|
|
igor@10
|
5 Everyone is permitted to copy and distribute verbatim copies
|
|
igor@10
|
6 of this license document, but changing it is not allowed.

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

71 TERMS AND CONDITIONS
|
|
igor@10
|
72
|
|
igor@10
|
73 0. Definitions.
|
|
igor@10
|
74
|
|
igor@10
|
75 "This License" refers to version 3 of the GNU General Public License.
|
|
igor@10
|
76
|
|
igor@10
|
77 "Copyright" also means copyright-like laws that apply to other kinds of
|
|
igor@10
|
78 works, such as semiconductor masks.
|
|
igor@10
|
79
|
|
igor@10
|
80 "The Program" refers to any copyrightable work licensed under this
|
|
igor@10
|
81 License. Each licensee is addressed as "you". "Licensees" and
|
|
igor@10
|
82 "recipients" may be individuals or organizations.
|
|
igor@10
|
83
|
|
igor@10
|
84 To "modify" a work means to copy from or adapt all or part of the work
|
|
igor@10
|
85 in a fashion requiring copyright permission, other than the making of an
|
|
igor@10
|
86 exact copy. The resulting work is called a "modified version" of the
|
|
igor@10
|
87 earlier work or a work "based on" the earlier work.
|
|
igor@10
|
88
|
|
igor@10
|
89 A "covered work" means either the unmodified Program or a work based
|
|
igor@10
|
90 on the Program.
|
|
igor@10
|
91
|
|
igor@10
|
92 To "propagate" a work means to do anything with it that, without
|
|
igor@10
|
93 permission, would make you directly or secondarily liable for
|
|
igor@10
|
94 infringement under applicable copyright law, except executing it on a
|
|
igor@10
|
95 computer or modifying a private copy. Propagation includes copying,
|
|
igor@10
|
96 distribution (with or without modification), making available to the
|
|
igor@10
|
97 public, and in some countries other activities as well.
|
|
igor@10
|
98
|
|
igor@10
|
99 To "convey" a work means any kind of propagation that enables other
|
|
igor@10
|
100 parties to make or receive copies. Mere interaction with a user through
|
|
igor@10
|
101 a computer network, with no transfer of a copy, is not conveying.
|
|
igor@10
|
102
|
|
igor@10
|
103 An interactive user interface displays "Appropriate Legal Notices"
|
|
igor@10
|
104 to the extent that it includes a convenient and prominently visible
|
|
igor@10
|
105 feature that (1) displays an appropriate copyright notice, and (2)
|
|
igor@10
|
106 tells the user that there is no warranty for the work (except to the
|
|
igor@10
|
107 extent that warranties are provided), that licensees may convey the
|
|
igor@10
|
108 work under this License, and how to view a copy of this License. If
|
|
igor@10
|
109 the interface presents a list of user commands or options, such as a
|
|
igor@10
|
110 menu, a prominent item in the list meets this criterion.
|
|
igor@10
|
111
|
|
igor@10
|
112 1. Source Code.
|
|
igor@10
|
113
|
|
igor@10
|
114 The "source code" for a work means the preferred form of the work
|
|
igor@10
|
115 for making modifications to it. "Object code" means any non-source
|
|
igor@10
|
116 form of a work.
|
|
igor@10
|
117
|
|
igor@10
|
118 A "Standard Interface" means an interface that either is an official
|
|
igor@10
|
119 standard defined by a recognized standards body, or, in the case of
|
|
igor@10
|
120 interfaces specified for a particular programming language, one that
|
|
igor@10
|
121 is widely used among developers working in that language.
|
|
igor@10
|
122
|
|
igor@10
|
123 The "System Libraries" of an executable work include anything, other
|
|
igor@10
|
124 than the work as a whole, that (a) is included in the normal form of
|
|
igor@10
|
125 packaging a Major Component, but which is not part of that Major
|
|
igor@10
|
126 Component, and (b) serves only to enable use of the work with that
|
|
igor@10
|
127 Major Component, or to implement a Standard Interface for which an
|
|
igor@10
|
128 implementation is available to the public in source code form. A
|
|
igor@10
|
129 "Major Component", in this context, means a major essential component
|
|
igor@10
|
130 (kernel, window system, and so on) of the specific operating system
|
|
igor@10
|
131 (if any) on which the executable work runs, or a compiler used to
|
|
igor@10
|
132 produce the work, or an object code interpreter used to run it.
|
|
igor@10
|
133
|
|
igor@10
|
134 The "Corresponding Source" for a work in object code form means all
|
|
igor@10
|
135 the source code needed to generate, install, and (for an executable
|
|
igor@10
|
136 work) run the object code and to modify the work, including scripts to
|
|
igor@10
|
137 control those activities. However, it does not include the work's
|
|
igor@10
|
138 System Libraries, or general-purpose tools or generally available free
|
|
igor@10
|
139 programs which are used unmodified in performing those activities but
|
|
igor@10
|
140 which are not part of the work. For example, Corresponding Source
|
|
igor@10
|
141 includes interface definition files associated with source files for
|
|
igor@10
|
142 the work, and the source code for shared libraries and dynamically
|
|
igor@10
|
143 linked subprograms that the work is specifically designed to require,
|
|
igor@10
|
144 such as by intimate data communication or control flow between those
|
|
igor@10
|
145 subprograms and other parts of the work.
|
|
igor@10
|
146
|
|
igor@10
|
147 The Corresponding Source need not include anything that users
|
|
igor@10
|
148 can regenerate automatically from other parts of the Corresponding
|
|
igor@10
|
149 Source.
|
|
igor@10
|
150
|
|
igor@10
|
151 The Corresponding Source for a work in source code form is that
|
|
igor@10
|
152 same work.
|
|
igor@10
|
153
|
|
igor@10
|
154 2. Basic Permissions.
|
|
igor@10
|
155
|
|
igor@10
|
156 All rights granted under this License are granted for the term of
|
|
igor@10
|
157 copyright on the Program, and are irrevocable provided the stated
|
|
igor@10
|
158 conditions are met. This License explicitly affirms your unlimited
|
|
igor@10
|
159 permission to run the unmodified Program. The output from running a
|
|
igor@10
|
160 covered work is covered by this License only if the output, given its
|
|
igor@10
|
161 content, constitutes a covered work. This License acknowledges your
|
|
igor@10
|
162 rights of fair use or other equivalent, as provided by copyright law.
|
|
igor@10
|
163
|
|
igor@10
|
164 You may make, run and propagate covered works that you do not
|
|
igor@10
|
165 convey, without conditions so long as your license otherwise remains
|
|
igor@10
|
166 in force. You may convey covered works to others for the sole purpose
|
|
igor@10
|
167 of having them make modifications exclusively for you, or provide you
|
|
igor@10
|
168 with facilities for running those works, provided that you comply with
|
|
igor@10
|
169 the terms of this License in conveying all material for which you do
|
|
igor@10
|
170 not control copyright. Those thus making or running the covered works
|
|
igor@10
|
171 for you must do so exclusively on your behalf, under your direction
|
|
igor@10
|
172 and control, on terms that prohibit them from making any copies of
|
|
igor@10
|
173 your copyrighted material outside their relationship with you.
|
|
igor@10
|
174
|
|
igor@10
|
175 Conveying under any other circumstances is permitted solely under
|
|
igor@10
|
176 the conditions stated below. Sublicensing is not allowed; section 10
|
|
igor@10
|
177 makes it unnecessary.
|
|
igor@10
|
178
|
|
igor@10
|
179 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
|
igor@10
|
180
|
|
igor@10
|
181 No covered work shall be deemed part of an effective technological
|
|
igor@10
|
182 measure under any applicable law fulfilling obligations under article
|
|
igor@10
|
183 11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
|
igor@10
|
184 similar laws prohibiting or restricting circumvention of such
|
|
igor@10
|
185 measures.
|
|
igor@10
|
186
|
|
igor@10
|
187 When you convey a covered work, you waive any legal power to forbid
|
|
igor@10
|
188 circumvention of technological measures to the extent such circumvention
|
|
igor@10
|
189 is effected by exercising rights under this License with respect to
|
|
igor@10
|
190 the covered work, and you disclaim any intention to limit operation or
|
|
igor@10
|
191 modification of the work as a means of enforcing, against the work's
|
|
igor@10
|
192 users, your or third parties' legal rights to forbid circumvention of
|
|
igor@10
|
193 technological measures.
|
|
igor@10
|
194
|
|
igor@10
|
195 4. Conveying Verbatim Copies.
|
|
igor@10
|
196
|
|
igor@10
|
197 You may convey verbatim copies of the Program's source code as you
|
|
igor@10
|
198 receive it, in any medium, provided that you conspicuously and
|
|
igor@10
|
199 appropriately publish on each copy an appropriate copyright notice;
|
|
igor@10
|
200 keep intact all notices stating that this License and any
|
|
igor@10
|
201 non-permissive terms added in accord with section 7 apply to the code;
|
|
igor@10
|
202 keep intact all notices of the absence of any warranty; and give all
|
|
igor@10
|
203 recipients a copy of this License along with the Program.
|
|
igor@10
|
204
|
|
igor@10
|
205 You may charge any price or no price for each copy that you convey,
|
|
igor@10
|
206 and you may offer support or warranty protection for a fee.
|
|
igor@10
|
207
|
|
igor@10
|
208 5. Conveying Modified Source Versions.
|
|
igor@10
|
209
|
|
igor@10
|
210 You may convey a work based on the Program, or the modifications to
|
|
igor@10
|
211 produce it from the Program, in the form of source code under the
|
|
igor@10
|
212 terms of section 4, provided that you also meet all of these conditions:
|
|
igor@10
|
213
|
|
igor@10
|
214 a) The work must carry prominent notices stating that you modified
|
|
igor@10
|
215 it, and giving a relevant date.
|
|
igor@10
|
216
|
|
igor@10
|
217 b) The work must carry prominent notices stating that it is
|
|
igor@10
|
218 released under this License and any conditions added under section
|
|
igor@10
|
219 7. This requirement modifies the requirement in section 4 to
|
|
igor@10
|
220 "keep intact all notices".
|
|
igor@10
|
221
|
|
igor@10
|
222 c) You must license the entire work, as a whole, under this
|
|
igor@10
|
223 License to anyone who comes into possession of a copy. This
|
|
igor@10
|
224 License will therefore apply, along with any applicable section 7
|
|
igor@10
|
225 additional terms, to the whole of the work, and all its parts,
|
|
igor@10
|
226 regardless of how they are packaged. This License gives no
|
|
igor@10
|
227 permission to license the work in any other way, but it does not
|
|
igor@10
|
228 invalidate such permission if you have separately received it.
|
|
igor@10
|
229
|
|
igor@10
|
230 d) If the work has interactive user interfaces, each must display
|
|
igor@10
|
231 Appropriate Legal Notices; however, if the Program has interactive
|
|
igor@10
|
232 interfaces that do not display Appropriate Legal Notices, your
|
|
igor@10
|
233 work need not make them do so.
|
|
igor@10
|
234
|
|
igor@10
|
235 A compilation of a covered work with other separate and independent
|
|
igor@10
|
236 works, which are not by their nature extensions of the covered work,
|
|
igor@10
|
237 and which are not combined with it such as to form a larger program,
|
|
igor@10
|
238 in or on a volume of a storage or distribution medium, is called an
|
|
igor@10
|
239 "aggregate" if the compilation and its resulting copyright are not
|
|
igor@10
|
240 used to limit the access or legal rights of the compilation's users
|
|
igor@10
|
241 beyond what the individual works permit. Inclusion of a covered work
|
|
igor@10
|
242 in an aggregate does not cause this License to apply to the other
|
|
igor@10
|
243 parts of the aggregate.
|
|
igor@10
|
244
|
|
igor@10
|
245 6. Conveying Non-Source Forms.
|
|
igor@10
|
246
|
|
igor@10
|
247 You may convey a covered work in object code form under the terms
|
|
igor@10
|
248 of sections 4 and 5, provided that you also convey the
|
|
igor@10
|
249 machine-readable Corresponding Source under the terms of this License,
|
|
igor@10
|
250 in one of these ways:
|
|
igor@10
|
251
|
|
igor@10
|
252 a) Convey the object code in, or embodied in, a physical product
|
|
igor@10
|
253 (including a physical distribution medium), accompanied by the
|
|
igor@10
|
254 Corresponding Source fixed on a durable physical medium
|
|
igor@10
|
255 customarily used for software interchange.
|
|
igor@10
|
256
|
|
igor@10
|
257 b) Convey the object code in, or embodied in, a physical product
|
|
igor@10
|
258 (including a physical distribution medium), accompanied by a
|
|
igor@10
|
259 written offer, valid for at least three years and valid for as
|
|
igor@10
|
260 long as you offer spare parts or customer support for that product
|
|
igor@10
|
261 model, to give anyone who possesses the object code either (1) a
|
|
igor@10
|
262 copy of the Corresponding Source for all the software in the
|
|
igor@10
|
263 product that is covered by this License, on a durable physical
|
|
igor@10
|
264 medium customarily used for software interchange, for a price no
|
|
igor@10
|
265 more than your reasonable cost of physically performing this
|
|
igor@10
|
266 conveying of source, or (2) access to copy the
|
|
igor@10
|
267 Corresponding Source from a network server at no charge.
|
|
igor@10
|
268
|
|
igor@10
|
269 c) Convey individual copies of the object code with a copy of the
|
|
igor@10
|
270 written offer to provide the Corresponding Source. This
|
|
igor@10
|
271 alternative is allowed only occasionally and noncommercially, and
|
|
igor@10
|
272 only if you received the object code with such an offer, in accord
|
|
igor@10
|
273 with subsection 6b.
|
|
igor@10
|
274
|
|
igor@10
|
275 d) Convey the object code by offering access from a designated
|
|
igor@10
|
276 place (gratis or for a charge), and offer equivalent access to the
|
|
igor@10
|
277 Corresponding Source in the same way through the same place at no
|
|
igor@10
|
278 further charge. You need not require recipients to copy the
|
|
igor@10
|
279 Corresponding Source along with the object code. If the place to
|
|
igor@10
|
280 copy the object code is a network server, the Corresponding Source
|
|
igor@10
|
281 may be on a different server (operated by you or a third party)
|
|
igor@10
|
282 that supports equivalent copying facilities, provided you maintain
|
|
igor@10
|
283 clear directions next to the object code saying where to find the
|
|
igor@10
|
284 Corresponding Source. Regardless of what server hosts the
|
|
igor@10
|
285 Corresponding Source, you remain obligated to ensure that it is
|
|
igor@10
|
286 available for as long as needed to satisfy these requirements.
|
|
igor@10
|
287
|
|
igor@10
|
288 e) Convey the object code using peer-to-peer transmission, provided
|
|
igor@10
|
289 you inform other peers where the object code and Corresponding
|
|
igor@10
|
290 Source of the work are being offered to the general public at no
|
|
igor@10
|
291 charge under subsection 6d.
|
|
igor@10
|
292
|
|
igor@10
|
293 A separable portion of the object code, whose source code is excluded
|
|
igor@10
|
294 from the Corresponding Source as a System Library, need not be
|
|
igor@10
|
295 included in conveying the object code work.
|
|
igor@10
|
296
|
|
igor@10
|
297 A "User Product" is either (1) a "consumer product", which means any
|
|
igor@10
|
298 tangible personal property which is normally used for personal, family,
|
|
igor@10
|
299 or household purposes, or (2) anything designed or sold for incorporation
|
|
igor@10
|
300 into a dwelling. In determining whether a product is a consumer product,
|
|
igor@10
|
301 doubtful cases shall be resolved in favor of coverage. For a particular
|
|
igor@10
|
302 product received by a particular user, "normally used" refers to a
|
|
igor@10
|
303 typical or common use of that class of product, regardless of the status
|
|
igor@10
|
304 of the particular user or of the way in which the particular user
|
|
igor@10
|
305 actually uses, or expects or is expected to use, the product. A product
|
|
igor@10
|
306 is a consumer product regardless of whether the product has substantial
|
|
igor@10
|
307 commercial, industrial or non-consumer uses, unless such uses represent
|
|
igor@10
|
308 the only significant mode of use of the product.
|
|
igor@10
|
309
|
|
igor@10
|
310 "Installation Information" for a User Product means any methods,
|
|
igor@10
|
311 procedures, authorization keys, or other information required to install
|
|
igor@10
|
312 and execute modified versions of a covered work in that User Product from
|
|
igor@10
|
313 a modified version of its Corresponding Source. The information must
|
|
igor@10
|
314 suffice to ensure that the continued functioning of the modified object
|
|
igor@10
|
315 code is in no case prevented or interfered with solely because
|
|
igor@10
|
316 modification has been made.
|
|
igor@10
|
317
|
|
igor@10
|
318 If you convey an object code work under this section in, or with, or
|
|
igor@10
|
319 specifically for use in, a User Product, and the conveying occurs as
|
|
igor@10
|
320 part of a transaction in which the right of possession and use of the
|
|
igor@10
|
321 User Product is transferred to the recipient in perpetuity or for a
|
|
igor@10
|
322 fixed term (regardless of how the transaction is characterized), the
|
|
igor@10
|
323 Corresponding Source conveyed under this section must be accompanied
|
|
igor@10
|
324 by the Installation Information. But this requirement does not apply
|
|
igor@10
|
325 if neither you nor any third party retains the ability to install
|
|
igor@10
|
326 modified object code on the User Product (for example, the work has
|
|
igor@10
|
327 been installed in ROM).
|
|
igor@10
|
328
|
|
igor@10
|
329 The requirement to provide Installation Information does not include a
|
|
igor@10
|
330 requirement to continue to provide support service, warranty, or updates
|
|
igor@10
|
331 for a work that has been modified or installed by the recipient, or for
|
|
igor@10
|
332 the User Product in which it has been modified or installed. Access to a
|
|
igor@10
|
333 network may be denied when the modification itself materially and
|
|
igor@10
|
334 adversely affects the operation of the network or violates the rules and
|
|
igor@10
|
335 protocols for communication across the network.
|
|
igor@10
|
336
|
|
igor@10
|
337 Corresponding Source conveyed, and Installation Information provided,
|
|
igor@10
|
338 in accord with this section must be in a format that is publicly
|
|
igor@10
|
339 documented (and with an implementation available to the public in
|
|
igor@10
|
340 source code form), and must require no special password or key for
|
|
igor@10
|
341 unpacking, reading or copying.
|
|
igor@10
|
342
|
|
igor@10
|
343 7. Additional Terms.
|
|
igor@10
|
344
|
|
igor@10
|
345 "Additional permissions" are terms that supplement the terms of this
|
|
igor@10
|
346 License by making exceptions from one or more of its conditions.
|
|
igor@10
|
347 Additional permissions that are applicable to the entire Program shall
|
|
igor@10
|
348 be treated as though they were included in this License, to the extent
|
|
igor@10
|
349 that they are valid under applicable law. If additional permissions
|
|
igor@10
|
350 apply only to part of the Program, that part may be used separately
|
|
igor@10
|
351 under those permissions, but the entire Program remains governed by
|
|
igor@10
|
352 this License without regard to the additional permissions.
|
|
igor@10
|
353
|
|
igor@10
|
354 When you convey a copy of a covered work, you may at your option
|
|
igor@10
|
355 remove any additional permissions from that copy, or from any part of
|
|
igor@10
|
356 it. (Additional permissions may be written to require their own
|
|
igor@10
|
357 removal in certain cases when you modify the work.) You may place
|
|
igor@10
|
358 additional permissions on material, added by you to a covered work,
|
|
igor@10
|
359 for which you have or can give appropriate copyright permission.
|
|
igor@10
|
360
|
|
igor@10
|
361 Notwithstanding any other provision of this License, for material you
|
|
igor@10
|
362 add to a covered work, you may (if authorized by the copyright holders of
|
|
igor@10
|
363 that material) supplement the terms of this License with terms:
|
|
igor@10
|
364
|
|
igor@10
|
365 a) Disclaiming warranty or limiting liability differently from the
|
|
igor@10
|
366 terms of sections 15 and 16 of this License; or
|
|
igor@10
|
367
|
|
igor@10
|
368 b) Requiring preservation of specified reasonable legal notices or
|
|
igor@10
|
369 author attributions in that material or in the Appropriate Legal
|
|
igor@10
|
370 Notices displayed by works containing it; or
|
|
igor@10
|
371
|
|
igor@10
|
372 c) Prohibiting misrepresentation of the origin of that material, or
|
|
igor@10
|
373 requiring that modified versions of such material be marked in
|
|
igor@10
|
374 reasonable ways as different from the original version; or
|
|
igor@10
|
375
|
|
igor@10
|
376 d) Limiting the use for publicity purposes of names of licensors or
|
|
igor@10
|
377 authors of the material; or
|
|
igor@10
|
378
|
|
igor@10
|
379 e) Declining to grant rights under trademark law for use of some
|
|
igor@10
|
380 trade names, trademarks, or service marks; or
|
|
igor@10
|
381
|
|
igor@10
|
382 f) Requiring indemnification of licensors and authors of that
|
|
igor@10
|
383 material by anyone who conveys the material (or modified versions of
|
|
igor@10
|
384 it) with contractual assumptions of liability to the recipient, for
|
|
igor@10
|
385 any liability that these contractual assumptions directly impose on
|
|
igor@10
|
386 those licensors and authors.
|
|
igor@10
|
387
|
|
igor@10
|
388 All other non-permissive additional terms are considered "further
|
|
igor@10
|
389 restrictions" within the meaning of section 10. If the Program as you
|
|
igor@10
|
390 received it, or any part of it, contains a notice stating that it is
|
|
igor@10
|
391 governed by this License along with a term that is a further
|
|
igor@10
|
392 restriction, you may remove that term. If a license document contains
|
|
igor@10
|
393 a further restriction but permits relicensing or conveying under this
|
|
igor@10
|
394 License, you may add to a covered work material governed by the terms
|
|
igor@10
|
395 of that license document, provided that the further restriction does
|
|
igor@10
|
396 not survive such relicensing or conveying.
|
|
igor@10
|
397
|
|
igor@10
|
398 If you add terms to a covered work in accord with this section, you
|
|
igor@10
|
399 must place, in the relevant source files, a statement of the
|
|
igor@10
|
400 additional terms that apply to those files, or a notice indicating
|
|
igor@10
|
401 where to find the applicable terms.
|
|
igor@10
|
402
|
|
igor@10
|
403 Additional terms, permissive or non-permissive, may be stated in the
|
|
igor@10
|
404 form of a separately written license, or stated as exceptions;
|
|
igor@10
|
405 the above requirements apply either way.
|
|
igor@10
|
406
|
|
igor@10
|
407 8. Termination.
|
|
igor@10
|
408
|
|
igor@10
|
409 You may not propagate or modify a covered work except as expressly
|
|
igor@10
|
410 provided under this License. Any attempt otherwise to propagate or
|
|
igor@10
|
411 modify it is void, and will automatically terminate your rights under
|
|
igor@10
|
412 this License (including any patent licenses granted under the third
|
|
igor@10
|
413 paragraph of section 11).
|
|
igor@10
|
414
|
|
igor@10
|
415 However, if you cease all violation of this License, then your
|
|
igor@10
|
416 license from a particular copyright holder is reinstated (a)
|
|
igor@10
|
417 provisionally, unless and until the copyright holder explicitly and
|
|
igor@10
|
418 finally terminates your license, and (b) permanently, if the copyright
|
|
igor@10
|
419 holder fails to notify you of the violation by some reasonable means
|
|
igor@10
|
420 prior to 60 days after the cessation.
|
|
igor@10
|
421
|
|
igor@10
|
422 Moreover, your license from a particular copyright holder is
|
|
igor@10
|
423 reinstated permanently if the copyright holder notifies you of the
|
|
igor@10
|
424 violation by some reasonable means, this is the first time you have
|
|
igor@10
|
425 received notice of violation of this License (for any work) from that
|
|
igor@10
|
426 copyright holder, and you cure the violation prior to 30 days after
|
|
igor@10
|
427 your receipt of the notice.
|
|
igor@10
|
428
|
|
igor@10
|
429 Termination of your rights under this section does not terminate the
|
|
igor@10
|
430 licenses of parties who have received copies or rights from you under
|
|
igor@10
|
431 this License. If your rights have been terminated and not permanently
|
|
igor@10
|
432 reinstated, you do not qualify to receive new licenses for the same
|
|
igor@10
|
433 material under section 10.
|
|
igor@10
|
434
|
|
igor@10
|
435 9. Acceptance Not Required for Having Copies.
|
|
igor@10
|
436
|
|
igor@10
|
437 You are not required to accept this License in order to receive or
|
|
igor@10
|
438 run a copy of the Program. Ancillary propagation of a covered work
|
|
igor@10
|
439 occurring solely as a consequence of using peer-to-peer transmission
|
|
igor@10
|
440 to receive a copy likewise does not require acceptance. However,
|
|
igor@10
|
441 nothing other than this License grants you permission to propagate or
|
|
igor@10
|
442 modify any covered work. These actions infringe copyright if you do
|
|
igor@10
|
443 not accept this License. Therefore, by modifying or propagating a
|
|
igor@10
|
444 covered work, you indicate your acceptance of this License to do so.
|
|
igor@10
|
445
|
|
igor@10
|
446 10. Automatic Licensing of Downstream Recipients.
|
|
igor@10
|
447
|
|
igor@10
|
448 Each time you convey a covered work, the recipient automatically
|
|
igor@10
|
449 receives a license from the original licensors, to run, modify and
|
|
igor@10
|
450 propagate that work, subject to this License. You are not responsible
|
|
igor@10
|
451 for enforcing compliance by third parties with this License.
|
|
igor@10
|
452
|
|
igor@10
|
453 An "entity transaction" is a transaction transferring control of an
|
|
igor@10
|
454 organization, or substantially all assets of one, or subdividing an
|
|
igor@10
|
455 organization, or merging organizations. If propagation of a covered
|
|
igor@10
|
456 work results from an entity transaction, each party to that
|
|
igor@10
|
457 transaction who receives a copy of the work also receives whatever
|
|
igor@10
|
458 licenses to the work the party's predecessor in interest had or could
|
|
igor@10
|
459 give under the previous paragraph, plus a right to possession of the
|
|
igor@10
|
460 Corresponding Source of the work from the predecessor in interest, if
|
|
igor@10
|
461 the predecessor has it or can get it with reasonable efforts.
|
|
igor@10
|
462
|
|
igor@10
|
463 You may not impose any further restrictions on the exercise of the
|
|
igor@10
|
464 rights granted or affirmed under this License. For example, you may
|
|
igor@10
|
465 not impose a license fee, royalty, or other charge for exercise of
|
|
igor@10
|
466 rights granted under this License, and you may not initiate litigation
|
|
igor@10
|
467 (including a cross-claim or counterclaim in a lawsuit) alleging that
|
|
igor@10
|
468 any patent claim is infringed by making, using, selling, offering for
|
|
igor@10
|
469 sale, or importing the Program or any portion of it.
|
|
igor@10
|
470
|
|
igor@10
|
471 11. Patents.
|
|
igor@10
|
472
|
|
igor@10
|
473 A "contributor" is a copyright holder who authorizes use under this
|
|
igor@10
|
474 License of the Program or a work on which the Program is based. The
|
|
igor@10
|
475 work thus licensed is called the contributor's "contributor version".
|
|
igor@10
|
476
|
|
igor@10
|
477 A contributor's "essential patent claims" are all patent claims
|
|
igor@10
|
478 owned or controlled by the contributor, whether already acquired or
|
|
igor@10
|
479 hereafter acquired, that would be infringed by some manner, permitted
|
|
igor@10
|
480 by this License, of making, using, or selling its contributor version,
|
|
igor@10
|
481 but do not include claims that would be infringed only as a
|
|
igor@10
|
482 consequence of further modification of the contributor version. For
|
|
igor@10
|
483 purposes of this definition, "control" includes the right to grant
|
|
igor@10
|
484 patent sublicenses in a manner consistent with the requirements of
|
|
igor@10
|
485 this License.
|
|
igor@10
|
486
|
|
igor@10
|
487 Each contributor grants you a non-exclusive, worldwide, royalty-free
|
|
igor@10
|
488 patent license under the contributor's essential patent claims, to
|
|
igor@10
|
489 make, use, sell, offer for sale, import and otherwise run, modify and
|
|
igor@10
|
490 propagate the contents of its contributor version.
|
|
igor@10
|
491
|
|
igor@10
|
492 In the following three paragraphs, a "patent license" is any express
|
|
igor@10
|
493 agreement or commitment, however denominated, not to enforce a patent
|
|
igor@10
|
494 (such as an express permission to practice a patent or covenant not to
|
|
igor@10
|
495 sue for patent infringement). To "grant" such a patent license to a
|
|
igor@10
|
496 party means to make such an agreement or commitment not to enforce a
|
|
igor@10
|
497 patent against the party.
|
|
igor@10
|
498
|
|
igor@10
|
499 If you convey a covered work, knowingly relying on a patent license,
|
|
igor@10
|
500 and the Corresponding Source of the work is not available for anyone
|
|
igor@10
|
501 to copy, free of charge and under the terms of this License, through a
|
|
igor@10
|
502 publicly available network server or other readily accessible means,
|
|
igor@10
|
503 then you must either (1) cause the Corresponding Source to be so
|
|
igor@10
|
504 available, or (2) arrange to deprive yourself of the benefit of the
|
|
igor@10
|
505 patent license for this particular work, or (3) arrange, in a manner
|
|
igor@10
|
506 consistent with the requirements of this License, to extend the patent
|
|
igor@10
|
507 license to downstream recipients. "Knowingly relying" means you have
|
|
igor@10
|
508 actual knowledge that, but for the patent license, your conveying the
|
|
igor@10
|
509 covered work in a country, or your recipient's use of the covered work
|
|
igor@10
|
510 in a country, would infringe one or more identifiable patents in that
|
|
igor@10
|
511 country that you have reason to believe are valid.
|
|
igor@10
|
512
|
|
igor@10
|
513 If, pursuant to or in connection with a single transaction or
|
|
igor@10
|
514 arrangement, you convey, or propagate by procuring conveyance of, a
|
|
igor@10
|
515 covered work, and grant a patent license to some of the parties
|
|
igor@10
|
516 receiving the covered work authorizing them to use, propagate, modify
|
|
igor@10
|
517 or convey a specific copy of the covered work, then the patent license
|
|
igor@10
|
518 you grant is automatically extended to all recipients of the covered
|
|
igor@10
|
519 work and works based on it.
|
|
igor@10
|
520
|
|
igor@10
|
521 A patent license is "discriminatory" if it does not include within
|
|
igor@10
|
522 the scope of its coverage, prohibits the exercise of, or is
|
|
igor@10
|
523 conditioned on the non-exercise of one or more of the rights that are
|
|
igor@10
|
524 specifically granted under this License. You may not convey a covered
|
|
igor@10
|
525 work if you are a party to an arrangement with a third party that is
|
|
igor@10
|
526 in the business of distributing software, under which you make payment
|
|
igor@10
|
527 to the third party based on the extent of your activity of conveying
|
|
igor@10
|
528 the work, and under which the third party grants, to any of the
|
|
igor@10
|
529 parties who would receive the covered work from you, a discriminatory
|
|
igor@10
|
530 patent license (a) in connection with copies of the covered work
|
|
igor@10
|
531 conveyed by you (or copies made from those copies), or (b) primarily
|
|
igor@10
|
532 for and in connection with specific products or compilations that
|
|
igor@10
|
533 contain the covered work, unless you entered into that arrangement,
|
|
igor@10
|
534 or that patent license was granted, prior to 28 March 2007.
|
|
igor@10
|
535
|
|
igor@10
|
536 Nothing in this License shall be construed as excluding or limiting
|
|
igor@10
|
537 any implied license or other defenses to infringement that may
|
|
igor@10
|
538 otherwise be available to you under applicable patent law.
|
|
igor@10
|
539
|
|
igor@10
|
540 12. No Surrender of Others' Freedom.
|
|
igor@10
|
541
|
|
igor@10
|
542 If conditions are imposed on you (whether by court order, agreement or
|
|
igor@10
|
543 otherwise) that contradict the conditions of this License, they do not
|
|
igor@10
|
544 excuse you from the conditions of this License. If you cannot convey a
|
|
igor@10
|
545 covered work so as to satisfy simultaneously your obligations under this
|
|
igor@10
|
546 License and any other pertinent obligations, then as a consequence you may
|
|
igor@10
|
547 not convey it at all. For example, if you agree to terms that obligate you
|
|
igor@10
|
548 to collect a royalty for further conveying from those to whom you convey
|
|
igor@10
|
549 the Program, the only way you could satisfy both those terms and this
|
|
igor@10
|
550 License would be to refrain entirely from conveying the Program.
|
|
igor@10
|
551
|
|
igor@10
|
552 13. Use with the GNU Affero General Public License.
|
|
igor@10
|
553
|
|
igor@10
|
554 Notwithstanding any other provision of this License, you have
|
|
igor@10
|
555 permission to link or combine any covered work with a work licensed
|
|
igor@10
|
556 under version 3 of the GNU Affero General Public License into a single
|
|
igor@10
|
557 combined work, and to convey the resulting work. The terms of this
|
|
igor@10
|
558 License will continue to apply to the part which is the covered work,
|
|
igor@10
|
559 but the special requirements of the GNU Affero General Public License,
|
|
igor@10
|
560 section 13, concerning interaction through a network will apply to the
|
|
igor@10
|
561 combination as such.
|
|
igor@10
|
562
|
|
igor@10
|
563 14. Revised Versions of this License.
|
|
igor@10
|
564
|
|
igor@10
|
565 The Free Software Foundation may publish revised and/or new versions of
|
|
igor@10
|
566 the GNU General Public License from time to time. Such new versions will
|
|
igor@10
|
567 be similar in spirit to the present version, but may differ in detail to
|
|
igor@10
|
568 address new problems or concerns.
|
|
igor@10
|
569
|
|
igor@10
|
570 Each version is given a distinguishing version number. If the
|
|
igor@10
|
571 Program specifies that a certain numbered version of the GNU General
|
|
igor@10
|
572 Public License "or any later version" applies to it, you have the
|
|
igor@10
|
573 option of following the terms and conditions either of that numbered
|
|
igor@10
|
574 version or of any later version published by the Free Software
|
|
igor@10
|
575 Foundation. If the Program does not specify a version number of the
|
|
igor@10
|
576 GNU General Public License, you may choose any version ever published
|
|
igor@10
|
577 by the Free Software Foundation.
|
|
igor@10
|
578
|
|
igor@10
|
579 If the Program specifies that a proxy can decide which future
|
|
igor@10
|
580 versions of the GNU General Public License can be used, that proxy's
|
|
igor@10
|
581 public statement of acceptance of a version permanently authorizes you
|
|
igor@10
|
582 to choose that version for the Program.
|
|
igor@10
|
583
|
|
igor@10
|
584 Later license versions may give you additional or different
|
|
igor@10
|
585 permissions. However, no additional obligations are imposed on any
|
|
igor@10
|
586 author or copyright holder as a result of your choosing to follow a
|
|
igor@10
|
587 later version.
|
|
igor@10
|
588
|
|
igor@10
|
589 15. Disclaimer of Warranty.
|
|
igor@10
|
590
|
|
igor@10
|
591 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
|
|
igor@10
|
592 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
|
|
igor@10
|
593 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
|
|
igor@10
|
594 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
|
|
igor@10
|
595 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
|
igor@10
|
596 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
|
|
igor@10
|
597 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
|
|
igor@10
|
598 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
|
igor@10
|
599
|
|
igor@10
|
600 16. Limitation of Liability.
|
|
igor@10
|
601
|
|
igor@10
|
602 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
|
igor@10
|
603 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
|
|
igor@10
|
604 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
|
|
igor@10
|
605 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
|
|
igor@10
|
606 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
|
|
igor@10
|
607 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
|
|
igor@10
|
608 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
|
|
igor@10
|
609 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
|
|
igor@10
|
610 SUCH DAMAGES.

igor@10

612 17. Interpretation of Sections 15 and 16.
|
|
igor@10
|
613
|
|
igor@10
|
614 If the disclaimer of warranty and limitation of liability provided
|
|
igor@10
|
615 above cannot be given local legal effect according to their terms,
|
|
igor@10
|
616 reviewing courts shall apply local law that most closely approximates
|
|
igor@10
|
617 an absolute waiver of all civil liability in connection with the
|
|
igor@10
|
618 Program, unless a warranty or assumption of liability accompanies a
|
|
igor@10
|
619 copy of the Program in return for a fee.

|
623 How to Apply These Terms to Your New Programs
|
|
igor@10
|
624
|
|
igor@10
|
625 If you develop a new program, and you want it to be of the greatest
|
|
igor@10
|
626 possible use to the public, the best way to achieve this is to make it
|
|
igor@10
|
627 free software which everyone can redistribute and change under these terms.
|
|
igor@10
|
628
|
|
igor@10
|
629 To do so, attach the following notices to the program. It is safest
|
|
igor@10
|
630 to attach them to the start of each source file to most effectively
|
|
igor@10
|
631 state the exclusion of warranty; and each file should have at least
|
|
igor@10
|
632 the "copyright" line and a pointer to where the full notice is found.
|
|
igor@10
|
633
|
|
igor@10
|
634 <one line to give the program's name and a brief idea of what it does.>

|

642 This program is distributed in the hope that it will be useful,
|
|
igor@10

644 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the

645 GNU General Public License for more details.
|
|
igor@10

646
|
|
igor@10
|
647 You should have received a copy of the GNU General Public License
|
|
igor@10
|
648 along with this program. If not, see <http://www.gnu.org/licenses/>.
|
|
igor@10
|
649
|
|
igor@10
|
650 Also add information on how to contact you by electronic and paper mail.
|
|
igor@10
|
651
|
|
igor@10
|
652 If the program does terminal interaction, make it output a short
|
|
igor@10
|
653 notice like this when it starts in an interactive mode:
|
|
igor@10
|
654
|
|
igor@10
|
655 <program> Copyright (C) <year> <name of author>

656 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
|
igor@10
|
657 This is free software, and you are welcome to redistribute it
|

|
658 under certain conditions; type `show c' for details.
|
|
igor@10
|
659
|
|
igor@10
|
660 The hypothetical commands `show w' and `show c' should show the appropriate
|
|
igor@10
|
661 parts of the General Public License. Of course, your program's commands
|
|
igor@10
|
662 might be different; for a GUI interface, you would use an "about box".
|
|
igor@10
|
663
|
|
igor@10
|
664 You should also get your employer (if you work as a programmer) or school,
|
|
igor@10
|
665 if any, to sign a "copyright disclaimer" for the program, if necessary.

669 The GNU General Public License does not permit incorporating your program

igor@10

672 the library. If this is what you want to do, use the GNU Lesser General
