+ Object form, made available under the License, as indicated by a\r
+ copyright notice that is included in or attached to the work\r

+ "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

+ 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

+ APPENDIX: How to apply the Apache License to your work.\r

+ boilerplate notice, with the fields enclosed by brackets "[]"\r
