Distribution of a Larger Work 186 | 187 | You may create and distribute a Larger Work under terms of Your choice, 188 | provided that You also comply with the requirements of this License for 189 | the Covered Software. If the Larger Work is a combination of Covered 190 | Software with a work governed by one or more Secondary Licenses, and the 191 | Covered Software is not Incompatible With Secondary Licenses, this 192 | License permits You to additionally distribute such Covered Software 193 | under the terms of such Secondary License(s), so that the recipient of 194 | the Larger Work may, at their option, further distribute the Covered 195 | Software under the terms of either this License or such Secondary 196 | License(s). 197 | 198 | 3.4. Notices 199 | 200 | You may not remove or alter the substance of any license notices 201 | (including copyright notices, patent notices, disclaimers of warranty, 202 | or limitations of liability) contained within the Source Code Form of 203 | the Covered Software, except that You may alter any license notices to 204 | the extent required to remedy known factual inaccuracies. 205 | 206 | 3.5.

You must make it absolutely clear that any 212 | such warranty, support, indemnity, or liability obligation is offered by 213 | You alone, and You hereby agree to indemnify every Contributor for any 214 | liability incurred by such Contributor as a result of warranty, support, 215 | indemnity or liability terms You offer.

Termination 233 | -------------- 234 | 235 | 5.1. The rights granted under this License will terminate automatically 236 | if You fail to comply with any of its terms. However, if You become 237 | compliant, then the rights granted under this License from a particular 238 | Contributor are reinstated (a) provisionally, unless and until such 239 | Contributor explicitly and finally terminates Your grants, and (b) on an 240 | ongoing basis, if such Contributor fails to notify You of the 241 | non-compliance by some reasonable means prior to 60 days after You have 242 | come back into compliance. Moreover, Your grants from a particular 243 | Contributor are reinstated on an ongoing basis if such Contributor 244 | notifies You of the non-compliance by some reasonable means, this is the 245 | first time You have received notice of non-compliance with this License 246 | from such Contributor, and You become compliant prior to 30 days after 247 | Your receipt of the notice. 248 | 249 | 5.2. If You initiate litigation against any entity by asserting a patent 250 | infringement claim (excluding declaratory judgment actions, 251 | counter-claims, and cross-claims) alleging that a Contributor Version 252 | directly or indirectly infringes any patent, then the rights granted to 253 | You by any and all Contributors for the Covered Software under Section 254 | 2.1 of this License shall terminate. 255 | 256 | 5.3.

Distribution of a Larger Work 187 | 188 | You may create and distribute a Larger Work under terms of Your choice, 189 | provided that You also comply with the requirements of this License for 190 | the Covered Software. If the Larger Work is a combination of Covered 191 | Software with a work governed by one or more Secondary Licenses, and the 192 | Covered Software is not Incompatible With Secondary Licenses, this 193 | License permits You to additionally distribute such Covered Software 194 | under the terms of such Secondary License(s), so that the recipient of 195 | the Larger Work may, at their option, further distribute the Covered 196 | Software under the terms of either this License or such Secondary 197 | License(s). 198 | 199 | 3.4. Notices 200 | 201 | You may not remove or alter the substance of any license notices 202 | (including copyright notices, patent notices, disclaimers of warranty, 203 | or limitations of liability) contained within the Source Code Form of 204 | the Covered Software, except that You may alter any license notices to 205 | the extent required to remedy known factual inaccuracies. 206 | 207 | 3.5.

Termination 234 | -------------- 235 | 236 | 5.1. The rights granted under this License will terminate automatically 237 | if You fail to comply with any of its terms.

Moreover, Your grants from a particular 244 | Contributor are reinstated on an ongoing basis if such Contributor 245 | notifies You of the non-compliance by some reasonable means, this is the 246 | first time You have received notice of non-compliance with this License 247 | from such Contributor, and You become compliant prior to 30 days after 248 | Your receipt of the notice. 249 | 250 | 5.2. If You initiate litigation against any entity by asserting a patent 251 | infringement claim (excluding declaratory judgment actions, 252 | counter-claims, and cross-claims) alleging that a Contributor Version 253 | directly or indirectly infringes any patent, then the rights granted to 254 | You by any and all Contributors for the Covered Software under Section 255 | 2.1 of this License shall terminate. 256 | 257 | 5.3.

Distribution of Executable Form 172 | 173 | If You distribute Covered Software in Executable Form then: 174 | 175 | (a) such Covered Software must also be made available in Source Code 176 | Form, as described in Section 3.1, and You must inform recipients of 177 | the Executable Form how they can obtain a copy of such Source Code 178 | Form by reasonable means in a timely manner, at a charge no more 179 | than the cost of distribution to the recipient; and 180 | 181 | (b) You may distribute such Executable Form under the terms of this 182 | License, or sublicense it under different terms, provided that the 183 | license for the Executable Form does not attempt to limit or alter 184 | the recipients' rights in the Source Code Form under this License. 185 | 186 | 3.3. Distribution of a Larger Work 187 | 188 | You may create and distribute a Larger Work under terms of Your choice, 189 | provided that You also comply with the requirements of this License for 190 | the Covered Software. If the Larger Work is a combination of Covered 191 | Software with a work governed by one or more Secondary Licenses, and the 192 | Covered Software is not Incompatible With Secondary Licenses, this 193 | License permits You to additionally distribute such Covered Software 194 | under the terms of such Secondary License(s), so that the recipient of 195 | the Larger Work may, at their option, further distribute the Covered 196 | Software under the terms of either this License or such Secondary 197 | License(s). 198 | 199 | 3.4. Notices 200 | 201 | You may not remove or alter the substance of any license notices 202 | (including copyright notices, patent notices, disclaimers of warranty, 203 | or limitations of liability) contained within the Source Code Form of 204 | the Covered Software, except that You may alter any license notices to 205 | the extent required to remedy known factual inaccuracies. 206 | 207 | 3.5. Application of Additional Terms 208 | 209 | You may choose to offer, and to charge a fee for, warranty, support, 210 | indemnity or liability obligations to one or more recipients of Covered 211 | Software. However, You may do so only on Your own behalf, and not on 212 | behalf of any Contributor.

Such description must 228 | be placed in a text file included with all distributions of the Covered 229 | Software under this License. Except to the extent prohibited by statute 230 | or regulation, such description must be sufficiently detailed for a 231 | recipient of ordinary skill to be able to understand it. 232 | 233 | 5. Termination 234 | -------------- 235 | 236 | 5.1. The rights granted under this License will terminate automatically 237 | if You fail to comply with any of its terms. However, if You become 238 | compliant, then the rights granted under this License from a particular 239 | Contributor are reinstated (a) provisionally, unless and until such 240 | Contributor explicitly and finally terminates Your grants, and (b) on an 241 | ongoing basis, if such Contributor fails to notify You of the 242 | non-compliance by some reasonable means prior to 60 days after You have 243 | come back into compliance. Moreover, Your grants from a particular 244 | Contributor are reinstated on an ongoing basis if such Contributor 245 | notifies You of the non-compliance by some reasonable means, this is the 246 | first time You have received notice of non-compliance with this License 247 | from such Contributor, and You become compliant prior to 30 days after 248 | Your receipt of the notice. 249 | 250 | 5.2. If You initiate litigation against any entity by asserting a patent 251 | infringement claim (excluding declaratory judgment actions, 252 | counter-claims, and cross-claims) alleging that a Contributor Version 253 | directly or indirectly infringes any patent, then the rights granted to 254 | You by any and all Contributors for the Covered Software under Section 255 | 2.1 of this License shall terminate. 256 | 257 | 5.3. In the event of termination under Sections 5.1 or 5.2 above, all 258 | end user license agreements (excluding distributors and resellers) which 259 | have been validly granted by You or Your distributors under this License 260 | prior to termination shall survive termination. 261 | 262 | ************************************************************************ 263 | * * 264 | * 6.

Distribution of Source Form 162 | 163 | All distribution of Covered Software in Source Code Form, including any 164 | Modifications that You create or to which You contribute, must be under 165 | the terms of this License. You must inform recipients that the Source 166 | Code Form of the Covered Software is governed by the terms of this 167 | License, and how they can obtain a copy of this License. You may not 168 | attempt to alter or restrict the recipients' rights in the Source Code 169 | Form. 170 | 171 | 3.2. Distribution of Executable Form 172 | 173 | If You distribute Covered Software in Executable Form then: 174 | 175 | (a) such Covered Software must also be made available in Source Code 176 | Form, as described in Section 3.1, and You must inform recipients of 177 | the Executable Form how they can obtain a copy of such Source Code 178 | Form by reasonable means in a timely manner, at a charge no more 179 | than the cost of distribution to the recipient; and 180 | 181 | (b) You may distribute such Executable Form under the terms of this 182 | License, or sublicense it under different terms, provided that the 183 | license for the Executable Form does not attempt to limit or alter 184 | the recipients' rights in the Source Code Form under this License. 185 | 186 | 3.3. Distribution of a Larger Work 187 | 188 | You may create and distribute a Larger Work under terms of Your choice, 189 | provided that You also comply with the requirements of this License for 190 | the Covered Software. If the Larger Work is a combination of Covered 191 | Software with a work governed by one or more Secondary Licenses, and the 192 | Covered Software is not Incompatible With Secondary Licenses, this 193 | License permits You to additionally distribute such Covered Software 194 | under the terms of such Secondary License(s), so that the recipient of 195 | the Larger Work may, at their option, further distribute the Covered 196 | Software under the terms of either this License or such Secondary 197 | License(s). 198 | 199 | 3.4. Notices 200 | 201 | You may not remove or alter the substance of any license notices 202 | (including copyright notices, patent notices, disclaimers of warranty, 203 | or limitations of liability) contained within the Source Code Form of 204 | the Covered Software, except that You may alter any license notices to 205 | the extent required to remedy known factual inaccuracies. 206 | 207 | 3.5. Application of Additional Terms 208 | 209 | You may choose to offer, and to charge a fee for, warranty, support, 210 | indemnity or liability obligations to one or more recipients of Covered 211 | Software. However, You may do so only on Your own behalf, and not on 212 | behalf of any Contributor. You must make it absolutely clear that any 213 | such warranty, support, indemnity, or liability obligation is offered by 214 | You alone, and You hereby agree to indemnify every Contributor for any 215 | liability incurred by such Contributor as a result of warranty, support, 216 | indemnity or liability terms You offer. You may include additional 217 | disclaimers of warranty and limitations of liability specific to any 218 | jurisdiction. 219 | 220 | 4. Inability to Comply Due to Statute or Regulation 221 | --------------------------------------------------- 222 | 223 | If it is impossible for You to comply with any of the terms of this 224 | License with respect to some or all of the Covered Software due to 225 | statute, judicial order, or regulation then You must: (a) comply with 226 | the terms of this License to the maximum extent possible; and (b) 227 | describe the limitations and the code they affect.

Termination 234 | -------------- 235 | 236 | 5.1. The rights granted under this License will terminate automatically 237 | if You fail to comply with any of its terms. However, if You become 238 | compliant, then the rights granted under this License from a particular 239 | Contributor are reinstated (a) provisionally, unless and until such 240 | Contributor explicitly and finally terminates Your grants, and (b) on an 241 | ongoing basis, if such Contributor fails to notify You of the 242 | non-compliance by some reasonable means prior to 60 days after You have 243 | come back into compliance. Moreover, Your grants from a particular 244 | Contributor are reinstated on an ongoing basis if such Contributor 245 | notifies You of the non-compliance by some reasonable means, this is the 246 | first time You have received notice of non-compliance with this License 247 | from such Contributor, and You become compliant prior to 30 days after 248 | Your receipt of the notice. 249 | 250 | 5.2. If You initiate litigation against any entity by asserting a patent 251 | infringement claim (excluding declaratory judgment actions, 252 | counter-claims, and cross-claims) alleging that a Contributor Version 253 | directly or indirectly infringes any patent, then the rights granted to 254 | You by any and all Contributors for the Covered Software under Section 255 | 2.1 of this License shall terminate. 256 | 257 | 5.3. In the event of termination under Sections 5.1 or 5.2 above, all 258 | end user license agreements (excluding distributors and resellers) which 259 | have been validly granted by You or Your distributors under this License 260 | prior to termination shall survive termination. 261 | 262 | ************************************************************************ 263 | * * 264 | * 6.
