ch1_mpi 5 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
ch1_mpi 6 Everyone is permitted to copy and distribute verbatim copies
ch1_mpi 7 of this license document, but changing it is not allowed.
ch1_mpi 8
ch1_mpi 9 Preamble
ch1_mpi 10
ch1_mpi 11 The GNU General Public License is a free, copyleft license for
ch1_mpi 12 software and other kinds of works.
ch1_mpi 13
ch1_mpi 14 The licenses for most software and other practical works are designed
ch1_mpi 15 to take away your freedom to share and change the works. By contrast,
ch1_mpi 16 the GNU General Public License is intended to guarantee your freedom to
ch1_mpi 17 share and change all versions of a program--to make sure it remains free
ch1_mpi 18 software for all its users. We, the Free Software Foundation, use the
ch1_mpi 19 GNU General Public License for most of our software; it applies also to
ch1_mpi 20 any other work released this way by its authors. You can apply it to
ch1_mpi 21 your programs, too.
ch1_mpi 22
ch1_mpi 23 When we speak of free software, we are referring to freedom, not
ch1_mpi 24 price. Our General Public Licenses are designed to make sure that you
ch1_mpi 25 have the freedom to distribute copies of free software (and charge for
ch1_mpi 26 them if you wish), that you receive source code or can get it if you
ch1_mpi 27 want it, that you can change the software or use pieces of it in new
ch1_mpi 28 free programs, and that you know you can do these things.
ch1_mpi 29
ch1_mpi 30 To protect your rights, we need to prevent others from denying you
ch1_mpi 31 these rights or asking you to surrender the rights. Therefore, you have
ch1_mpi 32 certain responsibilities if you distribute copies of the software, or if
ch1_mpi 33 you modify it: responsibilities to respect the freedom of others.
ch1_mpi 34
ch1_mpi 35 For example, if you distribute copies of such a program, whether
ch1_mpi 36 gratis or for a fee, you must pass on to the recipients the same
ch1_mpi 37 freedoms that you received. You must make sure that they, too, receive
ch1_mpi 38 or can get the source code. And you must show them these terms so they
ch1_mpi 39 know their rights.
ch1_mpi 40
ch1_mpi 41 Developers that use the GNU GPL protect your rights with two steps:
ch1_mpi 42 (1) assert copyright on the software, and (2) offer you this License
ch1_mpi 43 giving you legal permission to copy, distribute and/or modify it.
ch1_mpi 44
ch1_mpi 45 For the developers' and authors' protection, the GPL clearly explains
ch1_mpi 46 that there is no warranty for this free software. For both users' and
ch1_mpi 47 authors' sake, the GPL requires that modified versions be marked as
ch1_mpi 48 changed, so that their problems will not be attributed erroneously to
ch1_mpi 49 authors of previous versions.
ch1_mpi 50
ch1_mpi 51 Some devices are designed to deny users access to install or run
ch1_mpi 52 modified versions of the software inside them, although the manufacturer
ch1_mpi 53 can do so. This is fundamentally incompatible with the aim of
ch1_mpi 54 protecting users' freedom to change the software. The systematic
ch1_mpi 55 pattern of such abuse occurs in the area of products for individuals to
ch1_mpi 56 use, which is precisely where it is most unacceptable. Therefore, we
ch1_mpi 57 have designed this version of the GPL to prohibit the practice for those
ch1_mpi 58 products. If such problems arise substantially in other domains, we
ch1_mpi 59 stand ready to extend this provision to those domains in future versions
ch1_mpi 60 of the GPL, as needed to protect the freedom of users.
ch1_mpi 61
ch1_mpi 62 Finally, every program is threatened constantly by software patents.
ch1_mpi 63 States should not allow patents to restrict development and use of
ch1_mpi 64 software on general-purpose computers, but in those that do, we wish to
ch1_mpi 65 avoid the special danger that patents applied to a free program could
ch1_mpi 66 make it effectively proprietary. To prevent this, the GPL assures that
ch1_mpi 67 patents cannot be used to render the program non-free.
ch1_mpi 68
ch1_mpi 69 The precise terms and conditions for copying, distribution and
ch1_mpi 70 modification follow.
ch1_mpi 71
ch1_mpi 72 TERMS AND CONDITIONS
ch1_mpi 73
ch1_mpi 74 0. Definitions.
ch1_mpi 75
ch1_mpi 76 "This License" refers to version 3 of the GNU General Public License.
ch1_mpi 77
ch1_mpi 78 "Copyright" also means copyright-like laws that apply to other kinds of
ch1_mpi 79 works, such as semiconductor masks.
ch1_mpi 80
ch1_mpi 81 "The Program" refers to any copyrightable work licensed under this
ch1_mpi 82 License. Each licensee is addressed as "you". "Licensees" and
ch1_mpi 83 "recipients" may be individuals or organizations.
ch1_mpi 84
ch1_mpi 85 To "modify" a work means to copy from or adapt all or part of the work
ch1_mpi 86 in a fashion requiring copyright permission, other than the making of an
ch1_mpi 87 exact copy. The resulting work is called a "modified version" of the
ch1_mpi 88 earlier work or a work "based on" the earlier work.
ch1_mpi 89
ch1_mpi 90 A "covered work" means either the unmodified Program or a work based
ch1_mpi 91 on the Program.
ch1_mpi 92
ch1_mpi 93 To "propagate" a work means to do anything with it that, without
ch1_mpi 94 permission, would make you directly or secondarily liable for
ch1_mpi 95 infringement under applicable copyright law, except executing it on a
ch1_mpi 96 computer or modifying a private copy. Propagation includes copying,
ch1_mpi 97 distribution (with or without modification), making available to the
ch1_mpi 98 public, and in some countries other activities as well.
ch1_mpi 99
ch1_mpi 100 To "convey" a work means any kind of propagation that enables other
ch1_mpi 101 parties to make or receive copies. Mere interaction with a user through
ch1_mpi 102 a computer network, with no transfer of a copy, is not conveying.
ch1_mpi 103
ch1_mpi 104 An interactive user interface displays "Appropriate Legal Notices"
ch1_mpi 105 to the extent that it includes a convenient and prominently visible
ch1_mpi 106 feature that (1) displays an appropriate copyright notice, and (2)
ch1_mpi 107 tells the user that there is no warranty for the work (except to the
ch1_mpi 108 extent that warranties are provided), that licensees may convey the
ch1_mpi 109 work under this License, and how to view a copy of this License. If
ch1_mpi 110 the interface presents a list of user commands or options, such as a
ch1_mpi 111 menu, a prominent item in the list meets this criterion.
ch1_mpi 112
ch1_mpi 113 1. Source Code.
ch1_mpi 114
ch1_mpi 115 The "source code" for a work means the preferred form of the work
ch1_mpi 116 for making modifications to it. "Object code" means any non-source
ch1_mpi 117 form of a work.
ch1_mpi 118
ch1_mpi 119 A "Standard Interface" means an interface that either is an official
ch1_mpi 120 standard defined by a recognized standards body, or, in the case of
ch1_mpi 121 interfaces specified for a particular programming language, one that
ch1_mpi 122 is widely used among developers working in that language.
ch1_mpi 123
ch1_mpi 124 The "System Libraries" of an executable work include anything, other
ch1_mpi 125 than the work as a whole, that (a) is included in the normal form of
ch1_mpi 126 packaging a Major Component, but which is not part of that Major
ch1_mpi 127 Component, and (b) serves only to enable use of the work with that
ch1_mpi 128 Major Component, or to implement a Standard Interface for which an
ch1_mpi 129 implementation is available to the public in source code form. A
ch1_mpi 130 "Major Component", in this context, means a major essential component
ch1_mpi 131 (kernel, window system, and so on) of the specific operating system
ch1_mpi 132 (if any) on which the executable work runs, or a compiler used to
ch1_mpi 133 produce the work, or an object code interpreter used to run it.
ch1_mpi 134
ch1_mpi 135 The "Corresponding Source" for a work in object code form means all
ch1_mpi 136 the source code needed to generate, install, and (for an executable
ch1_mpi 137 work) run the object code and to modify the work, including scripts to
ch1_mpi 138 control those activities. However, it does not include the work's
ch1_mpi 139 System Libraries, or general-purpose tools or generally available free
ch1_mpi 140 programs which are used unmodified in performing those activities but
ch1_mpi 141 which are not part of the work. For example, Corresponding Source
ch1_mpi 142 includes interface definition files associated with source files for
ch1_mpi 143 the work, and the source code for shared libraries and dynamically
ch1_mpi 144 linked subprograms that the work is specifically designed to require,
ch1_mpi 145 such as by intimate data communication or control flow between those
ch1_mpi 146 subprograms and other parts of the work.
ch1_mpi 147
ch1_mpi 148 The Corresponding Source need not include anything that users
ch1_mpi 149 can regenerate automatically from other parts of the Corresponding
ch1_mpi 150 Source.
ch1_mpi 151
ch1_mpi 152 The Corresponding Source for a work in source code form is that
ch1_mpi 153 same work.
ch1_mpi 154
ch1_mpi 155 2. Basic Permissions.
ch1_mpi 156
ch1_mpi 157 All rights granted under this License are granted for the term of
ch1_mpi 158 copyright on the Program, and are irrevocable provided the stated
ch1_mpi 159 conditions are met. This License explicitly affirms your unlimited
ch1_mpi 160 permission to run the unmodified Program. The output from running a
ch1_mpi 161 covered work is covered by this License only if the output, given its
ch1_mpi 162 content, constitutes a covered work. This License acknowledges your
ch1_mpi 163 rights of fair use or other equivalent, as provided by copyright law.
ch1_mpi 164
ch1_mpi 165 You may make, run and propagate covered works that you do not
ch1_mpi 166 convey, without conditions so long as your license otherwise remains
ch1_mpi 167 in force. You may convey covered works to others for the sole purpose
ch1_mpi 168 of having them make modifications exclusively for you, or provide you
ch1_mpi 169 with facilities for running those works, provided that you comply with
ch1_mpi 170 the terms of this License in conveying all material for which you do
ch1_mpi 171 not control copyright. Those thus making or running the covered works
ch1_mpi 172 for you must do so exclusively on your behalf, under your direction
ch1_mpi 173 and control, on terms that prohibit them from making any copies of
ch1_mpi 174 your copyrighted material outside their relationship with you.
ch1_mpi 175
ch1_mpi 176 Conveying under any other circumstances is permitted solely under
ch1_mpi 177 the conditions stated below. Sublicensing is not allowed; section 10
ch1_mpi 178 makes it unnecessary.
ch1_mpi 179
ch1_mpi 180 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
ch1_mpi 181
ch1_mpi 182 No covered work shall be deemed part of an effective technological
ch1_mpi 183 measure under any applicable law fulfilling obligations under article
ch1_mpi 184 11 of the WIPO copyright treaty adopted on 20 December 1996, or
ch1_mpi 185 similar laws prohibiting or restricting circumvention of such
ch1_mpi 186 measures.
ch1_mpi 187
ch1_mpi 188 When you convey a covered work, you waive any legal power to forbid
ch1_mpi 189 circumvention of technological measures to the extent such circumvention
ch1_mpi 190 is effected by exercising rights under this License with respect to
ch1_mpi 191 the covered work, and you disclaim any intention to limit operation or
ch1_mpi 192 modification of the work as a means of enforcing, against the work's
ch1_mpi 193 users, your or third parties' legal rights to forbid circumvention of
ch1_mpi 194 technological measures.
ch1_mpi 195
ch1_mpi 196 4. Conveying Verbatim Copies.
ch1_mpi 197
ch1_mpi 198 You may convey verbatim copies of the Program's source code as you
ch1_mpi 199 receive it, in any medium, provided that you conspicuously and
ch1_mpi 200 appropriately publish on each copy an appropriate copyright notice;
ch1_mpi 201 keep intact all notices stating that this License and any
ch1_mpi 202 non-permissive terms added in accord with section 7 apply to the code;
ch1_mpi 203 keep intact all notices of the absence of any warranty; and give all
ch1_mpi 204 recipients a copy of this License along with the Program.
ch1_mpi 205
ch1_mpi 206 You may charge any price or no price for each copy that you convey,
ch1_mpi 207 and you may offer support or warranty protection for a fee.
ch1_mpi 208
ch1_mpi 209 5. Conveying Modified Source Versions.
ch1_mpi 210
ch1_mpi 211 You may convey a work based on the Program, or the modifications to
ch1_mpi 212 produce it from the Program, in the form of source code under the
ch1_mpi 213 terms of section 4, provided that you also meet all of these conditions:
ch1_mpi 214
ch1_mpi 215 a) The work must carry prominent notices stating that you modified
ch1_mpi 216 it, and giving a relevant date.
ch1_mpi 217
ch1_mpi 218 b) The work must carry prominent notices stating that it is
ch1_mpi 219 released under this License and any conditions added under section
ch1_mpi 220 7. This requirement modifies the requirement in section 4 to
ch1_mpi 221 "keep intact all notices".
ch1_mpi 222
ch1_mpi 223 c) You must license the entire work, as a whole, under this
ch1_mpi 224 License to anyone who comes into possession of a copy. This
ch1_mpi 225 License will therefore apply, along with any applicable section 7
ch1_mpi 226 additional terms, to the whole of the work, and all its parts,
ch1_mpi 227 regardless of how they are packaged. This License gives no
ch1_mpi 228 permission to license the work in any other way, but it does not
ch1_mpi 229 invalidate such permission if you have separately received it.
ch1_mpi 230
ch1_mpi 231 d) If the work has interactive user interfaces, each must display
ch1_mpi 232 Appropriate Legal Notices; however, if the Program has interactive
ch1_mpi 233 interfaces that do not display Appropriate Legal Notices, your
ch1_mpi 234 work need not make them do so.
ch1_mpi 235
ch1_mpi 236 A compilation of a covered work with other separate and independent
ch1_mpi 237 works, which are not by their nature extensions of the covered work,
ch1_mpi 238 and which are not combined with it such as to form a larger program,
ch1_mpi 239 in or on a volume of a storage or distribution medium, is called an
ch1_mpi 240 "aggregate" if the compilation and its resulting copyright are not
ch1_mpi 241 used to limit the access or legal rights of the compilation's users
ch1_mpi 242 beyond what the individual works permit. Inclusion of a covered work
ch1_mpi 243 in an aggregate does not cause this License to apply to the other
ch1_mpi 244 parts of the aggregate.
ch1_mpi 245
ch1_mpi 246 6. Conveying Non-Source Forms.
ch1_mpi 247
ch1_mpi 248 You may convey a covered work in object code form under the terms
ch1_mpi 249 of sections 4 and 5, provided that you also convey the
ch1_mpi 250 machine-readable Corresponding Source under the terms of this License,
ch1_mpi 251 in one of these ways:
ch1_mpi 252
ch1_mpi 253 a) Convey the object code in, or embodied in, a physical product
ch1_mpi 254 (including a physical distribution medium), accompanied by the
ch1_mpi 255 Corresponding Source fixed on a durable physical medium
ch1_mpi 256 customarily used for software interchange.
ch1_mpi 257
ch1_mpi 258 b) Convey the object code in, or embodied in, a physical product
ch1_mpi 259 (including a physical distribution medium), accompanied by a
ch1_mpi 260 written offer, valid for at least three years and valid for as
ch1_mpi 261 long as you offer spare parts or customer support for that product
ch1_mpi 262 model, to give anyone who possesses the object code either (1) a
ch1_mpi 263 copy of the Corresponding Source for all the software in the
ch1_mpi 264 product that is covered by this License, on a durable physical
ch1_mpi 265 medium customarily used for software interchange, for a price no
ch1_mpi 266 more than your reasonable cost of physically performing this
ch1_mpi 267 conveying of source, or (2) access to copy the
ch1_mpi 268 Corresponding Source from a network server at no charge.
ch1_mpi 269
ch1_mpi 270 c) Convey individual copies of the object code with a copy of the
ch1_mpi 271 written offer to provide the Corresponding Source. This
ch1_mpi 272 alternative is allowed only occasionally and noncommercially, and
ch1_mpi 273 only if you received the object code with such an offer, in accord
ch1_mpi 274 with subsection 6b.
ch1_mpi 275
ch1_mpi 276 d) Convey the object code by offering access from a designated
ch1_mpi 277 place (gratis or for a charge), and offer equivalent access to the
ch1_mpi 278 Corresponding Source in the same way through the same place at no
ch1_mpi 279 further charge. You need not require recipients to copy the
ch1_mpi 280 Corresponding Source along with the object code. If the place to
ch1_mpi 281 copy the object code is a network server, the Corresponding Source
ch1_mpi 282 may be on a different server (operated by you or a third party)
ch1_mpi 283 that supports equivalent copying facilities, provided you maintain
ch1_mpi 284 clear directions next to the object code saying where to find the
ch1_mpi 285 Corresponding Source. Regardless of what server hosts the
ch1_mpi 286 Corresponding Source, you remain obligated to ensure that it is
ch1_mpi 287 available for as long as needed to satisfy these requirements.
ch1_mpi 288
ch1_mpi 289 e) Convey the object code using peer-to-peer transmission, provided
ch1_mpi 290 you inform other peers where the object code and Corresponding
ch1_mpi 291 Source of the work are being offered to the general public at no
ch1_mpi 292 charge under subsection 6d.
ch1_mpi 293
ch1_mpi 294 A separable portion of the object code, whose source code is excluded
ch1_mpi 295 from the Corresponding Source as a System Library, need not be
ch1_mpi 296 included in conveying the object code work.
ch1_mpi 297
ch1_mpi 298 A "User Product" is either (1) a "consumer product", which means any
ch1_mpi 299 tangible personal property which is normally used for personal, family,
ch1_mpi 300 or household purposes, or (2) anything designed or sold for incorporation
ch1_mpi 301 into a dwelling. In determining whether a product is a consumer product,
ch1_mpi 302 doubtful cases shall be resolved in favor of coverage. For a particular
ch1_mpi 303 product received by a particular user, "normally used" refers to a
ch1_mpi 304 typical or common use of that class of product, regardless of the status
ch1_mpi 305 of the particular user or of the way in which the particular user
ch1_mpi 306 actually uses, or expects or is expected to use, the product. A product
ch1_mpi 307 is a consumer product regardless of whether the product has substantial
ch1_mpi 308 commercial, industrial or non-consumer uses, unless such uses represent
ch1_mpi 309 the only significant mode of use of the product.
ch1_mpi 310
ch1_mpi 311 "Installation Information" for a User Product means any methods,
ch1_mpi 312 procedures, authorization keys, or other information required to install
ch1_mpi 313 and execute modified versions of a covered work in that User Product from
ch1_mpi 314 a modified version of its Corresponding Source. The information must
ch1_mpi 315 suffice to ensure that the continued functioning of the modified object
ch1_mpi 316 code is in no case prevented or interfered with solely because
ch1_mpi 317 modification has been made.
ch1_mpi 318
ch1_mpi 319 If you convey an object code work under this section in, or with, or
ch1_mpi 320 specifically for use in, a User Product, and the conveying occurs as
ch1_mpi 321 part of a transaction in which the right of possession and use of the
ch1_mpi 322 User Product is transferred to the recipient in perpetuity or for a
ch1_mpi 323 fixed term (regardless of how the transaction is characterized), the
ch1_mpi 324 Corresponding Source conveyed under this section must be accompanied
ch1_mpi 325 by the Installation Information. But this requirement does not apply
ch1_mpi 326 if neither you nor any third party retains the ability to install
ch1_mpi 327 modified object code on the User Product (for example, the work has
ch1_mpi 328 been installed in ROM).
ch1_mpi 329
ch1_mpi 330 The requirement to provide Installation Information does not include a
ch1_mpi 331 requirement to continue to provide support service, warranty, or updates
ch1_mpi 332 for a work that has been modified or installed by the recipient, or for
ch1_mpi 333 the User Product in which it has been modified or installed. Access to a
ch1_mpi 334 network may be denied when the modification itself materially and
ch1_mpi 335 adversely affects the operation of the network or violates the rules and
ch1_mpi 336 protocols for communication across the network.
ch1_mpi 337
ch1_mpi 338 Corresponding Source conveyed, and Installation Information provided,
ch1_mpi 339 in accord with this section must be in a format that is publicly
ch1_mpi 340 documented (and with an implementation available to the public in
ch1_mpi 341 source code form), and must require no special password or key for
ch1_mpi 342 unpacking, reading or copying.
ch1_mpi 343
ch1_mpi 344 7. Additional Terms.
ch1_mpi 345
ch1_mpi 346 "Additional permissions" are terms that supplement the terms of this
ch1_mpi 347 License by making exceptions from one or more of its conditions.
ch1_mpi 348 Additional permissions that are applicable to the entire Program shall
ch1_mpi 349 be treated as though they were included in this License, to the extent
ch1_mpi 350 that they are valid under applicable law. If additional permissions
ch1_mpi 351 apply only to part of the Program, that part may be used separately
ch1_mpi 352 under those permissions, but the entire Program remains governed by
ch1_mpi 353 this License without regard to the additional permissions.
ch1_mpi 354
ch1_mpi 355 When you convey a copy of a covered work, you may at your option
ch1_mpi 356 remove any additional permissions from that copy, or from any part of
ch1_mpi 357 it. (Additional permissions may be written to require their own
ch1_mpi 358 removal in certain cases when you modify the work.) You may place
ch1_mpi 359 additional permissions on material, added by you to a covered work,
ch1_mpi 360 for which you have or can give appropriate copyright permission.
ch1_mpi 361
ch1_mpi 362 Notwithstanding any other provision of this License, for material you
ch1_mpi 363 add to a covered work, you may (if authorized by the copyright holders of
ch1_mpi 364 that material) supplement the terms of this License with terms:
ch1_mpi 365
ch1_mpi 366 a) Disclaiming warranty or limiting liability differently from the
ch1_mpi 367 terms of sections 15 and 16 of this License; or
ch1_mpi 368
ch1_mpi 369 b) Requiring preservation of specified reasonable legal notices or
ch1_mpi 370 author attributions in that material or in the Appropriate Legal
ch1_mpi 371 Notices displayed by works containing it; or
ch1_mpi 372
ch1_mpi 373 c) Prohibiting misrepresentation of the origin of that material, or
ch1_mpi 374 requiring that modified versions of such material be marked in
ch1_mpi 375 reasonable ways as different from the original version; or
ch1_mpi 376
ch1_mpi 377 d) Limiting the use for publicity purposes of names of licensors or
ch1_mpi 378 authors of the material; or
ch1_mpi 379
ch1_mpi 380 e) Declining to grant rights under trademark law for use of some
ch1_mpi 381 trade names, trademarks, or service marks; or
ch1_mpi 382
ch1_mpi 383 f) Requiring indemnification of licensors and authors of that
ch1_mpi 384 material by anyone who conveys the material (or modified versions of
ch1_mpi 385 it) with contractual assumptions of liability to the recipient, for
ch1_mpi 386 any liability that these contractual assumptions directly impose on
ch1_mpi 387 those licensors and authors.
ch1_mpi 388
ch1_mpi 389 All other non-permissive additional terms are considered "further
ch1_mpi 390 restrictions" within the meaning of section 10. If the Program as you
ch1_mpi 391 received it, or any part of it, contains a notice stating that it is
ch1_mpi 392 governed by this License along with a term that is a further
ch1_mpi 393 restriction, you may remove that term. If a license document contains
ch1_mpi 394 a further restriction but permits relicensing or conveying under this
ch1_mpi 395 License, you may add to a covered work material governed by the terms
ch1_mpi 396 of that license document, provided that the further restriction does
ch1_mpi 397 not survive such relicensing or conveying.
ch1_mpi 398
ch1_mpi 399 If you add terms to a covered work in accord with this section, you
ch1_mpi 400 must place, in the relevant source files, a statement of the
ch1_mpi 401 additional terms that apply to those files, or a notice indicating
ch1_mpi 402 where to find the applicable terms.
ch1_mpi 403
ch1_mpi 404 Additional terms, permissive or non-permissive, may be stated in the
ch1_mpi 405 form of a separately written license, or stated as exceptions;
ch1_mpi 406 the above requirements apply either way.
ch1_mpi 407
ch1_mpi 408 8. Termination.
ch1_mpi 409
ch1_mpi 410 You may not propagate or modify a covered work except as expressly
ch1_mpi 411 provided under this License. Any attempt otherwise to propagate or
ch1_mpi 412 modify it is void, and will automatically terminate your rights under
ch1_mpi 413 this License (including any patent licenses granted under the third
ch1_mpi 414 paragraph of section 11).
ch1_mpi 415
ch1_mpi 416 However, if you cease all violation of this License, then your
ch1_mpi 417 license from a particular copyright holder is reinstated (a)
ch1_mpi 418 provisionally, unless and until the copyright holder explicitly and
ch1_mpi 419 finally terminates your license, and (b) permanently, if the copyright
ch1_mpi 420 holder fails to notify you of the violation by some reasonable means
ch1_mpi 421 prior to 60 days after the cessation.
ch1_mpi 422
ch1_mpi 423 Moreover, your license from a particular copyright holder is
ch1_mpi 424 reinstated permanently if the copyright holder notifies you of the
ch1_mpi 425 violation by some reasonable means, this is the first time you have
ch1_mpi 426 received notice of violation of this License (for any work) from that
ch1_mpi 427 copyright holder, and you cure the violation prior to 30 days after
ch1_mpi 428 your receipt of the notice.
ch1_mpi 429
ch1_mpi 430 Termination of your rights under this section does not terminate the
ch1_mpi 431 licenses of parties who have received copies or rights from you under
ch1_mpi 432 this License. If your rights have been terminated and not permanently
ch1_mpi 433 reinstated, you do not qualify to receive new licenses for the same
ch1_mpi 434 material under section 10.
ch1_mpi 435
ch1_mpi 436 9. Acceptance Not Required for Having Copies.
ch1_mpi 437
ch1_mpi 438 You are not required to accept this License in order to receive or
ch1_mpi 439 run a copy of the Program. Ancillary propagation of a covered work
ch1_mpi 440 occurring solely as a consequence of using peer-to-peer transmission
ch1_mpi 441 to receive a copy likewise does not require acceptance. However,
ch1_mpi 442 nothing other than this License grants you permission to propagate or
ch1_mpi 443 modify any covered work. These actions infringe copyright if you do
ch1_mpi 444 not accept this License. Therefore, by modifying or propagating a
ch1_mpi 445 covered work, you indicate your acceptance of this License to do so.
ch1_mpi 446
ch1_mpi 447 10. Automatic Licensing of Downstream Recipients.
ch1_mpi 448
ch1_mpi 449 Each time you convey a covered work, the recipient automatically
ch1_mpi 450 receives a license from the original licensors, to run, modify and
ch1_mpi 451 propagate that work, subject to this License. You are not responsible
ch1_mpi 452 for enforcing compliance by third parties with this License.
ch1_mpi 453
ch1_mpi 454 An "entity transaction" is a transaction transferring control of an
ch1_mpi 455 organization, or substantially all assets of one, or subdividing an
ch1_mpi 456 organization, or merging organizations. If propagation of a covered
ch1_mpi 457 work results from an entity transaction, each party to that
ch1_mpi 458 transaction who receives a copy of the work also receives whatever
ch1_mpi 459 licenses to the work the party's predecessor in interest had or could
ch1_mpi 460 give under the previous paragraph, plus a right to possession of the
ch1_mpi 461 Corresponding Source of the work from the predecessor in interest, if
ch1_mpi 462 the predecessor has it or can get it with reasonable efforts.
ch1_mpi 463
ch1_mpi 464 You may not impose any further restrictions on the exercise of the
ch1_mpi 465 rights granted or affirmed under this License. For example, you may
ch1_mpi 466 not impose a license fee, royalty, or other charge for exercise of
ch1_mpi 467 rights granted under this License, and you may not initiate litigation
ch1_mpi 468 (including a cross-claim or counterclaim in a lawsuit) alleging that
ch1_mpi 469 any patent claim is infringed by making, using, selling, offering for
ch1_mpi 470 sale, or importing the Program or any portion of it.
ch1_mpi 471
ch1_mpi 472 11. Patents.
ch1_mpi 473
ch1_mpi 474 A "contributor" is a copyright holder who authorizes use under this
ch1_mpi 475 License of the Program or a work on which the Program is based. The
ch1_mpi 476 work thus licensed is called the contributor's "contributor version".
ch1_mpi 477
ch1_mpi 478 A contributor's "essential patent claims" are all patent claims
ch1_mpi 479 owned or controlled by the contributor, whether already acquired or
ch1_mpi 480 hereafter acquired, that would be infringed by some manner, permitted
ch1_mpi 481 by this License, of making, using, or selling its contributor version,
ch1_mpi 482 but do not include claims that would be infringed only as a
ch1_mpi 483 consequence of further modification of the contributor version. For
ch1_mpi 484 purposes of this definition, "control" includes the right to grant
ch1_mpi 485 patent sublicenses in a manner consistent with the requirements of
ch1_mpi 486 this License.
ch1_mpi 487
ch1_mpi 488 Each contributor grants you a non-exclusive, worldwide, royalty-free
ch1_mpi 489 patent license under the contributor's essential patent claims, to
ch1_mpi 490 make, use, sell, offer for sale, import and otherwise run, modify and
ch1_mpi 491 propagate the contents of its contributor version.
ch1_mpi 492
ch1_mpi 493 In the following three paragraphs, a "patent license" is any express
ch1_mpi 494 agreement or commitment, however denominated, not to enforce a patent
ch1_mpi 495 (such as an express permission to practice a patent or covenant not to
ch1_mpi 496 sue for patent infringement). To "grant" such a patent license to a
ch1_mpi 497 party means to make such an agreement or commitment not to enforce a
ch1_mpi 498 patent against the party.
ch1_mpi 499
ch1_mpi 500 If you convey a covered work, knowingly relying on a patent license,
ch1_mpi 501 and the Corresponding Source of the work is not available for anyone
ch1_mpi 502 to copy, free of charge and under the terms of this License, through a
ch1_mpi 503 publicly available network server or other readily accessible means,
ch1_mpi 504 then you must either (1) cause the Corresponding Source to be so
ch1_mpi 505 available, or (2) arrange to deprive yourself of the benefit of the
ch1_mpi 506 patent license for this particular work, or (3) arrange, in a manner
ch1_mpi 507 consistent with the requirements of this License, to extend the patent
ch1_mpi 508 license to downstream recipients. "Knowingly relying" means you have
ch1_mpi 509 actual knowledge that, but for the patent license, your conveying the
ch1_mpi 510 covered work in a country, or your recipient's use of the covered work
ch1_mpi 511 in a country, would infringe one or more identifiable patents in that
ch1_mpi 512 country that you have reason to believe are valid.
ch1_mpi 513
ch1_mpi 514 If, pursuant to or in connection with a single transaction or
ch1_mpi 515 arrangement, you convey, or propagate by procuring conveyance of, a
ch1_mpi 516 covered work, and grant a patent license to some of the parties
ch1_mpi 517 receiving the covered work authorizing them to use, propagate, modify
ch1_mpi 518 or convey a specific copy of the covered work, then the patent license
ch1_mpi 519 you grant is automatically extended to all recipients of the covered
ch1_mpi 520 work and works based on it.
ch1_mpi 521
ch1_mpi 522 A patent license is "discriminatory" if it does not include within
ch1_mpi 523 the scope of its coverage, prohibits the exercise of, or is
ch1_mpi 524 conditioned on the non-exercise of one or more of the rights that are
ch1_mpi 525 specifically granted under this License. You may not convey a covered
ch1_mpi 526 work if you are a party to an arrangement with a third party that is
ch1_mpi 527 in the business of distributing software, under which you make payment
ch1_mpi 528 to the third party based on the extent of your activity of conveying
ch1_mpi 529 the work, and under which the third party grants, to any of the
ch1_mpi 530 parties who would receive the covered work from you, a discriminatory
ch1_mpi 531 patent license (a) in connection with copies of the covered work
ch1_mpi 532 conveyed by you (or copies made from those copies), or (b) primarily
ch1_mpi 533 for and in connection with specific products or compilations that
ch1_mpi 534 contain the covered work, unless you entered into that arrangement,
ch1_mpi 535 or that patent license was granted, prior to 28 March 2007.
ch1_mpi 536
ch1_mpi 537 Nothing in this License shall be construed as excluding or limiting
ch1_mpi 538 any implied license or other defenses to infringement that may
ch1_mpi 539 otherwise be available to you under applicable patent law.
ch1_mpi 540
ch1_mpi 541 12. No Surrender of Others' Freedom.
ch1_mpi 542
ch1_mpi 543 If conditions are imposed on you (whether by court order, agreement or
ch1_mpi 544 otherwise) that contradict the conditions of this License, they do not
ch1_mpi 545 excuse you from the conditions of this License. If you cannot convey a
ch1_mpi 546 covered work so as to satisfy simultaneously your obligations under this
ch1_mpi 547 License and any other pertinent obligations, then as a consequence you may
ch1_mpi 548 not convey it at all. For example, if you agree to terms that obligate you
ch1_mpi 549 to collect a royalty for further conveying from those to whom you convey
ch1_mpi 550 the Program, the only way you could satisfy both those terms and this
ch1_mpi 551 License would be to refrain entirely from conveying the Program.
ch1_mpi 552
ch1_mpi 553 13. Use with the GNU Affero General Public License.
ch1_mpi 554
ch1_mpi 555 Notwithstanding any other provision of this License, you have
ch1_mpi 556 permission to link or combine any covered work with a work licensed
ch1_mpi 557 under version 3 of the GNU Affero General Public License into a single
ch1_mpi 558 combined work, and to convey the resulting work. The terms of this
ch1_mpi 559 License will continue to apply to the part which is the covered work,
ch1_mpi 560 but the special requirements of the GNU Affero General Public License,
ch1_mpi 561 section 13, concerning interaction through a network will apply to the
ch1_mpi 562 combination as such.
ch1_mpi 563
ch1_mpi 564 14. Revised Versions of this License.
ch1_mpi 565
ch1_mpi 566 The Free Software Foundation may publish revised and/or new versions of
ch1_mpi 567 the GNU General Public License from time to time. Such new versions will
ch1_mpi 568 be similar in spirit to the present version, but may differ in detail to
ch1_mpi 569 address new problems or concerns.
ch1_mpi 570
ch1_mpi 571 Each version is given a distinguishing version number. If the
ch1_mpi 572 Program specifies that a certain numbered version of the GNU General
ch1_mpi 573 Public License "or any later version" applies to it, you have the
ch1_mpi 574 option of following the terms and conditions either of that numbered
ch1_mpi 575 version or of any later version published by the Free Software
ch1_mpi 576 Foundation. If the Program does not specify a version number of the
ch1_mpi 577 GNU General Public License, you may choose any version ever published
ch1_mpi 578 by the Free Software Foundation.
ch1_mpi 579
ch1_mpi 580 If the Program specifies that a proxy can decide which future
ch1_mpi 581 versions of the GNU General Public License can be used, that proxy's
ch1_mpi 582 public statement of acceptance of a version permanently authorizes you
ch1_mpi 583 to choose that version for the Program.
ch1_mpi 584
ch1_mpi 585 Later license versions may give you additional or different
ch1_mpi 586 permissions. However, no additional obligations are imposed on any
ch1_mpi 587 author or copyright holder as a result of your choosing to follow a
ch1_mpi 588 later version.
ch1_mpi 589
ch1_mpi 590 15. Disclaimer of Warranty.
ch1_mpi 591
ch1_mpi 592 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
ch1_mpi 593 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
ch1_mpi 594 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
ch1_mpi 595 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
ch1_mpi 596 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
ch1_mpi 597 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
ch1_mpi 598 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ch1_mpi 599 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
ch1_mpi 600
ch1_mpi 601 16. Limitation of Liability.
ch1_mpi 602
ch1_mpi 603 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
ch1_mpi 604 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
ch1_mpi 605 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
ch1_mpi 606 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
ch1_mpi 607 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
ch1_mpi 608 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
ch1_mpi 609 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
ch1_mpi 610 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
ch1_mpi 611 SUCH DAMAGES.
ch1_mpi 612
ch1_mpi 613 17. Interpretation of Sections 15 and 16.
ch1_mpi 614
ch1_mpi 615 If the disclaimer of warranty and limitation of liability provided
ch1_mpi 616 above cannot be given local legal effect according to their terms,
ch1_mpi 617 reviewing courts shall apply local law that most closely approximates
ch1_mpi 618 an absolute waiver of all civil liability in connection with the
ch1_mpi 619 Program, unless a warranty or assumption of liability accompanies a
ch1_mpi 620 copy of the Program in return for a fee.
ch1_mpi 621
ch1_mpi 622 END OF TERMS AND CONDITIONS
ch1_mpi 623
ch1_mpi 624 How to Apply These Terms to Your New Programs
ch1_mpi 625
ch1_mpi 626 If you develop a new program, and you want it to be of the greatest
ch1_mpi 627 possible use to the public, the best way to achieve this is to make it
ch1_mpi 628 free software which everyone can redistribute and change under these terms.
ch1_mpi 629
ch1_mpi 630 To do so, attach the following notices to the program. It is safest
ch1_mpi 631 to attach them to the start of each source file to most effectively
ch1_mpi 632 state the exclusion of warranty; and each file should have at least
ch1_mpi 633 the "copyright" line and a pointer to where the full notice is found.
ch1_mpi 634
ch1_mpi 635 <one line to give the program's name and a brief idea of what it does.>
ch1_mpi 636 Copyright (C) <year> <name of author>
ch1_mpi 637
ch1_mpi 638 This program is free software: you can redistribute it and/or modify
ch1_mpi 639 it under the terms of the GNU General Public License as published by
ch1_mpi 640 the Free Software Foundation, either version 3 of the License, or
ch1_mpi 641 (at your option) any later version.
ch1_mpi 642
ch1_mpi 643 This program is distributed in the hope that it will be useful,
ch1_mpi 644 but WITHOUT ANY WARRANTY; without even the implied warranty of
ch1_mpi 645 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
ch1_mpi 646 GNU General Public License for more details.
ch1_mpi 647
ch1_mpi 648 You should have received a copy of the GNU General Public License
ch1_mpi 649 along with this program. If not, see <http://www.gnu.org/licenses/>.
ch1_mpi 650
ch1_mpi 651 Also add information on how to contact you by electronic and paper mail.
ch1_mpi 652
ch1_mpi 653 If the program does terminal interaction, make it output a short
ch1_mpi 654 notice like this when it starts in an interactive mode:
ch1_mpi 655
ch1_mpi 656 <program> Copyright (C) <year> <name of author>
ch1_mpi 657 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
ch1_mpi 658 This is free software, and you are welcome to redistribute it
ch1_mpi 659 under certain conditions; type `show c' for details.
ch1_mpi 660
ch1_mpi 661 The hypothetical commands `show w' and `show c' should show the appropriate
ch1_mpi 662 parts of the General Public License. Of course, your program's commands
ch1_mpi 663 might be different; for a GUI interface, you would use an "about box".
ch1_mpi 664
ch1_mpi 665 You should also get your employer (if you work as a programmer) or school,
ch1_mpi 666 if any, to sign a "copyright disclaimer" for the program, if necessary.
ch1_mpi 667 For more information on this, and how to apply and follow the GNU GPL, see
ch1_mpi 668 <http://www.gnu.org/licenses/>.
ch1_mpi 669
ch1_mpi 670 The GNU General Public License does not permit incorporating your program
ch1_mpi 671 into proprietary programs. If your program is a subroutine library, you
ch1_mpi 672 may consider it more useful to permit linking proprietary applications with
ch1_mpi 673 the library. If this is what you want to do, use the GNU Lesser General
ch1_mpi 674 Public License instead of this License. But first, please read
ch1_mpi 675 <http://www.gnu.org/philosophy/why-not-lgpl.html>.
