714 * The SimplePie class contains feed level data and options
716 * There are two ways that you can create a new SimplePie object. The first
717 * is by passing a feed URL as a parameter to the SimplePie constructor
718 * (as well as optionally setting the cache location and cache expiry). This
719 * will initialise the whole feed with all of the default settings, and you
720 * can begin accessing methods and properties immediately.
722 * The second way is to create the SimplePie object with no parameters
723 * at all. This will enable you to set configuration options. After setting
724 * them, you must initialise the feed using $feed->init(). At that point the
725 * object's methods and properties will be available to you. This format is
726 * what is used throughout this documentation.
729 * @since 1.0 Preview Release
730 * @param string $feed_url This is the URL you want to parse.
731 * @param string $cache_location This is where you want the cache to be stored.
