709 - * The SimplePie class contains feed level data and options
711 - * There are two ways that you can create a new SimplePie object. The first
712 - * is by passing a feed URL as a parameter to the SimplePie constructor
713 - * (as well as optionally setting the cache location and cache expiry). This
714 - * will initialise the whole feed with all of the default settings, and you
715 - * can begin accessing methods and properties immediately.
717 - * The second way is to create the SimplePie object with no parameters
718 - * at all. This will enable you to set configuration options. After setting
719 - * them, you must initialise the feed using $feed->init(). At that point the
720 - * object's methods and properties will be available to you. This format is
721 - * what is used throughout this documentation.
