+ * 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.
