Limitations on Grant Scope 113 | 114 | The licenses granted in this Section 2 are the only rights granted under 115 | this License. No additional rights or licenses will be implied from the 116 | distribution or licensing of Covered Software under this License. 117 | Notwithstanding Section 2.1(b) above, no patent license is granted by a 118 | Contributor: 119 | 120 | (a) for any code that a Contributor has removed from Covered Software; 121 | or 122 | 123 | (b) for infringements caused by: (i) Your and any other third party's 124 | modifications of Covered Software, or (ii) the combination of its 125 | Contributions with other software (except as part of its Contributor 126 | Version); or 127 | 128 | (c) under Patent Claims infringed by Covered Software in the absence of 129 | its Contributions. 130 | 131 | This License does not grant any rights in the trademarks, service marks, 132 | or logos of any Contributor (except as may be necessary to comply with 133 | the notice requirements in Section 3.4). 134 | 135 | 2.4. Subsequent Licenses 136 | 137 | No Contributor makes additional grants as a result of Your choice to 138 | distribute the Covered Software under a subsequent version of this 139 | License (see Section 10.2) or under the terms of a Secondary License (if 140 | permitted under the terms of Section 3.3). 141 | 142 | 2.5.

Conditions 155 | 156 | Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted 157 | in Section 2.1. 158 | 159 | 3. Responsibilities 160 | ------------------- 161 | 162 | 3.1. Distribution of Source Form 163 | 164 | All distribution of Covered Software in Source Code Form, including any 165 | Modifications that You create or to which You contribute, must be under 166 | the terms of this License. You must inform recipients that the Source 167 | Code Form of the Covered Software is governed by the terms of this 168 | License, and how they can obtain a copy of this License. You may not 169 | attempt to alter or restrict the recipients' rights in the Source Code 170 | Form. 171 | 172 | 3.2. Distribution of Executable Form 173 | 174 | If You distribute Covered Software in Executable Form then: 175 | 176 | (a) such Covered Software must also be made available in Source Code 177 | Form, as described in Section 3.1, and You must inform recipients of 178 | the Executable Form how they can obtain a copy of such Source Code 179 | Form by reasonable means in a timely manner, at a charge no more 180 | than the cost of distribution to the recipient; and 181 | 182 | (b) You may distribute such Executable Form under the terms of this 183 | License, or sublicense it under different terms, provided that the 184 | license for the Executable Form does not attempt to limit or alter 185 | the recipients' rights in the Source Code Form under this License. 186 | 187 | 3.3. Distribution of a Larger Work 188 | 189 | You may create and distribute a Larger Work under terms of Your choice, 190 | provided that You also comply with the requirements of this License for 191 | the Covered Software. If the Larger Work is a combination of Covered 192 | Software with a work governed by one or more Secondary Licenses, and the 193 | Covered Software is not Incompatible With Secondary Licenses, this 194 | License permits You to additionally distribute such Covered Software 195 | under the terms of such Secondary License(s), so that the recipient of 196 | the Larger Work may, at their option, further distribute the Covered 197 | Software under the terms of either this License or such Secondary 198 | License(s). 199 | 200 | 3.4. Notices 201 | 202 | You may not remove or alter the substance of any license notices 203 | (including copyright notices, patent notices, disclaimers of warranty, 204 | or limitations of liability) contained within the Source Code Form of 205 | the Covered Software, except that You may alter any license notices to 206 | the extent required to remedy known factual inaccuracies. 207 | 208 | 3.5. Application of Additional Terms 209 | 210 | You may choose to offer, and to charge a fee for, warranty, support, 211 | indemnity or liability obligations to one or more recipients of Covered 212 | Software. However, You may do so only on Your own behalf, and not on 213 | behalf of any Contributor. You must make it absolutely clear that any 214 | such warranty, support, indemnity, or liability obligation is offered by 215 | You alone, and You hereby agree to indemnify every Contributor for any 216 | liability incurred by such Contributor as a result of warranty, support, 217 | indemnity or liability terms You offer. You may include additional 218 | disclaimers of warranty and limitations of liability specific to any 219 | jurisdiction. 220 | 221 | 4. Inability to Comply Due to Statute or Regulation 222 | --------------------------------------------------- 223 | 224 | If it is impossible for You to comply with any of the terms of this 225 | License with respect to some or all of the Covered Software due to 226 | statute, judicial order, or regulation then You must: (a) comply with 227 | the terms of this License to the maximum extent possible; and (b) 228 | describe the limitations and the code they affect. Such description must 229 | be placed in a text file included with all distributions of the Covered 230 | Software under this License. Except to the extent prohibited by statute 231 | or regulation, such description must be sufficiently detailed for a 232 | recipient of ordinary skill to be able to understand it. 233 | 234 | 5. Termination 235 | -------------- 236 | 237 | 5.1. The rights granted under this License will terminate automatically 238 | if You fail to comply with any of its terms. However, if You become 239 | compliant, then the rights granted under this License from a particular 240 | Contributor are reinstated (a) provisionally, unless and until such 241 | Contributor explicitly and finally terminates Your grants, and (b) on an 242 | ongoing basis, if such Contributor fails to notify You of the 243 | non-compliance by some reasonable means prior to 60 days after You have 244 | come back into compliance. Moreover, Your grants from a particular 245 | Contributor are reinstated on an ongoing basis if such Contributor 246 | notifies You of the non-compliance by some reasonable means, this is the 247 | first time You have received notice of non-compliance with this License 248 | from such Contributor, and You become compliant prior to 30 days after 249 | Your receipt of the notice. 250 | 251 | 5.2. If You initiate litigation against any entity by asserting a patent 252 | infringement claim (excluding declaratory judgment actions, 253 | counter-claims, and cross-claims) alleging that a Contributor Version 254 | directly or indirectly infringes any patent, then the rights granted to 255 | You by any and all Contributors for the Covered Software under Section 256 | 2.1 of this License shall terminate. 257 | 258 | 5.3. In the event of termination under Sections 5.1 or 5.2 above, all 259 | end user license agreements (excluding distributors and resellers) which 260 | have been validly granted by You or Your distributors under this License 261 | prior to termination shall survive termination. 262 | 263 | ************************************************************************ 264 | * * 265 | * 6.

If any provision of this License is held to be 320 | unenforceable, such provision shall be reformed only to the extent 321 | necessary to make it enforceable.

Versions of the License 326 | --------------------------- 327 | 328 | 10.1. New Versions 329 | 330 | Mozilla Foundation is the license steward.

Each version will be given a 333 | distinguishing version number. 334 | 335 | 10.2. Effect of New Versions 336 | 337 | You may distribute the Covered Software under the terms of the version 338 | of the License under which You originally received the Covered Software, 339 | or under the terms of any subsequent version published by the license 340 | steward. 341 | 342 | 10.3. Modified Versions 343 | 344 | If you create software not governed by this License, and you want to 345 | create a new license for such software, you may create and use a 346 | modified version of this License if you rename the license and remove 347 | any references to the name of the license steward (except to note that 348 | such modified license differs from this License). 349 | 350 | 10.4.
