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.
