/**
 * The summary XHTML form selects either up to the first two paragraphs
 * it find in a page or the first section (whichever comes first)
 * It strips out the table of contents if one exists
 * Section divs are not used - everything should be nested in a single
 * div with CSS class "page"
 * Headings have their a name link removed and section editing links
 * removed
 * It also attempts to capture the first heading in a page for
 * use as the title of the page.
 *

 * @author Harry Fuecks <hfuecks@gmail.com>
 * @todo   Is this currently used anywhere? Should it?
