Re: [Openflow-dev] Getting started with OpenFlow

[Francesco C. <cir...@ti...>]

Hi!

as co-mantainer of CMFOpenflow (aka Reflow) I would be glad to help you i=
f you=20
want to use it.

Latest version is 1.0.9 available con collective cvs or=20
www.reflab.it/community/Openprojects/CMFOpenflow

CMFOpenflow is integrated into CMF (and Plone in particular) but can be a=
lso=20
used without it (so you don't need CMF nor Plone)

Sorry for the scarce documentation;=20
right now some of us are writing an how-to-start-with-reflow and we just=20
released two demo applications (as CMF Products) that could help you writ=
ing=20
your "first CMFOpenflow application".=20
A "technical" developer manual has also available (both in Italian and in=
=20
English).

regards,
francesco.
