Re: PGF v2.0 manual page 46 (petri net) seems to not work

Hi all,

OK, I found I have to use a couple of libraries:

\usetikzlibrary{positioning}
\usetikzlibrary{arrows}
\usetikzlibrary{petri}
\usetikzlibrary{decorations.pathmorphing}
\usetikzlibrary{fit}

and some definitions:

\pgfdeclarelayer{background}
\pgfdeclarelayer{foreground}
\pgfsetlayers{background,main,foreground}

I use PGF/Tikz with xelatex and it seems to work well.
I'm impresed with the possibilities, but the learning
curve is indeed steep.
