    Creative Commons Legal Code

    CC0 1.0 Universal

        CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
        LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
        ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
        INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
        REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
        PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
        THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
        HEREUNDER.

    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.

          source, and configuration files.

          "Object" form shall mean any form resulting from mechanical
          transformation or translation of a Source form, including but
          not limited to compiled object code, generated documentation,
          and conversions to other media types.

          "Work" shall mean the work of authorship, whether in Source or
          Object form, made available under the License, as indicated by a
          copyright notice that is included in or attached to the work
          (an example is provided in the Appendix below).

          "Derivative Works" shall mean any work, whether in Source or Object
          form, that is based on (or derived from) the Work and for which the
          editorial revisions, annotations, elaborations, or other modifications
          represent, as a whole, an original work of authorship. For the purposes
          of this License, Derivative Works shall not include works that remain
          separable from, or merely link (or bind by name) to the interfaces of,
          the Work and Derivative Works thereof.

          "Contribution" shall mean any work of authorship, including
          the original version of the Work and any modifications or additions
          to that Work or Derivative Works thereof, that is intentionally
          submitted to Licensor for inclusion in the Work by the copyright owner
          or by an individual or Legal Entity authorized to submit on behalf of
          the copyright owner. For the purposes of this definition, "submitted"
          means any form of electronic, verbal, or written communication sent
          to the Licensor or its representatives, including but not limited to
          communication on electronic mailing lists, source code control systems,
          and issue tracking systems that are managed by, or on behalf of, the
          Licensor for the purpose of discussing and improving the Work, but

          "Contributor" shall mean Licensor and any individual or Legal Entity
          on behalf of whom a Contribution has been received by Licensor and
          subsequently incorporated within the Work.

       2. Grant of Copyright License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          copyright license to reproduce, prepare Derivative Works of,
          publicly display, publicly perform, sublicense, and distribute the
          Work and such Derivative Works in Source or Object form.

       3. Grant of Patent License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          (except as stated in this section) patent license to make, have made,
          use, offer to sell, sell, import, and otherwise transfer the Work,
          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
          Work or Derivative Works thereof in any medium, with or without
          modifications, and in Source or Object form, provided that You
          meet the following conditions:

          (a) You must give any other recipients of the Work or
              Derivative Works a copy of this License; and

          (b) You must cause any modified files to carry prominent notices
              stating that You changed the files; and

          (c) You must retain, in the Source form of any Derivative Works
              that You distribute, all copyright, patent, trademark, and
              attribution notices from the Source form of the Work,
              excluding those notices that do not pertain to any part of
              the Derivative Works; and

          (d) If the Work includes a "NOTICE" text file as part of its
              distribution, then any Derivative Works that You distribute must
              include a readable copy of the attribution notices contained
              within such NOTICE file, excluding those notices that do not
              pertain to any part of the Derivative Works, in at least one
              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
          names, trademarks, service marks, or product names of the Licensor,
          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
          appropriateness of using or redistributing the Work and assume any
          risks associated with Your exercise of permissions under this License.

       8. Limitation of Liability. In no event and under no legal theory,
          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.

       END OF TERMS AND CONDITIONS

    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

    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.
