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. |
|||

|||
* * |
|||
* 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. |
|||
|
|||
