| // (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 | ||

| // the Work and Derivative Works thereof. | ||
|
|
||
| // "Contribution" shall mean any work of authorship, including | ||

| // 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, | ||

| // 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 | ||
