| 35 | +in or attached to the work (an example is provided in the Appendix below). | ||
| 36 | + | ||
| 37 | +"Derivative Works" shall mean any work, whether in Source or Object form, that | ||
| 38 | +is based on (or derived from) the Work and for which the editorial revisions, | ||
| 39 | +annotations, elaborations, or other modifications represent, as a whole, an | ||
| 40 | +original work of authorship. For the purposes of this License, Derivative Works | ||
| 41 | +shall not include works that remain separable from, or merely link (or bind by | ||
| 42 | +name) to the interfaces of, the Work and Derivative Works thereof. | ||
| 43 | + | ||
| 44 | +"Contribution" shall mean any work of authorship, including the original version | ||
| 45 | +of the Work and any modifications or additions to that Work or Derivative Works | ||

| 56 | + | ||
| 57 | +"Contributor" shall mean Licensor and any individual or Legal Entity on behalf | ||
| 58 | +of whom a Contribution has been received by Licensor and subsequently | ||

| 60 | + | ||
| 61 | +2. Grant of Copyright License. | ||
| 62 | + | ||
| 63 | +Subject to the terms and conditions of this License, each Contributor hereby | ||
| 64 | +grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, | ||
| 65 | +irrevocable copyright license to reproduce, prepare Derivative Works of, | ||
| 66 | +publicly display, publicly perform, sublicense, and distribute the Work and such | ||
| 67 | +Derivative Works in Source or Object form. | ||
| 68 | + | ||
| 69 | +3. Grant of Patent License. | ||
| 70 | + | ||
| 71 | +Subject to the terms and conditions of this License, each Contributor hereby | ||
| 72 | +grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, | ||
| 73 | +irrevocable (except as stated in this section) patent license to make, have | ||
| 74 | +made, use, offer to sell, sell, import, and otherwise transfer the Work, where | ||
| 75 | +such license applies only to those patent claims licensable by such Contributor | ||
| 76 | +that are necessarily infringed by their Contribution(s) alone or by combination | ||
| 77 | +of their Contribution(s) with the Work to which such Contribution(s) was | ||
| 78 | +submitted. If You institute patent litigation against any entity (including a | ||
| 79 | +cross-claim or counterclaim in a lawsuit) alleging that the Work or a | ||
| 80 | +Contribution incorporated within the Work constitutes direct or contributory | ||
| 81 | +patent infringement, then any patent licenses granted to You under this License | ||
| 82 | +for that Work shall terminate as of the date such litigation is filed. | ||
| 83 | + | ||
| 84 | +4. Redistribution. | ||
| 85 | + | ||
| 86 | +You may reproduce and distribute copies of the Work or Derivative Works thereof | ||
| 87 | +in any medium, with or without modifications, and in Source or Object form, | ||
| 88 | +provided that You meet the following conditions: | ||
| 89 | + | ||
| 90 | +You must give any other recipients of the Work or Derivative Works a copy of | ||
| 91 | +this License; and | ||
| 92 | +You must cause any modified files to carry prominent notices stating that You | ||
| 93 | +changed the files; and | ||
| 94 | +You must retain, in the Source form of any Derivative Works that You distribute, | ||
| 95 | +all copyright, patent, trademark, and attribution notices from the Source form | ||
| 96 | +of the Work, excluding those notices that do not pertain to any part of the | ||
| 97 | +Derivative Works; and | ||
| 98 | +If the Work includes a "NOTICE" text file as part of its distribution, then any | ||
| 99 | +Derivative Works that You distribute must include a readable copy of the | ||
| 100 | +attribution notices contained within such NOTICE file, excluding those notices | ||
| 101 | +that do not pertain to any part of the Derivative Works, in at least one of the | ||
| 102 | +following places: within a NOTICE text file distributed as part of the | ||
| 103 | +Derivative Works; within the Source form or documentation, if provided along | ||
| 104 | +with the Derivative Works; or, within a display generated by the Derivative | ||
| 105 | +Works, if and wherever such third-party notices normally appear. The contents of | ||
| 106 | +the NOTICE file are for informational purposes only and do not modify the | ||
| 107 | +License. You may add Your own attribution notices within Derivative Works that | ||
| 108 | +You distribute, alongside or as an addendum to the NOTICE text from the Work, | ||
| 109 | +provided that such additional attribution notices cannot be construed as | ||
| 110 | +modifying the License. | ||
| 111 | +You may add Your own copyright statement to Your modifications and may provide | ||
| 112 | +additional or different license terms and conditions for use, reproduction, or | ||
| 113 | +distribution of Your modifications, or for any such Derivative Works as a whole, | ||
| 114 | +provided Your use, reproduction, and distribution of the Work otherwise complies | ||
| 115 | +with the conditions stated in this License. | ||
| 116 | + | ||
| 117 | +5. Submission of Contributions. | ||
| 118 | + | ||
| 119 | +Unless You explicitly state otherwise, any Contribution intentionally submitted | ||
| 120 | +for inclusion in the Work by You to the Licensor shall be under the terms and | ||
| 121 | +conditions of this License, without any additional terms or conditions. | ||
| 122 | +Notwithstanding the above, nothing herein shall supersede or modify the terms of | ||
| 123 | +any separate license agreement you may have executed with Licensor regarding | ||
| 124 | +such Contributions. | ||
| 125 | + | ||
| 126 | +6. Trademarks. | ||
| 127 | + | ||
| 128 | +This License does not grant permission to use the trade names, trademarks, | ||
| 129 | +service marks, or product names of the Licensor, except as required for | ||
| 130 | +reasonable and customary use in describing the origin of the Work and | ||
| 131 | +reproducing the content of the NOTICE file. | ||
| 132 | + | ||
| 133 | +7. Disclaimer of Warranty. | ||
| 134 | + | ||
| 135 | +Unless required by applicable law or agreed to in writing, Licensor provides the | ||
| 136 | +Work (and each Contributor provides its Contributions) on an "AS IS" BASIS, | ||
| 137 | +WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, | ||
| 138 | +including, without limitation, any warranties or conditions of TITLE, | ||
| 139 | +NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are | ||
| 140 | +solely responsible for determining the appropriateness of using or | ||
| 141 | +redistributing the Work and assume any risks associated with Your exercise of | ||
| 142 | +permissions under this License. | ||
| 143 | + | ||
| 144 | +8. Limitation of Liability. | ||
| 145 | + | ||
| 146 | +In no event and under no legal theory, whether in tort (including negligence), | ||
| 147 | +contract, or otherwise, unless required by applicable law (such as deliberate | ||
| 148 | +and grossly negligent acts) or agreed to in writing, shall any Contributor be | ||
| 149 | +liable to You for damages, including any direct, indirect, special, incidental, | ||
| 150 | +or consequential damages of any character arising as a result of this License or | ||
| 151 | +out of the use or inability to use the Work (including but not limited to | ||
| 152 | +damages for loss of goodwill, work stoppage, computer failure or malfunction, or | ||
| 153 | +any and all other commercial damages or losses), even if such Contributor has | ||
| 154 | +been advised of the possibility of such damages. | ||
| 155 | + | ||
| 156 | +9. Accepting Warranty or Additional Liability. | ||
| 157 | + | ||
| 158 | +While redistributing the Work or Derivative Works thereof, You may choose to | ||
| 159 | +offer, and charge a fee for, acceptance of support, warranty, indemnity, or | ||
| 160 | +other liability obligations and/or rights consistent with this License. However, | ||
| 161 | +in accepting such obligations, You may act only on Your own behalf and on Your | ||
| 162 | +sole responsibility, not on behalf of any other Contributor, and only if You | ||
| 163 | +agree to indemnify, defend, and hold each Contributor harmless for any liability | ||
| 164 | +incurred by, or claims asserted against, such Contributor by reason of your | ||
| 165 | +accepting any such warranty or additional liability. | ||
| 166 | + | ||
| 167 | +END OF TERMS AND CONDITIONS | ||
| 168 | + | ||
| 169 | +APPENDIX: How to apply the Apache License to your work | ||
| 170 | + | ||
| 171 | +To apply the Apache License to your work, attach the following boilerplate | ||

| 175 | +recommend that a file or class name and description of purpose be included on | ||
| 176 | +the same "printed page" as the copyright notice for easier identification within | ||
| 177 | +third-party archives. | ||
