-

-      "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

-      the Work and Derivative Works thereof.

-

-      "Contribution" shall mean any work of authorship, including

-      or by an individual or Legal Entity authorized to submit on behalf of

-      the copyright owner. For the purposes of this definition, "submitted"

-

-      "Contributor" shall mean Licensor and any individual or Legal Entity

-      on behalf of whom a Contribution has been received by Licensor and

-      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,

-      (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.

-
