   *     "Work" shall mean the work of authorship, whether in Source or

   *
   *     "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

   *  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

   *     (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.
   *
