% Change history
%
Version Date Changes

Nelson Beebe; make text ragged right, lightface, and
entries closer together than latex.tex default
1.18b 8 Nov 93 removed extraneous " from header
1.18a 29 May 93 changed \family to \fontfamily in defs of \tensl, \tenuit
within \sectitlefont, define \La to get proper "A"
1.18 22 Mar 93 added \hyphenpenalty=10000 to (sub*)section headings
added missing brace at end of \def\tensl for nfss
added new environments \dedication and \longabstract
1.17 19 Feb 93 incorporated some font definitions by Rainer Schoepf
to add flexibility when used under NFSS
installed new TUG address and phone number in header
reformatted change history, similar to tugboat.sty
1.16e 24 Dec 92 decreased skip above \paragraph, \subparagraph;
removed shrink
defined \ps@titlepage to get running heads on first page
of docstyle articles
1.16d 19 Oct 92 added \SMC parallel to plain-based style
1.16c 10 Sep 92 added \raggedright in \subsubsection
1.16b 19 Jul 92 test for previous input of article.sty, and omit if
done already, to permit use as style option
1.16a 29 Jun 92 embedded redefinitions of \xpt, \ixpt within code to
distinguish between plain/old LaTeX and nfss
1.16 6 Jun 92 incorporated test for nfss, and if loaded, define \tensl
1.15 16 Mar 92 incorporated \sevbf into \*scriptfont of \bffam for \ixpt
to improve appearance of LaTeX and other logos
1.14 8 Mar 92 added \input article.sty to make this an independent style
added standard headers, prepared for archive installation
1.13 20 Nov 91 modified \@outputdblcol to reset \brokenpenalty to
different values in first and second column
added initialization macro (\tugstyinit) for multiple
articles
1.12 7 Aug 91 modified \thebibliography to make it not quite so sloppy
and avoid cases where all stretch is put into one line
1.11 10 Jun 91 added \ifWideSecTitle and modified \@maketitle to
(partially) support it
1.10 13 Feb 91 added \egtsl and incorporated it into \*scriptfont of
\slfam for \xpt to improve appearance of LaTeX and
other logos
1.09 12 Dec 90 modified \@oddhead and \@evenhead to reset `shape' for
new font selection scheme
1.08 25 Oct 90 modified \enddocument to use \@@input instead of \input;

set \marginparwidth in \SelfDocumenting
removed stretch in space between footnotemark and
footnotetext

\@tubfilename)
1.06 13 Oct 90 added \listparindent=1em to definitions of \@list...
in order to distinguish paragraphs
1.05 1 Sep 90 made space a <space> in definition of \@netaddress;

after leading rule
1.03 25 Feb 90 added definition of \thistubstyle
1.02 12 Feb 90 modified definition of \@makefntext; now uses
