-	   "Object" form shall mean any form resulting from mechanical
-	   transformation or translation of a Source form, including but
-	   not limited to compiled object code, generated documentation,
-	   and conversions to other media types.
-	   "Work" shall mean the work of authorship, whether in Source or
-	   Object form, made available under the License, as indicated by a
-	   copyright notice that is included in or attached to the work
-	   (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
-	   the original version of the Work and any modifications or additions
-	   to that Work or Derivative Works thereof, that is intentionally
-	   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"
-	   means any form of electronic, verbal, or written communication sent
-	   to the Licensor or its representatives, including but not limited to
-	   communication on electronic mailing lists, source code control systems,
-	   and issue tracking systems that are managed by, or on behalf of, the
-	   Licensor for the purpose of discussing and improving the Work, but

-	   designated in writing by the copyright owner as "Not a Contribution."
-	   "Contributor" shall mean Licensor and any individual or Legal Entity
-	   on behalf of whom a Contribution has been received by Licensor and
-	   subsequently incorporated within the Work.
-	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
