ADAPTIVE PUBLIC LICENSE Version 1.0 

THE LICENSED WORK IS PROVIDED UNDER THE TERMS OF THIS ADAPTIVE PUBLIC
LICENSE ("LICENSE"). ANY USE, REPRODUCTION OR DISTRIBUTION OF THE
LICENSED WORK CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS LICENSE AND
ITS TERMS, WHETHER OR NOT SUCH RECIPIENT READS THE TERMS OF THIS
LICENSE. "LICENSED WORK" AND "RECIPIENT" ARE DEFINED BELOW.

IMPORTANT NOTE: This License is "adaptive", and the generic version or
another version of an Adaptive Public License should not be relied upon
to determine your rights and obligations under this License. You must
read the specific Adaptive Public License that you receive with the
Licensed Work, as certain terms are defined at the outset by the
Initial Contributor.

See Section 2.2 below, Exhibit A attached, and any Suppfile.txt
accompanying this License to determine the specific adaptive features
applicable to this License. For example, without limiting the
foregoing, (a) for selected choice of law and jurisdiction see Part 3
of Exhibit A; (b) for the selected definition of Third Party see Part 4
of Exhibit A; and (c) for selected patent licensing terms (if any) see
Section 2.2 below and Part 6 of Exhibit A.

    1.7. "INDEPENDENT MODULE" means a separate module of software
    and/or data that is not a derivative work of or copied from the
    Licensed Work or any portion thereof. In addition, a module does
    not qualify as an Independent Module but instead forms part of the
    Licensed Work if the module: (a) is embedded in the Licensed Work;
    (b) is included by reference in the Licensed Work other than by a
    function call or a class reference; or (c) must be included or
    contained, in whole or in part, within a file directory or
    subdirectory actually containing files making up the Licensed Work.

    the Initial Contributor in the notice required by Part 1 of Exhibit
    A.

    1.9. "INITIAL WORK" means the initial Source Code, object code (if

    1.16. "SOURCE CODE" means the source code for a computer program,
    including the source code for all modules and components of the

        Subsequent Work;

        where such changes and/or additions originate from a Subsequent
        Contributor. A Subsequent Work will "originate" from a

        such Subsequent Contributor's behalf, such as, a contractor or
        other entity that is engaged by or under the direction of the
        Subsequent Contributor). For greater certainty, a Subsequent
        Work expressly excludes and shall not capture within its
        meaning any Independent Module.

    1.19. "SUPPLEMENT FILE" means a file distributed with the Licensed
    Work having a file name "suppfile.txt".

    2.1. COPYRIGHT LICENSE FROM INITIAL AND SUBSEQUENT CONTRIBUTORS.

        (a) Subject to the terms of this License, the Initial
        Contributor hereby grants each Recipient a world-wide,
        royalty-free, non-exclusive copyright license to:

            (i) reproduce, prepare derivative works of, publicly
            display, publicly perform, distribute and sublicense the
            Initial Work; and

            (ii) reproduce, publicly display, publicly perform,
            distribute, and sublicense any derivative works (if any)
            prepared by Recipient;

        in Source Code and Executable form, either with other
        Modifications, on an unmodified basis, or as part of a Larger
        Work.

        (b) Subject to the terms of this License, each Subsequent
        Contributor hereby grants each Recipient a world-wide,
        royalty-free, non-exclusive copyright license to:

            (i) reproduce, prepare derivative works of, publicly
            display, publicly perform, distribute and sublicense the
            Subsequent Work of such Subsequent Contributor; and

            (ii) reproduce, publicly display, publicly perform,
            distribute, and sublicense any derivative works (if any)
            prepared by Recipient;

        in Source Code and Executable form, either with other
        Modifications, on an unmodified basis, or as part of a Larger
        Work.

    2.2. PATENT LICENSE FROM INITIAL AND SUBSEQUENT CONTRIBUTORS.

        (a) This License does not include or grant any patent license
        whatsoever from the Initial Contributor, Subsequent
        Contributor, or any Distributor unless, at the time the Initial
        Work is first distributed or made available under this License
        (as the case may be), the Initial Contributor has selected
        pursuant to Part 6 of Exhibit A the patent terms in paragraphs
        A, B, C, D and E from Part 6 of Exhibit A. If this is not done
        then the Initial Work and any other Subsequent Work is made
        available under the License without any patent license (the
        "PATENTS-EXCLUDED LICENSE").

        (b) However, the Initial Contributor may subsequently
        distribute or make available (as the case may be) future copies
        of: (1) the Initial Work; or (2) any Licensed Work distributed
        by the Initial Contributor which includes the Initial Work (or
        any portion thereof) and/or any Modification made by the
        Initial Contributor; available under a License which includes a
        patent license (the "PATENTS-INCLUDED LICENSE") by selecting
        pursuant to Part 6 of Exhibit A the patent terms in paragraphs
        A, B, C, D and E from Part 6 of Exhibit A, when the Initial
        Contributor distributes or makes available (as the case may be)
        such future copies under this License.

        (c) If any Recipient receives or obtains one or more copies of
        the Initial Work or any other portion of the Licensed Work
        under the Patents-Included License, then all licensing of such
        copies under this License shall include the terms in paragraphs
        A, B, C, D and E from Part 6 of Exhibit A and that Recipient
        shall not be able to rely upon the Patents-Excluded License for
        any such copies. However, all Recipients that receive one or
        more copies of the Initial Work or any other portion of the
        Licensed Work under a copy of the License which includes the
        Patents-Excluded License shall have no patent license with
        respect to such copies received under the Patents-Excluded
        License and availability and distribution of such copies,
        including Modifications made by such Recipient to such copies,
        shall be under a copy of the License without any patent
        license.

        (d) Where a Recipient uses in combination or combines any copy
        of the Licensed Work (or portion thereof) licensed under a copy
        of the License having a Patents-Excluded License with any copy
        of the Licensed Work (or portion thereof) licensed under a copy
        of the License having a Patents-Included License, the
        combination (and any portion thereof) shall, from the first
        time such Recipient uses, makes available or distributes the
        combination (as the case may be), be subject to only the terms
        of the License having the Patents-Included License which shall
        include the terms in paragraphs A, B, C, D and E from Part 6 of
        Exhibit A.

    2.3. ACKNOWLEDGEMENT AND DISCLAIMER.

    Recipient understands and agrees that although Initial Contributor
    and each Subsequent Contributor grants the licenses to its
    Contributions set forth herein, no representation, warranty,
    guarantee or assurance is provided by any Initial Contributor,
    Subsequent Contributor, or Distributor that the Licensed Work does
    not infringe the patent or other intellectual property rights of
    any other entity. Initial Contributor, Subsequent Contributor, and
    each Distributor disclaims any liability to Recipient for claims
    brought by any other entity based on infringement of intellectual
    property rights or otherwise, in relation to the Licensed Works. As
    a condition to exercising the rights and licenses granted
    hereunder, each Recipient hereby assumes sole responsibility to
    secure any other intellectual property rights needed, if any. For
    example, without limiting the foregoing disclaimers, if a third
    party patent license is required to allow Recipient to distribute
    the Licensed Work, it is Recipient's responsibility to acquire that
    license before distributing the Licensed Work.

    2.4. RESERVATION.

    Nothing in this License shall be deemed to grant any rights to
