1.2 ! anton 14: @heading Preamble
! 15:
! 16: The GNU General Public License is a free, copyleft license for
! 17: software and other kinds of works.
1.1 anton 18:
1.2 ! anton 19: The licenses for most software and other practical works are designed
! 20: to take away your freedom to share and change the works. By contrast,
! 21: the GNU General Public License is intended to guarantee your freedom
! 22: to share and change all versions of a program---to make sure it remains
! 23: free software for all its users. We, the Free Software Foundation,
! 24: use the GNU General Public License for most of our software; it
! 25: applies also to any other work released this way by its authors. You
! 26: can apply it to your programs, too.
1.1 anton 27:
1.2 ! anton 28: When we speak of free software, we are referring to freedom, not
1.1 anton 29: price. Our General Public Licenses are designed to make sure that you
30: have the freedom to distribute copies of free software (and charge for
1.2 ! anton 31: them if you wish), that you receive source code or can get it if you
! 32: want it, that you can change the software or use pieces of it in new
! 33: free programs, and that you know you can do these things.
! 34:
! 35: To protect your rights, we need to prevent others from denying you
! 36: these rights or asking you to surrender the rights. Therefore, you
! 37: have certain responsibilities if you distribute copies of the
! 38: software, or if you modify it: responsibilities to respect the freedom
! 39: of others.
! 40:
! 41: For example, if you distribute copies of such a program, whether
! 42: gratis or for a fee, you must pass on to the recipients the same
! 43: freedoms that you received. You must make sure that they, too,
! 44: receive or can get the source code. And you must show them these
! 45: terms so they know their rights.
! 46:
! 47: Developers that use the GNU GPL protect your rights with two steps:
! 48: (1) assert copyright on the software, and (2) offer you this License
! 49: giving you legal permission to copy, distribute and/or modify it.
! 50:
! 51: For the developers' and authors' protection, the GPL clearly explains
! 52: that there is no warranty for this free software. For both users' and
! 53: authors' sake, the GPL requires that modified versions be marked as
! 54: changed, so that their problems will not be attributed erroneously to
! 55: authors of previous versions.
! 56:
! 57: Some devices are designed to deny users access to install or run
! 58: modified versions of the software inside them, although the
! 59: manufacturer can do so. This is fundamentally incompatible with the
! 60: aim of protecting users' freedom to change the software. The
! 61: systematic pattern of such abuse occurs in the area of products for
! 62: individuals to use, which is precisely where it is most unacceptable.
! 63: Therefore, we have designed this version of the GPL to prohibit the
! 64: practice for those products. If such problems arise substantially in
! 65: other domains, we stand ready to extend this provision to those
! 66: domains in future versions of the GPL, as needed to protect the
! 67: freedom of users.
! 68:
! 69: Finally, every program is threatened constantly by software patents.
! 70: States should not allow patents to restrict development and use of
! 71: software on general-purpose computers, but in those that do, we wish
! 72: to avoid the special danger that patents applied to a free program
! 73: could make it effectively proprietary. To prevent this, the GPL
! 74: assures that patents cannot be used to render the program non-free.
1.1 anton 75:
1.2 ! anton 76: The precise terms and conditions for copying, distribution and
1.1 anton 77: modification follow.

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

1.1 anton 661:
1.2 ! anton 662: If you develop a new program, and you want it to be of the greatest
1.1 anton 663: possible use to the public, the best way to achieve this is to make it
1.2 ! anton 664: free software which everyone can redistribute and change under these
! 665: terms.
1.1 anton 666:
1.2 ! anton 667: To do so, attach the following notices to the program. It is safest
1.1 anton 668: to attach them to the start of each source file to most effectively
1.2 ! anton 669: state the exclusion of warranty; and each file should have at least
1.1 anton 670: the ``copyright'' line and a pointer to where the full notice is found.
