 * Works in all A-grade browsers, including IE6.
 * The plugin automatically checks if the browser natively supports the HTML5 `placeholder` attribute for `input` and `textarea` elements. If this is the case, the plugin won’t do anything. If `@placeholder` is only supported for `input` elements, the plugin will leave those alone and apply to `textarea`s exclusively. (This is the case for Safari 4, Opera 11.00, and possibly other browsers.)
+* The plugin will cache the results of its two feature tests in `jQuery.fn.placeholder.input` and `jQuery.fn.placeholder.placeholder`. For example, if `@placeholder` is natively supported for `input` elements, `jQuery.fn.placeholder.input` will be `true`. After loading the plugin, you can re-use these properties in your own code.
