	 *
	 * - Can be passed 4 subactions which decide what is output:
	 *     * 'recent' for recent posts,
	 *     * 'news' for news topics,
	 *     * 'members' for recently registered members,
	 *     * 'profile' for a member's profile.
	 * - To display a member's profile, a user id has to be given. (;u=1) e.g. ?action=.xml;sa=profile;u=1;type=atom
	 * - Outputs a feed based on the 'type'
	 *       * parameter is 'rss', 'rss2', 'rdf', 'atom'.
	 * - Several sub action options are respected
	 *     * limit=x - display the "x" most recent posts
	 *     * board=y - display only the recent posts from board "y"
	 *     * boards=x,y,z - display only the recent posts from the specified boards
	 *     * c=x or c=x,y,z - display only the recent posts from boards in the specified category/categories
	 *     * action=.xml;sa=recent;board=2;limit=10
	 * - Accessed via ?action=.xml
	 * - Does not use any templates, sub templates, or template layers.
	 * - Use ;debug to view output for debugging feeds
	 *
	 * @uses Stats language file.
