By contrast, 0026 the GNU General Public License is intended to guarantee your freedom to 0027 share and change all versions of a program--to make sure it remains free 0028 software for all its users. We, the Free Software Foundation, use the 0029 GNU General Public License for most of our software; it applies also to 0030 any other work released this way by its authors. You can apply it to 0031 your programs, too.</p> 0032 0033 <p>When we speak of free software, we are referring to freedom, not 0034 price. Our General Public Licenses are designed to make sure that you 0035 have the freedom to distribute copies of free software (and charge for 0036 them if you wish), that you receive source code or can get it if you 0037 want it, that you can change the software or use pieces of it in new 0038 free programs, and that you know you can do these things.</p> 0039 0040 <p>To protect your rights, we need to prevent others from denying you 0041 these rights or asking you to surrender the rights. Therefore, you have 0042 certain responsibilities if you distribute copies of the software, or if 0043 you modify it: responsibilities to respect the freedom of others.</p> 0044 0045 <p>For example, if you distribute copies of such a program, whether 0046 gratis or for a fee, you must pass on to the recipients the same 0047 freedoms that you received. You must make sure that they, too, receive 0048 or can get the source code. And you must show them these terms so they 0049 know their rights.</p> 0050 0051 <p>Developers that use the GNU GPL protect your rights with two steps: 0052 (1) assert copyright on the software, and (2) offer you this License 0053 giving you legal permission to copy, distribute and/or modify it.</p> 0054 0055 <p>For the developers' and authors' protection, the GPL clearly explains 0056 that there is no warranty for this free software. For both users' and 0057 authors' sake, the GPL requires that modified versions be marked as 0058 changed, so that their problems will not be attributed erroneously to 0059 authors of previous versions.</p> 0060 0061 <p>Some devices are designed to deny users access to install or run 0062 modified versions of the software inside them, although the manufacturer 0063 can do so. This is fundamentally incompatible with the aim of 0064 protecting users' freedom to change the software. The systematic 0065 pattern of such abuse occurs in the area of products for individuals to 0066 use, which is precisely where it is most unacceptable. Therefore, we 0067 have designed this version of the GPL to prohibit the practice for those 0068 products. If such problems arise substantially in other domains, we 0069 stand ready to extend this provision to those domains in future versions 0070 of the GPL, as needed to protect the freedom of users.</p> 0071 0072 <p>Finally, every program is threatened constantly by software patents. 0073 States should not allow patents to restrict development and use of 0074 software on general-purpose computers, but in those that do, we wish to 0075 avoid the special danger that patents applied to a free program could 0076 make it effectively proprietary. To prevent this, the GPL assures that 0077 patents cannot be used to render the program non-free.</p> 0078 0079 <p>The precise terms and conditions for copying, distribution and 0080 modification follow.</p> 0081 0082 <h3><a name="terms"></a>TERMS AND CONDITIONS</h3> 0083 0084 <h4><a name="section0"></a>0. Definitions.</h4> 0085 0086 <p>“This License” refers to version 3 of the GNU General Public License.</p> 0087 0088 <p>“Copyright” also means copyright-like laws that apply to other kinds of 0089 works, such as semiconductor masks.</p> 0090 0091 <p>“The Program” refers to any copyrightable work licensed under this 0092 License. Each licensee is addressed as “you”. “Licensees” and 0093 “recipients” may be individuals or organizations.</p> 0094 0095 <p>To “modify” a work means to copy from or adapt all or part of the work 0096 in a fashion requiring copyright permission, other than the making of an 0097 exact copy. The resulting work is called a “modified version” of the 0098 earlier work or a work “based on” the earlier work.</p> 0099 0100 <p>A “covered work” means either the unmodified Program or a work based 0101 on the Program.</p> 0102 0103 <p>To “propagate” a work means to do anything with it that, without 0104 permission, would make you directly or secondarily liable for 0105 infringement under applicable copyright law, except executing it on a 0106 computer or modifying a private copy. Propagation includes copying, 0107 distribution (with or without modification), making available to the 0108 public, and in some countries other activities as well.</p> 0109 0110 <p>To “convey” a work means any kind of propagation that enables other 0111 parties to make or receive copies. Mere interaction with a user through 0112 a computer network, with no transfer of a copy, is not conveying.</p> 0113 0114 <p>An interactive user interface displays “Appropriate Legal Notices” 0115 to the extent that it includes a convenient and prominently visible 0116 feature that (1) displays an appropriate copyright notice, and (2) 0117 tells the user that there is no warranty for the work (except to the 0118 extent that warranties are provided), that licensees may convey the 0119 work under this License, and how to view a copy of this License. If 0120 the interface presents a list of user commands or options, such as a 0121 menu, a prominent item in the list meets this criterion.</p> 0122 0123 <h4><a name="section1"></a>1. Source Code.</h4> 0124 0125 <p>The “source code” for a work means the preferred form of the work 0126 for making modifications to it. “Object code” means any non-source 0127 form of a work.</p> 0128 0129 <p>A “Standard Interface” means an interface that either is an official 0130 standard defined by a recognized standards body, or, in the case of 0131 interfaces specified for a particular programming language, one that 0132 is widely used among developers working in that language.</p> 0133 0134 <p>The “System Libraries” of an executable work include anything, other 0135 than the work as a whole, that (a) is included in the normal form of 0136 packaging a Major Component, but which is not part of that Major 0137 Component, and (b) serves only to enable use of the work with that 0138 Major Component, or to implement a Standard Interface for which an 0139 implementation is available to the public in source code form. A 0140 “Major Component”, in this context, means a major essential component 0141 (kernel, window system, and so on) of the specific operating system 0142 (if any) on which the executable work runs, or a compiler used to 0143 produce the work, or an object code interpreter used to run it.</p> 0144 0145 <p>The “Corresponding Source” for a work in object code form means all 0146 the source code needed to generate, install, and (for an executable 0147 work) run the object code and to modify the work, including scripts to 0148 control those activities. However, it does not include the work's 0149 System Libraries, or general-purpose tools or generally available free 0150 programs which are used unmodified in performing those activities but 0151 which are not part of the work. For example, Corresponding Source 0152 includes interface definition files associated with source files for 0153 the work, and the source code for shared libraries and dynamically 0154 linked subprograms that the work is specifically designed to require, 0155 such as by intimate data communication or control flow between those 0156 subprograms and other parts of the work.</p> 0157 0158 <p>The Corresponding Source need not include anything that users 0159 can regenerate automatically from other parts of the Corresponding 0160 Source.</p> 0161 0162 <p>The Corresponding Source for a work in source code form is that 0163 same work.</p> 0164 0165 <h4><a name="section2"></a>2. Basic Permissions.</h4> 0166 0167 <p>All rights granted under this License are granted for the term of 0168 copyright on the Program, and are irrevocable provided the stated 0169 conditions are met. This License explicitly affirms your unlimited 0170 permission to run the unmodified Program. The output from running a 0171 covered work is covered by this License only if the output, given its 0172 content, constitutes a covered work. This License acknowledges your 0173 rights of fair use or other equivalent, as provided by copyright law.</p> 0174 0175 <p>You may make, run and propagate covered works that you do not 0176 convey, without conditions so long as your license otherwise remains 0177 in force. You may convey covered works to others for the sole purpose 0178 of having them make modifications exclusively for you, or provide you 0179 with facilities for running those works, provided that you comply with 0180 the terms of this License in conveying all material for which you do 0181 not control copyright. Those thus making or running the covered works 0182 for you must do so exclusively on your behalf, under your direction 0183 and control, on terms that prohibit them from making any copies of 0184 your copyrighted material outside their relationship with you.</p> 0185 0186 <p>Conveying under any other circumstances is permitted solely under 0187 the conditions stated below. Sublicensing is not allowed; section 10 0188 makes it unnecessary.</p> 0189 0190 <h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4> 0191 0192 <p>No covered work shall be deemed part of an effective technological 0193 measure under any applicable law fulfilling obligations under article 0194 11 of the WIPO copyright treaty adopted on 20 December 1996, or 0195 similar laws prohibiting or restricting circumvention of such 0196 measures.</p> 0197 0198 <p>When you convey a covered work, you waive any legal power to forbid 0199 circumvention of technological measures to the extent such circumvention 0200 is effected by exercising rights under this License with respect to 0201 the covered work, and you disclaim any intention to limit operation or 0202 modification of the work as a means of enforcing, against the work's 0203 users, your or third parties' legal rights to forbid circumvention of 0204 technological measures.</p> 0205 0206 <h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4> 0207 0208 <p>You may convey verbatim copies of the Program's source code as you 0209 receive it, in any medium, provided that you conspicuously and 0210 appropriately publish on each copy an appropriate copyright notice; 0211 keep intact all notices stating that this License and any 0212 non-permissive terms added in accord with section 7 apply to the code; 0213 keep intact all notices of the absence of any warranty; and give all 0214 recipients a copy of this License along with the Program.</p> 0215 0216 <p>You may charge any price or no price for each copy that you convey, 0217 and you may offer support or warranty protection for a fee.</p> 0218 0219 <h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4> 0220 0221 <p>You may convey a work based on the Program, or the modifications to 0222 produce it from the Program, in the form of source code under the 0223 terms of section 4, provided that you also meet all of these conditions:</p> 0224 0225 <ul> 0226 <li>a) The work must carry prominent notices stating that you modified 0227 it, and giving a relevant date.</li> 0228 0229 <li>b) The work must carry prominent notices stating that it is 0230 released under this License and any conditions added under section 0231 7. This requirement modifies the requirement in section 4 to 0232 “keep intact all notices”.</li> 0233 0234 <li>c) You must license the entire work, as a whole, under this 0235 License to anyone who comes into possession of a copy. This 0236 License will therefore apply, along with any applicable section 7 0237 additional terms, to the whole of the work, and all its parts, 0238 regardless of how they are packaged. This License gives no 0239 permission to license the work in any other way, but it does not 0240 invalidate such permission if you have separately received it.</li> 0241 0242 <li>d) If the work has interactive user interfaces, each must display 0243 Appropriate Legal Notices; however, if the Program has interactive 0244 interfaces that do not display Appropriate Legal Notices, your 0245 work need not make them do so.</li> 0246 </ul> 0247 0248 <p>A compilation of a covered work with other separate and independent 0249 works, which are not by their nature extensions of the covered work, 0250 and which are not combined with it such as to form a larger program, 0251 in or on a volume of a storage or distribution medium, is called an 0252 “aggregate” if the compilation and its resulting copyright are not 0253 used to limit the access or legal rights of the compilation's users 0254 beyond what the individual works permit. Inclusion of a covered work 0255 in an aggregate does not cause this License to apply to the other 0256 parts of the aggregate.</p> 0257 0258 <h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4> 0259 0260 <p>You may convey a covered work in object code form under the terms 0261 of sections 4 and 5, provided that you also convey the 0262 machine-readable Corresponding Source under the terms of this License, 0263 in one of these ways:</p> 0264 0265 <ul> 0266 <li>a) Convey the object code in, or embodied in, a physical product 0267 (including a physical distribution medium), accompanied by the 0268 Corresponding Source fixed on a durable physical medium 0269 customarily used for software interchange.</li> 0270 0271 <li>b) Convey the object code in, or embodied in, a physical product 0272 (including a physical distribution medium), accompanied by a 0273 written offer, valid for at least three years and valid for as 0274 long as you offer spare parts or customer support for that product 0275 model, to give anyone who possesses the object code either (1) a 0276 copy of the Corresponding Source for all the software in the 0277 product that is covered by this License, on a durable physical 0278 medium customarily used for software interchange, for a price no 0279 more than your reasonable cost of physically performing this 0280 conveying of source, or (2) access to copy the 0281 Corresponding Source from a network server at no charge.</li> 0282 0283 <li>c) Convey individual copies of the object code with a copy of the 0284 written offer to provide the Corresponding Source. This 0285 alternative is allowed only occasionally and noncommercially, and 0286 only if you received the object code with such an offer, in accord 0287 with subsection 6b.</li> 0288 0289 <li>d) Convey the object code by offering access from a designated 0290 place (gratis or for a charge), and offer equivalent access to the 0291 Corresponding Source in the same way through the same place at no 0292 further charge. You need not require recipients to copy the 0293 Corresponding Source along with the object code. If the place to 0294 copy the object code is a network server, the Corresponding Source 0295 may be on a different server (operated by you or a third party) 0296 that supports equivalent copying facilities, provided you maintain 0297 clear directions next to the object code saying where to find the 0298 Corresponding Source. Regardless of what server hosts the 0299 Corresponding Source, you remain obligated to ensure that it is 0300 available for as long as needed to satisfy these requirements.</li> 0301 0302 <li>e) Convey the object code using peer-to-peer transmission, provided 0303 you inform other peers where the object code and Corresponding 0304 Source of the work are being offered to the general public at no 0305 charge under subsection 6d.</li> 0306 </ul> 0307 0308 <p>A separable portion of the object code, whose source code is excluded 0309 from the Corresponding Source as a System Library, need not be 0310 included in conveying the object code work.</p> 0311 0312 <p>A “User Product” is either (1) a “consumer product”, which means any 0313 tangible personal property which is normally used for personal, family, 0314 or household purposes, or (2) anything designed or sold for incorporation 0315 into a dwelling. In determining whether a product is a consumer product, 0316 doubtful cases shall be resolved in favor of coverage. For a particular 0317 product received by a particular user, “normally used” refers to a 0318 typical or common use of that class of product, regardless of the status 0319 of the particular user or of the way in which the particular user 0320 actually uses, or expects or is expected to use, the product. A product 0321 is a consumer product regardless of whether the product has substantial 0322 commercial, industrial or non-consumer uses, unless such uses represent 0323 the only significant mode of use of the product.</p> 0324 0325 <p>“Installation Information” for a User Product means any methods, 0326 procedures, authorization keys, or other information required to install 0327 and execute modified versions of a covered work in that User Product from 0328 a modified version of its Corresponding Source. The information must 0329 suffice to ensure that the continued functioning of the modified object 0330 code is in no case prevented or interfered with solely because 0331 modification has been made.</p> 0332 0333 <p>If you convey an object code work under this section in, or with, or 0334 specifically for use in, a User Product, and the conveying occurs as 0335 part of a transaction in which the right of possession and use of the 0336 User Product is transferred to the recipient in perpetuity or for a 0337 fixed term (regardless of how the transaction is characterized), the 0338 Corresponding Source conveyed under this section must be accompanied 0339 by the Installation Information. But this requirement does not apply 0340 if neither you nor any third party retains the ability to install 0341 modified object code on the User Product (for example, the work has 0342 been installed in ROM).</p> 0343 0344 <p>The requirement to provide Installation Information does not include a 0345 requirement to continue to provide support service, warranty, or updates 0346 for a work that has been modified or installed by the recipient, or for 0347 the User Product in which it has been modified or installed. Access to a 0348 network may be denied when the modification itself materially and 0349 adversely affects the operation of the network or violates the rules and 0350 protocols for communication across the network.</p> 0351 0352 <p>Corresponding Source conveyed, and Installation Information provided, 0353 in accord with this section must be in a format that is publicly 0354 documented (and with an implementation available to the public in 0355 source code form), and must require no special password or key for 0356 unpacking, reading or copying.</p> 0357 0358 <h4><a name="section7"></a>7. Additional Terms.</h4> 0359 0360 <p>“Additional permissions” are terms that supplement the terms of this 0361 License by making exceptions from one or more of its conditions. 0362 Additional permissions that are applicable to the entire Program shall 0363 be treated as though they were included in this License, to the extent 0364 that they are valid under applicable law. If additional permissions 0365 apply only to part of the Program, that part may be used separately 0366 under those permissions, but the entire Program remains governed by 0367 this License without regard to the additional permissions.</p> 0368 0369 <p>When you convey a copy of a covered work, you may at your option 0370 remove any additional permissions from that copy, or from any part of 0371 it. (Additional permissions may be written to require their own 0372 removal in certain cases when you modify the work.) You may place 0373 additional permissions on material, added by you to a covered work, 0374 for which you have or can give appropriate copyright permission.</p> 0375 0376 <p>Notwithstanding any other provision of this License, for material you 0377 add to a covered work, you may (if authorized by the copyright holders of 0378 that material) supplement the terms of this License with terms:</p> 0379 0380 <ul> 0381 <li>a) Disclaiming warranty or limiting liability differently from the 0382 terms of sections 15 and 16 of this License; or</li> 0383 0384 <li>b) Requiring preservation of specified reasonable legal notices or 0385 author attributions in that material or in the Appropriate Legal 0386 Notices displayed by works containing it; or</li> 0387 0388 <li>c) Prohibiting misrepresentation of the origin of that material, or 0389 requiring that modified versions of such material be marked in 0390 reasonable ways as different from the original version; or</li> 0391 0392 <li>d) Limiting the use for publicity purposes of names of licensors or 0393 authors of the material; or</li> 0394 0395 <li>e) Declining to grant rights under trademark law for use of some 0396 trade names, trademarks, or service marks; or</li> 0397 0398 <li>f) Requiring indemnification of licensors and authors of that 0399 material by anyone who conveys the material (or modified versions of 0400 it) with contractual assumptions of liability to the recipient, for 0401 any liability that these contractual assumptions directly impose on 0402 those licensors and authors.</li> 0403 </ul> 0404 0405 <p>All other non-permissive additional terms are considered “further 0406 restrictions” within the meaning of section 10. If the Program as you 0407 received it, or any part of it, contains a notice stating that it is 0408 governed by this License along with a term that is a further 0409 restriction, you may remove that term. If a license document contains 0410 a further restriction but permits relicensing or conveying under this 0411 License, you may add to a covered work material governed by the terms 0412 of that license document, provided that the further restriction does 0413 not survive such relicensing or conveying.</p> 0414 0415 <p>If you add terms to a covered work in accord with this section, you 0416 must place, in the relevant source files, a statement of the 0417 additional terms that apply to those files, or a notice indicating 0418 where to find the applicable terms.</p> 0419 0420 <p>Additional terms, permissive or non-permissive, may be stated in the 0421 form of a separately written license, or stated as exceptions; 0422 the above requirements apply either way.</p> 0423 0424 <h4><a name="section8"></a>8. Termination.</h4> 0425 0426 <p>You may not propagate or modify a covered work except as expressly 0427 provided under this License. Any attempt otherwise to propagate or 0428 modify it is void, and will automatically terminate your rights under 0429 this License (including any patent licenses granted under the third 0430 paragraph of section 11).</p> 0431 0432 <p>However, if you cease all violation of this License, then your 0433 license from a particular copyright holder is reinstated (a) 0434 provisionally, unless and until the copyright holder explicitly and 0435 finally terminates your license, and (b) permanently, if the copyright 0436 holder fails to notify you of the violation by some reasonable means 0437 prior to 60 days after the cessation.</p> 0438 0439 <p>Moreover, your license from a particular copyright holder is 0440 reinstated permanently if the copyright holder notifies you of the 0441 violation by some reasonable means, this is the first time you have 0442 received notice of violation of this License (for any work) from that 0443 copyright holder, and you cure the violation prior to 30 days after 0444 your receipt of the notice.</p> 0445 0446 <p>Termination of your rights under this section does not terminate the 0447 licenses of parties who have received copies or rights from you under 0448 this License. If your rights have been terminated and not permanently 0449 reinstated, you do not qualify to receive new licenses for the same 0450 material under section 10.</p> 0451 0452 <h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4> 0453 0454 <p>You are not required to accept this License in order to receive or 0455 run a copy of the Program. Ancillary propagation of a covered work 0456 occurring solely as a consequence of using peer-to-peer transmission 0457 to receive a copy likewise does not require acceptance. However, 0458 nothing other than this License grants you permission to propagate or 0459 modify any covered work. These actions infringe copyright if you do 0460 not accept this License. Therefore, by modifying or propagating a 0461 covered work, you indicate your acceptance of this License to do so.</p> 0462 0463 <h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4> 0464 0465 <p>Each time you convey a covered work, the recipient automatically 0466 receives a license from the original licensors, to run, modify and 0467 propagate that work, subject to this License. You are not responsible 0468 for enforcing compliance by third parties with this License.</p> 0469 0470 <p>An “entity transaction” is a transaction transferring control of an 0471 organization, or substantially all assets of one, or subdividing an 0472 organization, or merging organizations. If propagation of a covered 0473 work results from an entity transaction, each party to that 0474 transaction who receives a copy of the work also receives whatever 0475 licenses to the work the party's predecessor in interest had or could 0476 give under the previous paragraph, plus a right to possession of the 0477 Corresponding Source of the work from the predecessor in interest, if 0478 the predecessor has it or can get it with reasonable efforts.</p> 0479 0480 <p>You may not impose any further restrictions on the exercise of the 0481 rights granted or affirmed under this License. For example, you may 0482 not impose a license fee, royalty, or other charge for exercise of 0483 rights granted under this License, and you may not initiate litigation 0484 (including a cross-claim or counterclaim in a lawsuit) alleging that 0485 any patent claim is infringed by making, using, selling, offering for 0486 sale, or importing the Program or any portion of it.</p> 0487 0488 <h4><a name="section11"></a>11. Patents.</h4> 0489 0490 <p>A “contributor” is a copyright holder who authorizes use under this 0491 License of the Program or a work on which the Program is based. The 0492 work thus licensed is called the contributor's “contributor version”.</p> 0493 0494 <p>A contributor's “essential patent claims” are all patent claims 0495 owned or controlled by the contributor, whether already acquired or 0496 hereafter acquired, that would be infringed by some manner, permitted 0497 by this License, of making, using, or selling its contributor version, 0498 but do not include claims that would be infringed only as a 0499 consequence of further modification of the contributor version. For 0500 purposes of this definition, “control” includes the right to grant 0501 patent sublicenses in a manner consistent with the requirements of 0502 this License.</p> 0503 0504 <p>Each contributor grants you a non-exclusive, worldwide, royalty-free 0505 patent license under the contributor's essential patent claims, to 0506 make, use, sell, offer for sale, import and otherwise run, modify and 0507 propagate the contents of its contributor version.</p> 0508 0509 <p>In the following three paragraphs, a “patent license” is any express 0510 agreement or commitment, however denominated, not to enforce a patent 0511 (such as an express permission to practice a patent or covenant not to 0512 sue for patent infringement). To “grant” such a patent license to a 0513 party means to make such an agreement or commitment not to enforce a 0514 patent against the party.</p> 0515 0516 <p>If you convey a covered work, knowingly relying on a patent license, 0517 and the Corresponding Source of the work is not available for anyone 0518 to copy, free of charge and under the terms of this License, through a 0519 publicly available network server or other readily accessible means, 0520 then you must either (1) cause the Corresponding Source to be so 0521 available, or (2) arrange to deprive yourself of the benefit of the 0522 patent license for this particular work, or (3) arrange, in a manner 0523 consistent with the requirements of this License, to extend the patent 0524 license to downstream recipients. “Knowingly relying” means you have 0525 actual knowledge that, but for the patent license, your conveying the 0526 covered work in a country, or your recipient's use of the covered work 0527 in a country, would infringe one or more identifiable patents in that 0528 country that you have reason to believe are valid.</p> 0529 0530 <p>If, pursuant to or in connection with a single transaction or 0531 arrangement, you convey, or propagate by procuring conveyance of, a 0532 covered work, and grant a patent license to some of the parties 0533 receiving the covered work authorizing them to use, propagate, modify 0534 or convey a specific copy of the covered work, then the patent license 0535 you grant is automatically extended to all recipients of the covered 0536 work and works based on it.</p> 0537 0538 <p>A patent license is “discriminatory” if it does not include within 0539 the scope of its coverage, prohibits the exercise of, or is 0540 conditioned on the non-exercise of one or more of the rights that are 0541 specifically granted under this License. You may not convey a covered 0542 work if you are a party to an arrangement with a third party that is 0543 in the business of distributing software, under which you make payment 0544 to the third party based on the extent of your activity of conveying 0545 the work, and under which the third party grants, to any of the 0546 parties who would receive the covered work from you, a discriminatory 0547 patent license (a) in connection with copies of the covered work 0548 conveyed by you (or copies made from those copies), or (b) primarily 0549 for and in connection with specific products or compilations that 0550 contain the covered work, unless you entered into that arrangement, 0551 or that patent license was granted, prior to 28 March 2007.</p> 0552 0553 <p>Nothing in this License shall be construed as excluding or limiting 0554 any implied license or other defenses to infringement that may 0555 otherwise be available to you under applicable patent law.</p> 0556 0557 <h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4> 0558 0559 <p>If conditions are imposed on you (whether by court order, agreement or 0560 otherwise) that contradict the conditions of this License, they do not 0561 excuse you from the conditions of this License. If you cannot convey a 0562 covered work so as to satisfy simultaneously your obligations under this 0563 License and any other pertinent obligations, then as a consequence you may 0564 not convey it at all. For example, if you agree to terms that obligate you 0565 to collect a royalty for further conveying from those to whom you convey 0566 the Program, the only way you could satisfy both those terms and this 0567 License would be to refrain entirely from conveying the Program.</p> 0568 0569 <h4><a name="section13"></a>13. Use with the GNU Affero General Public License.</h4> 0570 0571 <p>Notwithstanding any other provision of this License, you have 0572 permission to link or combine any covered work with a work licensed 0573 under version 3 of the GNU Affero General Public License into a single 0574 combined work, and to convey the resulting work. The terms of this 0575 License will continue to apply to the part which is the covered work, 0576 but the special requirements of the GNU Affero General Public License, 0577 section 13, concerning interaction through a network will apply to the 0578 combination as such.</p> 0579 0580 <h4><a name="section14"></a>14. Revised Versions of this License.</h4> 0581 0582 <p>The Free Software Foundation may publish revised and/or new versions of 0583 the GNU General Public License from time to time. Such new versions will 0584 be similar in spirit to the present version, but may differ in detail to 0585 address new problems or concerns.</p> 0586 0587 <p>Each version is given a distinguishing version number. If the 0588 Program specifies that a certain numbered version of the GNU General 0589 Public License “or any later version” applies to it, you have the 0590 option of following the terms and conditions either of that numbered 0591 version or of any later version published by the Free Software 0592 Foundation. If the Program does not specify a version number of the 0593 GNU General Public License, you may choose any version ever published 0594 by the Free Software Foundation.</p> 0595 0596 <p>If the Program specifies that a proxy can decide which future 0597 versions of the GNU General Public License can be used, that proxy's 0598 public statement of acceptance of a version permanently authorizes you 0599 to choose that version for the Program.</p> 0600 0601 <p>Later license versions may give you additional or different 0602 permissions. However, no additional obligations are imposed on any 0603 author or copyright holder as a result of your choosing to follow a 0604 later version.</p> 0605 0606 <h4><a name="section15"></a>15. Disclaimer of Warranty.</h4> 0607 0608 <p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 0609 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 0610 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY 0611 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 0612 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 0613 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 0614 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 0615 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p> 0616 0617 <h4><a name="section16"></a>16. Limitation of Liability.</h4> 0618 0619 <p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 0620 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 0621 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 0622 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 0623 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 0624 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 0625 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 0626 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 0627 SUCH DAMAGES.</p> 0628 0629 <h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4> 0630 0631 <p>If the disclaimer of warranty and limitation of liability provided 0632 above cannot be given local legal effect according to their terms, 0633 reviewing courts shall apply local law that most closely approximates 0634 an absolute waiver of all civil liability in connection with the 0635 Program, unless a warranty or assumption of liability accompanies a 0636 copy of the Program in return for a fee.</p> 0637 0638 <p>END OF TERMS AND CONDITIONS</p> 0639 0640 <h3><a name="howto"></a>How to Apply These Terms to Your New Programs</h3> 0641 0642 <p>If you develop a new program, and you want it to be of the greatest 0643 possible use to the public, the best way to achieve this is to make it 0644 free software which everyone can redistribute and change under these terms.</p> 0645 0646 <p>To do so, attach the following notices to the program. It is safest 0647 to attach them to the start of each source file to most effectively 0648 state the exclusion of warranty; and each file should have at least 0649 the “copyright” line and a pointer to where the full notice is found.</p> 0650 0651 <pre> <one line to give the program's name and a brief idea of what it does.> 0652 Copyright (C) <year> <name of author> 0653 0654 This program is free software: you can redistribute it and/or modify 0655 it under the terms of the GNU General Public License as published by 0656 the Free Software Foundation, either version 3 of the License, or 0657 (at your option) any later version. 0658 0659 This program is distributed in the hope that it will be useful, 0660 but WITHOUT ANY WARRANTY; without even the implied warranty of 0661 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Of course, your program's commands 0681 might be different; for a GUI interface, you would use an “about box”.</p> 0682 0683 <p>You should also get your employer (if you work as a programmer) or school, 0684 if any, to sign a “copyright disclaimer” for the program, if necessary. 0685 For more information on this, and how to apply and follow the GNU GPL, see 0686 <<a href="http://www.gnu.org/licenses/">http://www.gnu.org/licenses/</a>>.</p> 0687 0688 <p>The GNU General Public License does not permit incorporating your program 0689 into proprietary programs.
