|
---|
20 | This license establishes the terms under which a given free software
|
---|
21 | Package may be copied, modified, distributed, and/or redistributed.
|
---|
22 | The intent is that the Copyright Holder maintains some artistic
|
---|
23 | control over the development of that Package while still keeping the
|
---|
24 | Package available as open source and free software.
|
---|
25 |
|
---|
26 | You are always permitted to make arrangements wholly outside of this
|
---|
27 | license directly with the Copyright Holder of a given Package. If the
|
---|
28 | terms of this license do not permit the full use that you propose to
|
---|
29 | make of the Package, you should contact the Copyright Holder and seek
|
---|
30 | a different licensing arrangement.

|
---|
78 |
|
---|
79 | (1) You are permitted to use the Standard Version and create and use

82 |

|
---|
84 | Permissions for Redistribution of the Standard Version

---|
88 | either gratis or for a Distributor Fee, provided that you duplicate

|
---|
92 |

|
---|
104 | from the Standard Version, including, but not limited to, documenting
|
---|
105 | any non-standard features, executables, or modules, and provided that
|
---|
106 | you do at least ONE of the following:
|
---|
107 |
|
---|
108 | (a) make the Modified Version available to the Copyright Holder
|
---|
109 | of the Standard Version, under the Original License, so that the
|
---|
110 | Copyright Holder may include your modifications in the Standard
|
---|
111 | Version.
|
---|
112 |
|
---|
113 | (b) ensure that installation of your Modified Version does not
|
---|
114 | prevent the user installing or running the Standard Version. In
|
---|
115 | addition, the Modified Version must bear a name that is different
|
---|
116 | from the name of the Standard Version.
|
---|
117 |
|
---|
118 | (c) allow anyone who receives a copy of the Modified Version to
|
---|
119 | make the Source form of the Modified Version available to others
|
---|
120 | under
|
---|
121 |
|
---|
122 | (i) the Original License or
|
---|
123 |
|
---|
124 | (ii) a license that permits the licensee to freely copy,
|
---|
125 | modify and redistribute the Modified Version using the same
|
---|
126 | licensing terms that apply to the copy that the licensee
|
---|
127 | received, and requires that the Source form of the Modified
|
---|
128 | Version, and of any works derived from it, be made freely
|
---|
129 | available in that license fees are prohibited but Distributor
|
---|
130 | Fees are allowed.
|
---|
131 |
|
---|
132 |
|
---|
133 | Distribution of Compiled Forms of the Standard Version
|
---|
134 | or Modified Versions without the Source
|
---|
135 |
|
---|
136 | (5) You may Distribute Compiled forms of the Standard Version without
|
---|
137 | the Source, provided that you include complete instructions on how to
|
---|
138 | get the Source of the Standard Version. Such instructions must be
|
---|
139 | valid at the time of your distribution. If these instructions, at any
|
---|
140 | time while you are carrying out such distribution, become invalid, you
|
---|
141 | must provide new instructions on demand or cease further distribution.
|
---|
142 | If you provide valid instructions or cease distribution within thirty
|
---|
143 | days after you become aware that the instructions are invalid, then
|
---|
144 | you do not forfeit any of your rights under this license.
|
---|
145 |
|
---|
146 | (6) You may Distribute a Modified Version in Compiled form without
|
---|
147 | the Source, provided that you comply with Section 4 with respect to
|
---|
148 | the Source of the Modified Version.

---|
149 |
|
---|
150 |
|
---|
151 | Aggregating or Linking the Package
|
---|
152 |
|
---|
153 | (7) You may aggregate the Package (either the Standard Version or
|
---|
154 | Modified Version) with other packages and Distribute the resulting
|
---|
155 | aggregation provided that you do not charge a licensing fee for the
|
---|
156 | Package. Distributor Fees are permitted, and licensing fees for other
|
---|
157 | components in the aggregation are permitted. The terms of this license
|
---|
158 | apply to the use and Distribution of the Standard or Modified Versions
|
---|
159 | as included in the aggregation.
|
---|
160 |
|
---|
161 | (8) You are permitted to link Modified and Standard Versions with
|
---|
162 | other works, to embed the Package in a larger work of your own, or to
|
---|
163 | build stand-alone binary or bytecode versions of applications that
|
---|
164 | include the Package, and Distribute the result without restriction,
|
---|
165 | provided the result does not expose a direct interface to the Package.
|
---|
166 |
|
---|
167 |
|
---|
168 | Items That are Not Considered Part of a Modified Version
|
---|
169 |
|
---|
170 | (9) Works (including, but not limited to, modules and scripts) that
|
---|
171 | merely extend or make use of the Package, do not, by themselves, cause
|
---|
172 | the Package to be a Modified Version. In addition, such works are not
|
---|
173 | considered parts of the Package itself, and are not subject to the
|
---|
174 | terms of this license.
|
---|
175 |
|
---|
176 |
|
---|
177 | General Provisions
|
---|
178 |
|
---|
179 | (10) Any use, modification, and distribution of the Standard or
|
---|
180 | Modified Versions is governed by this Artistic License. By using,
|
---|
181 | modifying or distributing the Package, you accept this license. Do not
|
---|
182 | use, modify, or distribute the Package, if you do not accept this
|
---|
183 | license.
|
---|
184 |
|
---|
185 | (11) If your Modified Version has been derived from a Modified
|
---|
186 | Version made by someone other than you, you are nevertheless required
|
---|
187 | to ensure that your Modified Version complies with the requirements of
|
---|
188 | this license.
|
---|
189 |
|
---|
190 | (12) This license does not grant you the right to use any trademark,
|
---|
191 | service mark, tradename, or logo of the Copyright Holder.
|
---|
192 |
|
---|
193 | (13) This license includes the non-exclusive, worldwide,
|
---|
194 | free-of-charge patent license to make, have made, use, offer to sell,
|
---|
195 | sell, import and otherwise transfer the Package with respect to any
|
---|
196 | patent claims licensable by the Copyright Holder that are necessarily
|
---|
197 | infringed by the Package. If you institute patent litigation
|
---|
198 | (including a cross-claim or counterclaim) against any party alleging
|
---|
199 | that the Package constitutes direct or contributory patent
|
---|
200 | infringement, then this Artistic License to you shall terminate on the
|
---|
201 | date that such litigation is filed.
|
---|
202 |
