1 Linden Research, Inc. ("Linden Lab") Viewer FLOSS License Exception v0.5
2
3 The Linden Lab Exception for Free/Libre and Open Source Software-only Applications Using Linden Lab Viewer Software (the "FLOSS Exception").
4
5 Exception Intent
6
7 Linden Lab is releasing the source code for certain software that enables users to view or otherwise access the Second Life virtual world environment (the "Viewer Software"), under version 2 of the GNU General Public License (the "GPL"). The creation or distribution of works based on the Program (as defined under the GPL) of the Viewer Software may require the use of certain Free/Libre and Open Source Software ("FLOSS") works that are subject to license agreements not compatible with re-licensing under the GPL. Because we want to allow the Viewer Software to be distributed with these FLOSS works, this FLOSS Exception following exception applies subject to the terms and conditions below.
8
9 Legal Terms and Conditions
10
11 As a special exception to the terms and conditions of version 2.0 of the GPL:
12
13 You are free to distribute a work based on the Program that is formed entirely from the Viewer Software (and any modifications thereof) and one or more works that are independent and separate works not derived from the Viewer Software, and are licensed under one or more of the licenses listed below in section 1 (each, a "FLOSS Work") , as long as:
14
15 1. You obey the GPL in all respects for the Viewer Software and any work based on the Program, except for the FLOSS Works, for which you must comply with B below,
16 2. all FLOSS Works,
17 1. are distributed subject to one of the FLOSS licenses listed below, and
18 2. the object code or executable form of the FLOSS Works are accompanied by the complete corresponding machine-readable source code for those FLOSS Works on the same medium and under the same FLOSS license as the corresponding object code or executable forms thereof, and
19 3. any works that are aggregated with the Viewer Software or a work based on the Program on a volume of a storage or distribution medium in accordance with the GPL, and are not licensed under the FLOSS licenses listed below, are independent and separate works in themselves which are not derivatives of either the Viewer Software, a work based on the Program or a FLOSS Work.
20
21 If the above conditions are not met, then the Viewer Software may only be copied, modified, distributed or used under the terms and conditions of the GPL or another valid licensing option from Linden Lab.

51 Terms used, but not defined, herein shall have the meaning provided in the GPL.
52
53 3. Applicability
54
55 This FLOSS Exception applies to all Viewer Software files that contain a notice placed by Linden Lab saying that the Viewer Software may be distributed under the terms of this FLOSS Exception. If you create or distribute a work which is a work based on the Program for the Viewer Software and any other work licensed under the GPL, then this FLOSS Exception is not available for that work; thus, you must remove the FLOSS Exception notice from that work and comply with the GPL in all respects, including by retaining all GPL notices. You may choose to redistribute a copy of the Viewer Software exclusively under the terms of the GPL by removing the FLOSS Exception notice from that copy of the Viewer Software, provided that the copy has never been modified by you or any third party.

58 GNU GENERAL PUBLIC LICENSE
59 Version 2, June 1991
60
61 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
62 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
63 Everyone is permitted to copy and distribute verbatim copies
64 of this license document, but changing it is not allowed.
65
66 Preamble
67
68 The licenses for most software are designed to take away your
69 freedom to share and change it. By contrast, the GNU General Public
70 License is intended to guarantee your freedom to share and change free
71 software--to make sure the software is free for all its users. This
72 General Public License applies to most of the Free Software
73 Foundation's software and to any other program whose authors commit to
74 using it. (Some other Free Software Foundation software is covered by
75 the GNU Library General Public License instead.) You can apply it to
76 your programs, too.
77
78 When we speak of free software, we are referring to freedom, not
79 price. Our General Public Licenses are designed to make sure that you
80 have the freedom to distribute copies of free software (and charge for
81 this service if you wish), that you receive source code or can get it
82 if you want it, that you can change the software or use pieces of it
83 in new free programs; and that you know you can do these things.
84
85 To protect your rights, we need to make restrictions that forbid
86 anyone to deny you these rights or to ask you to surrender the rights.
87 These restrictions translate to certain responsibilities for you if you
88 distribute copies of the software, or if you modify it.
89
90 For example, if you distribute copies of such a program, whether
91 gratis or for a fee, you must give the recipients all the rights that
92 you have. You must make sure that they, too, receive or can get the
93 source code. And you must show them these terms so they know their
94 rights.
95
96 We protect your rights with two steps: (1) copyright the software, and
97 (2) offer you this license which gives you legal permission to copy,
98 distribute and/or modify the software.
99
100 Also, for each author's protection and ours, we want to make certain
101 that everyone understands that there is no warranty for this free
102 software. If the software is modified by someone else and passed on, we
103 want its recipients to know that what they have is not the original, so
104 that any problems introduced by others will not reflect on the original
105 authors' reputations.
106
107 Finally, any free program is threatened constantly by software
108 patents. We wish to avoid the danger that redistributors of a free
109 program will individually obtain patent licenses, in effect making the
110 program proprietary. To prevent this, we have made it clear that any
111 patent must be licensed for everyone's free use or not licensed at all.
112
113 The precise terms and conditions for copying, distribution and
114 modification follow.
115
116 GNU GENERAL PUBLIC LICENSE
117 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
118
119 0. This License applies to any program or other work which contains
120 a notice placed by the copyright holder saying it may be distributed
121 under the terms of this General Public License. The "Program", below,
122 refers to any such program or work, and a "work based on the Program"
123 means either the Program or any derivative work under copyright law:
124 that is to say, a work containing the Program or a portion of it,
125 either verbatim or with modifications and/or translated into another
126 language. (Hereinafter, translation is included without limitation in
127 the term "modification".) Each licensee is addressed as "you".
128
129 Activities other than copying, distribution and modification are not
130 covered by this License; they are outside its scope. The act of
131 running the Program is not restricted, and the output from the Program
132 is covered only if its contents constitute a work based on the
133 Program (independent of having been made by running the Program).
134 Whether that is true depends on what the Program does.
135
136 1. You may copy and distribute verbatim copies of the Program's
137 source code as you receive it, in any medium, provided that you
138 conspicuously and appropriately publish on each copy an appropriate
139 copyright notice and disclaimer of warranty; keep intact all the
140 notices that refer to this License and to the absence of any warranty;
141 and give any other recipients of the Program a copy of this License
142 along with the Program.
143
144 You may charge a fee for the physical act of transferring a copy, and
145 you may at your option offer warranty protection in exchange for a fee.
146
147 2. You may modify your copy or copies of the Program or any portion
148 of it, thus forming a work based on the Program, and copy and
149 distribute such modifications or work under the terms of Section 1
150 above, provided that you also meet all of these conditions:
151
152 a) You must cause the modified files to carry prominent notices
153 stating that you changed the files and the date of any change.
154
155 b) You must cause any work that you distribute or publish, that in
156 whole or in part contains or is derived from the Program or any
157 part thereof, to be licensed as a whole at no charge to all third
158 parties under the terms of this License.
159
160 c) If the modified program normally reads commands interactively
161 when run, you must cause it, when started running for such
162 interactive use in the most ordinary way, to print or display an
163 announcement including an appropriate copyright notice and a
164 notice that there is no warranty (or else, saying that you provide
165 a warranty) and that users may redistribute the program under
166 these conditions, and telling the user how to view a copy of this
167 License. (Exception: if the Program itself is interactive but
168 does not normally print such an announcement, your work based on
169 the Program is not required to print an announcement.)
170
171 These requirements apply to the modified work as a whole. If
172 identifiable sections of that work are not derived from the Program,
173 and can be reasonably considered independent and separate works in
174 themselves, then this License, and its terms, do not apply to those
175 sections when you distribute them as separate works. But when you
176 distribute the same sections as part of a whole which is a work based
177 on the Program, the distribution of the whole must be on the terms of
178 this License, whose permissions for other licensees extend to the
179 entire whole, and thus to each and every part regardless of who wrote it.
180
181 Thus, it is not the intent of this section to claim rights or contest
182 your rights to work written entirely by you; rather, the intent is to
183 exercise the right to control the distribution of derivative or
184 collective works based on the Program.
185
186 In addition, mere aggregation of another work not based on the Program
187 with the Program (or with a work based on the Program) on a volume of
188 a storage or distribution medium does not bring the other work under
189 the scope of this License.
190
191 3. You may copy and distribute the Program (or a work based on it,
192 under Section 2) in object code or executable form under the terms of
193 Sections 1 and 2 above provided that you also do one of the following:
194
195 a) Accompany it with the complete corresponding machine-readable
196 source code, which must be distributed under the terms of Sections
197 1 and 2 above on a medium customarily used for software interchange; or,
198
199 b) Accompany it with a written offer, valid for at least three
200 years, to give any third party, for a charge no more than your
201 cost of physically performing source distribution, a complete
202 machine-readable copy of the corresponding source code, to be
203 distributed under the terms of Sections 1 and 2 above on a medium
204 customarily used for software interchange; or,
205
206 c) Accompany it with the information you received as to the offer
207 to distribute corresponding source code. (This alternative is
208 allowed only for noncommercial distribution and only if you
209 received the program in object code or executable form with such
210 an offer, in accord with Subsection b above.)
211
212 The source code for a work means the preferred form of the work for
213 making modifications to it. For an executable work, complete source
214 code means all the source code for all modules it contains, plus any
215 associated interface definition files, plus the scripts used to
216 control compilation and installation of the executable. However, as a
217 special exception, the source code distributed need not include
218 anything that is normally distributed (in either source or binary
219 form) with the major components (compiler, kernel, and so on) of the
220 operating system on which the executable runs, unless that component
221 itself accompanies the executable.
222
223 If distribution of executable or object code is made by offering
224 access to copy from a designated place, then offering equivalent
225 access to copy the source code from the same place counts as
226 distribution of the source code, even though third parties are not
227 compelled to copy the source along with the object code.
228
229 4. You may not copy, modify, sublicense, or distribute the Program
230 except as expressly provided under this License. Any attempt
231 otherwise to copy, modify, sublicense or distribute the Program is
232 void, and will automatically terminate your rights under this License.
233 However, parties who have received copies, or rights, from you under
234 this License will not have their licenses terminated so long as such
235 parties remain in full compliance.
236
237 5. You are not required to accept this License, since you have not
238 signed it. However, nothing else grants you permission to modify or
239 distribute the Program or its derivative works. These actions are
240 prohibited by law if you do not accept this License. Therefore, by
241 modifying or distributing the Program (or any work based on the
242 Program), you indicate your acceptance of this License to do so, and
243 all its terms and conditions for copying, distributing or modifying
244 the Program or works based on it.
245
246 6. Each time you redistribute the Program (or any work based on the
247 Program), the recipient automatically receives a license from the
248 original licensor to copy, distribute or modify the Program subject to
249 these terms and conditions. You may not impose any further
250 restrictions on the recipients' exercise of the rights granted herein.
251 You are not responsible for enforcing compliance by third parties to
252 this License.
253
254 7. If, as a consequence of a court judgment or allegation of patent
255 infringement or for any other reason (not limited to patent issues),
256 conditions are imposed on you (whether by court order, agreement or
257 otherwise) that contradict the conditions of this License, they do not
258 excuse you from the conditions of this License. If you cannot
259 distribute so as to satisfy simultaneously your obligations under this
260 License and any other pertinent obligations, then as a consequence you
261 may not distribute the Program at all. For example, if a patent
262 license would not permit royalty-free redistribution of the Program by
263 all those who receive copies directly or indirectly through you, then
264 the only way you could satisfy both it and this License would be to
265 refrain entirely from distribution of the Program.
266
267 If any portion of this section is held invalid or unenforceable under
268 any particular circumstance, the balance of the section is intended to
269 apply and the section as a whole is intended to apply in other
270 circumstances.
271
272 It is not the purpose of this section to induce you to infringe any
273 patents or other property right claims or to contest validity of any
274 such claims; this section has the sole purpose of protecting the
275 integrity of the free software distribution system, which is
276 implemented by public license practices. Many people have made
277 generous contributions to the wide range of software distributed
278 through that system in reliance on consistent application of that
279 system; it is up to the author/donor to decide if he or she is willing
280 to distribute software through any other system and a licensee cannot
281 impose that choice.
282
283 This section is intended to make thoroughly clear what is believed to
284 be a consequence of the rest of this License.
285
286 8. If the distribution and/or use of the Program is restricted in
287 certain countries either by patents or by copyrighted interfaces, the
288 original copyright holder who places the Program under this License
289 may add an explicit geographical distribution limitation excluding
290 those countries, so that distribution is permitted only in or among
291 countries not thus excluded. In such case, this License incorporates
292 the limitation as if written in the body of this License.
293
294 9. The Free Software Foundation may publish revised and/or new versions
295 of the General Public License from time to time. Such new versions will
296 be similar in spirit to the present version, but may differ in detail to
297 address new problems or concerns.
298
299 Each version is given a distinguishing version number. If the Program
300 specifies a version number of this License which applies to it and "any
301 later version", you have the option of following the terms and conditions
302 either of that version or of any later version published by the Free
303 Software Foundation. If the Program does not specify a version number of
304 this License, you may choose any version ever published by the Free Software
305 Foundation.
306
307 10. If you wish to incorporate parts of the Program into other free
308 programs whose distribution conditions are different, write to the author
309 to ask for permission. For software which is copyrighted by the Free
310 Software Foundation, write to the Free Software Foundation; we sometimes
311 make exceptions for this. Our decision will be guided by the two goals
312 of preserving the free status of all derivatives of our free software and
313 of promoting the sharing and reuse of software generally.
314
315 NO WARRANTY
316
317 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
318 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
319 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
320 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
321 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
322 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
323 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
324 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
325 REPAIR OR CORRECTION.
326
327 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
328 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
329 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
330 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
331 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
332 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
333 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
334 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
335 POSSIBILITY OF SUCH DAMAGES.
336
337 END OF TERMS AND CONDITIONS
338
339 How to Apply These Terms to Your New Programs
340
341 If you develop a new program, and you want it to be of the greatest
342 possible use to the public, the best way to achieve this is to make it
343 free software which everyone can redistribute and change under these terms.
344
345 To do so, attach the following notices to the program. It is safest
346 to attach them to the start of each source file to most effectively
347 convey the exclusion of warranty; and each file should have at least
348 the "copyright" line and a pointer to where the full notice is found.
349
350 <one line to give the program's name and a brief idea of what it does.>
351 Copyright (C) <year> <name of author>
352
353 This program is free software; you can redistribute it and/or modify
354 it under the terms of the GNU General Public License as published by
355 the Free Software Foundation; either version 2 of the License, or
356 (at your option) any later version.
357
358 This program is distributed in the hope that it will be useful,
359 but WITHOUT ANY WARRANTY; without even the implied warranty of
360 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
361 GNU General Public License for more details.
362
363 You should have received a copy of the GNU General Public License
364 along with this program; if not, write to the Free Software
365 Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
366
367
368 Also add information on how to contact you by electronic and paper mail.
369
370 If the program is interactive, make it output a short notice like this
371 when it starts in an interactive mode:
372
373 Gnomovision version 69, Copyright (C) year name of author
374 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
375 This is free software, and you are welcome to redistribute it
376 under certain conditions; type `show c' for details.
377
378 The hypothetical commands `show w' and `show c' should show the appropriate
379 parts of the General Public License. Of course, the commands you use may
380 be called something other than `show w' and `show c'; they could even be
381 mouse-clicks or menu items--whatever suits your program.
382
383 You should also get your employer (if you work as a programmer) or your
384 school, if any, to sign a "copyright disclaimer" for the program, if
385 necessary. Here is a sample; alter the names:
386
387 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
388 `Gnomovision' (which makes passes at compilers) written by James Hacker.
389
390 <signature of Ty Coon>, 1 April 1989
391 Ty Coon, President of Vice
392
393 This General Public License does not permit incorporating your program into
394 proprietary programs. If your program is a subroutine library, you may
395 consider it more useful to permit linking proprietary applications with the
396 library. If this is what you want to do, use the GNU Library General
397 Public License instead of this License.
