-Creative Commons Corporation ("Creative Commons") is not a law firm and
-does not provide legal services or legal advice. Distribution of
-Creative Commons public licenses does not create a lawyer-client or

-Using Creative Commons Public Licenses
-
-Creative Commons public licenses provide a standard set of terms and
-conditions that creators and other rights holders may use to share
-original works of authorship and other material subject to copyright
-and certain other rights specified in the public license below. The
-following considerations are for informational purposes only, are not
-exhaustive, and do not form part of our licenses.
-
- Considerations for licensors: Our public licenses are
- intended for use by those authorized to give the public
- permission to use material in ways otherwise restricted by
- copyright and certain other rights. Our licenses are
- irrevocable. Licensors should read and understand the terms
- and conditions of the license they choose before applying it.
- Licensors should also secure all rights necessary before
- applying our licenses so that the public can reuse the
- material as expected. Licensors should clearly mark any
- material not subject to the license. This includes other CC-
- licensed material, or material used under an exception or
- limitation to copyright. More considerations for licensors:
- wiki.creativecommons.org/Considerations_for_licensors
-
- Considerations for the public: By using one of our public
- licenses, a licensor grants the public permission to use the
- licensed material under specified terms and conditions. If
- the licensor's permission is not necessary for any reason--for
- example, because of any applicable exception or limitation to
- copyright--then that use is not regulated by the license. Our
- licenses grant only permissions under copyright and certain
- other rights that a licensor has authority to grant. Use of
- the licensed material may still be restricted for other
- reasons, including because others have copyright or other
- rights in the material. A licensor may make special requests,
- such as asking that all changes be marked or described.
- Although not required by our licenses, you are encouraged to
- respect those requests where reasonable. More_considerations

- Rights that is derived from or based upon the Licensed Material

- Treaty adopted on December 20, 1996, and/or similar international

-
- 1. Moral rights, such as the right of integrity, are not

- the extent possible, the Licensor waives and/or agrees not to
- assert any such rights held by the Licensor to the limited
- extent necessary to allow You to exercise the Licensed
- Rights, but not otherwise.
-
- 2. Patent and trademark rights are not licensed under this
- Public License.
-
- 3. To the extent possible, the Licensor waives any right to
- collect royalties from You for the exercise of the Licensed
- Rights, whether directly or through a collecting society

- reserves any right to collect such royalties.

-
- 3. If requested by the Licensor, You must remove any of the
- information required by Section 3(a)(1)(A) to the extent

- INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
- COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR

- possible, most closely approximates an absolute disclaimer and
- waiver of all liability.
-
-
-Section 6 -- Term and Termination.
-
- a. This Public License applies for the term of the Copyright and
