 \section{Introduction}
 
-The \packagename\ package allows you to embed graphs written the DOT description language directly in your document. The dot2tex\footnote{Available from: \url{http://www.fauskes.net/code/dot2tex/}}\footnote{and \url{http://www.ctan.org/tex-archive/help/Catalogue/entries/dot2tex.html}} tool is used to transform the output from Graphviz to \LaTeX\ code using either the TikZ and PGF package, or the PSTricks package. The generated code can then be included directly in you document. This package can automate the process if shell escape is enabled.
