-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.
-
-This version of the GNU Lesser General Public License incorporates the
-terms and conditions of version 3 of the GNU General Public License,
-supplemented by the additional permissions listed below.
-
-## 0. Additional Definitions.
-
-As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the
-GNU General Public License.
-
-"The Library" refers to a covered work governed by this License, other
-than an Application or a Combined Work as defined below.
-
-An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-A "Combined Work" is a work produced by combining or linking an
-Application with the Library. The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-## 1. Exception to Section 3 of the GNU GPL.
-
-You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-## 2. Conveying Modified Versions.
-
-If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
--   a) under this License, provided that you make a good faith effort
-    to ensure that, in the event an Application does not supply the
-    function or data, the facility still operates, and performs
-    whatever part of its purpose remains meaningful, or
--   b) under the GNU GPL, with none of the additional permissions of
-    this License applicable to that copy.
-
-## 3. Object Code Incorporating Material from Library Header Files.
-
-The object code form of an Application may incorporate material from a
-header file that is part of the Library. You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
--   a) Give prominent notice with each copy of the object code that
-    the Library is used in it and that the Library and its use are
-    covered by this License.
--   b) Accompany the object code with a copy of the GNU GPL and this
-    license document.
-
-## 4. Combined Works.
-
-You may convey a Combined Work under terms of your choice that, taken
-together, effectively do not restrict modification of the portions of
-the Library contained in the Combined Work and reverse engineering for
-debugging such modifications, if you also do each of the following:
-
--   a) Give prominent notice with each copy of the Combined Work that
-    the Library is used in it and that the Library and its use are
-    covered by this License.
--   b) Accompany the Combined Work with a copy of the GNU GPL and this
-    license document.
--   c) For a Combined Work that displays copyright notices during
-    execution, include the copyright notice for the Library among
-    these notices, as well as a reference directing the user to the
-    copies of the GNU GPL and this license document.
--   d) Do one of the following:
-    -   0) Convey the Minimal Corresponding Source under the terms of
-        this License, and the Corresponding Application Code in a form
-        suitable for, and under terms that permit, the user to
-        recombine or relink the Application with a modified version of
-        the Linked Version to produce a modified Combined Work, in the
-        manner specified by section 6 of the GNU GPL for conveying
-        Corresponding Source.
-    -   1) Use a suitable shared library mechanism for linking with
-        the Library. A suitable mechanism is one that (a) uses at run
-        time a copy of the Library already present on the user's
-        computer system, and (b) will operate properly with a modified
-        version of the Library that is interface-compatible with the
-        Linked Version.
--   e) Provide Installation Information, but only if you would
-    otherwise be required to provide such information under section 6
-    of the GNU GPL, and only to the extent that such information is
-    necessary to install and execute a modified version of the
-    Combined Work produced by recombining or relinking the Application
-    with a modified version of the Linked Version. (If you use option
-    4d0, the Installation Information must accompany the Minimal
-    Corresponding Source and Corresponding Application Code. If you
-    use option 4d1, you must provide the Installation Information in
-    the manner specified by section 6 of the GNU GPL for conveying
-    Corresponding Source.)
-
-## 5. Combined Libraries.
-
-You may place library facilities that are a work based on the Library
-side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
--   a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities, conveyed under the terms of this License.
--   b) Give prominent notice with the combined library that part of it
-    is a work based on the Library, and explaining where to find the
-    accompanying uncombined form of the same work.
-
-## 6. Revised Versions of the GNU Lesser General Public License.
-
-The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser 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 Library
-as you received it specifies that a certain numbered version of the
-GNU Lesser General Public License "or any later version" applies to
-it, you have the option of following the terms and conditions either
-of that published version or of any later version published by the
-Free Software Foundation. If the Library as you received it does not
-specify a version number of the GNU Lesser General Public License, you
-may choose any version of the GNU Lesser General Public License ever
-published by the Free Software Foundation.
-
-If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-Version 3, 29 June 2007

-<https://fsf.org/>

-
-## 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>.
