                    GNU AFFERO GENERAL PUBLIC LICENSE
2 303 sjacqu01
                       Version 3, 19 November 2007
3 303 sjacqu01
4 303 sjacqu01
 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
5 303 sjacqu01
 Everyone is permitted to copy and distribute verbatim copies
6 303 sjacqu01
 of this license document, but changing it is not allowed.
7 303 sjacqu01
8 303 sjacqu01
                            Preamble
9 303 sjacqu01
10 303 sjacqu01
  The GNU Affero General Public License is a free, copyleft license for
11 303 sjacqu01
software and other kinds of works, specifically designed to ensure
12 303 sjacqu01
cooperation with the community in the case of network server software.
13 303 sjacqu01
14 303 sjacqu01
  The licenses for most software and other practical works are designed
15 303 sjacqu01
to take away your freedom to share and change the works.  By contrast,
16 303 sjacqu01
our General Public Licenses are intended to guarantee your freedom to
17 303 sjacqu01
share and change all versions of a program--to make sure it remains free
18 303 sjacqu01
software for all its users.
19 303 sjacqu01
20 303 sjacqu01
  When we speak of free software, we are referring to freedom, not
21 303 sjacqu01
price.  Our General Public Licenses are designed to make sure that you
22 303 sjacqu01
have the freedom to distribute copies of free software (and charge for
23 303 sjacqu01
them if you wish), that you receive source code or can get it if you
24 303 sjacqu01
want it, that you can change the software or use pieces of it in new
25 303 sjacqu01
free programs, and that you know you can do these things.
26 303 sjacqu01
27 303 sjacqu01
  Developers that use our General Public Licenses protect your rights
28 303 sjacqu01
with two steps: (1) assert copyright on the software, and (2) offer
29 303 sjacqu01
you this License which gives you legal permission to copy, distribute
30 303 sjacqu01
and/or modify the software.
31 303 sjacqu01
32 303 sjacqu01
  A secondary benefit of defending all users' freedom is that
33 303 sjacqu01
improvements made in alternate versions of the program, if they
34 303 sjacqu01
receive widespread use, become available for other developers to
35 303 sjacqu01
incorporate.  Many developers of free software are heartened and
36 303 sjacqu01
encouraged by the resulting cooperation.  However, in the case of
37 303 sjacqu01
software used on network servers, this result may fail to come about.
38 303 sjacqu01
The GNU General Public License permits making a modified version and
39 303 sjacqu01
letting the public access it on a server without ever releasing its
40 303 sjacqu01
source code to the public.
41 303 sjacqu01
42 303 sjacqu01
  The GNU Affero General Public License is designed specifically to
43 303 sjacqu01
ensure that, in such cases, the modified source code becomes available
44 303 sjacqu01
to the community.  It requires the operator of a network server to
45 303 sjacqu01
provide the source code of the modified version running there to the
46 303 sjacqu01
users of that server.  Therefore, public use of a modified version, on
47 303 sjacqu01
a publicly accessible server, gives the public access to the source
48 303 sjacqu01
code of the modified version.
49 303 sjacqu01
50 303 sjacqu01
  An older license, called the Affero General Public License and
51 303 sjacqu01
published by Affero, was designed to accomplish similar goals.  This is
52 303 sjacqu01
a different license, not a version of the Affero GPL, but Affero has
53 303 sjacqu01
released a new version of the Affero GPL which permits relicensing under
54 303 sjacqu01
this license.
55 303 sjacqu01
56 303 sjacqu01
  The precise terms and conditions for copying, distribution and
57 303 sjacqu01
modification follow.
58 303 sjacqu01
59 303 sjacqu01
                       TERMS AND CONDITIONS
60 303 sjacqu01
61 303 sjacqu01
  0. Definitions.
62 303 sjacqu01
63 303 sjacqu01
  "This License" refers to version 3 of the GNU Affero General Public License.
64 303 sjacqu01
65 303 sjacqu01
  "Copyright" also means copyright-like laws that apply to other kinds of
66 303 sjacqu01
works, such as semiconductor masks.
67 303 sjacqu01
68 303 sjacqu01
  "The Program" refers to any copyrightable work licensed under this
69 303 sjacqu01
License.  Each licensee is addressed as "you".  "Licensees" and
70 303 sjacqu01
"recipients" may be individuals or organizations.
71 303 sjacqu01
72 303 sjacqu01
  To "modify" a work means to copy from or adapt all or part of the work
73 303 sjacqu01
in a fashion requiring copyright permission, other than the making of an
74 303 sjacqu01
exact copy.  The resulting work is called a "modified version" of the
75 303 sjacqu01
earlier work or a work "based on" the earlier work.
76 303 sjacqu01
77 303 sjacqu01
  A "covered work" means either the unmodified Program or a work based
78 303 sjacqu01
on the Program.
79 303 sjacqu01
80 303 sjacqu01
  To "propagate" a work means to do anything with it that, without
81 303 sjacqu01
permission, would make you directly or secondarily liable for
82 303 sjacqu01
infringement under applicable copyright law, except executing it on a
83 303 sjacqu01
computer or modifying a private copy.  Propagation includes copying,
84 303 sjacqu01
distribution (with or without modification), making available to the
85 303 sjacqu01
public, and in some countries other activities as well.
86 303 sjacqu01
87 303 sjacqu01
  To "convey" a work means any kind of propagation that enables other
88 303 sjacqu01
parties to make or receive copies.  Mere interaction with a user through
89 303 sjacqu01
a computer network, with no transfer of a copy, is not conveying.
90 303 sjacqu01
91 303 sjacqu01
  An interactive user interface displays "Appropriate Legal Notices"
92 303 sjacqu01
to the extent that it includes a convenient and prominently visible
93 303 sjacqu01
feature that (1) displays an appropriate copyright notice, and (2)
94 303 sjacqu01
tells the user that there is no warranty for the work (except to the
95 303 sjacqu01
extent that warranties are provided), that licensees may convey the
96 303 sjacqu01
work under this License, and how to view a copy of this License.  If
97 303 sjacqu01
the interface presents a list of user commands or options, such as a
98 303 sjacqu01
menu, a prominent item in the list meets this criterion.
99 303 sjacqu01
100 303 sjacqu01
  1. Source Code.
101 303 sjacqu01
102 303 sjacqu01
  The "source code" for a work means the preferred form of the work
103 303 sjacqu01
for making modifications to it.  "Object code" means any non-source
104 303 sjacqu01
form of a work.
105 303 sjacqu01
106 303 sjacqu01
  A "Standard Interface" means an interface that either is an official
107 303 sjacqu01
standard defined by a recognized standards body, or, in the case of
108 303 sjacqu01
interfaces specified for a particular programming language, one that
109 303 sjacqu01
is widely used among developers working in that language.
110 303 sjacqu01
111 303 sjacqu01
  The "System Libraries" of an executable work include anything, other
112 303 sjacqu01
than the work as a whole, that (a) is included in the normal form of
113 303 sjacqu01
packaging a Major Component, but which is not part of that Major
114 303 sjacqu01
Component, and (b) serves only to enable use of the work with that
115 303 sjacqu01
Major Component, or to implement a Standard Interface for which an
116 303 sjacqu01
implementation is available to the public in source code form.  A
117 303 sjacqu01
"Major Component", in this context, means a major essential component
118 303 sjacqu01
(kernel, window system, and so on) of the specific operating system
119 303 sjacqu01
(if any) on which the executable work runs, or a compiler used to
120 303 sjacqu01
produce the work, or an object code interpreter used to run it.
121 303 sjacqu01
122 303 sjacqu01
  The "Corresponding Source" for a work in object code form means all
123 303 sjacqu01
the source code needed to generate, install, and (for an executable
124 303 sjacqu01
work) run the object code and to modify the work, including scripts to
125 303 sjacqu01
control those activities.  However, it does not include the work's
126 303 sjacqu01
System Libraries, or general-purpose tools or generally available free
127 303 sjacqu01
programs which are used unmodified in performing those activities but
128 303 sjacqu01
which are not part of the work.  For example, Corresponding Source
129 303 sjacqu01
includes interface definition files associated with source files for
130 303 sjacqu01
the work, and the source code for shared libraries and dynamically
131 303 sjacqu01
linked subprograms that the work is specifically designed to require,
132 303 sjacqu01
such as by intimate data communication or control flow between those
133 303 sjacqu01
subprograms and other parts of the work.
134 303 sjacqu01
135 303 sjacqu01
  The Corresponding Source need not include anything that users
136 303 sjacqu01
can regenerate automatically from other parts of the Corresponding
137 303 sjacqu01
Source.
138 303 sjacqu01
139 303 sjacqu01
  The Corresponding Source for a work in source code form is that
140 303 sjacqu01
same work.
141 303 sjacqu01
142 303 sjacqu01
  2. Basic Permissions.
143 303 sjacqu01
144 303 sjacqu01
  All rights granted under this License are granted for the term of
145 303 sjacqu01
copyright on the Program, and are irrevocable provided the stated
146 303 sjacqu01
conditions are met.  This License explicitly affirms your unlimited
147 303 sjacqu01
permission to run the unmodified Program.  The output from running a
148 303 sjacqu01
covered work is covered by this License only if the output, given its
149 303 sjacqu01
content, constitutes a covered work.  This License acknowledges your
150 303 sjacqu01
rights of fair use or other equivalent, as provided by copyright law.
151 303 sjacqu01
152 303 sjacqu01
  You may make, run and propagate covered works that you do not
153 303 sjacqu01
convey, without conditions so long as your license otherwise remains
154 303 sjacqu01
in force.  You may convey covered works to others for the sole purpose
155 303 sjacqu01
of having them make modifications exclusively for you, or provide you
156 303 sjacqu01
with facilities for running those works, provided that you comply with
157 303 sjacqu01
the terms of this License in conveying all material for which you do
158 303 sjacqu01
not control copyright.  Those thus making or running the covered works
159 303 sjacqu01
for you must do so exclusively on your behalf, under your direction
160 303 sjacqu01
and control, on terms that prohibit them from making any copies of
161 303 sjacqu01
your copyrighted material outside their relationship with you.
162 303 sjacqu01
163 303 sjacqu01
  Conveying under any other circumstances is permitted solely under
164 303 sjacqu01
the conditions stated below.  Sublicensing is not allowed; section 10
165 303 sjacqu01
makes it unnecessary.
166 303 sjacqu01
167 303 sjacqu01
  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
168 303 sjacqu01
169 303 sjacqu01
  No covered work shall be deemed part of an effective technological
170 303 sjacqu01
measure under any applicable law fulfilling obligations under article
171 303 sjacqu01
11 of the WIPO copyright treaty adopted on 20 December 1996, or
172 303 sjacqu01
similar laws prohibiting or restricting circumvention of such
173 303 sjacqu01
measures.
174 303 sjacqu01
175 303 sjacqu01
  When you convey a covered work, you waive any legal power to forbid
176 303 sjacqu01
circumvention of technological measures to the extent such circumvention
177 303 sjacqu01
is effected by exercising rights under this License with respect to
178 303 sjacqu01
the covered work, and you disclaim any intention to limit operation or
179 303 sjacqu01
modification of the work as a means of enforcing, against the work's
180 303 sjacqu01
users, your or third parties' legal rights to forbid circumvention of
181 303 sjacqu01
technological measures.
182 303 sjacqu01
183 303 sjacqu01
  4. Conveying Verbatim Copies.
184 303 sjacqu01
185 303 sjacqu01
  You may convey verbatim copies of the Program's source code as you
186 303 sjacqu01
receive it, in any medium, provided that you conspicuously and
187 303 sjacqu01
appropriately publish on each copy an appropriate copyright notice;
188 303 sjacqu01
keep intact all notices stating that this License and any
189 303 sjacqu01
non-permissive terms added in accord with section 7 apply to the code;
190 303 sjacqu01
keep intact all notices of the absence of any warranty; and give all
191 303 sjacqu01
recipients a copy of this License along with the Program.
192 303 sjacqu01
193 303 sjacqu01
  You may charge any price or no price for each copy that you convey,
194 303 sjacqu01
and you may offer support or warranty protection for a fee.
195 303 sjacqu01
196 303 sjacqu01
  5. Conveying Modified Source Versions.
197 303 sjacqu01
198 303 sjacqu01
  You may convey a work based on the Program, or the modifications to
199 303 sjacqu01
produce it from the Program, in the form of source code under the
200 303 sjacqu01
terms of section 4, provided that you also meet all of these conditions:
201 303 sjacqu01
202 303 sjacqu01
    a) The work must carry prominent notices stating that you modified
203 303 sjacqu01
    it, and giving a relevant date.
204 303 sjacqu01
205 303 sjacqu01
    b) The work must carry prominent notices stating that it is
206 303 sjacqu01
    released under this License and any conditions added under section
207 303 sjacqu01
    7.  This requirement modifies the requirement in section 4 to
208 303 sjacqu01
    "keep intact all notices".
209 303 sjacqu01
210 303 sjacqu01
    c) You must license the entire work, as a whole, under this
211 303 sjacqu01
    License to anyone who comes into possession of a copy.  This
212 303 sjacqu01
    License will therefore apply, along with any applicable section 7
213 303 sjacqu01
    additional terms, to the whole of the work, and all its parts,
214 303 sjacqu01
    regardless of how they are packaged.  This License gives no
215 303 sjacqu01
    permission to license the work in any other way, but it does not
216 303 sjacqu01
    invalidate such permission if you have separately received it.
217 303 sjacqu01
218 303 sjacqu01
    d) If the work has interactive user interfaces, each must display
219 303 sjacqu01
    Appropriate Legal Notices; however, if the Program has interactive
220 303 sjacqu01
    interfaces that do not display Appropriate Legal Notices, your
221 303 sjacqu01
    work need not make them do so.
222 303 sjacqu01
223 303 sjacqu01
  A compilation of a covered work with other separate and independent
224 303 sjacqu01
works, which are not by their nature extensions of the covered work,
225 303 sjacqu01
and which are not combined with it such as to form a larger program,
226 303 sjacqu01
in or on a volume of a storage or distribution medium, is called an
227 303 sjacqu01
"aggregate" if the compilation and its resulting copyright are not
228 303 sjacqu01
used to limit the access or legal rights of the compilation's users
229 303 sjacqu01
beyond what the individual works permit.  Inclusion of a covered work
230 303 sjacqu01
in an aggregate does not cause this License to apply to the other
231 303 sjacqu01
parts of the aggregate.
232 303 sjacqu01
233 303 sjacqu01
  6. Conveying Non-Source Forms.
234 303 sjacqu01
235 303 sjacqu01
  You may convey a covered work in object code form under the terms
236 303 sjacqu01
of sections 4 and 5, provided that you also convey the
237 303 sjacqu01
machine-readable Corresponding Source under the terms of this License,
238 303 sjacqu01
in one of these ways:
239 303 sjacqu01
240 303 sjacqu01
    a) Convey the object code in, or embodied in, a physical product
241 303 sjacqu01
    (including a physical distribution medium), accompanied by the
242 303 sjacqu01
    Corresponding Source fixed on a durable physical medium
243 303 sjacqu01
    customarily used for software interchange.
244 303 sjacqu01
245 303 sjacqu01
    b) Convey the object code in, or embodied in, a physical product
246 303 sjacqu01
    (including a physical distribution medium), accompanied by a
247 303 sjacqu01
    written offer, valid for at least three years and valid for as
248 303 sjacqu01
    long as you offer spare parts or customer support for that product
249 303 sjacqu01
    model, to give anyone who possesses the object code either (1) a
250 303 sjacqu01
    copy of the Corresponding Source for all the software in the
251 303 sjacqu01
    product that is covered by this License, on a durable physical
252 303 sjacqu01
    medium customarily used for software interchange, for a price no
253 303 sjacqu01
    more than your reasonable cost of physically performing this
254 303 sjacqu01
    conveying of source, or (2) access to copy the
255 303 sjacqu01
    Corresponding Source from a network server at no charge.
256 303 sjacqu01
257 303 sjacqu01
    c) Convey individual copies of the object code with a copy of the
258 303 sjacqu01
    written offer to provide the Corresponding Source.  This
259 303 sjacqu01
    alternative is allowed only occasionally and noncommercially, and
260 303 sjacqu01
    only if you received the object code with such an offer, in accord
261 303 sjacqu01
    with subsection 6b.
262 303 sjacqu01
263 303 sjacqu01
    d) Convey the object code by offering access from a designated
264 303 sjacqu01
    place (gratis or for a charge), and offer equivalent access to the
265 303 sjacqu01
    Corresponding Source in the same way through the same place at no
266 303 sjacqu01
    further charge.  You need not require recipients to copy the
267 303 sjacqu01
    Corresponding Source along with the object code.  If the place to
268 303 sjacqu01
    copy the object code is a network server, the Corresponding Source
269 303 sjacqu01
    may be on a different server (operated by you or a third party)
270 303 sjacqu01
    that supports equivalent copying facilities, provided you maintain
271 303 sjacqu01
    clear directions next to the object code saying where to find the
272 303 sjacqu01
    Corresponding Source.  Regardless of what server hosts the
273 303 sjacqu01
    Corresponding Source, you remain obligated to ensure that it is
274 303 sjacqu01
    available for as long as needed to satisfy these requirements.
275 303 sjacqu01
276 303 sjacqu01
    e) Convey the object code using peer-to-peer transmission, provided
277 303 sjacqu01
    you inform other peers where the object code and Corresponding
278 303 sjacqu01
    Source of the work are being offered to the general public at no
279 303 sjacqu01
    charge under subsection 6d.
280 303 sjacqu01
281 303 sjacqu01
  A separable portion of the object code, whose source code is excluded
282 303 sjacqu01
from the Corresponding Source as a System Library, need not be
283 303 sjacqu01
included in conveying the object code work.
284 303 sjacqu01
285 303 sjacqu01
  A "User Product" is either (1) a "consumer product", which means any
286 303 sjacqu01
tangible personal property which is normally used for personal, family,
287 303 sjacqu01
or household purposes, or (2) anything designed or sold for incorporation
288 303 sjacqu01
into a dwelling.  In determining whether a product is a consumer product,
289 303 sjacqu01
doubtful cases shall be resolved in favor of coverage.  For a particular
290 303 sjacqu01
product received by a particular user, "normally used" refers to a
291 303 sjacqu01
typical or common use of that class of product, regardless of the status
292 303 sjacqu01
of the particular user or of the way in which the particular user
293 303 sjacqu01
actually uses, or expects or is expected to use, the product.  A product
294 303 sjacqu01
is a consumer product regardless of whether the product has substantial
295 303 sjacqu01
commercial, industrial or non-consumer uses, unless such uses represent
296 303 sjacqu01
the only significant mode of use of the product.
297 303 sjacqu01
298 303 sjacqu01
  "Installation Information" for a User Product means any methods,
299 303 sjacqu01
procedures, authorization keys, or other information required to install
300 303 sjacqu01
and execute modified versions of a covered work in that User Product from
301 303 sjacqu01
a modified version of its Corresponding Source.  The information must
302 303 sjacqu01
suffice to ensure that the continued functioning of the modified object
303 303 sjacqu01
code is in no case prevented or interfered with solely because
304 303 sjacqu01
modification has been made.
305 303 sjacqu01
306 303 sjacqu01
  If you convey an object code work under this section in, or with, or
307 303 sjacqu01
specifically for use in, a User Product, and the conveying occurs as
308 303 sjacqu01
part of a transaction in which the right of possession and use of the
309 303 sjacqu01
User Product is transferred to the recipient in perpetuity or for a
310 303 sjacqu01
fixed term (regardless of how the transaction is characterized), the
311 303 sjacqu01
Corresponding Source conveyed under this section must be accompanied
312 303 sjacqu01
by the Installation Information.  But this requirement does not apply
313 303 sjacqu01
if neither you nor any third party retains the ability to install
314 303 sjacqu01
modified object code on the User Product (for example, the work has
315 303 sjacqu01
been installed in ROM).
316 303 sjacqu01
317 303 sjacqu01
  The requirement to provide Installation Information does not include a
318 303 sjacqu01
requirement to continue to provide support service, warranty, or updates
319 303 sjacqu01
for a work that has been modified or installed by the recipient, or for
320 303 sjacqu01
the User Product in which it has been modified or installed.  Access to a
321 303 sjacqu01
network may be denied when the modification itself materially and
322 303 sjacqu01
adversely affects the operation of the network or violates the rules and
323 303 sjacqu01
protocols for communication across the network.
324 303 sjacqu01
325 303 sjacqu01
  Corresponding Source conveyed, and Installation Information provided,
326 303 sjacqu01
in accord with this section must be in a format that is publicly
327 303 sjacqu01
documented (and with an implementation available to the public in
328 303 sjacqu01
source code form), and must require no special password or key for
329 303 sjacqu01
unpacking, reading or copying.
330 303 sjacqu01
331 303 sjacqu01
  7. Additional Terms.
332 303 sjacqu01
333 303 sjacqu01
  "Additional permissions" are terms that supplement the terms of this
334 303 sjacqu01
License by making exceptions from one or more of its conditions.
335 303 sjacqu01
Additional permissions that are applicable to the entire Program shall
336 303 sjacqu01
be treated as though they were included in this License, to the extent
337 303 sjacqu01
that they are valid under applicable law.  If additional permissions
338 303 sjacqu01
apply only to part of the Program, that part may be used separately
339 303 sjacqu01
under those permissions, but the entire Program remains governed by
340 303 sjacqu01
this License without regard to the additional permissions.
341 303 sjacqu01
342 303 sjacqu01
  When you convey a copy of a covered work, you may at your option
343 303 sjacqu01
remove any additional permissions from that copy, or from any part of
344 303 sjacqu01
it.  (Additional permissions may be written to require their own
345 303 sjacqu01
removal in certain cases when you modify the work.)  You may place
346 303 sjacqu01
additional permissions on material, added by you to a covered work,
347 303 sjacqu01
for which you have or can give appropriate copyright permission.
348 303 sjacqu01
349 303 sjacqu01
  Notwithstanding any other provision of this License, for material you
350 303 sjacqu01
add to a covered work, you may (if authorized by the copyright holders of
351 303 sjacqu01
that material) supplement the terms of this License with terms:
352 303 sjacqu01
353 303 sjacqu01
    a) Disclaiming warranty or limiting liability differently from the
354 303 sjacqu01
    terms of sections 15 and 16 of this License; or
355 303 sjacqu01
356 303 sjacqu01
    b) Requiring preservation of specified reasonable legal notices or
357 303 sjacqu01
    author attributions in that material or in the Appropriate Legal
358 303 sjacqu01
    Notices displayed by works containing it; or
359 303 sjacqu01
360 303 sjacqu01
    c) Prohibiting misrepresentation of the origin of that material, or
361 303 sjacqu01
    requiring that modified versions of such material be marked in
362 303 sjacqu01
    reasonable ways as different from the original version; or
363 303 sjacqu01
364 303 sjacqu01
    d) Limiting the use for publicity purposes of names of licensors or
365 303 sjacqu01
    authors of the material; or
366 303 sjacqu01
367 303 sjacqu01
    e) Declining to grant rights under trademark law for use of some
368 303 sjacqu01
    trade names, trademarks, or service marks; or
369 303 sjacqu01
370 303 sjacqu01
    f) Requiring indemnification of licensors and authors of that
371 303 sjacqu01
    material by anyone who conveys the material (or modified versions of
372 303 sjacqu01
    it) with contractual assumptions of liability to the recipient, for
373 303 sjacqu01
    any liability that these contractual assumptions directly impose on
374 303 sjacqu01
    those licensors and authors.
375 303 sjacqu01
376 303 sjacqu01
  All other non-permissive additional terms are considered "further
377 303 sjacqu01
restrictions" within the meaning of section 10.  If the Program as you
378 303 sjacqu01
received it, or any part of it, contains a notice stating that it is
379 303 sjacqu01
governed by this License along with a term that is a further
380 303 sjacqu01
restriction, you may remove that term.  If a license document contains
381 303 sjacqu01
a further restriction but permits relicensing or conveying under this
382 303 sjacqu01
License, you may add to a covered work material governed by the terms
383 303 sjacqu01
of that license document, provided that the further restriction does
384 303 sjacqu01
not survive such relicensing or conveying.
385 303 sjacqu01
386 303 sjacqu01
  If you add terms to a covered work in accord with this section, you
387 303 sjacqu01
must place, in the relevant source files, a statement of the
388 303 sjacqu01
additional terms that apply to those files, or a notice indicating
389 303 sjacqu01
where to find the applicable terms.
390 303 sjacqu01
391 303 sjacqu01
  Additional terms, permissive or non-permissive, may be stated in the
392 303 sjacqu01
form of a separately written license, or stated as exceptions;
393 303 sjacqu01
the above requirements apply either way.
394 303 sjacqu01
395 303 sjacqu01
  8. Termination.
396 303 sjacqu01
397 303 sjacqu01
  You may not propagate or modify a covered work except as expressly
398 303 sjacqu01
provided under this License.  Any attempt otherwise to propagate or
399 303 sjacqu01
modify it is void, and will automatically terminate your rights under
400 303 sjacqu01
this License (including any patent licenses granted under the third
401 303 sjacqu01
paragraph of section 11).
402 303 sjacqu01
403 303 sjacqu01
  However, if you cease all violation of this License, then your
404 303 sjacqu01
license from a particular copyright holder is reinstated (a)
405 303 sjacqu01
provisionally, unless and until the copyright holder explicitly and
406 303 sjacqu01
finally terminates your license, and (b) permanently, if the copyright
407 303 sjacqu01
holder fails to notify you of the violation by some reasonable means
408 303 sjacqu01
prior to 60 days after the cessation.
409 303 sjacqu01
410 303 sjacqu01
  Moreover, your license from a particular copyright holder is
411 303 sjacqu01
reinstated permanently if the copyright holder notifies you of the
412 303 sjacqu01
violation by some reasonable means, this is the first time you have
413 303 sjacqu01
received notice of violation of this License (for any work) from that
414 303 sjacqu01
copyright holder, and you cure the violation prior to 30 days after
415 303 sjacqu01
your receipt of the notice.
416 303 sjacqu01
417 303 sjacqu01
  Termination of your rights under this section does not terminate the
418 303 sjacqu01
licenses of parties who have received copies or rights from you under
419 303 sjacqu01
this License.  If your rights have been terminated and not permanently
420 303 sjacqu01
reinstated, you do not qualify to receive new licenses for the same
421 303 sjacqu01
material under section 10.
422 303 sjacqu01
423 303 sjacqu01
  9. Acceptance Not Required for Having Copies.
424 303 sjacqu01
425 303 sjacqu01
  You are not required to accept this License in order to receive or
426 303 sjacqu01
run a copy of the Program.  Ancillary propagation of a covered work
427 303 sjacqu01
occurring solely as a consequence of using peer-to-peer transmission
428 303 sjacqu01
to receive a copy likewise does not require acceptance.  However,
429 303 sjacqu01
nothing other than this License grants you permission to propagate or
430 303 sjacqu01
modify any covered work.  These actions infringe copyright if you do
431 303 sjacqu01
not accept this License.  Therefore, by modifying or propagating a
432 303 sjacqu01
covered work, you indicate your acceptance of this License to do so.
433 303 sjacqu01
434 303 sjacqu01
  10. Automatic Licensing of Downstream Recipients.
435 303 sjacqu01
436 303 sjacqu01
  Each time you convey a covered work, the recipient automatically
437 303 sjacqu01
receives a license from the original licensors, to run, modify and
438 303 sjacqu01
propagate that work, subject to this License.  You are not responsible
439 303 sjacqu01
for enforcing compliance by third parties with this License.
440 303 sjacqu01
441 303 sjacqu01
  An "entity transaction" is a transaction transferring control of an
442 303 sjacqu01
organization, or substantially all assets of one, or subdividing an
443 303 sjacqu01
organization, or merging organizations.  If propagation of a covered
444 303 sjacqu01
work results from an entity transaction, each party to that
445 303 sjacqu01
transaction who receives a copy of the work also receives whatever
446 303 sjacqu01
licenses to the work the party's predecessor in interest had or could
447 303 sjacqu01
give under the previous paragraph, plus a right to possession of the
448 303 sjacqu01
Corresponding Source of the work from the predecessor in interest, if
449 303 sjacqu01
the predecessor has it or can get it with reasonable efforts.
450 303 sjacqu01
451 303 sjacqu01
  You may not impose any further restrictions on the exercise of the
452 303 sjacqu01
rights granted or affirmed under this License.  For example, you may
453 303 sjacqu01
not impose a license fee, royalty, or other charge for exercise of
454 303 sjacqu01
rights granted under this License, and you may not initiate litigation
455 303 sjacqu01
(including a cross-claim or counterclaim in a lawsuit) alleging that
456 303 sjacqu01
any patent claim is infringed by making, using, selling, offering for
457 303 sjacqu01
sale, or importing the Program or any portion of it.
458 303 sjacqu01
459 303 sjacqu01
  11. Patents.
460 303 sjacqu01
461 303 sjacqu01
  A "contributor" is a copyright holder who authorizes use under this
462 303 sjacqu01
License of the Program or a work on which the Program is based.  The
463 303 sjacqu01
work thus licensed is called the contributor's "contributor version".
464 303 sjacqu01
465 303 sjacqu01
  A contributor's "essential patent claims" are all patent claims
466 303 sjacqu01
owned or controlled by the contributor, whether already acquired or
467 303 sjacqu01
hereafter acquired, that would be infringed by some manner, permitted
468 303 sjacqu01
by this License, of making, using, or selling its contributor version,
469 303 sjacqu01
but do not include claims that would be infringed only as a
470 303 sjacqu01
consequence of further modification of the contributor version.  For
471 303 sjacqu01
purposes of this definition, "control" includes the right to grant
472 303 sjacqu01
patent sublicenses in a manner consistent with the requirements of
473 303 sjacqu01
this License.
474 303 sjacqu01
475 303 sjacqu01
  Each contributor grants you a non-exclusive, worldwide, royalty-free
476 303 sjacqu01
patent license under the contributor's essential patent claims, to
477 303 sjacqu01
make, use, sell, offer for sale, import and otherwise run, modify and
478 303 sjacqu01
propagate the contents of its contributor version.
479 303 sjacqu01
480 303 sjacqu01
  In the following three paragraphs, a "patent license" is any express
481 303 sjacqu01
agreement or commitment, however denominated, not to enforce a patent
482 303 sjacqu01
(such as an express permission to practice a patent or covenant not to
483 303 sjacqu01
sue for patent infringement).  To "grant" such a patent license to a
484 303 sjacqu01
party means to make such an agreement or commitment not to enforce a
485 303 sjacqu01
patent against the party.
486 303 sjacqu01
487 303 sjacqu01
  If you convey a covered work, knowingly relying on a patent license,
488 303 sjacqu01
and the Corresponding Source of the work is not available for anyone
489 303 sjacqu01
to copy, free of charge and under the terms of this License, through a
490 303 sjacqu01
publicly available network server or other readily accessible means,
491 303 sjacqu01
then you must either (1) cause the Corresponding Source to be so
492 303 sjacqu01
available, or (2) arrange to deprive yourself of the benefit of the
493 303 sjacqu01
patent license for this particular work, or (3) arrange, in a manner
494 303 sjacqu01
consistent with the requirements of this License, to extend the patent
495 303 sjacqu01
license to downstream recipients.  "Knowingly relying" means you have
496 303 sjacqu01
actual knowledge that, but for the patent license, your conveying the
497 303 sjacqu01
covered work in a country, or your recipient's use of the covered work
498 303 sjacqu01
in a country, would infringe one or more identifiable patents in that
499 303 sjacqu01
country that you have reason to believe are valid.
500 303 sjacqu01
501 303 sjacqu01
  If, pursuant to or in connection with a single transaction or
502 303 sjacqu01
arrangement, you convey, or propagate by procuring conveyance of, a
503 303 sjacqu01
covered work, and grant a patent license to some of the parties
504 303 sjacqu01
receiving the covered work authorizing them to use, propagate, modify
505 303 sjacqu01
or convey a specific copy of the covered work, then the patent license
506 303 sjacqu01
you grant is automatically extended to all recipients of the covered
507 303 sjacqu01
work and works based on it.
508 303 sjacqu01
509 303 sjacqu01
  A patent license is "discriminatory" if it does not include within
510 303 sjacqu01
the scope of its coverage, prohibits the exercise of, or is
511 303 sjacqu01
conditioned on the non-exercise of one or more of the rights that are
512 303 sjacqu01
specifically granted under this License.  You may not convey a covered
513 303 sjacqu01
work if you are a party to an arrangement with a third party that is
514 303 sjacqu01
in the business of distributing software, under which you make payment
515 303 sjacqu01
to the third party based on the extent of your activity of conveying
516 303 sjacqu01
the work, and under which the third party grants, to any of the
517 303 sjacqu01
parties who would receive the covered work from you, a discriminatory
518 303 sjacqu01
patent license (a) in connection with copies of the covered work
519 303 sjacqu01
conveyed by you (or copies made from those copies), or (b) primarily
520 303 sjacqu01
for and in connection with specific products or compilations that
521 303 sjacqu01
contain the covered work, unless you entered into that arrangement,
522 303 sjacqu01
or that patent license was granted, prior to 28 March 2007.
523 303 sjacqu01
524 303 sjacqu01
  Nothing in this License shall be construed as excluding or limiting
525 303 sjacqu01
any implied license or other defenses to infringement that may
526 303 sjacqu01
otherwise be available to you under applicable patent law.
527 303 sjacqu01
528 303 sjacqu01
  12. No Surrender of Others' Freedom.
529 303 sjacqu01
530 303 sjacqu01
  If conditions are imposed on you (whether by court order, agreement or
531 303 sjacqu01
otherwise) that contradict the conditions of this License, they do not
532 303 sjacqu01
excuse you from the conditions of this License.  If you cannot convey a
533 303 sjacqu01
covered work so as to satisfy simultaneously your obligations under this
534 303 sjacqu01
License and any other pertinent obligations, then as a consequence you may
535 303 sjacqu01
not convey it at all.  For example, if you agree to terms that obligate you
536 303 sjacqu01
to collect a royalty for further conveying from those to whom you convey
537 303 sjacqu01
the Program, the only way you could satisfy both those terms and this
538 303 sjacqu01
License would be to refrain entirely from conveying the Program.
539 303 sjacqu01
540 303 sjacqu01
  13. Remote Network Interaction; Use with the GNU General Public License.
541 303 sjacqu01
542 303 sjacqu01
  Notwithstanding any other provision of this License, if you modify the
543 303 sjacqu01
Program, your modified version must prominently offer all users
544 303 sjacqu01
interacting with it remotely through a computer network (if your version
545 303 sjacqu01
supports such interaction) an opportunity to receive the Corresponding
546 303 sjacqu01
Source of your version by providing access to the Corresponding Source
547 303 sjacqu01
from a network server at no charge, through some standard or customary
548 303 sjacqu01
means of facilitating copying of software.  This Corresponding Source
549 303 sjacqu01
shall include the Corresponding Source for any work covered by version 3
550 303 sjacqu01
of the GNU General Public License that is incorporated pursuant to the
551 303 sjacqu01
following paragraph.
552 303 sjacqu01
553 303 sjacqu01
  Notwithstanding any other provision of this License, you have
554 303 sjacqu01
permission to link or combine any covered work with a work licensed
555 303 sjacqu01
under version 3 of the GNU General Public License into a single
556 303 sjacqu01
combined work, and to convey the resulting work.  The terms of this
557 303 sjacqu01
License will continue to apply to the part which is the covered work,
558 303 sjacqu01
but the work with which it is combined will remain governed by version
559 303 sjacqu01
3 of the GNU General Public License.
560 303 sjacqu01
561 303 sjacqu01
  14. Revised Versions of this License.
562 303 sjacqu01
563 303 sjacqu01
  The Free Software Foundation may publish revised and/or new versions of
564 303 sjacqu01
the GNU Affero General Public License from time to time.  Such new versions
565 303 sjacqu01
will be similar in spirit to the present version, but may differ in detail to
566 303 sjacqu01
address new problems or concerns.
567 303 sjacqu01
568 303 sjacqu01
  Each version is given a distinguishing version number.  If the
569 303 sjacqu01
Program specifies that a certain numbered version of the GNU Affero General
570 303 sjacqu01
Public License "or any later version" applies to it, you have the
571 303 sjacqu01
option of following the terms and conditions either of that numbered
572 303 sjacqu01
version or of any later version published by the Free Software
573 303 sjacqu01
Foundation.  If the Program does not specify a version number of the
574 303 sjacqu01
GNU Affero General Public License, you may choose any version ever published
575 303 sjacqu01
by the Free Software Foundation.
576 303 sjacqu01
577 303 sjacqu01
  If the Program specifies that a proxy can decide which future
578 303 sjacqu01
versions of the GNU Affero General Public License can be used, that proxy's
579 303 sjacqu01
public statement of acceptance of a version permanently authorizes you
580 303 sjacqu01
to choose that version for the Program.
581 303 sjacqu01
582 303 sjacqu01
  Later license versions may give you additional or different
583 303 sjacqu01
permissions.  However, no additional obligations are imposed on any
584 303 sjacqu01
author or copyright holder as a result of your choosing to follow a
585 303 sjacqu01
later version.
586 303 sjacqu01
587 303 sjacqu01
  15. Disclaimer of Warranty.
588 303 sjacqu01
589 303 sjacqu01
  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
590 303 sjacqu01
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
591 303 sjacqu01
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
592 303 sjacqu01
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
593 303 sjacqu01
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
594 303 sjacqu01
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
595 303 sjacqu01
IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
596 303 sjacqu01
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
597 303 sjacqu01
598 303 sjacqu01
  16. Limitation of Liability.
599 303 sjacqu01
600 303 sjacqu01
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING

WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
602 303 sjacqu01
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
603 303 sjacqu01
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
604 303 sjacqu01
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
605 303 sjacqu01
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
606 303 sjacqu01
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
607 303 sjacqu01
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
608 303 sjacqu01
SUCH DAMAGES.

612 303 sjacqu01
  If the disclaimer of warranty and limitation of liability provided
613 303 sjacqu01
above cannot be given local legal effect according to their terms,
614 303 sjacqu01
reviewing courts shall apply local law that most closely approximates
615 303 sjacqu01
an absolute waiver of all civil liability in connection with the
616 303 sjacqu01
Program, unless a warranty or assumption of liability accompanies a
617 303 sjacqu01
copy of the Program in return for a fee.

            How to Apply These Terms to Your New Programs
622 303 sjacqu01
623 303 sjacqu01
  If you develop a new program, and you want it to be of the greatest
624 303 sjacqu01
possible use to the public, the best way to achieve this is to make it
625 303 sjacqu01
free software which everyone can redistribute and change under these terms.
626 303 sjacqu01
627 303 sjacqu01
  To do so, attach the following notices to the program.  It is safest
628 303 sjacqu01
to attach them to the start of each source file to most effectively
629 303 sjacqu01
state the exclusion of warranty; and each file should have at least
630 303 sjacqu01
the "copyright" line and a pointer to where the full notice is found.
631 303 sjacqu01
632 303 sjacqu01
    <one line to give the program's name and a brief idea of what it does.>

649 303 sjacqu01
650 303 sjacqu01
  If your software can interact with users remotely through a computer
651 303 sjacqu01
network, you should also make sure that it provides a way for users to
652 303 sjacqu01
get its source.  For example, if your program is a web application, its
653 303 sjacqu01
interface could display a "Source" link that leads users to an archive
654 303 sjacqu01
of the code.  There are many ways you could offer source, and different
655 303 sjacqu01
solutions will be better for different programs; see section 13 for the
656 303 sjacqu01
specific requirements.
657 303 sjacqu01
658 303 sjacqu01
  You should also get your employer (if you work as a programmer) or school,
659 303 sjacqu01
if any, to sign a "copyright disclaimer" for the program, if necessary.
