Hello, i have been reading about zope and plone for a few days now, and i have a question that i could not find an answer to. i understand zope is a server, that is, it is a process in OS. from what i could gather from the documentation, plone is a cms built on top of zope. why then when i install plone for windows from an msi, it appears that plone is also a server that runs alongside zope server just on a different http port? in addition, why the plone documentation keeps referring to plone as a server, and is using terms such as "start plone" and "stop plone"? so, is it a CMS that runs on top of zope or is it aan its own server? i am totally confused... i hope this is the right list to post this kind of plone questions. if not, i apologise, and i would appreciate if you could redirect me... thanks for any clarifications in advance.
