|
* 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. *
|
|
* *
|
|
* The End *
