where such license applies only to those patent claims licensable

by such Contributor that are necessarily infringed by their

Contribution(s) alone or by combination of their Contribution(s)

with the Work to which such Contribution(s) was submitted. If You

institute patent litigation against any entity (including a

cross-claim or counterclaim in a lawsuit) alleging that the Work

or a Contribution incorporated within the Work constitutes direct

or contributory patent infringement, then any patent licenses

granted to You under this License for that Work shall terminate

as of the date such litigation is filed.

4. Redistribution. You may reproduce and distribute copies of the

of the following places: within a NOTICE text file distributed

as part of the Derivative Works; within the Source form or

documentation, if provided along with the Derivative Works; or,

within a display generated by the Derivative Works, if and

wherever such third-party notices normally appear. The contents

of the NOTICE file are for informational purposes only and

do not modify the License. You may add Your own attribution

notices within Derivative Works that You distribute, alongside

or as an addendum to the NOTICE text from the Work, provided

that such additional attribution notices cannot be construed

as modifying the License.

You may add Your own copyright statement to Your modifications and

may provide additional or different license terms and conditions

for use, reproduction, or distribution of Your modifications, or

for any such Derivative Works as a whole, provided Your use,

reproduction, and distribution of the Work otherwise complies with

the conditions stated in this License.

5. Submission of Contributions. Unless You explicitly state otherwise,

any Contribution intentionally submitted for inclusion in the Work

by You to the Licensor shall be under the terms and conditions of

this License, without any additional terms or conditions.

Notwithstanding the above, nothing herein shall supersede or modify

the terms of any separate license agreement you may have executed

with Licensor regarding such Contributions.

6. Trademarks. This License does not grant permission to use the trade

except as required for reasonable and customary use in describing the

origin of the Work and reproducing the content of the NOTICE file.

7. Disclaimer of Warranty. Unless required by applicable law or

agreed to in writing, Licensor provides the Work (and each

Contributor provides its Contributions) 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

whether in 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

Work (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.

9. Accepting Warranty or Additional Liability. While redistributing

the Work or Derivative Works thereof, You may choose to offer,

and charge a fee for, acceptance of support, warranty, indemnity,

or other liability obligations and/or rights consistent with this

License. However, in accepting such obligations, You may act 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 accepting any such warranty or additional liability.

CC0 1.0 Universal

Statement of Purpose

The laws of most jurisdictions throughout the world automatically confer

exclusive Copyright and Related Rights (defined below) upon the creator and

subsequent owner(s) (each and all, an "owner") of an original work of

authorship and/or a database (each, a "Work").

Certain owners wish to permanently relinquish those rights to a Work for the

purpose of contributing to a commons of creative, cultural and scientific

works ("Commons") that the public can reliably and without fear of later

claims of infringement build upon, modify, incorporate in other works, reuse

and redistribute as freely as possible in any form whatsoever and for any

purposes, including without limitation commercial purposes. These owners may

contribute to the Commons to promote the ideal of a free culture and the

further production of creative, cultural and scientific works, or to gain

reputation or greater distribution for their Work in part through the use and

efforts of others.

For these and/or other purposes and motivations, and without any expectation

of additional consideration or compensation, the person associating CC0 with a

Work (the "Affirmer"), to the extent that he or she is an owner of Copyright

and Related Rights in the Work, voluntarily elects to apply CC0 to the Work

and publicly distribute the Work under its terms, with knowledge of his or her

Copyright and Related Rights in the Work and the meaning and intended legal

effect of CC0 on those rights.

1. Copyright and Related Rights. A Work made available under CC0 may be

protected by copyright and related or neighboring rights ("Copyright and

Related Rights"). Copyright and Related Rights include, but are not limited

to, the following:

i. the right to reproduce, adapt, distribute, perform, display, communicate,

and translate a Work;

ii. moral rights retained by the original author(s) and/or performer(s);

iii. publicity and privacy rights pertaining to a person's image or likeness

depicted in a Work;

iv. rights protecting against unfair competition in regards to a Work,

subject to the limitations in paragraph 4(a), below;

v. rights protecting the extraction, dissemination, use and reuse of data in

a Work;

vi. database rights (such as those arising under Directive 96/9/EC of the

European Parliament and of the Council of 11 March 1996 on the legal

protection of databases, and under any national implementation thereof,

including any amended or successor version of such directive); and

vii. other similar, equivalent or corresponding rights throughout the world

based on applicable law or treaty, and any national implementations thereof.

2. Waiver. To the greatest extent permitted by, but not in contravention of,

applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and

unconditionally waives, abandons, and surrenders all of Affirmer's Copyright

and Related Rights and associated claims and causes of action, whether now

known or unknown (including existing as well as future claims and causes of

action), in the Work (i) in all territories worldwide, (ii) for the maximum

duration provided by applicable law or treaty (including future time

extensions), (iii) in any current or future medium and for any number of

copies, and (iv) for any purpose whatsoever, including without limitation

commercial, advertising or promotional purposes (the "Waiver"). Affirmer makes

the Waiver for the benefit of each member of the public at large and to the

detriment of Affirmer's heirs and successors, fully intending that such Waiver

shall not be subject to revocation, rescission, cancellation, termination, or

any other legal or equitable action to disrupt the quiet enjoyment of the Work

by the public as contemplated by Affirmer's express Statement of Purpose.

3. Public License Fallback. Should any part of the Waiver for any reason be

judged legally invalid or ineffective under applicable law, then the Waiver

shall be preserved to the maximum extent permitted taking into account

Affirmer's express Statement of Purpose. In addition, to the extent the Waiver

is so judged Affirmer hereby grants to each affected person a royalty-free,

non transferable, non sublicensable, non exclusive, irrevocable and

unconditional license to exercise Affirmer's Copyright and Related Rights in

the Work (i) in all territories worldwide, (ii) for the maximum duration

provided by applicable law or treaty (including future time extensions), (iii)

in any current or future medium and for any number of copies, and (iv) for any

purpose whatsoever, including without limitation commercial, advertising or

promotional purposes (the "License"). The License shall be deemed effective as

of the date CC0 was applied by Affirmer to the Work. Should any part of the

License for any reason be judged legally invalid or ineffective under

applicable law, such partial invalidity or ineffectiveness shall not

invalidate the remainder of the License, and in such case Affirmer hereby

affirms that he or she will not (i) exercise any of his or her remaining

Copyright and Related Rights in the Work or (ii) assert any associated claims

and causes of action with respect to the Work, in either case contrary to

Affirmer's express Statement of Purpose.

4. Limitations and Disclaimers.

a. No trademark or patent rights held by Affirmer are waived, abandoned,

surrendered, licensed or otherwise affected by this document.

b. Affirmer offers the Work as-is and makes no representations or warranties

of any kind concerning the Work, express, implied, statutory or otherwise,

including without limitation warranties of title, merchantability, fitness

for a particular purpose, non infringement, or the absence of latent or

other defects, accuracy, or the present or absence of errors, whether or not

discoverable, all to the greatest extent permissible under applicable law.

c. Affirmer disclaims responsibility for clearing rights of other persons

that may apply to the Work or any use thereof, including without limitation

any person's Copyright and Related Rights in the Work. Further, Affirmer

disclaims responsibility for obtaining any necessary consents, permissions

or other rights required for any use of the Work.

d. Affirmer understands and acknowledges that Creative Commons is not a

party to this document and has no duty or obligation with respect to this

CC0 or use of the Work.
