+This package is free software, and is being distributed under the terms

+
+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.
+

+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

+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.
