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.
(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.
