It's here so that modules, 14programs, etc., that want to declare this as their distribution 15license, can link to it. 16 17It is also one of the two licenses Perl allows itself to be 18redistributed and/or modified; for the other one, the GNU General 19Public License, see the L<perlgpl>. 20 21=head1 The "Artistic License" 22 23=head2 Preamble 24 25The intent of this document is to state the conditions under which a 26Package may be copied, such that the Copyright Holder maintains some 27semblance of artistic control over the development of the package, 28while giving the users of the package the right to use and distribute 29the Package in a more-or-less customary fashion, plus the right to make 30reasonable modifications. 31 32=head2 Definitions 33 34=over 35 36=item "Package" 37 38refers to the collection of files distributed by the 39Copyright Holder, and derivatives of that collection of files created 40through textual modification. 41 42=item "Standard Version" 43 44refers to such a Package if it has not been 45modified, or has been modified in accordance with the wishes of the 46Copyright Holder as specified below. 47 48=item "Copyright Holder" 49 50is whoever is named in the copyright or 51copyrights for the package. 52 53=item "You" 54 55is you, if you're thinking about copying or distributing this Package. 56 57=item "Reasonable copying fee" 58 59is whatever you can justify on the basis 60of 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 62only to the computing community at large as a market that must bear the 63fee.) 64 65=item "Freely Available" 66 67means that no fee is charged for the item 68itself, though there may be fees involved in handling the item. It also 69means that recipients of the item may redistribute it under the same 70conditions they received it. 71 72=back 73 74=head2 Conditions 75 76=over 77 78=item 1. 79 80You may make and give away verbatim copies of the source form of the 81Standard Version of this Package without restriction, provided that you 82duplicate all of the original copyright notices and associated disclaimers. 83 84=item 2. 85 86You may apply bug fixes, portability fixes and other modifications 87derived from the Public Domain or from the Copyright Holder. A Package 88modified in such a way shall still be considered the Standard Version. 89 90=item 3. 91 92You may otherwise modify your copy of this Package in any way, provided 93that you insert a prominent notice in each changed file stating how and 94when you changed that file, and provided that you do at least ONE of the 95following: 96 97=over 98 99=item a) 100 101place your modifications in the Public Domain or otherwise make them 102Freely Available, such as by posting said modifications to Usenet or an 103equivalent medium, or placing the modifications on a major archive site 104such as uunet.uu.net, or by allowing the Copyright Holder to include 105your modifications in the Standard Version of the Package. 106 107=item b) 108 109use the modified Package only within your corporation or organization. 110 111=item c) 112 113rename any non-standard executables so the names do not conflict with 114standard executables, which must also be provided, and provide a 115separate manual page for each non-standard executable that clearly 116documents how it differs from the Standard Version. 117 118=item d) 119 120make other distribution arrangements with the Copyright Holder. 121 122=back 123 124=item 4. 125 126You may distribute the programs of this Package in object code or 127executable form, provided that you do at least ONE of the following: 128 129=over 130 131=item a) 132 133distribute a Standard Version of the executables and library files, 134together with instructions (in the manual page or equivalent) on where 135to get the Standard Version. 136 137=item b) 138 139accompany the distribution with the machine-readable source of the 140Package with your modifications. 141 142=item c) 143 144give non-standard executables non-standard names, and clearly 145document the differences in manual pages (or equivalent), together with 146instructions on where to get the Standard Version. 147 148=item d) 149 150make other distribution arrangements with the Copyright Holder. 151 152=back 153 154=item 5. 155 156You may charge a reasonable copying fee for any distribution of this 157Package. You may charge any fee you choose for support of this 158Package. You may not charge a fee for this Package itself. However, 159you may distribute this Package in aggregate with other (possibly 160commercial) programs as part of a larger (possibly commercial) software 161distribution provided that you do not advertise this Package as a 162product of your own. You may embed this Package's interpreter within 163an executable of yours (by linking); this shall be construed as a mere 164form of aggregation, provided that the complete Standard Version of the 165interpreter is so embedded. 166 167=item 6. 168 169The scripts and library files supplied as input to or produced as 170output from the programs of this Package do not automatically fall 171under the copyright of this Package, but belong to whoever generated 172them, and may be sold commercially, and may be aggregated with this 173Package. If such scripts or library files are aggregated with this 174Package via the so-called "undump" or "unexec" methods of producing a 175binary executable image, then distribution of such an image shall 176neither be construed as a distribution of this Package nor shall it 177fall under the restrictions of Paragraphs 3 and 4, provided that you do 178not represent such an executable image as a Standard Version of this 179Package. 180 181=item 7. 182 183C subroutines (or comparably compiled subroutines in other 184languages) supplied by you and linked into this Package in order to 185emulate subroutines and variables of the language defined by this 186Package shall not be considered part of this Package, but are the 187equivalent of input as in Paragraph 6, provided these subroutines do 188not change the language in any way that would cause it to fail the 189regression tests for the language. 190 191=item 8. 192 193Aggregation of this Package with a commercial distribution is always 194permitted provided that the use of this Package is embedded; that is, 195when no overt attempt is made to make this Package's interfaces visible 196to the end user of the commercial distribution. Such use shall not be 197construed as a distribution of this Package. 198 199=item 9. 200 201The name of the Copyright Holder may not be used to endorse or promote 202products derived from this software without specific prior written permission. 203 204 205=item 10. 206 207THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR 208IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED 209WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE. 210 211=back 212 213The End 214 215=cut 216 217 218
