The Super Page plugin for Movable Type was created in support of Movable Type's documentation effort. The basic need was this: convert a single, massive page into a set of paginated, easy to navigate pages broken up by chapter/section.
This plugin solves that problem by allowing authors to flag a regular Movable Type page as a "Super Page." When that page is saved, the plugin will automatically partition it into multiple pages and generate a table of contents for the Super Page. The plugin also makes available a set of template tags that allow you to construct next page and previous page links for all of the child pages derived from the parent Super Page.
Each "child page" is delineated by a HTML header.
