% \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}}}
% \put(117,3){\makebox(0,0)[r]{\emph{footright}}}
% \put(61,1){\rule{56\unitlength}{2pt}}
% \end{picture}\end{center}
%
% 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 parts:
% \begin{flushleft}
% (\emph{toplinelength},\emph{toplinewidth})\\%
% \arg{evenpagehead}\arg{oddpagehead}\arg{onesidepagehead}\\%
% (\emph{headseplinelength},\emph{headseplinewidth})\\
% \end{flushleft}
% 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}%

%
% \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.

%    \end{macrocode}
% We do so, because we want so set |headinclude|, |footinclude| by
% default at old version (see below)!
%
% At version 2 we have additonal options designed for the additional

% There are documents where the head and foot should span not only the

% initialization. This option corresponds with the option of package
% \texttt{typearea} and the classes.

% Until version 1.3, head and foot of a page had same width like the
% text block. Since version 1.3 this was changed. Now the head and
% foot have their own width and an optional shift relative to the text
% part of the page. This shift can be positive or negative. We set
% the width and shift with one macro and save them at macros. The set
% macros have an optional argument: the shift.
%
% For definition of symbolic length values there is the macro
% \cs{settowidthof}. And to define a macro with this value, there
% is \cs{deftowidthof}.
