+OPYING file for VirtualBox versions 7.0 and later versions that include this
+file
+
+Preliminary notes:
+
+1) The majority of the code in the VirtualBox base package is licensed under
+the GNU General Public License, version 3 (GPL). VirtualBox contains many
+components developed by Oracle and various third parties. The license for
+each component is located in the licensing documentation and/or in the
+component's source code.
+
+2) As an exception to the reciprocal license obligations of the GPL listed
+below, you may use any VirtualBox header file that is marked by Oracle as
+licensed under both the GPL and the Common Development and Distribution
+License version 1.0 (CDDL) to invoke the unmodified VirtualBox libraries. In
+other words, calling such a multi-licensed interface by dynamically linking
+to the unmodified VirtualBox libraries is considered a normal use of
+VirtualBox and does not turn the calling code into a derived work of
+VirtualBox. In particular, this applies to code that wants to extend
+VirtualBox by way of the Extension Pack mechanism declared in the ExtPack.h
+header file.
+
+3) Whoever creates or distributes a derived work based on VirtualBox is not
+obligated to grant the above exceptions for such a version. The GPL permits
+you to release a modified version without the above exception; in addition,
+Oracle hereby also allows you to release a modified version which carries
+forward these exceptions.

+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

+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>.
