+TestRuntest.py:  a testing framework for the runtest.py command used to
+invoke SCons tests.
+
+A TestRuntest environment object is created via the usual invocation:
+
+    test = TestRuntest()
+
+TestRuntest is a subclass of TestCommon, which is in turn is a subclass
+of TestCmd), and hence has available all of the methods and attributes
+from those classes, as well as any overridden or additional methods or
+attributes defined in this subclass.
