+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but

+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"

+README FOR BROWSERSCOPE
+-----------------------
+
+Hey there - thanks for downloading the code. This file has instructions
+for getting setup so that you can run the codebase locally.
+
+This project is built on Google App Engine using the
+Django web application framework and written in Python.
+
+To get started, you'll need to first download the App Engine SDK at:
+http://code.google.com/appengine/downloads.html
+
+For local development, just startup the server:
+./pathto/google_appengine/dev_appserver.py --port=8080 browserscope
+
+You should then be able to access the local application at:
+http://localhost:8080/
+
+Note: the first time you hit the homepage it may take a little
+while - that's because it's trying to read out median times for all
+of the tests from a nonexistent datastore and write to memcache.
+Just be a lil patient.
+
+You can run the unit tests at:
+  http://localhost:8080/test
+
+
+CONTRIBUTING
+------------------
+
+Most likely you are interested in adding new tests or creating
+a new test category. If you are interested in adding tests to an existing
+"category" you may want to get in touch with the maintainer for that
+branch of the tree. We are really looking forward to receiving your
+code in patch format. Currently the category maintainers are:
+Network: Steve Souders <souders@gmail.com>
+Reflow: Lindsey Simon <elsigh@gmail.com>
+Security: Adam Barth <adam@adambarth.com> and Collin Jackson <collin@collinjackson.com>
+
+
+To create a completely new test category:
+  * Copy one of the existing directories in categories/
+  * Edit your test_set.py, handlers.py
+  * Add your files in templates/ and static/
+  * Update urls.py and settings.CATEGORIES
+  * Follow the examples of other tests re:
+      * beaconing using/testdriver_base
+      * your GetScoreAndDisplayValue method
+      * your GetRowScoreAndDisplayValue method
+
+References:

+The BrowserScope project provides a set of cross-browser HTML editor tests,
+which we import in our test suite in order to run them as part of our
+continuous integration system.
+
+We pull tests occasionally from their Subversion repository using the pull
+script which can be found in this directory.  We also record the revision ID
+which we've used in the current_revision file inside this directory.
+
+Using the pull script is quite easy, just switch to this directory, and say:
+
+sh update_from_upstream
+
+There are tests which we're currently failing on, and there will probably be
+more of those in the future.  We should maintain a list of the failing tests
+manually in currentStatus.js (which can also be found in this directory), to
+make sure that the suite passes entirely, with failing tests marked as todo
+items.

+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its

+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and

+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.

+README FOR BROWSERSCOPE
+-----------------------
+
+Hey there - thanks for downloading the code. This file has instructions
+for getting setup so that you can run the codebase locally.
+
+This project is built on Google App Engine using the
+Django web application framework and written in Python.
+
+To get started, you'll need to first download the App Engine SDK at:
+http://code.google.com/appengine/downloads.html
+
+For local development, just startup the server:
+./pathto/google_appengine/dev_appserver.py --port=8080 browserscope
+
+You should then be able to access the local application at:
+http://localhost:8080/
+
+Note: the first time you hit the homepage it may take a little
+while - that's because it's trying to read out median times for all
+of the tests from a nonexistent datastore and write to memcache.
+Just be a lil patient.
+
+You can run the unit tests at:
+  http://localhost:8080/test
+
+
+CONTRIBUTING
+------------------
+
+Most likely you are interested in adding new tests or creating
+a new test category. If you are interested in adding tests to an existing
+"category" you may want to get in touch with the maintainer for that
+branch of the tree. We are really looking forward to receiving your
+code in patch format. Currently the category maintainers are:
+Network: Steve Souders <souders@gmail.com>
+Reflow: Lindsey Simon <elsigh@gmail.com>
+Security: Adam Barth <adam@adambarth.com> and Collin Jackson <collin@collinjackson.com>
+
+
+To create a completely new test category:
+  * Copy one of the existing directories in categories/
+  * Edit your test_set.py, handlers.py
+  * Add your files in templates/ and static/
+  * Update urls.py and settings.CATEGORIES
+  * Follow the examples of other tests re:
+      * beaconing using/testdriver_base
+      * your GetScoreAndDisplayValue method
+      * your GetRowScoreAndDisplayValue method
+

+The BrowserScope project provides a set of cross-browser HTML editor tests,
+which we import in our test suite in order to run them as part of our
+continuous integration system.
+
+We pull tests occasionally from their Subversion repository using the pull
+script which can be found in this directory.  We also record the revision ID
+which we've used in the current_revision file inside this directory.
+
+Using the pull script is quite easy, just switch to this directory, and say:
+
+sh update_from_upstream
+
+There are tests which we're currently failing on, and there will probably be
+more of those in the future.  We should maintain a list of the failing tests
+manually in currentStatus.js (which can also be found in this directory), to
+make sure that the suite passes entirely, with failing tests marked as todo
+items.
+
+The current status of the test suite needs to be updated whenever an editor
+bug gets fixed, which makes us pass one of the tests.  When that happens,
+you should set the UPDATE_TEST_RESULTS constant to true in test_richtext2.html,
+run the test suite, paste the result JSON string in a JSON beautifier (such
+as http://jsbeautifier.org/), and use the result to update currentStatus.js.
+
+As a special case, if there are platform-specific failures, these are instead
+recorded manually in platformFailures.js. (Currently, this applies only to
+tests that are dependent on underlying platform support for the Thai script.)
