/**
 * Display archive links based on type and format.
 *
 * The 'type' argument offers a few choices and by default will display monthly
 * archive links. The other options for values are 'daily', 'weekly', 'monthly',
 * 'yearly', 'postbypost' or 'alpha'. Both 'postbypost' and 'alpha' display the
 * same archive link list, the difference between the two is that 'alpha'
 * will order by post title and 'postbypost' will order by post date.
 *
 * The date archives will logically display dates with links to the archive post
 * page. The 'postbypost' and 'alpha' values for 'type' argument will display
 * the post titles.
 *
 * The 'limit' argument will only display a limited amount of links, specified
 * by the 'limit' integer value. By default, there is no limit. The
 * 'show_post_count' argument will show how many posts are within the archive.
 * By default, the 'show_post_count' argument is set to false.
 *
 * For the 'format', 'before', and 'after' arguments, see {@link
 * get_archives_link()}. The values of these arguments have to do with that
 * function.
 *
 * @since 1.2.0
 *
 * @param string|array $args Optional. Override defaults.
