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

|
|
|
48

|
|
|
60 excluding communication that is conspicuously marked or otherwise

66
|
|
|
67 2. Grant of Copyright License. Subject to the terms and conditions of
|
|
|
68 this License, each Contributor hereby grants to You a perpetual,
|
|
|
69 worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
|
|
70 copyright license to reproduce, prepare Derivative Works of,
|
|

|
73
|
|
|
74 3. Grant of Patent License. Subject to the terms and conditions of
|
|
|
75 this License, each Contributor hereby grants to You a perpetual,
|
|
|
76 worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
|
|
77 (except as stated in this section) patent license to make, have made,
|
|
|
78 use, offer to sell, sell, import, and otherwise transfer the Work,
|
|
|
79 where such license applies only to those patent claims licensable
|
|
|
80 by such Contributor that are necessarily infringed by their
|
|
|
81 Contribution(s) alone or by combination of their Contribution(s)
|
|
|
82 with the Work to which such Contribution(s) was submitted. If You
|
|
|
83 institute patent litigation against any entity (including a
|
|
|
84 cross-claim or counterclaim in a lawsuit) alleging that the Work
|
|
|
85 or a Contribution incorporated within the Work constitutes direct
|
|
|
86 or contributory patent infringement, then any patent licenses
|
|
|
87 granted to You under this License for that Work shall terminate
|
|
|
88 as of the date such litigation is filed.
|
|
|
89
|
|
|
90 4. Redistribution. You may reproduce and distribute copies of the
|
|
|
91 Work or Derivative Works thereof in any medium, with or without
|
|
|
92 modifications, and in Source or Object form, provided that You
|
|
|
93 meet the following conditions:
|
|
|
94
|
|
|
95 (a) You must give any other recipients of the Work or
|
|
|
96 Derivative Works a copy of this License; and
|
|
|
97
|
|
|
98 (b) You must cause any modified files to carry prominent notices
|
|
|
99 stating that You changed the files; and
|
|
|
100
|
|
|
101 (c) You must retain, in the Source form of any Derivative Works
|
|
|
102 that You distribute, all copyright, patent, trademark, and
|
|
|
103 attribution notices from the Source form of the Work,
|
|
|
104 excluding those notices that do not pertain to any part of
|
|
|
105 the Derivative Works; and
|
|
|
106
|
|
|
107 (d) If the Work includes a "NOTICE" text file as part of its
|
|
|
108 distribution, then any Derivative Works that You distribute must
|
|
|
109 include a readable copy of the attribution notices contained
|
|
|
110 within such NOTICE file, excluding those notices that do not
|
|
|
111 pertain to any part of the Derivative Works, in at least one
|
|
|
112 of the following places: within a NOTICE text file distributed
|
|
|
113 as part of the Derivative Works; within the Source form or
|
|
|
114 documentation, if provided along with the Derivative Works; or,
|
|
|
115 within a display generated by the Derivative Works, if and
|
|
|
116 wherever such third-party notices normally appear. The contents
|
|
|
117 of the NOTICE file are for informational purposes only and
|
|
|
118 do not modify the License. You may add Your own attribution
|
|
|
119 notices within Derivative Works that You distribute, alongside
|
|
|
120 or as an addendum to the NOTICE text from the Work, provided
|
|
|
121 that such additional attribution notices cannot be construed
|
|
|
122 as modifying the License.
|
|
|
123
|
|
|
124 You may add Your own copyright statement to Your modifications and
|
|
|
125 may provide additional or different license terms and conditions
|
|
|
126 for use, reproduction, or distribution of Your modifications, or
|
|
|
127 for any such Derivative Works as a whole, provided Your use,
|
|
|
128 reproduction, and distribution of the Work otherwise complies with
|
|
|
129 the conditions stated in this License.
|
|
|
130
|
|
|
131 5. Submission of Contributions. Unless You explicitly state otherwise,
|
|
|
132 any Contribution intentionally submitted for inclusion in the Work
|
|
|
133 by You to the Licensor shall be under the terms and conditions of
|
|
|
134 this License, without any additional terms or conditions.
|
|
|
135 Notwithstanding the above, nothing herein shall supersede or modify
|
|
|
136 the terms of any separate license agreement you may have executed
|
|
|
137 with Licensor regarding such Contributions.
|
|
|
138
|
|
|
139 6. Trademarks. This License does not grant permission to use the trade
|
|
|
140 names, trademarks, service marks, or product names of the Licensor,
|
|
|
141 except as required for reasonable and customary use in describing the
|
|
|
142 origin of the Work and reproducing the content of the NOTICE file.
|
|
|
143
|
|
|
144 7. Disclaimer of Warranty. Unless required by applicable law or
|
|
|
145 agreed to in writing, Licensor provides the Work (and each
|
|
|
146 Contributor provides its Contributions) on an "AS IS" BASIS,
|
|
|
147 WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
|
|
148 implied, including, without limitation, any warranties or conditions
|
|
|
149 of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
|
|
150 PARTICULAR PURPOSE. You are solely responsible for determining the
|
|
|
151 appropriateness of using or redistributing the Work and assume any
|
|
|
152 risks associated with Your exercise of permissions under this License.
|
|
|
153
|
|
|
154 8. Limitation of Liability. In no event and under no legal theory,
|
|
|
155 whether in tort (including negligence), contract, or otherwise,
|
|
|
156 unless required by applicable law (such as deliberate and grossly
|
|
|
157 negligent acts) or agreed to in writing, shall any Contributor be
|
|
|
158 liable to You for damages, including any direct, indirect, special,
|
|
|
159 incidental, or consequential damages of any character arising as a
|
|
|
160 result of this License or out of the use or inability to use the
|
|
|
161 Work (including but not limited to damages for loss of goodwill,
|
|
|
162 work stoppage, computer failure or malfunction, or any and all
|
|
|
163 other commercial damages or losses), even if such Contributor
|
|
|
164 has been advised of the possibility of such damages.
|
|
|
165
|
|
|
166 9. Accepting Warranty or Additional Liability. While redistributing
|
|
|
167 the Work or Derivative Works thereof, You may choose to offer,
|
|
|
168 and charge a fee for, acceptance of support, warranty, indemnity,
|
|
|
169 or other liability obligations and/or rights consistent with this
|
|
|
170 License. However, in accepting such obligations, You may act only
|
|
|
171 on Your own behalf and on Your sole responsibility, not on behalf
|
|
|
172 of any other Contributor, and only if You agree to indemnify,
|
|
|
173 defend, and hold each Contributor harmless for any liability
|
|
|
174 incurred by, or claims asserted against, such Contributor by reason
|
|
|
175 of your accepting any such warranty or additional liability.
