3 Copyright (c) 2000-2006, The Perl Foundation.
4
5 Everyone is permitted to copy and distribute verbatim copies
6 of this license document, but changing it is not allowed.
7
8 Preamble
9
10 This license establishes the terms under which a given free software
11 Package may be copied, modified, distributed, and/or redistributed.
12 The intent is that the Copyright Holder maintains some artistic
13 control over the development of that Package while still keeping the
14 Package available as open source and free software.
15
16 You are always permitted to make arrangements wholly outside of this
17 license directly with the Copyright Holder of a given Package. If the
18 terms of this license do not permit the full use that you propose to
19 make of the Package, you should contact the Copyright Holder and seek
20 a different licensing arrangement.
21
22 Definitions
23
24 "Copyright Holder" means the individual(s) or organization(s)
25 named in the copyright notice for the entire Package.
26
27 "Contributor" means any party that has contributed code or other
28 material to the Package, in accordance with the Copyright Holder's
29 procedures.
30
31 "You" and "your" means any person who would like to copy,
32 distribute, or modify the Package.
33
34 "Package" means the collection of files distributed by the
35 Copyright Holder, and derivatives of that collection and/or of
36 those files. A given Package may consist of either the Standard
37 Version, or a Modified Version.
38
39 "Distribute" means providing a copy of the Package or making it
40 accessible to anyone else, or in the case of a company or
41 organization, to others outside of your company or organization.
42
43 "Distributor Fee" means any fee that you charge for Distributing
44 this Package or providing support for this Package to another
45 party. It does not mean licensing fees.
46
47 "Standard Version" refers to the Package if it has not been
48 modified, or has been modified only in ways explicitly requested
49 by the Copyright Holder.
50
51 "Modified Version" means the Package, if it has been changed, and
52 such changes were not explicitly requested by the Copyright
53 Holder.
54
55 "Original License" means this Artistic License as Distributed with
56 the Standard Version of the Package, in its current version or as
57 it may be modified by The Perl Foundation in the future.
58
59 "Source" form means the source code, documentation source, and
60 configuration files for the Package.
61
62 "Compiled" form means the compiled bytecode, object code, binary,
63 or any other form resulting from mechanical transformation or
64 translation of the Source form.
65
66
67 Permission for Use and Modification Without Distribution
68
69 (1) You are permitted to use the Standard Version and create and use
70 Modified Versions for any purpose without restriction, provided that
71 you do not Distribute the Modified Version.
72
73
74 Permissions for Redistribution of the Standard Version
75
76 (2) You may Distribute verbatim copies of the Source form of the
77 Standard Version of this Package in any medium without restriction,
78 either gratis or for a Distributor Fee, provided that you duplicate
79 all of the original copyright notices and associated disclaimers. At
80 your discretion, such verbatim copies may or may not include a
81 Compiled form of the Package.
82
83 (3) You may apply any bug fixes, portability changes, and other
84 modifications made available from the Copyright Holder. The resulting
85 Package will still be considered the Standard Version, and as such
86 will be subject to the Original License.
87
88
89 Distribution of Modified Versions of the Package as Source
90
91 (4) You may Distribute your Modified Version as Source (either gratis
92 or for a Distributor Fee, and with or without a Compiled form of the
93 Modified Version) provided that you clearly document how it differs
94 from the Standard Version, including, but not limited to, documenting
95 any non-standard features, executables, or modules, and provided that
96 you do at least ONE of the following:
97
98 (a) make the Modified Version available to the Copyright Holder
99 of the Standard Version, under the Original License, so that the
100 Copyright Holder may include your modifications in the Standard
101 Version.
102
103 (b) ensure that installation of your Modified Version does not
104 prevent the user installing or running the Standard Version. In
105 addition, the Modified Version must bear a name that is different
106 from the name of the Standard Version.
107
108 (c) allow anyone who receives a copy of the Modified Version to
109 make the Source form of the Modified Version available to others
110 under
111
112 (i) the Original License or
113
114 (ii) a license that permits the licensee to freely copy,
115 modify and redistribute the Modified Version using the same
116 licensing terms that apply to the copy that the licensee
117 received, and requires that the Source form of the Modified
118 Version, and of any works derived from it, be made freely
119 available in that license fees are prohibited but Distributor
120 Fees are allowed.
121
122
123 Distribution of Compiled Forms of the Standard Version
124 or Modified Versions without the Source
125
126 (5) You may Distribute Compiled forms of the Standard Version without
127 the Source, provided that you include complete instructions on how to
128 get the Source of the Standard Version. Such instructions must be
129 valid at the time of your distribution. If these instructions, at any
130 time while you are carrying out such distribution, become invalid, you
131 must provide new instructions on demand or cease further distribution.
132 If you provide valid instructions or cease distribution within thirty
133 days after you become aware that the instructions are invalid, then
134 you do not forfeit any of your rights under this license.
135
136 (6) You may Distribute a Modified Version in Compiled form without
137 the Source, provided that you comply with Section 4 with respect to
138 the Source of the Modified Version.
139
140
141 Aggregating or Linking the Package
142
143 (7) You may aggregate the Package (either the Standard Version or
144 Modified Version) with other packages and Distribute the resulting
145 aggregation provided that you do not charge a licensing fee for the
146 Package. Distributor Fees are permitted, and licensing fees for other
147 components in the aggregation are permitted. The terms of this license
148 apply to the use and Distribution of the Standard or Modified Versions
149 as included in the aggregation.
150
151 (8) You are permitted to link Modified and Standard Versions with
152 other works, to embed the Package in a larger work of your own, or to
153 build stand-alone binary or bytecode versions of applications that
154 include the Package, and Distribute the result without restriction,
155 provided the result does not expose a direct interface to the Package.
156
157
158 Items That are Not Considered Part of a Modified Version
159
160 (9) Works (including, but not limited to, modules and scripts) that
161 merely extend or make use of the Package, do not, by themselves, cause
162 the Package to be a Modified Version. In addition, such works are not
163 considered parts of the Package itself, and are not subject to the
164 terms of this license.
165
166
167 General Provisions
168
169 (10) Any use, modification, and distribution of the Standard or
170 Modified Versions is governed by this Artistic License. By using,
171 modifying or distributing the Package, you accept this license. Do not
172 use, modify, or distribute the Package, if you do not accept this
173 license.
174
175 (11) If your Modified Version has been derived from a Modified
176 Version made by someone other than you, you are nevertheless required
177 to ensure that your Modified Version complies with the requirements of
178 this license.
179
180 (12) This license does not grant you the right to use any trademark,
181 service mark, tradename, or logo of the Copyright Holder.
182
183 (13) This license includes the non-exclusive, worldwide,
184 free-of-charge patent license to make, have made, use, offer to sell,
185 sell, import and otherwise transfer the Package with respect to any
186 patent claims licensable by the Copyright Holder that are necessarily
187 infringed by the Package. If you institute patent litigation
188 (including a cross-claim or counterclaim) against any party alleging
189 that the Package constitutes direct or contributory patent
190 infringement, then this Artistic License to you shall terminate on the
191 date that such litigation is filed.
192
193 (14) Disclaimer of Warranty:
194 THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER AND CONTRIBUTORS "AS
195 IS" AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES. THE IMPLIED
196 WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR
197 NON-INFRINGEMENT ARE DISCLAIMED TO THE EXTENT PERMITTED BY YOUR LOCAL
198 LAW. UNLESS REQUIRED BY LAW, NO COPYRIGHT HOLDER OR CONTRIBUTOR WILL
199 BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
200 DAMAGES ARISING IN ANY WAY OUT OF THE USE OF THE PACKAGE, EVEN IF
201 ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.
Something went wrong with that request. Please try again.
