-\section{Introduction}
-
-Crossrefware is a collection of Perl scripts used to help to submit
-the documents to \url{http://www.crossref.org}.
-
-To use scrips you need a number of standard Perl libraries:
-\begin{enumerate}
-\item \path{Text::BibTeX} by Greg Ward,
-\item \path{TeX::Encode} by Timothy D Brody
-\end{enumerate}
-They are included in most standard Perl distributions, or can be
-installed from \url{http://www.cpan.org}.
+These scripts can be used to submit files to Crossref, check and add
+doi numbers and ZbMath numbers to papers.
