[Zope] any good a to z tutorials?

is there a tutorial or document anywhere that might be able to help me get started? I have been playing for 4 hours with the 'variable' strings, and for some strange reason I think there is more to zope than that. I need a one stop crash course, because honestly, I have worked with Sun Microsystems NetDynamics, and PHP3 before, and cought on really fast, with zope I am just list.. I thought I was an object oriented person too... :) any help would be great.... -chris
