- "Derivative Works" shall mean any work, whether in Source or Object\r
- form, that is based on (or derived from) the Work and for which the\r
- editorial revisions, annotations, elaborations, or other modifications\r
- represent, as a whole, an original work of authorship. For the purposes\r
- of this License, Derivative Works shall not include works that remain\r
- separable from, or merely link (or bind by name) to the interfaces of,\r

-\r
- 2. Grant of Copyright License. Subject to the terms and conditions of\r
- this License, each Contributor hereby grants to You a perpetual,\r
- worldwide, non-exclusive, no-charge, royalty-free, irrevocable\r
- copyright license to reproduce, prepare Derivative Works of,\r

- worldwide, non-exclusive, no-charge, royalty-free, irrevocable\r
- (except as stated in this section) patent license to make, have made,\r
- use, offer to sell, sell, import, and otherwise transfer the Work,\r
- where such license applies only to those patent claims licensable\r
- by such Contributor that are necessarily infringed by their\r
- Contribution(s) alone or by combination of their Contribution(s)\r
- with the Work to which such Contribution(s) was submitted. If You\r
- institute patent litigation against any entity (including a\r
- cross-claim or counterclaim in a lawsuit) alleging that the Work\r
- or a Contribution incorporated within the Work constitutes direct\r
- or contributory patent infringement, then any patent licenses\r
- granted to You under this License for that Work shall terminate\r
- as of the date such litigation is filed.\r
-\r
- 4. Redistribution. You may reproduce and distribute copies of the\r
- Work or Derivative Works thereof in any medium, with or without\r
- modifications, and in Source or Object form, provided that You\r
- meet the following conditions:\r
-\r
- (a) You must give any other recipients of the Work or\r
- Derivative Works a copy of this License; and\r
-\r
- (b) You must cause any modified files to carry prominent notices\r
- stating that You changed the files; and\r
-\r
- (c) You must retain, in the Source form of any Derivative Works\r
- that You distribute, all copyright, patent, trademark, and\r
- attribution notices from the Source form of the Work,\r
- excluding those notices that do not pertain to any part of\r
- the Derivative Works; and\r
-\r
- (d) If the Work includes a "NOTICE" text file as part of its\r
- distribution, then any Derivative Works that You distribute must\r
- include a readable copy of the attribution notices contained\r
- within such NOTICE file, excluding those notices that do not\r
- pertain to any part of the Derivative Works, in at least one\r
- of the following places: within a NOTICE text file distributed\r
- as part of the Derivative Works; within the Source form or\r
- documentation, if provided along with the Derivative Works; or,\r
- within a display generated by the Derivative Works, if and\r
- wherever such third-party notices normally appear. The contents\r
- of the NOTICE file are for informational purposes only and\r
- do not modify the License. You may add Your own attribution\r
- notices within Derivative Works that You distribute, alongside\r
- or as an addendum to the NOTICE text from the Work, provided\r
- that such additional attribution notices cannot be construed\r
- as modifying the License.\r
-\r
- You may add Your own copyright statement to Your modifications and\r
- may provide additional or different license terms and conditions\r
- for use, reproduction, or distribution of Your modifications, or\r
- for any such Derivative Works as a whole, provided Your use,\r
- reproduction, and distribution of the Work otherwise complies with\r
- the conditions stated in this License.\r
-\r
- 5. Submission of Contributions. Unless You explicitly state otherwise,\r
- any Contribution intentionally submitted for inclusion in the Work\r
- by You to the Licensor shall be under the terms and conditions of\r
- this License, without any additional terms or conditions.\r
- Notwithstanding the above, nothing herein shall supersede or modify\r
- the terms of any separate license agreement you may have executed\r
- with Licensor regarding such Contributions.\r
-\r
- 6. Trademarks. This License does not grant permission to use the trade\r
- names, trademarks, service marks, or product names of the Licensor,\r
- except as required for reasonable and customary use in describing the\r
- origin of the Work and reproducing the content of the NOTICE file.\r
-\r
- 7. Disclaimer of Warranty. Unless required by applicable law or\r
- agreed to in writing, Licensor provides the Work (and each\r
- Contributor provides its Contributions) on an "AS IS" BASIS,\r
- WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or\r
- implied, including, without limitation, any warranties or conditions\r
- of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A\r
- PARTICULAR PURPOSE. You are solely responsible for determining the\r
- appropriateness of using or redistributing the Work and assume any\r
- risks associated with Your exercise of permissions under this License.\r
-\r
- 8. Limitation of Liability. In no event and under no legal theory,\r
- whether in tort (including negligence), contract, or otherwise,\r
- unless required by applicable law (such as deliberate and grossly\r
- negligent acts) or agreed to in writing, shall any Contributor be\r
- liable to You for damages, including any direct, indirect, special,\r
- incidental, or consequential damages of any character arising as a\r
- result of this License or out of the use or inability to use the\r
- Work (including but not limited to damages for loss of goodwill,\r
- work stoppage, computer failure or malfunction, or any and all\r
- other commercial damages or losses), even if such Contributor\r
- has been advised of the possibility of such damages.\r
-\r
- 9. Accepting Warranty or Additional Liability. While redistributing\r
- the Work or Derivative Works thereof, You may choose to offer,\r
- and charge a fee for, acceptance of support, warranty, indemnity,\r
- or other liability obligations and/or rights consistent with this\r
- License. However, in accepting such obligations, You may act only\r
- on Your own behalf and on Your sole responsibility, not on behalf\r
- of any other Contributor, and only if You agree to indemnify,\r
- defend, and hold each Contributor harmless for any liability\r
- incurred by, or claims asserted against, such Contributor by reason\r
- of your accepting any such warranty or additional liability.\r
-\r
- END OF TERMS AND CONDITIONS\r
-\r
