"General Public License, version 3"
© Paul Boersma 2021

This is the license under which Praat as a whole is distributed.
`
						GNU GENERAL PUBLIC LICENSE
						   Version 3, 29 June 2007

	 Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
	 Everyone is permitted to copy and distribute verbatim copies
	 of this license document, but changing it is not allowed.

								Preamble

	  The GNU General Public License is a free, copyleft license for
	software and other kinds of works.

	  The licenses for most software and other practical works are designed
	to take away your freedom to share and change the works.  By contrast,
	the GNU General Public License is intended to guarantee your freedom to
	share and change all versions of a program--to make sure it remains free
	software for all its users.  We, the Free Software Foundation, use the
	GNU General Public License for most of our software; it applies also to
	any other work released this way by its authors.  You can apply it to
	your programs, too.

	  When we speak of free software, we are referring to freedom, not
	price.  Our General Public Licenses are designed to make sure that you
	have the freedom to distribute copies of free software (and charge for
	them if you wish), that you receive source code or can get it if you
	want it, that you can change the software or use pieces of it in new
	free programs, and that you know you can do these things.

	  To protect your rights, we need to prevent others from denying you
	these rights or asking you to surrender the rights.  Therefore, you have
	certain responsibilities if you distribute copies of the software, or if
	you modify it: responsibilities to respect the freedom of others.

	  For example, if you distribute copies of such a program, whether
	gratis or for a fee, you must pass on to the recipients the same
	freedoms that you received.  You must make sure that they, too, receive
	or can get the source code.  And you must show them these terms so they
	know their rights.

	  Developers that use the GNU GPL protect your rights with two steps:
	(1) assert copyright on the software, and (2) offer you this License
	giving you legal permission to copy, distribute and/or modify it.

	  For the developers' and authors' protection, the GPL clearly explains
	that there is no warranty for this free software.  For both users' and
	authors' sake, the GPL requires that modified versions be marked as
	changed, so that their problems will not be attributed erroneously to
	authors of previous versions.

	  Some devices are designed to deny users access to install or run
	modified versions of the software inside them, although the manufacturer
	can do so.  This is fundamentally incompatible with the aim of
	protecting users' freedom to change the software.  The systematic
	pattern of such abuse occurs in the area of products for individuals to
	use, which is precisely where it is most unacceptable.  Therefore, we
	have designed this version of the GPL to prohibit the practice for those
	products.  If such problems arise substantially in other domains, we
	stand ready to extend this provision to those domains in future versions
	of the GPL, as needed to protect the freedom of users.

	  Finally, every program is threatened constantly by software patents.
	States should not allow patents to restrict development and use of
	software on general-purpose computers, but in those that do, we wish to
	avoid the special danger that patents applied to a free program could
	make it effectively proprietary.  To prevent this, the GPL assures that
	patents cannot be used to render the program non-free.

	  The precise terms and conditions for copying, distribution and
	modification follow.

						   TERMS AND CONDITIONS

	  0. Definitions.

	  "This License" refers to version 3 of the GNU General Public License.

	  "Copyright" also means copyright-like laws that apply to other kinds of
	works, such as semiconductor masks.

	  "The Program" refers to any copyrightable work licensed under this
	License.  Each licensee is addressed as "you".  "Licensees" and
	"recipients" may be individuals or organizations.

	  To "modify" a work means to copy from or adapt all or part of the work
	in a fashion requiring copyright permission, other than the making of an
	exact copy.  The resulting work is called a "modified version" of the
	earlier work or a work "based on" the earlier work.

	  A "covered work" means either the unmodified Program or a work based
	on the Program.

	  To "propagate" a work means to do anything with it that, without
	permission, would make you directly or secondarily liable for
	infringement under applicable copyright law, except executing it on a
	computer or modifying a private copy.  Propagation includes copying,
	distribution (with or without modification), making available to the
	public, and in some countries other activities as well.

	  To "convey" a work means any kind of propagation that enables other
	parties to make or receive copies.  Mere interaction with a user through
	a computer network, with no transfer of a copy, is not conveying.

	  An interactive user interface displays "Appropriate Legal Notices"
	to the extent that it includes a convenient and prominently visible
	feature that (1) displays an appropriate copyright notice, and (2)
	tells the user that there is no warranty for the work (except to the
	extent that warranties are provided), that licensees may convey the
	work under this License, and how to view a copy of this License.  If
	the interface presents a list of user commands or options, such as a
	menu, a prominent item in the list meets this criterion.

	  1. Source Code.

	  The "source code" for a work means the preferred form of the work
	for making modifications to it.  "Object code" means any non-source
	form of a work.

	  A "Standard Interface" means an interface that either is an official
	standard defined by a recognized standards body, or, in the case of
	interfaces specified for a particular programming language, one that
	is widely used among developers working in that language.

	  The "System Libraries" of an executable work include anything, other
	than the work as a whole, that (a) is included in the normal form of
	packaging a Major Component, but which is not part of that Major
	Component, and (b) serves only to enable use of the work with that
	Major Component, or to implement a Standard Interface for which an
	implementation is available to the public in source code form.  A
	"Major Component", in this context, means a major essential component
	(kernel, window system, and so on) of the specific operating system
	(if any) on which the executable work runs, or a compiler used to
	produce the work, or an object code interpreter used to run it.

	  The "Corresponding Source" for a work in object code form means all
	the source code needed to generate, install, and (for an executable
	work) run the object code and to modify the work, including scripts to
	control those activities.  However, it does not include the work's
	System Libraries, or general-purpose tools or generally available free
	programs which are used unmodified in performing those activities but
	which are not part of the work.  For example, Corresponding Source
	includes interface definition files associated with source files for
	the work, and the source code for shared libraries and dynamically
	linked subprograms that the work is specifically designed to require,
	such as by intimate data communication or control flow between those
	subprograms and other parts of the work.

	  The Corresponding Source need not include anything that users
	can regenerate automatically from other parts of the Corresponding
	Source.

	  The Corresponding Source for a work in source code form is that
	same work.

	  2. Basic Permissions.

	  All rights granted under this License are granted for the term of
	copyright on the Program, and are irrevocable provided the stated
	conditions are met.  This License explicitly affirms your unlimited
	permission to run the unmodified Program.  The output from running a
	covered work is covered by this License only if the output, given its
	content, constitutes a covered work.  This License acknowledges your
	rights of fair use or other equivalent, as provided by copyright law.

	  You may make, run and propagate covered works that you do not
	convey, without conditions so long as your license otherwise remains
	in force.  You may convey covered works to others for the sole purpose
	of having them make modifications exclusively for you, or provide you
	with facilities for running those works, provided that you comply with
	the terms of this License in conveying all material for which you do
	not control copyright.  Those thus making or running the covered works
	for you must do so exclusively on your behalf, under your direction
	and control, on terms that prohibit them from making any copies of
	your copyrighted material outside their relationship with you.

	  Conveying under any other circumstances is permitted solely under
	the conditions stated below.  Sublicensing is not allowed; section 10
	makes it unnecessary.

	  3. Protecting Users' Legal Rights From Anti-Circumvention Law.

	  No covered work shall be deemed part of an effective technological
	measure under any applicable law fulfilling obligations under article
	11 of the WIPO copyright treaty adopted on 20 December 1996, or
	similar laws prohibiting or restricting circumvention of such
	measures.

	  When you convey a covered work, you waive any legal power to forbid
	circumvention of technological measures to the extent such circumvention
	is effected by exercising rights under this License with respect to
	the covered work, and you disclaim any intention to limit operation or
	modification of the work as a means of enforcing, against the work's
	users, your or third parties' legal rights to forbid circumvention of
	technological measures.

	  4. Conveying Verbatim Copies.

	  You may convey verbatim copies of the Program's source code as you
	receive it, in any medium, provided that you conspicuously and
	appropriately publish on each copy an appropriate copyright notice;
	keep intact all notices stating that this License and any
	non-permissive terms added in accord with section 7 apply to the code;
	keep intact all notices of the absence of any warranty; and give all
	recipients a copy of this License along with the Program.

	  You may charge any price or no price for each copy that you convey,
	and you may offer support or warranty protection for a fee.

	  5. Conveying Modified Source Versions.

	  You may convey a work based on the Program, or the modifications to
	produce it from the Program, in the form of source code under the
	terms of section 4, provided that you also meet all of these conditions:

		a) The work must carry prominent notices stating that you modified
		it, and giving a relevant date.

		b) The work must carry prominent notices stating that it is
		released under this License and any conditions added under section
		7.  This requirement modifies the requirement in section 4 to
		"keep intact all notices".

		c) You must license the entire work, as a whole, under this
		License to anyone who comes into possession of a copy.  This
		License will therefore apply, along with any applicable section 7
		additional terms, to the whole of the work, and all its parts,
		regardless of how they are packaged.  This License gives no
		permission to license the work in any other way, but it does not
		invalidate such permission if you have separately received it.

		d) If the work has interactive user interfaces, each must display
		Appropriate Legal Notices; however, if the Program has interactive
		interfaces that do not display Appropriate Legal Notices, your
		work need not make them do so.

	  A compilation of a covered work with other separate and independent
	works, which are not by their nature extensions of the covered work,
	and which are not combined with it such as to form a larger program,
	in or on a volume of a storage or distribution medium, is called an
	"aggregate" if the compilation and its resulting copyright are not
	used to limit the access or legal rights of the compilation's users
	beyond what the individual works permit.  Inclusion of a covered work
	in an aggregate does not cause this License to apply to the other
	parts of the aggregate.

	  6. Conveying Non-Source Forms.

	  You may convey a covered work in object code form under the terms
	of sections 4 and 5, provided that you also convey the
	machine-readable Corresponding Source under the terms of this License,
	in one of these ways:

		a) Convey the object code in, or embodied in, a physical product
		(including a physical distribution medium), accompanied by the
		Corresponding Source fixed on a durable physical medium
		customarily used for software interchange.

		b) Convey the object code in, or embodied in, a physical product
		(including a physical distribution medium), accompanied by a
		written offer, valid for at least three years and valid for as
		long as you offer spare parts or customer support for that product
		model, to give anyone who possesses the object code either (1) a
		copy of the Corresponding Source for all the software in the
		product that is covered by this License, on a durable physical
		medium customarily used for software interchange, for a price no
		more than your reasonable cost of physically performing this
		conveying of source, or (2) access to copy the
		Corresponding Source from a network server at no charge.

		c) Convey individual copies of the object code with a copy of the
		written offer to provide the Corresponding Source.  This
		alternative is allowed only occasionally and noncommercially, and
		only if you received the object code with such an offer, in accord
		with subsection 6b.

		d) Convey the object code by offering access from a designated
		place (gratis or for a charge), and offer equivalent access to the
		Corresponding Source in the same way through the same place at no
		further charge.  You need not require recipients to copy the
		Corresponding Source along with the object code.  If the place to
		copy the object code is a network server, the Corresponding Source
		may be on a different server (operated by you or a third party)
		that supports equivalent copying facilities, provided you maintain
		clear directions next to the object code saying where to find the
		Corresponding Source.  Regardless of what server hosts the
		Corresponding Source, you remain obligated to ensure that it is
		available for as long as needed to satisfy these requirements.

		e) Convey the object code using peer-to-peer transmission, provided
		you inform other peers where the object code and Corresponding
		Source of the work are being offered to the general public at no
		charge under subsection 6d.

	  A separable portion of the object code, whose source code is excluded
	from the Corresponding Source as a System Library, need not be
	included in conveying the object code work.

	  A "User Product" is either (1) a "consumer product", which means any
	tangible personal property which is normally used for personal, family,
	or household purposes, or (2) anything designed or sold for incorporation
	into a dwelling.  In determining whether a product is a consumer product,
	doubtful cases shall be resolved in favor of coverage.  For a particular
	product received by a particular user, "normally used" refers to a
	typical or common use of that class of product, regardless of the status
	of the particular user or of the way in which the particular user
	actually uses, or expects or is expected to use, the product.  A product
	is a consumer product regardless of whether the product has substantial
	commercial, industrial or non-consumer uses, unless such uses represent
	the only significant mode of use of the product.

	  "Installation Information" for a User Product means any methods,
	procedures, authorization keys, or other information required to install
	and execute modified versions of a covered work in that User Product from
	a modified version of its Corresponding Source.  The information must
	suffice to ensure that the continued functioning of the modified object
	code is in no case prevented or interfered with solely because
	modification has been made.

	  If you convey an object code work under this section in, or with, or
	specifically for use in, a User Product, and the conveying occurs as
	part of a transaction in which the right of possession and use of the
	User Product is transferred to the recipient in perpetuity or for a
	fixed term (regardless of how the transaction is characterized), the
	Corresponding Source conveyed under this section must be accompanied
	by the Installation Information.  But this requirement does not apply
	if neither you nor any third party retains the ability to install
	modified object code on the User Product (for example, the work has
	been installed in ROM).

	  The requirement to provide Installation Information does not include a
	requirement to continue to provide support service, warranty, or updates
	for a work that has been modified or installed by the recipient, or for
	the User Product in which it has been modified or installed.  Access to a
	network may be denied when the modification itself materially and
	adversely affects the operation of the network or violates the rules and
	protocols for communication across the network.

	  Corresponding Source conveyed, and Installation Information provided,
	in accord with this section must be in a format that is publicly
	documented (and with an implementation available to the public in
	source code form), and must require no special password or key for
	unpacking, reading or copying.

	  7. Additional Terms.

	  "Additional permissions" are terms that supplement the terms of this
	License by making exceptions from one or more of its conditions.
	Additional permissions that are applicable to the entire Program shall
	be treated as though they were included in this License, to the extent
	that they are valid under applicable law.  If additional permissions
	apply only to part of the Program, that part may be used separately
	under those permissions, but the entire Program remains governed by
	this License without regard to the additional permissions.

	  When you convey a copy of a covered work, you may at your option
	remove any additional permissions from that copy, or from any part of
	it.  (Additional permissions may be written to require their own
	removal in certain cases when you modify the work.)  You may place
	additional permissions on material, added by you to a covered work,
	for which you have or can give appropriate copyright permission.

	  Notwithstanding any other provision of this License, for material you
	add to a covered work, you may (if authorized by the copyright holders of
	that material) supplement the terms of this License with terms:

		a) Disclaiming warranty or limiting liability differently from the
		terms of sections 15 and 16 of this License; or

		b) Requiring preservation of specified reasonable legal notices or
		author attributions in that material or in the Appropriate Legal
		Notices displayed by works containing it; or

		c) Prohibiting misrepresentation of the origin of that material, or
		requiring that modified versions of such material be marked in
		reasonable ways as different from the original version; or

		d) Limiting the use for publicity purposes of names of licensors or
		authors of the material; or

		e) Declining to grant rights under trademark law for use of some
		trade names, trademarks, or service marks; or

		f) Requiring indemnification of licensors and authors of that
		material by anyone who conveys the material (or modified versions of
		it) with contractual assumptions of liability to the recipient, for
		any liability that these contractual assumptions directly impose on
		those licensors and authors.

	  All other non-permissive additional terms are considered "further
	restrictions" within the meaning of section 10.  If the Program as you
	received it, or any part of it, contains a notice stating that it is
	governed by this License along with a term that is a further
	restriction, you may remove that term.  If a license document contains
	a further restriction but permits relicensing or conveying under this
	License, you may add to a covered work material governed by the terms
	of that license document, provided that the further restriction does
	not survive such relicensing or conveying.

	  If you add terms to a covered work in accord with this section, you
	must place, in the relevant source files, a statement of the
	additional terms that apply to those files, or a notice indicating
	where to find the applicable terms.

	  Additional terms, permissive or non-permissive, may be stated in the
	form of a separately written license, or stated as exceptions;
	the above requirements apply either way.

	  8. Termination.

	  You may not propagate or modify a covered work except as expressly
	provided under this License.  Any attempt otherwise to propagate or
	modify it is void, and will automatically terminate your rights under
	this License (including any patent licenses granted under the third
	paragraph of section 11).

	  However, if you cease all violation of this License, then your
	license from a particular copyright holder is reinstated (a)
	provisionally, unless and until the copyright holder explicitly and
	finally terminates your license, and (b) permanently, if the copyright
	holder fails to notify you of the violation by some reasonable means
	prior to 60 days after the cessation.

	  Moreover, your license from a particular copyright holder is
	reinstated permanently if the copyright holder notifies you of the
	violation by some reasonable means, this is the first time you have
	received notice of violation of this License (for any work) from that
	copyright holder, and you cure the violation prior to 30 days after
	your receipt of the notice.

	  Termination of your rights under this section does not terminate the
	licenses of parties who have received copies or rights from you under
	this License.  If your rights have been terminated and not permanently
	reinstated, you do not qualify to receive new licenses for the same
	material under section 10.

	  9. Acceptance Not Required for Having Copies.

	  You are not required to accept this License in order to receive or
	run a copy of the Program.  Ancillary propagation of a covered work
	occurring solely as a consequence of using peer-to-peer transmission
	to receive a copy likewise does not require acceptance.  However,
	nothing other than this License grants you permission to propagate or
	modify any covered work.  These actions infringe copyright if you do
	not accept this License.  Therefore, by modifying or propagating a
	covered work, you indicate your acceptance of this License to do so.

	  10. Automatic Licensing of Downstream Recipients.

	  Each time you convey a covered work, the recipient automatically
	receives a license from the original licensors, to run, modify and
	propagate that work, subject to this License.  You are not responsible
	for enforcing compliance by third parties with this License.

	  An "entity transaction" is a transaction transferring control of an
	organization, or substantially all assets of one, or subdividing an
	organization, or merging organizations.  If propagation of a covered
	work results from an entity transaction, each party to that
	transaction who receives a copy of the work also receives whatever
	licenses to the work the party's predecessor in interest had or could
	give under the previous paragraph, plus a right to possession of the
	Corresponding Source of the work from the predecessor in interest, if
	the predecessor has it or can get it with reasonable efforts.

	  You may not impose any further restrictions on the exercise of the
	rights granted or affirmed under this License.  For example, you may
	not impose a license fee, royalty, or other charge for exercise of
	rights granted under this License, and you may not initiate litigation
	(including a cross-claim or counterclaim in a lawsuit) alleging that
	any patent claim is infringed by making, using, selling, offering for
	sale, or importing the Program or any portion of it.

	  11. Patents.

	  A "contributor" is a copyright holder who authorizes use under this
	License of the Program or a work on which the Program is based.  The
	work thus licensed is called the contributor's "contributor version".

	  A contributor's "essential patent claims" are all patent claims
	owned or controlled by the contributor, whether already acquired or
	hereafter acquired, that would be infringed by some manner, permitted
	by this License, of making, using, or selling its contributor version,
	but do not include claims that would be infringed only as a
	consequence of further modification of the contributor version.  For
	purposes of this definition, "control" includes the right to grant
	patent sublicenses in a manner consistent with the requirements of
	this License.

	  Each contributor grants you a non-exclusive, worldwide, royalty-free
	patent license under the contributor's essential patent claims, to
	make, use, sell, offer for sale, import and otherwise run, modify and
	propagate the contents of its contributor version.

	  In the following three paragraphs, a "patent license" is any express
	agreement or commitment, however denominated, not to enforce a patent
	(such as an express permission to practice a patent or covenant not to
	sue for patent infringement).  To "grant" such a patent license to a
	party means to make such an agreement or commitment not to enforce a
	patent against the party.

	  If you convey a covered work, knowingly relying on a patent license,
	and the Corresponding Source of the work is not available for anyone
	to copy, free of charge and under the terms of this License, through a
	publicly available network server or other readily accessible means,
	then you must either (1) cause the Corresponding Source to be so
	available, or (2) arrange to deprive yourself of the benefit of the
	patent license for this particular work, or (3) arrange, in a manner
	consistent with the requirements of this License, to extend the patent
	license to downstream recipients.  "Knowingly relying" means you have
	actual knowledge that, but for the patent license, your conveying the
	covered work in a country, or your recipient's use of the covered work
	in a country, would infringe one or more identifiable patents in that
	country that you have reason to believe are valid.

	  If, pursuant to or in connection with a single transaction or
	arrangement, you convey, or propagate by procuring conveyance of, a
	covered work, and grant a patent license to some of the parties
	receiving the covered work authorizing them to use, propagate, modify
	or convey a specific copy of the covered work, then the patent license
	you grant is automatically extended to all recipients of the covered
	work and works based on it.

	  A patent license is "discriminatory" if it does not include within
	the scope of its coverage, prohibits the exercise of, or is
	conditioned on the non-exercise of one or more of the rights that are
	specifically granted under this License.  You may not convey a covered
	work if you are a party to an arrangement with a third party that is
	in the business of distributing software, under which you make payment
	to the third party based on the extent of your activity of conveying
	the work, and under which the third party grants, to any of the
	parties who would receive the covered work from you, a discriminatory
	patent license (a) in connection with copies of the covered work
	conveyed by you (or copies made from those copies), or (b) primarily
	for and in connection with specific products or compilations that
	contain the covered work, unless you entered into that arrangement,
	or that patent license was granted, prior to 28 March 2007.

	  Nothing in this License shall be construed as excluding or limiting
	any implied license or other defenses to infringement that may
	otherwise be available to you under applicable patent law.

	  12. No Surrender of Others' Freedom.

	  If conditions are imposed on you (whether by court order, agreement or
	otherwise) that contradict the conditions of this License, they do not
	excuse you from the conditions of this License.  If you cannot convey a
	covered work so as to satisfy simultaneously your obligations under this
	License and any other pertinent obligations, then as a consequence you may
	not convey it at all.  For example, if you agree to terms that obligate you
	to collect a royalty for further conveying from those to whom you convey
	the Program, the only way you could satisfy both those terms and this
	License would be to refrain entirely from conveying the Program.

	  13. Use with the GNU Affero General Public License.

	  Notwithstanding any other provision of this License, you have
	permission to link or combine any covered work with a work licensed
	under version 3 of the GNU Affero General Public License into a single
	combined work, and to convey the resulting work.  The terms of this
	License will continue to apply to the part which is the covered work,
	but the special requirements of the GNU Affero General Public License,
	section 13, concerning interaction through a network will apply to the
	combination as such.

	  14. Revised Versions of this License.

	  The Free Software Foundation may publish revised and/or new versions of
	the GNU General Public License from time to time.  Such new versions will
	be similar in spirit to the present version, but may differ in detail to
	address new problems or concerns.

	  Each version is given a distinguishing version number.  If the
	Program specifies that a certain numbered version of the GNU General
	Public License "or any later version" applies to it, you have the
	option of following the terms and conditions either of that numbered
	version or of any later version published by the Free Software
	Foundation.  If the Program does not specify a version number of the
	GNU General Public License, you may choose any version ever published
	by the Free Software Foundation.

	  If the Program specifies that a proxy can decide which future
	versions of the GNU General Public License can be used, that proxy's
	public statement of acceptance of a version permanently authorizes you
	to choose that version for the Program.

	  Later license versions may give you additional or different
	permissions.  However, no additional obligations are imposed on any
	author or copyright holder as a result of your choosing to follow a
	later version.

	  15. Disclaimer of Warranty.

	  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
	APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
	HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
	OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
	THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
	PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
	IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
	ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

	  16. Limitation of Liability.

	  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
	WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
	THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
	GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
	USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
	DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
	PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
	EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
	SUCH DAMAGES.

	  17. Interpretation of Sections 15 and 16.

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

						 END OF TERMS AND CONDITIONS

				How to Apply These Terms to Your New Programs

	  If you develop a new program, and you want it to be of the greatest
	possible use to the public, the best way to achieve this is to make it
	free software which everyone can redistribute and change under these terms.

	  To do so, attach the following notices to the program.  It is safest
	to attach them to the start of each source file to most effectively
	state the exclusion of warranty; and each file should have at least
	the "copyright" line and a pointer to where the full notice is found.

		<one line to give the program's name and a brief idea of what it does.>
		Copyright (C) <year>  <name of author>

		This program is free software: you can redistribute it and/or modify
		it under the terms of the GNU General Public License as published by
		the Free Software Foundation, either version 3 of the License, or
		(at your option) any later version.

		This program is distributed in the hope that it will be useful,
		but WITHOUT ANY WARRANTY; without even the implied warranty of
		MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
		GNU General Public License for more details.

		You should have received a copy of the GNU General Public License
		along with this program.  If not, see <https://www.gnu.org/licenses/>.

	Also add information on how to contact you by electronic and paper mail.

	  If the program does terminal interaction, make it output a short
	notice like this when it starts in an interactive mode:

		<program>  Copyright (C) <year>  <name of author>
		This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
		This is free software, and you are welcome to redistribute it
		under certain conditions; type `show c' for details.

	The hypothetical commands `show w' and `show c' should show the appropriate
	parts of the General Public License.  Of course, your program's commands
	might be different; for a GUI interface, you would use an "about box".

	  You should also get your employer (if you work as a programmer) or school,
	if any, to sign a "copyright disclaimer" for the program, if necessary.
	For more information on this, and how to apply and follow the GNU GPL, see
	<https://www.gnu.org/licenses/>.

	  The GNU General Public License does not permit incorporating your program
	into proprietary programs.  If your program is a subroutine library, you
	may consider it more useful to permit linking proprietary applications with
	the library.  If this is what you want to do, use the GNU Lesser General
	Public License instead of this License.  But first, please read
	<https://www.gnu.org/licenses/why-not-lgpl.html>.

"Privacy and security"
© Paul Boersma 2022

Praat is an “isolated” app. You download it from `praat.org`,
then record sounds into Praat (all in RAM) or open a sound file,
then analyse or manipulate that sound. The only way in which your results
are saved to disk (as e.g. a Pitch file, a TextGrid file, or a sound file),
is when you explicitly choose one of the #Save or #Export commands
from Praat’s menus; Praat will not by itself save any data files to disk
or send any information anywhere. When you create a picture in the Picture window,
the only way to move that picture anywhere else is if you save it explicitly
to a picture file (e.g. PNG) or if you Copy–Paste it to e.g. a text editing
app such as e.g. Microsoft Word; Praat will not by itself save any picture to disk
or to the clipboard or send any information anywhere.
Praat will run just fine on your computer if it does not have Internet access,
and in fact Praat cannot even notice whether you are in a network or not.
Praat works entirely stand-alone.

Praat does not call home
========================
When you are using Praat, you can be assured that Praat does not attempt to send any of your data
or pictures or settings to the Praat team.
In fact, Praat never accesses the Internet, not even to @@checking for updates|check for updates@.

No telemetry
============
Praat does not send anything to the Praat team while you are using Praat:
- No surveillance
- No tracking
- No Google Analytics
- In general, no spying or data mining by the Praat team

What does Praat save to disk without asking you?
================================================
Praat will save your preferences to your own disk on your own computer,
in a folder of your own, when you close Praat.
This includes the settings in your Sound window (e.g. your last chosen Pitch range),
so that your Sound windows will look the same after you start Praat up again.
The goal of this is to provide a continuous user experience, and is what you probably expect,
because most apps that you use on your computer work this way.

What we do measure
==================
As mentioned above, Praat does no telemetry, i.e. it does not send us anything while you are using Praat.
We %do% receive some information, though, when %you contact %us. This happens when you download
a new Praat version for your computer. We log the Praat downloads, so that we can potentially count
how often which edition and which version of Praat is downloaded.

Wouldn’t telemetry be useful for the quality of Praat?
======================================================
Companies that use telemetry tend to justify that by arguing that gathering information on how their app is used
is useful for improving the quality of their app (by collecting error messages),
or to know which features are rarely used, so that those features can be removed.

We are skeptical. If we, as Praat developers, have made a programming error,
then we hope that an “assertion” will help solve the issue.
An assertion is a place in our code where Praat will crash if a certain assumption
is not met. A message window will pop up in Praat that says that Praat will crash, together
with the request to send some relevant information by email to us, the developers of Praat.
If you do send this crash information on to us (you can read it, as it is normal English without secrets),
we will then virtually always find out (sometimes with some more help from you,
such as the sound file or script that caused the crash)
what was wrong, and correct the mistake, so that our programming error (“bug”) no longer occurs
in the next version of Praat. We will also build an automatable test that checks, for all future
versions of Praat, that the bug does not reappear. In this way, every Praat version tends to be more stable and correct
than the previous version. We believe that this practice minimizes the problems with Praat sufficiently,
and no automated reporting of error messages and crash messages is necessary.

As for the removal of obsolete features, we are just very conservative.
Typically, file types from the 1980s and 1990s can typically still be opened in the 2020s,
and old Praat scripts should continue to run for at least 15 years after we marked a language feature
as “deprecated” or “obsolete” (and removed it from the manual).
This has not prevented us from also being able to open file types invented in the 2020s
or to have a modern scripting language that supports vectors, matrices and string arrays,
and backward compatibility hardly hampers the continual modernization of Praat.

Praat scripts and plug-ins
==========================
As with R scripts, Python scripts, and quite generally any kinds of scripts from any source,
you should consider Praat scripts written by others, such as plug-ins that you download,
as separate apps with their own privacy and security issues. Use a script or plug-in only
if you completely trust that script or plug-in and its creators.

################################################################################
"Checking for updates"
© Paul Boersma 2022

Updates for Praat are available from `www.praat.org`.

Your current version (if you are reading this from the manual inside the Praat program,
rather than from the website) is )~~~" stringize(PRAAT_VERSION_STR) R"~~~(,
from )~~~" stringize(PRAAT_MONTH) " " stringize(PRAAT_DAY) ", " stringize(PRAAT_YEAR) R"~~~(.
Given that we tend to release new Praat versions once or twice a month,
you can probably guess whether it would be worth your while to have a look at `www.praat.org`
to see what is new, and perhaps download a new version.

Praat improves continually, and old features will almost always continue to work,
so there should never be a reason to continue to work with older versions.

Why no automatic update checking?
=================================
Many apps automatically check for updates when you start them up.
This means that the owners of such an app are capable of recording which users use their app when,
which is information that can potentially harm your privacy, for instance when a government
or legal investigation demands that the app owners provide them with access to such information.
The Praat team wants to stay far away from the possibility of such situations occurring,
even if you may be convinced that usage of the Praat program cannot be regarded by anybody
as being anything other than perfectly innocent. For this resason, the Praat program
will never contact the Praat team and, more generally,
will never attempt to access the Internet by itself. For more information, see @@Privacy and security@.

################################################################################
"Reporting a problem"
© Paul Boersma 2022

Anything that you consider incorrect behaviour of Praat (a “bug”) can be reported
to the authors by email (`paul.boersma@uva.nl`). This includes any crashes.

Questions about how to use Praat for your specific cases
can be posed to the Praat User List (`https://groups.io/g/Praat-Users-List`).
This includes any questions on why your self-written Praat script does something unexpected.
