The 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.
