   "Legal Entity" shall mean the union of the acting entity and all

   other entities that control, are controlled by, or are under common

   source, and configuration files.

   "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

   excluding communication that is conspicuously marked or otherwise

   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.
