so a {\ttfamily{}.xml}
-% file with that name must exist in the directory in
-% which your ClassPack document is processed. It must
-% contain a
-% \emph{DocBook}~\texttt{chapter} 
-% element containing the text of the licence, which will
-% be included at the end of the documentation.
-% \item[\texttt{security}\thinspace:]The checksum value emitted by
-% \textsf{ltxdoc} when it processes your class
-% or package to format your documentation. See the
-% documentation for the \textsf{ltxdoc} package for details.\par
-% Setting this to zero avoids the \LaTeX{} error
-% message during early development, when every edit
-% would change the checksum. As with the version values,
-% you must update this value, if non-zero, to match the
-% one that \textsf{ltxdoc} reports.
-% \item[\texttt{vendor}\thinspace:]Your name, or the name of the organisation
-% responsible for the work on this class or package.
-% \item[\texttt{remap}\thinspace:]Any options to pass to the
-% \textsf{ltxdoc} package, such as
-% \textbf{\texttt{a4paper}}, \textbf{\texttt{12pt}},
-% etc.\par
-% This, and the following \texttt{annotations}
-% attribute, make it easier to change the global
-% formatting of the documentation.
-% \item[\texttt{annotations}\thinspace:]Any \LaTeX{} commands required for global
-% application at the start of the documentation that
-% cannot easily be included anywhere else (eg
-% {\ttfamily{}\textbackslash{}raggedright},
-% {\ttfamily{}\textbackslash{}sffamily}, etc).
-% \item[\texttt{xml:base}\thinspace:]The name of the \emph{subdirectory}
-% where the resulting {\ttfamily{}.cls} or
-% {\ttfamily{}.sty} file should be installed in
-% a TDS-compliant \TeX{} installation, relative to the
-% {\ttfamily{}texmf/tex/latex} directory of the
-% tree. For most packages, this means the name of the
-% directory you want created by the installation
-% {\ttfamily{}.tds.zip} file, in which the
-% {\ttfamily{}.cls} or {\ttfamily{}.sty}
-% file will be put.
-% \item[\texttt{xlink:role}\thinspace:]\label{selfspec}\textsc{Optional}. If this
-% is set to a value, then the package being written will
-% be included in the setup for the documentation
-% (perhaps so that it can be used in examples), with the
-% value of this attribute being used as the optional
-% argument to the generated
-% {\ttfamily{}\textbackslash{}usepackage} command.\par
-% If the package is required with no options, use
-% this attribute but set it to null (\texttt{""}). The date constraint is
-% added automatically, using the current package date as
-% defined by the most recent entry in the
-% \texttt{revhistory}.\par
-% Note that this only works for packages, not
-% classes. Classes cannot not be documented using
-% themselves.
-% \end{description}
-% It is essential to get these values correct, otherwise
-%   subsequent processing will produce unexpected
-%   results, or no results at all.\par
-% \subsection{Metadata}\label{metadata}
-% The titling, specification of packages (separately for
-%   the documentation and for the class or package itself),
-%   revision history, abstract, copyright, and availability are

-% \subsection{Packages and related commands}\label{constraints}
-% As mentioned above, the \texttt{cover} element is used
-%   to provide a place where packages and other \LaTeX{}
-%   preliminaries can be specified. Using this structure means
-%   each entry is separately editable, and the same structure is
-%   used both for packages for the documentation
-%   \emph{and} packages for the class or package
-%   itself.\par
-% It would of course have been possible just to allow a
-%   slab of \LaTeX{} code at these points, but that would have made
-%   commenting and documentation harder, and would also have
-%   made it more difficult to perform an XML
-%   element-copy--element-paste or an XInclude when using
-%   one package or class's settings as the basis for another.\par
-% The most important reason is that specifying package
-%   lists as separately-identifiable blocks makes it possible to
-%   automate the invocation of frequently-used packages,
-%   parameters, options, or settings which you may store
-%   separately for re-use (see \vref{autospec}) by
-%   adding your own modifications that you like to have included
-%   whenever you use a particular package.\par
-% In particular, the
-%   \emph{autopackage} feature added to
-%   ClassPack in v0.74 means that most packages needed for
-%   documentation are now detected automatically on the basis of
-%   features you use in your documentation, making it
-%   unnecessary to specify them by hand. For example, if you use
-%   compact lists, ClassPack will detect this and add the
-%   \textsf{enumitem} package for you.\par
-% The XSLT2 program also uses this markup in order to
-%   modify the behaviour of the \LaTeX{} code at several points
-%   (such as fixing the broken abstract formatting when the
-%   \textsf{parskip} package is used).\par
-% There are at least two, possibly four, sections in the
-%   \texttt{cover} element where the packages, commands, and
-%   other data can be defined:\par

-% See \vref{autospec} for details of how to

-% \subsubsection{Automated settings for declared packages}\label{autospec}
-% There are several reasons for automating package setup:\par
-% \begin{itemize}
-% \item Many \LaTeX{} authors and designers have
-% `favourite' settings that they
-% like to use every time they specify a particular
-% package.
-% \item Some options have now become the \emph{de
-%   facto} convention for their package,
-% (for example, the \textbf{\texttt{T1}} option on the
-% \textsf{fontenc} package).
-% \item There are commands that need to be used whenever a
-% particular package is invoked (for example, the
-% \textsf{makeidx} package means you need to
-% add the {\ttfamily{}\textbackslash{}makeindex} command to the
-% Preamble).
-% \item Some packages are only needed in the documentation
-% if a particular formatting feature is used (for
-% example compact list spacing requires the
-% \textsf{enumitem} package). This avoids you
-% having to remember to include a specific package when
-% you use such a feature; and to remove it if you cease
-% to use the feature.
-% \end{itemize}
-% To help automate these, an ancillary (lookup) file
-%     called {\ttfamily{}prepost.xml} is used, which
-%     is a \emph{DocBook} document with a
-%     \texttt{refsection} root element type containing two
-%     \texttt{procedure} elements, shown below.\par
-% The {\ttfamily{}prepost.xml} file must be in

-% The commands are specified with the command name

-% In giving the commands (control sequences) that you

-%     {\ttfamily{}doctexbook.dtd} used for your normal
-%     class or package {\small XML} document. A sample
-%     is included in the \textsf{classpack}
-%     distribution.\par
-% The {\ttfamily{}readme.xml} file  uses the
-%     \texttt{olink} element type to act as a placeholder for
-%     transcluded atomic information from the main document
-%     (pending implementation of the proposed DocBook
-%     Transclusions method). This element must have a
-%     \texttt{targetptr} and a \texttt{type} attribute
-%     specifying (respectively) the name of the element type and
-%     the relevant attribute in the main document. For example,

-% Two other element types have also had
-%     \texttt{targetptr} and \texttt{type} attributes
-%     added: \texttt{sect1} and \texttt{anchor}. These are
-%     used to specify the inclusion of whole sections or
-%     fragments of the main document, such as the Abstract or
-%     the Copyright.\par
-% The text is reformatted in plain text, omitting all
-%     markup. Only a few element types have been implemented for
-%     this in this version: see the ancillary XSLT2 routines in
-%     {\ttfamily{}db2plaintext.xsl} for details.\par
-% The resulting {\ttfamily{}README} file
-%     includes the Abstract from your class or package
-%     {\small XML} document as the first section. The
-%     {\ttfamily{}db2plaintext.xsl} program uses a
-%     template called \DescribeTemplate{normtext}\texttt{normtext} to
-%     reformat text. This handles the conversion of entities
-%     which occur in your Abstract (those declared in
-%     {\ttfamily{}doctexbook.dtd}): by default, \texttt{\&TeX;}, \texttt{\&LaTeX;}, and \texttt{\&thinsp;} are catered for, but if
-%     you use any others, you must modify the code in this
-%     template to deal with them, using a nested
-%     \DescribeFunction{replace()}\texttt{replace()} function.\par

-% \section{Using \emph{ClassPack}}\label{content}
-% The body of your docmentation is held in a \texttt{part}
-% element with the \texttt{xml:id} attribute
-% set to \texttt{"doc"}.\par
-% The tag-set of \emph{DocBook} is very
-% large, and only a part of it is needed for this purpose,
-% although support for additional elements is easily added in
-% the XSLT2 program.\par
-% The following sections describe the elements that are
-% currently supported, for the hierarchical structure (chapters,
-% sections, subsections, etc); the block-level structure
-% (tables, figures, lists, etc; what
-% \emph{DocBook} refers to as the
-% `pool') and for the inline markup (element types
-% in mixed content, used mostly in paragraph-like
-% situations).\par
-% \subsection{Hierarchical markup}\label{hierarchy}
-% The outline top-level structure is described in \vref{invocation} and \vref{setup}.\par
-% The \texttt{part}\thinspace{}s do not have any title or direct
-%   textual content themselves: they just act as containers to
-%   keep the user documentation separate from the documented
-%   code and any other files that may be stored and
-%   extracted.\par
-% Within a \texttt{part}, the major subdivision is the
-%   \texttt{chapter}, which translates to a
-%   {\ttfamily{}\textbackslash{}section} in the {\ttfamily{}.dtx}
-%   file. You should use the \texttt{chapter} element as your
-%   major structural division. Each part (user documentation,
-%   documented code, and additional files) must have at least
-%   one chapter.\par
-% Within chapters, the sections, subsections, and lower
-%   structural divisions are identified with \texttt{sect1},
-%   \texttt{sect2}, and so on. You can use as many or as few
-%   of these as you feel you need to organise your writing. In
-%   the documented code, it is a good idea to modularise the
-%   class or package, so that you can describe each part of it
-%   in a logical and consistent manner.\par
-% The nested arrangement of chapters containing sections
-%   conaining subsections should already be familiar to \LaTeX{}
-%   users, although \LaTeX{} itself only uses headings as
-%   separators, and has no physical
-%   `containment' of the hierarchical
-%   divisions of a document in the way that it does for the
-%   block-level structures (environments).\par
-% Each of these hierarchical divisions must have a
-%   \texttt{title} element (see `\textbf{\texttt{title}}', the first item in the list in \vref{title}),
-%   and can also have an \texttt{xml:id}
-%   attribute to act as a target (like a \LaTeX{}
-%   {\ttfamily{}\textbackslash{}label}) for cross-referencing (see `\textbf{\texttt{xref}}', the last item in the list in \vref{xref}).\par

+% \textsf{classpack}, is responsible only for

-%       and setting the \texttt{date} subelement's \texttt{conformance} attribute to
-%       today's date in ISO format
-% \item after processing the document once, set the
-%       \texttt{book} root element's \texttt{security} attribute to the
-%       checksum displayed by \LaTeX{}
-% \item process the document again (run the
-%       {\ttfamily{}build} script again)~--- the

+% \item Two-column index instead of three-column\par
+% \item Dark Blue colour for annotated code\par
+% \item Recalculation of the left-hand margin in
+%       documentation to accommodate long variable names\par
+% \item Wider space for the section numbers and page numbers
+%       in the Table of Contents, and ragged-right setting for
+%       section titles to prevent hyphenation\par
+% \item Appendixes (used for annotated code for ancillary
+%       files) are styled at section level, not chapter

-% \section{The \emph{db2dtx} program}\label{db2dtx}
-% While the core of your class or package is the
-% \emph{DocBook} XML document, the core of
-% the \emph{classpack} system is the program
-% that turns your XML into {\ttfamily{}.dtx} and
-% {\ttfamily{}.ins} files for distribution as combined
-% code and documentation.\par
-% The \emph{db2dtx} program is written
-% in XSLT2, a declarative language for processing XML. It
-% consists of a set of templates, each of which matches a
-% pattern in the XML document, usually an element type, or an
-% element type in a particular position or with a particular
-% attribute value or subelement.\par
-% For example, there is a template which matches the
-%       \texttt{biblioref} element whenever it occurs. This puts three
-% things into the output:\par
-% \begin{enumerate}
-% \item the command \verb|\cite{| with its
-%     opening curly brace;
-% \item the value of the link to the bibliographic
-%     entry;
-% \item the closing \verb|}| curly
-%     brace.

-\end{lstlisting}
-% \iffalse

-% \fi
-% The advantage of using a declarative language is that you
