ZenWeb is a system for building entire websites, not just pages. It allows you to focus on the content and the structure of the website, while leaving page construction, markup, layout, navigation as secondary concerns.
ZenWeb provides tools for complete website design and creation, simple paragraph to HTML generation with embellishments, and a rich set of tools for page and website creation, modification, and customization.
ZenWeb extends traditional web tools by being site oriented instead of page oriented. This allows you to focus on the quality and consistancy of the whole system instead of only being able to focus on a page at a time.
It is based around a sitemap. This sitemap defines the structure of your site and allows you to focus on the whole website in a single view. Pages know their relationships to others (children, parents, siblings) as a consequence and all navigation tools are automatically created by ZenWeb.
