Distribution of Source Form + +All distribution of Covered Software in Source Code Form, including any Modifications +that You create or to which You contribute, must be under the terms of this +License. You must inform recipients that the Source Code Form of the Covered +Software is governed by the terms of this License, and how they can obtain +a copy of this License. You may not attempt to alter or restrict the recipients' +rights in the Source Code Form. + + 3.2. Distribution of Executable Form + + If You distribute Covered Software in Executable Form then: + +(a) such Covered Software must also be made available in Source Code Form, +as described in Section 3.1, and You must inform recipients of the Executable +Form how they can obtain a copy of such Source Code Form by reasonable means +in a timely manner, at a charge no more than the cost of distribution to the +recipient; and + +(b) You may distribute such Executable Form under the terms of this License, +or sublicense it under different terms, provided that the license for the +Executable Form does not attempt to limit or alter the recipients' rights +in the Source Code Form under this License. + + 3.3. Distribution of a Larger Work + +You may create and distribute a Larger Work under terms of Your choice, provided +that You also comply with the requirements of this License for the Covered +Software. If the Larger Work is a combination of Covered Software with a work +governed by one or more Secondary Licenses, and the Covered Software is not +Incompatible With Secondary Licenses, this License permits You to additionally +distribute such Covered Software under the terms of such Secondary License(s), +so that the recipient of the Larger Work may, at their option, further distribute +the Covered Software under the terms of either this License or such Secondary +License(s). + + 3.4. Notices + +You may not remove or alter the substance of any license notices (including +copyright notices, patent notices, disclaimers of warranty, or limitations +of liability) contained within the Source Code Form of the Covered Software, +except that You may alter any license notices to the extent required to remedy +known factual inaccuracies. + + 3.5. Application of Additional Terms + +You may choose to offer, and to charge a fee for, warranty, support, indemnity +or liability obligations to one or more recipients of Covered Software. However, +You may do so only on Your own behalf, and not on behalf of any Contributor. +You must make it absolutely clear that any such warranty, support, indemnity, +or liability obligation is offered by You alone, and You hereby agree to indemnify +every Contributor for any liability incurred by such Contributor as a result +of warranty, support, indemnity or liability terms You offer. You may include +additional disclaimers of warranty and limitations of liability specific to +any jurisdiction. + + 4. Inability to Comply Due to Statute or Regulation + +If it is impossible for You to comply with any of the terms of this License +with respect to some or all of the Covered Software due to statute, judicial +order, or regulation then You must: (a) comply with the terms of this License +to the maximum extent possible; and (b) describe the limitations and the code +they affect.

The rights granted under this License will terminate automatically if +You fail to comply with any of its terms. However, if You become compliant, +then the rights granted under this License from a particular Contributor are +reinstated (a) provisionally, unless and until such Contributor explicitly +and finally terminates Your grants, and (b) on an ongoing basis, if such Contributor +fails to notify You of the non-compliance by some reasonable means prior to +60 days after You have come back into compliance. Moreover, Your grants from +a particular Contributor are reinstated on an ongoing basis if such Contributor +notifies You of the non-compliance by some reasonable means, this is the first +time You have received notice of non-compliance with this License from such +Contributor, and You become compliant prior to 30 days after Your receipt +of the notice. + +5.2. If You initiate litigation against any entity by asserting a patent infringement +claim (excluding declaratory judgment actions, counter-claims, and cross-claims) +alleging that a Contributor Version directly or indirectly infringes any patent, +then the rights granted to You by any and all Contributors for the Covered +Software under Section 2.1 of this License shall terminate. + +5.3. In the event of termination under Sections 5.1 or 5.2 above, all end +user license agreements (excluding distributors and resellers) which have +been validly granted by You or Your distributors under this License prior +to termination shall survive termination. + + 6.

Should +any Covered Software prove defective in any respect, You (not any Contributor) +assume the cost of any necessary servicing, repair, or correction. This disclaimer +of warranty constitutes an essential part of this License. No use of any Covered +Software is authorized under this License except under this disclaimer. + + 7. Limitation of Liability + +Under no circumstances and under no legal theory, whether tort (including +negligence), contract, or otherwise, shall any Contributor, or anyone who +distributes Covered Software as permitted above, be liable to You for any +direct, indirect, special, incidental, or consequential damages of any character +including, without limitation, damages for lost profits, loss of goodwill, +work stoppage, computer failure or malfunction, or any and all other commercial +damages or losses, even if such party shall have been informed of the possibility +of such damages. This limitation of liability shall not apply to liability +for death or personal injury resulting from such party's negligence to the +extent applicable law prohibits such limitation. Some jurisdictions do not +allow the exclusion or limitation of incidental or consequential damages, +so this exclusion and limitation may not apply to You. + + 8. Litigation + +Any litigation relating to this License may be brought only in the courts +of a jurisdiction where the defendant maintains its principal place of business +and such litigation shall be governed by laws of that jurisdiction, without +reference to its conflict-of-law provisions. Nothing in this Section shall +prevent a party's ability to bring cross-claims or counter-claims. + + 9. Miscellaneous + +This License represents the complete agreement concerning the subject matter +hereof. If any provision of this License is held to be unenforceable, such +provision shall be reformed only to the extent necessary to make it enforceable. +Any law or regulation which provides that the language of a contract shall +be construed against the drafter shall not be used to construe this License +against a Contributor. + + 10. Versions of the License + + 10.1. New Versions + +Mozilla Foundation is the license steward. Except as provided in Section 10.3, +no one other than the license steward has the right to modify or publish new +versions of this License. Each version will be given a distinguishing version +number. + + 10.2. Effect of New Versions + +You may distribute the Covered Software under the terms of the version of +the License under which You originally received the Covered Software, or under +the terms of any subsequent version published by the license steward. + + 10.3. Modified Versions + +If you create software not governed by this License, and you want to create +a new license for such software, you may create and use a modified version +of this License if you rename the license and remove any references to the +name of the license steward (except to note that such modified license differs +from this License). + +10.4.

Disclaimer of Warranty + +Covered Software is provided under this License on an "as is" basis, without +warranty of any kind, either expressed, implied, or statutory, including, +without limitation, warranties that the Covered Software is free of defects, +merchantable, fit for a particular purpose or non-infringing. The entire risk +as to the quality and performance of the Covered Software is with You. Should +any Covered Software prove defective in any respect, You (not any Contributor) +assume the cost of any necessary servicing, repair, or correction. This disclaimer +of warranty constitutes an essential part of this License. No use of any Covered +Software is authorized under this License except under this disclaimer. + + 7. Limitation of Liability + +Under no circumstances and under no legal theory, whether tort (including +negligence), contract, or otherwise, shall any Contributor, or anyone who +distributes Covered Software as permitted above, be liable to You for any +direct, indirect, special, incidental, or consequential damages of any character +including, without limitation, damages for lost profits, loss of goodwill, +work stoppage, computer failure or malfunction, or any and all other commercial +damages or losses, even if such party shall have been informed of the possibility +of such damages. This limitation of liability shall not apply to liability +for death or personal injury resulting from such party's negligence to the +extent applicable law prohibits such limitation. Some jurisdictions do not +allow the exclusion or limitation of incidental or consequential damages, +so this exclusion and limitation may not apply to You. + + 8. Litigation + +Any litigation relating to this License may be brought only in the courts +of a jurisdiction where the defendant maintains its principal place of business +and such litigation shall be governed by laws of that jurisdiction, without +reference to its conflict-of-law provisions. Nothing in this Section shall +prevent a party's ability to bring cross-claims or counter-claims. + + 9. Miscellaneous + +This License represents the complete agreement concerning the subject matter +hereof. If any provision of this License is held to be unenforceable, such +provision shall be reformed only to the extent necessary to make it enforceable. +Any law or regulation which provides that the language of a contract shall +be construed against the drafter shall not be used to construe this License +against a Contributor. + + 10. Versions of the License + + 10.1. New Versions + +Mozilla Foundation is the license steward. Except as provided in Section 10.3, +no one other than the license steward has the right to modify or publish new +versions of this License. Each version will be given a distinguishing version +number. + + 10.2. Effect of New Versions + +You may distribute the Covered Software under the terms of the version of +the License under which You originally received the Covered Software, or under +the terms of any subsequent version published by the license steward. + + 10.3. Modified Versions + +If you create software not governed by this License, and you want to create +a new license for such software, you may create and use a modified version +of this License if you rename the license and remove any references to the +name of the license steward (except to note that such modified license differs +from this License). + +10.4.
