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.

END
