+% 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
