  19     Everyone is permitted to copy and distribute verbatim copies of this license
  20     document, but changing it is not allowed.
  21   </p><h2><a name="gpl-3-preamble"></a>
  22     Preamble
  23   </h2><p>
  24     The <acronym class="acronym">GNU</acronym> General Public License is a free, copyleft
  25     license for software and other kinds of works.
  26   </p><p>
  27     The licenses for most software and other practical works are designed to
  28     take away your freedom to share and change the works.  By contrast, the
  29     <acronym class="acronym">GNU</acronym> General Public License is intended to guarantee your
  30     freedom to share and change all versions of a program—to make sure it
  31     remains free software for all its users.  We, the Free Software Foundation,
  32     use the <acronym class="acronym">GNU</acronym> General Public License for most of our
  33     software; it applies also to any other work released this way by its
  34     authors.  You can apply it to your programs, too.
  35   </p><p>
  36     When we speak of free software, we are referring to freedom, not price.  Our
  37     General Public Licenses are designed to make sure that you have the freedom
  38     to distribute copies of free software (and charge for them if you wish),
  39     that you receive source code or can get it if you want it, that you can
  40     change the software or use pieces of it in new free programs, and that you
  41     know you can do these things.
  42   </p><p>
  43     To protect your rights, we need to prevent others from denying you these
  44     rights or asking you to surrender the rights.  Therefore, you have certain
  45     responsibilities if you distribute copies of the software, or if you modify
  46     it: responsibilities to respect the freedom of others.
  47   </p><p>
  48     For example, if you distribute copies of such a program, whether gratis or
  49     for a fee, you must pass on to the recipients the same freedoms that you
  50     received.  You must make sure that they, too, receive or can get the source
  51     code.  And you must show them these terms so they know their rights.
  52   </p><p>
  53     Developers that use the <acronym class="acronym">GNU</acronym> <acronym class="acronym">GPL</acronym>
  54     protect your rights with two steps: (1) assert copyright on the software,
  55     and (2) offer you this License giving you legal permission to copy,
  56     distribute and/or modify it.
  57   </p><p>
  58     For the developers’ and authors’ protection, the
  59     <acronym class="acronym">GPL</acronym> clearly explains that there is no warranty for this
  60     free software.  For both users’ and authors’ sake, the
  61     <acronym class="acronym">GPL</acronym> requires that modified versions be marked as changed,
  62     so that their problems will not be attributed erroneously to authors of
  63     previous versions.
  64   </p><p>
  65     Some devices are designed to deny users access to install or run modified
  66     versions of the software inside them, although the manufacturer can do so.
  67     This is fundamentally incompatible with the aim of protecting users’
  68     freedom to change the software.  The systematic pattern of such abuse occurs
  69     in the area of products for individuals to use, which is precisely where it
  70     is most unacceptable.  Therefore, we have designed this version of the
  71     <acronym class="acronym">GPL</acronym> to prohibit the practice for those products.  If such
  72     problems arise substantially in other domains, we stand ready to extend this
  73     provision to those domains in future versions of the <acronym class="acronym">GPL</acronym>,
  74     as needed to protect the freedom of users.
  75   </p><p>
  76     Finally, every program is threatened constantly by software patents.  States
  77     should not allow patents to restrict development and use of software on
  78     general-purpose computers, but in those that do, we wish to avoid the
  79     special danger that patents applied to a free program could make it
  80     effectively proprietary.  To prevent this, the <acronym class="acronym">GPL</acronym>
  81     assures that patents cannot be used to render the program non-free.
  82   </p><p>
  83     The precise terms and conditions for copying, distribution and modification
  84     follow.
  85   </p><h2><a name="id688629"></a>
  86     TERMS AND CONDITIONS
  87   </h2><h2><a name="gpl-3-definitions"></a>
  88     0. Definitions.
  89   </h2><p>
  90     “This License” refers to version 3 of the <acronym class="acronym">GNU</acronym>
  91     General Public License.
  92   </p><p>
  93     “Copyright” also means copyright-like laws that apply to other
  94     kinds of works, such as semiconductor masks.
  95   </p><p>
  96     “The Program” refers to any copyrightable work licensed under
  97     this License.  Each licensee is addressed as “you”.
  98     “Licensees” and “recipients” may be individuals or
  99     organizations.
 100   </p><p>
 101     To “modify” a work means to copy from or adapt all or part of
 102     the work in a fashion requiring copyright permission, other than the making
 103     of an exact copy.  The resulting work is called a “modified
 104     version” of the earlier work or a work “based on” the
 105     earlier work.
 106   </p><p>
 107     A “covered work” means either the unmodified Program or a work
 108     based on the Program.
 109   </p><p>
 110     To “propagate” a work means to do anything with it that, without
 111     permission, would make you directly or secondarily liable for infringement
 112     under applicable copyright law, except executing it on a computer or
 113     modifying a private copy.  Propagation includes copying, distribution (with
 114     or without modification), making available to the public, and in some
 115     countries other activities as well.
 116   </p><p>
 117     To “convey” a work means any kind of propagation that enables
 118     other parties to make or receive copies.  Mere interaction with a user
 119     through a computer network, with no transfer of a copy, is not conveying.
 120   </p><p>
 121     An interactive user interface displays “Appropriate Legal
 122     Notices” to the extent that it includes a convenient and prominently
 123     visible feature that (1) displays an appropriate copyright notice, and (2)
 124     tells the user that there is no warranty for the work (except to the extent
 125     that warranties are provided), that licensees may convey the work under this
 126     License, and how to view a copy of this License.  If the interface presents
 127     a list of user commands or options, such as a menu, a prominent item in the
 128     list meets this criterion.
 129   </p><h2><a name="SourceCode"></a>
 130     1. Source Code.
 131   </h2><p>
 132     The “source code” for a work means the preferred form of the
 133     work for making modifications to it.  “Object code” means any
 134     non-source form of a work.
 135   </p><p>
 136     A “Standard Interface” means an interface that either is an
 137     official standard defined by a recognized standards body, or, in the case of
 138     interfaces specified for a particular programming language, one that is
 139     widely used among developers working in that language.
 140   </p><p>
 141     The “System Libraries” of an executable work include anything,
 142     other than the work as a whole, that (a) is included in the normal form of
 143     packaging a Major Component, but which is not part of that Major Component,
 144     and (b) serves only to enable use of the work with that Major Component, or
 145     to implement a Standard Interface for which an implementation is available
 146     to the public in source code form.  A “Major Component”, in this
 147     context, means a major essential component (kernel, window system, and so
 148     on) of the specific operating system (if any) on which the executable work
 149     runs, or a compiler used to produce the work, or an object code interpreter
 150     used to run it.
 151   </p><p>
 152     The “Corresponding Source” for a work in object code form means
 153     all the source code needed to generate, install, and (for an executable
 154     work) run the object code and to modify the work, including scripts to
 155     control those activities.  However, it does not include the work’s
 156     System Libraries, or general-purpose tools or generally available free
 157     programs which are used unmodified in performing those activities but which
 158     are not part of the work.  For example, Corresponding Source includes
 159     interface definition files associated with source files for the work, and
 160     the source code for shared libraries and dynamically linked subprograms that
 161     the work is specifically designed to require, such as by intimate data
 162     communication or control flow between those subprograms and other parts of
 163     the work.
 164   </p><p>
 165     The Corresponding Source need not include anything that users can regenerate
 166     automatically from other parts of the Corresponding Source.
 167   </p><p>
 168     The Corresponding Source for a work in source code form is that same work.
 169   </p><h2><a name="BasicPermissions"></a>
 170     2. Basic Permissions.
 171   </h2><p>
 172     All rights granted under this License are granted for the term of copyright
 173     on the Program, and are irrevocable provided the stated conditions are met.
 174     This License explicitly affirms your unlimited permission to run the
 175     unmodified Program.  The output from running a covered work is covered by
 176     this License only if the output, given its content, constitutes a covered
 177     work.  This License acknowledges your rights of fair use or other
 178     equivalent, as provided by copyright law.
 179   </p><p>
 180     You may make, run and propagate covered works that you do not convey,
 181     without conditions so long as your license otherwise remains in force.  You
 182     may convey covered works to others for the sole purpose of having them make
 183     modifications exclusively for you, or provide you with facilities for
 184     running those works, provided that you comply with the terms of this License
 185     in conveying all material for which you do not control copyright.  Those
 186     thus making or running the covered works for you must do so exclusively on
 187     your behalf, under your direction and control, on terms that prohibit them
 188     from making any copies of your copyrighted material outside their
 189     relationship with you.
 190   </p><p>
 191     Conveying under any other circumstances is permitted solely under the
 192     conditions stated below.  Sublicensing is not allowed; section 10 makes it
 193     unnecessary.
 194   </p><h2><a name="Protecting"></a>
 195     3. Protecting Users’ Legal Rights From Anti-Circumvention Law.
 196   </h2><p>
 197     No covered work shall be deemed part of an effective technological measure
 198     under any applicable law fulfilling obligations under article 11 of the WIPO
 199     copyright treaty adopted on 20 December 1996, or similar laws prohibiting or
 200     restricting circumvention of such measures.
 201   </p><p>
 202     When you convey a covered work, you waive any legal power to forbid
 203     circumvention of technological measures to the extent such circumvention is
 204     effected by exercising rights under this License with respect to the covered
 205     work, and you disclaim any intention to limit operation or modification of
 206     the work as a means of enforcing, against the work’s users, your or
 207     third parties’ legal rights to forbid circumvention of technological
 208     measures.
 209   </p><h2><a name="ConveyingVerbatim"></a>
 210     4. Conveying Verbatim Copies.
 211   </h2><p>
 212     You may convey verbatim copies of the Program’s source code as you
 213     receive it, in any medium, provided that you conspicuously and appropriately
 214     publish on each copy an appropriate copyright notice; keep intact all
 215     notices stating that this License and any non-permissive terms added in
 216     accord with section 7 apply to the code; keep intact all notices of the
 217     absence of any warranty; and give all recipients a copy of this License
 218     along with the Program.
 219   </p><p>
 220     You may charge any price or no price for each copy that you convey, and you
 221     may offer support or warranty protection for a fee.
 222   </p><h2><a name="ConveyingModified"></a>
 223     5. Conveying Modified Source Versions.
 224   </h2><p>
 225     You may convey a work based on the Program, or the modifications to produce
 226     it from the Program, in the form of source code under the terms of section
 227     4, provided that you also meet all of these conditions:
 228   </p><div class="orderedlist"><ol class="orderedlist" type="a"><li class="listitem"><p>
 229         The work must carry prominent notices stating that you modified it, and
 230         giving a relevant date.
 231       </p></li><li class="listitem"><p>
 232         The work must carry prominent notices stating that it is released under
 233         this License and any conditions added under section 7.  This requirement
 234         modifies the requirement in section 4 to “keep intact all
 235         notices”.
 236       </p></li><li class="listitem"><p>
 237         You must license the entire work, as a whole, under this License to
 238         anyone who comes into possession of a copy.  This License will therefore
 239         apply, along with any applicable section 7 additional terms, to the
 240         whole of the work, and all its parts, regardless of how they are
 241         packaged.  This License gives no permission to license the work in any
 242         other way, but it does not invalidate such permission if you have
 243         separately received it.
 244       </p></li><li class="listitem"><p>
 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 need
 248         not make them do so.
 249       </p></li></ol></div><p>
 250     A compilation of a covered work with other separate and independent works,
 251     which are not by their nature extensions of the covered work, and which are
 252     not combined with it such as to form a larger program, in or on a volume of
 253     a storage or distribution medium, is called an “aggregate” if
 254     the compilation and its resulting copyright are not used to limit the access
 255     or legal rights of the compilation’s users beyond what the individual works
 256     permit.  Inclusion of a covered work in an aggregate does not cause
 257     this License to apply to the other parts of the aggregate.
 258   </p><h2><a name="ConveyingNonSource"></a>
 259     6. Conveying Non-Source Forms.
 260   </h2><p>
 261     You may convey a covered work in object code form under the terms of
 262     sections 4 and 5, provided that you also convey the machine-readable
 263     Corresponding Source under the terms of this License, in one of these ways:
 264   </p><div class="orderedlist"><ol class="orderedlist" type="a"><li class="listitem"><p>
 265         Convey the object code in, or embodied in, a physical product (including
 266         a physical distribution medium), accompanied by the Corresponding Source
 267         fixed on a durable physical medium customarily used for software
 268         interchange.
 269       </p></li><li class="listitem"><p>
 270         Convey the object code in, or embodied in, a physical product (including
 271         a physical distribution medium), accompanied by a written offer, valid
 272         for at least three years and valid for as long as you offer spare parts
 273         or customer support for that product model, to give anyone who possesses
 274         the object code either (1) a copy of the Corresponding Source for all
 275         the software in the product that is covered by this License, on a
 276         durable physical medium customarily used for software interchange, for a
 277         price no more than your reasonable cost of physically performing this
 278         conveying of source, or (2) access to copy the Corresponding Source from
 279         a network server at no charge.
 280       </p></li><li class="listitem"><p>
 281         Convey individual copies of the object code with a copy of the written
 282         offer to provide the Corresponding Source.  This alternative is allowed
 283         only occasionally and noncommercially, and only if you received the
 284         object code with such an offer, in accord with subsection 6b.
 285       </p></li><li class="listitem"><p>
 286         Convey the object code by offering access from a designated place
 287         (gratis or for a charge), and offer equivalent access to the
 288         Corresponding Source in the same way through the same place at no
 289         further charge.  You need not require recipients to copy the
 290         Corresponding Source along with the object code.  If the place to copy
 291         the object code is a network server, the Corresponding Source may be on
 292         a different server (operated by you or a third party) that supports
 293         equivalent copying facilities, provided you maintain clear directions
 294         next to the object code saying where to find the Corresponding Source.
 295         Regardless of what server hosts the Corresponding Source, you remain
 296         obligated to ensure that it is available for as long as needed to
 297         satisfy these requirements.
 298       </p></li><li class="listitem"><p>
 299         Convey the object code using peer-to-peer transmission, provided you
 300         inform other peers where the object code and Corresponding Source of the
 301         work are being offered to the general public at no charge under
 302         subsection 6d.
 303       </p></li></ol></div><p>
 304     A separable portion of the object code, whose source code is excluded from
 305     the Corresponding Source as a System Library, need not be included in
 306     conveying the object code work.
 307   </p><p>
 308     A “User Product” is either (1) a “consumer product”,
 309     which means any tangible personal property which is normally used for
 310     personal, family, or household purposes, or (2) anything designed or sold
 311     for incorporation into a dwelling.  In determining whether a product is a
 312     consumer product, doubtful cases shall be resolved in favor of coverage.
 313     For a particular product received by a particular user, “normally
 314     used” refers to a typical or common use of that class of product,
 315     regardless of the status of the particular user or of the way in which the
 316     particular user actually uses, or expects or is expected to use, the
 317     product.  A product is a consumer product regardless of whether the product
 318     has substantial commercial, industrial or non-consumer uses, unless such
 319     uses represent the only significant mode of use of the product.
 320   </p><p>
 321     “Installation Information” for a User Product means any methods,
 322     procedures, authorization keys, or other information required to install and
 323     execute modified versions of a covered work in that User Product from a
 324     modified version of its Corresponding Source.  The information must suffice
 325     to ensure that the continued functioning of the modified object code is in
 326     no case prevented or interfered with solely because modification has been
 327     made.
 328   </p><p>
 329     If you convey an object code work under this section in, or with, or
 330     specifically for use in, a User Product, and the conveying occurs as part of
 331     a transaction in which the right of possession and use of the User Product
 332     is transferred to the recipient in perpetuity or for a fixed term
 333     (regardless of how the transaction is characterized), the Corresponding
 334     Source conveyed under this section must be accompanied by the Installation
 335     Information.  But this requirement does not apply if neither you nor any
 336     third party retains the ability to install modified object code on the User
 337     Product (for example, the work has been installed in
 338     <acronym class="acronym">ROM</acronym>).
 339   </p><p>
 340     The requirement to provide Installation Information does not include a
 341     requirement to continue to provide support service, warranty, or updates for
 342     a work that has been modified or installed by the recipient, or for the User
 343     Product in which it has been modified or installed.  Access to a network may
 344     be denied when the modification itself materially and adversely affects the
 345     operation of the network or violates the rules and protocols for
 346     communication across the network.
 347   </p><p>
 348     Corresponding Source conveyed, and Installation Information provided, in
 349     accord with this section must be in a format that is publicly documented
 350     (and with an implementation available to the public in source code form),
 351     and must require no special password or key for unpacking, reading or
 352     copying.

 356      “Additional permissions” are terms that supplement the terms of
 357      this License by making exceptions from one or more of its conditions.
 358      Additional permissions that are applicable to the entire Program shall be
 359      treated as though they were included in this License, to the extent that
 360      they are valid under applicable law.  If additional permissions apply only
 361      to part of the Program, that part may be used separately under those
 362      permissions, but the entire Program remains governed by this License
 363      without regard to the additional permissions.
 364    </p><p>
 365      When you convey a copy of a covered work, you may at your option remove any
 366      additional permissions from that copy, or from any part of it.  (Additional
 367      permissions may be written to require their own removal in certain cases
 368      when you modify the work.)  You may place additional permissions on
 369      material, added by you to a covered work, for which you have or can give
 370      appropriate copyright permission.
 371    </p><p>
 372      Notwithstanding any other provision of this License, for material you add
 373      to a covered work, you may (if authorized by the copyright holders of that
 374      material) supplement the terms of this License with terms:
 375    </p><div class="orderedlist"><ol class="orderedlist" type="a"><li class="listitem"><p>
 376          Disclaiming warranty or limiting liability differently from the terms
 377          of sections 15 and 16 of this License; or
 378        </p></li><li class="listitem"><p>
 379          Requiring preservation of specified reasonable legal notices or author
 380          attributions in that material or in the Appropriate Legal Notices
 381          displayed by works containing it; or
 382        </p></li><li class="listitem"><p>
 383          Prohibiting misrepresentation of the origin of that material, or
 384          requiring that modified versions of such material be marked in
 385          reasonable ways as different from the original version; or
 386        </p></li><li class="listitem"><p>
 387          Limiting the use for publicity purposes of names of licensors or
 388          authors of the material; or
 389        </p></li><li class="listitem"><p>
 390          Declining to grant rights under trademark law for use of some trade
 391          names, trademarks, or service marks; or
 392        </p></li><li class="listitem"><p>
 393          Requiring indemnification of licensors and authors of that material by
 394          anyone who conveys the material (or modified versions of it) with
 395          contractual assumptions of liability to the recipient, for any
 396          liability that these contractual assumptions directly impose on those
 397          licensors and authors.
 398        </p></li></ol></div><p>
 399      All other non-permissive additional terms are considered “further
 400      restrictions” within the meaning of section 10.  If the Program as
 401      you received it, or any part of it, contains a notice stating that it is
 402      governed by this License along with a term that is a further restriction,
 403      you may remove that term.  If a license document contains a further
 404      restriction but permits relicensing or conveying under this License, you
 405      may add to a covered work material governed by the terms of that license
 406      document, provided that the further restriction does not survive such
 407      relicensing or conveying.
 408    </p><p>
 409      If you add terms to a covered work in accord with this section, you must
 410      place, in the relevant source files, a statement of the additional terms
 411      that apply to those files, or a notice indicating where to find the
 412      applicable terms.
 413    </p><p>
 414      Additional terms, permissive or non-permissive, may be stated in the form
 415      of a separately written license, or stated as exceptions; the above
 416      requirements apply either way.
 417    </p><h2><a name="gpl-3-termination"></a>
 418      8. Termination.
 419    </h2><p>
 420      You may not propagate or modify a covered work except as expressly provided
 421      under this License.  Any attempt otherwise to propagate or modify it is
 422      void, and will automatically terminate your rights under this License
 423      (including any patent licenses granted under the third paragraph of section
 424      11).
 425    </p><p>
 426      However, if you cease all violation of this License, then your license from
 427      a particular copyright holder is reinstated (a) provisionally, unless and
 428      until the copyright holder explicitly and finally terminates your license,
 429      and (b) permanently, if the copyright holder fails to notify you of the
 430      violation by some reasonable means prior to 60 days after the cessation.
 431    </p><p>
 432      Moreover, your license from a particular copyright holder is reinstated
 433      permanently if the copyright holder notifies you of the violation by some
 434      reasonable means, this is the first time you have received notice of
 435      violation of this License (for any work) from that copyright holder, and
 436      you cure the violation prior to 30 days after your receipt of the notice.
 437    </p><p>
 438      Termination of your rights under this section does not terminate the
 439      licenses of parties who have received copies or rights from you under this
 440      License.  If your rights have been terminated and not permanently
 441      reinstated, you do not qualify to receive new licenses for the same
 442      material under section 10.
 443    </p><h2><a name="AcceptanceNotRequired"></a>
 444      9. Acceptance Not Required for Having Copies.
 445    </h2><p>
 446      You are not required to accept this License in order to receive or run a
 447      copy of the Program.  Ancillary propagation of a covered work occurring
 448      solely as a consequence of using peer-to-peer transmission to receive a
 449      copy likewise does not require acceptance.  However, nothing other than
 450      this License grants you permission to propagate or modify any covered work.
 451      These actions infringe copyright if you do not accept this License.
 452      Therefore, by modifying or propagating a covered work, you indicate your
 453      acceptance of this License to do so.
 454    </p><h2><a name="AutomaticDownstream"></a>
 455      10. Automatic Licensing of Downstream Recipients.
 456    </h2><p>
 457      Each time you convey a covered work, the recipient automatically receives a
 458      license from the original licensors, to run, modify and propagate that
 459      work, subject to this License.  You are not responsible for enforcing
 460      compliance by third parties with this License.
 461    </p><p>
 462      An “entity transaction” is a transaction transferring control
 463      of an organization, or substantially all assets of one, or subdividing an
 464      organization, or merging organizations.  If propagation of a covered work
 465      results from an entity transaction, each party to that transaction who
 466      receives a copy of the work also receives whatever licenses to the work the
 467      party’s predecessor in interest had or could give under the previous
 468      paragraph, plus a right to possession of the Corresponding Source of the
 469      work from the predecessor in interest, if the predecessor has it or can get
 470      it with reasonable efforts.
 471    </p><p>
 472      You may not impose any further restrictions on the exercise of the rights
 473      granted or affirmed under this License.  For example, you may not impose a
 474      license fee, royalty, or other charge for exercise of rights granted under
 475      this License, and you may not initiate litigation (including a cross-claim
 476      or counterclaim in a lawsuit) alleging that any patent claim is infringed
 477      by making, using, selling, offering for sale, or importing the Program or
 478      any portion of it.
 479    </p><h2><a name="Patents"></a>
 480     11. Patents.
 481   </h2><p>
 482     A “contributor” is a copyright holder who authorizes use under
 483     this License of the Program or a work on which the Program is based.  The
 484     work thus licensed is called the contributor’s “contributor
 485     version”.
 486   </p><p>
 487     A contributor’s “essential patent claims” are all patent
 488     claims owned or controlled by the contributor, whether already acquired or
 489     hereafter acquired, that would be infringed by some manner, permitted by
 490     this License, of making, using, or selling its contributor version, but do
 491     not include claims that would be infringed only as a consequence of further
 492     modification of the contributor version.  For purposes of this definition,
 493     “control” includes the right to grant patent sublicenses in a
 494     manner consistent with the requirements of this License.
 495   </p><p>
 496     Each contributor grants you a non-exclusive, worldwide, royalty-free patent
 497     license under the contributor’s essential patent claims, to make, use,
 498     sell, offer for sale, import and otherwise run, modify and propagate the
 499     contents of its contributor version.
 500   </p><p>
 501     In the following three paragraphs, a “patent license” is any
 502     express agreement or commitment, however denominated, not to enforce a
 503     patent (such as an express permission to practice a patent or covenant not
 504     to sue for patent infringement).  To “grant” such a patent
 505     license to a party means to make such an agreement or commitment not to
 506     enforce a patent against the party.
 507   </p><p>
 508     If you convey a covered work, knowingly relying on a patent license, and the
 509     Corresponding Source of the work is not available for anyone to copy, free
 510     of charge and under the terms of this License, through a publicly available
 511     network server or other readily accessible means, then you must either (1)
 512     cause the Corresponding Source to be so available, or (2) arrange to deprive
 513     yourself of the benefit of the patent license for this particular work, or
 514     (3) arrange, in a manner consistent with the requirements of this License,
 515     to extend the patent license to downstream recipients.  “Knowingly
 516     relying” means you have actual knowledge that, but for the patent
 517     license, your conveying the covered work in a country, or your
 518     recipient’s use of the covered work in a country, would infringe one
 519     or more identifiable patents in that country that you have reason to believe
 520     are valid.
 521   </p><p>
 522     If, pursuant to or in connection with a single transaction or arrangement,
 523     you convey, or propagate by procuring conveyance of, a covered work, and
 524     grant a patent license to some of the parties receiving the covered work
 525     authorizing them to use, propagate, modify or convey a specific copy of the
 526     covered work, then the patent license you grant is automatically extended to
 527     all recipients of the covered work and works based on it.
 528   </p><p>
 529     A patent license is “discriminatory” if it does not include
 530     within the scope of its coverage, prohibits the exercise of, or is
 531     conditioned on the non-exercise of one or more of the rights that are
 532     specifically granted under this License.  You may not convey a covered work
 533     if you are a party to an arrangement with a third party that is in the
 534     business of distributing software, under which you make payment to the third
 535     party based on the extent of your activity of conveying the work, and under
 536     which the third party grants, to any of the parties who would receive the
 537     covered work from you, a discriminatory patent license (a) in connection
 538     with copies of the covered work conveyed by you (or copies made from those
 539     copies), or (b) primarily for and in connection with specific products or
 540     compilations that contain the covered work, unless you entered into that
 541     arrangement, or that patent license was granted, prior to 28 March 2007.
 542   </p><p>
 543     Nothing in this License shall be construed as excluding or limiting any
 544     implied license or other defenses to infringement that may otherwise be
 545     available to you under applicable patent law.
 546   </p><h2><a name="NoSurrender"></a>
 547     12. No Surrender of Others’ Freedom.
 548   </h2><p>
 549     If conditions are imposed on you (whether by court order, agreement or
 550     otherwise) that contradict the conditions of this License, they do not
 551     excuse you from the conditions of this License.  If you cannot convey a
 552     covered work so as to satisfy simultaneously your obligations under this
 553     License and any other pertinent obligations, then as a consequence you may
 554     not convey it at all.  For example, if you agree to terms that obligate you
 555     to collect a royalty for further conveying from those to whom you convey the
 556     Program, the only way you could satisfy both those terms and this License
 557     would be to refrain entirely from conveying the Program.

 559     13. Use with the <acronym class="acronym">GNU</acronym> Affero General Public License.
 560   </h2><p>
 561     Notwithstanding any other provision of this License, you have permission to
 562     link or combine any covered work with a work licensed under version 3 of the
 563     <acronym class="acronym">GNU</acronym> Affero General Public License into a single combined
 564     work, and to convey the resulting work.  The terms of this License will
 565     continue to apply to the part which is the covered work, but the special
 566     requirements of the <acronym class="acronym">GNU</acronym> Affero General Public License,
 567     section 13, concerning interaction through a network will apply to the
 568     combination as such.
 569   </p><h2><a name="RevisedVersions"></a>
 570     14. Revised Versions of this License.
 571   </h2><p>
 572     The Free Software Foundation may publish revised and/or new versions of the
 573     <acronym class="acronym">GNU</acronym> General Public License from time to time.  Such new
 574     versions will be similar in spirit to the present version, but may differ in
 575     detail to address new problems or concerns.
 576   </p><p>
 577     Each version is given a distinguishing version number.  If the Program
 578     specifies that a certain numbered version of the <acronym class="acronym">GNU</acronym>
 579     General Public License “or any later version” applies to it, you
 580     have the option of following the terms and conditions either of that
 581     numbered version or of any later version published by the Free Software
 582     Foundation.  If the Program does not specify a version number of the
 583     <acronym class="acronym">GNU</acronym> General Public License, you may choose any version
 584     ever published by the Free Software Foundation.
 585   </p><p>
 586     If the Program specifies that a proxy can decide which future versions of
 587     the <acronym class="acronym">GNU</acronym> General Public License can be used, that
 588     proxy’s public statement of acceptance of a version permanently
 589     authorizes you to choose that version for the Program.
 590   </p><p>
 591     Later license versions may give you additional or different permissions.
 592     However, no additional obligations are imposed on any author or copyright
 593     holder as a result of your choosing to follow a later version.
 594   </p><h2><a name="WarrantyDisclaimer"></a>
 595     15. Disclaimer of Warranty.
 596   </h2><p>
 597     THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
 598     LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR

 600     ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
 601     IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
 602     THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH

 612     OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
 613     OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD

 620     If the disclaimer of warranty and limitation of liability provided above
 621     cannot be given local legal effect according to their terms, reviewing
 622     courts shall apply local law that most closely approximates an absolute

 629     How to Apply These Terms to Your New Programs
 630   </h2><p>
 631     If you develop a new program, and you want it to be of the greatest possible
 632     use to the public, the best way to achieve this is to make it free software
 633     which everyone can redistribute and change under these terms.
 634   </p><p>
 635     To do so, attach the following notices to the program.  It is safest to
 636     attach them to the start of each source file to most effectively state the
 637     exclusion of warranty; and each file should have at least the
 638     “copyright” line and a pointer to where the full notice is
 639     found.
 640   </p><pre class="screen">

 645 it under the terms of the <acronym class="acronym">GNU</acronym> General Public License as published by

 650 but WITHOUT ANY WARRANTY; without even the implied warranty of

 653
 654 You should have received a copy of the <acronym class="acronym">GNU</acronym> General Public License
 655 along with this program.  If not, see <a class="link" href="http://www.gnu.org/licenses/" target="_top">http://www.gnu.org/licenses/</a>.

 657     Also add information on how to contact you by electronic and paper mail.
 658   </p><p>

 666   </pre><p>
 667     The hypothetical commands ‘<code class="literal">show w</code>’ and
 668     ‘<code class="literal">show c</code>’ should show the appropriate parts of
 669     the General Public License.  Of course, your program’s commands might be
 670     different; for a GUI interface, you would use an “about box”.
 671   </p><p>
 672     You should also get your employer (if you work as a programmer) or school,
