|
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.

78 either gratis or for a Distributor Fee, provided that you duplicate

|
|
|
97
|
|
|
98 (a) make the Modified Version available to the Copyright Holder
|
|

|
|
|
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.
|
|
|

|
|
|
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.

|
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.
|
|
|

|
