[Zope] Workflow Product

I am searching a workflow product. I discovered two: DCWorkflow in CMF and OpenFlow. I tried the OpenFlow some time ago and it doesn't seem to be stable. Can someone copmare DCWorkflow and OpenFlow? How stable is DCWorkflow? Can it be used without CMF, too? I am just interested in a workflow, not in skinable GUIs or dublin core. BTW, I thing the documentation about CMF should tell more facts. -- Open Source Software Solutions Thomas Guettler <guettli@thomas-guettler.de> http://www.thomas-guettler.de
