1	+	### GNU GENERAL PUBLIC LICENSE
2	+
3	+	Version 3, 29 June 2007
4	+
5	+	Copyright (C) 2007 Free Software Foundation, Inc.
6	+	<https://fsf.org/>
7	+
8	+	Everyone is permitted to copy and distribute verbatim copies of this
9	+	license document, but changing it is not allowed.
10	+
11	+	### Preamble
12	+
13	+	The GNU General Public License is a free, copyleft license for
14	+	software and other kinds of works.
15	+
16	+	The licenses for most software and other practical works are designed
17	+	to take away your freedom to share and change the works. By contrast,
18	+	the GNU General Public License is intended to guarantee your freedom
19	+	to share and change all versions of a program--to make sure it remains
20	+	free software for all its users. We, the Free Software Foundation, use
21	+	the GNU General Public License for most of our software; it applies
22	+	also to any other work released this way by its authors. You can apply
23	+	it to your programs, too.
24	+
25	+	When we speak of free software, we are referring to freedom, not
26	+	price. Our General Public Licenses are designed to make sure that you
27	+	have the freedom to distribute copies of free software (and charge for
28	+	them if you wish), that you receive source code or can get it if you
29	+	want it, that you can change the software or use pieces of it in new
30	+	free programs, and that you know you can do these things.
31	+
32	+	To protect your rights, we need to prevent others from denying you
33	+	these rights or asking you to surrender the rights. Therefore, you
34	+	have certain responsibilities if you distribute copies of the
35	+	software, or if you modify it: responsibilities to respect the freedom
36	+	of others.
37	+
38	+	For example, if you distribute copies of such a program, whether
39	+	gratis or for a fee, you must pass on to the recipients the same
40	+	freedoms that you received. You must make sure that they, too, receive
41	+	or can get the source code. And you must show them these terms so they
42	+	know their rights.
43	+
44	+	Developers that use the GNU GPL protect your rights with two steps:
45	+	(1) assert copyright on the software, and (2) offer you this License
46	+	giving you legal permission to copy, distribute and/or modify it.
47	+
48	+	For the developers' and authors' protection, the GPL clearly explains
49	+	that there is no warranty for this free software. For both users' and
50	+	authors' sake, the GPL requires that modified versions be marked as
51	+	changed, so that their problems will not be attributed erroneously to
52	+	authors of previous versions.
53	+
54	+	Some devices are designed to deny users access to install or run
55	+	modified versions of the software inside them, although the
56	+	manufacturer can do so. This is fundamentally incompatible with the
57	+	aim of protecting users' freedom to change the software. The
58	+	systematic pattern of such abuse occurs in the area of products for
59	+	individuals to use, which is precisely where it is most unacceptable.
60	+	Therefore, we have designed this version of the GPL to prohibit the
61	+	practice for those products. If such problems arise substantially in
62	+	other domains, we stand ready to extend this provision to those
63	+	domains in future versions of the GPL, as needed to protect the
64	+	freedom of users.
65	+
66	+	Finally, every program is threatened constantly by software patents.
67	+	States should not allow patents to restrict development and use of
68	+	software on general-purpose computers, but in those that do, we wish
69	+	to avoid the special danger that patents applied to a free program
70	+	could make it effectively proprietary. To prevent this, the GPL
71	+	assures that patents cannot be used to render the program non-free.
72	+
73	+	The precise terms and conditions for copying, distribution and
74	+	modification follow.
75	+
76	+	### TERMS AND CONDITIONS
77	+
78	+	#### 0. Definitions.
79	+
80	+	"This License" refers to version 3 of the GNU General Public License.
81	+
82	+	"Copyright" also means copyright-like laws that apply to other kinds
83	+	of works, such as semiconductor masks.
84	+
85	+	"The Program" refers to any copyrightable work licensed under this
86	+	License. Each licensee is addressed as "you". "Licensees" and
87	+	"recipients" may be individuals or organizations.
88	+
89	+	To "modify" a work means to copy from or adapt all or part of the work
90	+	in a fashion requiring copyright permission, other than the making of
91	+	an exact copy. The resulting work is called a "modified version" of
92	+	the earlier work or a work "based on" the earlier work.
93	+
94	+	A "covered work" means either the unmodified Program or a work based
95	+	on the Program.
96	+
97	+	To "propagate" a work means to do anything with it that, without
98	+	permission, would make you directly or secondarily liable for
99	+	infringement under applicable copyright law, except executing it on a
100	+	computer or modifying a private copy. Propagation includes copying,
101	+	distribution (with or without modification), making available to the
102	+	public, and in some countries other activities as well.
103	+
104	+	To "convey" a work means any kind of propagation that enables other
105	+	parties to make or receive copies. Mere interaction with a user
106	+	through a computer network, with no transfer of a copy, is not
107	+	conveying.
108	+
109	+	An interactive user interface displays "Appropriate Legal Notices" to
110	+	the extent that it includes a convenient and prominently visible
111	+	feature that (1) displays an appropriate copyright notice, and (2)
112	+	tells the user that there is no warranty for the work (except to the
113	+	extent that warranties are provided), that licensees may convey the
114	+	work under this License, and how to view a copy of this License. If
115	+	the interface presents a list of user commands or options, such as a
116	+	menu, a prominent item in the list meets this criterion.
117	+
118	+	#### 1. Source Code.
119	+
120	+	The "source code" for a work means the preferred form of the work for
121	+	making modifications to it. "Object code" means any non-source form of
122	+	a work.
123	+
124	+	A "Standard Interface" means an interface that either is an official
125	+	standard defined by a recognized standards body, or, in the case of
126	+	interfaces specified for a particular programming language, one that
127	+	is widely used among developers working in that language.
128	+
129	+	The "System Libraries" of an executable work include anything, other
130	+	than the work as a whole, that (a) is included in the normal form of
131	+	packaging a Major Component, but which is not part of that Major
132	+	Component, and (b) serves only to enable use of the work with that
133	+	Major Component, or to implement a Standard Interface for which an
134	+	implementation is available to the public in source code form. A
135	+	"Major Component", in this context, means a major essential component
136	+	(kernel, window system, and so on) of the specific operating system
137	+	(if any) on which the executable work runs, or a compiler used to
138	+	produce the work, or an object code interpreter used to run it.
139	+
140	+	The "Corresponding Source" for a work in object code form means all
141	+	the source code needed to generate, install, and (for an executable
142	+	work) run the object code and to modify the work, including scripts to
143	+	control those activities. However, it does not include the work's
144	+	System Libraries, or general-purpose tools or generally available free
145	+	programs which are used unmodified in performing those activities but
146	+	which are not part of the work. For example, Corresponding Source
147	+	includes interface definition files associated with source files for
148	+	the work, and the source code for shared libraries and dynamically
149	+	linked subprograms that the work is specifically designed to require,
150	+	such as by intimate data communication or control flow between those
151	+	subprograms and other parts of the work.
152	+
153	+	The Corresponding Source need not include anything that users can
154	+	regenerate automatically from other parts of the Corresponding Source.
155	+
156	+	The Corresponding Source for a work in source code form is that same
157	+	work.
158	+
159	+	#### 2. Basic Permissions.
160	+
161	+	All rights granted under this License are granted for the term of
162	+	copyright on the Program, and are irrevocable provided the stated
163	+	conditions are met. This License explicitly affirms your unlimited
164	+	permission to run the unmodified Program. The output from running a
165	+	covered work is covered by this License only if the output, given its
166	+	content, constitutes a covered work. This License acknowledges your
167	+	rights of fair use or other equivalent, as provided by copyright law.
168	+
169	+	You may make, run and propagate covered works that you do not convey,
170	+	without conditions so long as your license otherwise remains in force.
171	+	You may convey covered works to others for the sole purpose of having
172	+	them make modifications exclusively for you, or provide you with
173	+	facilities for running those works, provided that you comply with the
174	+	terms of this License in conveying all material for which you do not
175	+	control copyright. Those thus making or running the covered works for
176	+	you must do so exclusively on your behalf, under your direction and
177	+	control, on terms that prohibit them from making any copies of your
178	+	copyrighted material outside their relationship with you.
179	+
180	+	Conveying under any other circumstances is permitted solely under the
181	+	conditions stated below. Sublicensing is not allowed; section 10 makes
182	+	it unnecessary.
183	+
184	+	#### 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
185	+
186	+	No covered work shall be deemed part of an effective technological
187	+	measure under any applicable law fulfilling obligations under article
188	+	11 of the WIPO copyright treaty adopted on 20 December 1996, or
189	+	similar laws prohibiting or restricting circumvention of such
190	+	measures.
191	+
192	+	When you convey a covered work, you waive any legal power to forbid
193	+	circumvention of technological measures to the extent such
194	+	circumvention is effected by exercising rights under this License with
195	+	respect to the covered work, and you disclaim any intention to limit
196	+	operation or modification of the work as a means of enforcing, against
197	+	the work's users, your or third parties' legal rights to forbid
198	+	circumvention of technological measures.
199	+
200	+	#### 4. Conveying Verbatim Copies.
201	+
202	+	You may convey verbatim copies of the Program's source code as you
203	+	receive it, in any medium, provided that you conspicuously and
204	+	appropriately publish on each copy an appropriate copyright notice;
205	+	keep intact all notices stating that this License and any
206	+	non-permissive terms added in accord with section 7 apply to the code;
207	+	keep intact all notices of the absence of any warranty; and give all
208	+	recipients a copy of this License along with the Program.
209	+
210	+	You may charge any price or no price for each copy that you convey,
211	+	and you may offer support or warranty protection for a fee.
212	+
213	+	#### 5. Conveying Modified Source Versions.
214	+
215	+	You may convey a work based on the Program, or the modifications to
216	+	produce it from the Program, in the form of source code under the
217	+	terms of section 4, provided that you also meet all of these
218	+	conditions:
219	+
220	+	- a) The work must carry prominent notices stating that you modified
221	+	it, and giving a relevant date.
222	+	- b) The work must carry prominent notices stating that it is
223	+	released under this License and any conditions added under
224	+	section 7. This requirement modifies the requirement in section 4
225	+	to "keep intact all notices".
226	+	- c) You must license the entire work, as a whole, under this
227	+	License to anyone who comes into possession of a copy. This
228	+	License will therefore apply, along with any applicable section 7
229	+	additional terms, to the whole of the work, and all its parts,
230	+	regardless of how they are packaged. This License gives no
231	+	permission to license the work in any other way, but it does not
232	+	invalidate such permission if you have separately received it.
233	+	- d) If the work has interactive user interfaces, each must display
234	+	Appropriate Legal Notices; however, if the Program has interactive
235	+	interfaces that do not display Appropriate Legal Notices, your
236	+	work need not make them do so.
237	+
238	+	A compilation of a covered work with other separate and independent
239	+	works, which are not by their nature extensions of the covered work,
240	+	and which are not combined with it such as to form a larger program,
241	+	in or on a volume of a storage or distribution medium, is called an
242	+	"aggregate" if the compilation and its resulting copyright are not
243	+	used to limit the access or legal rights of the compilation's users
244	+	beyond what the individual works permit. Inclusion of a covered work
245	+	in an aggregate does not cause this License to apply to the other
246	+	parts of the aggregate.
247	+
248	+	#### 6. Conveying Non-Source Forms.
249	+
250	+	You may convey a covered work in object code form under the terms of
251	+	sections 4 and 5, provided that you also convey the machine-readable
252	+	Corresponding Source under the terms of this License, in one of these
253	+	ways:
254	+
255	+	- a) Convey the object code in, or embodied in, a physical product
256	+	(including a physical distribution medium), accompanied by the
257	+	Corresponding Source fixed on a durable physical medium
258	+	customarily used for software interchange.
259	+	- b) Convey the object code in, or embodied in, a physical product
260	+	(including a physical distribution medium), accompanied by a
261	+	written offer, valid for at least three years and valid for as
262	+	long as you offer spare parts or customer support for that product
263	+	model, to give anyone who possesses the object code either (1) a
264	+	copy of the Corresponding Source for all the software in the
265	+	product that is covered by this License, on a durable physical
266	+	medium customarily used for software interchange, for a price no
267	+	more than your reasonable cost of physically performing this
268	+	conveying of source, or (2) access to copy the Corresponding
269	+	Source from a network server at no charge.
270	+	- c) Convey individual copies of the object code with a copy of the
271	+	written offer to provide the Corresponding Source. This
272	+	alternative is allowed only occasionally and noncommercially, and
273	+	only if you received the object code with such an offer, in accord
274	+	with subsection 6b.
275	+	- d) Convey the object code by offering access from a designated
276	+	place (gratis or for a charge), and offer equivalent access to the
277	+	Corresponding Source in the same way through the same place at no
278	+	further charge. You need not require recipients to copy the
279	+	Corresponding Source along with the object code. If the place to
280	+	copy the object code is a network server, the Corresponding Source
281	+	may be on a different server (operated by you or a third party)
282	+	that supports equivalent copying facilities, provided you maintain
283	+	clear directions next to the object code saying where to find the
284	+	Corresponding Source. Regardless of what server hosts the
285	+	Corresponding Source, you remain obligated to ensure that it is
286	+	available for as long as needed to satisfy these requirements.
287	+	- e) Convey the object code using peer-to-peer transmission,
288	+	provided you inform other peers where the object code and
289	+	Corresponding Source of the work are being offered to the general
290	+	public at no charge under subsection 6d.
291	+
292	+	A separable portion of the object code, whose source code is excluded
293	+	from the Corresponding Source as a System Library, need not be
294	+	included in conveying the object code work.
295	+
296	+	A "User Product" is either (1) a "consumer product", which means any
297	+	tangible personal property which is normally used for personal,
298	+	family, or household purposes, or (2) anything designed or sold for
299	+	incorporation into a dwelling. In determining whether a product is a
300	+	consumer product, doubtful cases shall be resolved in favor of
301	+	coverage. For a particular product received by a particular user,
302	+	"normally used" refers to a typical or common use of that class of
303	+	product, regardless of the status of the particular user or of the way
304	+	in which the particular user actually uses, or expects or is expected
305	+	to use, the product. A product is a consumer product regardless of
306	+	whether the product has substantial commercial, industrial or
307	+	non-consumer uses, unless such uses represent the only significant
308	+	mode of use of the product.
309	+
310	+	"Installation Information" for a User Product means any methods,
311	+	procedures, authorization keys, or other information required to
312	+	install and execute modified versions of a covered work in that User
313	+	Product from a modified version of its Corresponding Source. The
314	+	information must suffice to ensure that the continued functioning of
315	+	the modified object code is in no case prevented or interfered with
316	+	solely because modification has been made.
317	+
318	+	If you convey an object code work under this section in, or with, or
319	+	specifically for use in, a User Product, and the conveying occurs as
320	+	part of a transaction in which the right of possession and use of the
321	+	User Product is transferred to the recipient in perpetuity or for a
322	+	fixed term (regardless of how the transaction is characterized), the
323	+	Corresponding Source conveyed under this section must be accompanied
324	+	by the Installation Information. But this requirement does not apply
325	+	if neither you nor any third party retains the ability to install
326	+	modified object code on the User Product (for example, the work has
327	+	been installed in ROM).
328	+
329	+	The requirement to provide Installation Information does not include a
330	+	requirement to continue to provide support service, warranty, or
331	+	updates for a work that has been modified or installed by the
332	+	recipient, or for the User Product in which it has been modified or
333	+	installed. Access to a network may be denied when the modification
334	+	itself materially and adversely affects the operation of the network
335	+	or violates the rules and protocols for communication across the
336	+	network.
337	+
338	+	Corresponding Source conveyed, and Installation Information provided,
339	+	in accord with this section must be in a format that is publicly
340	+	documented (and with an implementation available to the public in
341	+	source code form), and must require no special password or key for
342	+	unpacking, reading or copying.
343	+
344	+	#### 7. Additional Terms.
345	+
346	+	"Additional permissions" are terms that supplement the terms of this
347	+	License by making exceptions from one or more of its conditions.
348	+	Additional permissions that are applicable to the entire Program shall
349	+	be treated as though they were included in this License, to the extent
350	+	that they are valid under applicable law. If additional permissions
351	+	apply only to part of the Program, that part may be used separately
352	+	under those permissions, but the entire Program remains governed by
353	+	this License without regard to the additional permissions.
354	+
355	+	When you convey a copy of a covered work, you may at your option
356	+	remove any additional permissions from that copy, or from any part of
357	+	it. (Additional permissions may be written to require their own
358	+	removal in certain cases when you modify the work.) You may place
359	+	additional permissions on material, added by you to a covered work,
360	+	for which you have or can give appropriate copyright permission.
361	+
362	+	Notwithstanding any other provision of this License, for material you
363	+	add to a covered work, you may (if authorized by the copyright holders
364	+	of that material) supplement the terms of this License with terms:
365	+
366	+	- a) Disclaiming warranty or limiting liability differently from the
367	+	terms of sections 15 and 16 of this License; or
368	+	- b) Requiring preservation of specified reasonable legal notices or
369	+	author attributions in that material or in the Appropriate Legal
370	+	Notices displayed by works containing it; or
371	+	- c) Prohibiting misrepresentation of the origin of that material,
372	+	or requiring that modified versions of such material be marked in
373	+	reasonable ways as different from the original version; or
374	+	- d) Limiting the use for publicity purposes of names of licensors
375	+	or authors of the material; or
376	+	- e) Declining to grant rights under trademark law for use of some
377	+	trade names, trademarks, or service marks; or
378	+	- f) Requiring indemnification of licensors and authors of that
379	+	material by anyone who conveys the material (or modified versions
380	+	of it) with contractual assumptions of liability to the recipient,
381	+	for any liability that these contractual assumptions directly
382	+	impose on those licensors and authors.
383	+
384	+	All other non-permissive additional terms are considered "further
385	+	restrictions" within the meaning of section 10. If the Program as you
386	+	received it, or any part of it, contains a notice stating that it is
387	+	governed by this License along with a term that is a further
388	+	restriction, you may remove that term. If a license document contains
389	+	a further restriction but permits relicensing or conveying under this
390	+	License, you may add to a covered work material governed by the terms
391	+	of that license document, provided that the further restriction does
392	+	not survive such relicensing or conveying.
393	+
394	+	If you add terms to a covered work in accord with this section, you
395	+	must place, in the relevant source files, a statement of the
396	+	additional terms that apply to those files, or a notice indicating
397	+	where to find the applicable terms.
398	+
399	+	Additional terms, permissive or non-permissive, may be stated in the
400	+	form of a separately written license, or stated as exceptions; the
401	+	above requirements apply either way.
402	+
403	+	#### 8. Termination.
404	+
405	+	You may not propagate or modify a covered work except as expressly
406	+	provided under this License. Any attempt otherwise to propagate or
407	+	modify it is void, and will automatically terminate your rights under
408	+	this License (including any patent licenses granted under the third
409	+	paragraph of section 11).
410	+
411	+	However, if you cease all violation of this License, then your license
412	+	from a particular copyright holder is reinstated (a) provisionally,
413	+	unless and until the copyright holder explicitly and finally
414	+	terminates your license, and (b) permanently, if the copyright holder
415	+	fails to notify you of the violation by some reasonable means prior to
416	+	60 days after the cessation.
417	+
418	+	Moreover, your license from a particular copyright holder is
419	+	reinstated permanently if the copyright holder notifies you of the
420	+	violation by some reasonable means, this is the first time you have
421	+	received notice of violation of this License (for any work) from that
422	+	copyright holder, and you cure the violation prior to 30 days after
423	+	your receipt of the notice.
424	+
425	+	Termination of your rights under this section does not terminate the
426	+	licenses of parties who have received copies or rights from you under
427	+	this License. If your rights have been terminated and not permanently
428	+	reinstated, you do not qualify to receive new licenses for the same
429	+	material under section 10.
430	+
431	+	#### 9. Acceptance Not Required for Having Copies.
432	+
433	+	You are not required to accept this License in order to receive or run
434	+	a copy of the Program. Ancillary propagation of a covered work
435	+	occurring solely as a consequence of using peer-to-peer transmission
436	+	to receive a copy likewise does not require acceptance. However,
437	+	nothing other than this License grants you permission to propagate or
438	+	modify any covered work. These actions infringe copyright if you do
439	+	not accept this License. Therefore, by modifying or propagating a
440	+	covered work, you indicate your acceptance of this License to do so.
441	+
442	+	#### 10. Automatic Licensing of Downstream Recipients.
443	+
444	+	Each time you convey a covered work, the recipient automatically
445	+	receives a license from the original licensors, to run, modify and
446	+	propagate that work, subject to this License. You are not responsible
447	+	for enforcing compliance by third parties with this License.
448	+
449	+	An "entity transaction" is a transaction transferring control of an
450	+	organization, or substantially all assets of one, or subdividing an
451	+	organization, or merging organizations. If propagation of a covered
452	+	work results from an entity transaction, each party to that
453	+	transaction who receives a copy of the work also receives whatever
454	+	licenses to the work the party's predecessor in interest had or could
455	+	give under the previous paragraph, plus a right to possession of the
456	+	Corresponding Source of the work from the predecessor in interest, if
457	+	the predecessor has it or can get it with reasonable efforts.
458	+
459	+	You may not impose any further restrictions on the exercise of the
460	+	rights granted or affirmed under this License. For example, you may
461	+	not impose a license fee, royalty, or other charge for exercise of
462	+	rights granted under this License, and you may not initiate litigation
463	+	(including a cross-claim or counterclaim in a lawsuit) alleging that
464	+	any patent claim is infringed by making, using, selling, offering for
465	+	sale, or importing the Program or any portion of it.
466	+
467	+	#### 11. Patents.
468	+
469	+	A "contributor" is a copyright holder who authorizes use under this
470	+	License of the Program or a work on which the Program is based. The
471	+	work thus licensed is called the contributor's "contributor version".
472	+
473	+	A contributor's "essential patent claims" are all patent claims owned
474	+	or controlled by the contributor, whether already acquired or
475	+	hereafter acquired, that would be infringed by some manner, permitted
476	+	by this License, of making, using, or selling its contributor version,
477	+	but do not include claims that would be infringed only as a
478	+	consequence of further modification of the contributor version. For
479	+	purposes of this definition, "control" includes the right to grant
480	+	patent sublicenses in a manner consistent with the requirements of
481	+	this License.
482	+
483	+	Each contributor grants you a non-exclusive, worldwide, royalty-free
484	+	patent license under the contributor's essential patent claims, to
485	+	make, use, sell, offer for sale, import and otherwise run, modify and
486	+	propagate the contents of its contributor version.
487	+
488	+	In the following three paragraphs, a "patent license" is any express
489	+	agreement or commitment, however denominated, not to enforce a patent
490	+	(such as an express permission to practice a patent or covenant not to
491	+	sue for patent infringement). To "grant" such a patent license to a
492	+	party means to make such an agreement or commitment not to enforce a
493	+	patent against the party.
494	+
495	+	If you convey a covered work, knowingly relying on a patent license,
496	+	and the Corresponding Source of the work is not available for anyone
497	+	to copy, free of charge and under the terms of this License, through a
498	+	publicly available network server or other readily accessible means,
499	+	then you must either (1) cause the Corresponding Source to be so
500	+	available, or (2) arrange to deprive yourself of the benefit of the
501	+	patent license for this particular work, or (3) arrange, in a manner
502	+	consistent with the requirements of this License, to extend the patent
503	+	license to downstream recipients. "Knowingly relying" means you have
504	+	actual knowledge that, but for the patent license, your conveying the
505	+	covered work in a country, or your recipient's use of the covered work
506	+	in a country, would infringe one or more identifiable patents in that
507	+	country that you have reason to believe are valid.
508	+
509	+	If, pursuant to or in connection with a single transaction or
510	+	arrangement, you convey, or propagate by procuring conveyance of, a
511	+	covered work, and grant a patent license to some of the parties
512	+	receiving the covered work authorizing them to use, propagate, modify
513	+	or convey a specific copy of the covered work, then the patent license
514	+	you grant is automatically extended to all recipients of the covered
515	+	work and works based on it.
516	+
517	+	A patent license is "discriminatory" if it does not include within the
518	+	scope of its coverage, prohibits the exercise of, or is conditioned on
519	+	the non-exercise of one or more of the rights that are specifically
520	+	granted under this License. You may not convey a covered work if you
521	+	are a party to an arrangement with a third party that is in the
522	+	business of distributing software, under which you make payment to the
523	+	third party based on the extent of your activity of conveying the
524	+	work, and under which the third party grants, to any of the parties
525	+	who would receive the covered work from you, a discriminatory patent
526	+	license (a) in connection with copies of the covered work conveyed by
527	+	you (or copies made from those copies), or (b) primarily for and in
528	+	connection with specific products or compilations that contain the
529	+	covered work, unless you entered into that arrangement, or that patent
530	+	license was granted, prior to 28 March 2007.
531	+
532	+	Nothing in this License shall be construed as excluding or limiting
533	+	any implied license or other defenses to infringement that may
534	+	otherwise be available to you under applicable patent law.
535	+
536	+	#### 12. No Surrender of Others' Freedom.
537	+
538	+	If conditions are imposed on you (whether by court order, agreement or
539	+	otherwise) that contradict the conditions of this License, they do not
540	+	excuse you from the conditions of this License. If you cannot convey a
541	+	covered work so as to satisfy simultaneously your obligations under
542	+	this License and any other pertinent obligations, then as a
543	+	consequence you may not convey it at all. For example, if you agree to
544	+	terms that obligate you to collect a royalty for further conveying
545	+	from those to whom you convey the Program, the only way you could
546	+	satisfy both those terms and this License would be to refrain entirely
547	+	from conveying the Program.
548	+
549	+	#### 13. Use with the GNU Affero General Public License.
550	+
551	+	Notwithstanding any other provision of this License, you have
552	+	permission to link or combine any covered work with a work licensed
553	+	under version 3 of the GNU Affero General Public License into a single
554	+	combined work, and to convey the resulting work. The terms of this
555	+	License will continue to apply to the part which is the covered work,
556	+	but the special requirements of the GNU Affero General Public License,
557	+	section 13, concerning interaction through a network will apply to the
558	+	combination as such.
559	+
560	+	#### 14. Revised Versions of this License.
561	+
562	+	The Free Software Foundation may publish revised and/or new versions
563	+	of the GNU General Public License from time to time. Such new versions
564	+	will be similar in spirit to the present version, but may differ in
565	+	detail to address new problems or concerns.
566	+
567	+	Each version is given a distinguishing version number. If the Program
568	+	specifies that a certain numbered version of the GNU General Public
569	+	License "or any later version" applies to it, you have the option of
570	+	following the terms and conditions either of that numbered version or
571	+	of any later version published by the Free Software Foundation. If the
572	+	Program does not specify a version number of the GNU General Public
573	+	License, you may choose any version ever published by the Free
574	+	Software Foundation.
575	+
576	+	If the Program specifies that a proxy can decide which future versions
577	+	of the GNU General Public License can be used, that proxy's public
578	+	statement of acceptance of a version permanently authorizes you to
579	+	choose that version for the Program.
580	+
581	+	Later license versions may give you additional or different
582	+	permissions. However, no additional obligations are imposed on any
583	+	author or copyright holder as a result of your choosing to follow a
584	+	later version.
585	+
586	+	#### 15. Disclaimer of Warranty.
587	+
588	+	THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
589	+	APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
590	+	HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
591	+	WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
592	+	LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
593	+	A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
594	+	PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
595	+	DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
596	+	CORRECTION.
597	+
598	+	#### 16. Limitation of Liability.
599	+
600	+	IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
601	+	WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
602	+	CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
603	+	INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
604	+	ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
605	+	NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
606	+	LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
607	+	TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
608	+	PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
609	+
610	+	#### 17. Interpretation of Sections 15 and 16.
611	+
612	+	If the disclaimer of warranty and limitation of liability provided
613	+	above cannot be given local legal effect according to their terms,
614	+	reviewing courts shall apply local law that most closely approximates
615	+	an absolute waiver of all civil liability in connection with the
616	+	Program, unless a warranty or assumption of liability accompanies a
617	+	copy of the Program in return for a fee.
618	+
619	+	END OF TERMS AND CONDITIONS
620	+
621	+	### How to Apply These Terms to Your New Programs
622	+
623	+	If you develop a new program, and you want it to be of the greatest
624	+	possible use to the public, the best way to achieve this is to make it
625	+	free software which everyone can redistribute and change under these
626	+	terms.
627	+
628	+	To do so, attach the following notices to the program. It is safest to
629	+	attach them to the start of each source file to most effectively state
630	+	the exclusion of warranty; and each file should have at least the
631	+	"copyright" line and a pointer to where the full notice is found.
632	+
633	+	<one line to give the program's name and a brief idea of what it does.>
634	+	Copyright (C) <year> <name of author>
635	+
636	+	This program is free software: you can redistribute it and/or modify
637	+	it under the terms of the GNU General Public License as published by
638	+	the Free Software Foundation, either version 3 of the License, or
639	+	(at your option) any later version.
640	+
641	+	This program is distributed in the hope that it will be useful,
642	+	but WITHOUT ANY WARRANTY; without even the implied warranty of
643	+	MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
644	+	GNU General Public License for more details.
645	+
646	+	You should have received a copy of the GNU General Public License
647	+	along with this program. If not, see <https://www.gnu.org/licenses/>.
648	+
649	+	Also add information on how to contact you by electronic and paper
650	+	mail.
651	+
652	+	If the program does terminal interaction, make it output a short
653	+	notice like this when it starts in an interactive mode:
654	+
655	+	<program> Copyright (C) <year> <name of author>
656	+	This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
657	+	This is free software, and you are welcome to redistribute it
658	+	under certain conditions; type `show c' for details.
659	+
660	+	The hypothetical commands \`show w' and \`show c' should show the
661	+	appropriate parts of the General Public License. Of course, your
662	+	program's commands might be different; for a GUI interface, you would
663	+	use an "about box".
664	+
665	+	You should also get your employer (if you work as a programmer) or
666	+	school, if any, to sign a "copyright disclaimer" for the program, if
667	+	necessary. For more information on this, and how to apply and follow
668	+	the GNU GPL, see <https://www.gnu.org/licenses/>.
669	+
670	+	The GNU General Public License does not permit incorporating your
671	+	program into proprietary programs. If your program is a subroutine
672	+	library, you may consider it more useful to permit linking proprietary
673	+	applications with the library. If this is what you want to do, use the
674	+	GNU Lesser General Public License instead of this License. But first,
675	+	please read <https://www.gnu.org/licenses/why-not-lgpl.html>.

1	+	Text4Shell scanner for Burp Suite
2	+	================================
3	+
4	+	Note about detection capabilities: this plugin will only supply the built-in
5	+	active scanner with payloads, thus for optimal coverage vs. performance, you'll
6	+	have to configure your scan properly – just as with any other built-in or
7	+	extension-provided scan.
8	+
9	+	Single-issue scan
10	+	-----------------
11	+
12	+	If you'd like to scan only for CVE-2022-42889 (and not other things such as
13	+	XSS or SQLi), this plugin makes it possible.
14	+
15	+	By following the instructions below, the scanner will only
16	+	perform Text4Shell checks on all insertion points if the scan configuration
17	+	created as a result is used.
18	+
19	+	1. When creating a new scan, click `Select from library` on the `Scan configuration` tab
20	+	2. Pick `Audit checks - extensions only` which is built into Burp Suite Pro 2.x
21	+	3. Disable every other extension (if applicable) that have an active scan check registered (such as ActiveScan++, Backslash powered scanning, Burp Bounty, etc.) so that only the Text4Shell scanner runs
22	+
23	+	Building
24	+	--------
25	+
26	+	Execute `./gradlew build` and you'll have the plugin ready in
27	+	`build/libs/burp-text4shell.jar`
28	+
29	+	License
30	+	-------
31	+
32	+	The whole project is available under the GNU General Public License v3.0,
33	+	see `LICENSE.md`.
