Book News Annotation:
For software developers well acquainted with the object-oriented scripting language Python, Richter (physics, Tufts U.) explains the open-source platform for building Web-based content management systems. He refers to Zope 3, which uses many of the latest development patterns and technologies, but also reuses some parts developed for previous versions of Zope.
