% parskip.sty; last edited by Robin Fairbairns (rf10@cam.ac.uk),
% derived from:
%
% This is PARSKIP.STY by H.Partl, TU Wien, as of 19 Jan 1989.
%
% Package to be used with any document class at any size.
% It produces the following Paragraph Layout:
% Zero Parindent and non-zero Parskip. The stretchable glue in \parskip
% helps LaTeX in finding the best place for page breaks.
%
% This package is no more than quick fix; the `proper' way to achieve
% effects as far-reaching as this is to create a new class. An
% example class is to be found in the ntgclass set: artikel3.cls
\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{parskip}[2001/04/09 non-zero parskip adjustments]
\parskip=0.5\baselineskip \advance\parskip by 0pt plus 2pt
\parindent=\z@
%
% from a suggestion by Donald Arseneau on comp.text.tex:
\DeclareOption{parfill}{\setlength{\parfillskip}{30\p@ \@plus 1fil}}
\ProcessOptions
% To accompany this, the vertical spacing in the list environments is changed
% to use the same as \parskip in all relevant places (for normalsize only):
% \parsep = \parskip
% \itemsep = \z@ % add nothing to \parskip between items
% \topsep = \z@ % add nothing to \parskip before first item
\def\@listI{\leftmargin\leftmargini
\topsep\z@ \parsep\parskip \itemsep\z@}
\let\@listi\@listI
\@listi
\def\@listii{\leftmargin\leftmarginii
\labelwidth\leftmarginii\advance\labelwidth-\labelsep
\topsep\z@ \parsep\parskip \itemsep\z@}
\def\@listiii{\leftmargin\leftmarginiii
\labelwidth\leftmarginiii\advance\labelwidth-\labelsep
\topsep\z@ \parsep\parskip \itemsep\z@}
% and, now...
% \partopsep = \z@ % don't even add anything before first item (beyond
% % \parskip) even if the list is preceded by a blank line
\partopsep=\z@
% Note that listiv, listv and listvi don't change vertical parameters.
% deal with a problem raised on comp.text.tex in april 2001
%
% don't expand the table of contents any further
%
% first: check that the definition of \@starttoc is unchanged from
% that in latex.ltx
