\chapter{General Remarks}


\section{Introduction}

Originally the \script{Script} package was written by Frank Neukam for
\LaTeX~2.09. He wanted to implement European rules of typography and paper
formats as documented in \cite{JanTschichold}. The first version appeared in
June~1992 with great resonance.

Markus Kohm reimplemented version~2.0 from scratch for \LaTeXe\ (together
with its \LaTeX~2.09 compatibility mode) as a \package{docstrip} module.
Most of this documentation is taken directly from Frank Neukam's Guide to
\script{Script~2.0}\Index{Script 2.0} (in German). Please refer to the
German version of this documentation for compatibility questions concerning
the original \script{Script~2.0} package for \LaTeX.

\section{Compatibility Remarks}

All commands which are available in the standard classes are implemented
also in the \script{KOMA--Script} package. Additionally a few macros has been
added, and some of the original commands behave differently. Nevertheless it
should be possible to process any document with \script{KOMA--Script} which
has been written for the standard classes.

Table~\ref{TAB:Zuordnung} shows the relation between standard classes and
\script{KOMA--Script} classes.

\chapter{The New Layout}


\section{The New Fonts}

\begin{decl}|\sfb|\end{decl}%
\BeginIndex{Cmd}{sfb}%
All occurrences of Extended Boldface (i.e.\ captions, index, and
|description| environment) has been replaced with Sansserif Bold Extended
(|\sffamily\bfseries|). This is a font without serifs having semibold weight
which can be selected with the old font selection command |\sfb| or with the
new font commands |\sffamily\bfseries|. Note that the smallest available
size is 10pt, thus |\tiny\sfb| will select normal bold extended automatically.
\EndIndex{Cmd}{sfb}


\section{The Type Area}

\subsection{Fundamental Remarks}

The type area defines the size of the printed area of a page\footnote{not
counting headers, footers, and footnotes} and its exact position; the text
width depends on the selected font and font size (60--70 characters per line
give optimal readability).

Jan Tschichold suggests in \cite{JanTschichold} a simple algorithm to get
good--looking results even for `non--classical' paper formats like DIN~A4
(which is the default paper format for all \script{KOMA--Script} classes).
Type area and paper format have the same width/length ratios; even the
margins have simple proportions (inner margin/outer margin and upper
margin/lower margin respectively have the proportion 1:2; without the
|twoside| option inner and outer margin are equal).

\subsection{The Construction}

The construction is based on a devision of the width and height of a page in
$n$ equal parts which will be called HLU and VLU (horizontal/vertical length
unit).

\begin{description}
\item[Example: ] If we divide a DIN~A4 page (210 mm $\times$ 297 mm)
       in ten parts ($n=10$) we get a horizontal length unit
       HLU = 210~mm $\div$ 10 = 21~mm and a vertical length unit
       VLU = 297~mm $\div$ 10 = 29.7~mm.
\end{description}

\noindent Now we simply set in case of double sided printing the inner
margin\footnote{here we mean the \emph{visible} margin, not the margin
values taken from the |odd-| and |evensidemargin| registers; we will
evaluate these parameters to get the wanted visible margins.} to 1~HLU and
the outer margin to 2~HLU. In case of single page printing inner and outer
margin will be both 1.5~HLU. Analogously we set the upper margin to 1~VLU
and the lower margin to 2~VLU. Thus the text area will have $(n-3)$~HLU
width and $(n-3)$~VLU height. Marginal notes will be output in the outer
margin and limited to a width of 1.5~HLU for twosided and 1~HLU for onesided
printing.

\begin{description}
\item[Example: ] In case of dividing the page into 6~units ($n=6$) left and
        right margin together have 3~HLU, upper and lower margin have 3~VLU.
        Thus the text area is exactly half as wide and high as the entire
        page.
\end{description}

\noindent \TeX's demand that |\textwidth|\IndexCmd{textwidth} should be a
multiple of the \texttt{typewriter} character width will not be accomplished
with the above described algorithm. But even the original styles don't
follow this rule, and only text written entirely with \texttt{typewriter}
type will be affected. See section~\ref{AREASET} for a method how to adjust
the type area for |\tt| fonts.

The second rule of the type area construction, namely that |\textheight|
\IndexCmd{textheight} should equal |\topskip|\IndexCmd{topskip} plus an
integer multiple of |\baselineskip|\IndexCmd{baselineskip}, will be
fulfilled. This ensures that for pages completely filled with ordinary text
(i.e.\ pages without captions, tables, displayed material etc.) paragraphs
don't need to be stretched to assure that the lowest text line will align
with the lower margin of the text area. Thus the type area height will be at
most one line larger than the exact construction's value.

\subsection{Selection of the Type Area}

It's easy to see that for small $n$ the text area will be small too compared
to the page size, and that for large $n$ the text area fills the page almost
completely (it's hardly possible to output marginal notes correctly for $n$
values greater than 12). Modifying $n$ enables the user to change the size
of the type area within a great range having always the guarantee of an
optimal construction.

Optionally you can provide a binding correction \m{BCOR} which will be
taken into account while constructing the type area. The algorithm simply
reduces the page width by \m{BCOR}, computes the type area again and
finally increases the inner margin by \m{BCOR}.

\begin{description}
\item[Example: ] Assuming that a glue binding reduces the visible page width
        of 210~mm (ISO/DIN~A4) by an amount of 8~mm (see below how to
        specify \m{BCOR}) the new text proportion will be 202:297 instead
        of the original 210:297. Now for example the type area will be
        centered again on the visible part of the page for onesided
        printing.
\end{description}

\begin{decl}|\typearea|\oarg{BCOR}\arg{DIV}\end{decl}%
\BeginIndex{Cmd}{typearea}%
The command |\typearea| will compute the type area anew. Because internal
values like |\oddsidemargin| etc.\ will be changed, this command is only
allowed in the preamble (i.e.\ before |\begin{document}|). The optional
argument \m{BCOR} will adjust the binding correction, whereas \arg{DIV}
sets $n$ as described above. \m{BCOR} needs a valid \TeX\ measure unit
(pt, mm, cm, in, \dots); \m{DIV} must be an integer greater than~3.

Using \class{scrartcl}, \class{scrreprt}, or \class{scrbook} selects
\m{DIV} as described in table~\ref{DIV1} (without selecting a binding
correction) and calls |\typearea| automatically. They will do so by
inputting the package \package{typearea}\IndexPackage{typearea} which
contains the |\typearea| macro.

It's also possible to let \script{KOMA--Script} compute a good value for
\m{DIV}: if you choose one of the values 1 or 2 for \m{DIV} (which
would make no sense in the normal context), \script{KOMA--Script} tries to
find an appropriate type area assuming that an optimal legibility is given
if 69~characters per line are used; additionally too small margins are
avoided. A value 0 for \m{DIV} has a special meaning also: the predefined
default values for the given paper and font size are used. If no default
values exist, \script{KOMA--Script} will compute them. A value 3 for
\m{DIV} has a special meaning too: see \m{DIVclassic} below.

\begin{table}
\begin{center}
\DeleteShortVerb{\|}
\begin{tabular}{|c|c|}
\hline
text font size & {\m DIV} \\
\hline
10pt & 8 \\
11pt & 10 \\
12pt & 12 \\
\hline
\end{tabular}
\MakeShortVerb{\|}
\caption{\label{DIV1}\m{DIV} defaults}
\end{center}
\end{table}

You can use table~\ref{DIV2} as a starting point for selecting \m{DIV}
manually. The table values assume |a4paper| with twosided printing and
\m{BCOR} = 0~pt (without considering the adjustment between the height of
the text area and the font size dependent value of |\baselineskip| which can
increase the text area by at most 14.5~pt $\simeq$ 5.1~mm).

\begin{table}
\begin{center}
\DeleteShortVerb{\|}
\begin{tabular}{|c||c|c|c|c|}\hline
       & \multicolumn{2}{c|}{text area} & \multicolumn{2}{c|}{margins}\\
\m{DIV}& width [mm] & height [mm] & top [mm] & inner [mm] \\\hline
6  & 105.00 & 148.50 & 49.50 & 35.00 \\
7  & 120.00 & 169.71 & 42.43 & 30.00 \\
8  & 131.25 & 185.63 & 37.13 & 26.25 \\

10 & 147.00 & 207.90 & 29.70 & 21.00 \\
11 & 152.73 & 216.00 & 27.00 & 19.09 \\
12 & 157.50 & 222.75 & 24.75 & 17.50 \\
13 & 161.54 & 228.46 & 22.85 & 16.15 \\
14 & 165.00 & 233.36 & 21.21 & 15.00 \\
15 & 168.00 & 237.60 & 19.80 & 14.00 \\\hline
\end{tabular}
\MakeShortVerb{\|}
\caption{\label{DIV2}Type area values in relation to \m{DIV}}
\end{center}
\end{table}

\begin{decl}|DIV|\m{factor}\\|BCOR|\m{correction}\end{decl}%
\BeginIndex{Option}{DIV}\BeginIndex{Option}{BCOR}%
It is also possible to pass through the type area parameters \m{DIV} and
\m{BCOR} as options to the classes \class{scrartcl}, \class{scrreprt}, and
\class{scrbook} to the package \package{typearea}; then it's not necessary
to call |\typearea| explicitly. \m{factor} and \m{correction} should follow
the option directly.

Here a small example:
\begin{quote}\begin{small}\begin{verbatim}
  \documentclass[DIV14,BCOR0.5cm]{scrreprt}
\end{verbatim}\end{small}\end{quote}

Also you can use the option |DIVcalc| to let \script{KOMA--Script}
calculate \m{DIV} values automatically (this is similar to |DIV0| provided
no default values are given).

Finally you can use the option |DIVclassic| to let \script{KOMA-Script}
calculate \m{DIV} for ``sp{\"a}tmittelalterlichen Buchseitenkanon''. At the
resulting typearea textheight is almost equal to paperwidth. Fontsize and
linewidth (number of characters per line) are not considered, so typearea may
be as awful as can be.
\EndIndex{Option}{DIV}\EndIndex{Option}{BCOR}
\EndIndex{Cmd}{typearea}

\subsection{Uncommon Type Areas\label{AREASET}}

\begin{decl}|\areaset|\oarg{BCOR}\arg{WIDTH}\arg{HEIGHT}\end{decl}%
\BeginIndex{Cmd}{areaset}%
To construct type areas with uncommon proportions or to specify type areas
which have \emph{exactly} the values of the previous table (without
adjusting to an integer multiple of |\baselineskip|) it's also possible to
use |\areaset| instead of |\typearea|\IndexCmd{typearea}. |\areaset| sets
the text width to \arg{WIDTH} and the text height to \m{HEIGHT} (without
any additional corrections) and computes the margins in a similar way as the
|\typearea| command. The optional argument \m{BCOR} will be handled as
described above.

Now we can easily construct type areas which are exactly quadratic or very
narrow and high. If you don't like the positioning chosen by |\areaset|,
it's of course possible to change the margins afterwards.

Here is the example which shows how to adjust the text area having exactly
a width of 30 characters in \texttt{typewriter} type:

\begin{quote}\begin{small}\begin{verbatim}
\newlength{\thirtytt}
\settowidth{\thirtytt}{\texttt{123456789012345678901234567890}}
\areaset{\thirtytt}{20cm} % text height: 20cm
\end{verbatim}\end{small}\end{quote}

\noindent |\areaset| is only allowed in the preamble.
\EndIndex{Cmd}{areaset}

\subsection{Including Headers and Footers}

Sometimes it makes sense to assume that the header and/or the footer line
are part of the text area while computing the type area, as shown in this
documentation. Here we have a horizontal line which separates the header
from the text body, thus moving the header optically nearer.

\begin{decl}|headinclude|\\|headexclude|\end{decl}%
\BeginIndex{Option}{headinclude}\BeginIndex{Option}{headexclude}%
If you switch on the |headinclude| option the commands
|\typearea|\IndexCmd{typearea} and |\areaset|\IndexCmd{areaset} will include
the header line to compute the type area. The opposite option is
|headexclude|.
\EndIndex{Option}{headinclude}\EndIndex{Option}{headexclude}

\begin{decl}|footinclude|\\|footexclude|\end{decl}%
\BeginIndex{Option}{footinclude}\BeginIndex{Option}{footexclude}%
These are the analogous options for including and excluding the footer line.
\EndIndex{Option}{footinclude}\EndIndex{Option}{footexclude}

You can specify the options directly in the |\documentclass| macro which is
easiest. If you specify the options in the |\usepackage| macros, don't
forget to load the \package{typearea} package\IndexPackage{typearea}
explicitly.

\subsection{Different Paper Formats}

As with the standard classes it is possible to select different paper
formats using the options |a3paper|, |landscape| etc. Contrary to the
original classes the computation of the type area will be done implicitly by
calling the |typearea| package using the above described rules.

To select a paper format which is not defined in the \package{typearea}
package\IndexPackage{typearea} you can choose between two possibilities.
Either you change |\paperwidth|\IndexCmd{paperwidth} and
|\paperheight|\IndexCmd{paperheight} manually and call then the
|\typearea|\IndexCmd{typearea} command (or |\areaset|\IndexCmd{areaset}), or
you create additional options and write them into a file
\file{typearea.cfg}\index{typeareacfg=\file{typearea.cfg}}. Such defined
options can be used similar to standard options.

\begin{decl}|\SetDIVList|\arg{list}\end{decl}%
\BeginIndex{Cmd}{SetDIVList}%
Besides the paper size it is generally possible to define font size
dependent \m{DIV} factors. The command |\SetDIVList| creates such a list
which contains a \m{DIV} value (in braces) for each font size, starting
with 10~pt, followed by the value for 11~pt, then 12~pt and so forth. Not
defining a list with |\SetDivList| is equal to |\SetDIVList{{8}{10}{12}}|.
If you select a font size without a value in this list, the default value~10
will be used.

\begin{description}
\item[Example 1: ] A poem booklet should be printed on ISO/DIN A5 paper. It
        is sufficient to select the |a5paper| option:
        \begin{quote}\begin{small}
        |\documentclass[a5paper]{scrreprt}|
        \end{small}\end{quote}
\item[Example 2: ] The text area of a schedule using \emph{landscape}
        ISO/DIN A4 paper should be exactly 270~mm $\times$ 190~mm. The
        following code implements this:
        \begin{quote}\begin{small}
        |\documentclass[a4paper]{scrreprt}|\\
        |\areaset{270mm}{190mm}|
        \end{small}\end{quote}
        Additionally you need a (system dependent) command forcing the
        printer driver to use landscape format.
\item[Example 3: ] The poem booklet of example~1 will now have a binding
        correction of 1.5~mm, and the type area should be a bit larger:
        \begin{quote}\begin{small}
        |\documentclass[a5paper,DIV12,BCOR1.5mm]{scrreprt}|
        \end{small}\end{quote}
\item[Example 4: ] We want to use endless paper with the dimensions
        $8\frac{1}{4}$~in $\times$ 12~in. To have a good--looking type area
        we could say
        \begin{quote}\begin{small}
        |\paperwidth 8.25in|\\
        |\paperheight 12in|\\
        |\typearea{10}|
        \end{small}\end{quote}
        which is best to be written as a new option into
        \file{typearea.cfg}\index{typeareacfg=\file{typearea.cfg}}; assuming
        that the name of this option is `endless' we can now simply say
        \begin{quote}\begin{small}
        |\documentclass[endless]{scrreprt}|
        \end{small}\end{quote}
        Here a complete example of an entry in \file{typearea.cfg}:
        \begin{quote}\begin{small}
        |\DeclareOption{endless}|\\
        |  {\setlength\paperheight {8.25in}%|\\
        |   \setlength\paperwidth  {12in}%|\\
        |   \SetDIVList{{8}{10}{12}}}|
        \end{small}\end{quote}
\end{description}
\EndIndex{Cmd}{SetDIVList}

Note that you can also use the \package{typearea}
package\IndexPackage{typearea} together with the standard classes; however
it is \emph{not} a good idea to use \package{typearea} package with the
\class{scrlettr} letter class which has a special, fixed type area (this
class is only documented in the German version of this documentation).


\section{Additional Changes}

\subsection{Default Fontsize}

Without specifying a different default fontsize explicitly in the
|\documentclass| command 11~pt fonts will be used as the default (as shown
in this documentation) for all classes except \class{scrlettr} (which uses
12~pt). The \LaTeXe\ standard classes use 10~pt fonts.

\subsection{Chapter Headings and Enumeration}

Chapter headings of the classes \class{scrbook} and \class{scrreprt} will be
typeset without a separate line for the word ``chapter'' (as implemented in
\class{book} and \class{report}; \script{KOMA--Script} classes don't use this
word), instead the chapter number will directly precede the caption text. To
have a distinct separation between chapters and the appendix (which now only
differs in the style of enumeration) it is highly recommended to insert
|\part*{Appendix}| between the last chapter and the appendix.

\begin{decl}|bigheadings|\\|normalheadings|\\|smallheadings|\end{decl}%
\BeginIndex{Option}{bigheadings}%
\BeginIndex{Option}{normalheadings}%
\BeginIndex{Option}{smallheadings}%
Some people prefer smaller headings. Use one of the above three options to
change the size; \script{KOMA--Script} uses |bigheadings| as the default.
\EndIndex{Option}{smallheadings}
\EndIndex{Option}{normalheadings}
\EndIndex{Option}{bigheadings}

\begin{decl}|\raggedsection|\end{decl}%
\BeginIndex{Cmd}{raggedsection}%
Starting with version~2.2h no hyphenation will be used in headings. If
you want to allow hyphenation you should write
\begin{quote}\begin{verbatim}
\let\raggedsection\relax
\end{verbatim}\end{quote}
Usually |\raggedsection| is identical to
|\raggedright|\IndexCmd{raggedright}.
\EndIndex{Cmd}{raggedsection}

\begin{decl}|pointednumbers|\\|pointlessnumbers|\end{decl}%
\BeginIndex{Option}{pointednumbers}%
\BeginIndex{Option}{pointlessnumbers}%
Starting with version~2.2c no final dot will be used after ordinary section
numbers if you use Arabic numbers (e.g. 1, 1.1, 1.2.3 etc., see
\cite[p.~18, rule~5]{Duden}). If you use Roman numerals or letters also, a
final dot will be used (e.g. I., I.1., A., A.1.1 etc, see
\cite[p.~18, rule~6]{Duden}).

This behaviour can be controlled with |pointednumbers| and
|pointlessnumbers|: the former option will always force and the latter will
always suppress a final dot. Note that the opposite of |pointednumbers| is
\emph{not} |pointlessnumbers|!
\EndIndex{Option}{pointlessnumbers}
\EndIndex{Option}{pointednumbers}

Currently you have to run \LaTeX\ twice to assure correct behaviour of the
final dot.

\subsection{Headings and Page Numbers}

The \class{srcbook} class uses |headings| as the default page style;
\class{scrreprt} and \class{scrartcl} have |plain| as the default.

If you use the option |twoside|, page numbers will be set into the outer
margins; otherwise they will be centered. \class{scrbook} has |twoside| as
the default.

In contrast to the standard classes headings will not be set in uppercase,
and the default font will be \textsl{slanted} (was \textit{italics}).
Chapter headings will not use the word ``CHAPTER'', and the page number is
always in the footer (which would be empty otherwise). An advantage of these
changes is the possibility to have much longer chapter headings without
truncation.

\begin{decl}|headsepline|\\|headnosepline|\\
            |footsepline|\\|footnosepline|\end{decl}%
\BeginIndex{Option}{headsepline}\BeginIndex{Option}{headnosepline}%
\BeginIndex{Option}{footsepline}\BeginIndex{Option}{footnosepline}%
To have a horizontal line below the header line\label{HEADSEPLINE} use the
class option |headsepline| to turn it on (|headnosepline| to turn it off).
This only works for the page styles |headings| and |myheadings| since
|plain| has no header line; |headsepline| automatically activates
|headinclude| (and similarly |headnosepline| sets |headexclude|). Default
for \class{scrbook}, \class{scrreprt} and \class{scrartcl} is
|headnosepline|.

The analogous options for footers are |footinclude|, |footexclude|,
|footsepline|, and |footnosepline|. This also works for the |plain| page
style.

\begin{description}
\item[Example: ] In the documentation you are just reading we have
    \begin{quote}\begin{small}
    |\documentclass[headsepline]{...}|
    \end{small}\end{quote}%
    to get a horizontal line below the page headers (this also activates
    |headinclude|).
\end{description}
\EndIndex{Option}{headsepline}\EndIndex{Option}{headnosepline}
\EndIndex{Option}{footsepline}\EndIndex{Option}{footnosepline}

\subsection{Some Additional Cosmetic Changes}

A small horizontal region (1~em) is reserved for the footnote number alone,
i.e.\ the footnote text always starts with this offset from the left margin.
In multiline footnotes the following lines will be indented 0.5~em again to
improve reading.

Paragraphs will be output without vertical space, being indented 1~em (this
is 1~|\quad|).

|\frenchspacing|\IndexCmd{frenchspacing} will be activated in spite of the
fact that the \package{german}\IndexPackage{german} package starting with
version~2.4 activates it too. This is subject to change.

The second level of the |enumerate|\IndexEnv{enumerate} environment will be
`a)' instead of `(a)'; the third level of the
|itemize|\IndexEnv{itemize} environment is now `$\triangleright$' instead
of `$\ast$'.

Author and date entries in titles will not be |\large| but |\Large|.

Multiline captions (as they can happen in |table|\IndexEnv{table} or
|figure|\IndexEnv{figure} environments) will be indented so that
``Figure~\dots:'' corresponds to a hanging indentation of that length.

There are many further changes which will be hardly noticed, e.g.\ the space
between the columns in |twocolumn| mode has been enlarged to 1~cc (1~Cicero
$\simeq$ 12~pt). Compare the \file{.dtx}--files of the original and the
\script{Script} classes if you interested in details.



\chapter{Additional Commands}


\section{Enhancements of Abstract and Titlepage}

\begin{decl}|abstractoff|\\|abstracton|\end{decl}%
\BeginIndex{Option}{abstractoff}\BeginIndex{Option}{abstracton}%
You can suppress the `Abstract' header with the option |abstractoff|; this
is the default for \class{scrartcl} and \class{scrreprt}. \class{scrbook}
has no abstract. The opposite option is |abstracton|.
\EndIndex{Option}{abstractoff}\EndIndex{Option}{abstracton}

\begin{decl}|\extratitle|\arg{extratitle}\\
            |\titlehead|\arg{text}\\
            |\subject|\arg{text}\\
            |\publishers|\arg{publisher}\\
            |\uppertitleback|\arg{text}\\
            |\lowertitleback|\arg{text}\\
            |\dedication|\arg{dedication}\end{decl}%
\BeginIndex{Cmd}{maketitle}%
\BeginIndex{Cmd}{extratitle}\BeginIndex{Cmd}{titlehead}%
\BeginIndex{Cmd}{subject}\BeginIndex{Cmd}{publishers}%
\BeginIndex{Cmd}{uppertitleback}\BeginIndex{Cmd}{lowertitleback}%
\BeginIndex{Cmd}{dedication}%
The following commands enhance |\maketitle| of the \script{Script} main
classes:

\begin{itemize}
    \item |\extratitle|
    creates a separate page with the extratitle\footnote{In former times the
    hard cover was sometimes missing; thus the very first page, the
    extratitle, protected the book so that it didn't become dirty. Today it
    will be frequently used as an extrapage before the main title to hold
    the publisher's name, the ISDN number etc.} on it. It will be printed as
    normal text by default, and the user has completely freedom to
    customize. The backside (even if twoside printing is on) is always
    empty.

    \item |\titlehead|
    prints some additional information in the head part of the main title
    page, e.g.\ an address of an institute.

    \item |\subject|
    prints directly above the main title an additional subject (e.g.\
    ``dissertation'') in a somewhat larger font.

    \item |\publishers|
    creates the publisher's name in the lower part of the main title page.

    \item If twosided printing is activated it is possible to write some
    information on the back page of the title page which would be otherwise
    empty. |\uppertitleback| and |\lowertitleback| print text near the upper
    and lower margin respectively (cf.\ the ``Haftungsausschlu\ss'' in this
    documentation).

    \item |\dedication|
    creates an own dedication page, with \emph{dedication} centered and with
    a slightly larger font. The back page is always empty.
\end{itemize}

\begin{description}
\item[Example: ] \
\begin{quote}\begin{small}\begin{verbatim}
\titlehead{Institute for Sinology \hfill SS1993
           \\12 University Street
           \\Unitown 3456}
\subject{Dissertation}
\title{About Chinese Food}
\author{Wun Tun}
\lowertitleback{This paper was created with the
                text formatting system \TeX.}
\maketitle
\end{verbatim}\end{small}\end{quote}
\end{description}
\EndIndex{Cmd}{extratitle}\EndIndex{Cmd}{titlehead}
\EndIndex{Cmd}{subject}\EndIndex{Cmd}{publishers}
\EndIndex{Cmd}{uppertitleback}\EndIndex{Cmd}{lowertitleback}
\EndIndex{Cmd}{dedication}

\noindent Usually the title starts on page~1. With an optional argument
(e.g.\ |\maketitle[-1]|) it's possible to adjust the starting page number.
\EndIndex{Cmd}{maketitle}


\section{Table of Contents}

Starting with version~2.3h some additional options are available to
change the appearance of the table of contents.

\begin{decl}|liststotoc|\end{decl}%
\BeginIndex{Option}{liststotoc}%
Usually there is no entry for the lists of figures and lists of tables in
the table of contents. Specifying the option |liststotoc| changes this to
get an entry (without a number).
\EndIndex{Option}{liststotoc}

\begin{decl}|bibtotoc|\\|bibtotocnumbered|\end{decl}%
\BeginIndex{Option}{bibtotoc}\BeginIndex{Option}{bibtotocnumbered}%
|bibtotoc| is similar to |liststotoc|. |bibtotocnumbered| will additionally
treat the bibliography as an own chapter having a number.
\EndIndex{Option}{bibtotocnumbered}\EndIndex{Option}{bibtotoc}

\begin{decl}|idxtotoc|\end{decl}%
\BeginIndex{Option}{idxtotoc}%
Similar to |bibtotoc|, but will never be an own chapter. The entry in the
table of contents should only indicate that an index exists.
\EndIndex{Option}{idxtotoc}


\section{The ``\texttt{\char92 xxxxfont}'' Variables\label{SECTFONT}}

\begin{decl}|\capfont|\\|\caplabelfont|\\
            |\descfont|\\|\headfont|\\
            |\pnumfont|\\|\sectfont|\end{decl}%
\BeginIndex{Cmd}{capfont}\BeginIndex{Cmd}{caplabelfont}%
\BeginIndex{Cmd}{descfont}\BeginIndex{Cmd}{headfont}%
\BeginIndex{Cmd}{pnumfont}\BeginIndex{Cmd}{sectfont}%
Starting with version~2.0 of the \script{Script} package a bunch of
variables to control the global font changes for column titles, pagination,
captions, headers and the |description| environment are implemented. This
enables the user to change e.g.\ the header font from |\sffamily\bfseries|
to |\rmfamily| with only one command---it's only necessary to write
|\renewcommand{\sectfont}{\rmfamily}| (usually in the preamble). In a
similar way all other fonts can be changed as shown in table
\ref{TAB::Fonts}. Changes of the font size are of course also possible
within the above commands.

\begin{table}
\begin{center}\small
\begin{tabular}{lll}
variable          & affected area     & default       \\\hline
|\capfont|        & caption texts     & |\normalfont| \\
|\caplabelfont|   & caption labels    & |\normalfont| \\
|\descfont|       & item texts of the {\tt description} environment
                                      & |\sffamily\bfseries| \\
|\headfont|       & column titles     & |\slshape|    \\
|\pnumfont|       & pagination        & |\normalfont| \\
|\sectfont|       & all headers and titles
                                      & |\sffamily\bfseries|   \\
\end{tabular}
\caption{\label{TAB::Fonts}%
        Commands to adjust fonts, its meaning and default values}
\end{center}
\end{table}
\EndIndex{Cmd}{capfont}\EndIndex{Cmd}{caplabelfont}
\EndIndex{Cmd}{descfont}\EndIndex{Cmd}{headfont}
\EndIndex{Cmd}{pnumfont}\EndIndex{Cmd}{sectfont}


\section{The Marginline}

\begin{decl}|\marginline|\arg{text}\end{decl}%
\BeginIndex{Cmd}{marginline}%
This command is the oneline analogon to the multiline
|\marginpar|\IndexCmd{marginpar} macro. It has the advantage that in
|twoside| mode on left pages the margin text will be aligned with the outer
text margin (i.e.\ flush right), contrary to |\marginpar| which treats the
line as the start of a paragraph, thus printing the text flush left in the
margin. Use this command for cross references and similar text snippets.
\EndIndex{Cmd}{marginline}


\section{The \texttt{\char92 addchap} and \texttt{\char92 addsec} Command}

\begin{decl}|\addchap|\oarg{index entry}\arg{header}\\
            |\addchap*|\arg{header}\\
            |\addsec|\oarg{index entry}\arg{header}\\
            |\addsec*|\arg{header}\end{decl}%
\BeginIndex{Cmd}{addchap}\BeginIndex{Cmd}{addchap*}%
\BeginIndex{Cmd}{addsec}\BeginIndex{Cmd}{addsec*}%
To create an unnumbered section like a preface or a greeting you only could
use the |\chapter*| or |\section*| command of the standard classes. But they
neither create an index entry nor a running head which you must add manually
if you want them which is not in the sense of the \LaTeX\ philosophy.

Thus the \script{Script} package offers the new commands |\addchap| and
|\addchap*| (for \class{scrbook} and \class{scrreprt}) together with
|\addsec| and |\addsec*| (for \class{scrartcl}) which behaves like
|\chapter| and |\section| except the missing enumeration. The starred
commands are very similar to the starred original commands with the
difference that running heads will be cleared additionally. As with the
original commands you can create index entries different from the header
with an optional argument.
\EndIndex{Cmd}{addchap}\EndIndex{Cmd}{addchap*}
\EndIndex{Cmd}{addsec}\EndIndex{Cmd}{addsec*}


\section{The \texttt{\char92 minisec} Command}

\BeginIndex{Cmd}{minisec}%
\begin{decl}|\minisec|\arg{Header}\end{decl}%
Sometimes it is desirable to have a kind of header which is connected to the
surrounding text without too great vertical spaces.

\minisec{Appearance of the new \texttt{\char92 minisec} command:}
The command |\minisec| (``mini section'') will do this job; the argument
will be printed with |\sffamily\bfseries|, and a vertical space of 1.5~ex
will be added before the header (and none after). Mini sections produce no
entry in the index.
\EndIndex{Cmd}{minisec}


\section{The \texttt{labeling} Environment}

\begin{decl}|\begin{labeling}|\oarg{separator}\arg{longest title}\\
            |\item|\oarg{title} \ldots \\
            |   |\vdots \\
            |\end{labeling}|\end{decl}%
\BeginIndex{Env}{labeling}%
\begin{labeling}{Appearance:}
\item[Appearance:] As you can see here in an example for the |labeling|
    environment, text will be printed like an ordinary paragraph but will
    have a title in front of it (here: ``Appearance'').

    The text is not restricted to one paragraph.

\item[Syntax:] |labeling| is an ordinary environment with one parameter and
    an optional argument. \m{longest title} is the longest argument
    including all font change commands. If you don't need a separator you
    can omit the optional argument \m{separator}.
\item[Example:] The |labeling| environment you are just reading starts with
    \begin{quote}\begin{small}\begin{verbatim}
\begin{labeling}{Appearance:}
\item[Appearance:] As you can see here in an example for the
    |labeling| environment, ...
\item[Syntax:] |labeling| is an ordinary...
    .
    .
\end{labeling}
       \end{verbatim}\end{small}\end{quote}
\end{labeling}
\EndIndex{Env}{labeling}



\chapter{Internationalization}
\Index[(]{CJK}

In cooperation with Werner Lemberg (|a7971428@unet.univie.ac.at|) the language
interface of the standard classes has been modified in a compatible way to
support languages which do not follow English grammatical or syntactical
rules. Even in English not all possibilities of labeling e.g.\ a figure are
supported: cf. ``Figure~1'' (supported) and ``First Figure'' (not
supported).\footnote{With `not supported' it is meant that you must do
tricky things or even modify some of the user invisible low level macros to
achieve the wanted results.} Additionally some languages will suppress
spaces between the running number and the |\figurename| or set them
differently.

Three modification levels have been introduced starting with
\script{KOMA--Script} version~2.2c (dated 25--May--1995) to gain a great
flexibility without loosing simplicity.

Level~1 are the standard macros like |\figurename| as defined in the
standard classes. |german.sty|, as an example, redefines this bunch of names
with German equivalents. Related to these macros are the font changing
commands |\sectfont| and its relatives.

Level~2 is the modification of the counters itself (e.g.\ |\thesection|
could use Chinese characters instead of Arabic numbers).

Level~3 finally allows for complete control over the ordering of counters,
titles, and spaces. It consists of the commands |\chaptermarkformat|,
|\sectionmarkformat|, |\subsectionmarkformat|, |\partformat|,
|\chapterformat|, |\figureformat|, |\table|\-|for|\-|mat|, and
|\captionformat|.

Here a simplified example for a Chinese |\part| command (Chinese characters
have been replaced with a transcription):

    \begin{quote}\begin{small}\begin{verbatim}
\newcommand\prepartname{di}
\newcommand\postpartname{bu}
\renewcommand\partformat{\prepartname~\thepart~\postpartname}
    \end{verbatim}\end{small}\end{quote}

It must be stated that some of the new features are not used within the
\script{Script} package by default since most sectioning commands don't use
|\chaptername| etc. The letter class |scrlettr.cls| doesn't accept the
|\...format| commands; |scrpage.cls| does (see section \ref{SCRPAGE}).

\chapter{The \texttt{scrpage} Package}\label{SCRPAGE}
\BeginIndex{Package}{scrpage}

The \package{scrpage} package defines a new interface to make the page
layout much more flexible to define as it would be with |\pagestyle|. It has
some similarities with the \package{fancyheadings}
package~\cite{fancyheadings} but tries new solutions of old problems. As an
example, there is a simple interface for the novice and a more sophisticated
one for the experienced user.

\package{scrpage} works with the standard \LaTeX\ classes also.


\section{The Simple Interface}

\begin{decl}|\headfont|\\|\pnumfont|\end{decl}%
\BeginIndex{Cmd}{headfont}\BeginIndex{Cmd}{pnumfont}%
|\headfont| selects the font for the headers and footers, |\pnumfont|
selects the page number font. Default definition for both commands is
|\normalfont|. Here an example of use:

    \begin{quote}
    |\renewcommand{\headfont}{\normalfont\slshape}|
    \end{quote}
\EndIndex{Cmd}{headfont}\EndIndex{Cmd}{pnumfont}

\begin{decl}|\headmark|\end{decl}%
\BeginIndex{Cmd}{headmark}%
If you choose the layout option |twoside|, |\headmark| is equivalent to the
\LaTeX\ commands |\leftmark| on even pages and |\rightmark| on odd pages. If
you select onesided printing, |\headmark| is always the same as
|\rightmark|. Thus the \package{scrpage} package itself controls whether we
are on a even or odd page; |\headmark| always contains the actual header
line.
\EndIndex{Cmd}{headmark}

\begin{decl}|\pagemark|\end{decl}%
\BeginIndex{Cmd}{pagemark}%
|\pagemark| contains the actual page number string. It will also select the
correct font (using |\pnumfont|), contrary to the standard \LaTeX\ command
|\thepage|.
\EndIndex{Cmd}{pagemark}

\begin{decl}|\deftripstyle|\arg{name}\oarg{olw}\oarg{ilw}\\
            |             | \arg{headleft}\arg{headmid}\arg{headright}\\
            |             | \arg{footleft}\arg{footmid}\arg{footright}%
\end{decl}%
\BeginIndex{Cmd}{deftribstyle}%
Use this command to define a new page layout with the name \m{name}. The
arguments \m{headleft}, \m{headmid}, \m{headright}, \m{footleft},
\m{footmid}, and \m{footright} will appear on the following places:

\begin{center}\setlength{\unitlength}{1mm}\begin{picture}(120,82)
\put(0,0){\dashbox{2}(58,82){~}}
\put(1,78){\makebox(0,0)[l]{\m{headright}}}
\put(29,78){\makebox(0,0){\m{headmid}}}
\put(57,78){\makebox(0,0)[r]{\m{headleft}}}
\put(29,41){\makebox(0,0){left page}}
\put(1,3){\makebox(0,0)[l]{\m{footright}}}
\put(29,3){\makebox(0,0){\m{footmid}}}
\put(57,3){\makebox(0,0)[r]{\m{footleft}}}
\put(60,0){\dashbox{2}(58,82){~}}
\put(61,78){\makebox(0,0)[l]{\m{headleft}}}
\put(89,78){\makebox(0,0){\m{headmid}}}
\put(117,78){\makebox(0,0)[r]{\m{headright}}}
\put(89,41){\makebox(0,0){right page}}
\put(61,3){\makebox(0,0)[l]{\m{footleft}}}
\put(89,3){\makebox(0,0){\m{footmid}}}
\put(117,3){\makebox(0,0)[r]{\m{footright}}}
\end{picture}\end{center}

To create separation lines for the header and the footer respectively use
the optional parameters \m{ilw} (inner line width) and \m{olw} (outer line
width); if only one optional argument is given \m{ilw} is set (similar to
class option |headsepline|). The values of the parameters are the line
thicknesses. Here an example with \m{olw}=2~pt, \m{ilw}=0.5~pt:

\begin{center}\setlength{\unitlength}{1mm}\begin{picture}(120,82)
\put(0,0){\dashbox{2}(58,82){~}}
\put(1,80){\rule{56\unitlength}{2pt}}
\put(1,78){\makebox(0,0)[l]{\m{headright}}}
\put(29,78){\makebox(0,0){\m{headmid}}}
\put(57,78){\makebox(0,0)[r]{\m{headleft}}}
\put(1,76){\rule{56\unitlength}{0.5pt}}
\put(29,41){\makebox(0,0){left page}}
\put(1,5){\rule{56\unitlength}{0.5pt}}
\put(1,3){\makebox(0,0)[l]{\m{footright}}}
\put(29,3){\makebox(0,0){\m{footmid}}}
\put(57,3){\makebox(0,0)[r]{\m{footleft}}}
\put(1,1){\rule{56\unitlength}{2pt}}
\put(60,0){\dashbox{2}(58,82){~}}
\put(61,80){\rule{56\unitlength}{2pt}}
\put(61,78){\makebox(0,0)[l]{\m{headleft}}}
\put(89,78){\makebox(0,0){\m{headmid}}}
\put(117,78){\makebox(0,0)[r]{\m{headright}}}
\put(61,76){\rule{56\unitlength}{0.5pt}}
\put(89,41){\makebox(0,0){right page}}
\put(61,5){\rule{56\unitlength}{0.5pt}}
\put(61,3){\makebox(0,0)[l]{\m{footleft}}}
\put(89,3){\makebox(0,0){\m{footmid}}}
\put(117,3){\makebox(0,0)[r]{\m{footright}}}
\put(61,1){\rule{56\unitlength}{2pt}}
\end{picture}\end{center}

A newly defined or redefined page style will be only active after a
|\pagestyle| or |\thispagestyle| command.
\EndIndex{Cmd}{deftribstyle}

To redefine the |myheadings| page style you should use the following macro:

\begin{decl}|\deftripstyle*|\arg{name}\oarg{olw}\oarg{ilw}\\
            |              | \arg{headleft}\arg{headmid}\arg{headright}\\
            |              | \arg{footleft}\arg{footmid}\arg{footright}%
\end{decl}%
\BeginIndex{Cmd}{deftribstyle*}%
This command creates a \emph{my} version of a page style. The difference to
the unstarred form is that sectioning commands like |\chapter| will not
alter the page headings; only |\markleft|, |\markright| and |\markboth| will
do that.
\EndIndex{Cmd}{deftribstyle*}

\section{The Experts' Interface}

\begin{decl}|\defpagestyle|\arg{name}\arg{header definition}\arg{footer definition}\\
            |\newpagestyle|\arg{name}\arg{header definition}\arg{footer definition}\\
            |\renewpagestyle|\arg{name}\arg{header definition}\arg{footer definition}\\
            |\providepagestyle|\arg{name}\arg{header definition}\arg{footer definition}\end{decl}%
\BeginIndex{Cmd}{defpagestyle}\BeginIndex{Cmd}{newpagestyle}%
\BeginIndex{Cmd}{renewpagestyle}\BeginIndex{Cmd}{providepagestyle}%
All these commands define a new page style with the following structure of
the header and footer definition:
\begin{quote}
\parg{ull,ulw}\arg{evenpage}\arg{oddpage}\arg{onepage}\parg{lll,llw}
\end{quote}
\m{ulw} and \m{llw} are the widths of the upper and the lower line of the
header or footer respectively, \m{ull} and \m{lll} are the lengths of the
upper and lower line (|\deftripstyle| and |\defstripstyle*| always use
|\textwidth| as the length thus these parameters are omitted). \m{evenpage}
and \m{oddpage} define the corresponding headers or footers and will be used
if twosided output is selected, \m{onepage} will be used for onesided
output.

The various flavours of the commands are similar to the variants of the
|\newcommand| macro: |\defpagestyle| will create the page style \m{name} and
overwrites an existing page style of this name without warning,
|\newpagestyle| outputs a warning if a page style with this name already
exists, |\renewpagestyle| will do the opposite, i.e.\ outputs a warning if a
page style with this name does not already exist, and |\providepagestyle|
defines only a new page style if no page style with this name has been
defined before (it will issue an entry in the log file if \m{name} already
exists).

Finally an example which was used to realize the header and footer lines of
this chapter:

\begin{small}\begin{verbatim}
\renewpagestyle{plain}{(\textwidth,0pt)%         header line
                       {\hfill}%
                       {\hfill}%
                       {\hfill}%
                       (\textwidth,0pt)}%
                      {(\textwidth,.4pt)%        footer line
                       {\pagemark\hfill}%
                       {\hfill\pagemark}%
                       {\hfill\pagemark\hfill}%
                       (\textwidth,1pt)}
\renewpagestyle{headings}{(\textwidth,1pt)%         header
                          {\headmark\hfill}%
