| 18 | <h3><a name="preamble"></a>Preamble</h3>
|
|---|
| 19 |
|
|---|
| 20 | <p>The GNU General Public License is a free, copyleft license for
|
|---|
| 21 | software and other kinds of works.</p>
|
|---|
| 22 |
|
|---|
| 23 | <p>The licenses for most software and other practical works are designed
|
|---|
| 24 | to take away your freedom to share and change the works. By contrast,
|
|---|
| 25 | the GNU General Public License is intended to guarantee your freedom to
|
|---|
| 26 | share and change all versions of a program--to make sure it remains free
|
|---|
| 27 | software for all its users. We, the Free Software Foundation, use the
|
|---|
| 28 | GNU General Public License for most of our software; it applies also to
|
|---|
| 29 | any other work released this way by its authors. You can apply it to
|
|---|
| 30 | your programs, too.</p>
|
|---|
| 31 |
|
|---|
| 32 | <p>When we speak of free software, we are referring to freedom, not
|
|---|
| 33 | price. Our General Public Licenses are designed to make sure that you
|
|---|
| 34 | have the freedom to distribute copies of free software (and charge for
|
|---|
| 35 | them if you wish), that you receive source code or can get it if you
|
|---|
| 36 | want it, that you can change the software or use pieces of it in new
|
|---|
| 37 | free programs, and that you know you can do these things.</p>
|
|---|
| 38 |
|
|---|
| 39 | <p>To protect your rights, we need to prevent others from denying you
|
|---|
| 40 | these rights or asking you to surrender the rights. Therefore, you have
|
|---|
| 41 | certain responsibilities if you distribute copies of the software, or if
|
|---|
| 42 | you modify it: responsibilities to respect the freedom of others.</p>
|
|---|
| 43 |
|
|---|
| 44 | <p>For example, if you distribute copies of such a program, whether
|
|---|
| 45 | gratis or for a fee, you must pass on to the recipients the same
|
|---|
| 46 | freedoms that you received. You must make sure that they, too, receive
|
|---|
| 47 | or can get the source code. And you must show them these terms so they
|
|---|
| 48 | know their rights.</p>
|
|---|
| 49 |
|
|---|
| 50 | <p>Developers that use the GNU GPL protect your rights with two steps:
|
|---|
| 51 | (1) assert copyright on the software, and (2) offer you this License
|
|---|
| 52 | giving you legal permission to copy, distribute and/or modify it.</p>
|
|---|
| 53 |
|
|---|
| 54 | <p>For the developers' and authors' protection, the GPL clearly explains
|
|---|
| 55 | that there is no warranty for this free software. For both users' and
|
|---|
| 56 | authors' sake, the GPL requires that modified versions be marked as
|
|---|
| 57 | changed, so that their problems will not be attributed erroneously to
|
|---|
| 58 | authors of previous versions.</p>
|
|---|
| 59 |
|
|---|
| 60 | <p>Some devices are designed to deny users access to install or run
|
|---|
| 61 | modified versions of the software inside them, although the manufacturer
|
|---|
| 62 | can do so. This is fundamentally incompatible with the aim of
|
|---|
| 63 | protecting users' freedom to change the software. The systematic
|
|---|
| 64 | pattern of such abuse occurs in the area of products for individuals to
|
|---|
| 65 | use, which is precisely where it is most unacceptable. Therefore, we
|
|---|
| 66 | have designed this version of the GPL to prohibit the practice for those
|
|---|
| 67 | products. If such problems arise substantially in other domains, we
|
|---|
| 68 | stand ready to extend this provision to those domains in future versions
|
|---|
| 69 | of the GPL, as needed to protect the freedom of users.</p>
|
|---|
| 70 |
|
|---|
| 71 | <p>Finally, every program is threatened constantly by software patents.
|
|---|
| 72 | States should not allow patents to restrict development and use of
|
|---|
| 73 | software on general-purpose computers, but in those that do, we wish to
|
|---|
| 74 | avoid the special danger that patents applied to a free program could
|
|---|
| 75 | make it effectively proprietary. To prevent this, the GPL assures that
|
|---|
| 76 | patents cannot be used to render the program non-free.</p>
|
|---|
| 77 |
|
|---|
| 78 | <p>The precise terms and conditions for copying, distribution and
|
|---|
| 79 | modification follow.</p>
|
|---|
| 80 |
|
|---|
| 81 | <h3><a name="terms"></a>TERMS AND CONDITIONS</h3>
|
|---|
| 82 |
|
|---|
| 83 | <h4><a name="section0"></a>0. Definitions.</h4>
|
|---|
| 84 |
|
|---|
| 85 | <p>“This License” refers to version 3 of the GNU General Public License.</p>
|
|---|
| 86 |
|
|---|
| 87 | <p>“Copyright” also means copyright-like laws that apply to other kinds of
|
|---|
| 88 | works, such as semiconductor masks.</p>
|
|---|
| 89 |
|
|---|
| 90 | <p>“The Program” refers to any copyrightable work licensed under this
|
|---|
| 91 | License. Each licensee is addressed as “you”. “Licensees” and
|
|---|
| 92 | “recipients” may be individuals or organizations.</p>
|
|---|
| 93 |
|
|---|
| 94 | <p>To “modify” a work means to copy from or adapt all or part of the work
|
|---|
| 95 | in a fashion requiring copyright permission, other than the making of an
|
|---|
| 96 | exact copy. The resulting work is called a “modified version” of the
|
|---|
| 97 | earlier work or a work “based on” the earlier work.</p>
|
|---|
| 98 |
|
|---|
| 99 | <p>A “covered work” means either the unmodified Program or a work based
|
|---|
| 100 | on the Program.</p>
|
|---|
| 101 |
|
|---|
| 102 | <p>To “propagate” a work means to do anything with it that, without
|
|---|
| 103 | permission, would make you directly or secondarily liable for
|
|---|
| 104 | infringement under applicable copyright law, except executing it on a
|
|---|
| 105 | computer or modifying a private copy. Propagation includes copying,
|
|---|
| 106 | distribution (with or without modification), making available to the
|
|---|
| 107 | public, and in some countries other activities as well.</p>
|
|---|
| 108 |
|
|---|
| 109 | <p>To “convey” a work means any kind of propagation that enables other
|
|---|
| 110 | parties to make or receive copies. Mere interaction with a user through
|
|---|
| 111 | a computer network, with no transfer of a copy, is not conveying.</p>
|
|---|
| 112 |
|
|---|
| 113 | <p>An interactive user interface displays “Appropriate Legal Notices”
|
|---|
| 114 | to the extent that it includes a convenient and prominently visible
|
|---|
| 115 | feature that (1) displays an appropriate copyright notice, and (2)
|
|---|
| 116 | tells the user that there is no warranty for the work (except to the
|
|---|
| 117 | extent that warranties are provided), that licensees may convey the
|
|---|
| 118 | work under this License, and how to view a copy of this License. If
|
|---|
| 119 | the interface presents a list of user commands or options, such as a
|
|---|
| 120 | menu, a prominent item in the list meets this criterion.</p>
|
|---|
| 121 |
|
|---|
| 122 | <h4><a name="section1"></a>1. Source Code.</h4>
|
|---|
| 123 |
|
|---|
| 124 | <p>The “source code” for a work means the preferred form of the work
|
|---|
| 125 | for making modifications to it. “Object code” means any non-source
|
|---|
| 126 | form of a work.</p>
|
|---|
| 127 |
|
|---|
| 128 | <p>A “Standard Interface” means an interface that either is an official
|
|---|
| 129 | standard defined by a recognized standards body, or, in the case of
|
|---|
| 130 | interfaces specified for a particular programming language, one that
|
|---|
| 131 | is widely used among developers working in that language.</p>
|
|---|
| 132 |
|
|---|
| 133 | <p>The “System Libraries” of an executable work include anything, other
|
|---|
| 134 | than the work as a whole, that (a) is included in the normal form of
|
|---|
| 135 | packaging a Major Component, but which is not part of that Major
|
|---|
| 136 | Component, and (b) serves only to enable use of the work with that
|
|---|
| 137 | Major Component, or to implement a Standard Interface for which an
|
|---|
| 138 | implementation is available to the public in source code form. A
|
|---|
| 139 | “Major Component”, in this context, means a major essential component
|
|---|
| 140 | (kernel, window system, and so on) of the specific operating system
|
|---|
| 141 | (if any) on which the executable work runs, or a compiler used to
|
|---|
| 142 | produce the work, or an object code interpreter used to run it.</p>
|
|---|
| 143 |
|
|---|
| 144 | <p>The “Corresponding Source” for a work in object code form means all
|
|---|
| 145 | the source code needed to generate, install, and (for an executable
|
|---|
| 146 | work) run the object code and to modify the work, including scripts to
|
|---|
| 147 | control those activities. However, it does not include the work's
|
|---|
| 148 | System Libraries, or general-purpose tools or generally available free
|
|---|
| 149 | programs which are used unmodified in performing those activities but
|
|---|
| 150 | which are not part of the work. For example, Corresponding Source
|
|---|
| 151 | includes interface definition files associated with source files for
|
|---|
| 152 | the work, and the source code for shared libraries and dynamically
|
|---|
| 153 | linked subprograms that the work is specifically designed to require,
|
|---|
| 154 | such as by intimate data communication or control flow between those
|
|---|
| 155 | subprograms and other parts of the work.</p>
|
|---|
| 156 |
|
|---|
| 157 | <p>The Corresponding Source need not include anything that users
|
|---|
| 158 | can regenerate automatically from other parts of the Corresponding
|
|---|
| 159 | Source.</p>
|
|---|
| 160 |
|
|---|
| 161 | <p>The Corresponding Source for a work in source code form is that
|
|---|
| 162 | same work.</p>
|
|---|
| 163 |
|
|---|
| 164 | <h4><a name="section2"></a>2. Basic Permissions.</h4>
|
|---|
| 165 |
|
|---|
| 166 | <p>All rights granted under this License are granted for the term of
|
|---|
| 167 | copyright on the Program, and are irrevocable provided the stated
|
|---|
| 168 | conditions are met. This License explicitly affirms your unlimited
|
|---|
| 169 | permission to run the unmodified Program. The output from running a
|
|---|
| 170 | covered work is covered by this License only if the output, given its
|
|---|
| 171 | content, constitutes a covered work. This License acknowledges your
|
|---|
| 172 | rights of fair use or other equivalent, as provided by copyright law.</p>
|
|---|
| 173 |
|
|---|
| 174 | <p>You may make, run and propagate covered works that you do not
|
|---|
| 175 | convey, without conditions so long as your license otherwise remains
|
|---|
| 176 | in force. You may convey covered works to others for the sole purpose
|
|---|
| 177 | of having them make modifications exclusively for you, or provide you
|
|---|
| 178 | with facilities for running those works, provided that you comply with
|
|---|
| 179 | the terms of this License in conveying all material for which you do
|
|---|
| 180 | not control copyright. Those thus making or running the covered works
|
|---|
| 181 | for you must do so exclusively on your behalf, under your direction
|
|---|
| 182 | and control, on terms that prohibit them from making any copies of
|
|---|
| 183 | your copyrighted material outside their relationship with you.</p>
|
|---|
| 184 |
|
|---|
| 185 | <p>Conveying under any other circumstances is permitted solely under
|
|---|
| 186 | the conditions stated below. Sublicensing is not allowed; section 10
|
|---|
| 187 | makes it unnecessary.</p>
|
|---|
| 188 |
|
|---|
| 189 | <h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4>
|
|---|
| 190 |
|
|---|
| 191 | <p>No covered work shall be deemed part of an effective technological
|
|---|
| 192 | measure under any applicable law fulfilling obligations under article
|
|---|
| 193 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
|---|
| 194 | similar laws prohibiting or restricting circumvention of such
|
|---|
| 195 | measures.</p>
|
|---|
| 196 |
|
|---|
| 197 | <p>When you convey a covered work, you waive any legal power to forbid
|
|---|
| 198 | circumvention of technological measures to the extent such circumvention
|
|---|
| 199 | is effected by exercising rights under this License with respect to
|
|---|
| 200 | the covered work, and you disclaim any intention to limit operation or
|
|---|
| 201 | modification of the work as a means of enforcing, against the work's
|
|---|
| 202 | users, your or third parties' legal rights to forbid circumvention of
|
|---|
| 203 | technological measures.</p>
|
|---|
| 204 |
|
|---|
| 205 | <h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4>
|
|---|
| 206 |
|
|---|
| 207 | <p>You may convey verbatim copies of the Program's source code as you
|
|---|
| 208 | receive it, in any medium, provided that you conspicuously and
|
|---|
| 209 | appropriately publish on each copy an appropriate copyright notice;
|
|---|
| 210 | keep intact all notices stating that this License and any
|
|---|
| 211 | non-permissive terms added in accord with section 7 apply to the code;
|
|---|
| 212 | keep intact all notices of the absence of any warranty; and give all
|
|---|
| 213 | recipients a copy of this License along with the Program.</p>
|
|---|
| 214 |
|
|---|
| 215 | <p>You may charge any price or no price for each copy that you convey,
|
|---|
| 216 | and you may offer support or warranty protection for a fee.</p>
|
|---|
| 217 |
|
|---|
| 218 | <h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4>
|
|---|
| 219 |
|
|---|
| 220 | <p>You may convey a work based on the Program, or the modifications to
|
|---|
| 221 | produce it from the Program, in the form of source code under the
|
|---|
| 222 | terms of section 4, provided that you also meet all of these conditions:</p>
|
|---|
| 223 |
|
|---|
| 224 | <ul>
|
|---|
| 225 | <li>a) The work must carry prominent notices stating that you modified
|
|---|
| 226 | it, and giving a relevant date.</li>
|
|---|
| 227 |
|
|---|
| 228 | <li>b) The work must carry prominent notices stating that it is
|
|---|
| 229 | released under this License and any conditions added under section
|
|---|
| 230 | 7. This requirement modifies the requirement in section 4 to
|
|---|
| 231 | “keep intact all notices”.</li>
|
|---|
| 232 |
|
|---|
| 233 | <li>c) You must license the entire work, as a whole, under this
|
|---|
| 234 | License to anyone who comes into possession of a copy. This
|
|---|
| 235 | License will therefore apply, along with any applicable section 7
|
|---|
| 236 | additional terms, to the whole of the work, and all its parts,
|
|---|
| 237 | regardless of how they are packaged. This License gives no
|
|---|
| 238 | permission to license the work in any other way, but it does not
|
|---|
| 239 | invalidate such permission if you have separately received it.</li>
|
|---|
| 240 |
|
|---|
| 241 | <li>d) If the work has interactive user interfaces, each must display
|
|---|
| 242 | Appropriate Legal Notices; however, if the Program has interactive
|
|---|
| 243 | interfaces that do not display Appropriate Legal Notices, your
|
|---|
| 244 | work need not make them do so.</li>
|
|---|
| 245 | </ul>
|
|---|
| 246 |
|
|---|
| 247 | <p>A compilation of a covered work with other separate and independent
|
|---|
| 248 | works, which are not by their nature extensions of the covered work,
|
|---|
| 249 | and which are not combined with it such as to form a larger program,
|
|---|
| 250 | in or on a volume of a storage or distribution medium, is called an
|
|---|
| 251 | “aggregate” if the compilation and its resulting copyright are not
|
|---|
| 252 | used to limit the access or legal rights of the compilation's users
|
|---|
| 253 | beyond what the individual works permit. Inclusion of a covered work
|
|---|
| 254 | in an aggregate does not cause this License to apply to the other
|
|---|
| 255 | parts of the aggregate.</p>
|
|---|
| 256 |
|
|---|
| 257 | <h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4>
|
|---|
| 258 |
|
|---|
| 259 | <p>You may convey a covered work in object code form under the terms
|
|---|
| 260 | of sections 4 and 5, provided that you also convey the
|
|---|
| 261 | machine-readable Corresponding Source under the terms of this License,
|
|---|
| 262 | in one of these ways:</p>
|
|---|
| 263 |
|
|---|
| 264 | <ul>
|
|---|
| 265 | <li>a) Convey the object code in, or embodied in, a physical product
|
|---|
| 266 | (including a physical distribution medium), accompanied by the
|
|---|
| 267 | Corresponding Source fixed on a durable physical medium
|
|---|
| 268 | customarily used for software interchange.</li>
|
|---|
| 269 |
|
|---|
| 270 | <li>b) Convey the object code in, or embodied in, a physical product
|
|---|
| 271 | (including a physical distribution medium), accompanied by a
|
|---|
| 272 | written offer, valid for at least three years and valid for as
|
|---|
| 273 | long as you offer spare parts or customer support for that product
|
|---|
| 274 | model, to give anyone who possesses the object code either (1) a
|
|---|
| 275 | copy of the Corresponding Source for all the software in the
|
|---|
| 276 | product that is covered by this License, on a durable physical
|
|---|
| 277 | medium customarily used for software interchange, for a price no
|
|---|
| 278 | more than your reasonable cost of physically performing this
|
|---|
| 279 | conveying of source, or (2) access to copy the
|
|---|
| 280 | Corresponding Source from a network server at no charge.</li>
|
|---|
| 281 |
|
|---|
| 282 | <li>c) Convey individual copies of the object code with a copy of the
|
|---|
| 283 | written offer to provide the Corresponding Source. This
|
|---|
| 284 | alternative is allowed only occasionally and noncommercially, and
|
|---|
| 285 | only if you received the object code with such an offer, in accord
|
|---|
| 286 | with subsection 6b.</li>
|
|---|
| 287 |
|
|---|
| 288 | <li>d) Convey the object code by offering access from a designated
|
|---|
| 289 | place (gratis or for a charge), and offer equivalent access to the
|
|---|
| 290 | Corresponding Source in the same way through the same place at no
|
|---|
| 291 | further charge. You need not require recipients to copy the
|
|---|
| 292 | Corresponding Source along with the object code. If the place to
|
|---|
| 293 | copy the object code is a network server, the Corresponding Source
|
|---|
| 294 | may be on a different server (operated by you or a third party)
|
|---|
| 295 | that supports equivalent copying facilities, provided you maintain
|
|---|
| 296 | clear directions next to the object code saying where to find the
|
|---|
| 297 | Corresponding Source. Regardless of what server hosts the
|
|---|
| 298 | Corresponding Source, you remain obligated to ensure that it is
|
|---|
| 299 | available for as long as needed to satisfy these requirements.</li>
|
|---|
| 300 |
|
|---|
| 301 | <li>e) Convey the object code using peer-to-peer transmission, provided
|
|---|
| 302 | you inform other peers where the object code and Corresponding
|
|---|
| 303 | Source of the work are being offered to the general public at no
|
|---|
| 304 | charge under subsection 6d.</li>
|
|---|
| 305 | </ul>
|
|---|
| 306 |
|
|---|
| 307 | <p>A separable portion of the object code, whose source code is excluded
|
|---|
| 308 | from the Corresponding Source as a System Library, need not be
|
|---|
| 309 | included in conveying the object code work.</p>
|
|---|
| 310 |
|
|---|
| 311 | <p>A “User Product” is either (1) a “consumer product”, which means any
|
|---|
| 312 | tangible personal property which is normally used for personal, family,
|
|---|
| 313 | or household purposes, or (2) anything designed or sold for incorporation
|
|---|
| 314 | into a dwelling. In determining whether a product is a consumer product,
|
|---|
| 315 | doubtful cases shall be resolved in favor of coverage. For a particular
|
|---|
| 316 | product received by a particular user, “normally used” refers to a
|
|---|
| 317 | typical or common use of that class of product, regardless of the status
|
|---|
| 318 | of the particular user or of the way in which the particular user
|
|---|
| 319 | actually uses, or expects or is expected to use, the product. A product
|
|---|
| 320 | is a consumer product regardless of whether the product has substantial
|
|---|
| 321 | commercial, industrial or non-consumer uses, unless such uses represent
|
|---|
| 322 | the only significant mode of use of the product.</p>
|
|---|
| 323 |
|
|---|
| 324 | <p>“Installation Information” for a User Product means any methods,
|
|---|
| 325 | procedures, authorization keys, or other information required to install
|
|---|
| 326 | and execute modified versions of a covered work in that User Product from
|
|---|
| 327 | a modified version of its Corresponding Source. The information must
|
|---|
| 328 | suffice to ensure that the continued functioning of the modified object
|
|---|
| 329 | code is in no case prevented or interfered with solely because
|
|---|
| 330 | modification has been made.</p>
|
|---|
| 331 |
|
|---|
| 332 | <p>If you convey an object code work under this section in, or with, or
|
|---|
| 333 | specifically for use in, a User Product, and the conveying occurs as
|
|---|
| 334 | part of a transaction in which the right of possession and use of the
|
|---|
| 335 | User Product is transferred to the recipient in perpetuity or for a
|
|---|
| 336 | fixed term (regardless of how the transaction is characterized), the
|
|---|
| 337 | Corresponding Source conveyed under this section must be accompanied
|
|---|
| 338 | by the Installation Information. But this requirement does not apply
|
|---|
| 339 | if neither you nor any third party retains the ability to install
|
|---|
| 340 | modified object code on the User Product (for example, the work has
|
|---|
| 341 | been installed in ROM).</p>
|
|---|
| 342 |
|
|---|
| 343 | <p>The requirement to provide Installation Information does not include a
|
|---|
| 344 | requirement to continue to provide support service, warranty, or updates
|
|---|
| 345 | for a work that has been modified or installed by the recipient, or for
|
|---|
| 346 | the User Product in which it has been modified or installed. Access to a
|
|---|
| 347 | network may be denied when the modification itself materially and
|
|---|
| 348 | adversely affects the operation of the network or violates the rules and
|
|---|
| 349 | protocols for communication across the network.</p>
|
|---|
| 350 |
|
|---|
| 351 | <p>Corresponding Source conveyed, and Installation Information provided,
|
|---|
| 352 | in accord with this section must be in a format that is publicly
|
|---|
| 353 | documented (and with an implementation available to the public in
|
|---|
| 354 | source code form), and must require no special password or key for
|
|---|
| 355 | unpacking, reading or copying.</p>
|
|---|
| 356 |
|
|---|
| 357 | <h4><a name="section7"></a>7. Additional Terms.</h4>
|
|---|
| 358 |
|
|---|
| 359 | <p>“Additional permissions” are terms that supplement the terms of this
|
|---|
| 360 | License by making exceptions from one or more of its conditions.
|
|---|
| 361 | Additional permissions that are applicable to the entire Program shall
|
|---|
| 362 | be treated as though they were included in this License, to the extent
|
|---|
| 363 | that they are valid under applicable law. If additional permissions
|
|---|
| 364 | apply only to part of the Program, that part may be used separately
|
|---|
| 365 | under those permissions, but the entire Program remains governed by
|
|---|
| 366 | this License without regard to the additional permissions.</p>
|
|---|
| 367 |
|
|---|
| 368 | <p>When you convey a copy of a covered work, you may at your option
|
|---|
| 369 | remove any additional permissions from that copy, or from any part of
|
|---|
| 370 | it. (Additional permissions may be written to require their own
|
|---|
| 371 | removal in certain cases when you modify the work.) You may place
|
|---|
| 372 | additional permissions on material, added by you to a covered work,
|
|---|
| 373 | for which you have or can give appropriate copyright permission.</p>
|
|---|
| 374 |
|
|---|
| 375 | <p>Notwithstanding any other provision of this License, for material you
|
|---|
| 376 | add to a covered work, you may (if authorized by the copyright holders of
|
|---|
| 377 | that material) supplement the terms of this License with terms:</p>
|
|---|
| 378 |
|
|---|
| 379 | <ul>
|
|---|
| 380 | <li>a) Disclaiming warranty or limiting liability differently from the
|
|---|
| 381 | terms of sections 15 and 16 of this License; or</li>
|
|---|
| 382 |
|
|---|
| 383 | <li>b) Requiring preservation of specified reasonable legal notices or
|
|---|
| 384 | author attributions in that material or in the Appropriate Legal
|
|---|
| 385 | Notices displayed by works containing it; or</li>
|
|---|
| 386 |
|
|---|
| 387 | <li>c) Prohibiting misrepresentation of the origin of that material, or
|
|---|
| 388 | requiring that modified versions of such material be marked in
|
|---|
| 389 | reasonable ways as different from the original version; or</li>
|
|---|
| 390 |
|
|---|
| 391 | <li>d) Limiting the use for publicity purposes of names of licensors or
|
|---|
| 392 | authors of the material; or</li>
|
|---|
| 393 |
|
|---|
| 394 | <li>e) Declining to grant rights under trademark law for use of some
|
|---|
| 395 | trade names, trademarks, or service marks; or</li>
|
|---|
| 396 |
|
|---|
| 397 | <li>f) Requiring indemnification of licensors and authors of that
|
|---|
| 398 | material by anyone who conveys the material (or modified versions of
|
|---|
| 399 | it) with contractual assumptions of liability to the recipient, for
|
|---|
| 400 | any liability that these contractual assumptions directly impose on
|
|---|
| 401 | those licensors and authors.</li>
|
|---|
| 402 | </ul>
|
|---|
| 403 |
|
|---|
| 404 | <p>All other non-permissive additional terms are considered “further
|
|---|
| 405 | restrictions” within the meaning of section 10. If the Program as you
|
|---|
| 406 | received it, or any part of it, contains a notice stating that it is
|
|---|
| 407 | governed by this License along with a term that is a further
|
|---|
| 408 | restriction, you may remove that term. If a license document contains
|
|---|
| 409 | a further restriction but permits relicensing or conveying under this
|
|---|
| 410 | License, you may add to a covered work material governed by the terms
|
|---|
| 411 | of that license document, provided that the further restriction does
|
|---|
| 412 | not survive such relicensing or conveying.</p>
|
|---|
| 413 |
|
|---|
| 414 | <p>If you add terms to a covered work in accord with this section, you
|
|---|
| 415 | must place, in the relevant source files, a statement of the
|
|---|
| 416 | additional terms that apply to those files, or a notice indicating
|
|---|
| 417 | where to find the applicable terms.</p>
|
|---|
| 418 |
|
|---|
| 419 | <p>Additional terms, permissive or non-permissive, may be stated in the
|
|---|
| 420 | form of a separately written license, or stated as exceptions;
|
|---|
| 421 | the above requirements apply either way.</p>
|
|---|
| 422 |
|
|---|
| 423 | <h4><a name="section8"></a>8. Termination.</h4>
|
|---|
| 424 |
|
|---|
| 425 | <p>You may not propagate or modify a covered work except as expressly
|
|---|
| 426 | provided under this License. Any attempt otherwise to propagate or
|
|---|
| 427 | modify it is void, and will automatically terminate your rights under
|
|---|
| 428 | this License (including any patent licenses granted under the third
|
|---|
| 429 | paragraph of section 11).</p>
|
|---|
| 430 |
|
|---|
| 431 | <p>However, if you cease all violation of this License, then your
|
|---|
| 432 | license from a particular copyright holder is reinstated (a)
|
|---|
| 433 | provisionally, unless and until the copyright holder explicitly and
|
|---|
| 434 | finally terminates your license, and (b) permanently, if the copyright
|
|---|
| 435 | holder fails to notify you of the violation by some reasonable means
|
|---|
| 436 | prior to 60 days after the cessation.</p>
|
|---|
| 437 |
|
|---|
| 438 | <p>Moreover, your license from a particular copyright holder is
|
|---|
| 439 | reinstated permanently if the copyright holder notifies you of the
|
|---|
| 440 | violation by some reasonable means, this is the first time you have
|
|---|
| 441 | received notice of violation of this License (for any work) from that
|
|---|
| 442 | copyright holder, and you cure the violation prior to 30 days after
|
|---|
| 443 | your receipt of the notice.</p>
|
|---|
| 444 |
|
|---|
| 445 | <p>Termination of your rights under this section does not terminate the
|
|---|
| 446 | licenses of parties who have received copies or rights from you under
|
|---|
| 447 | this License. If your rights have been terminated and not permanently
|
|---|
| 448 | reinstated, you do not qualify to receive new licenses for the same
|
|---|
| 449 | material under section 10.</p>
|
|---|
| 450 |
|
|---|
| 451 | <h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4>
|
|---|
| 452 |
|
|---|
| 453 | <p>You are not required to accept this License in order to receive or
|
|---|
| 454 | run a copy of the Program. Ancillary propagation of a covered work
|
|---|
| 455 | occurring solely as a consequence of using peer-to-peer transmission
|
|---|
| 456 | to receive a copy likewise does not require acceptance. However,
|
|---|
| 457 | nothing other than this License grants you permission to propagate or
|
|---|
| 458 | modify any covered work. These actions infringe copyright if you do
|
|---|
| 459 | not accept this License. Therefore, by modifying or propagating a
|
|---|
| 460 | covered work, you indicate your acceptance of this License to do so.</p>
|
|---|
| 461 |
|
|---|
| 462 | <h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4>
|
|---|
| 463 |
|
|---|
| 464 | <p>Each time you convey a covered work, the recipient automatically
|
|---|
| 465 | receives a license from the original licensors, to run, modify and
|
|---|
| 466 | propagate that work, subject to this License. You are not responsible
|
|---|
| 467 | for enforcing compliance by third parties with this License.</p>
|
|---|
| 468 |
|
|---|
| 469 | <p>An “entity transaction” is a transaction transferring control of an
|
|---|
| 470 | organization, or substantially all assets of one, or subdividing an
|
|---|
| 471 | organization, or merging organizations. If propagation of a covered
|
|---|
| 472 | work results from an entity transaction, each party to that
|
|---|
| 473 | transaction who receives a copy of the work also receives whatever
|
|---|
| 474 | licenses to the work the party's predecessor in interest had or could
|
|---|
| 475 | give under the previous paragraph, plus a right to possession of the
|
|---|
| 476 | Corresponding Source of the work from the predecessor in interest, if
|
|---|
| 477 | the predecessor has it or can get it with reasonable efforts.</p>
|
|---|
| 478 |
|
|---|
| 479 | <p>You may not impose any further restrictions on the exercise of the
|
|---|
| 480 | rights granted or affirmed under this License. For example, you may
|
|---|
| 481 | not impose a license fee, royalty, or other charge for exercise of
|
|---|
| 482 | rights granted under this License, and you may not initiate litigation
|
|---|
| 483 | (including a cross-claim or counterclaim in a lawsuit) alleging that
|
|---|
| 484 | any patent claim is infringed by making, using, selling, offering for
|
|---|
| 485 | sale, or importing the Program or any portion of it.</p>
|
|---|
| 486 |
|
|---|
| 487 | <h4><a name="section11"></a>11. Patents.</h4>
|
|---|
| 488 |
|
|---|
| 489 | <p>A “contributor” is a copyright holder who authorizes use under this
|
|---|
| 490 | License of the Program or a work on which the Program is based. The
|
|---|
| 491 | work thus licensed is called the contributor's “contributor version”.</p>
|
|---|
| 492 |
|
|---|
| 493 | <p>A contributor's “essential patent claims” are all patent claims
|
|---|
| 494 | owned or controlled by the contributor, whether already acquired or
|
|---|
| 495 | hereafter acquired, that would be infringed by some manner, permitted
|
|---|
| 496 | by this License, of making, using, or selling its contributor version,
|
|---|
| 497 | but do not include claims that would be infringed only as a
|
|---|
| 498 | consequence of further modification of the contributor version. For
|
|---|
| 499 | purposes of this definition, “control” includes the right to grant
|
|---|
| 500 | patent sublicenses in a manner consistent with the requirements of
|
|---|
| 501 | this License.</p>
|
|---|
| 502 |
|
|---|
| 503 | <p>Each contributor grants you a non-exclusive, worldwide, royalty-free
|
|---|
| 504 | patent license under the contributor's essential patent claims, to
|
|---|
| 505 | make, use, sell, offer for sale, import and otherwise run, modify and
|
|---|
| 506 | propagate the contents of its contributor version.</p>
|
|---|
| 507 |
|
|---|
| 508 | <p>In the following three paragraphs, a “patent license” is any express
|
|---|
| 509 | agreement or commitment, however denominated, not to enforce a patent
|
|---|
| 510 | (such as an express permission to practice a patent or covenant not to
|
|---|
| 511 | sue for patent infringement). To “grant” such a patent license to a
|
|---|
| 512 | party means to make such an agreement or commitment not to enforce a
|
|---|
| 513 | patent against the party.</p>
|
|---|
| 514 |
|
|---|
| 515 | <p>If you convey a covered work, knowingly relying on a patent license,
|
|---|
| 516 | and the Corresponding Source of the work is not available for anyone
|
|---|
| 517 | to copy, free of charge and under the terms of this License, through a
|
|---|
| 518 | publicly available network server or other readily accessible means,
|
|---|
| 519 | then you must either (1) cause the Corresponding Source to be so
|
|---|
| 520 | available, or (2) arrange to deprive yourself of the benefit of the
|
|---|
| 521 | patent license for this particular work, or (3) arrange, in a manner
|
|---|
| 522 | consistent with the requirements of this License, to extend the patent
|
|---|
| 523 | license to downstream recipients. “Knowingly relying” means you have
|
|---|
| 524 | actual knowledge that, but for the patent license, your conveying the
|
|---|
| 525 | covered work in a country, or your recipient's use of the covered work
|
|---|
| 526 | in a country, would infringe one or more identifiable patents in that
|
|---|
| 527 | country that you have reason to believe are valid.</p>
|
|---|
| 528 |
|
|---|
| 529 | <p>If, pursuant to or in connection with a single transaction or
|
|---|
| 530 | arrangement, you convey, or propagate by procuring conveyance of, a
|
|---|
| 531 | covered work, and grant a patent license to some of the parties
|
|---|
| 532 | receiving the covered work authorizing them to use, propagate, modify
|
|---|
| 533 | or convey a specific copy of the covered work, then the patent license
|
|---|
| 534 | you grant is automatically extended to all recipients of the covered
|
|---|
| 535 | work and works based on it.</p>
|
|---|
| 536 |
|
|---|
| 537 | <p>A patent license is “discriminatory” if it does not include within
|
|---|
| 538 | the scope of its coverage, prohibits the exercise of, or is
|
|---|
| 539 | conditioned on the non-exercise of one or more of the rights that are
|
|---|
| 540 | specifically granted under this License. You may not convey a covered
|
|---|
| 541 | work if you are a party to an arrangement with a third party that is
|
|---|
| 542 | in the business of distributing software, under which you make payment
|
|---|
| 543 | to the third party based on the extent of your activity of conveying
|
|---|
| 544 | the work, and under which the third party grants, to any of the
|
|---|
| 545 | parties who would receive the covered work from you, a discriminatory
|
|---|
| 546 | patent license (a) in connection with copies of the covered work
|
|---|
| 547 | conveyed by you (or copies made from those copies), or (b) primarily
|
|---|
| 548 | for and in connection with specific products or compilations that
|
|---|
| 549 | contain the covered work, unless you entered into that arrangement,
|
|---|
| 550 | or that patent license was granted, prior to 28 March 2007.</p>
|
|---|
| 551 |
|
|---|
| 552 | <p>Nothing in this License shall be construed as excluding or limiting
|
|---|
| 553 | any implied license or other defenses to infringement that may
|
|---|
| 554 | otherwise be available to you under applicable patent law.</p>
|
|---|
| 555 |
|
|---|
| 556 | <h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4>
|
|---|
| 557 |
|
|---|
| 558 | <p>If conditions are imposed on you (whether by court order, agreement or
|
|---|
| 559 | otherwise) that contradict the conditions of this License, they do not
|
|---|
| 560 | excuse you from the conditions of this License. If you cannot convey a
|
|---|
| 561 | covered work so as to satisfy simultaneously your obligations under this
|
|---|
| 562 | License and any other pertinent obligations, then as a consequence you may
|
|---|
| 563 | not convey it at all. For example, if you agree to terms that obligate you
|
|---|
| 564 | to collect a royalty for further conveying from those to whom you convey
|
|---|
| 565 | the Program, the only way you could satisfy both those terms and this
|
|---|
| 566 | License would be to refrain entirely from conveying the Program.</p>
|
|---|
| 567 |
|
|---|
| 568 | <h4><a name="section13"></a>13. Use with the GNU Affero General Public License.</h4>
|
|---|
| 569 |
|
|---|
| 570 | <p>Notwithstanding any other provision of this License, you have
|
|---|
| 571 | permission to link or combine any covered work with a work licensed
|
|---|
| 572 | under version 3 of the GNU Affero General Public License into a single
|
|---|
| 573 | combined work, and to convey the resulting work. The terms of this
|
|---|
| 574 | License will continue to apply to the part which is the covered work,
|
|---|
| 575 | but the special requirements of the GNU Affero General Public License,
|
|---|
| 576 | section 13, concerning interaction through a network will apply to the
|
|---|
| 577 | combination as such.</p>
|
|---|
| 578 |
|
|---|
| 579 | <h4><a name="section14"></a>14. Revised Versions of this License.</h4>
|
|---|
| 580 |
|
|---|
| 581 | <p>The Free Software Foundation may publish revised and/or new versions of
|
|---|
| 582 | the GNU General Public License from time to time. Such new versions will
|
|---|
| 583 | be similar in spirit to the present version, but may differ in detail to
|
|---|
| 584 | address new problems or concerns.</p>
|
|---|
| 585 |
|
|---|
| 586 | <p>Each version is given a distinguishing version number. If the
|
|---|
| 587 | Program specifies that a certain numbered version of the GNU General
|
|---|
| 588 | Public License “or any later version” applies to it, you have the
|
|---|
| 589 | option of following the terms and conditions either of that numbered
|
|---|
| 590 | version or of any later version published by the Free Software
|
|---|
| 591 | Foundation. If the Program does not specify a version number of the
|
|---|
| 592 | GNU General Public License, you may choose any version ever published
|
|---|
| 593 | by the Free Software Foundation.</p>
|
|---|
| 594 |
|
|---|
| 595 | <p>If the Program specifies that a proxy can decide which future
|
|---|
| 596 | versions of the GNU General Public License can be used, that proxy's
|
|---|
| 597 | public statement of acceptance of a version permanently authorizes you
|
|---|
| 598 | to choose that version for the Program.</p>
|
|---|
| 599 |
|
|---|
| 600 | <p>Later license versions may give you additional or different
|
|---|
| 601 | permissions. However, no additional obligations are imposed on any
|
|---|
| 602 | author or copyright holder as a result of your choosing to follow a
|
|---|
| 603 | later version.</p>
|
|---|
| 604 |
|
|---|
| 605 | <h4><a name="section15"></a>15. Disclaimer of Warranty.</h4>
|
|---|
| 606 |
|
|---|
| 607 | <p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
|
|---|
| 608 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
|
|---|
| 609 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY
|
|---|
| 610 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
|
|---|
| 611 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
|---|
| 612 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
|
|---|
| 613 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
|
|---|
| 614 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p>
|
|---|
| 615 |
|
|---|
| 616 | <h4><a name="section16"></a>16. Limitation of Liability.</h4>
|
|---|
| 617 |
|
|---|
| 618 | <p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
|---|
| 619 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
|
|---|
| 620 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
|
|---|
| 621 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
|
|---|
| 622 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
|
|---|
| 623 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
|
|---|
| 624 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
|
|---|
| 625 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
|
|---|
| 626 | SUCH DAMAGES.</p>

| 628 | <h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4>
|
|---|
| 629 |
|
|---|
| 630 | <p>If the disclaimer of warranty and limitation of liability provided
|
|---|
| 631 | above cannot be given local legal effect according to their terms,
|
|---|
| 632 | reviewing courts shall apply local law that most closely approximates
|
|---|
| 633 | an absolute waiver of all civil liability in connection with the
|
|---|

|

| 640 |
|
|---|
| 641 | <p>If you develop a new program, and you want it to be of the greatest
|
|---|
| 642 | possible use to the public, the best way to achieve this is to make it
|
|---|
| 643 | free software which everyone can redistribute and change under these terms.</p>
|
|---|
| 644 |
|
|---|
| 645 | <p>To do so, attach the following notices to the program. It is safest
|
|---|
| 646 | to attach them to the start of each source file to most effectively
|
|---|
| 647 | state the exclusion of warranty; and each file should have at least
|
|---|
| 648 | the “copyright” line and a pointer to where the full notice is found.</p>
|
|---|
| 649 |
|
|---|
| 650 | <pre> <one line to give the program's name and a brief idea of what it does.>

| 667 | <p>Also add information on how to contact you by electronic and paper mail.</p>
|
|---|
| 668 |
|
|---|
| 669 | <p>If the program does terminal interaction, make it output a short
|
|---|
| 670 | notice like this when it starts in an interactive mode:</p>

|

| 674 | This is free software, and you are welcome to redistribute it
|

|
|---|
| 676 | </pre>
|
|---|
| 677 |
|
|---|
| 678 | <p>The hypothetical commands `show w' and `show c' should show the appropriate
|
|---|
| 679 | parts of the General Public License. Of course, your program's commands
|
|---|
| 680 | might be different; for a GUI interface, you would use an “about box”.</p>
|
|---|
| 681 |
|
|---|
| 682 | <p>You should also get your employer (if you work as a programmer) or school,
|
|---|
| 683 | if any, to sign a “copyright disclaimer” for the program, if necessary.
