                       Version 3, 29 June 2007
3 293 sjacqu01

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

  If the disclaimer of warranty and limitation of liability provided
615 293 sjacqu01
above cannot be given local legal effect according to their terms,
616 293 sjacqu01
reviewing courts shall apply local law that most closely approximates
617 293 sjacqu01
an absolute waiver of all civil liability in connection with the
618 293 sjacqu01
Program, unless a warranty or assumption of liability accompanies a
619 293 sjacqu01
copy of the Program in return for a fee.

            How to Apply These Terms to Your New Programs
624 293 sjacqu01
625 293 sjacqu01
  If you develop a new program, and you want it to be of the greatest
626 293 sjacqu01
possible use to the public, the best way to achieve this is to make it
627 293 sjacqu01
free software which everyone can redistribute and change under these terms.
628 293 sjacqu01
629 293 sjacqu01
  To do so, attach the following notices to the program.  It is safest
630 293 sjacqu01
to attach them to the start of each source file to most effectively
631 293 sjacqu01
state the exclusion of warranty; and each file should have at least
632 293 sjacqu01
the "copyright" line and a pointer to where the full notice is found.
633 293 sjacqu01
634 293 sjacqu01
    <one line to give the program's name and a brief idea of what it does.>

643 293 sjacqu01
    but WITHOUT ANY WARRANTY; without even the implied warranty of

    You should have received a copy of the GNU General Public License
648 293 sjacqu01

649 293 sjacqu01
650 293 sjacqu01
Also add information on how to contact you by electronic and paper mail.
651 293 sjacqu01
652 293 sjacqu01
  If the program does terminal interaction, make it output a short
653 293 sjacqu01
notice like this when it starts in an interactive mode:
654 293 sjacqu01
655 293 sjacqu01
    <program>  Copyright (C) <year>  <name of author>
656 293 sjacqu01
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
657 293 sjacqu01
    This is free software, and you are welcome to redistribute it
658 293 sjacqu01
    under certain conditions; type `show c' for details.
659 293 sjacqu01
660 293 sjacqu01
The hypothetical commands `show w' and `show c' should show the appropriate
661 293 sjacqu01
parts of the General Public License.  Of course, your program's commands
662 293 sjacqu01
might be different; for a GUI interface, you would use an "about box".
663 293 sjacqu01
664 293 sjacqu01
  You should also get your employer (if you work as a programmer) or school,
665 293 sjacqu01
if any, to sign a "copyright disclaimer" for the program, if necessary.

  The GNU General Public License does not permit incorporating your program
670 293 sjacqu01
into proprietary programs.  If your program is a subroutine library, you
671 293 sjacqu01
may consider it more useful to permit linking proprietary applications with
672 293 sjacqu01
the library.  If this is what you want to do, use the GNU Lesser General
673 293 sjacqu01
Public License instead of this License.  But first, please read
