+// 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.
