+% \section{The {\sc docstrip} modules}
+%
+% The following modules are used in the implementation to direct
+% {\sc docstrip} in generating the external files:
+% \begin{center}
+% \begin{tabular}{ll}
+% class & produce the document class\\
+% type1 & produce the `1' variants of the classes\\
+% type3 & produce the `3' variants of the classes\\
+% driver & produce a documentation driver file \\
+% \end{tabular}
+% \end{center}
+%
+% \section{Initial Code}
+%
+% In this part we define a few commands that are used later on.
+%
+% \begin{macro}{\@ptsize}
+% This control sequence is used to store the second digit of the
+% pointsize we are typesetting in. So, normally, it's value is one
+% of 0, 1 or 2.
+% \begin{macrocode}
+%<*class>
+\newcommand\@ptsize{}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\if@restonecol}
+% When the document has to printed in two columns, we sometimes
+% have to temporarily switch to one column. This switch is used to
+% remember to switch back.
+% \begin{macrocode}
+\newif\if@restonecol
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\if@titlepage}
+% A switch to indicate if a titlepage has to be produced.
+% \begin{macrocode}
+\newif\if@titlepage
+\@titlepagetrue
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\if@openright}
+% A switch to indicate if chapters must start on a right-hand page.
+% The default for the report class is no; for the book class it's
+% yes.
+% \begin{macrocode}
+\newif\if@openright
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\if@openbib}
+% A switch to indicate if the bibliography has to be produced in
+% the ``open'' format. The default is to use a ``closed'' format.
+% \begin{macrocode}
+\newif\if@openbib
+\@openbibfalse
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\if@oldtoc}
+% A switch to indicate if `old' layout of the table of contents
+% should be produced. These document classes normally produce a
+% table of contents that looks quite different from what the
+% standard classes produce.
+% \begin{macrocode}
+\newif\if@oldtoc
+\@oldtocfalse
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\if@allcaps}
+% By default the text on the titlepage is set in capital letters.
+% This can be disabled by the option \Lopt{mctitle}, which sets the
+% switch |\if@allcaps| to false.
+% \begin{macrocode}
+\newif\if@allcaps
+% \end{macro}
+%
+% \begin{macro}{\if@titlecentered}
+% In the document classes \file{wijzer3} the
+% default placement of the title that is produced by |\maketitle|
+% is flushleft. This can be changed by the switch
+% |\if@titlecentered|.
+% \begin{macrocode}
+%<+type3>\newif\if@titlecentered
+%<+type3>\@titlecenteredfalse
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\if@revlabel}
+% These document classes need to be able to change the positioning
+% of the label in labeled lists. This switch is used for that
+% purpose.
+% \begin{macrocode}
+\newif\if@revlabel
+% \end{macrocode}
+% \end{macro}
+%
+% \section{Declaration of Options}
+%
+%
+% \subsection{Setting Paper Sizes}
+%
+% The variables |\paperwidth| and |\paperheight| should reflect the
+% physical paper size after trimming. For desk printer output this
+% is usually the real paper size since there is no post-processing.
+% Classes for real book production will probably add other paper
+% sizes and additionally the production of crop marks for trimming.
+% \begin{macrocode}
+\DeclareOption{a4paper}
+ {\setlength\paperheight {297mm}%
+ \setlength\paperwidth {210mm}}
+\DeclareOption{a5paper}
+ {\setlength\paperheight {210mm}%
+ \setlength\paperwidth {148mm}}
+\DeclareOption{b5paper}
+ {\setlength\paperheight {250mm}%
+ \setlength\paperwidth {176mm}}
+\DeclareOption{letterpaper}
+ {\setlength\paperheight {11in}%
+ \setlength\paperwidth {8.5in}}
+\DeclareOption{legalpaper}
+ {\setlength\paperheight {14in}%
+ \setlength\paperwidth {8.5in}}
+\DeclareOption{executivepaper}
+ {\setlength\paperheight {10.5in}%
+ \setlength\paperwidth {7.25in}}
+% \end{macrocode}
+%
+% The option \Lopt{landscape} switches the values of |\paperheight|
+% and |\paperwidth|, assuming the dimensions wer given for portrait
+% paper.
+% \begin{macrocode}
+\DeclareOption{landscape}
+ {\setlength\@tempdima {\paperheight}%
+ \setlength\paperheight {\paperwidth}%
+ \setlength\paperwidth {\@tempdima}}
+% \end{macrocode}
+%
+% \subsection{Choosing the type size}
+%
+% The type size options are handled by defining |\@ptsize| to contain
+% the last digit of the size in question and branching on |\ifcase|
+% statements. This is done for historical reasons to stay compatible
+% with other packages that use the |\@ptsize| variable to select
+% special actions. It makes the declarations of size options less
+% than 10pt difficult, although one can probably use \texttt{9}
+% and \texttt{8} assuming that a class won't define both
+% \Lopt{8pt} and \Lopt{18pt} options.
+%
+% \begin{macrocode}
+\DeclareOption{10pt}{\renewcommand\@ptsize{0}}
+\DeclareOption{11pt}{\renewcommand\@ptsize{1}}
+\DeclareOption{12pt}{\renewcommand\@ptsize{2}}
+% \end{macrocode}
+%
+%
+% \subsection{Two-side or one-side printing}
+%
+% For two-sided printing we use the switch |\if@twoside|. In
+% addition we have to set the |\if@mparswitch| to get any margin
+% paragraphs into the outside margin.
+% \begin{macrocode}
+\DeclareOption{oneside}{\@twosidefalse \@mparswitchfalse}
+\DeclareOption{twoside}{\@twosidetrue \@mparswitchtrue}
+% \end{macrocode}
+%
+%
+% \subsection{Draft option}
+%
+% If the user requests \Lopt{draft} we show any overfull boxes.
+% We could probably add some more interesting stuff to this option.
+% \begin{macrocode}
+\DeclareOption{draft}{\setlength\overfullrule{5pt}}
+\DeclareOption{final}{\setlength\overfullrule{0pt}}
+% \end{macrocode}
+%
+% \subsection{Titlepage option}
+% An article usually has no separate titlepage, but the user can
+% request one.
+% \begin{macrocode}
+\DeclareOption{titlepage}{\@titlepagetrue}
+\DeclareOption{notitlepage}{\@titlepagefalse}
+% \end{macrocode}
+%
+% \subsection{openright option}
+% This option determines whether or not a chapter must start on
+% a right-hand page
+% request one.
+% \begin{macrocode}
+\DeclareOption{openright}{\@openrighttrue}
+\DeclareOption{openany}{\@openrightfalse}
+% \end{macrocode}
+%
+% For these document classes there used to be a file
+% \file{voorwerk.sty} which was a replacement for
+% \file{titlepag.sty}. Therefore we also have the option
+% \Lopt{voorwerk}.
+% \begin{macrocode}
+\DeclareOption{voorwerk}{\@titlepagetrue}
+\DeclareOption{geenvoorwerk}{\@titlepagefalse}
+% \end{macrocode}
+%
+%
+% \subsection{Table of contents formatting}
+%
+% This document class uses a new layout for the table of contents,
+% but in order to maintain compatibility with the standard \LaTeXe
+% document classes we supply an extra option: \Lopt{oldtoc}. If
+% this option is specified the switch |\if@oldtoc| will be set
+% true.
+% \begin{macrocode}
+\DeclareOption{oldtoc}{\@oldtoctrue}
+% \end{macrocode}
+%
+% \subsection{Formatting of the title}
+%
+% The option \Lopt{titlecentered} changes the behaviour of the
+% |\maketitle| command. It then produces a title like it does for
+% the \file{artikel1} document class.
+% \begin{macrocode}
+%<+type3>\DeclareOption{titlecentered}{\@titlecenteredtrue}
+% \end{macrocode}
+%
+% In this document class the titlepage uses all capital
+% letters. The option \Lopt{mctitle} (for `mixed case') prevents
+% this.
+% \begin{macrocode}
+\DeclareOption{mctitle}{\@allcapsfalse}
+\DeclareOption{uctitle}{\@allcapstrue}
+% \end{macrocode}
+%
+% \subsection{Twocolumn printing}
+%
+% Two-column and one-column printing is again realized via a switch.
+% \begin{macrocode}
+\DeclareOption{onecolumn}{\@twocolumnfalse}
+\DeclareOption{twocolumn}{\@twocolumntrue}
+% \end{macrocode}
+%
+% \subsection{Equation numbering on the left}
+%
+% The option \Lopt{leqno} can be used to get the equation numbers
+% on the left side of the equation.
+% \begin{macrocode}
+\DeclareOption{leqno}{\input{leqno.clo}}
+% \end{macrocode}
+%
+% \subsection{Flush left displays}
+%
+% The option \Lopt{fleqn} redefines the displayed math environmens
+% in such a way that they come out flush left, with an indentation
+% of |\mathindent| from the prevailing left margin.
+% \begin{macrocode}
+\DeclareOption{fleqn}{\input{fleqn.clo}}
+% \end{macrocode}
+%
+% \subsection{Open bibliography}
+%
+% The option \Lopt{openbib} produces the ``open'' bibliography
+% style, in which each block starts on a new line, and succeeding
+% lines in a block are indented by |\bibindent|.
+% \begin{macrocode}
+\DeclareOption{openbib}{\@openbibtrue}
+% \end{macrocode}
+%
+%
+% \section{Executing Options}
+%
+% Here we execute the default options to initialize certain
+% variables.
+% \begin{macrocode}
+\ExecuteOptions{a4paper,10pt,oneside,onecolumn,final,uctitle,openany}
+% \end{macrocode}
+%
+% The |\ProcessOptions| command causes the execution of the code
+% for every option \Lopt{FOO}
+% which is declared and for which the user typed
+% the \Lopt{FOO} option in his
+% |\documentclass| command. For every option \Lopt{BAR} he typed,
+% which is not declared, the option is assumed to be a global option.
+% All options will be passed as document options to any
+% |\usepackage| command in the document preamble.
+% \begin{macrocode}
+\ProcessOptions
+% \end{macrocode}
+% Now that all the options have been executed we can load the
+% chosen class option file that contains all size dependent code.
+% \begin{macrocode}
+\input{ntg1\@ptsize.clo}
+% \end{macrocode}
+%
+% \section{Loading Packages}
+%
+% These class files do not load additional packages.
+%
+%
+% \section{Document Layout}
+% \label{sec:maincode}
+%
+% In this section we are finally dealing with the nasty typographical
+% details.
+%
+% \subsection{Paragraphing}
+%
+% \begin{macro}{\lineskip}
+% \begin{macro}{\normallineskip}
+% These parameters control \TeX's behaviour when two lines tend to
+% come too close together.
+% \begin{macrocode}
+\setlength\lineskip{1\p@}
+\setlength\normallineskip{1\p@}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\baselinestretch}
+% This is used as a multiplier for |\baselineskip|. The default is
+% to {\em not\/} stretch the baselines.
+% \begin{macrocode}
+\renewcommand\baselinestretch{}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\unitindent}
+% These document classes all use a single dimension for a number of
+% layout parameters:
+% \begin{itemize}
+% \item the label width in section heading,
+% \item the |\parindent|
+% \item the footnote label indent (= half |\unitindent|)
+% \item listindent on the first level
+% \end{itemize}
+% \begin{macrocode}
+\newdimen\unitindent
+% \end{macrocode}
+% The default setting accomodates three levels of single digit
+% section numbering.
+% \begin{macrocode}
+{\setbox0\hbox{\normalsize\rmfamily 2.2.2\hskip.5em}
+ \global\unitindent=\wd0}
+% \end{macrocode}
+%
+% \begin{macro}{\othermargin}
+% Other indentations are maximal label width plus white space.
+% \begin{macrocode}
+\newdimen\othermargin
+{\setbox0\hbox{\normalsize (m)\hskip.6em}\global\othermargin=\wd0}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{if@needwriteindent}
+% If this is not enough, a new width is calculated, set, and the
+% file{.aux} file contains an instruction that will set
+% |\unitindent| on the next run.
+%
+% For this we need a switch
+% \begin{macrocode}
+\newif\if@needwriteindent
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@indentset}
+% And a command that sets the various parameters.
+% \begin{macrocode}
+\newcommand\@indentset{%
+%<-type3> \global\parindent=\unitindent
+ \global\leftmargini=\unitindent
+ \global\@needwriteindenttrue}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@writeindent}
+% The |\end{document}| command will call |\@writeindent| to write
+% the final width of |\unitindent| on the \file{.aux} file. Also a
+% command is written to set |\unitindent|. To be compatible with
+% other document classes a check is written to the \file{.aux} file
+% for the existence of |\unitindent|. This prevents nasty errors
+% when another document class is used.
+% \begin{macrocode}
+\newcommand\@writeindent[1]{\immediate\write\@mainaux
+ {\string\@ifundefined{unitindent}{\string\newdimen\string\unitindent
+ \let\string\@indentset\relax}{}}
+ \immediate\write\@mainaux{\global\string\unitindent=#1\string\relax
+ \string\@indentset \string\relax}}
+% \end{macrocode}
+% \end{macro}
+%
+% We need to use the hook into |\end{document}| to write the final
+% value of |\unitindent| om the file{.aux} file for the next run.
+% \begin{macrocode}
+\AtEndDocument{%
+ \if@filesw
+ \if@needwriteindent
+ \@writeindent{\the\unitindent}
+ \fi
+ \fi}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\parskip}
+% \begin{macro}{\parindent}
+% |\parskip| gives extra vertical space between paragraphs and
+% |\parindent| is the width of the paragraph indentation. The value
+% of |\parindent| depends on whether we are in two column mode.
+% \begin{macrocode}
+%<*type1>
+\setlength\parskip{0\p@}
+\setlength\parindent{\unitindent}
+%</type1>
+%<*type3>
+\setlength\parskip{.5\baselineskip \@plus .1\baselineskip
+ \@minus .1\baselineskip}
+\setlength\parindent{\z@}
+%</type3>
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\@lowpenalty}
+% \begin{macro}{\@medpenalty}
+% \begin{macro}{\@highpenalty}%
+% The commands |\nopagebreak| and |\nolinebreak| put in penalties
+% to discourage these breaks at the point they are put in.
+% They use |\@lowpenalty|, |\@medpenalty| or |\@highpenalty|,
+% dependent on their argument.
+% \begin{macrocode}
+\@lowpenalty 51
+\@medpenalty 151
+\@highpenalty 301
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\clubpenalty}
+% \begin{macro}{\widowpenalty}
+% These penalties are use to discourrage club and widow lines.
+% Because we use their default values we only show them here,
+% commented out.
+% \begin{macrocode}
+% \clubpenalty 150
+% \widowpenalty 150
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\displaywidowpenalty}
+% \begin{macro}{\predisplaypenalty}
+% \begin{macro}{\postdisplaypenalty}
+% Discourrage (but not so much) widows in front of a math display
+% and forbid breaking directly in front of a display. Allow break
+% after a display without a penalty. Again the default values are
+% used, therefore we only show them here.
+% \begin{macrocode}
+% \displaywidowpenalty 50
+% \predisplaypenalty 10000
+% \postdisplaypenalty 0
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\interlinepenalty}
+% Allow the breaking of a page in the middle of a paragraph.
+% \begin{macrocode}
+% \interlinepenalty 0
+% \end{macrocode}
+% \end{macro}
+%
+%
+% \begin{macro}{\brokenpenalty}
+% We allow the breaking of a page after a hyphenated line.
+% \begin{macrocode}
+% \brokenpenalty 0
+% \end{macrocode}
+% \end{macro}
+%
+% \subsubsection{Float placement parameters}
+%
+% All float parameters are given default values in the \LaTeXe{}
+% kernel. For this reason counters only need to be set with
+% |\setcounter| and other parameters are set using |\renewcommand|.
+%
+% \paragraph{Limits for the placement of floating objects}
+%
+% \begin{macro}{\c@topnumber}
+% The \Lcount{topnumber} counter holds the maximum number of
+% floats that can appear on the top of a text page.
+% \begin{macrocode}
+\setcounter{topnumber}{2}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\topfraction}
+% This indicates the maximum part of a text page that can be
+% occupied by floats at the top.
+% \begin{macrocode}
+\renewcommand\topfraction{.7}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\c@bottomnumber}
+% The \Lcount{bottomnumber} counter holds the maximum number of
+% floats that can appear on the bottom of a text page.
+% \begin{macrocode}
+\setcounter{bottomnumber}{1}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\bottomfraction}
+% This indicates the maximum part of a text page that can be
+% occupied by floats at the bottom.
+% \begin{macrocode}
+\renewcommand\bottomfraction{.3}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\c@totalnumber}
+% This indicates the maximum number of floats that can appear on
+% any text page.
+% \begin{macrocode}
+\setcounter{totalnumber}{3}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\textfraction}
+% This indicates the minimum part of a text page that has to be
+% occupied by text.
+% \begin{macrocode}
+\renewcommand\textfraction{.2}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\floatpagefraction}
+% This indicates the minimum part of a page that has to be
+% occupied by floating objects before a `float page' is produced.
+% \begin{macrocode}
+\renewcommand\floatpagefraction{.5}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\c@dbltopnumber}
+% The \Lcount{dbltopnumber} counter holds the maximum number of
+% two column floats that can appear on the top of a two column text
+% page.
+% \begin{macrocode}
+\setcounter{dbltopnumber}{2}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\dbltopfraction}
+% This indicates the maximum part of a two column text page that
+% can be occupied by two column floats at the top.
+% \begin{macrocode}
+\renewcommand\dbltopfraction{.7}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\dblfloatpagefraction}
+% This indicates the minimum part of a page that has to be
+% occupied by two column wide floating objects before a `float
+% page' is produced.
+% \begin{macrocode}
+\renewcommand\dblfloatpagefraction{.5}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsection{Page Styles}
+%
+% The page style \pstyle{foo} is defined by defining the command
+% |\ps@foo|. This command should make only local definitions.
+% There should be no stray spaces in the definition, since they
+% could lead to mysterious extra spaces in the output (well, that's
+% something that should be always avoided).
+%
+% \begin{macro}{\@evenhead}
+% \begin{macro}{\@oddhead}
+% \begin{macro}{\@evenfoot}
+% \begin{macro}{\@oddfoot}
+% The |\ps@...| command defines the macros |\@oddhead|,
+% |\@oddfoot|, |\@evenhead|, and |\@evenfoot| to define the running
+% heads and feet---e.g., |\@oddhead| is the macro to produce the
+% contents of the heading box for odd-numbered pages. It is called
+% inside an |\hbox| of width |\textwidth|.
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\thispagestyle}
+% Several commands (|\index|, |\maketitle|) give a
+% |\thispagestyle{plain}| command, which will overrule a
+% |\pagestyle{empty}| command. This situation is almost always
+% unwanted. Therefore we provide a more careful definition.
+%
+% First save the original definition.
+% \begin{macrocode}
+\let\Thispagestyle\thispagestyle
+% \end{macrocode}
+% Then we provide the new definition, for which we must also adapt
+% |\pagestyle| a little.
+% \begin{macrocode}
+\newcommand\@emptypagestyle{empty}
+\renewcommand\pagestyle[1]{\@nameuse{ps@#1}\def\@currentpagestyle{#1}}
+\renewcommand\thispagestyle[1]{%

+%
+% \subsubsection{Marking conventions}
+%
+% To make headings determined by the sectioning commands, the page
+% style defines the commands |\chaptermark|, |\sectionmark|,
+% \ldots,\\
+% where |\chaptermark{|\meta{TEXT}|}| is called by
+% |\chapter| to set a mark, and so on.
+%
+% The |\...mark| commands and the |\...head| macros are defined
+% with the help of the following macros. (All the |\...mark|
+% commands should be initialized to no-ops.)
+%
+% \LaTeX{} extends \TeX's |\mark| facility by producing two kinds
+% of marks, a `left' and a `right' mark, using the following
+% commands:
+% \begin{flushleft}
+% |\markboth{|\meta{LEFT}|}{|\meta{RIGHT}|}|: Adds both marks.
+%
+% |\markright{|\meta{RIGHT}|}|: Adds a `right' mark.
+%
+% |\leftmark|: Used in the |\@oddhead|, |\@oddfoot|, |\@evenhead|
+% or |\@evenfoot| macros, it gets the current `left'
+% mark. |\leftmark| works like \TeX's |\botmark|
+% command.
+%
+% |\rightmark|: Used in the |\@oddhead|, |\@oddfoot|, |\@evenhead|
+% or |\@evenfoot| macros, it gets the current
+% `right' mark. |\rightmark| works like \TeX's
+% |\firstmark| command.
+% \end{flushleft}
+%
+% The marking commands work reasonably well for right marks
+% `numbered within' left marks--e.g., the left mark is changed by a
+% |\chapter| command and the right mark is changed by a |\section|
+% command. However, it does produce somewhat anomalous results if
+% two |\markboth|'s occur on the same page.
+%
+%
+% Commands like |\tableofcontents| that should set the marks in some
+% page styles use a |\@mkboth| command, which is |\let| by the
+% pagestyle command (|\ps@...|) to |\markboth| for setting the
+% heading or to |\@gobbletwo| to do nothing.
+%
+%
+% \begin{macrocode}
+% %%%\mark{{}{}} % Initializes TeX's marks <--- can vanish
+% \end{macrocode}
+%
+% \subsubsection{Defining the page styles}
+% \label{sec:pagestyle}
+%
+% The pagestyle \pstyle{empty} is defined in \file{latex.dtx}, but
+% the pagestyle \pstyle{plain} is slightly altered here. The
+% difference is that the page numbers are set flush right in
+% onesided and flush left and right in the twosided style.
+%
+% \begin{macro}{\ps@plain}
+%
+% \begin{macrocode}
+\renewcommand\ps@plain{%
+% \end{macrocode}
+% The running head are empty in this pagestyle, the page number
+% appears in the running foot.
+% \begin{macrocode}
+ \let\@oddhead\@empty\let\@evenhead\@empty
+ \def\@oddfoot{\hfil\PageFont\thepage}%
+ \if@twoside
+ \def\@evenfoot{\PageFont\thepage\hfil}%
+ \else
+ \let\@evenfoot\@oddfoot
+ \fi
+% \end{macrocode}
+% Because the running heads should be empty we |let| |\@mkboth| to
+% |\@gobbletwo|, thus disabling the mark commands.
+% \begin{macrocode}
+ \let\@mkboth\@gobbletwo}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\ps@headings}
+% The definition of the page style \pstyle{headings} has to be
+% different for two sided printing than it is for one sided
+% printing.
+%
+% \begin{macrocode}
+\if@twoside
+ \def\ps@headings{%
+% \end{macrocode}
+% The running feet are empty in this page style, the running head
+% contains the page number and one of the marks.
+% \begin{macrocode}
+ \let\@oddfoot\@empty\let\@evenfoot\@empty
+ \def\@evenhead{{\PageFont\thepage}\hfil\MarkFont\leftmark}%
+ \def\@oddhead{{\MarkFont\rightmark}\hfil\PageFont\thepage}%
+% \end{macrocode}
+%
+% When using this page style, the contents of the running head is
+% determined by the chapter and section titles. So we |\let|
+% |\@mkboth| to |\markboth|.
+% \begin{macrocode}
+ \let\@mkboth\markboth
+% \end{macrocode}
+%
+% In thisdocument class we use the |\chaptermark|
+% and |\sectionmark| macros to fill the running heads.
+%
+% Note the use of |##1| for the parameter of the |\chaptermark|
+% command, which will be defined when |\ps@headings| is executed.
+%
+% \begin{macrocode}
+ \def\chaptermark##1{%
+ \markboth {\uppercase{\ifnum \c@secnumdepth >\m@ne
+ \@chapapp\ \thechapter. \ \fi
+ ##1}}{}}%
+ \def\sectionmark##1{%
+ \markright {\uppercase{\ifnum \c@secnumdepth >\z@
+ \thesection. \ \fi
+ ##1}}}}
+% \end{macrocode}
+%
+% The definition of |\ps@headings| for one sided printing can be
+% much simpler, because we treat even and odd pages the same.
+% Therefore we don't need to define |\@even...|.
+% \begin{macrocode}
+\else
+ \def\ps@headings{%
+ \let\@oddfoot\@empty
+ \def\@oddhead{{\MarkFont\rightmark}\hfil\PageFont\thepage}%
+ \let\@mkboth\markboth
+% \end{macrocode}
+% We use |\markright| now instead of |\markboth| as we did for two
+% sided printing.
+% \begin{macrocode}
+ \def\chaptermark##1{%
+ \markright {\uppercase{\ifnum \c@secnumdepth >\m@ne
+ \@chapapp\ \thechapter. \ \fi
+ ##1}}}}
+\fi
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\ps@myheadings}
+% The definition of the page style \pstyle{myheadings} is fairly
+% simple because the user determines the contents of the running
+% head himself by using the |\markboth| and |\markright| commands.
+%
+% \begin{macrocode}
+\def\ps@myheadings{%
+ \let\@oddfoot\@empty\let\@evenfoot\@empty
+ \def\@evenhead{{\PageFont\thepage}\hfil\MarkFont\leftmark}%
+ \def\@oddhead{{\MarkFont\rightmark}\hfil\PageFont\thepage}%
+% \end{macrocode}
+%
+% We have to make sure that the marking commands that are used by
+% the chapter and section headings are disabled. We do this
+% |\let|ting them to a macro that gobbles its argument(s).
+% \begin{macrocode}
+ \let\@mkboth\@gobbletwo
+ \let\chaptermark\@gobble
+ \let\sectionmark\@gobble
+ }
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\PageFont}

+% \section{Document Markup}
+%
+% \subsection{The title}
+%
+% \begin{macro}{\title}
+% \begin{macro}{\author}
+% \begin{macro}{\date}
+% These three macros are provided by \file{latex.dtx} to provide
+% information about the title, author(s) and date of the document.
+% The information is stored away in internal control sequences.
+% It is the task of the |\maketitle| command to use the
+% information provided. The definitions of these macros are shown
+% here for information.
+% \begin{macrocode}
+% \newcommand\title[1]{\gdef\@title{#1}}
+% \newcommand\author[1]{\gdef\@author{#1}}
+% \newcommand\date[1]{\gdef\@date{#1}}
+% \end{macrocode}
+% The |\date| macro gets today's date by default.
+% \begin{macrocode}
+% \gdef\@date{\today}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\TitleFont}
+% This selects the font to use in the title of the document.
+% \begin{macrocode}
+\newcommand\TitleFont{\bfseries}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\maketitle}
+% The definition of |\maketitle| depends on whether a seperate
+% title page is made. This is the default for this document class.
+% Note that the title, author and date information is printed in
+% capital letters by default. This can be changed by the option
+% \Lopt{mctitle}.
+%
+% When we are making a title page, we locally redefine
+% |\footnotesize| and |\footnoterule| to change the appearance of
+% the footnotes that are produced by the |\thanks| command.
+% \begin{macrocode}
+\renewcommand\TitleFont{\rmfamily}
+\newcommand\maketitle{%
+ \begin{titlepage}%
+ \let\footnotesize\small
+ \let\footnoterule\relax
+% \end{macrocode}
+% Footnotes on the titlepage, generated by the use of |\thanks|,
+% use symbols in these document classes.
+% \begin{macrocode}
+ \long\def\@makefntext##1{\parindent\z@
+ \def\labelitemi{--}\@revlabeltrue
+ \leavevmode$\m@th^{\@thefnmark}$\kern1em\relax ##1}
+ \renewcommand\thefootnote{\fnsymbol{footnote}}%
+% \end{macrocode}
+% We center the entire title vertically; the centering is set off a
+% little by adding a |\vskip|. In compatibility mode the pagenumber
+% is set to 0 to keep the behaviour of \LaTeX\ 2.09 style files
+% \begin{macrocode}
+ \if@compatibility\setcounter{page}{0}\fi
+ \null\vfil
+ \vskip 60\p@
+% \end{macrocode}
+% Then we set the title, in a |\LARGE| font; leave a little space
+% and set the author(s) in a |\large| font. We do this inside a
+% tabular environment to get them in a single column.
+% Before the date we leave a little whitespace again.
+% \begin{macrocode}
+ \begin{center}%
+ \TitleFont
+ {\LARGE \def\\{\penalty -\@M}
+ \if@allcaps
+ \expandafter\uc@nothanks\@title\thanks\relax
+ \else
+ \@title
+ \fi\par}%
+ \vskip 3em%
+ {\large
+ \lineskip .75em \parindent\z@
+ \begin{tabular}[t]{c}%
+ \if@allcaps
+ \expandafter\uc@authornothanks\@author\and\relax
+ \else
+ \@author
+ \fi
+ \end{tabular}\par}%
+ \vskip 1.5em%
+ {\large
+ \if@allcaps
+ \uppercase\expandafter{\@date}%
+ \else
+ \@date
+ \fi\par}%
+ \end{center}\par
+% \end{macrocode}
+% Then we call |\@thanks| to print the information that goes into
+% the footnote and finish the page.
+% \begin{macrocode}
+ \@thanks
+ \vfil\null
+ \end{titlepage}%
+% \end{macrocode}
+% We reset the \Lcount{footnote} counter, disable |\thanks| and
+% |\maketitle| and save some storage space by emptying the internal
+% information macros.
+% \begin{macrocode}
+ \setcounter{footnote}{0}%
+ \let\thanks\relax\let\maketitle\relax
+ \gdef\@thanks{}\gdef\@author{}\gdef\@title{}}
+% \end{macrocode}
+%
+% We want to have the title, author and date information in
+% uppercase, but we have to be very carefull not to put too much
+% text in uppercase. The macros that perform the filtering of texts
+% that shouldn't be in uppercase were developped with th help of
+% Howard Trickey.
+%
+% \begin{macro}{\uc@nothanks}
+% This macro takes all the text up to the first use of |\thanks|
+% and passes it to |\uppercase|. The use of |\futurelet| will store
+% the token \emph{after} the |\thanks| in |\@tempa|. The macro
+% |\u@tx| uses that information to determine what to do next.
+% \begin{macrocode}
+\def\uc@nothanks#1\thanks{\uppercase{#1}\futurelet\@tempa\uc@tx}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\uc@authornothanks}
+% A document can have more than one author. Usually they are
+% seperated with |\and|. For each author a footnote --using
+% |\thanks| can be present. Therefore this macro takes all the text
+% up to the first use of |\and|, thus picking up all the
+% information for one author. This is than passsed to
+% |\uc@nothanks|, which checks for the presence of |\thanks|. For
+% this to work the argument of |\uc@nothanks| has to be delimited
+% by |\thanks\relax|.
+% \begin{macrocode}
+\def\uc@authornothanks#1\and{\uc@nothanks#1\thanks\relax
+% \end{macrocode}
+% Then we have to check whether the |\and| we ound earlier was put
+% in by the user, in which case information for another user will
+% follow, or by the call from another macro, in which case the
+% |\and| will be followed by a |\relax| token. The |\futurelet|
+% contstruct stores the first token \emph{after} the |\and| in
+% |\@tempa| to be inspected by |\u@ax|.
+% \begin{macrocode}
+ \futurelet\@tempa\uc@ax}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\uc@ax}
+% When |\@tempa| contains a |\relax| token nothing needs to be
+% done, when it doesn't we put in a linebreak |\\| the word `and'
+% (stored in |\andname| so that this control sequence can be
+% redeined for other languages), another linebreak and we call
+% |\uc@authornothanks| to continue processing. The |\expandafter|
+% lets \TeX\ see the |\fi| first.
+% \begin{macrocode}
+\def\uc@ax{%
+ \ifx\@tempa\relax
+ \else
+ \\ \andname \\ \expandafter\uc@authornothanks
+ \fi}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\uc@tx}
+% This macro simply checks whether |\@tempa| contains a |\relax|
+% token. When it doesn't further processing is performed by
+% |\u@ty|.
+% \begin{macrocode}
+\def\uc@tx{\ifx\@tempa\relax
+ \else \expandafter\uc@ty \fi}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\uc@ty}
+% The macro |\uc@ty| gets executed when the |\thanks| that
+% delimited text earlier on in the processing had a real argument.
+% In that case it was a |\thanks| put in by the user, \emph{not} by
+% these macros. Therefore the argument is now passed to |\thanks|
+% and processing continues by calling |\uc@nothanks|.
+% \begin{macrocode}
+\def\uc@ty#1{\thanks{#1}\uc@nothanks}
+% \end{macrocode}
+% \end{macro}
+%
+% When the title is not on a page of its own, the layout of the
+% title is a little different. We use symbols to mark the footnotes
+% and we have to deal with two column documents.
+%
+% Therefore we first start a new group to keep changes local. Then
+% we redefine |\thefootnote| to use |\fnsymbol|; and change
+% |\@makefnmark| so that footnotemarks have zero width (to make the
+% centering of the author names look better). We also want raised
+% footnotemarkers in the footnotes here.
+% \begin{macrocode}
+\else
+\newcommand\maketitle{\par
+ \begingroup
+ \renewcommand\thefootnote{\fnsymbol{footnote}}%
+ \def\@makefnmark{\hbox to\z@{$\m@th^{\@thefnmark}$\hss}}%
+ \def\@makefntext{\@xmakefntext{$\m@th^{\@thefnmark}$}}%
+% \end{macrocode}
+% If this is a twocolumn document we start a new page in twocolumn
+% mode, with the title set to the full width of the text. The
+% actual printing of the title information is left to
+% |\@maketitle|.
+% \begin{macrocode}
+ \if@twocolumn
+ \ifnum \col@number=\@ne
+ \@maketitle
+ \else
+ \twocolumn[\@maketitle]%
+ \fi
+ \else
+% \end{macrocode}
+% When this is not a twocolumn document we just start a new page,
+% prevent floating objects from appearing on the top of this page
+% and print the title information.
+% \begin{macrocode}
+ \newpage
+ \global\@topnum\z@
+ \@maketitle
+ \fi
+% \end{macrocode}
+% This page gets a \pstyle{plain} layout. We call |\@thanks| to
+% produce the footnotes.
+% \begin{macrocode}
+ \thispagestyle{plain}\@thanks
+% \end{macrocode}
+% Now we can close the group, reset the \Lcount{footnote} counter,
+% disable |\thanks|, |\maketitle| and |\@maketitle| and save some
+% storage space by emptying the internal information macros.
+% \begin{macrocode}
+ \endgroup
+ \setcounter{footnote}{0}%

+%
+% \begin{macro}{\@maketitle}
+% This macro takes care of formatting the title information when we

+%
+% We always start a new page, leave some white space and center the

+% \subsection{Chapters and Sections}
+%
+% \subsubsection{Building blocks}
+% The definitions in this part of the class file make use of two
+% macros, |\@startsection| and |\secdef|, which are defined by
+% \file{latex.dtx}. To understand what is going on here, we
+% describe their syntax.
+%
+% The macro |\@startsection| has 6 required arguments, optionally
+% followed by a $*$, an optional argument and a required argument:
+%
+% |\@startsection|\meta{name}\meta{level}\meta{indent}^^A
+% \meta{beforeskip}\meta{afterskip}\meta{style}
+% optional *\\
+% \null\hphantom{\bslash @startsection}^^A
+% |[|\meta{altheading}|]|\meta{heading}
+%
+% It is a generic command to start a section, the arguments have
+% the following meaning:
+%
+% \begin{description}
+% \item[\meta{name}] The name of the user level command, e.g.,
+% `section'.
+% \item[\meta{level}] A number, denoting the depth of the section
+% -- e.g., chapter=1, section = 2, etc. A section number
+% will be printed if and only if \meta{level} $<=$ the value
+% of the \Lcount{secnumdepth} counter.
+% \item[\meta{indent}] The indentation of the heading from the left
+% margin
+% \item[\meta{beforeskip}] The absolute value of this argument
+% gives the skip to leave above the heading. If it is
+% negative, then the paragraph indent of the text following
+% the heading is suppressed.
+% \item[\meta{afterskip}] If positive, this gives the skip to leave
+% below the heading, else it gives the skip to leave to the
+% right of a run-in heading.
+% \item[\meta{style}] Commands to set the style of the heading.
+% \item[$*$] When this is missing the heading is numbered and the
+% corresponding counter is incremented.
+% \item[\meta{altheading}] Gives an alternative heading to use in
+% the table of contents and in the running heads. This should
+% be present when the $*$ form is used.
+% \item[\meta{heading}] The heading of the new section.
+% \end{description}
+% A sectioning command is normally defined to |\@startsection| and
+% its first six arguments.
+%
+% The macro |\secdef| can be used when a sectioning command is
+% defined without using |\@startsection|. It has two arguments:
+%
+% |\secdef|\meta{unstarcmds}\meta{starcmds}
+%
+% \begin{description}
+% \item[\meta{unstarcmds}] Used for the normal form of the
+% sectioning command.
+% \item[\meta{starcmds}] Used for the $*$-form of the
+% sectioning command.
+% \end{description}
+%
+% You can use |\secdef| as follows:
+% \begin{verbatim}
+% \def\chapter { ... \secdef \CMDA \CMDB }
+% \def\CMDA [#1]#2{ ... } % Command to define
+% % \chapter[...]{...}
+% \def\CMDB #1{ ... } % Command to define
+% % \chapter*{...}
+% \end{verbatim}
+%
+% \begin{macro}{\head@style}
+% In the definition of chapter and section commands a number of
+% settings frequently occur. Therefore we store them in a control
+% sequence.
+%
+% Section headings are to be set extremely raggedright, with no
+% hyphenations, not even at explicit hyphens.
+%
+% \begin{macrocode}
+\newcommand\head@style{%
+ \interlinepenalty \@M
+ \hyphenpenalty=\@M \exhyphenpenalty=\@M
+ \rightskip=0cm plus .7\hsize\relax}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@sect}
+% The definition of this macro from \file{latex.dtx} needs to be
+% repeated here because we want to modify its behaviour with
+% respect to:
+% \begin{enumerate}
+% \item the width of the number, which is fixed;
+% \item checking the value of |\unitindent|;
+% \item formatting the section title ragged right;
+% \item changing the argument of |\contentsline|.
+% \end{enumerate}
+% \begin{macrocode}
+\def\@sect#1#2#3#4#5#6[#7]#8{\ifnum #2>\c@secnumdepth
+ \let\@svsec\@empty\else
+ \refstepcounter{#1}%
+% \end{macrocode}
+% The following code (within the group) checks the value of
+% |\unitindent|. If the sectionnumber is wider than |\unitindent|
+% its value is adapted and a flag is set to rememeber to store the
+% new value in the \file{.aux}-file.

+% For any counter \Lcount{CTR}, |\theCTR| is a macro that defines
+% the printed version of counter \Lcount{CTR}. It is defined in
+% terms of the following macros:
+%
+% |\arabic{|\Lcount{COUNTER}|}| prints the value of
+% \Lcount{COUNTER} as an arabic numeral.
+%
+% |\roman{|\Lcount{COUNTER}|}| prints the value of
+% \Lcount{COUNTER} as a lowercase roman numberal.
+%
+% |\Roman{|\Lcount{COUNTER}|}| prints the value of
+% \Lcount{COUNTER} as an uppercase roman numberal.
+%
+% |\alph{|\Lcount{COUNTER}|}| prints the value of \Lcount{COUNTER}
+% as a lowercase letter: $1 =$~a, $2 =$~ b, etc.
+%
+% |\Alph{|\Lcount{COUNTER}|}| prints the value of \Lcount{COUNTER}
+% as an uppercase letter: $1 =$~A, $2 =$~B, etc.

+% |\@chapapp| is initially defined to be `|\chaptername|'. The

+%
+% \subsubsection{Parts}
+%
+% \begin{macro}{\part}
+% The command to start a new part of our document.
+%
+% We start a new (righthand) page and use the \pstyle{empty}.
+% \begin{macrocode}
+\newcommand\part{\cleardoublepage
+ \thispagestyle{empty}%
+% \end{macrocode}
+% When we are making a two column document, this will be a one
+% column page. We use |@tempswa| to remember to switch back to two
+% columns.
+% \begin{macrocode}
+ \if@twocolumn
+ \onecolumn
+ \@tempswatrue
+ \else
+ \@tempswafalse
+ \fi
+% \end{macrocode}
+% We need an empty box to prevent the fil glue from disappearing.
+% \begin{macrocode}
+ \hbox{}\vfil
+% \end{macrocode}
+% Here we use |\secdef| to indicate wwhich commands to use to make
+% the actual heading.
+% \begin{macrocode}
+ \secdef\@part\@spart}
+% \end{macrocode}
+%
+% \begin{macro}{\@part}
+% This macro does the actual formatting of the title of the part.
+%
+% \begin{macro}{\PartFont}
+% The font used to typeset the part is stored in this maro.
+% \begin{macrocode}
+\newcommand\PartFont{\bfseries}
+% \end{macrocode}
+% \end{macro}
+%
+% When \Lcount{secnumdepth} is larger than $-2$ for this document
+% class, we have a numbered part, otherwise it is unnumbered.
+% \begin{macrocode}
+\def\@part[#1]#2{%
+ \ifnum \c@secnumdepth >-2\relax
+ \refstepcounter{part}%
+ \addcontentsline{toc}{part}{\thepart\hspace{1em}\toc@case{#1}}%
+ \else
+ \addcontentsline{toc}{part}{\toc@case{#1}}%
+ \fi
+% \end{macrocode}
+% We empty the mark registers and center the title on the page.
+% Also we prevent breaking between lines and reset the font.
+% \begin{macrocode}
+ \markboth{}{}
+ {\centering
+ \interlinepenalty \@M
+ \reset@font
+% \end{macrocode}
+% When this is a numbered part we have to print the number. We have
+% to expand |\partname| before |\uppercase| is called, therefore we
+% use a temporary control sequence that, when called will execute
+% |\uppercase| on the contents of |\partname|.
+% \begin{macrocode}
+ \ifnum \c@secnumdepth >-2\relax
+ \Large\PartFont
+ \edef\@tempa{\noexpand\uppercase{\partname}}\@tempa~\thepart
+ \par
+% \end{macrocode}
+% We leave some space before we print the title and leave the
+% finishing up to |\@endpart|.
+% \begin{macrocode}
+ \vskip 20\p@
+ \fi
+ \Large \PartFont \uppercase{#2}\par}%
+ \@endpart}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@spart}
+% This macro does the actual formatting of the title of the part
+% when the star form of the user command was used. In this case we
+% {\em never} print a number. Otherwise the formatting is the same.
+%
+% \begin{macrocode}
+\def\@spart#1{%
+ {\centering
+ \interlinepenalty \@M
+ \reset@font
+ \Large \PartFont #1\par}%
+ \@endpart}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@endpart}
+% This macro finishes the part page, for both |\@part| and
+% |\@spart|.
+%
+% First we fill the current page.
+% \begin{macrocode}
+\def\@endpart{\vfil\newpage
+% \end{macrocode}
+% Then, when we are in twosided mode, we produce a completely blank
+% page.
+% \begin{macrocode}
+ \if@twoside
+ \hbox{}%
+ \thispagestyle{empty}%
+ \newpage
+ \fi
+% \end{macrocode}
+% When this was a two column document we have to switch back to two
+% column mode.
+% \begin{macrocode}
+ \if@tempswa
+ \twocolumn
+ \fi}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \subsubsection{Chapters}
+%
+% \begin{macro}{\chapter}
+% A chapter should always start on a new page therefore we start by
+% calling |\clearpage| and setting the pagestyle for this page to
+% \pstyle{plain}.
+% \begin{macrocode}
+\newcommand\chapter{\if@openright\cleardoublepage\else\clearpage\fi
+ \thispagestyle{plain}%
+% \end{macrocode}
+% Then we prevent floats from appearing at the top of this page
+% because it looks weird to see a floating object above a chapter
+% title.
+% \begin{macrocode}
+ \global\@topnum\z@
+% \end{macrocode}
+% Then we suppress the indentation of the first paragraph by
+% setting the switch |\@afterindent| to |false|. We use |\secdef|
+% to specify the macros to use for actually setting the chapter
+% title.
+% \begin{macrocode}
+ \@afterindentfalse
+ \secdef\@chapter\@schapter}
+% \end{macrocode}
+%
+% \begin{macro}{\@chapter}
+% This macro is called when we have a numbered chapter. When
+% \Lcount{secnumdepth} is larger than $-1$ we display the chapter
+% number. We also inform the user that a new chapter is about to be
+% typeset by writing a message to the terminal.
+% \begin{macrocode}
+\def\@chapter[#1]#2{%
+ \ifnum \c@secnumdepth >\m@ne
+ \refstepcounter{chapter}%
+ \typeout{\@chapapp\space\thechapter.}%
+ \addcontentsline{toc}{chapter}%
+ {\protect\numberline{\thechapter}\toc@font0 #1}%
+ \else
+ \addcontentsline{toc}{chapter}{\toc@font0 #1}%
+ \fi
+% \end{macrocode}
+% After having written an entry to the table of contents we store
+% the (alternative) title of this chapter with |\chaptermark| and
+% add some white space to the lists of figures and tables.
+% \begin{macrocode}
+ \chaptermark{#1}%
+ \addtocontents{lof}{\protect\addvspace{10\p@}}%
+ \addtocontents{lot}{\protect\addvspace{10\p@}}%
+% \end{macrocode}
+% Then we call upon |\@makechapterhead| to format the actual
+% chapter title. We have to do this in a special way when we are in
+% twocolumn mode in order to have the chapter title use the entire
+% |\textwidth|. In one column mode we call |\@afterheading| which
+% takes care of suppressing the indentation.
+% \begin{macrocode}
+ \if@twocolumn
+ \@topnewpage[\@makechapterhead{#2}]%
+ \else
+ \@makechapterhead{#2}%
+ \@afterheading
+ \fi}
+% \end{macrocode}
+%
+% \begin{macro}{\ChapFont}
+% The font used to typeset the chapters is stored in this maro.
+% \begin{macrocode}
+\newcommand\ChapFont{\bfseries}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@makechapterhead}
+% The macro above uses |\@makechapterhead|\meta{text} to format the
+% heading of the chapter.
+%
+% We begin by leaving some white space. The we open a group in
+% which we have a paragraph indent of 0pt, and in which we have the
+% text set ragged right. We also reset the font.
+% \begin{macrocode}
+\def\@makechapterhead#1{%
+ \vspace*{50\p@ \@plus 5\p@}%
+ {\setlength\parindent{\z@}%
+ \setlength\parskip {\z@}%
+ \head@style \reset@font
+% \end{macrocode}
+% Then we check whether the number of the chapter has to be printed.
+% If so we leave some whitespace between the chapternumber and its
+% title.
+% \begin{macrocode}
+ \ifnum \c@secnumdepth >\m@ne
+ \Large\ChapFont \@chapapp{} \thechapter
+ \par
+ \vskip 20\p@
+ \fi
+% \end{macrocode}
+% Now we set the title in a large bold font. We prevent a pagebreak
+% at this point and leave some whitespace before the text begins.
+% \begin{macrocode}
+ \Large \ChapFont #1\par
+ \nobreak
+ \vskip 40\p@
+ }}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\@schapter}
+% This macro is called when we have an unnumbered chapter. It is
+% much simpler than |\@chapter| because it only needs to typeset
+% the chapter title.
+% \begin{macrocode}
+\def\@schapter#1{\if@twocolumn
+ \@topnewpage[\@makeschapterhead{#1}]%
+ \else
+ \@makeschapterhead{#1}%
+ \@afterheading
+ \fi}
+% \end{macrocode}
+%
+% \begin{macro}{\@makeschapterhead}
+% The macro above uses |\@makeschapterhead|\meta{text}to format
+% the heading of the chapter. It is similar to |\@makechapterhead|
+% except that it never has to print a chapter number.
+%
+% \begin{macrocode}
+\def\@makeschapterhead#1{%
+ \vspace*{50\p@\@plus 5\p@}%
+ {\setlength\parindent{\z@}%
+ \setlength\parskip{\z@}%
+ \head@style
+ \reset@font
+ \Large \ChapFont #1\par
+ \nobreak
+ \vskip 40\p@
+ }}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+%
+% \subsubsection{Lower level headings}
+%
+% These commands all make use of |\@startsection|.
+% \begin{macro}{\section}
+% This gives a normal heading with white space above the heading
+% (the whitespace below the heading will be generated by the
+% |\parskip| that is inserted at the start of the first paragraph),
+% the title set in |\large\bfseries|, and no indentation on the
+% first paragraph.

+% \subsection{Lists}
+%
+% \subsubsection{General List Parameters}
+%
+% The following commands are used to set the default values for the list
+% environment's parameters. See the \LaTeX{} manual for an explanation
+% of the meanings of the parameters. Defaults for the list
+% environment are set as follows. First, |\rightmargin|,
+% |\listparindent| and |\itemindent| are set to 0pt. Then, for a Kth
+% level list, the command |\@listK| is called, where `K' denotes `i',
+% '`i', ... , `vi'. (I.e., |\@listiii| is called for a third-level
+% list.) By convention, |\@listK| should set |\leftmargin| to
+% |\leftmarginK|.
+%
+% \begin{macro}{\leftmargin}

+% \begin{macro}{\leftmarginii}
+% \begin{macro}{\leftmarginiii}

+%
+% \subsection{Defining new environments}
+%
+% \subsubsection{Abstract}
+%
+% \begin{environment}{abstract}
+% When we are producing a separate titlepage we also put the
+% abstract on a page of its own. It will be centred vertically on
+% the page.
+%
+% \begin{macrocode}
+\if@titlepage
+ \newenvironment{abstract}{%
+ \titlepage
+ \null\vfil
+ \hbox{\SectFont \abstractname}
+ \noindent\ignorespaces}
+ {\par\vfil\null\endtitlepage}
+% \end{macrocode}
+% When we are not making a seperate titlepagewe have to check if we
+% are in twocolumn mode. In that case the abstract is set as a
+% |\section*|, otherwise the abstract is typeset flushleft, an
+% amount |\unitindent| smaller as the normal text.
+% \begin{macrocode}
+\else
+ \newenvironment{abstract}{%
+ \if@twocolumn
+ \section*{\abstractname}%
+ \else
+ \small
+ \bgroup\rightskip=\unitindent
+ \hbox{\SectFont \abstractname}%
+ \noindent\ignorespaces
+% \end{macrocode}
+ \fi}
+% \end{macrocode}
+% Which implies that the definition of |\end{abstract}| is also
+% different.
+% \begin{macrocode}
+ {\if@twocolumn\else\par\egroup\fi}
+\fi
+% \end{macrocode}
+% \end{environment}
+%
+% \subsubsection{Verse}
+%
+% \begin{environment}{verse}
+% The verse environment is defined by making clever use of the
+% list environment's parameters. The user types |\\| to end a line.
+% This is implemented by |\let|'ing |\\| equal |\@centercr|.
+%
+% \begin{macrocode}
+\newenvironment{verse}
+ {\let\\=\@centercr
+ \list{}{\itemsep\z@
+ \itemindent-1.5em%
+ \listparindent\itemindent
+ \rightmargin\leftmargin
+ \advance\leftmargin1.5em}%
+ \item[]}
+ {\endlist}
+% \end{macrocode}
+% \end{environment}
+%
+% \subsubsection{Quotation}
+%
+% \begin{environment}{quotation}
+% The quotation environment is also defined by making clever use of
+% the list environment's parameters. The lines in the environment
+% are set smaller than |\textwidth|. The first line of a paragraph
+% inside this environment is indented.
+%
+% \begin{macrocode}
+\newenvironment{quotation}
+ {\list{}{%
+ \listparindent\z@
+ \itemindent\listparindent
+ \rightmargin\leftmargin
+ \parsep\z@ \@plus\p@}%
+ \item[]}
+ {\endlist}
+% \end{macrocode}
+% \end{environment}
+%
+% \subsubsection{Quote}
+%
+% \begin{environment}{quote}
+% The quote environment is like the quotation environment except
+% that paragraphs are not indented.
+%
+% \begin{macrocode}
+\newenvironment{quote}
+ {\list{}{\rightmargin\leftmargin}%
+ \item[]}
+ {\endlist}
+% \end{macrocode}
+% \end{environment}
+%
+% \subsubsection{Theorem}
+%
+% \begin{macro}{\@begintheorem}
+% \begin{macro}{\@opargbegintheorem}
+% \begin{macro}{\@endtheorem}
+% These document classes have a slightly modified \Lenv{theorem}
+% environment style. Surrounding whitespace is added and an
+% initialisation of |\labelsep|. Finally a slanted font instead of
+% an italic font is used.
+% \begin{macrocode}
+\def\@begintheorem#1#2{%
+ \vskip\baselineskip \labelsep=.5em%
+ \trivlist
+ \item[\hskip \labelsep{\bfseries #1\ #2}]\slshape}

+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \subsubsection{Titlepage}
+%
+% \begin{environment}{titlepage}
+% In the normal environments, the titlepage environment does nothing
+% but start and end a page, and inhibit page numbers. It also resets
+% the page number to zero. In two-column style, it still makes a
+% one-column page.
+%
+% \begin{macrocode}
+\newenvironment{titlepage}
+ {
+ \if@twocolumn
+ \@restonecoltrue\onecolumn
+ \else
+ \@restonecolfalse\newpage
+ \fi
+ \thispagestyle{empty}%

+ \setcounter{page}{1}%
+ \fi}
+ {\if@restonecol\twocolumn \else \newpage \fi
+ \setcounter{page}{1}%
+ }
+% \end{macrocode}
+% \end{environment}
+%
+% \subsubsection{Appendix}
+%
+% \begin{macro}{\appendix}
+%
+% The |\appendix| command is not really an environment, it is a
+% macro that makes some changes in the way things are done.
+%
+% In this document class the |\appendix| command must do the
+% following:
+% \begin{itemize}
+% \item reset the chapter and section counters to zero,
+% \item set |\@chapapp| to |\appendixname| (for messages),
+% \item redefine the chapter counter to produce appendix numbers,
+% \item possibly redefine the |\chapter| command if appendix titles
+% and headings are to look different from chapter titles and
+% headings.
+% \end{itemize}
+%
+% \begin{macrocode}
+\newcommand\appendix{\par
+ \setcounter{chapter}{0}%
+ \setcounter{section}{0}%
+ \renewcommand\@chapapp{\appendixname}%

+% \end{macrocode}
+% \end{macro}
+%
+% \subsection{Setting parameters for existing environments}
+%
+% \subsubsection{Array and tabular}
+%
+% \begin{macro}{\arraycolsep}
+% The columns in an array environment are separated by

+% environments is given by |\doublerulesep|.
+% \begin{macrocode}
+\setlength\doublerulesep{2\p@}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsubsection{Tabbing}
+%
+% \begin{macro}{\tabbingsep}
+% This controls the space that the |\'| command puts in. (See
+% \LaTeX{} manual for an explanation.)
+% \begin{macrocode}
+\setlength\tabbingsep{\labelsep}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsubsection{Minipage}
+%
+% \begin{macro}{\@minipagerestore}
+% The macro |\@minipagerestore| is called upon entry to a minipage
+% environment to set up things that are to be handled differently
+% inside a minipage environment.
+%
+% \begin{macrocode}
+%<+type1>\def\@minipagerestore{\parindent\unitindent}
+%<*type3>
+\def\@minipagerestore{%

+%</type3>
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@mpfootins}
+% Minipages have their own footnotes; |\skip||\@mpfootins| plays
+% same r\^ole for footnotes in a minipage as |\skip||\footins| does
+% for ordinary footnotes.
+%
+% \begin{macrocode}
+\skip\@mpfootins = \skip\footins
+% \end{macrocode}
+% \end{macro}
+%
+% \subsubsection{Framed boxes}
+%
+% \begin{macro}{\fboxsep}
+% The space left by |\fbox| and |\framebox| between the box and the
+% text in it.
+% \begin{macro}{\fboxrule}
+% The width of the rules in the box made by |\fbox| and |\framebox|.
+% \begin{macrocode}
+\setlength\fboxsep{3\p@}
+\setlength\fboxrule{.4\p@}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \subsubsection{Equation and eqnarray}
+%
+% \begin{macro}{\theequation}
+% The equation counter will be reset at beginning of a new chapter
+% and the equation number will be prefixed by the chapter number.
+%
+% This code must follow the |\chapter| definition, or more exactly
+% the definition of the chapter counter.
+% \begin{macrocode}
+\@addtoreset{equation}{chapter}
+\renewcommand\theequation{\thechapter.\arabic{equation}}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\jot}
+% |\jot| is the extra space added between lines of an eqnarray
+% environment. The default value is used.
+% \begin{macrocode}
+% \setlength\jot{3pt}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@eqnnum}
+% The macro |\@eqnnum| defines how equation numbers are to appear in
+% equations. Again the default is used.
+%
+% \begin{macrocode}
+% \def\@eqnnum{(\theequation)}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsection{Floating objects}
+%
+% The file \file{latex.dtx} only defines a number of tools with
+% which floating objects can be defined. This is done in the
+% document class. It needs to define the following macros for each
+% floating object of type \texttt{TYPE} (e.g., \texttt{TYPE} =
+% figure).
+%
+% \begin{description}
+% \item[\texttt{\bslash fps@TYPE}]
+% The default placement specifier for floats of type
+% \texttt{TYPE}.
+%
+% \item[\texttt{\bslash ftype@TYPE}]
+% The type number for floats of type \texttt{TYPE}. Each
+% \texttt{TYPE} has associated a unique positive {\texttt
+% TYPE} number, which is a power of two. E.g., figures might
+% have type number 1, tables type number 2, programs type
+% number 4, etc.
+%
+% \item[\texttt{\bslash ext@TYPE}]
+% The file extension indicating the file on which the contents
+% list for float type \texttt{TYPE} is stored. For example,
+% |\ext@figure| = `lof'.
+%
+% \item[\texttt{\bslash fnum@TYPE}]
+% A macro to generate the figure number for a caption. For
+% example, |\fnum@TYPE| == `Figure |\thefigure|'.
+%
+% \item[\texttt{\bslash @makecaption{\meta{num}}{\meta{text}}}]
+% A macro to make a caption, with \meta{num} the value produced
+% by |\fnum@...| and \meta{text} the text of the caption. It
+% can assume it's in a |\parbox| of the appropriate width.
+% This will be used for {\em all} floating objects.
+%
+% \end{description}
+%
+% The actual environment that implements a floating object such as
+% a figure is defined using the macros |\@float| and |\end@float|,
+% which are defined in \file{latex.dtx}.
+%
+% An environment that implements a single column floating object is
+% started with |\@float{|\texttt{TYPE}|}[|\meta{placement}|]| of type
+% \texttt{TYPE} with \meta{placement} as the placement specifier.
+% The default value of \meta{PLACEMENT} is defined by |\fps@TYPE|.
+%
+% The environment is ended by |\end@float|. E.g., |\figure| ==
+% |\@float|{figure}, |\endfigure| == |\end@float|.
+%
+% \subsubsection{Figure}
+%
+% Here is the implementation of the figure environment.
+%
+% \begin{macro}{\c@figure}
+% First we have to allocate a counter to number the figures. In
+% this document class the figures are numbered per chapter.
+% \begin{macrocode}
+\newcounter{figure}[chapter]
+\renewcommand\thefigure{\thechapter.\@arabic\c@figure}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\fps@figure}
+% \begin{macro}{\ftype@figure}
+% \begin{macro}{\ext@figure}
+% \begin{macro}{\num@figure}
+% Here are the parameters for the floating objects of type `figure'.
+% \begin{macrocode}
+\def\fps@figure{tbp}
+\def\ftype@figure{1}
+\def\ext@figure{lof}
+\def\fnum@figure{\figurename~\thefigure}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \begin{environment}{figure}
+% \begin{environment}{figure*}
+% And the definition of the actual environment. The form with the
+% |*| is used for double column figures.
+% \begin{macrocode}
+\newenvironment{figure}
+ {\@float{figure}}
+ {\end@float}
+\newenvironment{figure*}
+ {\@dblfloat{figure}}
+ {\end@dblfloat}
+% \end{macrocode}
+% \end{environment}
+% \end{environment}
+%
+% \subsubsection{Table}
+%
+% Here is the implementation of the table environment. It is very
+% much the same as the figure environment.
+%
+% \begin{macro}{\c@table}
+% First we have to allocate a counter to number the tables. In this
+% document class the tables are numbered per chapter.
+% \begin{macrocode}
+\newcounter{table}[chapter]
+\renewcommand\thetable{\thechapter.\@arabic\c@table}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\fps@table}
+% \begin{macro}{\ftype@table}
+% \begin{macro}{\ext@table}
+% \begin{macro}{\num@table}
+% Here are the parameters for the floating objects of type `table'.
+% \begin{macrocode}
+\def\fps@table{tbp}
+\def\ftype@table{2}
+\def\ext@table{lot}
+\def\fnum@table{\tablename~\thetable}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \begin{environment}{table}
+% \begin{environment}{table*}
+% And the definition of the actual environment. The form with the
+% |*| is used for double column tables.
+% \begin{macrocode}
+\newenvironment{table}
+ {\@float{table}}
+ {\end@float}
+\newenvironment{table*}
+ {\@dblfloat{table}}
+ {\end@dblfloat}
+% \end{macrocode}
+% \end{environment}
+% \end{environment}
+%
+% \subsubsection{Captions}
+%
+% \begin{macro}{\@makecaption}
+% The |\caption| command calls |\@makecaption| to format the
+% caption of floating objects. It gets two arguments,
+% \meta{number}, the number of the floating object and \meta{text},
+% the text of the caption. Usually \meta{number} contains a string
+% such as `Figure 3.2'. The macro can assume it is called inside a
+% |\parbox| of right width, with |\normalsize|.
+%
+% \begin{macro}{\abovecaptionskip}
+% \begin{macro}{\belowcaptionskip}
+% These lengths contain the amount of white space to leave above
+% and below the caption.
+% \begin{macrocode}
+\newlength\abovecaptionskip
+\newlength\belowcaptionskip
+\setlength\abovecaptionskip{10\p@}
+\setlength\belowcaptionskip{0\p@}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% The definition of this macro is |\long| in order to allow more
+% then one paragraph in a caption.
+% \begin{macrocode}
+\long\def\@makecaption#1#2{%
+ \vskip\abovecaptionskip
+% \end{macrocode}
+% We want to see if the caption fits on one line on the page,
+% therefore we first typeset it in a temporary box.
+% \begin{macrocode}
+ \sbox\@tempboxa{{\CaptionLabelFont#1:} \CaptionTextFont#2}%
+% \end{macrocode}
+% We can the measure its width. It that is larger than the current
+% |\hsize| we typeset the caption as an ordinary paragraph.
+% \begin{macrocode}
+ \ifdim \wd\@tempboxa >\hsize
+ {\CaptionLabelFont#1:} \CaptionTextFont#2\par
+% \end{macrocode}
+% If the caption fits, we center it.
+% \begin{macrocode}
+ \else
+ \hbox to\hsize{\hfil\box\@tempboxa\hfil}%
+ \fi
+ \vskip\belowcaptionskip}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\CaptionLabelFont}
+% \begin{macro}{\CaptionTextFont}
+% These macros can contain the fonts used for typesetting captions.
+% By default they do nothing.
+% \begin{macrocode}
+\newcommand\CaptionLabelFont{\relax}
+\newcommand\CaptionTextFont{\relax}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\CaptionFonts}
+% To change the fonts that are used to typeset captions
+% this macro can be used.
+% \begin{macrocode}
+\newcommand\CaptionFonts[2]{%
+ \renewcommand\CaptionLabelFont{#1}%
+ \renewcommand\CaptionTextFont{#2}%
+ }
+% \end{macrocode}
+% \end{macro}
+%
+% \subsection{Font changing}
+%
+% Here we supply the declarative font changing commands that were
+% common in \LaTeX\ version 2.09 and earlier. These commands work
+% in text mode \emph{and} in math mode. They are provided for
+% compatibility, but one should start using the |\text...| and
+% |\math...| commands instead. These commands are defined using
+% |\DeclareOldFontCommand|, a command with three arguments: the user
+% command to be defined; \LaTeX\ commands to execute in text mode
+% and \LaTeX\ commands to execute in math mode.
+%
+% \begin{macro}{\rm}
+% \begin{macro}{\tt}
+% \begin{macro}{\sf}
+%
+% The commands to change the family. When in compatibility mode we
+% select the `default' font first, to get \LaTeX2.09 behviour.
+% \begin{macrocode}
+\DeclareOldFontCommand{\rm}{\normalfont\rmfamily}{\mathrm}
+\DeclareOldFontCommand{\sf}{\normalfont\sffamily}{\mathsf}
+\DeclareOldFontCommand{\tt}{\normalfont\ttfamily}{\mathtt}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\bf}
+% The command to change to the bold series. One should use
+% |\mdseries| to explicitly switch back to medium series.
+% \begin{macrocode}
+\DeclareOldFontCommand{\bf}{\normalfont\bfseries}{\mathbf}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\sl}
+% \begin{macro}{\it}
+% \begin{macro}{\sc}
+%
+% And the commands to change the shape of the font. The slanted and
+% small caps shapes are not available by default as math alphabets,
+% so those changes do nothing in math mode. One should use
+% |\upshape| to explicitly change back to the upright shape.
+% \begin{macrocode}
+\DeclareOldFontCommand{\it}{\normalfont\itshape}{\mathit}
+\DeclareOldFontCommand{\sl}{\normalfont\slshape}{\relax}
+\DeclareOldFontCommand{\sc}{\normalfont\scshape}{\relax}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\cal}
+% \begin{macro}{\mit}
+%
+% The commands |\cal| and |\mit| should only be used in math mode,
+% outside math mode they have no effect. Currently the New Font
+% Selection Scheme defines these commands to generate warning
+% messages. Therefore we have to define them `by hand'.
+% \begin{macrocode}
+\renewcommand{\cal}{\protect\pcal}
+\newcommand{\pcal}{\@fontswitch{\relax}{\mathcal}}
+\renewcommand{\mit}{\protect\pmit}
+\newcommand{\pmit}{\@fontswitch{\relax}{\mathnormal}}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\pem}
+% The definition of |\pem| is changed here to have slanted instead
+% of italic fonts.
+% \begin{macrocode}
+\def\pem{\@nomath\em \ifdim \fontdimen\@ne\font >\z@
+ \upshape \else \slshape \fi}
+% \end{macrocode}
+% \end{macro}
+%
+% \section{Cross Referencing}
+% \subsection{Table of Contents, etc.}
+%
+% A |\section| command writes a
+% |\contentsline{section}{|\meta{title}|}{|\meta{page}|}| command
+% on the \file{.toc} file, where \meta{title} contains the
+% contents of the entry and \meta{page} is the page number. If
+% sections are being numbered, then \meta{title} will be of the
+% form |\numberline{|\meta{num}|}{|\meta{heading}|}| where
+% \meta{num} is the number produced by |\thesection|. Other
+% sectioning commands work similarly.
+%
+% A |\caption| command in a `figure' environment writes
+%
+% |\contentsline{figure}{\numberline{|\meta{num}|}{|%
+% \meta{caption}|}}{|\meta{page}|}|
+%
+% on the .\file{lof} file, where \meta{num} is the number produced
+% by |\thefigure| and \meta{caption} is the figure caption. It
+% works similarly for a `table' environment.
+%
+% The command |\contentsline{|\meta{name}|}| expands to
+% |\l@|\meta{name}. So, to specify the table of contents, we must
+% define |\l@chapter|, |\l@section|, |\l@subsection|, ... ; to
+% specify the list of figures, we must define |\l@figure|; and so
+% on. Most of these can be defined with either the
+% |\@dottedtocline| or the |\@regtocline| command, which work as
+% follows.
+%
+% |\@dottedtocline{|\meta{level}|}{|\meta{indent}|}{|^^A
+% \meta{numwidth}|}{|^^A
+% \meta{title}|}{|\meta{page}|}|
+%
+% |\@regtocline{|\meta{level}|}{|\meta{title}|}{|\meta{page}|}|
+%
+% \begin{description}
+% \item[\meta{level}] An entry is produced only if\meta{ level}
+% $<=$ value of the \Lcount{tocdepth} counter. Note,
+% |\chapter| is level 0, |\section| is level 1, etc.
+% \item[\meta{indent}] The indentation from the outer left margin
+% of the start of the contents line.
+% \item[\meta{numwidth}] The width of a box in which the section
+% number is to go, if \meta{title} includes a |\numberline|
+% command.
+% \end{description}
+%
+% \begin{macro}{\@pnumwidth}
+% \begin{macro}{\@tocrmarg}
+% \begin{macro}{\@dotsep}
+% This command uses the following three parameters, which are set
+% with a |\newcommand| (so em's can be used to make them depend upon
+% the font).
+% \begin{description}
+% \item[\texttt{\bslash @pnumwidth}] The width of a box in which the
+% page number is put.
+% \item[\texttt{\bslash @tocrmarg}] The right margin for multiple
+% line entries. One wants |\@tocrmarg| > or = |\@pnumwidth|
+% \item[\texttt{\bslash @dotsep}] Separation between dots, in mu
+% units. Should be defined as a number like 2 or 1.7
+% \end{description}
+%
+% \begin{macrocode}
+\newcommand\@pnumwidth{1.55em}
+\newcommand\@tocrmarg {2.55em}
+\newcommand\@dotsep{4.5}
+\setcounter{tocdepth}{2}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \subsubsection{Table of Contents}
+%
+% \begin{macro}{\tableofcontents}
+% This macro is used to request that \LaTeX{} produces a table of
+% contents. The tables of contents, figures etc. are always set in
+% single-column style.
+%
+% \begin{macrocode}
+\newcommand\tableofcontents{%
+ \if@twocolumn
+ \@restonecoltrue\onecolumn

+% Each sectioning command needs an additional macro to format its

+%
+% First we make sure that if a pagebreak should occur, it occurs

+%
+% First we have the definition from the standard classes.

+\if@oldtoc
+\newcommand\l@part[2]{%
+ \addpenalty{-\@highpenalty}%
+ \addvspace{2.25em \@plus\p@}%

+% \end{macrocode}
+% The macro |\numberline| requires that the width of the box that
+% holds the part number is stored in \LaTeX's scratch register
+% |\@tempdima|. Therefore we put it there.
+% \begin{macrocode}
+ \setlength\@tempdima{3em}%
+% \end{macrocode}
+% The we set |\parindent| to 0pt and use |\rightskip| to leave
+% enough room for the pagenumbers. To prevent overfull box messages
+% the |\parfillskip| is set to a negative value.
+% \begin{macrocode}
+ \parindent \z@ \rightskip \@pnumwidth
+ \parfillskip -\@pnumwidth
+% \end{macrocode}
+% Now we can set the entry, in a large bold font. We make sure to
+% leave vertical mode, set the part title and add the pagenumber,
+% set flush right.
+% \begin{macrocode}
+ {\leavevmode
+ \large \bfseries #1\hfil \hbox to\@pnumwidth{\hss #2}}\par

+% Prevent a pagebreak immediately after this entry, but use

+% \subsection{The index}
+%
+% \begin{environment}{theindex}
+% The environment `theindex' can be used for indices. It makes an
+% index with two columns, with each entry a seperate paragraph. At
+% the user level the commands |\item|, |\subitem| and |\subsubitem|
+% are used to produce index entries of various levels. When a new

+%
+% \subsection{Footnotes}
+%
+% \begin{macro}{\footnoterule}
+% Usually, footnotes are separated from the main body of the text
+% by a small rule. This rule is drawn by the macro |\footnoterule|.
+% We have to make sure that the rule takes no vertical space (see
+% \file{plain.tex}) so we compensate for the natural heigth of the
+% rule of 0.4pt by adding the right amount of vertical skip.
+%
+% To prevent the rule from colliding with the footnote we first add
+% a little negative vertical skip, then we put the rule and add
+% some positive vertical skip.
+% \begin{macrocode}
+\renewcommand\footnoterule{%
+ \kern-3\p@
+ \kern.5\baselineskip
+ \hrule\@width\unitindent
+ \kern.4\baselineskip
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\c@footnote}
+% Footnotes are numbered within chapters.
+% \begin{macrocode}
+% \newcounter{footnote}
+\@addtoreset{footnote}{chapter}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@makefntext}
+% The footnote mechanism of \LaTeX{} calls the macro |\@makefntext|
+% to produce the actual footnote. The macro gets the text of the
+% footnote as its argument and should use |\@thefnmark| as the mark
+% of the footnote. The macro |\@makefntext|is called when
+% effectively inside a |\parbox| of width |\columnwidth| (i.e.,
+% with |\hsize| = |\columnwidth|).
+%
+% An example of what can be achieved is given by the following piece
+% of \TeX\ code.
+% \begin{verbatim}
+% \long\def\@xmakefntext#1#2{%
+% %<-type3> \parindent=.5\unitindent
+% %<+type3> \parindent=\z@\parskip=.5\baselineskip
+% \def\labelitemi{--}\@revlabeltrue
+% {\setbox0=\hbox {#1\hskip.5em plus 1fil}%
+% \dimen0=2\wd0
+% \ifdim\dimen0>\unitindent
+% \global\unitindent=\dimen0
+% \@indentset
+% \fi}%
+% \@setpar{\@@par
+% \@tempdima \hsize
+% \advance\@tempdima-.5\unitindent
+% \parshape \@ne .5\unitindent \@tempdima}%
+% \par
+% \noindent\llap{\hbox to .5\unitindent{#1\hfil}}#2}
+% \end{verbatim}
+% The effect of this definition is that all lines of the footnote
+% are indented by 10pt, while the first line of a new paragraph is
+% indented by 1em. To change these dimensions, just substitute the
+% desired value for `10pt' (in both places) or `1em'. The mark is
+% flushright against the footnote.
+%
+% In these document classes we use a simpler macro, in which the
+% footnote text is set like an ordinary text paragraph, with no
+% indentation except on the first line of the footnote. Thus, all
+% the macro must do is set |\parindent| to the appropriate value
+% for succeeding paragraphs and put the proper indentation before
+% the mark. We change the label of itemized lists inside footnotes
+% and need to check that the |\unitindent| is large enough for our
+% purposes.
+%
+% For most of the document classes produced from this file we need
+% a slightly modified |\@makefntext| on the title page, so we
+% introduce an extra macro, |\@xmakefntext|.
+% \begin{macrocode}
+\def\@makefntext{\@xmakefntext{$\m@th\@thefnmark$.}}
+\long\def\@xmakefntext#1{%
+ \parindent\z@
+ \def\labelitemi{--}\@revlabeltrue
+ {\setbox0=\hbox {#1\hskip.5em plus 1fil}
+ \dimen0=2\wd0\relax
+ \ifdim\dimen0>\unitindent
+ \global\unitindent=\dimen0\relax
+ \@indentset
+ \fi}
+ \leavevmode\hbox to .5\unitindent{#1\hfil}}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@makefnmark}
+% The footnote markers that are printed in the text to point to the
+% footnotes should be produced by the macro |\@makefnmark|. We use
+% the default definition for it.
