                     The Artistic License, Version 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.
