    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

    verbal, or written communication sent to the Licensor or its representatives,
    including but not limited to communication on electronic mailing lists,

    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:

   1. You must give any other recipients of the Work or Derivative Works a copy
      of this License; and

   2. You must cause any modified files to carry prominent notices stating that
      You changed the files; and

   3. 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

   4. 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.
