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>.

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.

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.

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.
|
---|

|
---|
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.

|
---|
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.
