+// Utility script for writing worker tests. In your main document do:
+//
+// <script type="text/javascript" src="worker_driver.js"></script>
+// <script type="text/javascript">
+// workerTestExec('myWorkerTestCase.js')
+// </script>
+//
+// This will then spawn a worker, define some utility functions, and then
+// execute the code in myWorkerTestCase.js. You can then use these
+// functions in your worker-side test:
+//
+// ok() - like the SimpleTest assert
+// is() - like the SimpleTest assert
+// workerTestDone() - like SimpleTest.finish() indicating the test is complete
+//
+// There are also some functions for requesting information that requires
+// SpecialPowers or other main-thread-only resources:
+//
+// workerTestGetVersion() - request the current version string from the MT
+// workerTestGetUserAgent() - request the user agent string from the MT
+// workerTestGetOSCPU() - request the navigator.oscpu string from the MT
+//
+// For an example see test_worker_interfaces.html and test_worker_interfaces.js.
