2. License Grants and Conditions
|
||||
--------------------------------
|
||||
|
||||
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
|
||||
as part of a Larger Work; and
|
||||
|
||||
(b) 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:
|
||||
|
||||
(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.

|
||||
* -------------------------- *
|
||||
* *
|
||||
* Under no circumstances and under no legal theory, whether tort *
|

* (including negligence), contract, or otherwise, shall any *

* 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 *

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.
