+This is a local copy of the WebGL conformance suite, version 1.0.1, SVN revision 17794 (on the 1.0.1 branch, not on trunk)
+
+The canonical location for this 1.0.1 test suite is:
+
+  https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/conformance-suites/1.0.1
+
+The canonical location of the development tree is:
+
+  https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/tests
+
+All files and directories in this directory, with the exceptions listed below, come from
+upstream and should not be modified without corresponding upstream fixes and/or a
+patch file in this directory. The exceptions (the Mozilla-specific files) are:
+ * README.mozilla (this file)
+ * failing_tests_*.txt
+ * moz.build
+ * writemanifest.py
+ * *.patch files, if any
+
+How to do an update:
+ 1. unapply local patches (the .patch files here)
+ 2. perform the update:
+   * method A: apply diff with new version
+   * method B: erase all files here, import copy of new version.
+ 3. edit CONFORMANCE_TEST_VERSION in test_webgl_conformance_test_suite.html. That's what
+    determines with tests to run, as some tests are only enabled in some not-yet-released
+    version.
+ 4. reapply local patches.
+ 5. update this readme and the .patch files.
+ 6. run writemanifest.py to update test manifest.
