38 * widget for displaying a single notice
40 * This widget has the core smarts for showing a single notice: what to display,
41 * where, and under which circumstances. Its key method is show(); this is a recipe
42 * that calls all the other show*() methods to build up a single notice. The
43 * ProfileNoticeListItem subclass, for example, overrides showAuthor() to skip
44 * author info (since that's implicit by the data in the page).
