One more stupid question ... I've made a few python based external products and am comfortable setting default permissions with those but this is my first foray into a ZMI based product. I've largely followed the ZooExhibit product in the Zope Book (what I'm trying to do is not at all complex but I wanted something distributable ... the ZooExhibit really does fit the general pattern of what I'm trying to do). I have a folder named 'OETemplate' which mirrors the 'exhibitTemplate', and when I install an instance of this product that template works all hunkey-dorey. What I'd like to do is set some default permissions on some of the objects inside that template. Specifically there is a subfolder which I would like to set default permissions for adding & changing files. I've found the "Define Permissions" tab but for the life of me can't really grok the concept. I'm getting the sense that perhaps "you can't get there from here" in what I'm trying to do and that "Define Permissions" is not really the right task I want to use to set default perms for a folder, but there is also not a "Security" tab (which is what I originally figured I'd need to use, I thought that Define Permissions would be to create new permissions).
