39 * widget for displaying a list of notices
41 * There are a number of actions that display a list of notices, in
42 * reverse chronological order. This widget abstracts out most of the
43 * code for UI for notice lists. It's overridden to hide some
44 * data for e.g. the profile page.

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