LICENSE

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

README.md

1	+	# Zygisk-based reFlutter implementation
2	+
3	+	reFlutter is a handy tool for reverse engineering Flutter-based applications for both rooted and non-rooted Android. To use Reflutter, you must obtain your APK and replace libflutter.so, resign the APK and reinstall it.
4	+
5	+	The Zygisk module is designed to empower rooted Android users by simplifying the process. With the provided app, you can easily download `libflutter.so` from reFlutter project. The Zygisk module will then seamlessly replace `libflutter.so` at runtime, making the process straightforward and efficient.
6	+
7	+	Please note: set up your Proxy IP. Set your Burp Suite like you would set when using reFlutter (listen to `*:8083` and enable "Support invisible proxying").
8	+
9	+	## Requirements
10	+
11	+	Rooted Android with Magisk installed and Zygisk Enabled
12	+
13	+	## Installation
14	+
15	+	Download the ZIP file, and install it as Zygisk module. You can also do it from ADB:
16	+
17	+
18	+	```
19	+	adb push zygiskreflutter_1.0.zip /sdcard/
20	+	adb shell su -c magisk --install-module /sdcard/zygiskreflutter_1.0.zip
21	+	adb reboot
22	+	```
23	+
24	+
25	+	Install the APK, then setup your proxy IP from "Set Proxy Host" menu.
26	+
27	+	Select the app that you want to reFlutter, click download library, once it is downloaded, you can enable the proxy feature.
28	+
29	+	You can now start the target app normally
30	+
31	+
32	+	Check adb log and filter it by "ZygiskReflutter" in case you found a problem
33	+

26	+	***************
27	+	* Introduction
28	+	***************
29	+
30	+	On Android, all app processes are forked from a special daemon called "Zygote".
31	+	For each new app process, zygote will fork a new process and perform "specialization".
32	+	This specialization operation enforces the Android security sandbox on the newly forked
33	+	process to make sure that 3rd party application code is only loaded after it is being
34	+	restricted within a sandbox.
35	+
36	+	On Android, there is also this special process called "system_server". This single
37	+	process hosts a significant portion of system services, which controls how the
38	+	Android operating system and apps interact with each other.
39	+
40	+	The Zygisk framework provides a way to allow developers to build modules and run custom
41	+	code before and after system_server and any app processes' specialization.
42	+	This enable developers to inject code and alter the behavior of system_server and app processes.
43	+
44	+	Please note that modules will only be loaded after zygote has forked the child process.
45	+	THIS MEANS ALL OF YOUR CODE RUNS IN THE APP/SYSTEM_SERVER PROCESS, NOT THE ZYGOTE DAEMON!
46	+
47	+	*********************
48	+	* Development Guide
49	+	*********************
50	+
51	+	Define a class and inherit zygisk::ModuleBase to implement the functionality of your module.
52	+	Use the macro REGISTER_ZYGISK_MODULE(className) to register that class to Zygisk.
53	+
54	+	Example code:
55	+
56	+	static jint (orig_logger_entry_max)(JNIEnv env);
57	+	static jint my_logger_entry_max(JNIEnv *env) { return orig_logger_entry_max(env); }
58	+
59	+	class ExampleModule : public zygisk::ModuleBase {
60	+	public:
61	+	void onLoad(zygisk::Api api, JNIEnv env) override {
62	+	this->api = api;
63	+	this->env = env;
64	+	}
65	+	void preAppSpecialize(zygisk::AppSpecializeArgs *args) override {
66	+	JNINativeMethod methods[] = {
67	+	{ "logger_entry_max_payload_native", "()I", (void*) my_logger_entry_max },
68	+	};
69	+	api->hookJniNativeMethods(env, "android/util/Log", methods, 1);
70	+	(void *) &orig_logger_entry_max = methods[0].fnPtr;
71	+	}
72	+	private:
73	+	zygisk::Api *api;
74	+	JNIEnv *env;
75	+	};
76	+
77	+	REGISTER_ZYGISK_MODULE(ExampleModule)
78	+
79	+	-----------------------------------------------------------------------------------------
80	+
81	+	Since your module class's code runs with either Zygote's privilege in pre[XXX]Specialize,
82	+	or runs in the sandbox of the target process in post[XXX]Specialize, the code in your class
83	+	never runs in a true superuser environment.
84	+
85	+	If your module require access to superuser permissions, you can create and register
86	+	a root companion handler function. This function runs in a separate root companion
87	+	daemon process, and an Unix domain socket is provided to allow you to perform IPC between
88	+	your target process and the root companion process.
89	+
90	+	Example code:
91	+
92	+	static void example_handler(int socket) { ... }
93	+
94	+	REGISTER_ZYGISK_COMPANION(example_handler)
