+<p>COPYING file for VirtualBox versions 7.0 and later versions
+that include this file</p>
+
+<p>Preliminary notes:</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>

+<p>GNU GENERAL PUBLIC LICENSE</p>
+
+<p>Version 3, 29 June 2007</p>
+
+<p>Copyright &copy; 2007 Free Software Foundation, Inc.
+&lt;https://fsf.org/&gt;</p>
+
+<p style='text-align:justify'>Everyone is permitted to copy and
+distribute verbatim copies of this license document, but changing it is not
+allowed.</p>
+
+<p>Preamble</p>
+
+<p>The GNU General Public License is a free, copyleft license
+for software and other kinds of works.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>The precise terms and conditions
+for copying, distribution and modification follow.</p>
+
+<p style='text-align:justify'>TERMS AND CONDITIONS</p>
+
+<p style='text-align:justify'>0. Definitions.</p>
+
+<p style='text-align:justify'>&ldquo;This License&rdquo; refers to version
+3 of the GNU General Public License.</p>
+
+<p style='text-align:justify'>&ldquo;Copyright&rdquo; also means
+copyright-like laws that apply to other kinds of works, such as semiconductor
+masks.</p>
+
+<p style='text-align:justify'>&ldquo;The Program&rdquo; refers to any
+copyrightable work licensed under this License. Each licensee is addressed as
+&ldquo;you&rdquo;. &ldquo;Licensees&rdquo; and &ldquo;recipients&rdquo; may be individuals or organizations.</p>
+
+<p style='text-align:justify'>To &ldquo;modify&rdquo; 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 &ldquo;modified version&rdquo; of the earlier work or a work &ldquo;based on&rdquo; the
+earlier work.</p>
+
+<p style='text-align:justify'>A &ldquo;covered work&rdquo; means either the
+unmodified Program or a work based on the Program.</p>
+
+<p style='text-align:justify'>To &ldquo;propagate&rdquo; 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.</p>
+
+<p style='text-align:justify'>To &ldquo;convey&rdquo; 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.</p>
+
+<p style='text-align:justify'>An interactive user interface
+displays &ldquo;Appropriate Legal Notices&rdquo; 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.</p>
+
+<p style='text-align:justify'>1. Source Code.</p>
+
+<p style='text-align:justify'>The &ldquo;source code&rdquo; for a work
+means the preferred form of the work for making modifications to it. &ldquo;Object
+code&rdquo; means any non-source form of a work.</p>
+
+<p style='text-align:justify'>A &ldquo;Standard Interface&rdquo; 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.</p>
+
+<p style='text-align:justify'>The &ldquo;System Libraries&rdquo; 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 &ldquo;Major
+Component&rdquo;, 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.</p>
+
+<p style='text-align:justify'>The &ldquo;Corresponding Source&rdquo; 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.</p>
+
+<p style='text-align:justify'>The Corresponding Source need not
+include anything that users can regenerate automatically from other parts of
+the Corresponding Source.</p>
+
+<p style='text-align:justify'>The Corresponding Source for a
+work in source code form is that same work.</p>
+
+<p style='text-align:justify'>2. Basic Permissions.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>Conveying under any other
+circumstances is permitted solely under the conditions stated below.
+Sublicensing is not allowed; section 10 makes it unnecessary.</p>
+
+<p style='text-align:justify'>3. Protecting Users' Legal Rights
+From Anti-Circumvention Law.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>4. Conveying Verbatim Copies.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>5. Conveying Modified Source
+Versions.</p>
+
+<p style='text-align:justify'>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:</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;a) The work must carry prominent notices
+stating that you modified it, and giving a relevant date.</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;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 &ldquo;keep
+intact all notices&rdquo;.</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;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.</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;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.</p>
+
+<p style='text-align:justify'>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 &ldquo;aggregate&rdquo; 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.</p>
+
+<p style='text-align:justify'>6. Conveying Non-Source Forms.</p>
+
+<p style='text-align:justify'>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:</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;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.</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;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.</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;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.</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;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.</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>A &ldquo;User Product&rdquo; is either (1) a
+&ldquo;consumer product&rdquo;, 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, &ldquo;normally
+used&rdquo; 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.</p>
+
+<p style='text-align:justify'>&ldquo;Installation Information&rdquo; 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.</p>
+
+<p style='text-align:justify'>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).</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>7. Additional Terms.</p>
+
+<p style='text-align:justify'>&ldquo;Additional permissions&rdquo; 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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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:</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;a) Disclaiming warranty or limiting
+liability differently from the terms of sections 15 and 16 of this License; or</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;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</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;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</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;d) Limiting the use for publicity purposes
+of names of licensors or authors of the material; or</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;e) Declining to grant rights under
+trademark law for use of some trade names, trademarks, or service marks; or</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;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.</p>
+
+<p style='text-align:justify'>All other non-permissive
+additional terms are considered &ldquo;further restrictions&rdquo; 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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>8. Termination.</p>
+
+<p style='text-align:justify'>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).</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>9. Acceptance Not Required for
+Having Copies.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>10. Automatic Licensing of
+Downstream Recipients.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>An &ldquo;entity transaction&rdquo; 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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>11. Patents.</p>
+
+<p style='text-align:justify'>A &ldquo;contributor&rdquo; 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
+&ldquo;contributor version&rdquo;.</p>
+
+<p style='text-align:justify'>A contributor's &ldquo;essential patent
+claims&rdquo; 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, &ldquo;control&rdquo; includes the right to grant patent sublicenses in a
+manner consistent with the requirements of this License.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>In the following three
+paragraphs, a &ldquo;patent license&rdquo; 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 &ldquo;grant&rdquo; such a
+patent license to a party means to make such an agreement or commitment not to
+enforce a patent against the party.</p>
+
+<p style='text-align:justify'>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. &ldquo;Knowingly relying&rdquo; 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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>A patent license is
+&ldquo;discriminatory&rdquo; 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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>12. No Surrender of Others'
+Freedom.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>13. Use with the GNU Affero General Public
+License.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>14. Revised Versions of this
+License.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>Each version is given a
+distinguishing version number. If the Program specifies that a certain numbered
+version of the GNU General Public License &ldquo;or any later version&rdquo; 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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>15. Disclaimer of Warranty.</p>
+
+<p style='text-align:justify'>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 &ldquo;AS IS&rdquo; 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.</p>
+
+<p style='text-align:justify'>16. Limitation of Liability.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>17. Interpretation of Sections 15
+and 16.</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>END OF TERMS AND CONDITIONS</p>
+
+<p style='text-align:justify'>How to Apply These Terms to Your
+New Programs</p>
+
+<p style='text-align:justify'>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.</p>
+
+<p style='text-align:justify'>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 &ldquo;copyright&rdquo; line and a pointer to where the full notice is found.</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;&lt;one line to give the program's name and
+a brief idea of what it does.&gt;</p>
+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;Copyright (C) &lt;year&gt; &lt;name of author&gt;</p>

+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;This program is distributed in the hope

+
+<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;You should have received a copy of the GNU

+
+<p style='text-align:justify'>Also add information on how to
+contact you by electronic and paper mail.</p>
+
+<p style='text-align:justify'>If the program does terminal
+interaction, make it output a short notice like this when it starts in an
+interactive mode:</p>

+details.</p>
+
+<p style='text-align:justify'>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 &ldquo;about box&rdquo;.</p>
+
+<p style='text-align:justify'>You should also get your employer
+(if you work as a programmer) or school, if any, to sign a &ldquo;copyright
+disclaimer&rdquo; for the program, if necessary. For more information on this, and
+how to apply and follow the GNU GPL, see &lt;https://www.gnu.org/licenses/&gt;.</p>
+
+<p style='text-align:justify'>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
