40

41
      "Derivative Works" shall mean any work, whether in Source or Object
42
      form, that is based on (or derived from) the Work and for which the
43
      editorial revisions, annotations, elaborations, or other modifications
44
      represent, as a whole, an original work of authorship. For the purposes
45
      of this License, Derivative Works shall not include works that remain
46
      separable from, or merely link (or bind by name) to the interfaces of,
47
      the Work and Derivative Works thereof.
48

49
      "Contribution" shall mean any work of authorship, including
50
      the original version of the Work and any modifications or additions
51
      to that Work or Derivative Works thereof, that is intentionally
52
      submitted to Licensor for inclusion in the Work by the copyright owner

54
      the copyright owner. For the purposes of this definition, "submitted"

62

63
      "Contributor" shall mean Licensor and any individual or Legal Entity
64

   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,
71
      publicly display, publicly perform, sublicense, and distribute the
72
      Work and such Derivative Works in Source or Object form.
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.
