  license:

  a. under intellectual property rights (other than patent or trademark)
     Licensable by such Contributor to use, reproduce, make available, modify,

  The licenses granted in Section 2.1 with respect to any Contribution become
  effective for each Contribution on the date the Contributor first distributes
  such Contribution.

2.3. Limitations on Grant Scope
  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.
