+Graded Browser Support
+---------
+One useful feature of Bowser is that aside from checking one browser from another -- it will keep up to date with [Yahoo's Graded Browser Support](http://developer.yahoo.com/yui/articles/gbs/) chart, giving you access to each grade on the bowser object

+``` js
+if (bowser.a) {
+  // support full feature set

+else if (bowser.c) {
+  // serve degraded version
+}
+else {
+  // unsupported (bowser.x)
