'Derivative Works' means any works, whether in source or object form, that are based on (or derived from) the Work and for which the editorial revisions, annotations, elaborations or other modifications collectively constitute a separate work. For purposes of this License, Derivative Works do not include works that remain separable from the Work and its Derivative Works or are merely linked (or associated by name) with their interfaces.

'Contribution' means any work, including the original version of the Work and any modifications or additions to that Work or derivative works thereof, that is intentionally submitted to Licensor for inclusion in the Work by the Copyright Owner or any person or entity authorized to submit on behalf of the Copyright Owner. For purposes of this definition, "submitted" means any form of electronic, oral, or written communication sent to Licensor or its agents, including, but not limited to, communications via electronic mailing lists, source code control systems, and issue tracking systems maintained by or on behalf of Licensor for the purpose of discussing and improving the Work, but excluding communications clearly marked as "o".

'Contributor' means the Licensor and any natural or legal person on whose behalf a Contribution has been received by the Licensor and subsequently incorporated into the Work.

Subject to the terms of this License, each Contributor hereby grants you a perpetual, worldwide, non-exclusive, royalty-free, royalty-free and 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.

Subject to the terms and conditions of this License, each Contributor hereby grants to You a perpetual, worldwide, non-exclusive, royalty-free, irrevocable (except as provided in this section) patent license to make, have made, use, offer to sell, sell, import and otherwise transfer the Work, which license applies only to those patent claims that can be licensed by such contributor and that are necessarily infringed by such contributor’s contribution(s) alone or by the combination of such contributor’s contribution(s) with the work for which such contribution(s) was filed. If you initiate a patent suit against an entity (including a counterclaim or cross-claim in a lawsuit) alleging that the work or a contribution incorporated in the work constitutes direct or contributory patent infringement, all patent licenses granted to you under this License for that work will terminate as of the date of initiation of that suit.

You may reproduce and distribute copies of the Work or derivative works in any medium, with or without modification, in source or object form, provided that you comply with the following conditions:

You may add your own copyright notice to your modifications and set additional or different license terms for the use, copying or distribution of your modifications or for such derivative works as a whole, provided that your use, copying and distribution of the work otherwise complies with the terms set forth in this License.

Unless you expressly state otherwise, all Contributions that you intentionally submit to Licensor for inclusion in the Work are subject to the terms of this License, without any additional terms. Notwithstanding the foregoing, nothing in this document supersedes or modifies the terms of any separate license agreement you may have entered into with Licensor with respect to such Contributions.

This license does not grant permission to use Licensor’s trade names, trademarks, service marks or product names except as necessary for fair and customary use in describing the source of the work and reproducing the contents of the NOTICE file.

Except as required by applicable law or agreed to in writing, Licensor provides the Work (and each Contributor’s Contributions) "as is" without any express or implied warranties or conditions, including, but not limited to, 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 all risks associated with exercising your rights under this license.

Under no circumstances and under no legal theory, whether in tort (including negligence), contract or otherwise, shall any contributor be liable to you for any damages, including direct, indirect, special, incidental or consequential damages of any kind arising out of this license or out of the use of or inability to use the work (including, but not limited to, damages for loss of goodwill, work stoppage, computer failure or malfunction, or any other commercial damage or loss), even if such contributor has been advised of the possibility of such damages.

In redistributing the Work or Derivative Works, you may choose to offer support, warranty, indemnification or other liability obligations and/or rights in accordance with this License and charge a fee for doing so. However, in assuming such obligations, you may act only on your own behalf and at your sole risk, not on behalf of other contributors, and only if you agree to indemnify, defend and hold harmless each contributor for all liabilities incurred by it as a result of your assumption of such warranty or additional liability or for any claims asserted against it.
