How to install "sw20­jart.sty"?

Question

I've search internet and found below code:

%sw20jart {Article: JEEP (a general purpose vehicle)}{12pt}{article}{empty}
%Copyright (C) 1994-95 TCI Software Research
\typeout{TCI Document Style `sw20jart' <1 July 1994>.}
\typeout{NOTICE:  This macro file is NOT proprietary and may be 
freely copied and distributed.}
%
\input{jeep.sty}
\input thmsupp.tex %TCI theorem option support
\cfoot{\thepage}%
\tighttoc%
\numberbysection%
\thispagestyle{empty}%
%
% The following is included to suppress page numbers on the first page
% when a title is used.
\def\maketitle{\par
 \begingroup
   \def\thefootnote{\fnsymbol{footnote}}%
   \def\@makefnmark{\hbox
       to\z@{$\m@th^{\@thefnmark}$\hss}}%
   \if@twocolumn
     \twocolumn[\@maketitle]%
     \else \newpage
     \global\@topnum\z@
%     \@maketitle \fi\thispagestyle{plain}\@thanks  % Page number on first page
     \@maketitle \fi\thispagestyle{empty}\@thanks  % No page numbers
 \endgroup
 \setcounter{footnote}{0}%
 \let\maketitle\relax
 \let\@maketitle\relax
 \gdef\@thanks{}\gdef\@author{}\gdef\@title{}\let\thanks\relax}

Is it the package I'm searching for?
If Yes, How can I install it?

Answer 1

The sw20jart.sty belongs to Scientific WorkPlace (SWP) and, as far as I can see, it just does some (bad) redefinition of standard commands. It also loads jeep.sty that is a LaTeX 2.09 style file and which does similar bad redefinitions.

The file thmsupp.sty does nothing at all: it just defines package options that are not used because of the way the file is loaded.

The tcilatex.tex file that's probably also loaded does nothing: it is a compatibility layer for SWP, that only influences the screen output on the front-end.

Thus you should be safe in commenting out both

\usepackage{sw20jart}

and

\input{tcilatex}

Maybe the output will be different from the original, but the important thing is, I guess, that the file can be processed without errors.
