% \DescribeMacro{\SetParskip}
% The package provides identical distance between all paragraphs except
% section markups. It redefines control list commands and suppress
% |\topskip|, |\partopskip|, and |\itemsep| in lists. As a result, the distance
% between ordinary paragraphs and paragraphs prepared by lists is the same.
% The command |\SetParskip|\marg{distance} controls this distance.
% The default distance is
% \begin{quote}
% |\SetParskip{4pt plus 1pt minus .2pt}|
% \end{quote}
% In this document, we use |\SetParskip{6pt plus 1pt minus .4pt}|.

% \section{The Implementation}
%
% \begin{macro}{\SetParskip}
% Define the command and set list skips to zero length.
%    \begin{macrocode}
%<*package>
\newcommand*{\SetParskip}[1]{\setlength{\parskip}{#1}\parsep\parskip}
\partopsep\z@
\topsep\z@
\itemsep\z@
%    \end{macrocode}
% \end{macro}
%
% We suppose that list definitions were done in the similar way as
% in standard \LaTeX\ classes. Redefine list control commands:
%    \begin{macrocode}
\def\@listi{\leftmargin\leftmargini}
\let\@listI\@listi
\def\@listii{\leftmargin\leftmarginii
  \labelwidth\leftmarginii \advance\labelwidth-\labelsep}
\def\@listiii{\leftmargin\leftmarginiii
  \labelwidth\leftmarginiii \advance\labelwidth-\labelsep}
%    \end{macrocode}
%
% Redefine the |\normalsize|, |\small|, and |\footnotesize|
% commands to avoid the |\@listi| redefinition in them.
%    \begin{macrocode}
\let\NCC@normalsize\normalsize
\def\normalsize{\let\NCC@temp\@listi\NCC@normalsize\let\@listi\NCC@temp}
\let\NCC@small\small
\def\small{\let\NCC@temp\@listi\NCC@small\let\@listi\NCC@temp}
\let\NCC@footnotesize\footnotesize
\def\footnotesize{\let\NCC@temp\@listi\NCC@footnotesize\let\@listi\NCC@temp}
%    \end{macrocode}
%
% Finally we set defaults:
%    \begin{macrocode}
\normalsize
\SetParskip{4pt plus 1pt minus .2pt}
%</package>
%    \end{macrocode}
