      "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,

      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as "Not a Contribution."

      "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.

    License

    THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE
    COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
    COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS
    AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.

    BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE
    TO BE BOUND BY THE TERMS OF THIS LICENSE. TO THE EXTENT THIS LICENSE MAY
    BE CONSIDERED TO BE A CONTRACT, THE LICENSOR GRANTS YOU THE RIGHTS
    CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND
    CONDITIONS.

    1. Definitions

     a. "Adaptation" means a work based upon the Work, or upon the Work and
        other pre-existing works, such as a translation, adaptation,
        derivative work, arrangement of music or other alterations of a
        literary or artistic work, or phonogram or performance and includes
        cinematographic adaptations or any other form in which the Work may be
        recast, transformed, or adapted including in any form recognizably
        derived from the original, except that a work that constitutes a
        Collection will not be considered an Adaptation for the purpose of
        this License. For the avoidance of doubt, where the Work is a musical
        work, performance or phonogram, the synchronization of the Work in
        timed-relation with a moving image ("synching") will be considered an
        Adaptation for the purpose of this License.
     b. "Collection" means a collection of literary or artistic works, such as
        encyclopedias and anthologies, or performances, phonograms or
        broadcasts, or other works or subject matter other than works listed
        in Section 1(f) below, which, by reason of the selection and
        arrangement of their contents, constitute intellectual creations, in
        which the Work is included in its entirety in unmodified form along
        with one or more other contributions, each constituting separate and
        independent works in themselves, which together are assembled into a
        collective whole. A work that constitutes a Collection will not be
        considered an Adaptation (as defined above) for the purposes of this
        License.
     c. "Distribute" means to make available to the public the original and
        copies of the Work or Adaptation, as appropriate, through sale or
        other transfer of ownership.
     d. "Licensor" means the individual, individuals, entity or entities that
        offer(s) the Work under the terms of this License.
     e. "Original Author" means, in the case of a literary or artistic work,
        the individual, individuals, entity or entities who created the Work
        or if no individual or entity can be identified, the publisher; and in
        addition (i) in the case of a performance the actors, singers,
        musicians, dancers, and other persons who act, sing, deliver, declaim,
        play in, interpret or otherwise perform literary or artistic works or
        expressions of folklore; (ii) in the case of a phonogram the producer
        being the person or legal entity who first fixes the sounds of a
        performance or other sounds; and, (iii) in the case of broadcasts, the
        organization that transmits the broadcast.
     f. "Work" means the literary and/or artistic work offered under the terms
        of this License including without limitation any production in the
        literary, scientific and artistic domain, whatever may be the mode or
        form of its expression including digital form, such as a book,
        pamphlet and other writing; a lecture, address, sermon or other work
        of the same nature; a dramatic or dramatico-musical work; a
        choreographic work or entertainment in dumb show; a musical
        composition with or without words; a cinematographic work to which are
        assimilated works expressed by a process analogous to cinematography;
        a work of drawing, painting, architecture, sculpture, engraving or
        lithography; a photographic work to which are assimilated works
        expressed by a process analogous to photography; a work of applied
        art; an illustration, map, plan, sketch or three-dimensional work
        relative to geography, topography, architecture or science; a
        performance; a broadcast; a phonogram; a compilation of data to the
        extent it is protected as a copyrightable work; or a work performed by
        a variety or circus performer to the extent it is not otherwise
        considered a literary or artistic work.
     g. "You" means an individual or entity exercising rights under this
        License who has not previously violated the terms of this License with
        respect to the Work, or who has received express permission from the
        Licensor to exercise rights under this License despite a previous
        violation.
     h. "Publicly Perform" means to perform public recitations of the Work and
        to communicate to the public those public recitations, by any means or
        process, including by wire or wireless means or public digital
        performances; to make available to the public Works in such a way that
        members of the public may access these Works from a place and at a
        place individually chosen by them; to perform the Work to the public
        by any means or process and the communication to the public of the
        performances of the Work, including by public digital performance; to
        broadcast and rebroadcast the Work by any means including signs,
        sounds or images.
     i. "Reproduce" means to make copies of the Work by any means including
        without limitation by sound or visual recordings and the right of
        fixation and reproducing fixations of the Work, including storage of a
        protected performance or phonogram in digital form or other electronic
        medium.

    2. Fair Dealing Rights. Nothing in this License is intended to reduce,
    limit, or restrict any uses free from copyright or rights arising from
    limitations or exceptions that are provided for in connection with the
    copyright protection under copyright law or other applicable laws.

    3. License Grant. Subject to the terms and conditions of this License,
    Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
    perpetual (for the duration of the applicable copyright) license to
    exercise the rights in the Work as stated below:

     a. to Reproduce the Work, to incorporate the Work into one or more
        Collections, and to Reproduce the Work as incorporated in the
        Collections;
     b. to create and Reproduce Adaptations provided that any such Adaptation,
        including any translation in any medium, takes reasonable steps to
        clearly label, demarcate or otherwise identify that changes were made
        to the original Work. For example, a translation could be marked "The
        original work was translated from English to Spanish," or a
        modification could indicate "The original work has been modified.";
     c. to Distribute and Publicly Perform the Work including as incorporated
        in Collections; and,
     d. to Distribute and Publicly Perform Adaptations.
     e. For the avoidance of doubt:

         i. Non-waivable Compulsory License Schemes. In those jurisdictions in
            which the right to collect royalties through any statutory or
            compulsory licensing scheme cannot be waived, the Licensor
            reserves the exclusive right to collect such royalties for any
            exercise by You of the rights granted under this License;
        ii. Waivable Compulsory License Schemes. In those jurisdictions in
            which the right to collect royalties through any statutory or
            compulsory licensing scheme can be waived, the Licensor waives the
            exclusive right to collect such royalties for any exercise by You
            of the rights granted under this License; and,
       iii. Voluntary License Schemes. The Licensor waives the right to
            collect royalties, whether individually or, in the event that the
            Licensor is a member of a collecting society that administers
            voluntary licensing schemes, via that society, from any exercise
            by You of the rights granted under this License.

    The above rights may be exercised in all media and formats whether now
    known or hereafter devised. The above rights include the right to make
    such modifications as are technically necessary to exercise the rights in
    other media and formats. Subject to Section 8(f), all rights not expressly
    granted by Licensor are hereby reserved.

    4. Restrictions. The license granted in Section 3 above is expressly made
    subject to and limited by the following restrictions:

     a. You may Distribute or Publicly Perform the Work only under the terms
        of this License. You must include a copy of, or the Uniform Resource
        Identifier (URI) for, this License with every copy of the Work You
        Distribute or Publicly Perform. You may not offer or impose any terms
        on the Work that restrict the terms of this License or the ability of
        the recipient of the Work to exercise the rights granted to that
        recipient under the terms of the License. You may not sublicense the
        Work. You must keep intact all notices that refer to this License and
        to the disclaimer of warranties with every copy of the Work You
        Distribute or Publicly Perform. When You Distribute or Publicly
        Perform the Work, You may not impose any effective technological
        measures on the Work that restrict the ability of a recipient of the
        Work from You to exercise the rights granted to that recipient under
        the terms of the License. This Section 4(a) applies to the Work as
        incorporated in a Collection, but this does not require the Collection
        apart from the Work itself to be made subject to the terms of this
        License. If You create a Collection, upon notice from any Licensor You
        must, to the extent practicable, remove from the Collection any credit
        as required by Section 4(b), as requested. If You create an
        Adaptation, upon notice from any Licensor You must, to the extent
        practicable, remove from the Adaptation any credit as required by
        Section 4(b), as requested.
     b. If You Distribute, or Publicly Perform the Work or any Adaptations or
        Collections, You must, unless a request has been made pursuant to
        Section 4(a), keep intact all copyright notices for the Work and
        provide, reasonable to the medium or means You are utilizing: (i) the
        name of the Original Author (or pseudonym, if applicable) if supplied,
        and/or if the Original Author and/or Licensor designate another party
        or parties (e.g., a sponsor institute, publishing entity, journal) for
        attribution ("Attribution Parties") in Licensor's copyright notice,
        terms of service or by other reasonable means, the name of such party
        or parties; (ii) the title of the Work if supplied; (iii) to the
        extent reasonably practicable, the URI, if any, that Licensor
        specifies to be associated with the Work, unless such URI does not
        refer to the copyright notice or licensing information for the Work;
        and (iv) , consistent with Section 3(b), in the case of an Adaptation,
        a credit identifying the use of the Work in the Adaptation (e.g.,
        "French translation of the Work by Original Author," or "Screenplay
        based on original Work by Original Author"). The credit required by
        this Section 4 (b) may be implemented in any reasonable manner;
        provided, however, that in the case of a Adaptation or Collection, at
        a minimum such credit will appear, if a credit for all contributing
        authors of the Adaptation or Collection appears, then as part of these
        credits and in a manner at least as prominent as the credits for the
        other contributing authors. For the avoidance of doubt, You may only
        use the credit required by this Section for the purpose of attribution
        in the manner set out above and, by exercising Your rights under this
        License, You may not implicitly or explicitly assert or imply any
        connection with, sponsorship or endorsement by the Original Author,
        Licensor and/or Attribution Parties, as appropriate, of You or Your
        use of the Work, without the separate, express prior written
        permission of the Original Author, Licensor and/or Attribution
        Parties.
     c. Except as otherwise agreed in writing by the Licensor or as may be
        otherwise permitted by applicable law, if You Reproduce, Distribute or
        Publicly Perform the Work either by itself or as part of any
        Adaptations or Collections, You must not distort, mutilate, modify or
        take other derogatory action in relation to the Work which would be
        prejudicial to the Original Author's honor or reputation. Licensor
        agrees that in those jurisdictions (e.g. Japan), in which any exercise
        of the right granted in Section 3(b) of this License (the right to
        make Adaptations) would be deemed to be a distortion, mutilation,
        modification or other derogatory action prejudicial to the Original
        Author's honor and reputation, the Licensor will waive or not assert,
        as appropriate, this Section, to the fullest extent permitted by the
        applicable national law, to enable You to reasonably exercise Your
        right under Section 3(b) of this License (right to make Adaptations)
        but not otherwise.

    5. Representations, Warranties and Disclaimer

    UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
    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, MERCHANTIBILITY,
    FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
    LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
    WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION
    OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.

    6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
    LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR
    ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES
    ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS
    BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

    7. Termination

     a. This License and the rights granted hereunder will terminate
        automatically upon any breach by You of the terms of this License.
        Individuals or entities who have received Adaptations or Collections
        from You under this License, however, will not have their licenses
        terminated provided such individuals or entities remain in full
        compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
        survive any termination of this License.
     b. Subject to the above terms and conditions, the license granted here is
        perpetual (for the duration of the applicable copyright in the Work).
        Notwithstanding the above, Licensor reserves the right to release the
        Work under different license terms or to stop distributing the Work at
        any time; provided, however that any such election will not serve to
        withdraw this License (or any other license that has been, or is
        required to be, granted under the terms of this License), and this
        License will continue in full force and effect unless terminated as
        stated above.

    8. Miscellaneous

     a. Each time You Distribute or Publicly Perform the Work or a Collection,
        the Licensor offers to the recipient a license to the Work on the same
        terms and conditions as the license granted to You under this License.
     b. Each time You Distribute or Publicly Perform an Adaptation, Licensor
        offers to the recipient a license to the original Work on the same
        terms and conditions as the license granted to You under this License.
     c. If any provision of this License is invalid or unenforceable under
        applicable law, it shall not affect the validity or enforceability of
        the remainder of the terms of this License, and without further action
        by the parties to this agreement, such provision shall be reformed to
        the minimum extent necessary to make such provision valid and
        enforceable.
     d. No term or provision of this License shall be deemed waived and no
        breach consented to unless such waiver or consent shall be in writing
        and signed by the party to be charged with such waiver or consent.
     e. This License constitutes the entire agreement between the parties with
        respect to the Work licensed here. There are no understandings,
        agreements or representations with respect to the Work not specified
        here. Licensor shall not be bound by any additional provisions that
        may appear in any communication from You. This License may not be
        modified without the mutual written agreement of the Licensor and You.
     f. The rights granted under, and the subject matter referenced, in this
        License were drafted utilizing the terminology of the Berne Convention
        for the Protection of Literary and Artistic Works (as amended on
        September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
        Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996
        and the Universal Copyright Convention (as revised on July 24, 1971).
        These rights and subject matter take effect in the relevant
        jurisdiction in which the License terms are sought to be enforced
        according to the corresponding provisions of the implementation of
        those treaty provisions in the applicable national law. If the
        standard suite of rights granted under applicable copyright law
        includes additional rights not granted under this License, such
        additional rights are deemed to be included in the License; this
        License is not intended to restrict the license of any rights under
        applicable law.
