A given Package may consist of either the Standard 38 Version, or a Modified Version. 39 40 "Distribute" means providing a copy of the Package or making it 41 accessible to anyone else, or in the case of a company or 42 organization, to others outside of your company or organization. 43 44 "Distributor Fee" means any fee that you charge for Distributing 45 this Package or providing support for this Package to another 46 party. It does not mean licensing fees. 47 48 "Standard Version" refers to the Package if it has not been 49 modified, or has been modified only in ways explicitly requested 50 by the Copyright Holder. 51 52 "Modified Version" means the Package, if it has been changed, and 53 such changes were not explicitly requested by the Copyright 54 Holder. 55 56 "Original License" means this Artistic License as Distributed with 57 the Standard Version of the Package, in its current version or as 58 it may be modified by The Perl Foundation in the future. 59 60 "Source" form means the source code, documentation source, and 61 configuration files for the Package. 62 63 "Compiled" form means the compiled bytecode, object code, binary, 64 or any other form resulting from mechanical transformation or 65 translation of the Source form. 66 67 68Permission for Use and Modification Without Distribution 69 70(1) You are permitted to use the Standard Version and create and use 71Modified Versions for any purpose without restriction, provided that 72you do not Distribute the Modified Version. 73 74 75Permissions for Redistribution of the Standard Version 76 77(2) You may Distribute verbatim copies of the Source form of the 78Standard Version of this Package in any medium without restriction, 79either gratis or for a Distributor Fee, provided that you duplicate 80all of the original copyright notices and associated disclaimers. At 81your discretion, such verbatim copies may or may not include a 82Compiled form of the Package. 83 84(3) You may apply any bug fixes, portability changes, and other 85modifications made available from the Copyright Holder. The resulting 86Package will still be considered the Standard Version, and as such 87will be subject to the Original License. 88 89 90Distribution of Modified Versions of the Package as Source 91 92(4) You may Distribute your Modified Version as Source (either gratis 93or for a Distributor Fee, and with or without a Compiled form of the 94Modified Version) provided that you clearly document how it differs 95from the Standard Version, including, but not limited to, documenting 96any non-standard features, executables, or modules, and provided that 97you do at least ONE of the following: 98 99 (a) make the Modified Version available to the Copyright Holder 100 of the Standard Version, under the Original License, so that the 101 Copyright Holder may include your modifications in the Standard 102 Version. 103 104 (b) ensure that installation of your Modified Version does not 105 prevent the user installing or running the Standard Version. In 106 addition, the Modified Version must bear a name that is different 107 from the name of the Standard Version. 108 109 (c) allow anyone who receives a copy of the Modified Version to 110 make the Source form of the Modified Version available to others 111 under 112 113 (i) the Original License or 114 115 (ii) a license that permits the licensee to freely copy, 116 modify and redistribute the Modified Version using the same 117 licensing terms that apply to the copy that the licensee 118 received, and requires that the Source form of the Modified 119 Version, and of any works derived from it, be made freely 120 available in that license fees are prohibited but Distributor 121 Fees are allowed. 122 123 124Distribution of Compiled Forms of the Standard Version 125or Modified Versions without the Source 126 127(5) You may Distribute Compiled forms of the Standard Version without 128the Source, provided that you include complete instructions on how to 129get the Source of the Standard Version. Such instructions must be 130valid at the time of your distribution. If these instructions, at any 131time while you are carrying out such distribution, become invalid, you 132must provide new instructions on demand or cease further distribution. 133If you provide valid instructions or cease distribution within thirty 134days after you become aware that the instructions are invalid, then 135you do not forfeit any of your rights under this license. 136 137(6) You may Distribute a Modified Version in Compiled form without 138the Source, provided that you comply with Section 4 with respect to 139the Source of the Modified Version. 140 141 142Aggregating or Linking the Package 143 144(7) You may aggregate the Package (either the Standard Version or 145Modified Version) with other packages and Distribute the resulting 146aggregation provided that you do not charge a licensing fee for the 147Package.
