+1. Definitions
+
+  1.1. “Contributor” means each individual or legal entity that
+  creates, contributes to the creation of, or owns Covered Software.

+  1.3. “Contribution” means Covered Software of a particular
+  Contributor.
+
+  1.4. “Covered Software” means Source Code Form to which the initial
+  Contributor has attached the notice in Exhibit A, the Executable

+  Form, in each case including portions thereof.
+
+  1.5. “Incompatible With Secondary Licenses” means
+
+  that the initial Contributor has attached the notice described in
+  Exhibit B to the Covered Software; or
+

+  version 1.1 or earlier of the License, but not also under the terms
+  of a Secondary License.

+  Code Form.

+
+
+2. License Grants and Conditions
+
+  2.1. Grants Each Contributor hereby grants You a world-wide,
+  royalty-free, non-exclusive license:
+
+  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 on an unmodified basis, with Modifications, or
+  as part of a Larger Work; and
+
+  under Patent Claims of such Contributor to make, use, sell, offer
+  for sale, have made, import, and otherwise transfer either its
+  Contributions or its Contributor Version.
+
+  2.2. Effective Date 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:
+
+  for any code that a Contributor has removed from Covered Software;
+  or
+
+  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
+
+  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:
+
+  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
+
+  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.
+
