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