mas01mj@732:      * This example was created to illustrate how one can build an synchronous
mas01mj@732:      * TestCase - one that relies on remote data of some sort.
mas01mj@732:      * This use case is now diminished by the creation of E4X and easily
mas01mj@732:      * readable/editable XML data directly in source form.
mas01mj@732:      * But asynchronous tests will probably need to be built at some point
mas01mj@732:      * by somebody... If you're them, maybe you can use this as a template.
