% \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.
%
% \begin{macro}{\deftripstyle}
%    \begin{macrocode}
%    \end{macrocode}
% At version 1 we define the selection of star- or starless-version first:
%    \begin{macrocode}
\def\deftripstyle{%
  \@ifstar
  {\@deftripstyle[-]}%
  {\@deftripstyle[+]}}
%    \end{macrocode}
% \end{macro}
% Next we check, if there is an optional argument:
% \begin{macro}{\@deftripstyle}
%   \changes{v3.20}{2016/04/12}{\cs{@ifnextchar} replaced by
%     \cs{kernel@ifnextchar}}^^A
%    \begin{macrocode}
\def\@deftripstyle[#1]#2{%
  \kernel@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}
%   \changes{v3.20}{2016/04/12}{\cs{@ifnextchar} replaced by
%     \cs{kernel@ifnextchar}}^^A
% 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}%
  \kernel@ifnextchar[%]
  {\@@@deftripstyle#2[#3]}%
  {\@@@deftripstyle#2[\z@][#3]}}

% Maybe you want to clear the currently defined head and foot. First
% let's clear only scrheadings pagestyle but not scrplain pagestyle.
% We do this simply using the already known command:
%    \begin{macrocode}
\newcommand*{\clearscrheadings}{%
  \ihead{}\chead{}\ohead{}\ifoot{}\cfoot{}\ofoot{}}
%    \end{macrocode}
% We can do almost the same to clear scrheadings pagestyle and
% scrplain pagestyle together:
%    \begin{macrocode}
\newcommand*{\clearscrheadfoot}{%
  \ihead[]{}\chead[]{}\ohead[]{}\ifoot[]{}\cfoot[]{}\ofoot[]{}}
%    \end{macrocode}
% But, for only clearing the scrplain pagestyle, we have to do the
% redefinition directly:
%    \begin{macrocode}
\newcommand*{\clearscrplain}{%
  \renewcommand*{\scrplain@even@left@head}{}%
  \renewcommand*{\scrplain@even@middle@head}{}%
