\begin{abstract}
franta-hg@12
    23
The GNU Affero General Public License is a free, copyleft license
franta-hg@12
    24
for software and other kinds of works, specifically designed to ensure
franta-hg@12
    25
cooperation with the community in the case of network server software.
franta-hg@12
    26
franta-hg@12
    27
The licenses for most software and other practical works are
franta-hg@12
    28
designed to take away your freedom to share and change the works.  By
franta-hg@12
    29
contrast, our General Public Licenses are intended to guarantee your
franta-hg@12
    30
freedom to share and change all versions of a program--to make sure it
franta-hg@12
    31
remains free software for all its users.
franta-hg@12
    32
franta-hg@12
    33
When we speak of free software, we are referring to freedom, not
franta-hg@12
    34
price.  Our General Public Licenses are designed to make sure that you
franta-hg@12
    35
have the freedom to distribute copies of free software (and charge for
franta-hg@12
    36
them if you wish), that you receive source code or can get it if you
franta-hg@12
    37
want it, that you can change the software or use pieces of it in new
franta-hg@12
    38
free programs, and that you know you can do these things.
franta-hg@12
    39
franta-hg@12
    40
Developers that use our General Public Licenses protect your rights
franta-hg@12
    41
with two steps: (1) assert copyright on the software, and (2) offer
franta-hg@12
    42
you this License which gives you legal permission to copy, distribute
franta-hg@12
    43
and/or modify the software.
franta-hg@12
    44
franta-hg@12
    45
A secondary benefit of defending all users' freedom is that
franta-hg@12
    46
improvements made in alternate versions of the program, if they
franta-hg@12
    47
receive widespread use, become available for other developers to
franta-hg@12
    48
incorporate.  Many developers of free software are heartened and
franta-hg@12
    49
encouraged by the resulting cooperation.  However, in the case of
franta-hg@12
    50
software used on network servers, this result may fail to come about.
franta-hg@12
    51
The GNU General Public License permits making a modified version and
franta-hg@12
    52
letting the public access it on a server without ever releasing its
franta-hg@12
    53
source code to the public.
franta-hg@12
    54
franta-hg@12
    55
The GNU Affero General Public License is designed specifically to
franta-hg@12
    56
ensure that, in such cases, the modified source code becomes available
franta-hg@12
    57
to the community.  It requires the operator of a network server to
franta-hg@12
    58
provide the source code of the modified version running there to the
franta-hg@12
    59
users of that server.  Therefore, public use of a modified version, on
franta-hg@12
    60
a publicly accessible server, gives the public access to the source
franta-hg@12
    61
code of the modified version.
franta-hg@12
    62
franta-hg@12
    63
An older license, called the Affero General Public License and
franta-hg@12
    64
published by Affero, was designed to accomplish similar goals.  This is
franta-hg@12
    65
a different license, not a version of the Affero GPL, but Affero has
franta-hg@12
    66
released a new version of the Affero GPL which permits relicensing under
franta-hg@12
    67
this license.
franta-hg@12
    68
franta-hg@12
    69
The precise terms and conditions for copying, distribution and
franta-hg@12
    70
modification follow.

\item Definitions.
franta-hg@12
    83
franta-hg@12
    84
``This License'' refers to version 3 of the GNU Affero General Public License.
franta-hg@12
    85
franta-hg@12
    86
``Copyright'' also means copyright-like laws that apply to other kinds of
franta-hg@12
    87
works, such as semiconductor masks.
franta-hg@12
    88
franta-hg@12
    89
``The Program'' refers to any copyrightable work licensed under this
franta-hg@12
    90
License.  Each licensee is addressed as ``you''.  ``Licensees'' and
franta-hg@12
    91
``recipients'' may be individuals or organizations.
franta-hg@12
    92
franta-hg@12
    93
To ``modify'' a work means to copy from or adapt all or part of the work
franta-hg@12
    94
in a fashion requiring copyright permission, other than the making of an
franta-hg@12
    95
exact copy.  The resulting work is called a ``modified version'' of the
franta-hg@12
    96
earlier work or a work ``based on'' the earlier work.
franta-hg@12
    97
franta-hg@12
    98
A ``covered work'' means either the unmodified Program or a work based
franta-hg@12
    99
on the Program.
franta-hg@12
   100
franta-hg@12
   101
To ``propagate'' a work means to do anything with it that, without
franta-hg@12
   102
permission, would make you directly or secondarily liable for
franta-hg@12
   103
infringement under applicable copyright law, except executing it on a
franta-hg@12
   104
computer or modifying a private copy.  Propagation includes copying,
franta-hg@12
   105
distribution (with or without modification), making available to the
franta-hg@12
   106
public, and in some countries other activities as well.
franta-hg@12
   107
franta-hg@12
   108
To ``convey'' a work means any kind of propagation that enables other
franta-hg@12
   109
parties to make or receive copies.  Mere interaction with a user through
franta-hg@12
   110
a computer network, with no transfer of a copy, is not conveying.
franta-hg@12
   111
franta-hg@12
   112
An interactive user interface displays ``Appropriate Legal Notices''
franta-hg@12
   113
to the extent that it includes a convenient and prominently visible
franta-hg@12
   114
feature that (1) displays an appropriate copyright notice, and (2)
franta-hg@12
   115
tells the user that there is no warranty for the work (except to the
franta-hg@12
   116
extent that warranties are provided), that licensees may convey the
franta-hg@12
   117
work under this License, and how to view a copy of this License.  If
franta-hg@12
   118
the interface presents a list of user commands or options, such as a
franta-hg@12
   119
menu, a prominent item in the list meets this criterion.
franta-hg@12
   120
franta-hg@12
   121
\item Source Code.
franta-hg@12
   122
franta-hg@12
   123
The ``source code'' for a work means the preferred form of the work
franta-hg@12
   124
for making modifications to it.  ``Object code'' means any non-source
franta-hg@12
   125
form of a work.
franta-hg@12
   126
franta-hg@12
   127
A ``Standard Interface'' means an interface that either is an official
franta-hg@12
   128
standard defined by a recognized standards body, or, in the case of
franta-hg@12
   129
interfaces specified for a particular programming language, one that
franta-hg@12
   130
is widely used among developers working in that language.
franta-hg@12
   131
franta-hg@12
   132
The ``System Libraries'' of an executable work include anything, other
franta-hg@12
   133
than the work as a whole, that (a) is included in the normal form of
franta-hg@12
   134
packaging a Major Component, but which is not part of that Major
franta-hg@12
   135
Component, and (b) serves only to enable use of the work with that
franta-hg@12
   136
Major Component, or to implement a Standard Interface for which an
franta-hg@12
   137
implementation is available to the public in source code form.  A
franta-hg@12
   138
``Major Component'', in this context, means a major essential component
franta-hg@12
   139
(kernel, window system, and so on) of the specific operating system
franta-hg@12
   140
(if any) on which the executable work runs, or a compiler used to
franta-hg@12
   141
produce the work, or an object code interpreter used to run it.
franta-hg@12
   142
franta-hg@12
   143
The ``Corresponding Source'' for a work in object code form means all
franta-hg@12
   144
the source code needed to generate, install, and (for an executable
franta-hg@12
   145
work) run the object code and to modify the work, including scripts to
franta-hg@12
   146
control those activities.  However, it does not include the work's
franta-hg@12
   147
System Libraries, or general-purpose tools or generally available free
franta-hg@12
   148
programs which are used unmodified in performing those activities but
franta-hg@12
   149
which are not part of the work.  For example, Corresponding Source
franta-hg@12
   150
includes interface definition files associated with source files for
franta-hg@12
   151
the work, and the source code for shared libraries and dynamically
franta-hg@12
   152
linked subprograms that the work is specifically designed to require,
franta-hg@12
   153
such as by intimate data communication or control flow between those
franta-hg@12
   154
subprograms and other parts of the work.
franta-hg@12
   155
franta-hg@12
   156
The Corresponding Source need not include anything that users
franta-hg@12
   157
can regenerate automatically from other parts of the Corresponding
franta-hg@12
   158
Source.
franta-hg@12
   159
franta-hg@12
   160
The Corresponding Source for a work in source code form is that
franta-hg@12
   161
same work.
franta-hg@12
   162
franta-hg@12
   163
\item Basic Permissions.
franta-hg@12
   164
franta-hg@12
   165
All rights granted under this License are granted for the term of
franta-hg@12
   166
copyright on the Program, and are irrevocable provided the stated
franta-hg@12
   167
conditions are met.  This License explicitly affirms your unlimited
franta-hg@12
   168
permission to run the unmodified Program.  The output from running a
franta-hg@12
   169
covered work is covered by this License only if the output, given its
franta-hg@12
   170
content, constitutes a covered work.  This License acknowledges your
franta-hg@12
   171
rights of fair use or other equivalent, as provided by copyright law.
franta-hg@12
   172
franta-hg@12
   173
You may make, run and propagate covered works that you do not
franta-hg@12
   174
convey, without conditions so long as your license otherwise remains
franta-hg@12
   175
in force.  You may convey covered works to others for the sole purpose
franta-hg@12
   176
of having them make modifications exclusively for you, or provide you
franta-hg@12
   177
with facilities for running those works, provided that you comply with
franta-hg@12
   178
the terms of this License in conveying all material for which you do
franta-hg@12
   179
not control copyright.  Those thus making or running the covered works
franta-hg@12
   180
for you must do so exclusively on your behalf, under your direction
franta-hg@12
   181
and control, on terms that prohibit them from making any copies of
franta-hg@12
   182
your copyrighted material outside their relationship with you.
franta-hg@12
   183
franta-hg@12
   184
Conveying under any other circumstances is permitted solely under
franta-hg@12
   185
the conditions stated below.  Sublicensing is not allowed; section 10
franta-hg@12
   186
makes it unnecessary.
franta-hg@12
   187
franta-hg@12
   188
\item Protecting Users' Legal Rights From Anti-Circumvention Law.
franta-hg@12
   189
franta-hg@12
   190
No covered work shall be deemed part of an effective technological
franta-hg@12
   191
measure under any applicable law fulfilling obligations under article
franta-hg@12
   192
11 of the WIPO copyright treaty adopted on 20 December 1996, or
franta-hg@12
   193
similar laws prohibiting or restricting circumvention of such
franta-hg@12
   194
measures.
franta-hg@12
   195
franta-hg@12
   196
When you convey a covered work, you waive any legal power to forbid
franta-hg@12
   197
circumvention of technological measures to the extent such circumvention
franta-hg@12
   198
is effected by exercising rights under this License with respect to
franta-hg@12
   199
the covered work, and you disclaim any intention to limit operation or
franta-hg@12
   200
modification of the work as a means of enforcing, against the work's
franta-hg@12
   201
users, your or third parties' legal rights to forbid circumvention of
franta-hg@12
   202
technological measures.
franta-hg@12
   203
franta-hg@12
   204
\item Conveying Verbatim Copies.
franta-hg@12
   205
franta-hg@12
   206
You may convey verbatim copies of the Program's source code as you
franta-hg@12
   207
receive it, in any medium, provided that you conspicuously and
franta-hg@12
   208
appropriately publish on each copy an appropriate copyright notice;
franta-hg@12
   209
keep intact all notices stating that this License and any
franta-hg@12
   210
non-permissive terms added in accord with section 7 apply to the code;
franta-hg@12
   211
keep intact all notices of the absence of any warranty; and give all
franta-hg@12
   212
recipients a copy of this License along with the Program.
franta-hg@12
   213
franta-hg@12
   214
You may charge any price or no price for each copy that you convey,
franta-hg@12
   215
and you may offer support or warranty protection for a fee.
franta-hg@12
   216
franta-hg@12
   217
\item Conveying Modified Source Versions.
franta-hg@12
   218
franta-hg@12
   219
You may convey a work based on the Program, or the modifications to
franta-hg@12
   220
produce it from the Program, in the form of source code under the
franta-hg@12
   221
terms of section 4, provided that you also meet all of these conditions:
franta-hg@12
   222
  \begin{enumerate}
franta-hg@12
   223
  \item The work must carry prominent notices stating that you modified
franta-hg@12
   224
  it, and giving a relevant date.
franta-hg@12
   225
franta-hg@12
   226
  \item The work must carry prominent notices stating that it is
franta-hg@12
   227
  released under this License and any conditions added under section
franta-hg@12
   228
  7.  This requirement modifies the requirement in section 4 to
franta-hg@12
   229
  ``keep intact all notices''.
franta-hg@12
   230
franta-hg@12
   231
  \item You must license the entire work, as a whole, under this
franta-hg@12
   232
  License to anyone who comes into possession of a copy.  This
franta-hg@12
   233
  License will therefore apply, along with any applicable section 7
franta-hg@12
   234
  additional terms, to the whole of the work, and all its parts,
franta-hg@12
   235
  regardless of how they are packaged.  This License gives no
franta-hg@12
   236
  permission to license the work in any other way, but it does not
franta-hg@12
   237
  invalidate such permission if you have separately received it.
franta-hg@12
   238
franta-hg@12
   239
  \item If the work has interactive user interfaces, each must display
franta-hg@12
   240
  Appropriate Legal Notices; however, if the Program has interactive
franta-hg@12
   241
  interfaces that do not display Appropriate Legal Notices, your
franta-hg@12
   242
  work need not make them do so.
franta-hg@12
   243
\end{enumerate}
franta-hg@12
   244
A compilation of a covered work with other separate and independent
franta-hg@12
   245
works, which are not by their nature extensions of the covered work,
franta-hg@12
   246
and which are not combined with it such as to form a larger program,
franta-hg@12
   247
in or on a volume of a storage or distribution medium, is called an
franta-hg@12
   248
``aggregate'' if the compilation and its resulting copyright are not
franta-hg@12
   249
used to limit the access or legal rights of the compilation's users
franta-hg@12
   250
beyond what the individual works permit.  Inclusion of a covered work
franta-hg@12
   251
in an aggregate does not cause this License to apply to the other
franta-hg@12
   252
parts of the aggregate.
franta-hg@12
   253
franta-hg@12
   254
\item Conveying Non-Source Forms.
franta-hg@12
   255
franta-hg@12
   256
You may convey a covered work in object code form under the terms
franta-hg@12
   257
of sections 4 and 5, provided that you also convey the
franta-hg@12
   258
machine-readable Corresponding Source under the terms of this License,
franta-hg@12
   259
in one of these ways:
franta-hg@12
   260
  \begin{enumerate}
franta-hg@12
   261
  \item Convey the object code in, or embodied in, a physical product
franta-hg@12
   262
  (including a physical distribution medium), accompanied by the
franta-hg@12
   263
  Corresponding Source fixed on a durable physical medium
franta-hg@12
   264
  customarily used for software interchange.
franta-hg@12
   265
franta-hg@12
   266
  \item Convey the object code in, or embodied in, a physical product
franta-hg@12
   267
  (including a physical distribution medium), accompanied by a
franta-hg@12
   268
  written offer, valid for at least three years and valid for as
franta-hg@12
   269
  long as you offer spare parts or customer support for that product
franta-hg@12
   270
  model, to give anyone who possesses the object code either (1) a
franta-hg@12
   271
  copy of the Corresponding Source for all the software in the
franta-hg@12
   272
  product that is covered by this License, on a durable physical
franta-hg@12
   273
  medium customarily used for software interchange, for a price no
franta-hg@12
   274
  more than your reasonable cost of physically performing this
franta-hg@12
   275
  conveying of source, or (2) access to copy the
franta-hg@12
   276
  Corresponding Source from a network server at no charge.
franta-hg@12
   277
franta-hg@12
   278
  \item Convey individual copies of the object code with a copy of the
franta-hg@12
   279
  written offer to provide the Corresponding Source.  This
franta-hg@12
   280
  alternative is allowed only occasionally and noncommercially, and
franta-hg@12
   281
  only if you received the object code with such an offer, in accord
franta-hg@12
   282
  with subsection 6b.
franta-hg@12
   283
franta-hg@12
   284
  \item Convey the object code by offering access from a designated
franta-hg@12
   285
  place (gratis or for a charge), and offer equivalent access to the
franta-hg@12
   286
  Corresponding Source in the same way through the same place at no
franta-hg@12
   287
  further charge.  You need not require recipients to copy the
franta-hg@12
   288
  Corresponding Source along with the object code.  If the place to
franta-hg@12
   289
  copy the object code is a network server, the Corresponding Source
franta-hg@12
   290
  may be on a different server (operated by you or a third party)
franta-hg@12
   291
  that supports equivalent copying facilities, provided you maintain
franta-hg@12
   292
  clear directions next to the object code saying where to find the
franta-hg@12
   293
  Corresponding Source.  Regardless of what server hosts the
franta-hg@12
   294
  Corresponding Source, you remain obligated to ensure that it is
franta-hg@12
   295
  available for as long as needed to satisfy these requirements.
franta-hg@12
   296
franta-hg@12
   297
  \item Convey the object code using peer-to-peer transmission, provided
franta-hg@12
   298
  you inform other peers where the object code and Corresponding
franta-hg@12
   299
  Source of the work are being offered to the general public at no
franta-hg@12
   300
  charge under subsection 6d.
franta-hg@12
   301
  \end{enumerate}
franta-hg@12
   302
franta-hg@12
   303
A separable portion of the object code, whose source code is excluded
franta-hg@12
   304
from the Corresponding Source as a System Library, need not be
franta-hg@12
   305
included in conveying the object code work.
franta-hg@12
   306
franta-hg@12
   307
A ``User Product'' is either (1) a ``consumer product'', which means any
franta-hg@12
   308
tangible personal property which is normally used for personal, family,
franta-hg@12
   309
or household purposes, or (2) anything designed or sold for incorporation
franta-hg@12
   310
into a dwelling.  In determining whether a product is a consumer product,
franta-hg@12
   311
doubtful cases shall be resolved in favor of coverage.  For a particular
franta-hg@12
   312
product received by a particular user, ``normally used'' refers to a
franta-hg@12
   313
typical or common use of that class of product, regardless of the status
franta-hg@12
   314
of the particular user or of the way in which the particular user
franta-hg@12
   315
actually uses, or expects or is expected to use, the product.  A product
franta-hg@12
   316
is a consumer product regardless of whether the product has substantial
franta-hg@12
   317
commercial, industrial or non-consumer uses, unless such uses represent
franta-hg@12
   318
the only significant mode of use of the product.
franta-hg@12
   319
franta-hg@12
   320
``Installation Information'' for a User Product means any methods,
franta-hg@12
   321
procedures, authorization keys, or other information required to install
franta-hg@12
   322
and execute modified versions of a covered work in that User Product from
franta-hg@12
   323
a modified version of its Corresponding Source.  The information must
franta-hg@12
   324
suffice to ensure that the continued functioning of the modified object
franta-hg@12
   325
code is in no case prevented or interfered with solely because
franta-hg@12
   326
modification has been made.
franta-hg@12
   327
franta-hg@12
   328
If you convey an object code work under this section in, or with, or
franta-hg@12
   329
specifically for use in, a User Product, and the conveying occurs as
franta-hg@12
   330
part of a transaction in which the right of possession and use of the
franta-hg@12
   331
User Product is transferred to the recipient in perpetuity or for a
franta-hg@12
   332
fixed term (regardless of how the transaction is characterized), the
franta-hg@12
   333
Corresponding Source conveyed under this section must be accompanied
franta-hg@12
   334
by the Installation Information.  But this requirement does not apply
franta-hg@12
   335
if neither you nor any third party retains the ability to install
franta-hg@12
   336
modified object code on the User Product (for example, the work has
franta-hg@12
   337
been installed in ROM).
franta-hg@12
   338
franta-hg@12
   339
The requirement to provide Installation Information does not include a
franta-hg@12
   340
requirement to continue to provide support service, warranty, or updates
franta-hg@12
   341
for a work that has been modified or installed by the recipient, or for
franta-hg@12
   342
the User Product in which it has been modified or installed.  Access to a
franta-hg@12
   343
network may be denied when the modification itself materially and
franta-hg@12
   344
adversely affects the operation of the network or violates the rules and
franta-hg@12
   345
protocols for communication across the network.
franta-hg@12
   346
franta-hg@12
   347
Corresponding Source conveyed, and Installation Information provided,
franta-hg@12
   348
in accord with this section must be in a format that is publicly
franta-hg@12
   349
documented (and with an implementation available to the public in
franta-hg@12
   350
source code form), and must require no special password or key for
franta-hg@12
   351
unpacking, reading or copying.
franta-hg@12
   352
franta-hg@12
   353
\item Additional Terms.
franta-hg@12
   354
franta-hg@12
   355
``Additional permissions'' are terms that supplement the terms of this
franta-hg@12
   356
License by making exceptions from one or more of its conditions.
franta-hg@12
   357
Additional permissions that are applicable to the entire Program shall
franta-hg@12
   358
be treated as though they were included in this License, to the extent
franta-hg@12
   359
that they are valid under applicable law.  If additional permissions
franta-hg@12
   360
apply only to part of the Program, that part may be used separately
franta-hg@12
   361
under those permissions, but the entire Program remains governed by
franta-hg@12
   362
this License without regard to the additional permissions.
franta-hg@12
   363
franta-hg@12
   364
When you convey a copy of a covered work, you may at your option
franta-hg@12
   365
remove any additional permissions from that copy, or from any part of
franta-hg@12
   366
it.  (Additional permissions may be written to require their own
franta-hg@12
   367
removal in certain cases when you modify the work.)  You may place
franta-hg@12
   368
additional permissions on material, added by you to a covered work,
franta-hg@12
   369
for which you have or can give appropriate copyright permission.
franta-hg@12
   370
franta-hg@12
   371
Notwithstanding any other provision of this License, for material you
franta-hg@12
   372
add to a covered work, you may (if authorized by the copyright holders of
franta-hg@12
   373
that material) supplement the terms of this License with terms:
franta-hg@12
   374
  \begin{enumerate}
franta-hg@12
   375
  \item Disclaiming warranty or limiting liability differently from the
franta-hg@12
   376
  terms of sections 15 and 16 of this License; or
franta-hg@12
   377
franta-hg@12
   378
  \item Requiring preservation of specified reasonable legal notices or
franta-hg@12
   379
  author attributions in that material or in the Appropriate Legal
franta-hg@12
   380
  Notices displayed by works containing it; or
franta-hg@12
   381
franta-hg@12
   382
  \item Prohibiting misrepresentation of the origin of that material, or
franta-hg@12
   383
  requiring that modified versions of such material be marked in
franta-hg@12
   384
  reasonable ways as different from the original version; or
franta-hg@12
   385
franta-hg@12
   386
  \item Limiting the use for publicity purposes of names of licensors or
franta-hg@12
   387
  authors of the material; or
franta-hg@12
   388
franta-hg@12
   389
  \item Declining to grant rights under trademark law for use of some
franta-hg@12
   390
  trade names, trademarks, or service marks; or
franta-hg@12
   391
franta-hg@12
   392
  \item Requiring indemnification of licensors and authors of that
franta-hg@12
   393
  material by anyone who conveys the material (or modified versions of
franta-hg@12
   394
  it) with contractual assumptions of liability to the recipient, for
franta-hg@12
   395
  any liability that these contractual assumptions directly impose on
franta-hg@12
   396
  those licensors and authors.
franta-hg@12
   397
  \end{enumerate}
franta-hg@12
   398
franta-hg@12
   399
All other non-permissive additional terms are considered ``further
franta-hg@12
   400
restrictions'' within the meaning of section 10.  If the Program as you
franta-hg@12
   401
received it, or any part of it, contains a notice stating that it is
franta-hg@12
   402
governed by this License along with a term that is a further
franta-hg@12
   403
restriction, you may remove that term.  If a license document contains
franta-hg@12
   404
a further restriction but permits relicensing or conveying under this
franta-hg@12
   405
License, you may add to a covered work material governed by the terms
franta-hg@12
   406
of that license document, provided that the further restriction does
franta-hg@12
   407
not survive such relicensing or conveying.
franta-hg@12
   408
franta-hg@12
   409
If you add terms to a covered work in accord with this section, you
franta-hg@12
   410
must place, in the relevant source files, a statement of the
franta-hg@12
   411
additional terms that apply to those files, or a notice indicating
franta-hg@12
   412
where to find the applicable terms.
franta-hg@12
   413
franta-hg@12
   414
Additional terms, permissive or non-permissive, may be stated in the
franta-hg@12
   415
form of a separately written license, or stated as exceptions;
franta-hg@12
   416
the above requirements apply either way.
franta-hg@12
   417
franta-hg@12
   418
\item Termination.
franta-hg@12
   419
franta-hg@12
   420
You may not propagate or modify a covered work except as expressly
franta-hg@12
   421
provided under this License.  Any attempt otherwise to propagate or
franta-hg@12
   422
modify it is void, and will automatically terminate your rights under
franta-hg@12
   423
this License (including any patent licenses granted under the third
franta-hg@12
   424
paragraph of section 11).
franta-hg@12
   425
franta-hg@12
   426
However, if you cease all violation of this License, then your
franta-hg@12
   427
license from a particular copyright holder is reinstated (a)
franta-hg@12
   428
provisionally, unless and until the copyright holder explicitly and
franta-hg@12
   429
finally terminates your license, and (b) permanently, if the copyright
franta-hg@12
   430
holder fails to notify you of the violation by some reasonable means
franta-hg@12
   431
prior to 60 days after the cessation.
franta-hg@12
   432
franta-hg@12
   433
Moreover, your license from a particular copyright holder is
franta-hg@12
   434
reinstated permanently if the copyright holder notifies you of the
franta-hg@12
   435
violation by some reasonable means, this is the first time you have
franta-hg@12
   436
received notice of violation of this License (for any work) from that
franta-hg@12
   437
copyright holder, and you cure the violation prior to 30 days after
franta-hg@12
   438
your receipt of the notice.
franta-hg@12
   439
franta-hg@12
   440
Termination of your rights under this section does not terminate the
franta-hg@12
   441
licenses of parties who have received copies or rights from you under
franta-hg@12
   442
this License.  If your rights have been terminated and not permanently
franta-hg@12
   443
reinstated, you do not qualify to receive new licenses for the same
franta-hg@12
   444
material under section 10.
franta-hg@12
   445
franta-hg@12
   446
\item Acceptance Not Required for Having Copies.
franta-hg@12
   447
franta-hg@12
   448
You are not required to accept this License in order to receive or
franta-hg@12
   449
run a copy of the Program.  Ancillary propagation of a covered work
franta-hg@12
   450
occurring solely as a consequence of using peer-to-peer transmission
franta-hg@12
   451
to receive a copy likewise does not require acceptance.  However,
franta-hg@12
   452
nothing other than this License grants you permission to propagate or
franta-hg@12
   453
modify any covered work.  These actions infringe copyright if you do
franta-hg@12
   454
not accept this License.  Therefore, by modifying or propagating a
franta-hg@12
   455
covered work, you indicate your acceptance of this License to do so.
franta-hg@12
   456
franta-hg@12
   457
\item Automatic Licensing of Downstream Recipients.
franta-hg@12
   458
franta-hg@12
   459
Each time you convey a covered work, the recipient automatically
franta-hg@12
   460
receives a license from the original licensors, to run, modify and
franta-hg@12
   461
propagate that work, subject to this License.  You are not responsible
franta-hg@12
   462
for enforcing compliance by third parties with this License.
franta-hg@12
   463
franta-hg@12
   464
An ``entity transaction'' is a transaction transferring control of an
franta-hg@12
   465
organization, or substantially all assets of one, or subdividing an
franta-hg@12
   466
organization, or merging organizations.  If propagation of a covered
franta-hg@12
   467
work results from an entity transaction, each party to that
franta-hg@12
   468
transaction who receives a copy of the work also receives whatever
franta-hg@12
   469
licenses to the work the party's predecessor in interest had or could
franta-hg@12
   470
give under the previous paragraph, plus a right to possession of the
franta-hg@12
   471
Corresponding Source of the work from the predecessor in interest, if
franta-hg@12
   472
the predecessor has it or can get it with reasonable efforts.
franta-hg@12
   473
franta-hg@12
   474
You may not impose any further restrictions on the exercise of the
franta-hg@12
   475
rights granted or affirmed under this License.  For example, you may
franta-hg@12
   476
not impose a license fee, royalty, or other charge for exercise of
franta-hg@12
   477
rights granted under this License, and you may not initiate litigation
franta-hg@12
   478
(including a cross-claim or counterclaim in a lawsuit) alleging that
franta-hg@12
   479
any patent claim is infringed by making, using, selling, offering for
franta-hg@12
   480
sale, or importing the Program or any portion of it.
franta-hg@12
   481
franta-hg@12
   482
\item Patents.
franta-hg@12
   483
franta-hg@12
   484
A ``contributor'' is a copyright holder who authorizes use under this
franta-hg@12
   485
License of the Program or a work on which the Program is based.  The
franta-hg@12
   486
work thus licensed is called the contributor's ``contributor version''.
franta-hg@12
   487
franta-hg@12
   488
A contributor's ``essential patent claims'' are all patent claims
franta-hg@12
   489
owned or controlled by the contributor, whether already acquired or
franta-hg@12
   490
hereafter acquired, that would be infringed by some manner, permitted
franta-hg@12
   491
by this License, of making, using, or selling its contributor version,
franta-hg@12
   492
but do not include claims that would be infringed only as a
franta-hg@12
   493
consequence of further modification of the contributor version.  For
franta-hg@12
   494
purposes of this definition, ``control'' includes the right to grant
franta-hg@12
   495
patent sublicenses in a manner consistent with the requirements of
franta-hg@12
   496
this License.
franta-hg@12
   497
franta-hg@12
   498
Each contributor grants you a non-exclusive, worldwide, royalty-free
franta-hg@12
   499
patent license under the contributor's essential patent claims, to
franta-hg@12
   500
make, use, sell, offer for sale, import and otherwise run, modify and
franta-hg@12
   501
propagate the contents of its contributor version.
franta-hg@12
   502
franta-hg@12
   503
In the following three paragraphs, a ``patent license'' is any express
franta-hg@12
   504
agreement or commitment, however denominated, not to enforce a patent
franta-hg@12
   505
(such as an express permission to practice a patent or covenant not to
franta-hg@12
   506
sue for patent infringement).  To ``grant'' such a patent license to a
franta-hg@12
   507
party means to make such an agreement or commitment not to enforce a
franta-hg@12
   508
patent against the party.
franta-hg@12
   509
franta-hg@12
   510
If you convey a covered work, knowingly relying on a patent license,
franta-hg@12
   511
and the Corresponding Source of the work is not available for anyone
franta-hg@12
   512
to copy, free of charge and under the terms of this License, through a
franta-hg@12
   513
publicly available network server or other readily accessible means,
franta-hg@12
   514
then you must either (1) cause the Corresponding Source to be so
franta-hg@12
   515
available, or (2) arrange to deprive yourself of the benefit of the
franta-hg@12
   516
patent license for this particular work, or (3) arrange, in a manner
franta-hg@12
   517
consistent with the requirements of this License, to extend the patent
franta-hg@12
   518
license to downstream recipients.  ``Knowingly relying'' means you have
franta-hg@12
   519
actual knowledge that, but for the patent license, your conveying the
franta-hg@12
   520
covered work in a country, or your recipient's use of the covered work
franta-hg@12
   521
in a country, would infringe one or more identifiable patents in that
franta-hg@12
   522
country that you have reason to believe are valid.
franta-hg@12
   523
franta-hg@12
   524
If, pursuant to or in connection with a single transaction or
franta-hg@12
   525
arrangement, you convey, or propagate by procuring conveyance of, a
franta-hg@12
   526
covered work, and grant a patent license to some of the parties
franta-hg@12
   527
receiving the covered work authorizing them to use, propagate, modify
franta-hg@12
   528
or convey a specific copy of the covered work, then the patent license
franta-hg@12
   529
you grant is automatically extended to all recipients of the covered
franta-hg@12
   530
work and works based on it.
franta-hg@12
   531
franta-hg@12
   532
A patent license is ``discriminatory'' if it does not include within
franta-hg@12
   533
the scope of its coverage, prohibits the exercise of, or is
franta-hg@12
   534
conditioned on the non-exercise of one or more of the rights that are
franta-hg@12
   535
specifically granted under this License.  You may not convey a covered
franta-hg@12
   536
work if you are a party to an arrangement with a third party that is
franta-hg@12
   537
in the business of distributing software, under which you make payment
franta-hg@12
   538
to the third party based on the extent of your activity of conveying
franta-hg@12
   539
the work, and under which the third party grants, to any of the
franta-hg@12
   540
parties who would receive the covered work from you, a discriminatory
franta-hg@12
   541
patent license (a) in connection with copies of the covered work
franta-hg@12
   542
conveyed by you (or copies made from those copies), or (b) primarily
franta-hg@12
   543
for and in connection with specific products or compilations that
franta-hg@12
   544
contain the covered work, unless you entered into that arrangement,
franta-hg@12
   545
or that patent license was granted, prior to 28 March 2007.
franta-hg@12
   546
franta-hg@12
   547
Nothing in this License shall be construed as excluding or limiting
franta-hg@12
   548
any implied license or other defenses to infringement that may
franta-hg@12
   549
otherwise be available to you under applicable patent law.
franta-hg@12
   550
franta-hg@12
   551
\item No Surrender of Others' Freedom.
franta-hg@12
   552
franta-hg@12
   553
If conditions are imposed on you (whether by court order, agreement or
franta-hg@12
   554
otherwise) that contradict the conditions of this License, they do not
franta-hg@12
   555
excuse you from the conditions of this License.  If you cannot convey a
franta-hg@12
   556
covered work so as to satisfy simultaneously your obligations under this
franta-hg@12
   557
License and any other pertinent obligations, then as a consequence you may
franta-hg@12
   558
not convey it at all.  For example, if you agree to terms that obligate you
franta-hg@12
   559
to collect a royalty for further conveying from those to whom you convey
franta-hg@12
   560
the Program, the only way you could satisfy both those terms and this
franta-hg@12
   561
License would be to refrain entirely from conveying the Program.
franta-hg@12
   562
franta-hg@12
   563
\item Remote Network Interaction; Use with the GNU General Public License.
franta-hg@12
   564
franta-hg@12
   565
Notwithstanding any other provision of this License, if you modify the
franta-hg@12
   566
Program, your modified version must prominently offer all users interacting
franta-hg@12
   567
with it remotely through a computer network (if your version supports such
franta-hg@12
   568
interaction) an opportunity to receive the Corresponding Source of your
franta-hg@12

facilitating copying of software.  This Corresponding Source shall include
franta-hg@12
   572
the Corresponding Source for any work covered by version 3 of the GNU
franta-hg@12

franta-hg@12
   575
franta-hg@12
   576
Notwithstanding any other provision of this License, you have permission to
franta-hg@12
   577
link or combine any covered work with a work licensed under version 3 of
franta-hg@12
   578
the GNU General Public License into a single combined work, and to convey
franta-hg@12
   579
the resulting work.  The terms of this License will continue to apply to
franta-hg@12
   580
the part which is the covered work, but the work with which it is combined
franta-hg@12
   581
will remain governed by version 3 of the GNU General Public License.

\item Revised Versions of this License.
franta-hg@12
   584
franta-hg@12
   585
The Free Software Foundation may publish revised and/or new versions of
franta-hg@12
   586
the GNU Affero General Public License from time to time.  Such new versions will
franta-hg@12
   587
be similar in spirit to the present version, but may differ in detail to
franta-hg@12
   588
address new problems or concerns.
franta-hg@12
   589
franta-hg@12
   590
Each version is given a distinguishing version number.  If the
franta-hg@12
   591
Program specifies that a certain numbered version of the GNU Affero General
franta-hg@12
   592
Public License ``or any later version'' applies to it, you have the
franta-hg@12
   593
option of following the terms and conditions either of that numbered
franta-hg@12
   594
version or of any later version published by the Free Software
franta-hg@12
   595
Foundation.  If the Program does not specify a version number of the
franta-hg@12
   596
GNU Affero General Public License, you may choose any version ever published
franta-hg@12
   597
by the Free Software Foundation.
franta-hg@12
   598
franta-hg@12
   599
If the Program specifies that a proxy can decide which future
franta-hg@12
   600
versions of the GNU Affero General Public License can be used, that proxy's
franta-hg@12
   601
public statement of acceptance of a version permanently authorizes you
franta-hg@12
   602
to choose that version for the Program.
franta-hg@12
   603
franta-hg@12
   604
Later license versions may give you additional or different
franta-hg@12
   605
permissions.  However, no additional obligations are imposed on any
franta-hg@12
   606
author or copyright holder as a result of your choosing to follow a
franta-hg@12
   607
later version.

\begin{sloppypar}
franta-hg@12
   612
 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
franta-hg@12
   613
 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE
franta-hg@12
   614
 COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS''
franta-hg@12
   615
 WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
franta-hg@12
   616
 INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
franta-hg@12
   617
 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE
franta-hg@12
   618
 RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.
franta-hg@12
   619
 SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
franta-hg@12
   620
 NECESSARY SERVICING, REPAIR OR CORRECTION.

\item Limitation of Liability.
franta-hg@12
   624
franta-hg@12
   625
 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
franta-hg@12
   626
 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES
franta-hg@12
   627
 AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
franta-hg@12
   628
 DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
franta-hg@12
   629
 DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
franta-hg@12
   630
 (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
franta-hg@12
   631
 INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE
franta-hg@12
   632
 OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
franta-hg@12
   633
 HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
franta-hg@12
   634
 DAMAGES.

\item Interpretation of Sections 15 and 16.
franta-hg@12
   637
franta-hg@12
   638
If the disclaimer of warranty and limitation of liability provided
franta-hg@12
   639
above cannot be given local legal effect according to their terms,
franta-hg@12
   640
reviewing courts shall apply local law that most closely approximates
franta-hg@12
   641
an absolute waiver of all civil liability in connection with the
franta-hg@12
   642
Program, unless a warranty or assumption of liability accompanies a
franta-hg@12
   643
copy of the Program in return for a fee.

   651
franta-hg@12
   652
If you develop a new program, and you want it to be of the greatest
franta-hg@12
   653
possible use to the public, the best way to achieve this is to make it
franta-hg@12
   654
free software which everyone can redistribute and change under these terms.
franta-hg@12
   655
franta-hg@12
   656
To do so, attach the following notices to the program.  It is safest
franta-hg@12
   657
to attach them to the start of each source file to most effectively
franta-hg@12
   658
state the exclusion of warranty; and each file should have at least
franta-hg@12
   659
the ``copyright'' line and a pointer to where the full notice is found.

   683
franta-hg@12
   684
If your software can interact with users remotely through a computer
franta-hg@12
   685
network, you should also make sure that it provides a way for users to
franta-hg@12
   686
get its source.  For example, if your program is a web application, its
franta-hg@12
   687
interface could display a ``Source'' link that leads users to an archive
franta-hg@12
   688
of the code.  There are many ways you could offer source, and different
franta-hg@12
   689
solutions will be better for different programs; see section 13 for the
franta-hg@12
   690
specific requirements.
franta-hg@12
   691
franta-hg@12
   692
You should also get your employer (if you work as a programmer) or
franta-hg@12
   693
school, if any, to sign a ``copyright disclaimer'' for the program, if
franta-hg@12
   694
necessary.  For more information on this, and how to apply and follow
