Plone is an open source content management system (CMS) built using Python and the Zope framework. It has been used by government agencies, universities, and non-profits for its security, customizability, and intuitive interface. Plone supports advanced features like workflows, versioning, search, and internationalization. While more resource-intensive than other options, it can scale well and is well-suited for complex websites with multiple editors and fine-grained permissions.

16. Deployment
Not your typical php deployment...
Requires long running python process
Scalable--easy to use multiple clients that connect back to
the database server

automatic purge requests

configuration so development can easily mirror deployment
