2.1. Grants

Each Contributor hereby grants You a world-wide, royalty-free,
non-exclusive 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 on an unmodified basis, with Modifications, or

become effective for each Contribution on the date the Contributor first

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), 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).

3.4. Notices

You may distribute Covered Software under the terms of this License
only if You include with each copy of the Covered Software a prominent
notice stating that the Covered Software is governed by this License,
including a copyright notice and a notice that there is no warranty
(except as otherwise expressly permitted under this License), and that
recipients may contact the Contributor to obtain a copy of the Source
Code Form. You may also choose to offer, and charge a fee for, any
support, warranty, indemnity or other liability obligations and/or
rights consistent with this License. However, You may do so only on
Your own behalf, and on Your sole responsibility, not on behalf of any
other Contributor, and only if You agree to indemnify, defend, and
hold each Contributor harmless for any liability incurred by, or
claims asserted against, such Contributor by reason of your offering
any such warranty or additional liability.

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 terms of this License and fail to cure such
breach within 30 days of becoming aware of the breach. Provisions which,
by their nature, must remain in effect beyond the termination of this
License shall survive.

5.2. If You assert a patent claim against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Covered
Software or a Contribution incorporated within the Covered Software
constitutes direct or contributory patent infringement, then any patent
licenses granted to You under this License for that Covered Software
shall terminate as of the date such litigation is filed.

6. Disclaimer of Warranty
-------------------------

Unless required by applicable law or agreed to in writing, Licensor
provides the Covered Software on an "AS IS" BASIS, WITHOUT WARRANTIES
OR CONDITIONS OF ANY KIND, either express or implied, including, without
limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT,
MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are solely
responsible for determining the appropriateness of using or
redistributing the Covered Software and assume any risks associated with
Your exercise of permissions under this License.

7. Limitation of Liability
--------------------------

Under no circumstances and under no legal theory, whether tort
(including negligence), contract, or otherwise, unless required by
applicable law (such as deliberate and grossly negligent acts) or agreed
to in writing, shall any Contributor be liable to You for damages,
including any direct, indirect, special, incidental, or consequential
damages of any character arising as a result of this License or out of
the use or inability to use the Covered Software (including but not
limited to damages for loss of goodwill, work stoppage, computer failure
or malfunction, or any and all other commercial damages or losses), even
if such Contributor has been advised of the possibility of such damages.

8. Litigation
-------------

Any litigation relating to this License may be brought only in the
courts of a jurisdiction defined in a clause contained in Exhibit B,
and only under the laws of that jurisdiction excluding its
conflict-of-law provisions. The application of the United Nations
Convention on Contracts for the International Sale of Goods is expressly
excluded. Any litigation relating to this License may be brought only
in the courts of a jurisdiction defined in a clause contained in Exhibit
B, and only under the laws of that jurisdiction excluding its

excluded.

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 apply to this License. You may receive a copy of the
Exhibits to this License at https://mozilla.org/MPL/2.0/.

this License or any revised version of this License, provided that You
