|
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
|
|
|
|
5
|
+ Everyone is permitted to copy and distribute verbatim copies
|
|
|
|
6
|
+ of this license document, but changing it is not allowed.
|

|

|
|
|
|
8
|
+ Preamble
|
|
|
|
9
|
+
|
|
|
|
10
|
+ The GNU General Public License is a free, copyleft license for
|
|
|
|
11
|
+software and other kinds of works.
|
|
|
|
12
|
+
|
|
|
|
13
|
+ The licenses for most software and other practical works are designed
|
|
|
|
14
|
+to take away your freedom to share and change the works. By contrast,
|
|
|
|
15
|
+the GNU General Public License is intended to guarantee your freedom to
|
|
|
|
16
|
+share and change all versions of a program--to make sure it remains free
|
|
|
|
17
|
+software for all its users. We, the Free Software Foundation, use the
|
|
|
|
18
|
+GNU General Public License for most of our software; it applies also to
|
|
|
|
19
|
+any other work released this way by its authors. You can apply it to
|
|
|
|
20
|
+your programs, too.
|
|
|
|
21
|
+
|
|
|
|
22
|
+ When we speak of free software, we are referring to freedom, not
|
|
|
|
23
|
+price. Our General Public Licenses are designed to make sure that you
|
|
|
|
24
|
+have the freedom to distribute copies of free software (and charge for
|
|
|
|
25
|
+them if you wish), that you receive source code or can get it if you
|
|
|
|
26
|
+want it, that you can change the software or use pieces of it in new
|
|
|
|
27
|
+free programs, and that you know you can do these things.
|
|
|
|
28
|
+
|
|
|
|
29
|
+ To protect your rights, we need to prevent others from denying you
|
|
|
|
30
|
+these rights or asking you to surrender the rights. Therefore, you have
|
|
|
|
31
|
+certain responsibilities if you distribute copies of the software, or if
|
|
|
|
32
|
+you modify it: responsibilities to respect the freedom of others.
|
|
|
|
33
|
+
|
|
|
|
34
|
+ For example, if you distribute copies of such a program, whether
|
|
|
|
35
|
+gratis or for a fee, you must pass on to the recipients the same
|
|
|
|
36
|
+freedoms that you received. You must make sure that they, too, receive
|
|
|
|
37
|
+or can get the source code. And you must show them these terms so they
|
|
|
|
38
|
+know their rights.
|
|
|
|
39
|
+
|
|
|
|
40
|
+ Developers that use the GNU GPL protect your rights with two steps:
|
|
|
|
41
|
+(1) assert copyright on the software, and (2) offer you this License
|
|
|
|
42
|
+giving you legal permission to copy, distribute and/or modify it.
|
|
|
|
43
|
+
|
|
|
|
44
|
+ For the developers' and authors' protection, the GPL clearly explains
|
|
|
|
45
|
+that there is no warranty for this free software. For both users' and
|
|
|
|
46
|
+authors' sake, the GPL requires that modified versions be marked as
|
|
|
|
47
|
+changed, so that their problems will not be attributed erroneously to
|
|
|
|
48
|
+authors of previous versions.
|
|
|
|
49
|
+
|
|
|
|
50
|
+ Some devices are designed to deny users access to install or run
|
|
|
|
51
|
+modified versions of the software inside them, although the manufacturer
|
|
|
|
52
|
+can do so. This is fundamentally incompatible with the aim of
|
|
|
|
53
|
+protecting users' freedom to change the software. The systematic
|
|
|
|
54
|
+pattern of such abuse occurs in the area of products for individuals to
|
|
|
|
55
|
+use, which is precisely where it is most unacceptable. Therefore, we
|
|
|
|
56
|
+have designed this version of the GPL to prohibit the practice for those
|
|
|
|
57
|
+products. If such problems arise substantially in other domains, we
|
|
|
|
58
|
+stand ready to extend this provision to those domains in future versions
|
|
|
|
59
|
+of the GPL, as needed to protect the freedom of users.
|
|
|
|
60
|
+
|
|
|
|
61
|
+ Finally, every program is threatened constantly by software patents.
|
|
|
|
62
|
+States should not allow patents to restrict development and use of
|
|
|
|
63
|
+software on general-purpose computers, but in those that do, we wish to
|
|
|
|
64
|
+avoid the special danger that patents applied to a free program could
|
|
|
|
65
|
+make it effectively proprietary. To prevent this, the GPL assures that
|
|
|
|
66
|
+patents cannot be used to render the program non-free.
|
|
|
|
67
|
+
|
|
|
|
68
|
+ The precise terms and conditions for copying, distribution and
|
|
|
|
69
|
+modification follow.

|
|
|
|
71
|
+ TERMS AND CONDITIONS
|
|
|
|
72
|
+
|
|
|
|
73
|
+ 0. Definitions.
|
|
|
|
74
|
+
|
|
|
|
75
|
+ "This License" refers to version 3 of the GNU General Public License.
|
|
|
|
76
|
+
|
|
|
|
77
|
+ "Copyright" also means copyright-like laws that apply to other kinds of
|
|
|
|
78
|
+works, such as semiconductor masks.
|
|
|
|
79
|
+
|
|
|
|
80
|
+ "The Program" refers to any copyrightable work licensed under this
|
|
|
|
81
|
+License. Each licensee is addressed as "you". "Licensees" and
|
|
|
|
82
|
+"recipients" may be individuals or organizations.
|
|
|
|
83
|
+
|
|
|
|
84
|
+ To "modify" a work means to copy from or adapt all or part of the work
|
|
|
|
85
|
+in a fashion requiring copyright permission, other than the making of an
|
|
|
|
86
|
+exact copy. The resulting work is called a "modified version" of the
|
|
|
|
87
|
+earlier work or a work "based on" the earlier work.
|
|
|
|
88
|
+
|
|
|
|
89
|
+ A "covered work" means either the unmodified Program or a work based
|
|
|
|
90
|
+on the Program.
|
|
|
|
91
|
+
|
|
|
|
92
|
+ To "propagate" a work means to do anything with it that, without
|
|
|
|
93
|
+permission, would make you directly or secondarily liable for
|
|
|
|
94
|
+infringement under applicable copyright law, except executing it on a
|
|
|
|
95
|
+computer or modifying a private copy. Propagation includes copying,
|
|
|
|
96
|
+distribution (with or without modification), making available to the
|
|
|
|
97
|
+public, and in some countries other activities as well.
|
|
|
|
98
|
+
|
|
|
|
99
|
+ To "convey" a work means any kind of propagation that enables other
|
|
|
|
100
|
+parties to make or receive copies. Mere interaction with a user through
|
|
|
|
101
|
+a computer network, with no transfer of a copy, is not conveying.
|
|
|
|
102
|
+
|
|
|
|
103
|
+ An interactive user interface displays "Appropriate Legal Notices"
|
|
|
|
104
|
+to the extent that it includes a convenient and prominently visible
|
|
|
|
105
|
+feature that (1) displays an appropriate copyright notice, and (2)
|
|
|
|
106
|
+tells the user that there is no warranty for the work (except to the
|
|
|
|
107
|
+extent that warranties are provided), that licensees may convey the
|
|
|
|
108
|
+work under this License, and how to view a copy of this License. If
|
|
|
|
109
|
+the interface presents a list of user commands or options, such as a
|
|
|
|
110
|
+menu, a prominent item in the list meets this criterion.
|
|
|
|
111
|
+
|
|
|
|
112
|
+ 1. Source Code.
|
|
|
|
113
|
+
|
|
|
|
114
|
+ The "source code" for a work means the preferred form of the work
|
|
|
|
115
|
+for making modifications to it. "Object code" means any non-source
|
|
|
|
116
|
+form of a work.
|
|
|
|
117
|
+
|
|
|
|
118
|
+ A "Standard Interface" means an interface that either is an official
|
|
|
|
119
|
+standard defined by a recognized standards body, or, in the case of
|
|
|
|
120
|
+interfaces specified for a particular programming language, one that
|
|
|
|
121
|
+is widely used among developers working in that language.
|
|
|
|
122
|
+
|
|
|
|
123
|
+ The "System Libraries" of an executable work include anything, other
|
|
|
|
124
|
+than the work as a whole, that (a) is included in the normal form of
|
|
|
|
125
|
+packaging a Major Component, but which is not part of that Major
|
|
|
|
126
|
+Component, and (b) serves only to enable use of the work with that
|
|
|
|
127
|
+Major Component, or to implement a Standard Interface for which an
|
|
|
|
128
|
+implementation is available to the public in source code form. A
|
|
|
|
129
|
+"Major Component", in this context, means a major essential component
|
|
|
|
130
|
+(kernel, window system, and so on) of the specific operating system
|
|
|
|
131
|
+(if any) on which the executable work runs, or a compiler used to
|
|
|
|
132
|
+produce the work, or an object code interpreter used to run it.
|
|
|
|
133
|
+
|
|
|
|
134
|
+ The "Corresponding Source" for a work in object code form means all
|
|
|
|
135
|
+the source code needed to generate, install, and (for an executable
|
|
|
|
136
|
+work) run the object code and to modify the work, including scripts to
|
|
|
|
137
|
+control those activities. However, it does not include the work's
|
|
|
|
138
|
+System Libraries, or general-purpose tools or generally available free
|
|
|
|
139
|
+programs which are used unmodified in performing those activities but
|
|
|
|
140
|
+which are not part of the work. For example, Corresponding Source
|
|
|
|
141
|
+includes interface definition files associated with source files for
|
|
|
|
142
|
+the work, and the source code for shared libraries and dynamically
|
|
|
|
143
|
+linked subprograms that the work is specifically designed to require,
|
|
|
|
144
|
+such as by intimate data communication or control flow between those
|
|
|
|
145
|
+subprograms and other parts of the work.
|
|
|
|
146
|
+
|
|
|
|
147
|
+ The Corresponding Source need not include anything that users
|
|
|
|
148
|
+can regenerate automatically from other parts of the Corresponding
|
|
|
|
149
|
+Source.
|
|
|
|
150
|
+
|
|
|
|
151
|
+ The Corresponding Source for a work in source code form is that
|
|
|
|
152
|
+same work.
|
|
|
|
153
|
+
|
|
|
|
154
|
+ 2. Basic Permissions.
|
|
|
|
155
|
+
|
|
|
|
156
|
+ All rights granted under this License are granted for the term of
|
|
|
|
157
|
+copyright on the Program, and are irrevocable provided the stated
|
|
|
|
158
|
+conditions are met. This License explicitly affirms your unlimited
|
|
|
|
159
|
+permission to run the unmodified Program. The output from running a
|
|
|
|
160
|
+covered work is covered by this License only if the output, given its
|
|
|
|
161
|
+content, constitutes a covered work. This License acknowledges your
|
|
|
|
162
|
+rights of fair use or other equivalent, as provided by copyright law.
|
|
|
|
163
|
+
|
|
|
|
164
|
+ You may make, run and propagate covered works that you do not
|
|
|
|
165
|
+convey, without conditions so long as your license otherwise remains
|
|
|
|
166
|
+in force. You may convey covered works to others for the sole purpose
|
|
|
|
167
|
+of having them make modifications exclusively for you, or provide you
|
|
|
|
168
|
+with facilities for running those works, provided that you comply with
|
|
|
|
169
|
+the terms of this License in conveying all material for which you do
|
|
|
|
170
|
+not control copyright. Those thus making or running the covered works
|
|
|
|
171
|
+for you must do so exclusively on your behalf, under your direction
|
|
|
|
172
|
+and control, on terms that prohibit them from making any copies of
|
|
|
|
173
|
+your copyrighted material outside their relationship with you.
|
|
|
|
174
|
+
|
|
|
|
175
|
+ Conveying under any other circumstances is permitted solely under
|
|
|
|
176
|
+the conditions stated below. Sublicensing is not allowed; section 10
|
|
|
|
177
|
+makes it unnecessary.
|
|
|
|
178
|
+
|
|
|
|
179
|
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
|
|
|
180
|
+
|
|
|
|
181
|
+ No covered work shall be deemed part of an effective technological
|
|
|
|
182
|
+measure under any applicable law fulfilling obligations under article
|
|
|
|
183
|
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
|
|
|
184
|
+similar laws prohibiting or restricting circumvention of such
|
|
|
|
185
|
+measures.
|
|
|
|
186
|
+
|
|
|
|
187
|
+ When you convey a covered work, you waive any legal power to forbid
|
|
|
|
188
|
+circumvention of technological measures to the extent such circumvention
|
|
|
|
189
|
+is effected by exercising rights under this License with respect to
|
|
|
|
190
|
+the covered work, and you disclaim any intention to limit operation or
|
|
|
|
191
|
+modification of the work as a means of enforcing, against the work's
|
|
|
|
192
|
+users, your or third parties' legal rights to forbid circumvention of
|
|
|
|
193
|
+technological measures.
|
|
|
|
194
|
+
|
|
|
|
195
|
+ 4. Conveying Verbatim Copies.
|
|
|
|
196
|
+
|
|
|
|
197
|
+ You may convey verbatim copies of the Program's source code as you
|
|
|
|
198
|
+receive it, in any medium, provided that you conspicuously and
|
|
|
|
199
|
+appropriately publish on each copy an appropriate copyright notice;
|
|
|
|
200
|
+keep intact all notices stating that this License and any
|
|
|
|
201
|
+non-permissive terms added in accord with section 7 apply to the code;
|
|
|
|
202
|
+keep intact all notices of the absence of any warranty; and give all
|
|
|
|
203
|
+recipients a copy of this License along with the Program.
|
|
|
|
204
|
+
|
|
|
|
205
|
+ You may charge any price or no price for each copy that you convey,
|
|
|
|
206
|
+and you may offer support or warranty protection for a fee.
|
|
|
|
207
|
+
|
|
|
|
208
|
+ 5. Conveying Modified Source Versions.
|
|
|
|
209
|
+
|
|
|
|
210
|
+ You may convey a work based on the Program, or the modifications to
|
|
|
|
211
|
+produce it from the Program, in the form of source code under the
|
|
|
|
212
|
+terms of section 4, provided that you also meet all of these conditions:
|
|
|
|
213
|
+
|
|
|
|
214
|
+ a) The work must carry prominent notices stating that you modified
|
|
|
|
215
|
+ it, and giving a relevant date.
|
|
|
|
216
|
+
|
|
|
|
217
|
+ b) The work must carry prominent notices stating that it is
|
|
|
|
218
|
+ released under this License and any conditions added under section
|
|
|
|
219
|
+ 7. This requirement modifies the requirement in section 4 to
|
|
|
|
220
|
+ "keep intact all notices".
|
|
|
|
221
|
+
|
|
|
|
222
|
+ c) You must license the entire work, as a whole, under this
|
|
|
|
223
|
+ License to anyone who comes into possession of a copy. This
|
|
|
|
224
|
+ License will therefore apply, along with any applicable section 7
|
|
|
|
225
|
+ additional terms, to the whole of the work, and all its parts,
|
|
|
|
226
|
+ regardless of how they are packaged. This License gives no
|
|
|
|
227
|
+ permission to license the work in any other way, but it does not
|
|
|
|
228
|
+ invalidate such permission if you have separately received it.
|
|
|
|
229
|
+
|
|
|
|
230
|
+ d) If the work has interactive user interfaces, each must display
|
|
|
|
231
|
+ Appropriate Legal Notices; however, if the Program has interactive
|
|
|
|
232
|
+ interfaces that do not display Appropriate Legal Notices, your
|
|
|
|
233
|
+ work need not make them do so.
|
|
|
|
234
|
+
|
|
|
|
235
|
+ A compilation of a covered work with other separate and independent
|
|
|
|
236
|
+works, which are not by their nature extensions of the covered work,
|
|
|
|
237
|
+and which are not combined with it such as to form a larger program,
|
|
|
|
238
|
+in or on a volume of a storage or distribution medium, is called an
|
|
|
|
239
|
+"aggregate" if the compilation and its resulting copyright are not
|
|
|
|
240
|
+used to limit the access or legal rights of the compilation's users
|
|
|
|
241
|
+beyond what the individual works permit. Inclusion of a covered work
|
|
|
|
242
|
+in an aggregate does not cause this License to apply to the other
|
|
|
|
243
|
+parts of the aggregate.
|
|
|
|
244
|
+
|
|
|
|
245
|
+ 6. Conveying Non-Source Forms.
|
|
|
|
246
|
+
|
|
|
|
247
|
+ You may convey a covered work in object code form under the terms
|
|
|
|
248
|
+of sections 4 and 5, provided that you also convey the
|
|
|
|
249
|
+machine-readable Corresponding Source under the terms of this License,
|
|
|
|
250
|
+in one of these ways:
|
|
|
|
251
|
+
|
|
|
|
252
|
+ a) Convey the object code in, or embodied in, a physical product
|
|
|
|
253
|
+ (including a physical distribution medium), accompanied by the
|
|
|
|
254
|
+ Corresponding Source fixed on a durable physical medium
|
|
|
|
255
|
+ customarily used for software interchange.
|
|
|
|
256
|
+
|
|
|
|
257
|
+ b) Convey the object code in, or embodied in, a physical product
|
|
|
|
258
|
+ (including a physical distribution medium), accompanied by a
|
|
|
|
259
|
+ written offer, valid for at least three years and valid for as
|
|
|
|
260
|
+ long as you offer spare parts or customer support for that product
|
|
|
|
261
|
+ model, to give anyone who possesses the object code either (1) a
|
|
|
|
262
|
+ copy of the Corresponding Source for all the software in the
|
|
|
|
263
|
+ product that is covered by this License, on a durable physical
|
|
|
|
264
|
+ medium customarily used for software interchange, for a price no
|
|
|
|
265
|
+ more than your reasonable cost of physically performing this
|
|
|
|
266
|
+ conveying of source, or (2) access to copy the
|
|
|
|
267
|
+ Corresponding Source from a network server at no charge.
|
|
|
|
268
|
+
|
|
|
|
269
|
+ c) Convey individual copies of the object code with a copy of the
|
|
|
|
270
|
+ written offer to provide the Corresponding Source. This
|
|
|
|
271
|
+ alternative is allowed only occasionally and noncommercially, and
|
|
|
|
272
|
+ only if you received the object code with such an offer, in accord
|
|
|
|
273
|
+ with subsection 6b.
|
|
|
|
274
|
+
|
|
|
|
275
|
+ d) Convey the object code by offering access from a designated
|
|
|
|
276
|
+ place (gratis or for a charge), and offer equivalent access to the
|
|
|
|
277
|
+ Corresponding Source in the same way through the same place at no
|
|
|
|
278
|
+ further charge. You need not require recipients to copy the
|
|
|
|
279
|
+ Corresponding Source along with the object code. If the place to
|
|
|
|
280
|
+ copy the object code is a network server, the Corresponding Source
|
|
|
|
281
|
+ may be on a different server (operated by you or a third party)
|
|
|
|
282
|
+ that supports equivalent copying facilities, provided you maintain
|
|
|
|
283
|
+ clear directions next to the object code saying where to find the
|
|
|
|
284
|
+ Corresponding Source. Regardless of what server hosts the
|
|
|
|
285
|
+ Corresponding Source, you remain obligated to ensure that it is
|
|
|
|
286
|
+ available for as long as needed to satisfy these requirements.
|
|
|
|
287
|
+
|
|
|
|
288
|
+ e) Convey the object code using peer-to-peer transmission, provided
|
|
|
|
289
|
+ you inform other peers where the object code and Corresponding
|
|
|
|
290
|
+ Source of the work are being offered to the general public at no
|
|
|
|
291
|
+ charge under subsection 6d.
|
|
|
|
292
|
+
|
|
|
|
293
|
+ A separable portion of the object code, whose source code is excluded
|
|
|
|
294
|
+from the Corresponding Source as a System Library, need not be
|
|
|
|
295
|
+included in conveying the object code work.
|
|
|
|
296
|
+
|
|
|
|
297
|
+ A "User Product" is either (1) a "consumer product", which means any
|
|
|
|
298
|
+tangible personal property which is normally used for personal, family,
|
|
|
|
299
|
+or household purposes, or (2) anything designed or sold for incorporation
|
|
|
|
300
|
+into a dwelling. In determining whether a product is a consumer product,
|
|
|
|
301
|
+doubtful cases shall be resolved in favor of coverage. For a particular
|
|
|
|
302
|
+product received by a particular user, "normally used" refers to a
|
|
|
|
303
|
+typical or common use of that class of product, regardless of the status
|
|
|
|
304
|
+of the particular user or of the way in which the particular user
|
|
|
|
305
|
+actually uses, or expects or is expected to use, the product. A product
|
|
|
|
306
|
+is a consumer product regardless of whether the product has substantial
|
|
|
|
307
|
+commercial, industrial or non-consumer uses, unless such uses represent
|
|
|
|
308
|
+the only significant mode of use of the product.
|
|
|
|
309
|
+
|
|
|
|
310
|
+ "Installation Information" for a User Product means any methods,
|
|
|
|
311
|
+procedures, authorization keys, or other information required to install
|
|
|
|
312
|
+and execute modified versions of a covered work in that User Product from
|
|
|
|
313
|
+a modified version of its Corresponding Source. The information must
|
|
|
|
314
|
+suffice to ensure that the continued functioning of the modified object
|
|
|
|
315
|
+code is in no case prevented or interfered with solely because
|
|
|
|
316
|
+modification has been made.
|
|
|
|
317
|
+
|
|
|
|
318
|
+ If you convey an object code work under this section in, or with, or
|
|
|
|
319
|
+specifically for use in, a User Product, and the conveying occurs as
|
|
|
|
320
|
+part of a transaction in which the right of possession and use of the
|
|
|
|
321
|
+User Product is transferred to the recipient in perpetuity or for a
|
|
|
|
322
|
+fixed term (regardless of how the transaction is characterized), the
|
|
|
|
323
|
+Corresponding Source conveyed under this section must be accompanied
|
|
|
|
324
|
+by the Installation Information. But this requirement does not apply
|
|
|
|
325
|
+if neither you nor any third party retains the ability to install
|
|
|
|
326
|
+modified object code on the User Product (for example, the work has
|
|
|
|
327
|
+been installed in ROM).
|
|
|
|
328
|
+
|
|
|
|
329
|
+ The requirement to provide Installation Information does not include a
|
|
|
|
330
|
+requirement to continue to provide support service, warranty, or updates
|
|
|
|
331
|
+for a work that has been modified or installed by the recipient, or for
|
|
|
|
332
|
+the User Product in which it has been modified or installed. Access to a
|
|
|
|
333
|
+network may be denied when the modification itself materially and
|
|
|
|
334
|
+adversely affects the operation of the network or violates the rules and
|
|
|
|
335
|
+protocols for communication across the network.
|
|
|
|
336
|
+
|
|
|
|
337
|
+ Corresponding Source conveyed, and Installation Information provided,
|
|
|
|
338
|
+in accord with this section must be in a format that is publicly
|
|
|
|
339
|
+documented (and with an implementation available to the public in
|
|
|
|
340
|
+source code form), and must require no special password or key for
|
|
|
|
341
|
+unpacking, reading or copying.
|
|
|
|
342
|
+
|
|
|
|
343
|
+ 7. Additional Terms.
|
|
|
|
344
|
+
|
|
|
|
345
|
+ "Additional permissions" are terms that supplement the terms of this
|
|
|
|
346
|
+License by making exceptions from one or more of its conditions.
|
|
|
|
347
|
+Additional permissions that are applicable to the entire Program shall
|
|
|
|
348
|
+be treated as though they were included in this License, to the extent
|
|
|
|
349
|
+that they are valid under applicable law. If additional permissions
|
|
|
|
350
|
+apply only to part of the Program, that part may be used separately
|
|
|
|
351
|
+under those permissions, but the entire Program remains governed by
|
|
|
|
352
|
+this License without regard to the additional permissions.
|
|
|
|
353
|
+
|
|
|
|
354
|
+ When you convey a copy of a covered work, you may at your option
|
|
|
|
355
|
+remove any additional permissions from that copy, or from any part of
|
|
|
|
356
|
+it. (Additional permissions may be written to require their own
|
|
|
|
357
|
+removal in certain cases when you modify the work.) You may place
|
|
|
|
358
|
+additional permissions on material, added by you to a covered work,
|
|
|
|
359
|
+for which you have or can give appropriate copyright permission.
|
|
|
|
360
|
+
|
|
|
|
361
|
+ Notwithstanding any other provision of this License, for material you
|
|
|
|
362
|
+add to a covered work, you may (if authorized by the copyright holders of
|
|
|
|
363
|
+that material) supplement the terms of this License with terms:
|
|
|
|
364
|
+
|
|
|
|
365
|
+ a) Disclaiming warranty or limiting liability differently from the
|
|
|
|
366
|
+ terms of sections 15 and 16 of this License; or
|
|
|
|
367
|
+
|
|
|
|
368
|
+ b) Requiring preservation of specified reasonable legal notices or
|
|
|
|
369
|
+ author attributions in that material or in the Appropriate Legal
|
|
|
|
370
|
+ Notices displayed by works containing it; or
|
|
|
|
371
|
+
|
|
|
|
372
|
+ c) Prohibiting misrepresentation of the origin of that material, or
|
|
|
|
373
|
+ requiring that modified versions of such material be marked in
|
|
|
|
374
|
+ reasonable ways as different from the original version; or
|
|
|
|
375
|
+
|
|
|
|
376
|
+ d) Limiting the use for publicity purposes of names of licensors or
|
|
|
|
377
|
+ authors of the material; or
|
|
|
|
378
|
+
|
|
|
|
379
|
+ e) Declining to grant rights under trademark law for use of some
|
|
|
|
380
|
+ trade names, trademarks, or service marks; or
|
|
|
|
381
|
+
|
|
|
|
382
|
+ f) Requiring indemnification of licensors and authors of that
|
|
|
|
383
|
+ material by anyone who conveys the material (or modified versions of
|
|
|
|
384
|
+ it) with contractual assumptions of liability to the recipient, for
|
|
|
|
385
|
+ any liability that these contractual assumptions directly impose on
|
|
|
|
386
|
+ those licensors and authors.
|
|
|
|
387
|
+
|
|
|
|
388
|
+ All other non-permissive additional terms are considered "further
|
|
|
|
389
|
+restrictions" within the meaning of section 10. If the Program as you
|
|
|
|
390
|
+received it, or any part of it, contains a notice stating that it is
|
|
|
|
391
|
+governed by this License along with a term that is a further
|
|
|
|
392
|
+restriction, you may remove that term. If a license document contains
|
|
|
|
393
|
+a further restriction but permits relicensing or conveying under this
|
|
|
|
394
|
+License, you may add to a covered work material governed by the terms
|
|
|
|
395
|
+of that license document, provided that the further restriction does
|
|
|
|
396
|
+not survive such relicensing or conveying.
|
|
|
|
397
|
+
|
|
|
|
398
|
+ If you add terms to a covered work in accord with this section, you
|
|
|
|
399
|
+must place, in the relevant source files, a statement of the
|
|
|
|
400
|
+additional terms that apply to those files, or a notice indicating
|
|
|
|
401
|
+where to find the applicable terms.
|
|
|
|
402
|
+
|
|
|
|
403
|
+ Additional terms, permissive or non-permissive, may be stated in the
|
|
|
|
404
|
+form of a separately written license, or stated as exceptions;
|
|
|
|
405
|
+the above requirements apply either way.
|
|
|
|
406
|
+
|
|
|
|
407
|
+ 8. Termination.
|
|
|
|
408
|
+
|
|
|
|
409
|
+ You may not propagate or modify a covered work except as expressly
|
|
|
|
410
|
+provided under this License. Any attempt otherwise to propagate or
|
|
|
|
411
|
+modify it is void, and will automatically terminate your rights under
|
|
|
|
412
|
+this License (including any patent licenses granted under the third
|
|
|
|
413
|
+paragraph of section 11).
|
|
|
|
414
|
+
|
|
|
|
415
|
+ However, if you cease all violation of this License, then your
|
|
|
|
416
|
+license from a particular copyright holder is reinstated (a)
|
|
|
|
417
|
+provisionally, unless and until the copyright holder explicitly and
|
|
|
|
418
|
+finally terminates your license, and (b) permanently, if the copyright
|
|
|
|
419
|
+holder fails to notify you of the violation by some reasonable means
|
|
|
|
420
|
+prior to 60 days after the cessation.
|
|
|
|
421
|
+
|
|
|
|
422
|
+ Moreover, your license from a particular copyright holder is
|
|
|
|
423
|
+reinstated permanently if the copyright holder notifies you of the
|
|
|
|
424
|
+violation by some reasonable means, this is the first time you have
|
|
|
|
425
|
+received notice of violation of this License (for any work) from that
|
|
|
|
426
|
+copyright holder, and you cure the violation prior to 30 days after
|
|
|
|
427
|
+your receipt of the notice.
|
|
|
|
428
|
+
|
|
|
|
429
|
+ Termination of your rights under this section does not terminate the
|
|
|
|
430
|
+licenses of parties who have received copies or rights from you under
|
|
|
|
431
|
+this License. If your rights have been terminated and not permanently
|
|
|
|
432
|
+reinstated, you do not qualify to receive new licenses for the same
|
|
|
|
433
|
+material under section 10.
|
|
|
|
434
|
+
|
|
|
|
435
|
+ 9. Acceptance Not Required for Having Copies.
|
|
|
|
436
|
+
|
|
|
|
437
|
+ You are not required to accept this License in order to receive or
|
|
|
|
438
|
+run a copy of the Program. Ancillary propagation of a covered work
|
|
|
|
439
|
+occurring solely as a consequence of using peer-to-peer transmission
|
|
|
|
440
|
+to receive a copy likewise does not require acceptance. However,
|
|
|
|
441
|
+nothing other than this License grants you permission to propagate or
|
|
|
|
442
|
+modify any covered work. These actions infringe copyright if you do
|
|
|
|
443
|
+not accept this License. Therefore, by modifying or propagating a
|
|
|
|
444
|
+covered work, you indicate your acceptance of this License to do so.
|
|
|
|
445
|
+
|
|
|
|
446
|
+ 10. Automatic Licensing of Downstream Recipients.
|
|
|
|
447
|
+
|
|
|
|
448
|
+ Each time you convey a covered work, the recipient automatically
|
|
|
|
449
|
+receives a license from the original licensors, to run, modify and
|
|
|
|
450
|
+propagate that work, subject to this License. You are not responsible
|
|
|
|
451
|
+for enforcing compliance by third parties with this License.
|
|
|
|
452
|
+
|
|
|
|
453
|
+ An "entity transaction" is a transaction transferring control of an
|
|
|
|
454
|
+organization, or substantially all assets of one, or subdividing an
|
|
|
|
455
|
+organization, or merging organizations. If propagation of a covered
|
|
|
|
456
|
+work results from an entity transaction, each party to that
|
|
|
|
457
|
+transaction who receives a copy of the work also receives whatever
|
|
|
|
458
|
+licenses to the work the party's predecessor in interest had or could
|
|
|
|
459
|
+give under the previous paragraph, plus a right to possession of the
|
|
|
|
460
|
+Corresponding Source of the work from the predecessor in interest, if
|
|
|
|
461
|
+the predecessor has it or can get it with reasonable efforts.
|
|
|
|
462
|
+
|
|
|
|
463
|
+ You may not impose any further restrictions on the exercise of the
|
|
|
|
464
|
+rights granted or affirmed under this License. For example, you may
|
|
|
|
465
|
+not impose a license fee, royalty, or other charge for exercise of
|
|
|
|
466
|
+rights granted under this License, and you may not initiate litigation
|
|
|
|
467
|
+(including a cross-claim or counterclaim in a lawsuit) alleging that
|
|
|
|
468
|
+any patent claim is infringed by making, using, selling, offering for
|
|
|
|
469
|
+sale, or importing the Program or any portion of it.
|
|
|
|
470
|
+
|
|
|
|
471
|
+ 11. Patents.
|
|
|
|
472
|
+
|
|
|
|
473
|
+ A "contributor" is a copyright holder who authorizes use under this
|
|
|
|
474
|
+License of the Program or a work on which the Program is based. The
|
|
|
|
475
|
+work thus licensed is called the contributor's "contributor version".
|
|
|
|
476
|
+
|
|
|
|
477
|
+ A contributor's "essential patent claims" are all patent claims
|
|
|
|
478
|
+owned or controlled by the contributor, whether already acquired or
|
|
|
|
479
|
+hereafter acquired, that would be infringed by some manner, permitted
|
|
|
|
480
|
+by this License, of making, using, or selling its contributor version,
|
|
|
|
481
|
+but do not include claims that would be infringed only as a
|
|
|
|
482
|
+consequence of further modification of the contributor version. For
|
|
|
|
483
|
+purposes of this definition, "control" includes the right to grant
|
|
|
|
484
|
+patent sublicenses in a manner consistent with the requirements of
|
|
|
|
485
|
+this License.
|
|
|
|
486
|
+
|
|
|
|
487
|
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
|
|
|
|
488
|
+patent license under the contributor's essential patent claims, to

|
|
|
491
|

|
|
|
|
492
|
+ In the following three paragraphs, a "patent license" is any express
|
|
|
|
493
|
+agreement or commitment, however denominated, not to enforce a patent
|
|
|
|
494
|
+(such as an express permission to practice a patent or covenant not to
|
|
|
|
495
|
+sue for patent infringement). To "grant" such a patent license to a
|
|
|
|
496
|
+party means to make such an agreement or commitment not to enforce a
|
|
|
|
497
|
+patent against the party.
|
|
|
|
498
|
+
|
|
|
|
499
|
+ If you convey a covered work, knowingly relying on a patent license,
|
|
|
|
500
|
+and the Corresponding Source of the work is not available for anyone
|
|
|
|
501
|
+to copy, free of charge and under the terms of this License, through a
|
|
|
|
502
|
+publicly available network server or other readily accessible means,
|
|
|
|
503
|
+then you must either (1) cause the Corresponding Source to be so
|
|
|
|
504
|
+available, or (2) arrange to deprive yourself of the benefit of the
|
|
|
|
505
|
+patent license for this particular work, or (3) arrange, in a manner
|
|
|
|
506
|
+consistent with the requirements of this License, to extend the patent
|
|
|
|
507
|
+license to downstream recipients. "Knowingly relying" means you have
|
|
|
|
508
|
+actual knowledge that, but for the patent license, your conveying the
|
|
|
|
509
|
+covered work in a country, or your recipient's use of the covered work
|
|
|
|
510
|
+in a country, would infringe one or more identifiable patents in that
|
|
|
|
511
|
+country that you have reason to believe are valid.
|
|
|
|
512
|
+
|
|
|
|
513
|
+ If, pursuant to or in connection with a single transaction or
|
|
|
|
514
|
+arrangement, you convey, or propagate by procuring conveyance of, a
|
|
|
|
515
|
+covered work, and grant a patent license to some of the parties
|
|
|
|
516
|
+receiving the covered work authorizing them to use, propagate, modify
|
|
|
|
517
|
+or convey a specific copy of the covered work, then the patent license
|
|
|
|
518
|
+you grant is automatically extended to all recipients of the covered
|
|
|
|
519
|
+work and works based on it.
|
|
|
|
520
|
+
|
|
|
|
521
|
+ A patent license is "discriminatory" if it does not include within
|
|
|
|
522
|
+the scope of its coverage, prohibits the exercise of, or is
|
|
|
|
523
|
+conditioned on the non-exercise of one or more of the rights that are
|
|
|
|
524
|
+specifically granted under this License. You may not convey a covered
|
|
|
|
525
|
+work if you are a party to an arrangement with a third party that is
|
|
|
|
526
|
+in the business of distributing software, under which you make payment
|
|
|
|
527
|
+to the third party based on the extent of your activity of conveying
|
|
|
|
528
|
+the work, and under which the third party grants, to any of the
|
|
|
|
529
|
+parties who would receive the covered work from you, a discriminatory
|
|
|
|
530
|
+patent license (a) in connection with copies of the covered work
|
|
|
|
531
|
+conveyed by you (or copies made from those copies), or (b) primarily
|
|
|
|
532
|
+for and in connection with specific products or compilations that
|
|
|
|
533
|
+contain the covered work, unless you entered into that arrangement,
|
|
|
|
534
|
+or that patent license was granted, prior to 28 March 2007.
|
|
|
|
535
|
+
|
|
|
|
536
|
+ Nothing in this License shall be construed as excluding or limiting
|
|
|
|
537
|
+any implied license or other defenses to infringement that may
|
|
|
|
538
|
+otherwise be available to you under applicable patent law.
|
|
|
|
539
|
+
|
|
|
|
540
|
+ 12. No Surrender of Others' Freedom.
|
|
|
|
541
|
+
|
|
|
|
542
|
+ If conditions are imposed on you (whether by court order, agreement or
|
|
|
|
543
|
+otherwise) that contradict the conditions of this License, they do not
|
|
|
|
544
|
+excuse you from the conditions of this License. If you cannot convey a
|
|
|
|
545
|
+covered work so as to satisfy simultaneously your obligations under this
|
|
|
|
546
|
+License and any other pertinent obligations, then as a consequence you may
|
|
|
|
547
|
+not convey it at all. For example, if you agree to terms that obligate you
|
|
|
|
548
|
+to collect a royalty for further conveying from those to whom you convey
|
|
|
|
549
|
+the Program, the only way you could satisfy both those terms and this
|
|
|
|
550
|
+License would be to refrain entirely from conveying the Program.
|
|
|
|
551
|
+
|
|
|
|
552
|
+ 13. Use with the GNU Affero General Public License.
|
|
|
|
553
|
+
|
|
|
|
554
|
+ Notwithstanding any other provision of this License, you have
|
|
|
|
555
|
+permission to link or combine any covered work with a work licensed
|
|
|
|
556
|
+under version 3 of the GNU Affero General Public License into a single
|
|
|
|
557
|
+combined work, and to convey the resulting work. The terms of this
|
|
|
|
558
|
+License will continue to apply to the part which is the covered work,
|
|
|
|
559
|
+but the special requirements of the GNU Affero General Public License,
|
|
|
|
560
|
+section 13, concerning interaction through a network will apply to the
|
|
|
|
561
|
+combination as such.
|
|
|
|
562
|
+
|
|
|
|
563
|
+ 14. Revised Versions of this License.
|
|
|
|
564
|
+
|
|
|
|
565
|
+ The Free Software Foundation may publish revised and/or new versions of
|
|
|
|
566
|
+the GNU General Public License from time to time. Such new versions will
|
|
|
|
567
|
+be similar in spirit to the present version, but may differ in detail to
|
|
|
|
568
|
+address new problems or concerns.
|
|
|
|
569
|
+
|
|
|
|
570
|
+ Each version is given a distinguishing version number. If the
|
|
|
|
571
|
+Program specifies that a certain numbered version of the GNU General
|
|
|
|
572
|
+Public License "or any later version" applies to it, you have the
|
|
|
|
573
|
+option of following the terms and conditions either of that numbered
|
|
|
|
574
|
+version or of any later version published by the Free Software
|
|
|
|
575
|
+Foundation. If the Program does not specify a version number of the
|
|
|
|
576
|
+GNU General Public License, you may choose any version ever published
|
|
|
|
577
|
+by the Free Software Foundation.
|
|
|
|
578
|
+
|
|
|
|
579
|
+ If the Program specifies that a proxy can decide which future
|
|
|
|
580
|
+versions of the GNU General Public License can be used, that proxy's
|
|
|
|
581
|
+public statement of acceptance of a version permanently authorizes you
|
|
|
|
582
|
+to choose that version for the Program.
|
|
|
|
583
|
+
|
|
|
|
584
|
+ Later license versions may give you additional or different
|
|
|
|
585
|
+permissions. However, no additional obligations are imposed on any
|
|
|
|
586
|
+author or copyright holder as a result of your choosing to follow a
|
|
|
|
587
|
+later version.
|
|
|
|
588
|
+
|
|
|
|
589
|
+ 15. Disclaimer of Warranty.
|
|
|
|
590
|
+
|
|
|
|
591
|
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
|
|
|
|
592
|
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
|
|
|
|
593
|
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
|
|
|
|
594
|
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
|
|
|
|
595
|
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
|
|
|
596
|
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
|
|
|
|
597
|
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
|
|
|
|
598
|
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
|
|
|
599
|
+
|
|
|
|
600
|
+ 16. Limitation of Liability.
|
|
|
|
601
|
+
|
|
|
|
602
|
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
|
|
|
603
|
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
|
|
|
|
604
|
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
|
|
|
|
605
|
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
|
|
|
|
606
|
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
|
|
|
|
607
|
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
|
|
|
|
608
|
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
|
|
|
|
609
|
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
|
|
|
|
610
|
+SUCH DAMAGES.
|
|
|
|
611
|
+
|
|
|
|
612
|
+ 17. Interpretation of Sections 15 and 16.
|
|
|
|
613
|
+
|
|
|
|
614
|
+ If the disclaimer of warranty and limitation of liability provided
|
|
|
|
615
|
+above cannot be given local legal effect according to their terms,
|
|
|
|
616
|
+reviewing courts shall apply local law that most closely approximates
|
|
|
|
617
|
+an absolute waiver of all civil liability in connection with the
|
|
|
|
618
|
+Program, unless a warranty or assumption of liability accompanies a
|
|
|
|
619
|
+copy of the Program in return for a fee.

|
+ How to Apply These Terms to Your New Programs
|
|
|
|
624
|
+
|
|
|
|
625
|
+ If you develop a new program, and you want it to be of the greatest
|
|
|
|
626
|
+possible use to the public, the best way to achieve this is to make it
|
|
|
|
627
|
+free software which everyone can redistribute and change under these terms.
|
|
|
|
628
|
+
|
|
|
|
629
|
+ To do so, attach the following notices to the program. It is safest
|
|
|
|
630
|
+to attach them to the start of each source file to most effectively
|
|
|
|
631
|
+state the exclusion of warranty; and each file should have at least
|
|
|
|
632
|
+the "copyright" line and a pointer to where the full notice is found.
|
|
|
|
633
|
