| 11 | =head1 DESCRIPTION |
| 12 | |
| 13 | This is B<"The Artistic License">. It's here so that modules, |
| 14 | programs, etc., that want to declare this as their distribution |
| 15 | license, can link to it. |
| 16 | |
| 17 | It is also one of the two licenses Perl allows itself to be |
| 18 | redistributed and/or modified; for the other one, the GNU General |
| 19 | Public License, see the L<perlgpl>. |
| 20 | |
| 21 | =head1 The "Artistic License" |
| 22 | |
| 23 | =head2 Preamble |
| 24 | |
| 25 | The intent of this document is to state the conditions under which a |
| 26 | Package may be copied, such that the Copyright Holder maintains some |
| 27 | semblance of artistic control over the development of the package, |
| 28 | while giving the users of the package the right to use and distribute |
| 29 | the Package in a more-or-less customary fashion, plus the right to make |
| 30 | reasonable modifications. |
| 31 | |
| 32 | =head2 Definitions |
| 33 | |
| 34 | =over |
| 35 | |
| 36 | =item "Package" |
| 37 | |
| 38 | refers to the collection of files distributed by the |
| 39 | Copyright Holder, and derivatives of that collection of files created |
| 40 | through textual modification. |
| 41 | |
| 42 | =item "Standard Version" |
| 43 | |
| 44 | refers to such a Package if it has not been |
| 45 | modified, or has been modified in accordance with the wishes of the |
| 46 | Copyright Holder as specified below. |
| 47 | |
| 48 | =item "Copyright Holder" |
| 49 | |
| 50 | is whoever is named in the copyright or |
| 51 | copyrights for the package. |
| 52 | |
| 53 | =item "You" |
| 54 | |
| 55 | is you, if you're thinking about copying or distributing this Package. |
| 56 | |
| 57 | =item "Reasonable copying fee" |
| 58 | |
| 59 | is whatever you can justify on the basis |
| 60 | of media cost, duplication charges, time of people involved, and so on. |
| 61 | (You will not be required to justify it to the Copyright Holder, but |
| 62 | only to the computing community at large as a market that must bear the |
| 63 | fee.) |
| 64 | |
| 65 | =item "Freely Available" |
| 66 | |
| 67 | means that no fee is charged for the item |
| 68 | itself, though there may be fees involved in handling the item. It also |
| 69 | means that recipients of the item may redistribute it under the same |
| 70 | conditions they received it. |

| 73 | |
| 74 | =head2 Conditions |
| 75 | |
| 76 | =over |
| 77 | |
| 78 | =item 1. |
| 79 | |
| 80 | You may make and give away verbatim copies of the source form of the |
| 81 | Standard Version of this Package without restriction, provided that you |
| 82 | duplicate all of the original copyright notices and associated disclaimers. |
| 83 | |
| 84 | =item 2. |
| 85 | |
| 86 | You may apply bug fixes, portability fixes and other modifications |
| 87 | derived from the Public Domain or from the Copyright Holder. A Package |
| 88 | modified in such a way shall still be considered the Standard Version. |
| 89 | |
| 90 | =item 3. |
| 91 | |
| 92 | You may otherwise modify your copy of this Package in any way, provided |
| 93 | that you insert a prominent notice in each changed file stating how and |
| 94 | when you changed that file, and provided that you do at least ONE of the |
| 95 | following: |
| 96 | |
| 97 | =over |
| 98 | |
| 99 | =item a) |
| 100 | |
| 101 | place your modifications in the Public Domain or otherwise make them |
| 102 | Freely Available, such as by posting said modifications to Usenet or an |
| 103 | equivalent medium, or placing the modifications on a major archive site |
| 104 | such as uunet.uu.net, or by allowing the Copyright Holder to include |
| 105 | your modifications in the Standard Version of the Package. |
| 106 | |
| 107 | =item b) |
| 108 | |
| 109 | use the modified Package only within your corporation or organization. |
| 110 | |
| 111 | =item c) |
| 112 | |
| 113 | rename any non-standard executables so the names do not conflict with |
| 114 | standard executables, which must also be provided, and provide a |
| 115 | separate manual page for each non-standard executable that clearly |
| 116 | documents how it differs from the Standard Version. |
| 117 | |
| 118 | =item d) |
| 119 | |
| 120 | make other distribution arrangements with the Copyright Holder. |
| 121 | |
| 122 | =back |
| 123 | |
| 124 | =item 4. |
| 125 | |
| 126 | You may distribute the programs of this Package in object code or |
| 127 | executable form, provided that you do at least ONE of the following: |
| 128 | |
| 129 | =over |
| 130 | |
| 131 | =item a) |
| 132 | |
| 133 | distribute a Standard Version of the executables and library files, |
| 134 | together with instructions (in the manual page or equivalent) on where |
| 135 | to get the Standard Version. |
| 136 | |
| 137 | =item b) |
| 138 | |
| 139 | accompany the distribution with the machine-readable source of the |
| 140 | Package with your modifications. |
| 141 | |
| 142 | =item c) |
| 143 | |
| 144 | give non-standard executables non-standard names, and clearly |
| 145 | document the differences in manual pages (or equivalent), together with |
| 146 | instructions on where to get the Standard Version. |
| 147 | |
| 148 | =item d) |
| 149 | |
| 150 | make other distribution arrangements with the Copyright Holder. |
| 151 | |
| 152 | =back |
| 153 | |
| 154 | =item 5. |
| 155 | |
| 156 | You may charge a reasonable copying fee for any distribution of this |
| 157 | Package. You may charge any fee you choose for support of this |
| 158 | Package. You may not charge a fee for this Package itself. However, |
| 159 | you may distribute this Package in aggregate with other (possibly |
| 160 | commercial) programs as part of a larger (possibly commercial) software |
| 161 | distribution provided that you do not advertise this Package as a |
| 162 | product of your own. You may embed this Package's interpreter within |
| 163 | an executable of yours (by linking); this shall be construed as a mere |
| 164 | form of aggregation, provided that the complete Standard Version of the |
| 165 | interpreter is so embedded. |
| 166 | |
| 167 | =item 6. |
| 168 | |
| 169 | The scripts and library files supplied as input to or produced as |
| 170 | output from the programs of this Package do not automatically fall |
| 171 | under the copyright of this Package, but belong to whoever generated |
| 172 | them, and may be sold commercially, and may be aggregated with this |
| 173 | Package. If such scripts or library files are aggregated with this |
| 174 | Package via the so-called "undump" or "unexec" methods of producing a |
| 175 | binary executable image, then distribution of such an image shall |
| 176 | neither be construed as a distribution of this Package nor shall it |
| 177 | fall under the restrictions of Paragraphs 3 and 4, provided that you do |
| 178 | not represent such an executable image as a Standard Version of this |
| 179 | Package. |
| 180 | |
| 181 | =item 7. |
| 182 | |
| 183 | C subroutines (or comparably compiled subroutines in other |
| 184 | languages) supplied by you and linked into this Package in order to |
| 185 | emulate subroutines and variables of the language defined by this |
| 186 | Package shall not be considered part of this Package, but are the |
| 187 | equivalent of input as in Paragraph 6, provided these subroutines do |
| 188 | not change the language in any way that would cause it to fail the |
| 189 | regression tests for the language. |
| 190 | |
| 191 | =item 8. |
| 192 | |
| 193 | Aggregation of this Package with a commercial distribution is always |
| 194 | permitted provided that the use of this Package is embedded; that is, |
| 195 | when no overt attempt is made to make this Package's interfaces visible |
| 196 | to the end user of the commercial distribution. Such use shall not be |
| 197 | construed as a distribution of this Package. |
| 198 | |
| 199 | =item 9. |
| 200 | |
| 201 | The name of the Copyright Holder may not be used to endorse or promote |
| 202 | products derived from this software without specific prior written permission. |
