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.

    If it is not possible or desirable to put the notice in a particular file,
    then You may include the notice in a location (such as a LICENSE file in a
    relevant directory) where a recipient would be likely to look for such a
    notice.

    You may add additional accurate notices of copyright ownership.
