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