     14 
     15       "Licensor" shall mean the copyright owner or entity authorized by
     16       the copyright owner that is granting the License.

     19       other entities that control, are controlled by, or are under common
     20       control with that entity. For the purposes of this definition,
     21       "control" means (i) the power, direct or indirect, to cause the
     22       direction or management of such entity, whether by contract or
     23       otherwise, or (ii) ownership of fifty percent (50%) or more of the

     28 
     29       "Source" form shall mean the preferred form for making modifications,
     30       including but not limited to software source code, documentation
     31       source, and configuration files.
     32 
     33       "Object" form shall mean any form resulting from mechanical
     34       transformation or translation of a Source form, including but
     35       not limited to compiled object code, generated documentation,
     36       and conversions to other media types.
     37 
     38       "Work" shall mean the work of authorship, whether in Source or
     39       Object form, made available under the License, as indicated by a
     40       copyright notice that is included in or attached to the work
     41       (an example is provided in the Appendix below).
     42 
     43       "Derivative Works" shall mean any work, whether in Source or Object
     44       form, that is based on (or derived from) the Work and for which the
     45       editorial revisions, annotations, elaborations, or other modifications
     46       represent, as a whole, an original work of authorship. For the purposes
     47       of this License, Derivative Works shall not include works that remain
     48       separable from, or merely link (or bind by name) to the interfaces of,
     49       the Work and Derivative Works thereof.
     50 
     51       "Contribution" shall mean any work of authorship, including
     52       the original version of the Work and any modifications or additions
     53       to that Work or Derivative Works thereof, that is intentionally
     54       submitted to Licensor for inclusion in the Work by the copyright owner
     55       or by an individual or Legal Entity authorized to submit on behalf of
     56       the copyright owner. For the purposes of this definition, "submitted"
     57       means any form of electronic, verbal, or written communication sent
     58       to the Licensor or its representatives, including but not limited to
     59       communication on electronic mailing lists, source code control systems,
     60       and issue tracking systems that are managed by, or on behalf of, the
     61       Licensor for the purpose of discussing and improving the Work, but
     62       excluding communication that is conspicuously marked or otherwise
     63       designated in writing by the copyright owner as "Not a Contribution."
     64 
     65       "Contributor" shall mean Licensor and any individual or Legal Entity
     66       on behalf of whom a Contribution has been received by Licensor and
     67       subsequently incorporated within the Work.
     68 
     69    2. Grant of Copyright License. Subject to the terms and conditions of
     70       this License, each Contributor hereby grants to You a perpetual,
     71       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
     72       copyright license to reproduce, prepare Derivative Works of,
     73       publicly display, publicly perform, sublicense, and distribute the
     74       Work and such Derivative Works in Source or Object form.
     75 
     76    3. Grant of Patent License. Subject to the terms and conditions of
     77       this License, each Contributor hereby grants to You a perpetual,
     78       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
     79       (except as stated in this section) patent license to make, have made,
     80       use, offer to sell, sell, import, and otherwise transfer the Work,
     81       where such license applies only to those patent claims licensable
     82       by such Contributor that are necessarily infringed by their
     83       Contribution(s) alone or by combination of their Contribution(s)
     84       with the Work to which such Contribution(s) was submitted. If You
     85       institute patent litigation against any entity (including a
     86       cross-claim or counterclaim in a lawsuit) alleging that the Work
     87       or a Contribution incorporated within the Work constitutes direct
     88       or contributory patent infringement, then any patent licenses
     89       granted to You under this License for that Work shall terminate
     90       as of the date such litigation is filed.
     91 
     92    4. Redistribution. You may reproduce and distribute copies of the
     93       Work or Derivative Works thereof in any medium, with or without
     94       modifications, and in Source or Object form, provided that You
     95       meet the following conditions:
     96 
     97       (a) You must give any other recipients of the Work or
     98           Derivative Works a copy of this License; and
     99 
    100       (b) You must cause any modified files to carry prominent notices
    101           stating that You changed the files; and
    102 
    103       (c) You must retain, in the Source form of any Derivative Works
    104           that You distribute, all copyright, patent, trademark, and
    105           attribution notices from the Source form of the Work,
    106           excluding those notices that do not pertain to any part of
    107           the Derivative Works; and
    108 
    109       (d) If the Work includes a "NOTICE" text file as part of its
    110           distribution, then any Derivative Works that You distribute must
    111           include a readable copy of the attribution notices contained
    112           within such NOTICE file, excluding those notices that do not
    113           pertain to any part of the Derivative Works, in at least one
    114           of the following places: within a NOTICE text file distributed
    115           as part of the Derivative Works; within the Source form or
    116           documentation, if provided along with the Derivative Works; or,
    117           within a display generated by the Derivative Works, if and
    118           wherever such third-party notices normally appear. The contents
    119           of the NOTICE file are for informational purposes only and
    120           do not modify the License. You may add Your own attribution
    121           notices within Derivative Works that You distribute, alongside
    122           or as an addendum to the NOTICE text from the Work, provided
    123           that such additional attribution notices cannot be construed
    124           as modifying the License.
    125 
    126       You may add Your own copyright statement to Your modifications and
    127       may provide additional or different license terms and conditions
    128       for use, reproduction, or distribution of Your modifications, or
    129       for any such Derivative Works as a whole, provided Your use,
    130       reproduction, and distribution of the Work otherwise complies with
    131       the conditions stated in this License.
    132 
    133    5. Submission of Contributions. Unless You explicitly state otherwise,
    134       any Contribution intentionally submitted for inclusion in the Work
    135       by You to the Licensor shall be under the terms and conditions of
    136       this License, without any additional terms or conditions.
    137       Notwithstanding the above, nothing herein shall supersede or modify
    138       the terms of any separate license agreement you may have executed
    139       with Licensor regarding such Contributions.
    140 
    141    6. Trademarks. This License does not grant permission to use the trade
    142       names, trademarks, service marks, or product names of the Licensor,
    143       except as required for reasonable and customary use in describing the
    144       origin of the Work and reproducing the content of the NOTICE file.
    145 
    146    7. Disclaimer of Warranty. Unless required by applicable law or
    147       agreed to in writing, Licensor provides the Work (and each
    148       Contributor provides its Contributions) on an "AS IS" BASIS,
    149       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    150       implied, including, without limitation, any warranties or conditions
    151       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    152       PARTICULAR PURPOSE. You are solely responsible for determining the
    153       appropriateness of using or redistributing the Work and assume any
    154       risks associated with Your exercise of permissions under this License.
    155 
    156    8. Limitation of Liability. In no event and under no legal theory,
    157       whether in tort (including negligence), contract, or otherwise,
    158       unless required by applicable law (such as deliberate and grossly
    159       negligent acts) or agreed to in writing, shall any Contributor be
    160       liable to You for damages, including any direct, indirect, special,
    161       incidental, or consequential damages of any character arising as a
    162       result of this License or out of the use or inability to use the
    163       Work (including but not limited to damages for loss of goodwill,
    164       work stoppage, computer failure or malfunction, or any and all
    165       other commercial damages or losses), even if such Contributor
    166       has been advised of the possibility of such damages.
    167 
    168    9. Accepting Warranty or Additional Liability. While redistributing
    169       the Work or Derivative Works thereof, You may choose to offer,
    170       and charge a fee for, acceptance of support, warranty, indemnity,
    171       or other liability obligations and/or rights consistent with this
    172       License. However, in accepting such obligations, You may act only
    173       on Your own behalf and on Your sole responsibility, not on behalf
    174       of any other Contributor, and only if You agree to indemnify,
    175       defend, and hold each Contributor harmless for any liability
    176       incurred by, or claims asserted against, such Contributor by reason
    177       of your accepting any such warranty or additional liability.
    178
