/**
 * Give Me Stuff I Starred - gmsis
 *  by Bill Israel [http://cubicle17.com/]
 *
 * This plugin pulls the last X Instapaper articles you've starred.
 *
 * To use GMSIS, you'll need the URL for your Starred RSS feed, which
 * you can get from http://www.instapaper.com/starred if you're logged in.
 * NOTE: RSS feed URL _must_ start with "http://", not "feed://"
 *
 * Options:
 *  - count: (int) - the number of items to pull (5 by default, max is 25)
 *  - desc: (boolean) - whether to show item descriptions (false by default)
 *
 * Examples:
 *
 * To retrieve the 5 most recent starred articles:
 *  var url = "http://www.instapaper.com/rss/starred/2/asdfasdfasdf"
 *  $("#instapaper").gmsis(url);
 *
 * To retrieve the 2 most recent starred articles, and show descriptions:
 *  var url = "http://www.instapaper.com/rss/starred/2/asdfasdfasdf"
 *  $("#instapaper").gmsis(url, {count: 2, desc: true});
 *
 *
 * "Easter Egg":
 *  You can also use this script to pull your Unread list and your
 *  Archive list. To do this, just substitute the Unread or Archive RSS
 *  feed for the Starred feed. Everything else is the same.
