Zope, the leading Open Source Web application server, helps teams of developers create and manage dynamic, Web-based business applications like Intranets and portals. Zope makes it easy to add features such as site search, news, personalization, and e-commerce. The Book of Zope is a comprehensive introduction to Zope, covering installation; DTML programming; concepts such as users, roles, and permissions; ZClasses; ZCatalog; databases; programming Zope with Python; debugging; and the use of external data sources. Zope runs on Windows and almost all Unix-based platforms, and includes its own Web server, transactional object-oriented database, search engine, Web page templating system, Web development and management tool, and comprehensive extension support.
This is another introduction to Zope. Nothing to write home about, a bit dated, badly edited, but mostly correct.
In short, why not?
