        TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION

        1. Definitions.

        "License" shall mean the terms and conditions for use, reproduction, and 
        distribution as defined by Sections 1 through 9 of this document.

        "Licensor" shall mean the copyright owner or entity authorized by the copyright 
        owner that is granting the License.

        "Legal Entity" shall mean the union of the acting entity and all other entities 
        that control, are controlled by, or are under common control with that entity. 
        For the purposes of this definition, "control" means (i) the power, direct or 
        indirect, to cause the direction or management of such entity, whether by 
        contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the 
        outstanding shares, or (iii) beneficial ownership of such entity.

        "You" (or "Your") shall mean an individual or Legal Entity exercising 
        permissions granted by this License.

        "Source" form shall mean the preferred form for making modifications, including 
        but not limited to software source code, documentation source, and configuration 
        files.

        "Object" form shall mean any form resulting from mechanical transformation or 
        translation of a Source form, including but not limited to compiled object code, 
        generated documentation, and conversions to other media types.

        "Work" shall mean the work of authorship, whether in Source or Object form, made 
        available under the License, as indicated by a copyright notice that is included 
        in or attached to the work (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 represent, as a whole, an 
        original work of authorship. For the purposes of this License, Derivative Works 
        shall not include works that remain separable from, or merely link (or bind by 
        name) to the interfaces of, the Work and Derivative Works thereof.

        "Contribution" shall mean any work of authorship, 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 by an individual or Legal Entity authorized to submit 
        on behalf of the copyright owner. For the purposes of this definition, 
        "submitted" means any form of electronic, verbal, or written communication sent 
        to the Licensor or its representatives, including but not limited to 
        communication on electronic mailing lists, source code control systems, and 
        issue tracking systems that are managed by, or on behalf of, the Licensor for 
        the purpose of discussing and improving the Work, but excluding communication 
        that is conspicuously marked or otherwise designated in writing by the copyright 
        owner as "Not a Contribution."

        "Contributor" shall mean Licensor and any individual or Legal Entity on behalf 
        of whom a Contribution has been received by Licensor and subsequently 
        incorporated within the Work.

        2. Grant of Copyright 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 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, use, offer to sell, sell, import, and otherwise transfer the Work, where 
        such license applies only to those patent claims licensable 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:

        You must give any other recipients of the Work or Derivative Works a copy of 
        this License; and You must cause any modified files to carry prominent notices 
        stating that You changed the files; and 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 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
      

The Apache websites recommends the following approach to applying the Apache license to your work.

To apply the Apache License to your work, attach the following boilerplate notice, with the fields enclosed by brackets "[]" replaced with your own identifying information. (Don't include the brackets!) The text should be enclosed in the appropriate comment syntax for the file format. We also recommend that a file or class name and description of purpose be included on the same "printed page" as the copyright notice for easier identification within third-party archives.
