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. Such description must be placed in a text file included with all + distributions of the Covered Software under this License. Except to the + extent prohibited by statute or regulation, such description must be + sufficiently detailed for a recipient of ordinary skill to be able to + understand it. + +5. Termination + +5.1. 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. 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.
