16	<p>Preliminary notes:</p>
17
18	<p style='text-align:justify'>1) The majority of the code in
19	the VirtualBox base package is licensed under the GNU General Public License,
20	version 3 (GPL). VirtualBox contains many components developed by Oracle and
21	various third parties. The license for each component is located in the
22	licensing documentation and/or in the component's source code.</p>
23
24	<p style='text-align:justify'>2) As an exception to the reciprocal
25	license obligations of the GPL listed below, you may use any VirtualBox header
26	file that is marked by Oracle as licensed under both the GPL and the Common
27	Development and Distribution License version 1.0 (CDDL) to invoke the
28	unmodified VirtualBox libraries. In other words, calling such a multi-licensed
29	interface by dynamically linking to the unmodified VirtualBox libraries is
30	considered a normal use of VirtualBox and does not turn the calling code into a
31	derived work of VirtualBox. In particular, this applies to code that wants to
32	extend VirtualBox by way of the Extension Pack mechanism declared in the
33	ExtPack.h header file.</p>
34
35	<p style='text-align:justify'>3) Whoever creates or distributes
36	a derived work based on VirtualBox is not obligated to grant the above
37	exceptions for such a version. The GPL permits you to release a modified
38	version without the above exception; in addition, Oracle hereby also allows you
39	to release a modified version which carries forward these exceptions.</p>

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

730	contact you by electronic and paper mail.</p>
731

752
753	<p style='text-align:justify'>You should also get your employer
754	(if you work as a programmer) or school, if any, to sign a “copyright
