% \section{Introduction}
%
%    This file contains the document class \cls{brief} that was made
%    available by Working Group 13 of the NTG (Nederlandstalige \TeX\
%    Gebruikersgroep). It defines more commands than the standard
%    document class \cls{letter}, but a letter made with the
%    \cls{letter} document class is still processable with this
%    document class.
%
% \StopEventually
%
% \section{Initial Code}
%
%    In this part we define a few comands 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}
%<*brief>
\newcommand*\@ptsize{}
%    \end{macrocode}
% \end{macro}
%
%  \begin{macro}{\if@typhulp}
%    This switch is used to decide whether or not to put a small line
%    on the paper that is used to align the paper in a typewriter.
%    \begin{macrocode}
\newif\if@typhulp
%    \end{macrocode}
%  \end{macro}
%
%  \begin{macro}{\if@streepjes}
%    A switch to indicate if the `folding lines' should be printed
%    \begin{macrocode}
\newif\if@streepjes
%    \end{macrocode}
%  \end{macro}
%
%  \begin{macro}{\if@adresrechts}
%    This switch indicates if the addressing information is to be set
%    on the left or on the right side of the letter.
%    \begin{macrocode}
\newif\if@adresrechts
%    \end{macrocode}
%  \end{macro}
%
%  \begin{macro}{\if@elfinch}
%    A switch to remember whether we are using A4 or letter
%    paper. (possibly obsolete)
%    \begin{macrocode}
\newif\if@elfinch
%    \end{macrocode}
%  \end{macro}
%
%
% \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.
%    \begin{macrocode}
\DeclareOption{a4paper}
   {\setlength\paperheight {297mm}%
    \setlength\paperwidth  {210mm}\@elfinchfalse}
\DeclareOption{a5paper}
   {\ClassWarning{brief}{Paper size A5 not supported, using A4}%
    \setlength\paperheight {297mm}%
    \setlength\paperwidth  {210mm}\@elfinchfalse}
\DeclareOption{b5paper}
   {\ClassWarning{brief}{Paper size B5 not supported, using A4}%
    \setlength\paperheight {297mm}%
    \setlength\paperwidth  {210mm}\@elfinchfalse}
\DeclareOption{letterpaper}
   {\setlength\paperheight {11in}%
    \setlength\paperwidth  {8.5in}\@elfinchtrue}
\DeclareOption{USletter}
   {\setlength\paperheight {11in}%
    \setlength\paperwidth  {8.5in}\@elfinchtrue}
\DeclareOption{legalpaper}
   {\ClassWarning{brief}
                 {Paper size `legal' not supported, using `letter'}%
    \setlength\paperheight {14in}%
    \setlength\paperwidth  {8.5in}\@elfinchtrue}
\DeclareOption{executivepaper}
   {\ClassWarning{brief}
                 {Paper size `executive' not supported, using `letter'}%
    \setlength\paperheight {10.5in}%
    \setlength\paperwidth  {7.25in}\@elfinchtrue}
%    \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 wont 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}
%
%    Two-sided printing was not supported in the \LaTeX~2.09 version
%    of this documentclass.
%    \begin{macrocode}
\if@compatibility
  \DeclareOption{twoside}{\@latexerr{No 'twoside' layout for letters}%
                                   \@eha}
\else
  \DeclareOption{twoside}{\@twosidetrue  \@mparswitchtrue}
\fi
%    \end{macrocode}
%
%
%    \begin{macrocode}
\DeclareOption{oneside}{\@twosidefalse \@mparswitchfalse}
%    \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{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{Typewriter alignment}
%
%    \begin{macrocode}
\DeclareOption{typhulp}{\@typhulptrue}
\DeclareOption{geentyphulp}{\@typhulpfalse}
%    \end{macrocode}
%  \subsection{Folding lines}
%    It is possible to print `folding lines' on the far right side of
%    the paper. 
%
%    \begin{macrocode}
\DeclareOption{streepjes}{\@streepjestrue}
\DeclareOption{geenstreepjes}{\@streepjesfalse}
%    \end{macrocode}
%
%  \subsection{Address placement}
%    The address information can be put either on the left or on the
%    right side of the letter
%
%    \begin{macrocode}
\DeclareOption{adreslinks}{\@adresrechtsfalse}
\DeclareOption{adresrechts}{\@adresrechtstrue}
%    \end{macrocode}
%
% \subsection{Support for different languages}
%
%    In the original document style \cls{brief} the options to support
%    the various languages were all dutch words. To be compatible with
%    both the old version of the document class and with the
%    recommended set of language options we have at least two options
%    for each language.
%
%     First Dutch,
%    \begin{macrocode}
\DeclareOption{nederlands}{\AtEndOfClass{\dutchbrief}}
\DeclareOption{dutch}     {\AtEndOfClass{\dutchbrief}}
%    \end{macrocode}
%     then British English,
%    \begin{macrocode}
\DeclareOption{engels}    {\AtEndOfClass{\englishbrief}}
\DeclareOption{english}   {\AtEndOfClass{\englishbrief}}
%    \end{macrocode}
%    American English,
%    \begin{macrocode}
\DeclareOption{USengels}  {\AtEndOfClass{\americanbrief}}
\DeclareOption{american}  {\AtEndOfClass{\americanbrief}}
%    \end{macrocode}
%    German
%    \begin{macrocode}
\DeclareOption{duits}     {\AtEndOfClass{\germanbrief}}
\DeclareOption{german}    {\AtEndOfClass{\germanbrief}}
%    \end{macrocode}
%    and finally french.
%    \begin{macrocode}
\DeclareOption{frans}     {\AtEndOfClass{\frenchbrief}}
\DeclareOption{french}    {\AtEndOfClass{\frenchbrief}}
\DeclareOption{francais}  {\AtEndOfClass{\frenchbrief}}
%    \end{macrocode}
%
% \section{Executing Options}
%
%    Here we execute the default options to initialize certain
%    variables.
%    \begin{macrocode}
\ExecuteOptions{a4paper,11pt,oneside,onecolumn,final,%
                geentyphulp,geenstreepjes,adreslinks,%
                nederlands}
%    \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.
% \changes{v2.0h}{1994/12/30}{Added a \cs{relax} to prevent an
%    incomplete \cs{ifcase} error}
%    \begin{macrocode}
\ProcessOptions\relax
%    \end{macrocode}
%    Now that all the options have been executed we can define the
%    user-level size changing commands. Their definition depends on
%    which of the \Lopt{10pt}, \Lopt{11pt} or \Lopt{12pt} options was
%    specified. 
%
%  \begin{macro}{\normalsize}
%  \begin{macro}{\@normalsize}
%    
%    The user level command for the main size is |\normalsize|.
%    Internally \LaTeX{} uses |\@normalsize| when it refers to the
%    main size. |\@normalsize| will be defined to work like
%    |\normalsize| if the latter is redefined from its default
%    definition (that just issues an error message). Otherwise
%    |\@normalsize| simply selects a 10pt/12pt size.
%
%    The |\normalsize| macro also sets new values for\\
%    |\abovedisplayskip|, |\abovedisplayshortskip| and
%
%    \begin{macrocode}
\ifcase\@ptsize
  \renewcommand*\normalsize{%
    \@setfontsize\normalsize\@xpt\@xiipt

% \label{sec:maincode}
%
%  In this section we are finally dealing with the nasty typographical
%  details.
%
% \subsection{Fonts}
%
%    We use two fixed fonts in these letters.
%^^A possibly need to update for DC fonts in future?
%    \begin{macrocode}
\newfont\refkopfont{cmssq8}
\DeclareFixedFont\kleinvet{\encodingdefault}%
                          {\rmdefault}%
                          {\bfdefault}%
                          {\shapedefault}%
                          {7}
%    \end{macrocode}
% \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}{\parskip}
% \begin{macro}{\parindent}
%    |\parskip| gives extra vertical space between paragraphs and
%    |\parindent| is the width of the paragraph indentation.
%    Letters are typeset without paragraph indentation.
%    \begin{macrocode}
\setlength\parskip{0.7em \@plus .3em \@minus .2em}
\setlength\parindent{0\p@}
%    \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|,
%    dependant 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 discourage 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}
%    Discourage (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}
%
%
% \subsection{Page Layout}
%
%    All margin dimensions are measured from a point one inch from the
%    top and lefthand side of the page.
%
% \subsubsection{Vertical spacing}
%
% \begin{macro}{\headheight}
% \begin{macro}{\headsep}
%    The |\headheight| is the height of the box that will contain the
%    running head. The |\headsep| is the distance between the bottom
%    of the running head and the top of the text. |\topskip| is the
%    |\baselineskip| for the first line on a page.
%    \begin{macrocode}
\setlength\headheight{37mm}
\setlength\headsep   {0mm}
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\footskip}
%    The distance from the baseline of the box which contains the
%    running footer to the baseline of last line of text is controlled
%    by the |\footskip|.
%    Bottom of page:
%    \begin{macrocode}
\setlength\footskip{25\p@}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\maxdepth}
% \begin{macro}{\@maxdepth}
%    The \TeX\ primitive register |\maxdepth| has a function that is
%    similar to that of |\topskip|. The register |\@maxdepth| should
%    always contain a copy of |\maxdepth|. In both plain \TeX\ and
%    \LaTeX~2.09 |\maxdepth| had a fixed value of \texttt{4pt}; in
%    native \LaTeX2e\ mode we let the value depend on the typesize. We
%    set it so that |\maxdepth| $+$ |\topskip| $=$ typesize $\times
%    1.5$. As it happens, in these classes |\topskip| is equal to the
%    typesize, therefor we set |\maxdepth| to half the value of
%    |\topskip|.
%    \begin{macrocode}
\if@compatibility
  \setlength\maxdepth{4\p@}
\else
  \setlength\maxdepth{.5\topskip}
\fi
\setlength\@maxdepth\maxdepth
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
% \subsubsection{The dimension of text}
%
% \begin{macro}{\textwidth}
% \begin{macro}{\textheight}
%    The dimensions of the text are fixed; they are defined in the
%    \textsc{nen} norm which this class implements.
%
%    \begin{macrocode}
\setlength\textwidth{144mm}
\setlength\textheight{197mm}
\if@elfinch \addtolength\textheight{-17.6mm} \fi
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
%  \begin{macro}{\rightskip}
%  \begin{macro}{\@rightskip}
%    
%    \begin{macrocode}
\setlength\@rightskip{0cm \@plus 5cm}
\setlength\rightskip{\@rightskip}
%    \end{macrocode}
%  \end{macro}
%  \end{macro}
%
% \subsubsection{Margins}
%
% \begin{macro}{\oddsidemargin}
% \begin{macro}{\evensidemargin}
% \begin{macro}{\marginparwidth}
%    Again, these dimensions are based on the \textsc{nen} norm.
%    \begin{macrocode}
\setlength\@tempdima{\paperwidth}
\addtolength\@tempdima{-2in}
\addtolength\@tempdima{-\textwidth}
\setlength\oddsidemargin   {7.6mm}
\setlength\evensidemargin  {\oddsidemargin}
\setlength\marginparwidth  {0\p@}
%    \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\marginparsep}
% \begin{macro}{\marginparpush}
%    The horizontal space between the main text and marginal notes is
%    determined by |\marginparsep|, the minimum vertical separation
%    between two marginal notes is controlled by |\marginparpush|.
%    \begin{macrocode}
\setlength\marginparsep {0\p@}
\setlength\marginparpush{0\p@}
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\topmargin}
%    The |\topmargin| is the distance between the top of `the
%    printable area' --which is 1 inch below the top of the paper--
%    and the top of the box which contains the running head.
%
%    \begin{macrocode}
\setlength\topmargin{-12.4mm}
%    \end{macrocode}
% \end{macro}
%
% \subsubsection{The address field}
%
%    The address information has to be put on a specific place.
%
%  \begin{macro}{\vensterskip}
%  \begin{macro}{\@vensterskip}
%    
%    \begin{macrocode}
\newdimen\vensterskip
\setlength\vensterskip{50mm}
\newdimen\@vensterskip
%    \end{macrocode}
%  \end{macro}
%  \end{macro}
%
% \subsubsection{Changing head and text heights}
%
%    This class has a much higher head on the first page of a letter
%    than on subsequent pages.
%
%  \begin{macro}{\@firstheadheight}
%  \begin{macro}{\@otherheadheight}
%  \begin{macro}{\@othertextheight}
%  \begin{macro}{\@otherheadsep}
%  \begin{macro}{\@vervolgsep}
%    
%    \begin{macrocode}
\newdimen\@firstheadheight
\newdimen\@otherheadheight
\newdimen\@othertextheight
\newdimen\@otherheadsep
\newdimen\@vervolgsep
\setlength\@otherheadsep{2mm}
%    \end{macrocode}
%  \end{macro}
%  \end{macro}
%  \end{macro}
%  \end{macro}
%  \end{macro}
%
%  \begin{macro}{\@prepareerhoofden}
%    
%    \begin{macrocode}
\def\@prepareerhoofden{%
  \setlength\@vensterskip{\vensterskip}%
  \addtolength\@vensterskip{-50mm}%
  \setlength\@firstheadheight{\headheight}%
  \setlength\@otherheadheight{\headheight}%
  \setlength\@othertextheight{\textheight}%
  }
%    \end{macrocode}
%  \end{macro}
%
% \subsubsection{Information in the foot}
%
%    We also reserve some space at the bottom of the paper to print
%    some information about the sender of the letter.
%
%  \begin{macro}{\footsep}
%    The distance between the text and this foot information
%    \begin{macrocode}
\newdimen\footsep
\setlength\footsep{15mm}
%    \end{macrocode}
%  \end{macro}
%
% \subsubsection{Footnotes}
%
% \begin{macro}{\footnotesep}
%    |\footnotesep| is the height of the strut placed at the beginning
%    of every footnote. It equals the  height of a normal
%    |\footnotesize| strut in this
%    class, thus no extra space occurs between footnotes.
%    \begin{macrocode}
\setlength\footnotesep{12\p@}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\footins}
%    |\skip\footins| is the space between the last line of the main
%    text and the top of the first footnote.
%    \begin{macrocode}
\setlength{\skip\footins}{10\p@ \@plus 2\p@ \@minus 4\p@}
%    \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}
%
% \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 pagestyles \pstyle{empty} and \pstyle{plain} are defined in
%    the \LaTeX{} kernel (\file{ltpage.dtx}), but these definitions
%    are changed to a simpler version for this document class.
%
% \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 contain some information about the sender of the
%    letter. The feet aer the same for even and odd pages.
%    \begin{macrocode}
      \def\@oddfoot{\voetregel\hss}%
      \let\@evenfoot\@oddfoot
%    \end{macrocode}
%    The running head contains some information about this letter. The
%    head is the same for even and odd pages.
%    \begin{macrocode}
      \def\@oddhead{%
        \vbox to \@otherheadheight
          {\vervolghoofd\vfil
           \if@streepjes\streepjes{\@firstheadheight}\fi}\hss}
      \let\@evenhead\@oddhead}
%    \end{macrocode}
%    For one sided printing we don't need to define |\@evenhead| so
%    the definition is somewhat simpler.
% \changes{v2.0e}{1994/07/12}{Removed a typo (\cs{othertheadheight})}

\fi
%    \end{macrocode}
% \end{macro}
%
%
%  \begin{macro}{\ps@firstpage}

% \subsection{The generic letter commands}
%
% \begin{environment}{brief}
%     The \Lenv{brief} environment creates a new letter, starting from
%    page 1.  (The first page is unnumbered.)  It has a single
%    argument, which is the adressee and his address, as in
%\begin{verbatim}
%  \begin{brief}{Sam Jones \\
%                 Institute for Retarded Study\\
%                 Princeton, N.J.}
%\end{verbatim}
%     Local declarations, such as |\address|, can follow the
%     |\begin{brief}|.
%    \begin{macrocode}
\newenvironment{brief}[1]
  {\newpage
    \if@twoside \ifodd\c@page
                \else\thispagestyle{empty} \hbox{}\newpage\fi
    \fi
    \c@page\@ne
    \interlinepenalty=200 % smaller than the TeXbook value
%    \end{macrocode}
%    The |\leavevmode| and |\ignorespaces| commands are there for
%    protecting against an empty argument.
%    \begin{macrocode}
    \@processto{\leavevmode\ignorespaces #1}%
%    \end{macrocode}
%    Now we can start filling in the various fields in the references
%    line. First the adressee.
%    \begin{macrocode}
    \@defrefveld{\@Ad}{\geadresseerdetekst}{\toname}
%    \end{macrocode}
%    Then the date. When nothing was specified we use |\vandaag|.
%    \begin{macrocode}
    \ifdim\wd\@Dt=0cm \@defrefveld{\@Dt}{\datumtekst}{\vandaag}\fi
%    \end{macrocode}
%    Now we can prepare the letterheads. It couldn't be done earlier
%    because the user can specify that he uses a different kind of
%    `window envelope'.
%    \begin{macrocode}
    \@prepareerhoofden
%    \end{macrocode}
%    We may need to adapt the height of the head and the text body on
%    the following pages. Therefore we measure the height of the head
%    on those pages.
%    \begin{macrocode}
    {\setbox\@tempboxa\vervolghoofd
      \@tempdima\ht\@tempboxa
      \advance\@tempdima by -\@otherheadheight
      \ifdim\@tempdima>0\p@
        \global\advance\@otherheadheight by \@tempdima
        \global\advance\@othertextheight by -\@tempdima
      \fi}
%    \end{macrocode}
%    We have to do the same for the foot of the letter.
%    \begin{macrocode}
    {\setbox\@tempboxa=\vbox{\voetregel}
      \global\footskip=\ht\@tempboxa

%       More precisely, it is the first argument of the |\mlabel|
%       command described below. It should be defined to null if the
%       return address doesn't appear on the labels.  Any command,
%       other than |\\|, that should not be expanded until the |\mlabel|
%       command is actually executed must be preceded by |\protect|.
%       Whenever possible, |\protect| commands in the definition of
%       |\returnaddress|---it's much more efficient that way.  In

% \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
%    \texttt{K}th level list, the command |\@listK| is called, where
%    `\texttt{K'} denotes `\texttt{i}', `\texttt{ii}', ... ,
%    `\texttt{vi}'.  (I.e., |\@listiii| is called for a third-level
%    list.)  By convention, |\@listK| should set |\leftmargin| to
%    |\leftmarginK|.
%
% \begin{macro}{\leftmargin}
% \begin{macro}{\leftmargini}
% \begin{macro}{\leftmarginii}
% \begin{macro}{\leftmarginiii}

% \begin{macro}{\leftmarginv}
% \begin{macro}{\leftmarginvi}
%    For efficiency, level-one list's values are defined at top level,
%    and |\@listi| is defined to set only |\leftmargin|.
%    \begin{macrocode}
\setlength\leftmargini  {2.5em}
%    \end{macrocode}
%    The following three are calculated so  that they are larger than
%    the sum of |\labelsep| and the width of the default labels (which
%    are `(m)', `vii.' and `M.').

%
% \begin{macro}{\labelitemi}

% \begin{macro}{\labelitemiv}
%    Itemization is controlled by  |\labelitemi|, |\labelitemii|,

% \subsection{Defining new environments}
%
% \subsubsection{Verse}
%
% \begin{environment}{verse}

% \subsubsection{Quotation}
%
% \begin{environment}{quotation}
%   The quotation environment is also defined by making clever use of

%   are set smaller than |\textwidth|. The first line of a paragraph
%   inside this environment is indented.
%

% \end{macro}
%
% \begin{macro}{\arrayrulewidth}
%    The width of vertical rules in the array and tabular environments

%    \end{macrocode}
% \end{macro}
%
% \subsubsection{Tabbing}
%
% \begin{macro}{\tabbingsep}
%    This controls the space that the |\'| command puts in. (See

%    \begin{macrocode}
\setlength\tabbingsep{\labelsep}
%    \end{macrocode}
% \end{macro}
%
% \subsubsection{Minipage}
%
% \begin{macro}{\@minipagerestore}
%    The macro |\@minipagerestore| is called upon entry to a minipage

%    inside a minipage environment. In the current styles, it does
%    nothing.
% \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}

% \begin{macro}{\theequation}
%    The equation counter will be typeset using arabic numbers.
%    \begin{macrocode}
\renewcommand*{\theequation}{\@arabic\c@equation}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\jot}
%    |\jot| is the extra space added between lines of an eqnarray

%    \begin{macrocode}
% \setlength\jot{3pt}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\@eqnnum}
%    The macro |\@eqnnum| defines how equation numbers are to appear in

% \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
%    compatiblity, but one should start using the |\text...| and
%    |\math...| commands instead. These commands are redefined using
%    |\@renewfontswitch|, 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.
%    \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'.
% \changes{v2.0g}{1994/12/23}{Now define \cs{cal} and \cs{mit} using
%    \cs{DeclareRobustCommand*}}
%    \begin{macrocode}
\DeclareRobustCommand*{\cal}{\@fontswitch{\relax}{\mathcal}}
\DeclareRobustCommand*{\mit}{\@fontswitch{\relax}{\mathnormal}}
%    \end{macrocode}
%  \end{macro}
%  \end{macro}
%
% \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 make
%    sure we end up at the same point where we begun this operation.
%    \begin{macrocode}
\renewcommand*{\footnoterule}{%
  \kern-\p@
  \hrule \@width .4\columnwidth
  \kern .6\p@}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\c@footnote}
%    Footnotes are numbered within chapters in the report and book
%    document styles.
%    \begin{macrocode}
% \newcounter{footnote}
%    \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 |\@makefnmark| to produce
%    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\@makefntext#1{%
%             \@setpar{\@@par
%                      \@tempdima = \hsize
%                      \advance\@tempdima-10pt
%                      \parshape \@ne 10pt \@tempdima}%
%             \par
%             \parindent 1em\noindent
%             \hb@xt@\z@{\hss\@makefnmark}#1}
% \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 a paragraph, and 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.
%
% \changes{v2.0q}{1997/09/08}{As we want to have different appearances
%    of the footnotemarker in the text and in the footnotes, we can't
%    use \cs{@makefnmark} here}
%    \begin{macrocode}
\long\def\@makefntext#1{%
  \noindent\hb@xt@\leftmargini{\normalfont\@thefnmark.\hfil}#1}
%    \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|.
% \changes{v2.0l}{1995/08/10}{No longer use hidden math}
% \changes{v2.0q}{1997/09/08}{Use the default definition for
%    \cs{@makefnmark}}

% \subsection{Words}

%    This document class supports a number of languages. All words
%    that will be printed byu the class code are stored in commands
%    which can be redefined if you want to use a different language.
