[Zope-dev] Version -> Version Control System??

Hi, Looked at the version feature of Zope. All nice and good. But it would be great, cool etc. to have a version control system like RCS, CVS integrated in Zope. Each time a document is changed a version number is incremented and a backup or differences are stored etc. On a larger scale this would be required. Cannot see that this would be impossible to implement, though I cannot do it myself, since I`m a Zope newbie. ;-> Anyhow, just an idea. Thomas
