    20    TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION

    21 

    22    1. Definitions.

    23 

    24       "License" shall mean the terms and conditions for use, reproduction,

    25       and distribution as defined by Sections 1 through 9 of this document.

    26 

    27       "Licensor" shall mean the copyright owner or entity authorized by

    28       the copyright owner that is granting the License.

    29 

    30       "Legal Entity" shall mean the union of the acting entity and all

    31       other entities that control, are controlled by, or are under common

    32       control with that entity. For the purposes of this definition,

    33       "control" means (i) the power, direct or indirect, to cause the

    34       direction or management of such entity, whether by contract or

    35       otherwise, or (ii) ownership of fifty percent (50%) or more of the

    36       outstanding shares, or (iii) beneficial ownership of such entity.

    37 

    38       "You" (or "Your") shall mean an individual or Legal Entity

    39       exercising permissions granted by this License.

    40 

    41       "Source" form shall mean the preferred form for making modifications,

    42       including but not limited to software source code, documentation

    43       source, and configuration files.

    44 

    45       "Object" form shall mean any form resulting from mechanical

    46       transformation or translation of a Source form, including but

    47       not limited to compiled object code, generated documentation,

    48       and conversions to other media types.

    49 

    50       "Work" shall mean the work of authorship, whether in Source or

    51       Object form, made available under the License, as indicated by a

    52       copyright notice that is included in or attached to the work

    53       (an example is provided in the Appendix below).

    54 

    55       "Derivative Works" shall mean any work, whether in Source or Object

    56       form, that is based on (or derived from) the Work and for which the

    57       editorial revisions, annotations, elaborations, or other modifications

    58       represent, as a whole, an original work of authorship. For the purposes

    59       of this License, Derivative Works shall not include works that remain

    60       separable from, or merely link (or bind by name) to the interfaces of,

    61       the Work and Derivative Works thereof.

    62 

    63       "Contribution" shall mean any work of authorship, including

    64       the original version of the Work and any modifications or additions

    65       to that Work or Derivative Works thereof, that is intentionally

    66       submitted to Licensor for inclusion in the Work by the copyright owner

    67       or by an individual or Legal Entity authorized to submit on behalf of

    68       the copyright owner. For the purposes of this definition, "submitted"

    69       means any form of electronic, verbal, or written communication sent

    70       to the Licensor or its representatives, including but not limited to

    71       communication on electronic mailing lists, source code control systems,

    72       and issue tracking systems that are managed by, or on behalf of, the

    73       Licensor for the purpose of discussing and improving the Work, but

    74       excluding communication that is conspicuously marked or otherwise

    75       designated in writing by the copyright owner as "Not a Contribution."

    76 

    77       "Contributor" shall mean Licensor and any individual or Legal Entity

    78       on behalf of whom a Contribution has been received by Licensor and

    79       subsequently incorporated within the Work.

    80 

    81    2. Grant of Copyright License. Subject to the terms and conditions of

    82       this License, each Contributor hereby grants to You a perpetual,

    83       worldwide, non-exclusive, no-charge, royalty-free, irrevocable

    84       copyright license to reproduce, prepare Derivative Works of,

    85       publicly display, publicly perform, sublicense, and distribute the

    86       Work and such Derivative Works in Source or Object form.

    87 

    88    3. Grant of Patent License. Subject to the terms and conditions of

    89       this License, each Contributor hereby grants to You a perpetual,

    90       worldwide, non-exclusive, no-charge, royalty-free, irrevocable

    91       (except as stated in this section) patent license to make, have made,

    92       use, offer to sell, sell, import, and otherwise transfer the Work,

    93       where such license applies only to those patent claims licensable

    94       by such Contributor that are necessarily infringed by their

    95       Contribution(s) alone or by combination of their Contribution(s)

    96       with the Work to which such Contribution(s) was submitted. If You

    97       institute patent litigation against any entity (including a

    98       cross-claim or counterclaim in a lawsuit) alleging that the Work

    99       or a Contribution incorporated within the Work constitutes direct

   100       or contributory patent infringement, then any patent licenses

   101       granted to You under this License for that Work shall terminate

   102       as of the date such litigation is filed.

   103 

   104    4. Redistribution. You may reproduce and distribute copies of the

   105       Work or Derivative Works thereof in any medium, with or without

   106       modifications, and in Source or Object form, provided that You

   107       meet the following conditions:

   108 

   109       (a) You must give any other recipients of the Work or

   110           Derivative Works a copy of this License; and

   111 

   112       (b) You must cause any modified files to carry prominent notices

   113           stating that You changed the files; and

   114 

   115       (c) You must retain, in the Source form of any Derivative Works

   116           that You distribute, all copyright, patent, trademark, and

   117           attribution notices from the Source form of the Work,

   118           excluding those notices that do not pertain to any part of

   119           the Derivative Works; and

   120 

   121       (d) If the Work includes a "NOTICE" text file as part of its

   122           distribution, then any Derivative Works that You distribute must

   123           include a readable copy of the attribution notices contained

   124           within such NOTICE file, excluding those notices that do not

   125           pertain to any part of the Derivative Works, in at least one

   126           of the following places: within a NOTICE text file distributed

   127           as part of the Derivative Works; within the Source form or

   128           documentation, if provided along with the Derivative Works; or,

   129           within a display generated by the Derivative Works, if and

   130           wherever such third-party notices normally appear. The contents

   131           of the NOTICE file are for informational purposes only and

   132           do not modify the License. You may add Your own attribution

   133           notices within Derivative Works that You distribute, alongside

   134           or as an addendum to the NOTICE text from the Work, provided

   135           that such additional attribution notices cannot be construed

   136           as modifying the License.

   137 

   138       You may add Your own copyright statement to Your modifications and

   139       may provide additional or different license terms and conditions

   140       for use, reproduction, or distribution of Your modifications, or

   141       for any such Derivative Works as a whole, provided Your use,

   142       reproduction, and distribution of the Work otherwise complies with

   143       the conditions stated in this License.

   144 

   145    5. Submission of Contributions. Unless You explicitly state otherwise,

   146       any Contribution intentionally submitted for inclusion in the Work

   147       by You to the Licensor shall be under the terms and conditions of

   148       this License, without any additional terms or conditions.

   149       Notwithstanding the above, nothing herein shall supersede or modify

   150       the terms of any separate license agreement you may have executed

   151       with Licensor regarding such Contributions.

   152 

   153    6. Trademarks. This License does not grant permission to use the trade

   154       names, trademarks, service marks, or product names of the Licensor,

   155       except as required for reasonable and customary use in describing the

   156       origin of the Work and reproducing the content of the NOTICE file.

   157 

   158    7. Disclaimer of Warranty. Unless required by applicable law or

   159       agreed to in writing, Licensor provides the Work (and each

   160       Contributor provides its Contributions) on an "AS IS" BASIS,

   161       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

   162       implied, including, without limitation, any warranties or conditions

   163       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A

   164       PARTICULAR PURPOSE. You are solely responsible for determining the

   165       appropriateness of using or redistributing the Work and assume any

   166       risks associated with Your exercise of permissions under this License.

   167 

   168    8. Limitation of Liability. In no event and under no legal theory,

   169       whether in tort (including negligence), contract, or otherwise,

   170       unless required by applicable law (such as deliberate and grossly

   171       negligent acts) or agreed to in writing, shall any Contributor be

   172       liable to You for damages, including any direct, indirect, special,

   173       incidental, or consequential damages of any character arising as a

   174       result of this License or out of the use or inability to use the

   175       Work (including but not limited to damages for loss of goodwill,

   176       work stoppage, computer failure or malfunction, or any and all

   177       other commercial damages or losses), even if such Contributor

   178       has been advised of the possibility of such damages.

   179 

   180    9. Accepting Warranty or Additional Liability. While redistributing

   181       the Work or Derivative Works thereof, You may choose to offer,

   182       and charge a fee for, acceptance of support, warranty, indemnity,

   183       or other liability obligations and/or rights consistent with this

   184       License. However, in accepting such obligations, You may act only

   185       on Your own behalf and on Your sole responsibility, not on behalf

   186       of any other Contributor, and only if You agree to indemnify,

   187       defend, and hold each Contributor harmless for any liability

   188       incurred by, or claims asserted against, such Contributor by reason

   189       of your accepting any such warranty or additional liability.

   190 

   191    END OF TERMS AND CONDITIONS
