I know nothing about Python and Zope :-(

I've successfully installed Zope and Python in a Debian GNU/Linux box.
I've unpacked Openflow "tgz" in the right place and I can see it from Zope (/Control_Panel/Products).
And then?!

How can I deploy a flow?! Shall I configure a file, is there any web-gui?
I've not found a "User manual"...
Or is Openflow a _framework_only_ package?!

Thanks
Tiian
