That script was designed to make the network look like it was before you
installed xen. Anyone with anything beyond a basic single-port
single-vlan setup comments that line out and creates their own bridges.

This is an open source project. Please feel free to submit your own
scripts. I'd definitely like to see something that didn't create
firewall rules as I don't even want iptables loaded on my xen systems.
