     #
     # Each User may also freely distribute the Program, whether in its
     # original form or modified, to any third party or parties, PROVIDED
     # that the provisions of Section 3 ("NO WARRANTY") will ALWAYS appear
     # on, or be attached to, the Program, which is distributed substantially

     #
     # NO WARRANTY
     #
     # The program was produced on an experimental basis in the course of the
     # research and development conducted during the project and is provided
     # to users as so produced on an experimental basis.  Accordingly, the
     # program is provided without any warranty whatsoever, whether express,
     # implied, statutory or otherwise.  The term "warranty" used herein
     # includes, but is not limited to, any warranty of the quality,
     # performance, merchantability and fitness for a particular purpose of
     # the program and the nonexistence of any infringement or violation of
     # any right of any third party.
     #
     # Each user of the program will agree and understand, and be deemed to
     # have agreed and understood, that there is no warranty whatsoever for
     # the program and, accordingly, the entire risk arising from or
     # otherwise connected with the program is assumed by the user.
     #
     # Therefore, neither ICOT, the copyright holder, or any other
     # organization that participated in or was otherwise related to the

     # regardless of whether they have been advised of, or otherwise had
     # knowledge of, the possibility of such damages at any time during the
     # project or thereafter.  Each user will be deemed to have agreed to the
     # foregoing by his or her commencement of use of the program.  The term
     # "use" as used herein includes, but is not limited to, the use,
     # modification, copying and distribution of the program and the
     # production of secondary products from the program.
     #

    5. Time Zone Database
    ICU uses the public domain data and code derived from
    Time Zone Database for its time zone support. The ownership of the TZ database is explained
    in BCP 175: Procedure for Maintaining the Time Zone
    Database section 7.

    7.  Database Ownership

       The TZ database itself is not an IETF Contribution or an IETF
       document.  Rather it is a pre-existing and regularly updated work
       that is in the public domain, and is intended to remain in the public
       domain.  Therefore, BCPs 78 [RFC5378] and 79 [RFC3979] do not apply
       to the TZ Database or contributions that individuals make to it.
       Should any claims be made and substantiated against the TZ Database,
       the organization that is providing the IANA Considerations defined in
       this RFC, under the memorandum of understanding with the IETF,
       currently ICANN, may act in accordance with all competent court
       orders.  No ownership claims will be made by ICANN or the IETF Trust
       on the database or the code.  Any person making a contribution to the
       database or code waives all rights to future claims in that
       contribution or in the TZ Database.

    The Artistic License 2.0

    Copyright (c) 2000-2006, The Perl Foundation.

    Everyone is permitted to copy and distribute verbatim copies
    of this license document, but changing it is not allowed.

    Preamble

    This license establishes the terms under which a given free software
    Package may be copied, modified, distributed, and/or redistributed.
    The intent is that the Copyright Holder maintains some artistic
    control over the development of that Package while still keeping the
    Package available as open source and free software.

    You are always permitted to make arrangements wholly outside of this
    license directly with the Copyright Holder of a given Package.  If the
    terms of this license do not permit the full use that you propose to
    make of the Package, you should contact the Copyright Holder and seek
    a different licensing arrangement.

    Definitions

        "Copyright Holder" means the individual(s) or organization(s)
        named in the copyright notice for the entire Package.

        "Contributor" means any party that has contributed code or other
        material to the Package, in accordance with the Copyright Holder's
        procedures.

        "You" and "your" means any person who would like to copy,
        distribute, or modify the Package.

        "Package" means the collection of files distributed by the
        Copyright Holder, and derivatives of that collection and/or of
        those files. A given Package may consist of either the Standard
        Version, or a Modified Version.

        "Distribute" means providing a copy of the Package or making it
        accessible to anyone else, or in the case of a company or
        organization, to others outside of your company or organization.

        "Distributor Fee" means any fee that you charge for Distributing
        this Package or providing support for this Package to another
        party.  It does not mean licensing fees.

        "Standard Version" refers to the Package if it has not been
        modified, or has been modified only in ways explicitly requested
        by the Copyright Holder.

        "Modified Version" means the Package, if it has been changed, and
        such changes were not explicitly requested by the Copyright
        Holder.

        "Original License" means this Artistic License as Distributed with
        the Standard Version of the Package, in its current version or as
        it may be modified by The Perl Foundation in the future.

        "Source" form means the source code, documentation source, and
        configuration files for the Package.

        "Compiled" form means the compiled bytecode, object code, binary,
        or any other form resulting from mechanical transformation or
        translation of the Source form.

    Permission for Use and Modification Without Distribution

    (1)  You are permitted to use the Standard Version and create and use
    Modified Versions for any purpose without restriction, provided that
    you do not Distribute the Modified Version.

    Permissions for Redistribution of the Standard Version

    (2)  You may Distribute verbatim copies of the Source form of the
    Standard Version of this Package in any medium without restriction,
    either gratis or for a Distributor Fee, provided that you duplicate
    all of the original copyright notices and associated disclaimers.  At
    your discretion, such verbatim copies may or may not include a
    Compiled form of the Package.

    (3)  You may apply any bug fixes, portability changes, and other
    modifications made available from the Copyright Holder.  The resulting
    Package will still be considered the Standard Version, and as such
    will be subject to the Original License.

    Distribution of Modified Versions of the Package as Source

    (4)  You may Distribute your Modified Version as Source (either gratis
    or for a Distributor Fee, and with or without a Compiled form of the
    Modified Version) provided that you clearly document how it differs
    from the Standard Version, including, but not limited to, documenting
    any non-standard features, executables, or modules, and provided that
    you do at least ONE of the following:

        (a)  make the Modified Version available to the Copyright Holder
        of the Standard Version, under the Original License, so that the
        Copyright Holder may include your modifications in the Standard
        Version.

        (b)  ensure that installation of your Modified Version does not
        prevent the user installing or running the Standard Version. In
        addition, the Modified Version must bear a name that is different
        from the name of the Standard Version.

        (c)  allow anyone who receives a copy of the Modified Version to
        make the Source form of the Modified Version available to others
        under

            (i)  the Original License or

            (ii)  a license that permits the licensee to freely copy,
            modify and redistribute the Modified Version using the same
            licensing terms that apply to the copy that the licensee
            received, and requires that the Source form of the Modified
            Version, and of any works derived from it, be made freely
            available in that license fees are prohibited but Distributor
            Fees are allowed.

    Distribution of Compiled Forms of the Standard Version
    or Modified Versions without the Source

    (5)  You may Distribute Compiled forms of the Standard Version without
    the Source, provided that you include complete instructions on how to
    get the Source of the Standard Version.  Such instructions must be
    valid at the time of your distribution.  If these instructions, at any
    time while you are carrying out such distribution, become invalid, you
    must provide new instructions on demand or cease further distribution.
    If you provide valid instructions or cease distribution within thirty
    days after you become aware that the instructions are invalid, then
    you do not forfeit any of your rights under this license.

    (6)  You may Distribute a Modified Version in Compiled form without
    the Source, provided that you comply with Section 4 with respect to
    the Source of the Modified Version.

    Aggregating or Linking the Package

    (7)  You may aggregate the Package (either the Standard Version or
    Modified Version) with other packages and Distribute the resulting
    aggregation provided that you do not charge a licensing fee for the
    Package.  Distributor Fees are permitted, and licensing fees for other
    components in the aggregation are permitted. The terms of this license
    apply to the use and Distribution of the Standard or Modified Versions
    as included in the aggregation.

    (8) You are permitted to link Modified and Standard Versions with
    other works, to embed the Package in a larger work of your own, or to
    build stand-alone binary or bytecode versions of applications that
    include the Package, and Distribute the result without restriction,
    provided the result does not expose a direct interface to the Package.

    Items That are Not Considered Part of a Modified Version

    (9) Works (including, but not limited to, modules and scripts) that
    merely extend or make use of the Package, do not, by themselves, cause
    the Package to be a Modified Version.  In addition, such works are not
    considered parts of the Package itself, and are not subject to the
    terms of this license.

    General Provisions

    (10)  Any use, modification, and distribution of the Standard or
    Modified Versions is governed by this Artistic License. By using,
    modifying or distributing the Package, you accept this license. Do not
    use, modify, or distribute the Package, if you do not accept this
    license.

    (11)  If your Modified Version has been derived from a Modified
    Version made by someone other than you, you are nevertheless required
    to ensure that your Modified Version complies with the requirements of
    this license.

    (12)  This license does not grant you the right to use any trademark,
    service mark, tradename, or logo of the Copyright Holder.

    (13)  This license includes the non-exclusive, worldwide,
    free-of-charge patent license to make, have made, use, offer to sell,
    sell, import and otherwise transfer the Package with respect to any
    patent claims licensable by the Copyright Holder that are necessarily
    infringed by the Package. If you institute patent litigation
    (including a cross-claim or counterclaim) against any party alleging
    that the Package constitutes direct or contributory patent
    infringement, then this Artistic License to you shall terminate on the
    date that such litigation is filed.

    (14)  Disclaimer of Warranty:
    THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER AND CONTRIBUTORS "AS
    IS' AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES. THE IMPLIED
    WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR
    NON-INFRINGEMENT ARE DISCLAIMED TO THE EXTENT PERMITTED BY YOUR LOCAL
    LAW. UNLESS REQUIRED BY LAW, NO COPYRIGHT HOLDER OR CONTRIBUTOR WILL
    BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
    DAMAGES ARISING IN ANY WAY OUT OF THE USE OF THE PACKAGE, EVEN IF
    ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.
