	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>.

	1	# PHP-Blog
	2
	3	PHP-Blog is a simple, database-free blogging web app written in PHP, with the
	4	support of Markdown and JSON.
	5
	6	## Philosophy
	7
	8	Websites, blogs included, should be able to
	9	[degrade gracefully over time](https://brandur.org/fragments/graceful-degradation-time).
	10	For blogs, this means open-sourcing your blog and publishing articles and
	11	metadata straight to the Git repository.
	12
	13	This project allows you to blog and keep your articles, article metadata, and
	14	user comments within this repo. This is done through the use of JSON files to
	15	store article metadata and user comments (instead of using a database), and the
	16	use of Markdown files to store written articles.
	17
	18	## Installation
	19
	20	Steps:
	21
	22	```bash
	23	cd yourBlog.com
	24	```
	25
	26	```bash
	27	git clone <REPO_URL>
	28	```
	29
	30	Change the global variables at the top of the `index.php` script:
	31
	32	```php
	33	$websiteProtocol = 'https://';
	34	$shortDomain = 'yourBlog.com';
	35	```
	36
	37	Remove my personal data files:
	38
	39	```bash
	40	cd _data/ && rm -rf *
	41	```
	42
	43	Add blank data files:
	44
	45	```bash
	46	touch comments.json && touch metadata.json
	47	```
	48
	49	Remove my personal posts:
	50
	51	```bash
	52	cd ../posts/ && rm -rf *
	53	```
	54
	55	Add your first post:
	56
	57	```bash
	58	touch 001-your-first-post.md
	59	```
	60
	61	For every post you add, also add the applicable JSON object in
	62	`_data/metadata.json`.
	63
	64	Finally, enable `FallbackResource` in your Apache `.conf` file or in your
	65	`.htaccess` file:
	66
	67	```apacheconf
	68	FallbackResource /index.php
	69	```

	112
	113	### File: `index.php`
	114
	115	This file is the FallbackResource for the entire directory, so non-existent
	116	folders/files requested by users will be sent to `index.php` for processing.
	117	This file uses a switch statement to read the request URL and direct the user to
	118	various functions.
	119
	120	Each function in this file will call various other functions/classes and then
	121	send the output to the template file.
	122
	123	---
	124
	125	### Folder: `_classes`
	126
	127	#### File: `Comment.php`
	128
	129	This class allows for the creation of user comments and provides the
	130	`saveComment()` function to do so.
	131
	132	#### File: `Parsedown.php`
	133
	134	This class was not created by me, it comes from
	135	[erusev/parsedown](https://github.com/erusev/parsedown). See his
	136	[MIT License](https://raw.githubusercontent.com/erusev/parsedown/master/LICENSE.txt)
	137	for licensing questions on this code.
	138
	139	This class provides numerous capabilities to parse Markdown files and variables
	140	to HTML.
	141
	142	#### File: `Template.php`
	143
	144	This class allows for the creation of a final HTML page to show the user. The
	145	`echoTemplate()` function will replace the `{}` templates in the
	146	`_templates/template.html` file.
	147
	148	---
	149
	150	### Folder: `_data`
	151
	152	#### File: `metadata.json`
	153
	154	Your `metadata.json` file will need to contain an object for each post in the
	155	`post` folder. If you don't add an object for your new blog post, it won't be
	156	displayed in the browser. The structure will follow this exactly:
	157
	158	```
	159	{
	160	"id": "001",
	161	"title": "Title of Post",
	162	"author": "Your Name",
	163	"description": "A quick little description for SEO and RSS.",
	164	"tag": "my-category",
	165	"created": "2018-12-08 00:00:00",
	166	"modified": "2018-12-08 00:00:00",
	167	"link": "https:\/\/www.example.com\/post\/blog-post-name.html",
	168	"published": "Yes"
	169	}
	170	```
	171
	172	#### File: `comments.json`
	173
	174	This file is updated server-side as users submit comments on posts. You can
	175	commit these changes back to your repository by making sure the server-side git
	176	repo can read & write. Then just create git commits back to your repo from there
	177	(you can even create periodic cron jobs to do this for you, if you trust it).
	178
	179	You will need to perform the following commands to ensure whatever 'user' is
	180	writing to the `comments.json` file has the proper permissions. For Apache, the
	181	user is probably `www-data`.
	182
	183	```bash
	184	chgrp -R www-data /path/to/website/
	185	chmod -R g+w _data/comments.json
	186	```
	187
	188	---
	189
	190	### Folder: `_functions`
	191
	192	#### File: `loadJSON.php`
	193
	194	This file contains four (4) functions that can be called to load JSON data from
	195	a local file in various ways.
	196
	197	#### File: `loadRSS.php`
	198
	199	This file contains a single function that will grab the `_data/metadata.json`
	200	file and generate a complete RSS file.
	201
	202	#### File: `parseMarkdown.php`
	203
	204	This file uses the `Parsedown` class to parse a posts or comments from Markdown
	205	to HTML. It also adds additional attributes to any link found in the Markdown.
	206
	207	#### File: `submitComment.php`
	208
	209	This file uses the `Comment` class to create a comment and then save it to
	210	`_data/comments.json`.
	211
	212	---
	213
	214	### Folder: `_templates`
	215
	216	#### File: `template.html`
	217
	218	This file is the end result template that will be shown to users, regardless of
	219	the URL they enter. The main content in the `<body>` and various elements in the
	220	`<head>` will change depending which function calls this template.
	221
	222	---
	223
	224	### Folder: `posts`
	225
	226	Your `posts` folder will contain the `.md` files that will comprise the body of
	227	your blog post. Formatting follows standard Markdown guidelines.
	228
	229	---
	230
	231	### Folder: `static`
	232
	233	This folder contains the main CSS file (`app.css`), as well as a pair of
	234	optional static files from [PrismJS](https://prismjs.com) to enable syntax
	235	highlighting in any code blocks found in posts or comments.
	236
	237	To remove the optional files, simply delete the unwanted files and remove the
	238	following from the `pageExtras` parameter string in the `ShowComments()` and
	239	`ShowPost()` functions in `index.php`:
	240
	241	```html
	242	<link rel="stylesheet" href="/static/prism.css" />
	243	<script src="/static/prism.js"></script>
