 license:
  (a) under intellectual property rights (other than patent or trademark)
  Licensable by such Contributor to use, reproduce, make available, modify,
  display, perform, distribute, and otherwise exploit its Contributions, either

 The licenses granted in this Section 2 are the only rights granted under this
 License. No additional rights or licenses will be implied from the
 distribution or licensing of Covered Software under this License.
 Notwithstanding Section 2.1(b) above, no patent license is granted by a
 Contributor:
 .
  (a) for any code that a Contributor has removed from Covered Software;
    or
 .
  (b) for infringements caused by: (i) Your and any other third party's
  modifications of Covered Software, or (ii) the combination of its
  Contributions with other software (except as part of its Contributor
  Version); or
 .
  (c) under Patent Claims infringed by Covered Software in the absence of its
  Contributions.
 .
 This License does not grant any rights in the trademarks, service marks, or
 logos of any Contributor (except as may be necessary to comply with the notice
 requirements in Section 3.4).
 .
 2.4. Subsequent Licenses
 No Contributor makes additional grants as a result of Your choice to
 distribute the Covered Software under a subsequent version of this License
 (see Section 10.2) or under the terms of a Secondary License (if permitted
 under the terms of Section 3.3).
 .
 2.5. Representation
 Each Contributor represents that the Contributor believes its Contributions
 are its original creation(s) or it has sufficient rights to grant the rights
 to its Contributions conveyed by this License.
 .
 2.6. Fair Use
 This License is not intended to limit any rights You have under applicable
 copyright doctrines of fair use, fair dealing, or other equivalents.
 .
 2.7. Conditions
 Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
 Section 2.1.
 .
 3. Responsibilities
 3.1. 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. Distributing Source Code Form that is Incompatible With Secondary
 Licenses
 .
 If You choose to distribute Source Code Form that is Incompatible With
 Secondary Licenses under the terms of this version of the License, the notice
 described in Exhibit B of this License must be attached.
 .
