The General Public License (GPL) |

Version 2, June 1991 |
12 |
|
13 |
Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave, |
14 |
Cambridge, MA 02139, USA. Everyone is permitted to copy and distribute |
15 |
verbatim copies of this license document, but changing it is not allowed. |
16 |
|
17 |
Preamble |
18 |
|
19 |
The licenses for most software are designed to take away your freedom to share |
20 |
and change it. By contrast, the GNU General Public License is intended to |
21 |
guarantee your freedom to share and change free software--to make sure the |
22 |
software is free for all its users. This General Public License applies to most of |
23 |
the Free Software Foundation's software and to any other program whose |
24 |
authors commit to using it. (Some other Free Software Foundation software is |
25 |
covered by the GNU Library General Public License instead.) You can apply it to |
26 |
your programs, too. |
27 |
|
28 |
When we speak of free software, we are referring to freedom, not price. Our |
29 |
General Public Licenses are designed to make sure that you have the freedom |
30 |
to distribute copies of free software (and charge for this service if you wish), that |
31 |
you receive source code or can get it if you want it, that you can change the |
32 |
software or use pieces of it in new free programs; and that you know you can do |
33 |
these things. |
34 |
|
35 |
To protect your rights, we need to make restrictions that forbid anyone to deny |
36 |
you these rights or to ask you to surrender the rights. These restrictions |
37 |
translate to certain responsibilities for you if you distribute copies of the |
38 |
software, or if you modify it. |
39 |
|
40 |
For example, if you distribute copies of such a program, whether gratis or for a |
41 |
fee, you must give the recipients all the rights that you have. You must make |
42 |
sure that they, too, receive or can get the source code. And you must show |
43 |
them these terms so they know their rights. |
44 |
|
45 |
We protect your rights with two steps: (1) copyright the software, and (2) offer |
46 |
you this license which gives you legal permission to copy, distribute and/or |
47 |
modify the software. |
48 |
|
49 |
Also, for each author's protection and ours, we want to make certain that |
50 |
everyone understands that there is no warranty for this free software. If the |
51 |
software is modified by someone else and passed on, we want its recipients to |
52 |
know that what they have is not the original, so that any problems introduced by |
53 |
others will not reflect on the original authors' reputations. |
54 |
|
55 |
Finally, any free program is threatened constantly by software patents. We wish |
56 |
to avoid the danger that redistributors of a free program will individually obtain |
57 |
patent licenses, in effect making the program proprietary. To prevent this, we |
58 |
have made it clear that any patent must be licensed for everyone's free use or |
59 |
not licensed at all. |
60 |
|
61 |
The precise terms and conditions for copying, distribution and modification |
62 |
follow. |
63 |
|
64 |
GNU GENERAL PUBLIC LICENSE |
65 |
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND |
66 |
MODIFICATION |
67 |
|
68 |
0. This License applies to any program or other work which contains a notice |
69 |
placed by the copyright holder saying it may be distributed under the terms of |
70 |
this General Public License. The "Program", below, refers to any such program |
71 |
or work, and a "work based on the Program" means either the Program or any |
72 |
derivative work under copyright law: that is to say, a work containing the |
73 |
Program or a portion of it, either verbatim or with modifications and/or translated |
74 |
into another language. (Hereinafter, translation is included without limitation in |
75 |
the term "modification".) Each licensee is addressed as "you". |
76 |
|
77 |
Activities other than copying, distribution and modification are not covered by |
78 |
this License; they are outside its scope. The act of running the Program is not |
79 |
restricted, and the output from the Program is covered only if its contents |
80 |
constitute a work based on the Program (independent of having been made by |
81 |
running the Program). Whether that is true depends on what the Program does. |
82 |
|
83 |
1. You may copy and distribute verbatim copies of the Program's source code as |
84 |
you receive it, in any medium, provided that you conspicuously and appropriately |
85 |
publish on each copy an appropriate copyright notice and disclaimer of warranty; |
86 |
keep intact all the notices that refer to this License and to the absence of any |
87 |
warranty; and give any other recipients of the Program a copy of this License |
88 |
along with the Program. |
89 |
|
90 |
You may charge a fee for the physical act of transferring a copy, and you may at |
91 |
your option offer warranty protection in exchange for a fee. |
92 |
|
93 |
2. You may modify your copy or copies of the Program or any portion of it, thus |
94 |
forming a work based on the Program, and copy and distribute such |
95 |
modifications or work under the terms of Section 1 above, provided that you also |
96 |
meet all of these conditions: |
97 |
|
98 |
a) You must cause the modified files to carry prominent notices stating that you |
99 |
changed the files and the date of any change. |
100 |
|
101 |
b) You must cause any work that you distribute or publish, that in whole or in |
102 |
part contains or is derived from the Program or any part thereof, to be licensed |
103 |
as a whole at no charge to all third parties under the terms of this License. |
104 |
|
105 |
c) If the modified program normally reads commands interactively when run, you |
106 |
must cause it, when started running for such interactive use in the most ordinary |
107 |
way, to print or display an announcement including an appropriate copyright |
108 |
notice and a notice that there is no warranty (or else, saying that you provide a |
109 |
warranty) and that users may redistribute the program under these conditions, |
110 |
and telling the user how to view a copy of this License. (Exception: if the |
111 |
Program itself is interactive but does not normally print such an announcement, |
112 |
your work based on the Program is not required to print an announcement.) |
113 |
|
114 |
These requirements apply to the modified work as a whole. If identifiable |
115 |
sections of that work are not derived from the Program, and can be reasonably |
116 |
considered independent and separate works in themselves, then this License, |
117 |
and its terms, do not apply to those sections when you distribute them as |
118 |
separate works. But when you distribute the same sections as part of a whole |
119 |
which is a work based on the Program, the distribution of the whole must be on |
120 |
the terms of this License, whose permissions for other licensees extend to the |
121 |
entire whole, and thus to each and every part regardless of who wrote it. |
122 |
|
123 |
Thus, it is not the intent of this section to claim rights or contest your rights to |
124 |
work written entirely by you; rather, the intent is to exercise the right to control |
125 |
the distribution of derivative or collective works based on the Program. |
126 |
|
127 |
In addition, mere aggregation of another work not based on the Program with the |
128 |
Program (or with a work based on the Program) on a volume of a storage or |
129 |
distribution medium does not bring the other work under the scope of this |
130 |
License. |
131 |
|
132 |
3. You may copy and distribute the Program (or a work based on it, under |
133 |
Section 2) in object code or executable form under the terms of Sections 1 and 2 |
134 |
above provided that you also do one of the following: |
135 |
|
136 |
a) Accompany it with the complete corresponding machine-readable source |
137 |
code, which must be distributed under the terms of Sections 1 and 2 above on a |
138 |
medium customarily used for software interchange; or, |
139 |
|
140 |
b) Accompany it with a written offer, valid for at least three years, to give any |
141 |
third party, for a charge no more than your cost of physically performing source |
142 |
distribution, a complete machine-readable copy of the corresponding source |
143 |
code, to be distributed under the terms of Sections 1 and 2 above on a medium |
144 |
customarily used for software interchange; or, |
145 |
|
146 |
c) Accompany it with the information you received as to the offer to distribute |
147 |
corresponding source code. (This alternative is allowed only for noncommercial |
148 |
distribution and only if you received the program in object code or executable |
149 |
form with such an offer, in accord with Subsection b above.) |
150 |
|
151 |
The source code for a work means the preferred form of the work for making |
152 |
modifications to it. For an executable work, complete source code means all the |
153 |
source code for all modules it contains, plus any associated interface definition |
154 |
files, plus the scripts used to control compilation and installation of the |
155 |
executable. However, as a special exception, the source code distributed need |
156 |
not include anything that is normally distributed (in either source or binary form) |
157 |
with the major components (compiler, kernel, and so on) of the operating system |
158 |
on which the executable runs, unless that component itself accompanies the |
159 |
executable. |
160 |
|
161 |
If distribution of executable or object code is made by offering access to copy |
162 |
from a designated place, then offering equivalent access to copy the source |
163 |
code from the same place counts as distribution of the source code, even though |
164 |
third parties are not compelled to copy the source along with the object code. |
165 |
|
166 |
4. You may not copy, modify, sublicense, or distribute the Program except as |
167 |
expressly provided under this License. Any attempt otherwise to copy, modify, |
168 |
sublicense or distribute the Program is void, and will automatically terminate |
169 |
your rights under this License. However, parties who have received copies, or |
170 |
rights, from you under this License will not have their licenses terminated so long |
171 |
as such parties remain in full compliance. |
172 |
|
173 |
5. You are not required to accept this License, since you have not signed it. |
174 |
However, nothing else grants you permission to modify or distribute the Program |
175 |
or its derivative works. These actions are prohibited by law if you do not accept |
176 |
this License. Therefore, by modifying or distributing the Program (or any work |
177 |
based on the Program), you indicate your acceptance of this License to do so, |
178 |
and all its terms and conditions for copying, distributing or modifying the |
179 |
Program or works based on it. |
180 |
|
181 |
6. Each time you redistribute the Program (or any work based on the Program), |
182 |
the recipient automatically receives a license from the original licensor to copy, |
183 |
distribute or modify the Program subject to these terms and conditions. You |
184 |
may not impose any further restrictions on the recipients' exercise of the rights |
185 |
granted herein. You are not responsible for enforcing compliance by third parties |
186 |
to this License. |
187 |
|
188 |
7. If, as a consequence of a court judgment or allegation of patent infringement |
189 |
or for any other reason (not limited to patent issues), conditions are imposed on |
190 |
you (whether by court order, agreement or otherwise) that contradict the |
191 |
conditions of this License, they do not excuse you from the conditions of this |
192 |
License. If you cannot distribute so as to satisfy simultaneously your obligations |
193 |
under this License and any other pertinent obligations, then as a consequence |
194 |
you may not distribute the Program at all. For example, if a patent license would |
195 |
not permit royalty-free redistribution of the Program by all those who receive |
196 |
copies directly or indirectly through you, then the only way you could satisfy |
197 |
both it and this License would be to refrain entirely from distribution of the |
198 |
Program. |
199 |
|
200 |
If any portion of this section is held invalid or unenforceable under any particular |
201 |
circumstance, the balance of the section is intended to apply and the section as |
202 |
a whole is intended to apply in other circumstances. |
203 |
|
204 |
It is not the purpose of this section to induce you to infringe any patents or other |
205 |
property right claims or to contest validity of any such claims; this section has |
206 |
the sole purpose of protecting the integrity of the free software distribution |
207 |
system, which is implemented by public license practices. Many people have |
208 |
made generous contributions to the wide range of software distributed through |
209 |
that system in reliance on consistent application of that system; it is up to the |
210 |
author/donor to decide if he or she is willing to distribute software through any |
211 |
other system and a licensee cannot impose that choice. |
212 |
|
213 |
This section is intended to make thoroughly clear what is believed to be a |
214 |
consequence of the rest of this License. |
215 |
|
216 |
8. If the distribution and/or use of the Program is restricted in certain countries |
217 |
either by patents or by copyrighted interfaces, the original copyright holder who |
218 |
places the Program under this License may add an explicit geographical |
219 |
distribution limitation excluding those countries, so that distribution is permitted |
220 |
only in or among countries not thus excluded. In such case, this License |
221 |
incorporates the limitation as if written in the body of this License. |
222 |
|
223 |
9. The Free Software Foundation may publish revised and/or new versions of the |
224 |
General Public License from time to time. Such new versions will be similar in |
225 |
spirit to the present version, but may differ in detail to address new problems or |
226 |
concerns. |
227 |
|
228 |
Each version is given a distinguishing version number. If the Program specifies a |
229 |
version number of this License which applies to it and "any later version", you |
230 |
have the option of following the terms and conditions either of that version or of |
231 |
any later version published by the Free Software Foundation. If the Program does |
232 |
not specify a version number of this License, you may choose any version ever |
233 |
published by the Free Software Foundation. |
234 |
|
235 |
10. If you wish to incorporate parts of the Program into other free programs |
236 |
whose distribution conditions are different, write to the author to ask for |
237 |
permission. For software which is copyrighted by the Free Software Foundation, |
238 |
write to the Free Software Foundation; we sometimes make exceptions for this. |
239 |
Our decision will be guided by the two goals of preserving the free status of all |
240 |
derivatives of our free software and of promoting the sharing and reuse of |
241 |
software generally. |
242 |
|
243 |
NO WARRANTY |
244 |
|
245 |
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS |
246 |
NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY |
247 |
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE |
248 |
COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM |
249 |
"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR |
250 |
IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF |
251 |
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE |
252 |
ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE |
253 |
PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, |
254 |
YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR |
255 |
CORRECTION. |
256 |
|
257 |
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED |
258 |
TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY |
259 |
WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS |
260 |
PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY |
261 |
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES |
262 |
ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM |
263 |
(INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING |
264 |
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD |
265 |
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY |
266 |
OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS |
267 |
BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. |
268 |
|
269 |
END OF TERMS AND CONDITIONS |

The Artistic License |
275 |
|
276 |
Preamble |
277 |
|
278 |
The intent of this document is to state the conditions under which a Package |
279 |
may be copied, such that the Copyright Holder maintains some semblance of |
280 |
artistic control over the development of the package, while giving the users of the |
281 |
package the right to use and distribute the Package in a more-or-less customary |
282 |
fashion, plus the right to make reasonable modifications. |
283 |
|
284 |
Definitions: |
285 |
|
286 |
- "Package" refers to the collection of files distributed by the Copyright |
287 |
Holder, and derivatives of that collection of files created through textual |
288 |
modification. |
289 |
- "Standard Version" refers to such a Package if it has not been modified, |
290 |
or has been modified in accordance with the wishes of the Copyright |
291 |
Holder. |
292 |
- "Copyright Holder" is whoever is named in the copyright or copyrights for |
293 |
the package. |
294 |
- "You" is you, if you're thinking about copying or distributing this Package. |
295 |
- "Reasonable copying fee" is whatever you can justify on the basis of |
296 |
media cost, duplication charges, time of people involved, and so on. (You |
297 |
will not be required to justify it to the Copyright Holder, but only to the |
298 |
computing community at large as a market that must bear the fee.) |
299 |
- "Freely Available" means that no fee is charged for the item itself, though |
300 |
there may be fees involved in handling the item. It also means that |
301 |
recipients of the item may redistribute it under the same conditions they |
302 |
received it. |
303 |
|
304 |
1. You may make and give away verbatim copies of the source form of the |
305 |
Standard Version of this Package without restriction, provided that you duplicate |
306 |
all of the original copyright notices and associated disclaimers. |
307 |
|
308 |
2. You may apply bug fixes, portability fixes and other modifications derived from |
309 |
the Public Domain or from the Copyright Holder. A Package modified in such a |
310 |
way shall still be considered the Standard Version. |
311 |
|
312 |
3. You may otherwise modify your copy of this Package in any way, provided |
313 |
that you insert a prominent notice in each changed file stating how and when |
314 |
you changed that file, and provided that you do at least ONE of the following: |
315 |
|
316 |
a) place your modifications in the Public Domain or otherwise |
317 |
make them Freely Available, such as by posting said modifications |
318 |
to Usenet or an equivalent medium, or placing the modifications on |
319 |
a major archive site such as ftp.uu.net, or by allowing the |
320 |
Copyright Holder to include your modifications in the Standard |
321 |
Version of the Package. |
322 |
|
323 |
b) use the modified Package only within your corporation or |
324 |
organization. |
325 |
|
326 |
c) rename any non-standard executables so the names do not |
327 |
conflict with standard executables, which must also be provided, |
328 |
and provide a separate manual page for each non-standard |
329 |
executable that clearly documents how it differs from the Standard |
330 |
Version. |
331 |
|
332 |
d) make other distribution arrangements with the Copyright Holder. |
333 |
|
334 |
4. You may distribute the programs of this Package in object code or executable |
335 |
form, provided that you do at least ONE of the following: |
336 |
|
337 |
a) distribute a Standard Version of the executables and library |
338 |
files, together with instructions (in the manual page or equivalent) |
339 |
on where to get the Standard Version. |
340 |
|
341 |
b) accompany the distribution with the machine-readable source of |
342 |
the Package with your modifications. |
343 |
|
344 |
c) accompany any non-standard executables with their |
345 |
corresponding Standard Version executables, giving the |
346 |
non-standard executables non-standard names, and clearly |
347 |
documenting the differences in manual pages (or equivalent), |
348 |
together with instructions on where to get the Standard Version. |
349 |
|
350 |
d) make other distribution arrangements with the Copyright Holder. |
351 |
|
352 |
5. You may charge a reasonable copying fee for any distribution of this Package. |
353 |
You may charge any fee you choose for support of this Package. You may not |
354 |
charge a fee for this Package itself. However, you may distribute this Package in |
355 |
aggregate with other (possibly commercial) programs as part of a larger |
356 |
(possibly commercial) software distribution provided that you do not advertise |
357 |
this Package as a product of your own. |
358 |
|
359 |
6. The scripts and library files supplied as input to or produced as output from |
360 |
the programs of this Package do not automatically fall under the copyright of this |
361 |
Package, but belong to whomever generated them, and may be sold |
362 |
commercially, and may be aggregated with this Package. |
363 |
|
364 |
7. C or perl subroutines supplied by you and linked into this Package shall not |
365 |
be considered part of this Package. |
366 |
|
367 |
8. Aggregation of this Package with a commercial distribution is always permitted |
368 |
provided that the use of this Package is embedded; that is, when no overt attempt |
369 |
is made to make this Package's interfaces visible to the end user of the |
370 |
commercial distribution. Such use shall not be construed as a distribution of |
371 |
this Package. |
372 |
|
373 |
9. The name of the Copyright Holder may not be used to endorse or promote |
374 |
products derived from this software without specific prior written permission. |
375 |
|
376 |
10. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR |
377 |
IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED |
378 |
WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR |
379 |
PURPOSE. |
