+ (description
+ "The purpose of @code{dot2tex} is to give graphs generated by Graphviz a
+more LaTeX friendly look and feel. This is accomplished by converting
+@code{xdot} output from Graphviz to a series of PSTricks or PGF/TikZ commands.
+This approach allows:
+
+@itemize @bullet
+@item Typesetting labels with LaTeX, allowing mathematical notation
+@item Using native PSTricks and PGF/TikZ commands for drawing arrows
+@item Using backend specific styles to customize the output
+@end itemize")
