% \begin{abstract}
% This is \texttt{scrpage.sty}. This package is part of the
% \textsf{KOMA}-script-bundle. It defines a new user-interface for
% pagestyle-definition. It's something like \texttt{fancyheadings}
% but not the same. You may use \texttt{scrpage} or \texttt{fancyheadings}.
% You may use \texttt{scrpage} with standard classes, too.
% \end{abstract}
%
% \tableofcontents
%
% \section{Introduction}
%
% There is a simple user-interface and a expert-interface. Using the
% user-interface you can define a lot of different pagestyles. But there are
% combinations, you cannot define. Using the expert-interface you can do
% allmost all you may ever want. To do more, you should learn more about
% defining macros yourself.
%
%
% \subsection{Interface for all users}
%
% \DescribeMacro
% \headfont\\
% This font is used to write pageheads and -foots. You may change it using
% |\renewcommand|, e.g. |\renewcommand\headfont{\normalfont\slshape}|.
%
% \DescribeMacro
% \headmark\\
% Using \texttt{twoside}-option this is |\leftmark| at left/even pages and
% |\rightmark| at right/odd pages. Using \texttt{oneside}-option there are
% only right pages, so it is |\rightmark|.
%
% \DescribeMacro
% \pnumfont\\
% This font is used to write pagenumbers at |\pagemark|. You may change it
% using |\renewcommand| (see |\headfont|).
%
% \DescribeMacro
% \pagemark\\
% This is the number of the actual page written with |\pnumfont|.
%
% \DescribeMacro
% \deftripstyle\arg{name}\oarg{olw}\oarg{ilw}%
%              \arg{headleft}\arg{headmiddle}\arg{headright}%
%              \arg{footleft}\arg{footmiddle}\arg{footright}\\
% Defines a new pagestyle. You can activate this pagestyle using
% |\pagestyle| or |\thispagestyle|. Without optional argument this defines a
% page like this:
% \begin{center}\unitlength1mm\begin{picture}(120,82)
% \put(0,0){\dashbox{2}(58,82){~}}
% \put(1,78){\makebox(0,0)[l]{\emph{headright}}}
% \put(29,78){\makebox(0,0){\emph{headmiddle}}}
% \put(57,78){\makebox(0,0)[r]{\emph{headleft}}}
% \put(29,41){\makebox(0,0){left page}}
% \put(1,3){\makebox(0,0)[l]{\emph{footright}}}
% \put(29,3){\makebox(0,0){\emph{footmiddle}}}
% \put(57,3){\makebox(0,0)[r]{\emph{footleft}}}
% \put(60,0){\dashbox{2}(58,82){~}}
% \put(61,78){\makebox(0,0)[l]{\emph{headleft}}}
% \put(89,78){\makebox(0,0){\emph{headmiddle}}}
% \put(117,78){\makebox(0,0)[r]{\emph{headright}}}
% \put(89,41){\makebox(0,0){right page}}
% \put(61,3){\makebox(0,0)[l]{\emph{footleft}}}
% \put(89,3){\makebox(0,0){\emph{footmiddle}}}
% \put(117,3){\makebox(0,0)[r]{\emph{footright}}}
% \end{picture}\end{center}
% Using one optional argument \oarg{ilw} (means \emph{i}nner \emph{l}ine
% \emph{w}idth) you get a separationline between head and text and between
% text and foot like this (\emph{ilw}=0.5pt):
% \begin{center}\unitlength1mm\begin{picture}(120,82)
% \put(0,0){\dashbox{2}(58,82){~}}
% \put(1,78){\makebox(0,0)[l]{\emph{headright}}}
% \put(29,78){\makebox(0,0){\emph{headmiddle}}}
% \put(57,78){\makebox(0,0)[r]{\emph{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]{\emph{footright}}}
% \put(29,3){\makebox(0,0){\emph{footmiddle}}}
% \put(57,3){\makebox(0,0)[r]{\emph{footleft}}}
% \put(60,0){\dashbox{2}(58,82){~}}
% \put(61,78){\makebox(0,0)[l]{\emph{headleft}}}
% \put(89,78){\makebox(0,0){\emph{headmiddle}}}
% \put(117,78){\makebox(0,0)[r]{\emph{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]{\emph{footleft}}}
% \put(89,3){\makebox(0,0){\emph{footmiddle}}}
% \put(117,3){\makebox(0,0)[r]{\emph{footright}}}
% \end{picture}\end{center}
% Using both optional arguments \oarg{olw} (means \emph{o}uter \emph{l}ine
% \emph{w}idth) and \oarg{ilw} you get a separationline between head and
% text and between text and foot and a line above head and below foot like
% this (\emph{olw}=2pt, \emph{ilw}=0.5pt):
% \begin{center}\unitlength1mm\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]{\emph{headright}}}
% \put(29,78){\makebox(0,0){\emph{headmiddle}}}
% \put(57,78){\makebox(0,0)[r]{\emph{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]{\emph{footright}}}
% \put(29,3){\makebox(0,0){\emph{footmiddle}}}
% \put(57,3){\makebox(0,0)[r]{\emph{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]{\emph{headleft}}}
% \put(89,78){\makebox(0,0){\emph{headmiddle}}}
% \put(117,78){\makebox(0,0)[r]{\emph{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]{\emph{footleft}}}
% \put(89,3){\makebox(0,0){\emph{footmiddle}}}

%
% You can define new pagestyles and you can redefine existing pagestyles. If
% you redefine an active pagestyle, this doesn't change the actual shown
% pagestyle. To activate you have to use always a |\pagestyle|- or
% |\thispagestyle|-command.
%
% You can change the standard pagestyle \texttt{headings} to. If you want to
% change pagestyle \texttt{myheadings}, you should use the star-version of
% the command:\\
% \DescribeMacro
% \deftripstyle\star\arg{name}\oarg{olw}\oarg{ilw}%
%               \arg{headleft}\arg{headmiddle}\arg{headright}%
%               \arg{footleft}\arg{footmiddle}\arg{footright}\\
% this defines a my-version pagestyle. This means, section- and
% chapter-commands or perhaps |\tableofcontents| don't change the
% marks. Only |\markboth| and |\markright| change them. But if you don't
% use |\headmark|, |\leftmark| or |\rightmark|, star- and starless version
% of |\deftripstyle| are almost the same.
%
%
% \subsection{Interface for experts}
%
% \DescribeMacro
% \defpagestyle\arg{name}\arg{head-definition}\arg{foot-definition}\\
% defines a new pagestyle \emph{name}. \emph{head-definition} defines the
% head at the new pagestyle. It contains five part:\\
% (\emph{toplinelength},\emph{toplinewidth})%
% \arg{evenpagehead}\arg{oddpagehead}\arg{onesidepagehead}%
% (\emph{headseplinelength},\emph{headseplinewidth})\\
% These five parts have to be \textbf{one} argument! So you should put them
% together in group-braces (``|{|'' and ``|}|'').
%
% \emph{foot-definition} analogous defines the foot at the new pagestyle.
%
% \DescribeMacro
% \newpagestyle\arg{name}\arg{head-definition}\arg{foot-definition}\\
% defines a real new pagestyle. If there's already a pagestyle named
% \emph{name}, you'll get an error. Otherwise it's the same like
% |\defpagestyle|.
%
% \DescribeMacro
% \renewpagestyle\arg{name}\arg{head-definition}\arg{foot-definition}\\
% redefines a old pagestyle. If there isn't a pagestyle named
% \emph{name}, you'll get an error. Otherwise it's the same like
% |\defpagestyle|.
%
% \DescribeMacro
% \providepagestyle\arg{name}\arg{head-definition}\arg{foot-definition}\\
% defines a new pagestyle, if it is realy new. If there is already a
% pagestyle named \emph{name}, it does nothing (but writing an info to
% the log file). Otherwise it's the same like |\defpagestyle|.
%
% You may use the user-interface-macros |\pagemark| and |\headmark|, too.
%
%
% \subsection{Configuration file}
% There's a configuration file \texttt{scrpage.cfg}, included at the end
% of \texttt{scrpage.sty}, if it exists. There you can define your own
% default pagestyles using all the commands above.
%
%
% \subsection{Example}
% The pagestyles of this documentation was defined using:
% \begin{verbatim}
% \renewpagestyle{headings}{(\textwidth,1pt)%
%                 {\headmark\hfill}{\hfill\headmark}{\hfill\headmark\hfill}%
%                 (\textwidth,.4pt)}%
%                {(\textwidth,.4pt)%

% \renewpagestyle{plain}{(\textwidth,1pt)%
%                        {\hfill}{\hfill}{\hfill}%
%                        (\textwidth,.4pt)}%
%                       {(\textwidth,.4pt)%
%                        {\pagemark\hfill}%
%                        {\hfill\pagemark}%
%                        {\hfill\pagemark\hfill}%
%                        (\textwidth,1pt)}
% \pagestyle{headings} % activate new version
% \end{verbatim}
%
%
% \StopEventually
%
% \section{Implementation}
%    \begin{macrocode}
%<*scrpage>
%    \end{macrocode}
% \changes{v1.1}{1995/06/27}{\cs{hbox to} changed into \cs{hb@xt@}.}
%
% \subsection{Options}
% \texttt{scrpage} knows some options. They are similar to the
% \textsf{KOMA}-script-classes. To work with and without
% the \textsf{KOMA}-script-classes their definitions are not quite simple.
%
%    \begin{macrocode}
\DeclareOption{headinclude}{\PassOptionsToPackage{headinclude}{typearea}}
\DeclareOption{headexclude}{\PassOptionsToPackage{headexclude}{typearea}}
\DeclareOption{footinclude}{\PassOptionsToPackage{footinclude}{typearea}}
\DeclareOption{footexclude}{\PassOptionsToPackage{footexclude}{typearea}}
%    \end{macrocode}
% We do so, because we want so set |headinclude|, |footinclude| by default!
%    \begin{macrocode}
\ExecuteOptions{headinclude,footinclude}
%    \end{macrocode}
% But you may set other Options:
%    \begin{macrocode}
\ProcessOptions
%    \end{macrocode}
%
%
% \subsection{Some Initialisation}
%
% For easier handling of the differences between article-, report- and
% book-classes we define some more switches.
%
%  \begin{macro}{\if@chapter}
% First distinguish between article and others.
%    \begin{macrocode}
\newif\if@chapter
\ifx\chapter\undefined \@chapterfalse\else\@chaptertrue\fi
%    \end{macrocode}
%  \end{macro}
%
%  \begin{macro}{\if@mainmatter}
% \changes{v1.2}{1995/07/08}{Definition ge"andert}
% Next distinguish between matter- and nomatter-classes.
%    \begin{macrocode}
\def\@tempa{\newif\if@mainmatter\@mainmattertrue}
\ifx\mainmatter\undefined\else\let\@tempa\relax\fi
\@tempa
%    \end{macrocode}
%  \end{macro}
%
%
% \subsection{Predefinitions}
% There are some commands, you can use at pagestyle-definition.
%
%  \begin{macro}{\headmark}
% This macro is |\rightmark| or |\leftmark|. But outside pagestyle-definition
% it's nothing.
%    \begin{macrocode}
\let\headmark\relax
%    \end{macrocode}
%  \end{macro}
%
%  \begin{macro}{\pagemark}
% This macro is the number of the page at the pagenumberfont:
%    \begin{macrocode}
\DeclareRobustCommand\pagemark{{\pnumfont\thepage}}
%    \end{macrocode}
%  \end{macro}
%
%
% \subsection{Expert-Pagestyle-Definition-Interface}
% The pagestyle-definition-interface for experts is not as easy as the
% simple interface we'll define later. But it's more flexible. We'll later use
% is to define the pagestyle-definition-interface for users.
%
%  \begin{macro}{\defpagestyle}
% First we define the simple definition-interface. There's no test, if
% the pagestyle's defined twice.
%
% First there has to be the definition of head and foot.
%    \begin{macrocode}
\def\defpagestyle{%
%    \end{macrocode}
% We have to decide, wether it is a my-version or not:
%    \begin{macrocode}
  \@ifstar
  {\@defpagestyle[-]}%
  {\@defpagestyle[+]}}
%    \end{macrocode}
% Now the we can define the head and the foot. First at twoside-mode:
% \changes{v1.0b}{1995/05/25}{Dot deleted after number at
%                             chapter- and sectionmark}

% This was real simple, but we already have to do the real definition of the
% heads and foots. First the twosided head:
%  \begin{macro}{\def@twosidehead}
%    \begin{macrocode}

%    \end{macrocode}

%    \begin{macrocode}
\def\def@twosidefoot(#1,#2)#3#4#5(#6,#7){
  \def\@evenfoot{\let\headmark\leftmark%

% \subsection{User-Pagestyle-Definition-Interface}
% The pagestyle-definition-interface for users is much easier than the
% expert-version. Using the expert-macros, the definition is easy, too.
%
% First we define the selection of star- or starless-version:
%  \begin{macro}{\deftripstyle}
%    \begin{macrocode}
\def\deftripstyle{%
  \@ifstar
  {\@deftripstyle[-]}%
  {\@deftripstyle[+]}}
%    \end{macrocode}
%  \end{macro}
% Next we check, if there is an optional argument:
%  \begin{macro}{\@deftripstyle}
%    \begin{macrocode}
\def\@deftripstyle[#1]#2{%
  \@ifnextchar[
  {\@@deftripstyle[#1]{#2}}%
  {\@@deftripstyle[#1]{#2}[\z@]}}
%    \end{macrocode}
%  \end{macro}
% or perhaps two optional arguments:
%  \begin{macro}{\@@deftripstyle}
%    \begin{macrocode}
\def\@@deftripstyle[#1]#2[#3]{
%    \end{macrocode}
% Ok, now we have the problem, that there can be only 9 arguments. So we
% have to distinguish the star-versions by a macro:
%    \begin{macrocode}
  \def\@tempa{#1}
  \@ifnextchar[
  {\@@@deftripstyle#2[#3]}%
  {\@@@deftripstyle#2[\z@][#3]}}
%    \end{macrocode}
%  \end{macro}
% Now the main-definition:
%  \begin{macro}{\@@@deftripstyle}
%    \begin{macrocode}
\def\@@@deftripstyle#1[#2][#3]#4#5#6#7#8#9{%
  \def\@tempb{+}
  \ifx\@tempa\@tempb%
    \defpagestyle{#1}%
      {(\textwidth,#2)%

       {\rlap{#4}\hfill{#5}\hfill\llap{#6}}%
       {\rlap{#4}\hfill{#5}\hfill\llap{#6}}%
       (\textwidth,#3)}
      {(\textwidth,#3)%
       {\rlap{#9}\hfill{#8}\hfill\llap{#7}}%
       {\rlap{#7}\hfill{#8}\hfill\llap{#9}}%
       {\rlap{#7}\hfill{#8}\hfill\llap{#9}}%

  \else
    \defpagestyle*{#1}%

       {\rlap{#9}\hfill{#8}\hfill\llap{#7}}%

% \subsection{Fonts}
%  \begin{macro}{\pnumfont}

%    \begin{macrocode}
\providecommand\pnumfont{\normalfont}

%  \end{macro}
%
%  \begin{macro}{\headfont}
