The CMS plug-in is the "Website Manager", an advanced Content Management application.  It is the primary tool used to perform more complicated website maintenance tasks, such as:

• installing and updating templates
• configuring multi-lingual websites
• managing and restoring revisions
• creating new sites and subsections
• creating new libraries
• managing secondary content zones on pages
• setting up content sharing and content inheritance
• reconfiguring sections, pages, and content objects
• working with HTML in plain-text mode

CMS data is presented to you in 5 views:

1. your sites or sections
2. your pages in a section
3. content objects in a given page
4. revisions of a content object
5. preview of a particular revision

By clicking on particular objects to open them, you descend down in these views.  You can move back up to higher views by using the "bread-crumb" links showing your current position in the CMS data.  At each view, the menubar changes to provide you with a set of operations you can perform on the object currently being viewed.

The CMS plug-in can handle editable page previews.  (This is where a page preview includes embedded links to edit the content.)  To use CMS, add the following configuration setting to your configuration file:

cms.editmode = easy

(Note that an alternative setting of "MySite" is actually easier than "easy" mode, so this is a bit of a misnomer.)
