Artistic License 2.0
Copyright (c) 2000-2006, The Perl Foundation.


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.

the copyright notice for the entire Package.

"You" and "your" means any person who would like to copy, distribute,

given Package may consist of either the Standard Version, or a

"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

be modified by The Perl Foundation in the future.

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

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

Modified Versions is governed by this Artistic License. By using,
