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>. |

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. |

50 | =item "Reasonable copying fee" is whatever you can justify on the basis |
51 | of media cost, duplication charges, time of people involved, and so on. |
52 | (You will not be required to justify it to the Copyright Holder, but |
53 | only to the computing community at large as a market that must bear the |
54 | fee.) |
2a551100 |
55 | |
cc2b665f |
56 | =item "Freely Available" means that no fee is charged for the item |
57 | itself, though there may be fees involved in handling the item. It also |
58 | means that recipients of the item may redistribute it under the same |
59 | conditions they received it. |

75 | You may apply bug fixes, portability fixes and other modifications |

145 | You may charge a reasonable copying fee for any distribution of this |
146 | Package. You may charge any fee you choose for support of this |
147 | Package. You may not charge a fee for this Package itself. However, |
148 | you may distribute this Package in aggregate with other (possibly |
149 | commercial) programs as part of a larger (possibly commercial) software |
150 | distribution provided that you do not advertise this Package as a |
151 | product of your own. You may embed this Package's interpreter within |
152 | an executable of yours (by linking); this shall be construed as a mere |
153 | form of aggregation, provided that the complete Standard Version of the |
154 | interpreter is so embedded. |

157 | |
158 | The scripts and library files supplied as input to or produced as |
159 | output from the programs of this Package do not automatically fall |
160 | under the copyright of this Package, but belong to whoever generated |
161 | them, and may be sold commercially, and may be aggregated with this |
162 | Package. If such scripts or library files are aggregated with this |
163 | Package via the so-called "undump" or "unexec" methods of producing a |
164 | binary executable image, then distribution of such an image shall |
165 | neither be construed as a distribution of this Package nor shall it |
166 | fall under the restrictions of Paragraphs 3 and 4, provided that you do |
167 | not represent such an executable image as a Standard Version of this |
168 | Package. |

172 | C subroutines (or comparably compiled subroutines in other |
173 | languages) supplied by you and linked into this Package in order to |
174 | emulate subroutines and variables of the language defined by this |
175 | Package shall not be considered part of this Package, but are the |
176 | equivalent of input as in Paragraph 6, provided these subroutines do |
177 | not change the language in any way that would cause it to fail the |
178 | regression tests for the language. |

2a551100 |
181 | |
182 | Aggregation of this Package with a commercial distribution is always |
183 | permitted provided that the use of this Package is embedded; that is, |
184 | when no overt attempt is made to make this Package's interfaces visible |
185 | to the end user of the commercial distribution. Such use shall not be |
186 | construed as a distribution of this Package. |
