+---
+This directory contains code for binding the test262 test suite
+into the v8 test harness. To use the tests check out the test262
+tests from
+
+  http://hg.ecmascript.org/tests/test262
+
+at revision 334 as 'data' in this directory.  Using later version
+may be possible but the tests are only known to pass (and indeed run)
+with that revision.
+
+hg clone -r 334 http://hg.ecmascript.org/tests/test262 data
+
+If you do update to a newer revision you may have to change the test
+harness adapter code since it uses internal functionality from the
+harness that comes bundled with the tests.  You will most likely also
+have to update the test expectation file.
