The intent is that 12the Copyright Holder maintains some artistic control over the development of 13that Package while still keeping the Package available as open source and free 14software. 15 16You are always permitted to make arrangements wholly outside of this license 17directly with the Copyright Holder of a given Package. If the terms of this 18license do not permit the full use that you propose to make of the Package, 19you should contact the Copyright Holder and seek a different licensing 20arrangement. 21 22Definitions 23 24"Copyright Holder" means the individual(s) or organization(s) named in the 25copyright notice for the entire Package. 26 27"Contributor" means any party that has contributed code or other material to 28the Package, in accordance with the Copyright Holder's procedures. 29 30"You" and "your" means any person who would like to copy, distribute, or 31modify the Package. 32 33"Package" means the collection of files distributed by the Copyright Holder, 34and derivatives of that collection and/or of those files. A given Package may 35consist of either the Standard Version, or a Modified Version. 36 37"Distribute" means providing a copy of the Package or making it accessible to 38anyone else, or in the case of a company or organization, to others outside of 39your company or organization. 40 41"Distributor Fee" means any fee that you charge for Distributing this Package 42or providing support for this Package to another party. It does not mean 43licensing fees. 44 45"Standard Version" refers to the Package if it has not been modified, or has 46been modified only in ways explicitly requested by the Copyright Holder. 47 48"Modified Version" means the Package, if it has been changed, and such changes 49were not explicitly requested by the Copyright Holder. 50 51"Original License" means this Artistic License as Distributed with the 52Standard Version of the Package, in its current version or as it may be 53modified by The Perl Foundation in the future. 54 55"Source" form means the source code, documentation source, and configuration 56files for the Package. 57 58"Compiled" form means the compiled bytecode, object code, binary, or any other 59form resulting from mechanical transformation or translation of the Source 60form. 61 62Permission for Use and Modification Without Distribution 63 64(1) You are permitted to use the Standard Version and create and use Modified 65Versions for any purpose without restriction, provided that you do not 66Distribute the Modified Version. 67 68Permissions for Redistribution of the Standard Version 69 70(2) You may Distribute verbatim copies of the Source form of the Standard 71Version of this Package in any medium without restriction, either gratis or 72for a Distributor Fee, provided that you duplicate all of the original 73copyright notices and associated disclaimers. At your discretion, such 74verbatim copies may or may not include a Compiled form of the Package. 75 76(3) You may apply any bug fixes, portability changes, and other modifications 77made available from the Copyright Holder. The resulting Package will still be 78considered the Standard Version, and as such will be subject to the Original 79License. 80 81Distribution of Modified Versions of the Package as Source 82 83(4) You may Distribute your Modified Version as Source (either gratis or for a 84Distributor Fee, and with or without a Compiled form of the Modified Version) 85provided that you clearly document how it differs from the Standard Version, 86including, but not limited to, documenting any non-standard features, 87executables, or modules, and provided that you do at least ONE of the 88following: 89 90(a) make the Modified Version available to the Copyright Holder of the 91Standard Version, under the Original License, so that the Copyright Holder may 92include your modifications in the Standard Version. 93 94(b) ensure that installation of your Modified Version does not prevent the 95user installing or running the Standard Version. In addition, the Modified 96Version must bear a name that is different from the name of the Standard 97Version. 98 99(c) allow anyone who receives a copy of the Modified Version to make the 100Source form of the Modified Version available to others under 101 102(i) the Original License or 103 104(ii) a license that permits the licensee to freely copy, modify and 105redistribute the Modified Version using the same licensing terms that apply to 106the copy that the licensee received, and requires that the Source form of the 107Modified Version, and of any works derived from it, be made freely available 108in that license fees are prohibited but Distributor Fees are allowed. 109 110Distribution of Compiled Forms of the Standard Version or Modified Versions 111without the Source 112 113(5) You may Distribute Compiled forms of the Standard Version without the 114Source, provided that you include complete instructions on how to get the 115Source of the Standard Version. Such instructions must be valid at the time of 116your distribution. If these instructions, at any time while you are carrying 117out such distribution, become invalid, you must provide new instructions on 118demand or cease further distribution. If you provide valid instructions or 119cease distribution within thirty days after you become aware that the 120instructions are invalid, then you do not forfeit any of your rights under 121this license. 122 123(6) You may Distribute a Modified Version in Compiled form without the Source, 124provided that you comply with Section 4 with respect to the Source of the 125Modified Version. 126 127Aggregating or Linking the Package 128 129(7) You may aggregate the Package (either the Standard Version or Modified 130Version) with other packages and Distribute the resulting aggregation provided 131that you do not charge a licensing fee for the Package. Distributor Fees are 132permitted, and licensing fees for other components in the aggregation are 133permitted. The terms of this license apply to the use and Distribution of the 134Standard or Modified Versions as included in the aggregation. 135 136(8) You are permitted to link Modified and Standard Versions with other works, 137to embed the Package in a larger work of your own, or to build stand-alone 138binary or bytecode versions of applications that include the Package, and 139Distribute the result without restriction, provided the result does not expose 140a direct interface to the Package. 141 142Items That are Not Considered Part of a Modified Version 143 144(9) Works (including, but not limited to, modules and scripts) that merely 145extend or make use of the Package, do not, by themselves, cause the Package to 146be a Modified Version. In addition, such works are not considered parts of the 147Package itself, and are not subject to the terms of this license. 148 149General Provisions 150 151(10) Any use, modification, and distribution of the Standard or Modified 152Versions is governed by this Artistic License. By using, modifying or 153distributing the Package, you accept this license. Do not use, modify, or 154distribute the Package, if you do not accept this license. 155 156(11) If your Modified Version has been derived from a Modified Version made by 157someone other than you, you are nevertheless required to ensure that your 158Modified Version complies with the requirements of this license. 159 160(12) This license does not grant you the right to use any trademark, service 161mark, tradename, or logo of the Copyright Holder. 162 163(13) This license includes the non-exclusive, worldwide, free-of-charge patent 164license to make, have made, use, offer to sell, sell, import and otherwise 165transfer the Package with respect to any patent claims licensable by the 166Copyright Holder that are necessarily infringed by the Package.
