Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> |

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

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. |
| 70 |
|
| 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 |
| 489 |
make, use, sell, offer for sale, import and otherwise run, modify and |
| 490 |
propagate the contents of its contributor version. |
| 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. |
| 620 |
|
| 621 |
END OF TERMS AND CONDITIONS |
| 622 |
|
| 623 |
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 |
|
| 634 |
<one line to give the program's name and a brief idea of what it does.> |
| 635 |
Copyright (C) <year> <name of author> |
| 636 |
|
| 637 |
This program is free software: you can redistribute it and/or modify |
| 638 |
it under the terms of the GNU General Public License as published by |
| 639 |
the Free Software Foundation, either version 3 of the License, or |
| 640 |
(at your option) any later version. |
| 641 |
|
| 642 |
This program is distributed in the hope that it will be useful, |
| 643 |
but WITHOUT ANY WARRANTY; without even the implied warranty of |
| 644 |
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the |
| 645 |
GNU General Public License for more details. |
| 646 |
|
| 647 |
You should have received a copy of the GNU General Public License |
| 648 |
along with this program. If not, see <http://www.gnu.org/licenses/>. |
| 649 |
|
| 650 |
Also add information on how to contact you by electronic and paper mail. |
| 651 |
|
| 652 |
If the program does terminal interaction, make it output a short |
| 653 |
notice like this when it starts in an interactive mode: |
| 654 |
|
| 655 |
<program> Copyright (C) <year> <name of author> |
| 656 |
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. |
| 657 |
This is free software, and you are welcome to redistribute it |
| 658 |
under certain conditions; type `show c' for details. |
| 659 |
|
| 660 |
The hypothetical commands `show w' and `show c' should show the appropriate |
| 661 |
parts of the General Public License. Of course, your program's commands |
| 662 |
might be different; for a GUI interface, you would use an "about box". |
| 663 |
|
| 664 |
You should also get your employer (if you work as a programmer) or school, |
| 665 |
if any, to sign a "copyright disclaimer" for the program, if necessary. |
| 666 |

| 668 |
|
| 669 |
The GNU General Public License does not permit incorporating your program |
| 670 |
into proprietary programs. If your program is a subroutine library, you |
| 671 |
may consider it more useful to permit linking proprietary applications with |
| 672 |
the library. If this is what you want to do, use the GNU Lesser General |
| 673 |
Public License instead of this License. But first, please read |
| 674 |
