# Math Help - I got a problem with a elsdoc.tex from elsarticle.sty

1. ## I got a problem with a elsdoc.tex from elsarticle.sty

There is an error: "Something wrong is perhaps a missing \item" (just before \file{article.cls}).I don't know where is a problem as this is an template file from CTAN.Thank you for your attention\begin{enumerate}[\textbullet]
\item\file{elsarticle.cls}
is built upon \file{article.cls}
while \file{elsart.cls} is not. \file{elsart.cls} redefines
many of the commands in the \LaTeX{} classes/kernel, which can
possibly cause surprising clashes with other contributed
\LaTeX{} packages;
\item provides preprint document formatting by default, and
optionally formats the document as per the final
style of models $1+$, $3+$ and $5+$ of Elsevier journals;
\item some easier ways for formatting \verb+list+ and
\verb+theorem+ environments are provided while people can still
use \file{amsthm.sty} package;
\item\file{natbib.sty} is the main citation processing package
which can comprehensively handle all kinds of citations and
works perfectly with \file{hyperref.sty} in combination with
\file{hypernat.sty};
\item long title pages are processed correctly in preprint and
final formats.
\end{enumerate}

Do you really need to compile elsdoc.tex? The elsarticle.zip archive on the Elsevier page and CTAN contain elsdoc.pdf.
