-// The test scrubber cleans up machine state between tests.  This includes
-// killing all Internet Explorer processes, killing all Chrome processes spawned
-// by Chrome Frame, and deleting the user data directory.  The scrubber must be
-// installed before tests are run via |InstallTestScrubber|.
-//
-// Tests that lead to Chrome using a user data directory other than that used by
-// Chrome Frame in IE must provide that directory to the scrubber via
-// |OverrideDataDirectoryForThisTest()|.  Failure to do so will lead to the
-// scrubber failing to delete that directory.
