%
% \section{Opcje klasy}
%
%
% \subsection*{Formaty papieru}
%
%    [Przydao by si tu co doda]
%    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{a6paper}
   {\setlength\paperheight {148mm}%
    \setlength\paperwidth  {105mm}}
\DeclareOption{b4paper}
   {\setlength\paperheight {353mm}%
    \setlength\paperwidth  {250mm}}
\DeclareOption{b5paper}
   {\setlength\paperheight {250mm}%
    \setlength\paperwidth  {176mm}}
\DeclareOption{b6paper}
   {\setlength\paperheight {176mm}%
    \setlength\paperwidth  {125mm}}
\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 were given for portrait
%    paper.
%    \begin{macrocode}
\DeclareOption{landscape}
   {\setlength\@tempdima   {\paperheight}%
    \setlength\paperheight {\paperwidth}%
    \setlength\paperwidth  {\@tempdima}}
%    \end{macrocode}
%    Opcja \Lopt{wide} powoduje stosowanie minimalnych marginesw.
%    \begin{macrocode}
\newif\if@wide
\DeclareOption{wide}
    {\@widetrue}
%    \end{macrocode}
%    Opcje \Lopt{withmarginpar} i~\Lopt{withoutmarginpar} decyduj, czy
%    zostawiamy na stronie miejsce na marginalia.
%    \begin{macrocode}
\newif\if@marginparsused
\DeclareOption{withmarginpar}
    {\@marginparsusedtrue}
\DeclareOption{withoutmarginpar}
    {\@marginparsusedfalse}
%    \end{macrocode}
%
% \subsection*{Wybr podstawowego stopnia pisma}
%
%    \begin{macrocode}
\newcommand\mw@usedd{\p@=1dd
 \def\@vpt{5dd}%
 \def\@vipt{6dd}%
 \def\@viipt{7dd}%
 \def\@viiipt{8dd}%
 \def\@ixpt{9dd}%
 \def\@xpt{10dd}%
 \def\@xipt{11dd}%
 \def\@xiipt{12dd}%
 \def\@xivpt{14dd}%
 \def\@xviipt{16dd}%
 \def\@xxpt{18dd}%
 \def\@xxvpt{24dd}%
}
\DeclareOption{10pt}{\renewcommand\@ptsize{0}\def\@basesize{10}}
\DeclareOption{10dd}{\renewcommand\@ptsize{0}\def\@basesize{10}\@usedd}
\DeclareOption{11pt}{\renewcommand\@ptsize{1}\def\@basesize{11}}
\DeclareOption{12pt}{\renewcommand\@ptsize{2}\def\@basesize{12}}
%    \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.
%    \begin{macrocode}
%<book>\@openrighttrue
%<!article>\DeclareOption{openright}{\@openrighttrue}
%<!article>\DeclareOption{openany}{\@openrightfalse}
%    \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. It loads code which is generated
%    automatically from the kernel files when the format is built.
%    If the equation number does get a special formatting then instead
%    of using the kernel file the class would need to provide the code
%    explicitly.
%    \begin{macrocode}
\DeclareOption{leqno}{\input{leqno.clo}}
%    \end{macrocode}
%
%  \subsection*{Flush left displays}
%
%    The option \Lopt{fleqn} redefines the displayed math environments
%    in such a way that they come out flush left, with an indentation
%    of |\mathindent| from the prevailing left margin. It loads
%    code which is generated
%    automatically from the kernel files when the format is built.
%    \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}{%
%    \end{macrocode}
%    First some hook into the bibliography environment is filled.
%    \begin{macrocode}
  \AtEndOfPackage{%
   \renewcommand\@openbib@code{%
      \advance\leftmargin\bibindent
      \itemindent -\bibindent
      \listparindent \itemindent
      \parsep \z@
      }%
%    \end{macrocode}
%    In addition the definition of |\newblock| is overwritten.
%    \begin{macrocode}
   \renewcommand\newblock{\par}}%
}
%    \end{macrocode}
%
% \subsection*{Krj pisma tytulariw}
%    Nastpne opcje su do wyboru kroju (rodziny fontw), ktrym
%    skadane bd nagwki rozdziaw.
%    \begin{macrocode}

%    \end{macrocode}
%
% \subsection*{Stopie pisma w~rodowiskach przemieszczalnych}
%    
%    \begin{macrocode}

\DeclareOption{floatsnormalsize}{%
  \def\figuresetup{\normalsize}%
  \def\tablesetup{\normalsize}%
  }
%    \end{macrocode}
%
% 
% \subsection*{Kolejno informacji w tytule}
%    Te opcje steruj kolejnoci umieszczenia na karcie tytuowej
%    autora i tytuu publikacji.
%    \begin{macrocode}
\newif\if@authorfirst
\DeclareOption{authortitle}{\@authorfirsttrue}
\DeclareOption{titleauthor}{\@authorfirstfalse}
%    \end{macrocode}
% 
% \subsection*{Wciecia po tytuach}
%    \begin{macrocode}
\DeclareOption{indentfirst}{\@afterindenttrue}
\DeclareOption{noindentfirst}{\@afterindentfalse}
%    \end{macrocode}
%
% \subsection*{Opcje domylne}
%
%    Dla wszystkich klas domylny jest skad jednoamowy pismem
%    10-punktowym na papierze formatu A4.  Dla ksiki domylny jest
%    druk dwustronny.
%    \begin{macrocode}
%<*article>
\ExecuteOptions{a4paper,10pt,oneside,onecolumn,%

%
%    \begin{macrocode}

%  In this section we are finally dealing with the nasty typographical
%  details.
%
% \subsection{Stopnie pisma}
%
%    \LaTeX\ offers the user commands to change the size of the font,
%    relative to the `main' size. Each relative size changing command
%    |\size| executes the command
%    |\@setfontsize||\size|\meta{font-size}\meta{baselineskip} where:
%
%    \begin{description}
%    \item[\meta{font-size}] The absolute size of the font to use from
%        now on.
%
%    \item[\meta{baselineskip}] The normal value of |\baselineskip|
%        for the size of the font selected. (The actual value will be
%        |\baselinestretch| * \meta{baselineskip}.)
%    \end{description}
%
%    A number of commands, defined in the \LaTeX{} kernel, shorten the
%    following  definitions and are used throughout. They are:
% \begin{center}
% \begin{tabular}{ll@{\qquad}ll@{\qquad}ll}
%  \verb=\@vpt= & 5 & \verb=\@vipt= & 6 & \verb=\@viipt= & 7 \\
%  \verb=\@viiipt= & 8 & \verb=\@ixpt= & 9 & \verb=\@xpt= & 10 \\
%  \verb=\@xipt= & 10.95 & \verb=\@xiipt= & 12 & \verb=\@xivpt= & 14.4\\
%  ...
%  \end{tabular}
%  \end{center}
%
% \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
%    |\belowdisplayshortskip|.
%
%    \begin{macrocode}
%<*10pt|11pt|12pt>

%
% \begin{macro}{\headheight}
% \begin{macro}{\headsep}
% \begin{macro}{\topskip}
%    Warto \cs{headheight} --- wysoko paska przeznaczonego na
%    gwk strony --- ustalamy na jeden wiersz tekstu.  Midzy gwk
%    i amem stosujemy jeden wiersz odstpu (!!!mao?).  \cs{topskip}

% \end{macro}
%
% \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|. This is achieved by setting
%    it internally at |\begin{document}|. 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, therefore we set |\maxdepth| to half the value of
%    |\topskip|.

%
% \subsubsection{Rozmiary kolumny}
% \begin{macro}{\textwidth}
%    Szeroko kolumny wyznaczamy w~nastpujcy pokrtny sposb.

%
% \subsubsection{Marginesy}
%
%    Marginesy obliczamy na podstawie wartoci wyznaczonych
%    uprzednio. 
%
% \begin{macro}{\oddsidemargin}
% \begin{macro}{\evensidemargin}
%    Szeroko strony pomniejszamy o~szeroko kolumny, szeroko amu
%    na marginalia i~odstp od amu gwnego.  Wynik rozdzielamy rwno
%    na lewy i~prawy margines.
%    \begin{macrocode}
\setlength\@tempdima{\paperwidth}
\addtolength\@tempdima{-\textwidth}
\addtolength\@tempdima{-\marginparwidth}
\addtolength\@tempdima{-\marginparsep}
\divide\@tempdima by2
%    \end{macrocode}
%    Przy druku jednostronnym centrujemy kolumn (prawy margines rwny
%    lewemu).  Przy druku dwustronnym stosujemy proporcj wewntrznego
%    marginesu do zewntrznego jak 2:3 (czy to ,,adna'' warto?).
%    \begin{macrocode}
\setlength\oddsidemargin{\@tempdima}
\setlength\evensidemargin{\@tempdima}
\if@twoside
  \addtolength\oddsidemargin{-.1\@tempdima}
  \addtolength\evensidemargin{.1\@tempdima}
\fi
%    \end{macrocode}
%    Wreszcie zmniejszamy obliczone marginesy o~1~cal, poniewa dla

%
% \begin{macro}{\topmargin}
%    Margines grny obliczamy tak, aby kolumn wraz z~miejscem na

%
% \subsubsection{Przypisy}
%
% \begin{macro}{\footnotesep}
%    |\footnotesep| is the height of the strut placed at the beginning

%    da si zastosowa w~naszym przypadku, poniewa np. w~stylu
%    \pstyle{outer} pierwsze strony rozdziaw zachowuj ten styl.
%    Dlatego zastosowaem rozwizanie bardziej oglne, wprowadzajc
%    trzy rodzaje stylw.  Gdyby projektowa system stylw od pocztku,
%    naleaoby go tak zrealizowa, aby nie nakaday si pojcia.
%    Tutaj jednak aby unikn zbytnich ingerencji w kernel \LaTeX a
%    stosuj rozwizanie dziebko pokrtne.
%
%    Wprowadzone zostaj nastpujce style funkcjonalne, ktrych
%    definicja zmienia si w~zalenoci od wybranego stylu
%    ,,prawdziwego'': 
%    \begin{description}
%    \item[normal] uywany na wikszoci kolumn tekstowych,

%    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}}

% \begin{macro}{\maketitle}
%    Definicja \cs{maketitle} jest zalena od tego, czy tytu ma by
%    umieszczony na oddzielnej stronie.
%
%    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;
%    these changes affect all footnotes.
%    \begin{macrocode}

  }%
  \end{center}\par
%    \end{macrocode}
%    Then we call |\@thanks| to print the information that goes into
%    the footnote and finish the page.
%    \begin{macrocode}
  \vfill\vfill
  {\centering\normalsize \@date \par}
  \@thanks
  \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.

  \global\let\@title\@empty
%    \end{macrocode}
%    After the title is set the declaration commands |\title|, etc.\
%    can vanish.
%    The definition of |\and| makes only sense within the argument of
%    |\author| so this can go as well.
%    \begin{macrocode}

%    \end{macrocode}
%    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|.
%    \begin{macrocode}
\else
\newcommand\maketitle{\par
  \begingroup
    \renewcommand\thefootnote{\@fnsymbol\c@footnote}%
    \long\def\@makefntext##1{
        \parindent\@parindent
        \@textsuperscript{\normalfont\@thefnmark}\enspace##1}%
%    \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@   % Prevents figures from going at top of page.
      \@maketitle
    \fi
%    \end{macrocode}
%    This page gets a \pstyle{plain} layout. We call |\@thanks| to
%    produce the footnotes.
%    \begin{macrocode}
    \thispagestyle{opening}\@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.

%
%    |\roman{|\Lcount{COUNTER}|}| prints the value of

%
%    |\Roman{|\Lcount{COUNTER}|}| prints the value of

%
%    |\Alph{|\Lcount{COUNTER}|}| prints the value of \Lcount{COUNTER}

% \subsubsection{Parametry dotyczce wszystkich list}
%
% 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}{\leftmargini}
% \begin{macro}{\leftmarginii}
% \begin{macro}{\leftmarginiii}
% \begin{macro}{\leftmarginiv}
% \begin{macro}{\leftmarginv}
% \begin{macro}{\leftmarginvi}
% When we are in two column mode some of the margins are set somewhat
% smaller.
%    \begin{macrocode}
%<*article|report|book>
\setlength\leftmargini{1\parindent}
%    \end{macrocode}
%    Until the whole of the parameter setting in these files is
%    rationalised, we need to set the value of |\leftmargin| at this
%    outer level.
%    \begin{macrocode}
\leftmargin  \leftmargini
%    \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{macrocode}

% \begin{environment}{abstract}
%    When we are producing a separate titlepage we also put the

%    the page.
%
%    Note that this environment is not defined for books.

%    When we are not making a separate titlepage --the default for the

%
% \subsubsection{Titlepage}
%
% \begin{environment}{titlepage}
%  In the normal environments, the titlepage environment does nothing
%  but start and end a page, and inhibit page numbers.  In the report
%  style, it also resets the page number to one, and then sets it
%  back to one at the end.  
%  In two-column style, it still makes a 
%  one-column page.

%
% \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 the article document class the |\appendix| command must do the
%    following:
%    \begin{itemize}
%    \item reset the section and subsection counters to zero,
%    \item redefine |\thesection| to produce alphabetic appendix
%        numbers. This redefinition is done globally to ensure that it 
%        survives even if |\appendix| is issued within an environment such
%        as \texttt{multicols}.
%    \end{itemize}

%    \end{macrocode}
%
%    In the report and book document classes 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. This redefinition is done globally to ensure that it 
%        survives even if |\appendix| is issued within an environment such
%        as \texttt{multicols}.

%
% \subsection{Setting parameters for existing environments}
%
% \subsubsection{Array and tabular}
%
% \begin{macro}{\arraycolsep}
%    The columns in an array environment are separated by
%    2|\arraycolsep|.
%    \begin{macrocode}
\setlength\arraycolsep{5\p@}
%    \end{macrocode}
% \end{macro}

% \end{macro}
%
% \begin{macro}{\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. 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

%    \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}
%    When within chapters, the equation counter will be reset at
%    the beginning of a new chapter and the equation number will
%    be prefixed by the chapter number.
% \changes{v1.3u}{1996/10/31}{Added test for non-zero chapter number}
%
%    This code  must follow the |\chapter| definition or, more exactly,
%    the definition of the chapter counter.
%    \begin{macrocode}
%<article>\renewcommand \theequation {\@arabic\c@equation}
%<*report|book>

\renewcommand\theequation
  {\ifnum \c@chapter>\z@ \thechapter.\fi \@arabic\c@equation}
%</report|book>
%    \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 \emph{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 the report and book document classes figures within chapters are
%    numbered per chapter.

% \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 the report and book document classes tables within chapters are
%    numbered per chapter.

%    \end{macrocode}
% \end{environment}
% \end{environment}
%
% \subsubsection{Polecenie \sc{caption}}
%
%    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|.

% \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
%    |\DeclareTextFontCommand|, 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.

% \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 the |\@dottedtocline|
%    command, which works as follows.
%
%    |\@dottedtocline{|\meta{level}|}{|\meta{indent}|}{|^^A
%                      \meta{numwidth}|}{|^^A
%                      \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{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| $\ge$ |\@pnumwidth|
%    \item[\texttt{\bslash @dotsep}] Separation between dots, in mu

% \begin{macro}{\l@part}
%    Each sectioning command needs an additional macro  to format its
%    entry in the table of contents, as described above. The macro for
%    the entry for parts is defined in a special way.
%
%    First we make sure that if a pagebreak should occur, it occurs
%    \emph{before} this entry. Also a little whitespace is added and a
%    group begun to keep changes local.
%    \begin{macrocode}
\newcommand*\l@part[2]{%
  \ifnum \c@tocdepth >-2\relax
    \mw@tocskip{-1}{.6\baselineskip}%
    \begingroup
%    \end{macrocode}
%    We set |\parindent| to 0pt and use |\rightskip| to leave
%    enough room for the pagenumbers.\footnote{^^A
%        We should really set \cs{rightskip} to \cs{@tocrmarg} instead 
%        of \cs{@pnumwidth} (no version of {\LaTeX} ever did this), 
%        otherwise the \cs{rightskip} is too small.
%        Unfortunately this can't be changed in {\LaTeXe} as we don't 
%        want to create different versions of {\LaTeXe} which produce 
%        different typset output unless this is absolutely necessary;
%        instead we suspend it for \LaTeX3.}
%    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\normalsize

        }\par
%    \end{macrocode}
%    Prevent a pagebreak immediately after this entry, but use
%    |\everypar| to reset the |\if@nobreak| switch. Finally we close
%    the group.
%    \begin{macrocode}

%

%    \end{macrocode}
% \end{macro}
%
% \begin{environment}{thebibliography}
%    The `thebibliography' environment executes the following
%    commands:
%
%    |\renewcommand{\newblock}{\hskip.11em \@plus.33em \@minus.07em}|\\
%      --- Defines the ``closed'' format, where the blocks (major units
%      of information) of an entry run together.
%
%    |\sloppy|  --- Used because it's rather hard to do line breaks in
%      bibliographies,
%
%    |\sfcode`\.=1000\relax| ---
%      Causes a `.' (period) not to produce an end-of-sentence space.
%
%    The implementation of this environment is based on the generic
%    list environment. It uses the \Lcount{enumiv} counter internally
%    to generate the labels of the list.
%
%    When an empty `thebibliography' environment is found, a warning
%    is issued.

%  \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 separate paragraph. At
%    the user level the commands |\item|, |\subitem| and |\subsubitem|
%    are used to produce index entries of various levels. When a new
%    letter of the alphabet is encountered an amount of |\indexspace|
%    white space can be added.

%    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}
%          \newcommand\@makefntext[1]{%
%             \@setpar{\@@par
%                      \@tempdima = \hsize
%                      \advance\@tempdima-10pt
%                      \parshape \@ne 10pt \@tempdima}%
%             \par
%             \parindent 1em\noindent
%             \hbox to \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.
%
%    \begin{macrocode}
\newcommand\@makefntext[1]{%
    \parindent\@parindent
    \indent\@makefnmark\enspace#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|. We use
%    the default definition for it.
%    \begin{macrocode}
%\renewcommand\@makefnmark{\hbox{\@textsuperscript
%                                  {\normalfont\@thefnmark}}}
%    \end{macrocode}
% \end{macro}

% \subsection{Words}
%
% This document class is for documents prepared in the English language.
% To prepare a version for another language, various English words must
% be replaced.  All the English words that require replacement are
% defined below in command names. These commands may be redefined in
% any class or package that is customising \LaTeX\ for use with
% non-English languages.

%    This macro uses the \TeX\ primitives |\month|, |\day| and |\year|
%    to provide the date of the \LaTeX-run.
%
%    At |\begin{document}| this definition will be optimised
%    so that the names of all the `wrong' months are not stored.
%    This optimisation is not done here as that would `freeze'
%    |\today| in any special purpose format made by loading the class
%    file into the format file.
