+``REPEAT <mode>:<n>``
+  Run tests repeatedly based on the given ``<mode>`` up to ``<n>`` times.
+  The modes are:
+
+  ``UNTIL_FAIL``
+    Require each test to run ``<n>`` times without failing in order to pass.
+    This is useful in finding sporadic failures in test cases.
+
+  ``UNTIL_PASS``
+    Allow each test to run up to ``<n>`` times in order to pass.
+    Repeats tests if they fail for any reason.
+    This is useful in tolerating sporadic failures in test cases.
+
+  ``AFTER_TIMEOUT``
+    Allow each test to run up to ``<n>`` times in order to pass.
+    Repeats tests only if they timeout.
+    This is useful in tolerating sporadic timeouts in test cases
+    on busy machines.
+
 ``SCHEDULE_RANDOM <ON|OFF>``
   Launch tests in a random order.  This may be useful for detecting
   implicit test dependencies.
