    35                      GNU AFFERO GENERAL PUBLIC LICENSE
    36                         Version 3, 19 November 2007
    37  
    38   Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
    39   Everyone is permitted to copy and distribute verbatim copies
    40   of this license document, but changing it is not allowed.
    41  
    42                              Preamble
    43  
    44    The GNU Affero General Public License is a free, copyleft license for
    45  software and other kinds of works, specifically designed to ensure
    46  cooperation with the community in the case of network server software.
    47  
    48    The licenses for most software and other practical works are designed
    49  to take away your freedom to share and change the works.  By contrast,
    50  our General Public Licenses are intended to guarantee your freedom to
    51  share and change all versions of a program--to make sure it remains free
    52  software for all its users.
    53  
    54    When we speak of free software, we are referring to freedom, not
    55  price.  Our General Public Licenses are designed to make sure that you
    56  have the freedom to distribute copies of free software (and charge for
    57  them if you wish), that you receive source code or can get it if you
    58  want it, that you can change the software or use pieces of it in new
    59  free programs, and that you know you can do these things.
    60  
    61    Developers that use our General Public Licenses protect your rights
    62  with two steps: (1) assert copyright on the software, and (2) offer
    63  you this License which gives you legal permission to copy, distribute
    64  and/or modify the software.
    65  
    66    A secondary benefit of defending all users' freedom is that
    67  improvements made in alternate versions of the program, if they
    68  receive widespread use, become available for other developers to
    69  incorporate.  Many developers of free software are heartened and
    70  encouraged by the resulting cooperation.  However, in the case of
    71  software used on network servers, this result may fail to come about.
    72  The GNU General Public License permits making a modified version and
    73  letting the public access it on a server without ever releasing its
    74  source code to the public.
    75  
    76    The GNU Affero General Public License is designed specifically to
    77  ensure that, in such cases, the modified source code becomes available
    78  to the community.  It requires the operator of a network server to
    79  provide the source code of the modified version running there to the
    80  users of that server.  Therefore, public use of a modified version, on
    81  a publicly accessible server, gives the public access to the source
    82  code of the modified version.
    83  
    84    An older license, called the Affero General Public License and
    85  published by Affero, was designed to accomplish similar goals.  This is
    86  a different license, not a version of the Affero GPL, but Affero has
    87  released a new version of the Affero GPL which permits relicensing under
    88  this license.
    89  
    90    The precise terms and conditions for copying, distribution and
    91  modification follow.
    92  
    93                         TERMS AND CONDITIONS
    94  
    95    0. Definitions.
    96  
    97    "This License" refers to version 3 of the GNU Affero General Public License.
    98  
    99    "Copyright" also means copyright-like laws that apply to other kinds of
   100  works, such as semiconductor masks.
   101  
   102    "The Program" refers to any copyrightable work licensed under this
   103  License.  Each licensee is addressed as "you".  "Licensees" and
   104  "recipients" may be individuals or organizations.
   105  
   106    To "modify" a work means to copy from or adapt all or part of the work
   107  in a fashion requiring copyright permission, other than the making of an
   108  exact copy.  The resulting work is called a "modified version" of the
   109  earlier work or a work "based on" the earlier work.
   110  
   111    A "covered work" means either the unmodified Program or a work based
   112  on the Program.
   113  
   114    To "propagate" a work means to do anything with it that, without
   115  permission, would make you directly or secondarily liable for
   116  infringement under applicable copyright law, except executing it on a
   117  computer or modifying a private copy.  Propagation includes copying,
   118  distribution (with or without modification), making available to the
   119  public, and in some countries other activities as well.
   120  
   121    To "convey" a work means any kind of propagation that enables other
   122  parties to make or receive copies.  Mere interaction with a user through
   123  a computer network, with no transfer of a copy, is not conveying.
   124  
   125    An interactive user interface displays "Appropriate Legal Notices"
   126  to the extent that it includes a convenient and prominently visible
   127  feature that (1) displays an appropriate copyright notice, and (2)
   128  tells the user that there is no warranty for the work (except to the
   129  extent that warranties are provided), that licensees may convey the
   130  work under this License, and how to view a copy of this License.  If
   131  the interface presents a list of user commands or options, such as a
   132  menu, a prominent item in the list meets this criterion.
   133  
   134    1. Source Code.
   135  
   136    The "source code" for a work means the preferred form of the work
   137  for making modifications to it.  "Object code" means any non-source
   138  form of a work.
   139  
   140    A "Standard Interface" means an interface that either is an official
   141  standard defined by a recognized standards body, or, in the case of
   142  interfaces specified for a particular programming language, one that
   143  is widely used among developers working in that language.
   144  
   145    The "System Libraries" of an executable work include anything, other
   146  than the work as a whole, that (a) is included in the normal form of
   147  packaging a Major Component, but which is not part of that Major
   148  Component, and (b) serves only to enable use of the work with that
   149  Major Component, or to implement a Standard Interface for which an
   150  implementation is available to the public in source code form.  A
   151  "Major Component", in this context, means a major essential component
   152  (kernel, window system, and so on) of the specific operating system
   153  (if any) on which the executable work runs, or a compiler used to
   154  produce the work, or an object code interpreter used to run it.
   155  
   156    The "Corresponding Source" for a work in object code form means all
   157  the source code needed to generate, install, and (for an executable
   158  work) run the object code and to modify the work, including scripts to
   159  control those activities.  However, it does not include the work's
   160  System Libraries, or general-purpose tools or generally available free
   161  programs which are used unmodified in performing those activities but
   162  which are not part of the work.  For example, Corresponding Source
   163  includes interface definition files associated with source files for
   164  the work, and the source code for shared libraries and dynamically
   165  linked subprograms that the work is specifically designed to require,
   166  such as by intimate data communication or control flow between those
   167  subprograms and other parts of the work.
   168  
   169    The Corresponding Source need not include anything that users
   170  can regenerate automatically from other parts of the Corresponding
   171  Source.
   172  
   173    The Corresponding Source for a work in source code form is that
   174  same work.
   175  
   176    2. Basic Permissions.
   177  
   178    All rights granted under this License are granted for the term of
   179  copyright on the Program, and are irrevocable provided the stated
   180  conditions are met.  This License explicitly affirms your unlimited
   181  permission to run the unmodified Program.  The output from running a
   182  covered work is covered by this License only if the output, given its
   183  content, constitutes a covered work.  This License acknowledges your
   184  rights of fair use or other equivalent, as provided by copyright law.
   185  
   186    You may make, run and propagate covered works that you do not
   187  convey, without conditions so long as your license otherwise remains
   188  in force.  You may convey covered works to others for the sole purpose
   189  of having them make modifications exclusively for you, or provide you
   190  with facilities for running those works, provided that you comply with
   191  the terms of this License in conveying all material for which you do
   192  not control copyright.  Those thus making or running the covered works
   193  for you must do so exclusively on your behalf, under your direction
   194  and control, on terms that prohibit them from making any copies of
   195  your copyrighted material outside their relationship with you.
   196  
   197    Conveying under any other circumstances is permitted solely under
   198  the conditions stated below.  Sublicensing is not allowed; section 10
   199  makes it unnecessary.
   200  
   201    3. Protecting Users' Legal Rights From Anti-Circumvention Law.
   202  
   203    No covered work shall be deemed part of an effective technological
   204  measure under any applicable law fulfilling obligations under article
   205  11 of the WIPO copyright treaty adopted on 20 December 1996, or
   206  similar laws prohibiting or restricting circumvention of such
   207  measures.
   208  
   209    When you convey a covered work, you waive any legal power to forbid
   210  circumvention of technological measures to the extent such circumvention
   211  is effected by exercising rights under this License with respect to
   212  the covered work, and you disclaim any intention to limit operation or
   213  modification of the work as a means of enforcing, against the work's
   214  users, your or third parties' legal rights to forbid circumvention of
   215  technological measures.
   216  
   217    4. Conveying Verbatim Copies.
   218  
   219    You may convey verbatim copies of the Program's source code as you
   220  receive it, in any medium, provided that you conspicuously and
   221  appropriately publish on each copy an appropriate copyright notice;
   222  keep intact all notices stating that this License and any
   223  non-permissive terms added in accord with section 7 apply to the code;
   224  keep intact all notices of the absence of any warranty; and give all
   225  recipients a copy of this License along with the Program.
   226  
   227    You may charge any price or no price for each copy that you convey,
   228  and you may offer support or warranty protection for a fee.
   229  
   230    5. Conveying Modified Source Versions.
   231  
   232    You may convey a work based on the Program, or the modifications to
   233  produce it from the Program, in the form of source code under the
   234  terms of section 4, provided that you also meet all of these conditions:
   235  
   236      a) The work must carry prominent notices stating that you modified
   237      it, and giving a relevant date.
   238  
   239      b) The work must carry prominent notices stating that it is
   240      released under this License and any conditions added under section
   241      7.  This requirement modifies the requirement in section 4 to
   242      "keep intact all notices".
   243  
   244      c) You must license the entire work, as a whole, under this
   245      License to anyone who comes into possession of a copy.  This
   246      License will therefore apply, along with any applicable section 7
   247      additional terms, to the whole of the work, and all its parts,
   248      regardless of how they are packaged.  This License gives no
   249      permission to license the work in any other way, but it does not
   250      invalidate such permission if you have separately received it.
   251  
   252      d) If the work has interactive user interfaces, each must display
   253      Appropriate Legal Notices; however, if the Program has interactive
   254      interfaces that do not display Appropriate Legal Notices, your
   255      work need not make them do so.
   256  
   257    A compilation of a covered work with other separate and independent
   258  works, which are not by their nature extensions of the covered work,
   259  and which are not combined with it such as to form a larger program,
   260  in or on a volume of a storage or distribution medium, is called an
   261  "aggregate" if the compilation and its resulting copyright are not
   262  used to limit the access or legal rights of the compilation's users
   263  beyond what the individual works permit.  Inclusion of a covered work
   264  in an aggregate does not cause this License to apply to the other
   265  parts of the aggregate.
   266  
   267    6. Conveying Non-Source Forms.
   268  
   269    You may convey a covered work in object code form under the terms
   270  of sections 4 and 5, provided that you also convey the
   271  machine-readable Corresponding Source under the terms of this License,
   272  in one of these ways:
   273  
   274      a) Convey the object code in, or embodied in, a physical product
   275      (including a physical distribution medium), accompanied by the
   276      Corresponding Source fixed on a durable physical medium
   277      customarily used for software interchange.
   278  
   279      b) Convey the object code in, or embodied in, a physical product
   280      (including a physical distribution medium), accompanied by a
   281      written offer, valid for at least three years and valid for as
   282      long as you offer spare parts or customer support for that product
   283      model, to give anyone who possesses the object code either (1) a
   284      copy of the Corresponding Source for all the software in the
   285      product that is covered by this License, on a durable physical
   286      medium customarily used for software interchange, for a price no
   287      more than your reasonable cost of physically performing this
   288      conveying of source, or (2) access to copy the
   289      Corresponding Source from a network server at no charge.
   290  
   291      c) Convey individual copies of the object code with a copy of the
   292      written offer to provide the Corresponding Source.  This
   293      alternative is allowed only occasionally and noncommercially, and
   294      only if you received the object code with such an offer, in accord
   295      with subsection 6b.
   296  
   297      d) Convey the object code by offering access from a designated
   298      place (gratis or for a charge), and offer equivalent access to the
   299      Corresponding Source in the same way through the same place at no
   300      further charge.  You need not require recipients to copy the
   301      Corresponding Source along with the object code.  If the place to
   302      copy the object code is a network server, the Corresponding Source
   303      may be on a different server (operated by you or a third party)
   304      that supports equivalent copying facilities, provided you maintain
   305      clear directions next to the object code saying where to find the
   306      Corresponding Source.  Regardless of what server hosts the
   307      Corresponding Source, you remain obligated to ensure that it is
   308      available for as long as needed to satisfy these requirements.
   309  
   310      e) Convey the object code using peer-to-peer transmission, provided
   311      you inform other peers where the object code and Corresponding
   312      Source of the work are being offered to the general public at no
   313      charge under subsection 6d.
   314  
   315    A separable portion of the object code, whose source code is excluded
   316  from the Corresponding Source as a System Library, need not be
   317  included in conveying the object code work.
   318  
   319    A "User Product" is either (1) a "consumer product", which means any
   320  tangible personal property which is normally used for personal, family,
   321  or household purposes, or (2) anything designed or sold for incorporation
   322  into a dwelling.  In determining whether a product is a consumer product,
   323  doubtful cases shall be resolved in favor of coverage.  For a particular
   324  product received by a particular user, "normally used" refers to a
   325  typical or common use of that class of product, regardless of the status
   326  of the particular user or of the way in which the particular user
   327  actually uses, or expects or is expected to use, the product.  A product
   328  is a consumer product regardless of whether the product has substantial
   329  commercial, industrial or non-consumer uses, unless such uses represent
   330  the only significant mode of use of the product.
   331  
   332    "Installation Information" for a User Product means any methods,
   333  procedures, authorization keys, or other information required to install
   334  and execute modified versions of a covered work in that User Product from
   335  a modified version of its Corresponding Source.  The information must
   336  suffice to ensure that the continued functioning of the modified object
   337  code is in no case prevented or interfered with solely because
   338  modification has been made.
   339  
   340    If you convey an object code work under this section in, or with, or
   341  specifically for use in, a User Product, and the conveying occurs as
   342  part of a transaction in which the right of possession and use of the
   343  User Product is transferred to the recipient in perpetuity or for a
   344  fixed term (regardless of how the transaction is characterized), the
   345  Corresponding Source conveyed under this section must be accompanied
   346  by the Installation Information.  But this requirement does not apply
   347  if neither you nor any third party retains the ability to install
   348  modified object code on the User Product (for example, the work has
   349  been installed in ROM).
   350  
   351    The requirement to provide Installation Information does not include a
   352  requirement to continue to provide support service, warranty, or updates
   353  for a work that has been modified or installed by the recipient, or for
   354  the User Product in which it has been modified or installed.  Access to a
   355  network may be denied when the modification itself materially and
   356  adversely affects the operation of the network or violates the rules and
   357  protocols for communication across the network.
   358  
   359    Corresponding Source conveyed, and Installation Information provided,
   360  in accord with this section must be in a format that is publicly
   361  documented (and with an implementation available to the public in
   362  source code form), and must require no special password or key for
   363  unpacking, reading or copying.
   364  
   365    7. Additional Terms.
   366  
   367    "Additional permissions" are terms that supplement the terms of this
   368  License by making exceptions from one or more of its conditions.
   369  Additional permissions that are applicable to the entire Program shall
   370  be treated as though they were included in this License, to the extent
   371  that they are valid under applicable law.  If additional permissions
   372  apply only to part of the Program, that part may be used separately
   373  under those permissions, but the entire Program remains governed by
   374  this License without regard to the additional permissions.
   375  
   376    When you convey a copy of a covered work, you may at your option
   377  remove any additional permissions from that copy, or from any part of
   378  it.  (Additional permissions may be written to require their own
   379  removal in certain cases when you modify the work.)  You may place
   380  additional permissions on material, added by you to a covered work,
   381  for which you have or can give appropriate copyright permission.
   382  
   383    Notwithstanding any other provision of this License, for material you
   384  add to a covered work, you may (if authorized by the copyright holders of
   385  that material) supplement the terms of this License with terms:
   386  
   387      a) Disclaiming warranty or limiting liability differently from the
   388      terms of sections 15 and 16 of this License; or
   389  
   390      b) Requiring preservation of specified reasonable legal notices or
   391      author attributions in that material or in the Appropriate Legal
   392      Notices displayed by works containing it; or
   393  
   394      c) Prohibiting misrepresentation of the origin of that material, or
   395      requiring that modified versions of such material be marked in
   396      reasonable ways as different from the original version; or
   397  
   398      d) Limiting the use for publicity purposes of names of licensors or
   399      authors of the material; or
   400  
   401      e) Declining to grant rights under trademark law for use of some
   402      trade names, trademarks, or service marks; or
   403  
   404      f) Requiring indemnification of licensors and authors of that
   405      material by anyone who conveys the material (or modified versions of
   406      it) with contractual assumptions of liability to the recipient, for
   407      any liability that these contractual assumptions directly impose on
   408      those licensors and authors.
   409  
   410    All other non-permissive additional terms are considered "further
   411  restrictions" within the meaning of section 10.  If the Program as you
   412  received it, or any part of it, contains a notice stating that it is
   413  governed by this License along with a term that is a further
   414  restriction, you may remove that term.  If a license document contains
   415  a further restriction but permits relicensing or conveying under this
   416  License, you may add to a covered work material governed by the terms
   417  of that license document, provided that the further restriction does
   418  not survive such relicensing or conveying.
   419  
   420    If you add terms to a covered work in accord with this section, you
   421  must place, in the relevant source files, a statement of the
   422  additional terms that apply to those files, or a notice indicating
   423  where to find the applicable terms.
   424  
   425    Additional terms, permissive or non-permissive, may be stated in the
   426  form of a separately written license, or stated as exceptions;
   427  the above requirements apply either way.
   428  
   429    8. Termination.
   430  
   431    You may not propagate or modify a covered work except as expressly
   432  provided under this License.  Any attempt otherwise to propagate or
   433  modify it is void, and will automatically terminate your rights under
   434  this License (including any patent licenses granted under the third
   435  paragraph of section 11).
   436  
   437    However, if you cease all violation of this License, then your
   438  license from a particular copyright holder is reinstated (a)
   439  provisionally, unless and until the copyright holder explicitly and
   440  finally terminates your license, and (b) permanently, if the copyright
   441  holder fails to notify you of the violation by some reasonable means
   442  prior to 60 days after the cessation.
   443  
   444    Moreover, your license from a particular copyright holder is
   445  reinstated permanently if the copyright holder notifies you of the
   446  violation by some reasonable means, this is the first time you have
   447  received notice of violation of this License (for any work) from that
   448  copyright holder, and you cure the violation prior to 30 days after
   449  your receipt of the notice.
   450  
   451    Termination of your rights under this section does not terminate the
   452  licenses of parties who have received copies or rights from you under
   453  this License.  If your rights have been terminated and not permanently
   454  reinstated, you do not qualify to receive new licenses for the same
   455  material under section 10.
   456  
   457    9. Acceptance Not Required for Having Copies.
   458  
   459    You are not required to accept this License in order to receive or
   460  run a copy of the Program.  Ancillary propagation of a covered work
   461  occurring solely as a consequence of using peer-to-peer transmission
   462  to receive a copy likewise does not require acceptance.  However,
   463  nothing other than this License grants you permission to propagate or
   464  modify any covered work.  These actions infringe copyright if you do
   465  not accept this License.  Therefore, by modifying or propagating a
   466  covered work, you indicate your acceptance of this License to do so.
   467  
   468    10. Automatic Licensing of Downstream Recipients.
   469  
   470    Each time you convey a covered work, the recipient automatically
   471  receives a license from the original licensors, to run, modify and
   472  propagate that work, subject to this License.  You are not responsible
   473  for enforcing compliance by third parties with this License.
   474  
   475    An "entity transaction" is a transaction transferring control of an
   476  organization, or substantially all assets of one, or subdividing an
   477  organization, or merging organizations.  If propagation of a covered
   478  work results from an entity transaction, each party to that
   479  transaction who receives a copy of the work also receives whatever
   480  licenses to the work the party's predecessor in interest had or could
   481  give under the previous paragraph, plus a right to possession of the
   482  Corresponding Source of the work from the predecessor in interest, if
   483  the predecessor has it or can get it with reasonable efforts.
   484  
   485    You may not impose any further restrictions on the exercise of the
   486  rights granted or affirmed under this License.  For example, you may
   487  not impose a license fee, royalty, or other charge for exercise of
   488  rights granted under this License, and you may not initiate litigation
   489  (including a cross-claim or counterclaim in a lawsuit) alleging that
   490  any patent claim is infringed by making, using, selling, offering for
   491  sale, or importing the Program or any portion of it.
   492  
   493    11. Patents.
   494  
   495    A "contributor" is a copyright holder who authorizes use under this
   496  License of the Program or a work on which the Program is based.  The
   497  work thus licensed is called the contributor's "contributor version".
   498  
   499    A contributor's "essential patent claims" are all patent claims
   500  owned or controlled by the contributor, whether already acquired or
   501  hereafter acquired, that would be infringed by some manner, permitted
   502  by this License, of making, using, or selling its contributor version,
   503  but do not include claims that would be infringed only as a
   504  consequence of further modification of the contributor version.  For
   505  purposes of this definition, "control" includes the right to grant
   506  patent sublicenses in a manner consistent with the requirements of
   507  this License.
   508  
   509    Each contributor grants you a non-exclusive, worldwide, royalty-free
   510  patent license under the contributor's essential patent claims, to
   511  make, use, sell, offer for sale, import and otherwise run, modify and
   512  propagate the contents of its contributor version.
   513  
   514    In the following three paragraphs, a "patent license" is any express
   515  agreement or commitment, however denominated, not to enforce a patent
   516  (such as an express permission to practice a patent or covenant not to
   517  sue for patent infringement).  To "grant" such a patent license to a
   518  party means to make such an agreement or commitment not to enforce a
   519  patent against the party.
   520  
   521    If you convey a covered work, knowingly relying on a patent license,
   522  and the Corresponding Source of the work is not available for anyone
   523  to copy, free of charge and under the terms of this License, through a
   524  publicly available network server or other readily accessible means,
   525  then you must either (1) cause the Corresponding Source to be so
   526  available, or (2) arrange to deprive yourself of the benefit of the
   527  patent license for this particular work, or (3) arrange, in a manner
   528  consistent with the requirements of this License, to extend the patent
   529  license to downstream recipients.  "Knowingly relying" means you have
   530  actual knowledge that, but for the patent license, your conveying the
   531  covered work in a country, or your recipient's use of the covered work
   532  in a country, would infringe one or more identifiable patents in that
   533  country that you have reason to believe are valid.
   534  
   535    If, pursuant to or in connection with a single transaction or
   536  arrangement, you convey, or propagate by procuring conveyance of, a
   537  covered work, and grant a patent license to some of the parties
   538  receiving the covered work authorizing them to use, propagate, modify
   539  or convey a specific copy of the covered work, then the patent license
   540  you grant is automatically extended to all recipients of the covered
   541  work and works based on it.
   542  
   543    A patent license is "discriminatory" if it does not include within
   544  the scope of its coverage, prohibits the exercise of, or is
   545  conditioned on the non-exercise of one or more of the rights that are
   546  specifically granted under this License.  You may not convey a covered
   547  work if you are a party to an arrangement with a third party that is
   548  in the business of distributing software, under which you make payment
   549  to the third party based on the extent of your activity of conveying
   550  the work, and under which the third party grants, to any of the
   551  parties who would receive the covered work from you, a discriminatory
   552  patent license (a) in connection with copies of the covered work
   553  conveyed by you (or copies made from those copies), or (b) primarily
   554  for and in connection with specific products or compilations that
   555  contain the covered work, unless you entered into that arrangement,
   556  or that patent license was granted, prior to 28 March 2007.
   557  
   558    Nothing in this License shall be construed as excluding or limiting
   559  any implied license or other defenses to infringement that may
   560  otherwise be available to you under applicable patent law.
   561  
   562    12. No Surrender of Others' Freedom.
   563  
   564    If conditions are imposed on you (whether by court order, agreement or
   565  otherwise) that contradict the conditions of this License, they do not
   566  excuse you from the conditions of this License.  If you cannot convey a
   567  covered work so as to satisfy simultaneously your obligations under this
   568  License and any other pertinent obligations, then as a consequence you may
   569  not convey it at all.  For example, if you agree to terms that obligate you
   570  to collect a royalty for further conveying from those to whom you convey
   571  the Program, the only way you could satisfy both those terms and this
   572  License would be to refrain entirely from conveying the Program.
   573  
   574    13. Remote Network Interaction; Use with the GNU General Public License.
   575  
   576    Notwithstanding any other provision of this License, if you modify the
   577  Program, your modified version must prominently offer all users
   578  interacting with it remotely through a computer network (if your version
   579  supports such interaction) an opportunity to receive the Corresponding
   580  Source of your version by providing access to the Corresponding Source
   581  from a network server at no charge, through some standard or customary
   582  means of facilitating copying of software.  This Corresponding Source
   583  shall include the Corresponding Source for any work covered by version 3
   584  of the GNU General Public License that is incorporated pursuant to the
   585  following paragraph.
   586  
   587    Notwithstanding any other provision of this License, you have
   588  permission to link or combine any covered work with a work licensed
   589  under version 3 of the GNU General Public License into a single
   590  combined work, and to convey the resulting work.  The terms of this
   591  License will continue to apply to the part which is the covered work,
   592  but the work with which it is combined will remain governed by version
   593  3 of the GNU General Public License.
   594  
   595    14. Revised Versions of this License.
   596  
   597    The Free Software Foundation may publish revised and/or new versions of
   598  the GNU Affero General Public License from time to time.  Such new versions
   599  will be similar in spirit to the present version, but may differ in detail to
   600  address new problems or concerns.
   601  
   602    Each version is given a distinguishing version number.  If the
   603  Program specifies that a certain numbered version of the GNU Affero General
   604  Public License "or any later version" applies to it, you have the
   605  option of following the terms and conditions either of that numbered
   606  version or of any later version published by the Free Software
   607  Foundation.  If the Program does not specify a version number of the
   608  GNU Affero General Public License, you may choose any version ever published
   609  by the Free Software Foundation.
   610  
   611    If the Program specifies that a proxy can decide which future
   612  versions of the GNU Affero General Public License can be used, that proxy's
   613  public statement of acceptance of a version permanently authorizes you
   614  to choose that version for the Program.
   615  
   616    Later license versions may give you additional or different
   617  permissions.  However, no additional obligations are imposed on any
   618  author or copyright holder as a result of your choosing to follow a
   619  later version.
   620  
   621    15. Disclaimer of Warranty.
   622  
   623    THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
   624  APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
   625  HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
   626  OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
   627  THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
   628  PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
   629  IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
   630  ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
   631  
   632    16. Limitation of Liability.
   633  
   634    IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
   635  WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
   636  THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
   637  GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
   638  USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
   639  DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
   640  PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
   641  EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
   642  SUCH DAMAGES.
   643  
   644    17. Interpretation of Sections 15 and 16.
   645  
   646    If the disclaimer of warranty and limitation of liability provided
   647  above cannot be given local legal effect according to their terms,
   648  reviewing courts shall apply local law that most closely approximates
   649  an absolute waiver of all civil liability in connection with the
   650  Program, unless a warranty or assumption of liability accompanies a
   651  copy of the Program in return for a fee.
   652  
   653                       END OF TERMS AND CONDITIONS
   654  
   655              How to Apply These Terms to Your New Programs
   656  
   657    If you develop a new program, and you want it to be of the greatest
   658  possible use to the public, the best way to achieve this is to make it
   659  free software which everyone can redistribute and change under these terms.
   660  
   661    To do so, attach the following notices to the program.  It is safest
   662  to attach them to the start of each source file to most effectively
   663  state the exclusion of warranty; and each file should have at least
   664  the "copyright" line and a pointer to where the full notice is found.
   665  
   666      <one line to give the program's name and a brief idea of what it does.>
   667      Copyright (C) <year>  <name of author>
   668  
   669      This program is free software: you can redistribute it and/or modify
   670      it under the terms of the GNU Affero General Public License as published by
   671      the Free Software Foundation, either version 3 of the License, or
   672      (at your option) any later version.
   673  
   674      This program is distributed in the hope that it will be useful,
   675      but WITHOUT ANY WARRANTY; without even the implied warranty of
   676      MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
   677      GNU Affero General Public License for more details.
   678  
   679      You should have received a copy of the GNU Affero General Public License
   680      along with this program.  If not, see <http://www.gnu.org/licenses/>.
   681  
   682  Also add information on how to contact you by electronic and paper mail.
   683  
   684    If your software can interact with users remotely through a computer
   685  network, you should also make sure that it provides a way for users to
   686  get its source.  For example, if your program is a web application, its
   687  interface could display a "Source" link that leads users to an archive
   688  of the code.  There are many ways you could offer source, and different
   689  solutions will be better for different programs; see section 13 for the
   690  specific requirements.
   691  
   692    You should also get your employer (if you work as a programmer) or school,
   693  if any, to sign a "copyright disclaimer" for the program, if necessary.
