+% documents should be of the same class
+% (e.g., all \Lpack{article}s or all \Lpack{report}s).
+% The class requires the \Lpack{keyval} package.
+%
+% The accompanying \Lpack{combinet} and \Lpack{combnat} packages

+% \section{Introduction}
+%
+% Questions about making a collection of different articles into a single
+% document
+% seem to pop up fairly regularly on the
+% \texttt{comp.text.tex} newsgroup.
+% The \Lpack{combine} class provides a solution for this problem.
+%
+% 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}.
+%
+% Section~\ref{sec:usc} describes the usage of the \Lpack{combine} class and
+% Sections~\ref{pack} and~\ref{natpack} describe the \Lpack{combinet}
+% and \Lpack{combnat} packages.
+% Commented source code for the class is in Section~\ref{sec:code}.
+% The class requires the \Lpack{keyval} package to be available.
+% Commented source code for the \Lpack{combinet} package is in
+% Section~\ref{packcode}, and for \Lpack{combnat} is in
+% Section~\ref{natpackcode}.
+%
+% Note that the version number and date given for this file does not
+% necessarily match version numbers or dates for the class and packages.
+%
+% \section{The \Lpack{combine} class} \label{sec:usc}
+%
+% The \Lpack{combine} class enables a group of individual
+% \LaTeX{} documents to be imported and assembled into a single document. All
+% the individual documents should be of the same class (e.g., all
+% \Lpack{article} or all \Lpack{report}).
+%
+% Sectioning, cross-referencing, bibliographies, etc., are local within
+% each imported document. Various means are provided for controlling local
+% Table of Contents, the format of |\maketitle|, and so on, without having
+% to make any changes to the original of an imported document.
+%
+% Here is a simple example file which might be the skeleton for a
+% conference proceedings.
+% \begin{verbatim}

+%
+% \subsection{Class options}
+%
+% As well as providing all the class options appropriate for
+% the class of the individual documents, the \Lpack{combine}
+% class provides the following additional options:
+% \begin{itemize}
+% \item \Lopt{book}, \Lopt{report} and \Lopt{letter}.
+% By default the \Lpack{article}
+% class is assumed for both the main and the imported documents.
+% These options change the class to \Lpack{book}, \Lpack{report} or
+% \Lpack{letter}, respectively.
+% \item \Lopt{colclass=\meta{class}}. This option changes
+% the `classes' to \meta{class}. For example, specifying
+% |colclass=phdthesis| will use the \Lpack{phdthesis}
+% class\footnote{Whatever that is.} definitions
+% throughout the entire document.
+%
+% Note that if you use this option there are likely to be \LaTeX{}
+% warnings about \texttt{Unused global option(s): [colclass=\ldots]}.
+%
+% \item \Lopt{classes}. This option enables the imported documents
+% to be of different classes. For example, embedding a letter
+% into a compendium of articles. Using this option may
+% induce a plethora of \LaTeX{} errors and the printed results
+% may be unpredictable. If this happens, try hitting `q' to
+% put \LaTeX{} into
+% its `quiet batch' processing mode and then examine the typeset result
+% for usability.
+%
+% Different classes of imported documents should not be mixed
+% within a single |papers| environment. Also, imported documents
+% whose class is the same but which differs from the main class
+% should be within a single |papers| environment. For example,
+% if several letters are to be imported into a collection
+% of articles, the letters must not be scattered between different
+% |papers| environments, although the imported articles can be
+% scattered.
+%
+% \item \Lopt{packages}. By default all |\usepackage| commands in
+% imported documents are ignored. If this is not desired,
+% then the \Lopt{packages} option will enable the imported
+% |\usepackage| commands(s). If this option is used, then only
+% the first occurrence of a package is actually used and is not
+% available to any later imported documents.
+%
+% Generally speaking, it is advisable to put all |\usepackage|
+% commands into the preamble of the main document.
+%
+% \item \Lopt{layouts}. By default, a single setting of the
+% page layout is used throughout the document. The \Lopt{layouts}
+% option takes account of any changes to the |\textwidth|,
+% |\textheight|, etc., in the imported documents.
+%
+% \item \Lopt{folios}. The page numbers are sequential throughout
+% the document. When the |plain| page style is used, the
+% \Lopt{folios} option will display the
+% local page numbers of imported documents as well as the
+% the main page number. This may have unfortunate consequences
+% on the page numbers in ToC, etc., entries as they may well
+% refer to local rather than global page numbers.
+%
+% \item \Lopt{notoc}. Disables the inclusion of a Table of Contents
+% in any imported document.
+% \item \Lopt{nolof}. Disables the inclusion of a List of Figures
+% in any imported document.
+% \item \Lopt{nolot}. Disables the inclusion of a List of Tables
+% in any imported document.
+% \item \Lopt{maintoc}. Adds all imported documents ToC, LoF, LoT, etc.,
+% entries to the main document ToC, LoF, \ldots
+% \item \Lopt{notitle}. Disables title printing by any |\maketitle|
+% in any imported document.
+% \item \Lopt{noauthor}. Disables author printing by any |\maketitle|
+% in any imported document.
+% \item \Lopt{date}. By default, date printing by any |\maketitle|
+% in any imported document is disabled. This option causes
+% the date(s) to be printed.
+% \item \Lopt{nomaketitle}. Disables all printing by any |\maketitle|
+% in any imported document.
+% \item \Lopt{nopubindoc}. Disables the printing of the |\published|
+% information within an imported document.
+% \item \Lopt{nopubintoc}. Disables the printing of the |\published|
+% information within the main ToC.
+% \item \Lopt{onebib}. Disables imported bibliographies and puts all
+% citations in the main document's bibliography.
+% \item \Lopt{combinedbib}. Individual imported bibliographies and
+% also all citations put into the main document's bibliography.
+% \end{itemize}
+%
+% The \Lpack{combine}
+% class may be able to incorporate any class of imported documents by
+% setting an appropriate value for the \Lopt{colclass} option and perhaps
+% doing some additional work.
+%
+% For example, if you want to have a collection of examination papers
+% which were each is originally produced using the \Lpack{exam} class,
+% then start off with: \\
+% |\documentclass[...,colclass=exam]{combine} | \\
+% The \Lpack{exam} class, though, does a couple of things that prevent
+% \Lpack{combine} and \Lpack{exam} from working well together:
+% \begin{itemize}
+% \item \Lpack{exam} has its own version of |\section| which is totally at
+% odds with the normal \Lpack{article} definition, and |\section*| is
+% used by the |\tableofcontents| command.
+% \item \Lpack{exam} does wonderful things at the end of a document. This
+% is alright for imported documents in a |papers| environment but is an
+% abject failure at the final end of the main document.
+% \end{itemize}
+%
+% To get round these problems, put the following in the preamble to
+% the main document:
+% \begin{verbatim}
+% \makeatletter
+% \let\oldsection\section % keep exam's definition of \section
+% \renewcommand{\section}{% % article's definition of \section
+% \@startsection{section}{1]{\z@}%
+% {-3.5ex \@plus -1ex \@minus -.2ex}%
+% {2.3ex \@plus .2ex}%
+% {\normalfont\Large\bfseries}}
+% \makeatletter
+% \end{verbatim}
+% and in the document put: \\
+% |\let\section\oldsection| \\
+% immediately before the first |papers| environment.
+%
+% For the end document problem, put:
+% \begin{verbatim}
+% \makeatletter
+% \let\@enddocumenthook\@oldenddocumenthook
+% \makeatother
+% \end{verbatim}
+% immediately before the main document's |\end{document}|.
+%
+%
+% \subsection{Class commands and environments}
+%
+% Within a \Lpack{combine} class document you can use any commands
+% that are supported by the selected class.
+% The following additional commands and environments are also
+% provided.
+%
+% \DescribeEnv{papers}
+% The environment |\begin{papers}[|\meta{text/code}|]...\end{papers}|
+% provides a wrapper around imported file(s). Effectively, it modifies
+% any |\documentclass| command or |document| environment within an
+% imported file so that \LaTeX{} does not stop with an error at meeting
+% these, or preamble-only commands like |\usepackage|, in the middle
+% of a document.
+%
+% The optional argument is executed immediately at the start of
+% the environment and its default value is |\cleardoublepage|.
+% To avoid any forced page breaking you can call the environment with
+% an empty optional argument (e.g., |\begin{papers}[]|).
+%
+%
+% \DescribeMacro{\import}
+% The command |\import{|\meta{texfile}|}| is a cross between the |\input|
+% and |\include| commands, and should only be used within a |papers|
+% environment. \meta{texfile} is the name of a \LaTeX{} file \emph{without}
+% the |.tex| extension. For example, |\import{fred}| will attempt to
+% read in a file called |fred.tex|. The \meta{texfile} should be a
+% complete \LaTeX{} document file, from |\documentclass...| to
+% |\end{document}|. The contents of \meta{texfile} will be typeset in
+% the document at the point where it is imported, including any document
+% title (via a |\maketitle|), Table of Contents, \ldots, Bibliography, etc.
+%
+% \DescribeMacro{\maketitle}
+% The \Lpack{combine} class provides a |\maketitle| command, together with
+% |\title|, |\author| and |\date| commands like those in the
+% \Lpack{book/report/article} classes. A \Lopt{titlepage} option is only
+% supported if the main class has a \Lopt{titlepage} option. For example,
+% if the main class is \Lpack{article} then both |\maketitle| and the
+% \Lopt{titlepage} option are supported, but if the main class is
+% \Lpack{letter} then only the |\maketitle| command is provided.
+%
+% \DescribeMacro{\maintitlefont}
+% \DescribeMacro{\postmaintitle}
+% \DescribeMacro{\mainauthorfont}
+% \DescribeMacro{\postmainauthor}
+% \DescribeMacro{\maindatefont}
+% \DescribeMacro{\postmaindate}
+% These commands control the typesetting of the main document's |\maketitle|
+% command. The |\title| is processed between the |\maintitlefont| and
+% |\postmaintitle| commands; that is, like: \\
+% |{\maintitlefont \title \postmaintitle}| \\
+% and similarly for the |\author| and |\date| commands. The |\...main...|
+% commands are initialised to mimic the normal result of |\maketitle|
+% typesetting in the \Lpack{article/report} classes.
+% For example, the default definitions of the |\...maintitle...|
+% and |\...mainauthor...| commands are:\par
+% \begin{small}
+% \begin{verbatim}
+% \newcommand{\maintitlefont}{\begin{center}\LARGE}
+% \newcommand{\postmaintitle}{\par\end{center}\vskip 0.5em}
+% \newcommand{\mainauthorfont}{\begin{center}
+% \large \lineskip 0.5em%
+% \begin{tabular}[t]{c}}
+% \newcommand{\postmainauthor}{\end{tabular}\par\end{center}}
+% \end{verbatim}
+% \end{small}\par
+% They can be renewed to obtain different effects, for instance removing
+% the |center| environment from |\...title...| will result in the title
+% being typeset as a normal paragraph.
+%
+% \DescribeMacro{\importtitlefont}
+% \DescribeMacro{\postimporttitle}
+% \DescribeMacro{\importauthorfont}
+% \DescribeMacro{\postimportauthor}
+% \DescribeMacro{\importdatefont}
+% \DescribeMacro{\postimportdate}
+% Without any options, the |\title| and |\author| commands
+% are typeset by |\maketitle| commands in imported documents.
+% Like the main document's |\maketitle|, the typesetting is controlled
+% by these |\...import...| commands. The default definition for
+% the title and author differ a little from the main document style,
+% and are:\par
+% \begin{small}
+% \begin{verbatim}
+% \newcommand{\importtitlefont}{\begin{center}\LARGE\bfseries}
+% \newcommand{\postimporttitle}{\par\end{center}}
+% \newcommand{\importauthorfont}{\begin{center}
+% \large\itshape \lineskip 0.5em%
+% \begin{tabular}[t]{c}}
+% \newcommand{\postimportauthor}{\end{tabular}\par\end{center}}
+% \end{verbatim}
+% \end{small}\par
+% The commands can be renewed to obtain different formatting.
+%
+% Note that if the \Lpack{titling} package is used with the \Lpack{combine}
+% class, the \Lpack{titling} maketitle typesetting commands are unavailable,
+% being replaced by the corresponding \Lpack{combine} commands above. Other
+% aspects of \Lpack{titling}, like the |\thetitle| command, are still
+% available for use.
+%
+% \DescribeMacro{\bodytitle}
+% The |\bodytitle[|\meta{short title}|]{|\meta{long title}|}| command
+% is similar
+% to a |\chapter| or |\section| command, depending on the \meta{class}
+% of document. It may be used for adding a numbered title heading into
+% the main
+% document and ToC for the following |\import{|\meta{texfile}|}|. There
+% is also a starred version of the command, which produces an unnumbered
+% title heading and makes no entry in the ToC. The numbering used for
+% |\bodytitle| is independent from any other numbering sequence.
+%
+% \DescribeMacro{\coltoctitle}
+% \DescribeMacro{\coltocauthor}
+% The two commands |\coltoctitle{|\meta{title}|}| and
+% |\coltocauthor{|\meta{author}|}| are for adding \meta{title} and
+% \meta{author} to the main ToC, where \meta{title} is the compiler's
+% choice for the title of the following |\import{|\meta{texfile}|}|
+% and \meta{author} is for the names of the authors.
+%
+% \DescribeMacro{\published}
+% The command |\published[|\meta{short}|]{|\meta{long}|}| can be used
+% for putting the \meta{long} text into the body of the main document.
+% If the optional argument is not used, then \meta{long} is also added
+% to the main ToC. If the optional argument is used, then \meta{short}
+% instead of \meta{long} is added to the ToC. The expectation is that this
+% will be used for noting the original publication information for an
+% imported document.
+%
+% \DescribeMacro{\pubfont}
+% In the document body the text of the |\published| command is typeset
+% using |\pubfont|. By default this is defined as |{\normalfont\centering}| to
+% give centered text in the normal font. If, for example, you wanted
+% it to be typeset ragged right in an italic font you would do: \\
+% |\renewcommand{\pubfont}{\itshape\raggedright}|
+%
+% \DescribeMacro{\toctitleindent}
+% \DescribeMacro{\tocauthorindent}
+% \DescribeMacro{\tocpubindent}
+% \DescribeMacro{\toctocindent}
+% These are all lengths, and their values can be changed using
+% |\setlength|. They control the extra indentation of an imported
+% document's title, authors, publication information and section
+% headings within the main ToC. The default value of |\toctitleindent|
+% is 0em and the default for the other four is 1.5em. If any values
+% are changed, this must be
+% done before the |\tableofcontents| command in the main document.
+% For example, the title texts are aligned at the left margin;
+% to align them with the default position of authors do: \\
+% |\setlength{\toctitleindent}{1.5em}|
+%
+% \DescribeMacro{\toctitlefont}
+% \DescribeMacro{\tocauthorfont}
+% \DescribeMacro{\tocpubfont}
+% These macros specify the fonts to be used for typesetting the
+% imported titles, authors and publishing information within the main ToC.
+% Their default definitions are: \\
+% |\newcommand{\toctitlefont}{\bfseries}| % bold titles \\
+% |\newcommand{\tocauthorfont}{\itshape}| % italic authors \\
+% |\newcommand{\tocpubfont}{\normalfont}| % normal font for published
+%
+% The class tries to keep any group of title/author/published entries
+% in the ToC on one page, but sometimes TeX will insert a pagebreak anyway.
+% The way of combating this is to make sure that the ToC page is broken
+% \emph{before} the group. You can do this like: \\
+% |\addtocontents{toc}{\protect\pagebreak}| \\
+% |\coltoctitle{...} \coltocauthor{...}| etc.
+%
+% \DescribeMacro{\erasetitling}
+% This macro `undefines' any previous |\coltoctitle|, |\coltocauthor|
+% and/or |\published| commands; it is principally provided for use with the
+% \Lpack{combinet} package.
+%
+%
+% \DescribeMacro{combine}
+% A new |combine| pagestyle is provided. This is like the |plain|
+% pagestyle except that page numbers are put at the bottom outside corner
+% of the page. This is the default pagestyle for the \Lpack{combine}
+% class.
+%
+% Provided a |plain| (or |combine|) page style is used the pages
+% are numbered in sequence throughout the document. If an imported document
+% has any |empty| page style pages these will not be numbered.
+%
+% Unless the \Lopt{folios} option is used, all references to page
+% numbers will be to the global page number. With the \Lopt{folios}
+% options some references will be to global page numbers and some to
+% local page numbers.
+%
+% You can, of course, define your own heading styles; I recommend
+% the \Lpack{fancyhdr} package~\cite{FANCYHDR} if you do this. For example,
+% if you had a collection of papers and you wanted to have the
+% headers on the lefthand pages to have the title of the collection
+% and the righthand pages to have the name of the current author(s), you
+% can do this along the following lines.
+% \begin{verbatim}
+% \documentclass[report,twoside]{combine}
+% \usepackage{fancyhdr}
+% \title{The collection}
+% \author{A. N. Editor}
+% \pagestyle{fancy}
+% \fancyhead[RO]{A. N. Editor}
+% \fancyhead[LE]{The collection}
+% \fancyfoot{}
+% \fancyfoot[LE,RO]{\thepage}
+% \newcommand{\authortochead}[1]{%
+% \coltocauthor{#1}
+% \fancyhead[RO]{#1}

+% Each imported file generates its own \file{.aux}, \file{.toc}, etc.,
+% files. If a BibTeX database is used for the literature references
+% in an imported document, then BibTeX must be run against the imported
+% document, \emph{not} the main document, to resolve the citations.
+% Citations are local to each imported document. There can, of course,
+% also be a bibliography for citations made in the main document, as shown
+% in the example file above.

+%
+% \DescribeMacro{\zeroextracounters}
+% The class attempts to initialise the counters used by each imported
+% document. For example, the figure, equation, etc., counters are zeroed
+% for each document. The |\zeroextracounters| command can be redefined so
+% that it includes the zeroing of any additional counters that might have
+% been introduced in a package or defined by the author. For example,
+% if two different imports both define a (new) counter called, say,
+% |mycounter|, then redefine the command like:
+% \begin{verbatim}
+% \renewcommand{\zeroextracounters}{%
+% \@ifundefined{c@mycounter}{}{\setcounter{mycounter}{0}}
+% }
+% \end{verbatim}
+%
+% \DescribeMacro{\appendiargdef}
+% The (internal) command |\appendiargdef{|\meta{macro}|}{|\meta{stuff}|}|
+% appends \meta{stuff} at the end of the current definition of \meta{macro},
+% where \meta{macro} is the name of a macro (including the backslash)
+% which takes one argument. For example the following are two equivalent
+% definitions of |\mymacro|:
+% \par\begin{small}\begin{verbatim}
+% \newcommand{\mymacro}[1]{#1 is a bagpiper}
+% \appendiargdef{\mymacro}{ and of course is tone deaf}
+% % or
+% \newcommand{\mymacro}[1]{#1 is a bagpiper and of course is tone deaf}
+% \end{verbatim}
+% \end{small}\par
+%
+% \subsection{Imports in subdirectories}
+%
+% Authors may find it convenient to put the LaTeX source files for imported
+% documents into subdirectories of the directory for the main document.
+% Perhaps the easiest way to make this work is to set an environment
+% variable so that LaTeX will look in the subdirectories of the current
+% working directory for files it can't find.
+%
+% I use a teTeX system and can only talk about that distribution.
+% The relevant environment variable, at least for document files, is
+% |TEXINPUTS|. An example setting for this is: \\
+% |TEXINPUTS=.//:${LOCALTEX}//:| \\
+% The fragment |.//| tells LaTeX to look for files in the current directory,
+% and recursively in its subdirectories. The fragment |:${LOCALTEX}//| tells
+% LaTeX to look for files in the place defined by the environment variable
+% |LOCALTEX|, and recursively in its subdirectories. The final |:| tells
+% LaTeX to look in the standard teTeX defined places.

+% \section{The \Lpack{combinet} package} \label{pack}
+%
+% The \Lpack{combinet} (COMBINE Title) package,
+% which should only be used in conjunction
+% with the \Lpack{combine} class, modifies the |\maketitle| command of
+% all imported documents so that the imported document's title and/or
+% author, if
+% defined, are automatically added to the main document's ToC.
+%
+% This is presented as a package rather than as part of the
+% \Lpack{combine} class as some unfortunate side effects may become
+% apparent.
+%
+% If a |\coltoctitle| or |\coltocauthor| command has been given
+% immediately prior to the import, then these will be put into the main
+% ToC instead of the |\maketitle| texts. The |\erasetitling| command can
+% be used to disable any prior |\coltoctitle|, |\coltocauthor| and
+% |\published| commands.
+%
+% The package takes the following options.
+% \begin{itemize}
+% \item \Lopt{nomtitle}. Disable the |\maketitle| title
+% from being added to the main ToC.
+% \item \Lopt{nomauthor}. Disable the |\maketitle| author
+% from being added to the main ToC.
+% \item \Lopt{nothanks}. By default, the contents of a |\thanks| command
+% will be added to the main ToC. This option prevents that, but
+% may have unfortunate side effects if any |\title| or |\author|
+% command has any embedded commands within the text.
+% \item \Lopt{pub}. Put the text of an immediately prior |\published|
+% command after the |\maketitle| typesetting, and add the text to the
+% main ToC after any title or author. Remember that the \Lpack{combine}
+% class options \Lopt{nopubindoc} and \Lopt{nopubindoc} can be used
+% to inhibit printing of |\published| information.
+% \item \Lopt{pubtop}. Put the text of an immediately prior |\published|
+% command at the top of the |\maketitle| typesetting, and add the
+% text to the
+% main ToC after any title or author.
+% \end{itemize}
+%
+% As noted above, embedded commands within a |\title| or |\author| may
+% not transform well if they appear in the main ToC. In such cases you can
+% use |\coltoctitle| or |\coltocauthor| for adding appropriate text to
+% the main ToC, not forgetting to disable these after the import via
+% |\erasetitling|.
+%
+% \section{The \Lpack{combnat} package} \label{natpack}
+%
+% The \Lpack{combine} class and Patrick Daly's \Lpack{natbib}
+% package~\cite{NATBIB}
+% both redefine some of the same basic LaTeX macros, and naturally
+% the redefinitions are incompatible\footnote{Discovered by
+% Thomas Hertweck (\texttt{Thomas.Hertweck@gpi.uni-karlsruhe.de}) in
+% June 2001.}.
+%
+% The \Lpack{combnat} (COMBine NATbib) package hopefully resolves this
+% problem. With the \Lpack{combine} class you use \Lpack{combnat} instead
+% of \Lpack{natbib}. That is, instead of: \\
+% |\usepackage[|\meta{natbib-options}|]{natbib}|, simply do \\
+% |\usepackage[|\meta{natbib-options}|]{combnat}| \\
+% in the preamble of the main document. The package automatically calls
+% the \Lpack{natbib} package with the given \meta{natbib-options} and
+% then redefines some of the \Lpack{natbib} redefinitions to ensure
+% \Lpack{combine/natbib} compatibility.
+%
+% For details on the \meta{natbib-options} and the other facilities,
+% read the \Lpack{natbib} documentation~\cite{NATBIB}.
+%
+%
+% \section{Caveats}
+%
+% \LaTeX{} was designed to typeset a single document, where the document
+% has one and only one |\documentclass| command and one and only one
+% |document| environment. The \Lpack{combine} class attempts to handle
+% a document that has multiple |\documentclass| commands and multiple
+% |document| environments. In order to do this certain parts of the
+% \LaTeX{} kernel code has had to be modified. Unfortunately, to make
+% the usage of \Lpack{combine} completely transparent to the user would
+% require very major surgery, with a high probability that with my skills
+% the patient would die; being able to remove a hangnail does not imply
+% the ability to perform a heart transplant.
+%
+% It is, of course, assumed that each imported document processes without
+% error as an individual document.
+%
+% Essentially, be prepared for the unexpected, usually indicated
+% by a rash of \LaTeX{} error messages about undefined commands or about
+% defining an already defined command. These are usually caused by incorrect
+% grouping.
+%
+% Commands, etc., defined in the main document are available to
+% all imported
+% documents. The |papers| environment forms a group. Commands
+% defined within a group are local to the group and are not visible outside
+% it. Another point is that \LaTeX{} will read the code for any given
+% class or package only once. These facts have some consequences.
+%
+% \begin{itemize}
+% \item The facilities provided by any package that is used by an imported
+% file are only available within the first |papers| environment
+% in which the package is called for. This is why it is recommended
+% that all packages should be called for in the main document.
+%
+% \item Similarly for a class that is not the main class. For example,
+% if the main class is \Lpack{article} and some letters are to be
+% imported, then they must all be in the same |papers| environment.
+% If they are in multiple |papers| environments, then only the first
+% of these will have access to commands like |\address| which are
+% defined by the \Lpack{letter} class (which is only read once and
+% whose facilities are then local to the first of the |papers|).
+%
+% \item An imported document does not form a group (if it did, then only
+% a single letter could be imported into an article class collection).
+% If two imports in a single |papers| seperately use |\new...|
+% commands
+% with the same \meta{name}, then these \meta{name}s will be
+% visible throughout
+% the environment. \LaTeX{} will then normally report trying to define a
+% pre-existing \meta{name}. The solution to this is either: (a) put
+% the imports into different |papers|, or (b) enclose each import
+% within a |\begingroup| \ldots |\endgroup| pair.
+%
+% \end{itemize}
+%
+% Not all problems can be solved by the above methods. For example, consider
+% the case again of importing letters into an article collection. If two
+% letters both define the same \meta{name}, then adding additional grouping
+% will only change the `defining a pre-existing \meta{name}' problem into
+% the `undefined |\address|' problem. A potential solution in this
+% particular case
+% would be to define all the \Lpack{letter} class specific \meta{name}s in the
+% main document.
+%
+% Within a |papers| environment all |\newcommand| and |\newenvironment|
+% commands are replaced by |\providecommand| and |\provideenvironment|
+% respectively. This should stop \LaTeX{} from reporting the pre-existing
+% \meta{name} error from these commands, but one and only one of the
+% definitions will be available. |\newlength| and |\newcounter| commands
+% are handled in the same manner. There is no equivalent for |\newtheorem|,
+% but instead the |\newtheorem| command has been made local instead
+% of global, so cunning use of grouping should be able to circumvent the
+% problem of two seperate authors creating identically named
+% theorems.

+% \section{The \Lpack{combine} class code} \label{sec:code}
+%
+% There are various difficulties to be overcome by the
+% \Lpack{combine} code, some seemingly inherent in \TeX{} itself and
+% others by the \LaTeX{} kernel code. These include, but are not limited to:
+% \begin{itemize}
+% \item TeX{} was not designed for processing multiple documents.
+% \item There can only be one |\documentclass| command within
+% a document.
+% \item There are many \LaTeX{} commands that can only be used in
+% the preamble, and the preamble is closed by the (first) |\begin{document}|.
+% \item There is a single global page number, which may be reset to one
+% at any point in any document. If this occurs in an imported document
+% then the page numbering for the main document is similarly reset.
+% \item |\label|s are global in nature, and with multiple imported
+% documents there are likely to be labels with the same name in two
+% or more of these.
+% \item Many of the kernel (and standard classes) commands use
+% the page number; sometimes the use is buried at the end of a chain
+% of macros.
+% \end{itemize}
+%
+% A design goal for \Lpack{combine} is that virtually any kind
+% of document should be importable and should be processible without
+% have to make any changes to it. To completely satisfy this would
+% require a rewrite of much of the \LaTeX{} kernel, which is out
+% of the question. Of necessity some changes have had to be made but
+% these have been limited as far as possible. I think that a collection
+% that consists of documents that are all of the same class should
+% process without interruption.
+%
+% When there are mixed classes, \LaTeX{}
+% reads in the code for each class. An example is importing a \Lpack{letter}
+% class document into an \Lpack{article} class collection.
+% If the same command is defined
+% by |\newcommand| in two or more of these classes, then \LaTeX{}
+% complains and I see no way of getting around this without rewriting
+% all the classes and kernel to use |\def| instead of |\newcommand|.
+% In any event, if this happens, try responding to the errors by hitting
+% `q' to put \LaTeX{} into a batch mode. The typeset result may be useable.
+%
+% To try and avoid name clashes, all the internal commands include
+% the string |c@l|.

+% \section{Kernel modifications (and potential additions)}
+%
+% Much of the class code consists of new versions of \LaTeX{} kernel commands.

+% imported documents.

+% \begin{macro}{\c@lenvironment}

+% \begin{macro}{\c@lthrowenv}
+% To stop \LaTeX{} whining when multiple classes are read which happen
+% to define commands (via |\newcommand|) or environments
+% (via |\newenvironment|) that have the same names, we need to be able
+% to make \LaTeX{} use |\providecommand| and |\provideenvironment|
+% instead. Unfortunately the kernel does not provide a |\provideenvironment|
+% command, so here is one based on the code in the \Lpack{makecmds} package.
+% \begin{macrocode}

+% This package calls the \Lpack{natbib} package~\cite{NATBIB}

+% and all options are passed to it to deal with.

+%
+% For multiple bibliographies (|\c@lonebibfalse|)
+% the change consists of replacing

+% naming of citation labels in the \file{.aux} files by the form
+% used by the \Lpack{combine} class. That is, the |b@| in each
+% code fragment like |b@#...| or |b@\...| is replaced by
+% |B?\jobname?@...|.
+%
+% For a single main bibliography |\c@lonebibtrue|, implementation is much
+% easier, merely ensuring that the stuff gets written to the main
+% *.aux file.
