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.
