741 - * is by passing a feed URL as a parameter to the SimplePie constructor
742 - * (as well as optionally setting the cache location and cache expiry). This
743 - * will initialise the whole feed with all of the default settings, and you
744 - * can begin accessing methods and properties immediately.
746 - * The second way is to create the SimplePie object with no parameters
747 - * at all. This will enable you to set configuration options. After setting
748 - * them, you must initialise the feed using $feed->init(). At that point the
749 - * object's methods and properties will be available to you. This format is
750 - * what is used throughout this documentation.
