								                    GNU GENERAL PUBLIC LICENSE
							 | 
						|
								                       Version 3, 29 June 2007
							 | 
						|
								
							 | 
						|
								 Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
							 | 
						|
								 Everyone is permitted to copy and distribute verbatim copies
							 | 
						|
								 of this license document, but changing it is not allowed.
							 | 
						|
								
							 | 
						|
								                            Preamble
							 | 
						|
								
							 | 
						|
								  The GNU General Public License is a free, copyleft license for
							 | 
						|
								software and other kinds of works.
							 | 
						|
								
							 | 
						|
								  The licenses for most software and other practical works are designed
							 | 
						|
								to take away your freedom to share and change the works.  By contrast,
							 | 
						|
								the GNU General Public License is intended to guarantee your freedom to
							 | 
						|
								share and change all versions of a program--to make sure it remains free
							 | 
						|
								software for all its users.  We, the Free Software Foundation, use the
							 | 
						|
								GNU General Public License for most of our software; it applies also to
							 | 
						|
								any other work released this way by its authors.  You can apply it to
							 | 
						|
								your programs, too.
							 | 
						|
								
							 | 
						|
								  When we speak of free software, we are referring to freedom, not
							 | 
						|
								price.  Our General Public Licenses are designed to make sure that you
							 | 
						|
								have the freedom to distribute copies of free software (and charge for
							 | 
						|
								them if you wish), that you receive source code or can get it if you
							 | 
						|
								want it, that you can change the software or use pieces of it in new
							 | 
						|
								free programs, and that you know you can do these things.
							 | 
						|
								
							 | 
						|
								  To protect your rights, we need to prevent others from denying you
							 | 
						|
								these rights or asking you to surrender the rights.  Therefore, you have
							 | 
						|
								certain responsibilities if you distribute copies of the software, or if
							 | 
						|
								you modify it: responsibilities to respect the freedom of others.
							 | 
						|
								
							 | 
						|
								  For example, if you distribute copies of such a program, whether
							 | 
						|
								gratis or for a fee, you must pass on to the recipients the same
							 | 
						|
								freedoms that you received.  You must make sure that they, too, receive
							 | 
						|
								or can get the source code.  And you must show them these terms so they
							 | 
						|
								know their rights.
							 | 
						|
								
							 | 
						|
								  Developers that use the GNU GPL protect your rights with two steps:
							 | 
						|
								(1) assert copyright on the software, and (2) offer you this License
							 | 
						|
								giving you legal permission to copy, distribute and/or modify it.
							 | 
						|
								
							 | 
						|
								  For the developers' and authors' protection, the GPL clearly explains
							 | 
						|
								that there is no warranty for this free software.  For both users' and
							 | 
						|
								authors' sake, the GPL requires that modified versions be marked as
							 | 
						|
								changed, so that their problems will not be attributed erroneously to
							 | 
						|
								authors of previous versions.
							 | 
						|
								
							 | 
						|
								  Some devices are designed to deny users access to install or run
							 | 
						|
								modified versions of the software inside them, although the manufacturer
							 | 
						|
								can do so.  This is fundamentally incompatible with the aim of
							 | 
						|
								protecting users' freedom to change the software.  The systematic
							 | 
						|
								pattern of such abuse occurs in the area of products for individuals to
							 | 
						|
								use, which is precisely where it is most unacceptable.  Therefore, we
							 | 
						|
								have designed this version of the GPL to prohibit the practice for those
							 | 
						|
								products.  If such problems arise substantially in other domains, we
							 | 
						|
								stand ready to extend this provision to those domains in future versions
							 | 
						|
								of the GPL, as needed to protect the freedom of users.
							 | 
						|
								
							 | 
						|
								  Finally, every program is threatened constantly by software patents.
							 | 
						|
								States should not allow patents to restrict development and use of
							 | 
						|
								software on general-purpose computers, but in those that do, we wish to
							 | 
						|
								avoid the special danger that patents applied to a free program could
							 | 
						|
								make it effectively proprietary.  To prevent this, the GPL assures that
							 | 
						|
								patents cannot be used to render the program non-free.
							 | 
						|
								
							 | 
						|
								  The precise terms and conditions for copying, distribution and
							 | 
						|
								modification follow.
							 | 
						|
								
							 | 
						|
								                       TERMS AND CONDITIONS
							 | 
						|
								
							 | 
						|
								  0. Definitions.
							 | 
						|
								
							 | 
						|
								  "This License" refers to version 3 of the GNU General Public License.
							 | 
						|
								
							 | 
						|
								  "Copyright" also means copyright-like laws that apply to other kinds of
							 | 
						|
								works, such as semiconductor masks.
							 | 
						|
								
							 | 
						|
								  "The Program" refers to any copyrightable work licensed under this
							 | 
						|
								License.  Each licensee is addressed as "you".  "Licensees" and
							 | 
						|
								"recipients" may be individuals or organizations.
							 | 
						|
								
							 | 
						|
								  To "modify" a work means to copy from or adapt all or part of the work
							 | 
						|
								in a fashion requiring copyright permission, other than the making of an
							 | 
						|
								exact copy.  The resulting work is called a "modified version" of the
							 | 
						|
								earlier work or a work "based on" the earlier work.
							 | 
						|
								
							 | 
						|
								  A "covered work" means either the unmodified Program or a work based
							 | 
						|
								on the Program.
							 | 
						|
								
							 | 
						|
								  To "propagate" a work means to do anything with it that, without
							 | 
						|
								permission, would make you directly or secondarily liable for
							 | 
						|
								infringement under applicable copyright law, except executing it on a
							 | 
						|
								computer or modifying a private copy.  Propagation includes copying,
							 | 
						|
								distribution (with or without modification), making available to the
							 | 
						|
								public, and in some countries other activities as well.
							 | 
						|
								
							 | 
						|
								  To "convey" a work means any kind of propagation that enables other
							 | 
						|
								parties to make or receive copies.  Mere interaction with a user through
							 | 
						|
								a computer network, with no transfer of a copy, is not conveying.
							 | 
						|
								
							 | 
						|
								  An interactive user interface displays "Appropriate Legal Notices"
							 | 
						|
								to the extent that it includes a convenient and prominently visible
							 | 
						|
								feature that (1) displays an appropriate copyright notice, and (2)
							 | 
						|
								tells the user that there is no warranty for the work (except to the
							 | 
						|
								extent that warranties are provided), that licensees may convey the
							 | 
						|
								work under this License, and how to view a copy of this License.  If
							 | 
						|
								the interface presents a list of user commands or options, such as a
							 | 
						|
								menu, a prominent item in the list meets this criterion.
							 | 
						|
								
							 | 
						|
								  1. Source Code.
							 | 
						|
								
							 | 
						|
								  The "source code" for a work means the preferred form of the work
							 | 
						|
								for making modifications to it.  "Object code" means any non-source
							 | 
						|
								form of a work.
							 | 
						|
								
							 | 
						|
								  A "Standard Interface" means an interface that either is an official
							 | 
						|
								standard defined by a recognized standards body, or, in the case of
							 | 
						|
								interfaces specified for a particular programming language, one that
							 | 
						|
								is widely used among developers working in that language.
							 | 
						|
								
							 | 
						|
								  The "System Libraries" of an executable work include anything, other
							 | 
						|
								than the work as a whole, that (a) is included in the normal form of
							 | 
						|
								packaging a Major Component, but which is not part of that Major
							 | 
						|
								Component, and (b) serves only to enable use of the work with that
							 | 
						|
								Major Component, or to implement a Standard Interface for which an
							 | 
						|
								implementation is available to the public in source code form.  A
							 | 
						|
								"Major Component", in this context, means a major essential component
							 | 
						|
								(kernel, window system, and so on) of the specific operating system
							 | 
						|
								(if any) on which the executable work runs, or a compiler used to
							 | 
						|
								produce the work, or an object code interpreter used to run it.
							 | 
						|
								
							 | 
						|
								  The "Corresponding Source" for a work in object code form means all
							 | 
						|
								the source code needed to generate, install, and (for an executable
							 | 
						|
								work) run the object code and to modify the work, including scripts to
							 | 
						|
								control those activities.  However, it does not include the work's
							 | 
						|
								System Libraries, or general-purpose tools or generally available free
							 | 
						|
								programs which are used unmodified in performing those activities but
							 | 
						|
								which are not part of the work.  For example, Corresponding Source
							 | 
						|
								includes interface definition files associated with source files for
							 | 
						|
								the work, and the source code for shared libraries and dynamically
							 | 
						|
								linked subprograms that the work is specifically designed to require,
							 | 
						|
								such as by intimate data communication or control flow between those
							 | 
						|
								subprograms and other parts of the work.
							 | 
						|
								
							 | 
						|
								  The Corresponding Source need not include anything that users
							 | 
						|
								can regenerate automatically from other parts of the Corresponding
							 | 
						|
								Source.
							 | 
						|
								
							 | 
						|
								  The Corresponding Source for a work in source code form is that
							 | 
						|
								same work.
							 | 
						|
								
							 | 
						|
								  2. Basic Permissions.
							 | 
						|
								
							 | 
						|
								  All rights granted under this License are granted for the term of
							 | 
						|
								copyright on the Program, and are irrevocable provided the stated
							 | 
						|
								conditions are met.  This License explicitly affirms your unlimited
							 | 
						|
								permission to run the unmodified Program.  The output from running a
							 | 
						|
								covered work is covered by this License only if the output, given its
							 | 
						|
								content, constitutes a covered work.  This License acknowledges your
							 | 
						|
								rights of fair use or other equivalent, as provided by copyright law.
							 | 
						|
								
							 | 
						|
								  You may make, run and propagate covered works that you do not
							 | 
						|
								convey, without conditions so long as your license otherwise remains
							 | 
						|
								in force.  You may convey covered works to others for the sole purpose
							 | 
						|
								of having them make modifications exclusively for you, or provide you
							 | 
						|
								with facilities for running those works, provided that you comply with
							 | 
						|
								the terms of this License in conveying all material for which you do
							 | 
						|
								not control copyright.  Those thus making or running the covered works
							 | 
						|
								for you must do so exclusively on your behalf, under your direction
							 | 
						|
								and control, on terms that prohibit them from making any copies of
							 | 
						|
								your copyrighted material outside their relationship with you.
							 | 
						|
								
							 | 
						|
								  Conveying under any other circumstances is permitted solely under
							 | 
						|
								the conditions stated below.  Sublicensing is not allowed; section 10
							 | 
						|
								makes it unnecessary.
							 | 
						|
								
							 | 
						|
								  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
							 | 
						|
								
							 | 
						|
								  No covered work shall be deemed part of an effective technological
							 | 
						|
								measure under any applicable law fulfilling obligations under article
							 | 
						|
								11 of the WIPO copyright treaty adopted on 20 December 1996, or
							 | 
						|
								similar laws prohibiting or restricting circumvention of such
							 | 
						|
								measures.
							 | 
						|
								
							 | 
						|
								  When you convey a covered work, you waive any legal power to forbid
							 | 
						|
								circumvention of technological measures to the extent such circumvention
							 | 
						|
								is effected by exercising rights under this License with respect to
							 | 
						|
								the covered work, and you disclaim any intention to limit operation or
							 | 
						|
								modification of the work as a means of enforcing, against the work's
							 | 
						|
								users, your or third parties' legal rights to forbid circumvention of
							 | 
						|
								technological measures.
							 | 
						|
								
							 | 
						|
								  4. Conveying Verbatim Copies.
							 | 
						|
								
							 | 
						|
								  You may convey verbatim copies of the Program's source code as you
							 | 
						|
								receive it, in any medium, provided that you conspicuously and
							 | 
						|
								appropriately publish on each copy an appropriate copyright notice;
							 | 
						|
								keep intact all notices stating that this License and any
							 | 
						|
								non-permissive terms added in accord with section 7 apply to the code;
							 | 
						|
								keep intact all notices of the absence of any warranty; and give all
							 | 
						|
								recipients a copy of this License along with the Program.
							 | 
						|
								
							 | 
						|
								  You may charge any price or no price for each copy that you convey,
							 | 
						|
								and you may offer support or warranty protection for a fee.
							 | 
						|
								
							 | 
						|
								  5. Conveying Modified Source Versions.
							 | 
						|
								
							 | 
						|
								  You may convey a work based on the Program, or the modifications to
							 | 
						|
								produce it from the Program, in the form of source code under the
							 | 
						|
								terms of section 4, provided that you also meet all of these conditions:
							 | 
						|
								
							 | 
						|
								    a) The work must carry prominent notices stating that you modified
							 | 
						|
								    it, and giving a relevant date.
							 | 
						|
								
							 | 
						|
								    b) The work must carry prominent notices stating that it is
							 | 
						|
								    released under this License and any conditions added under section
							 | 
						|
								    7.  This requirement modifies the requirement in section 4 to
							 | 
						|
								    "keep intact all notices".
							 | 
						|
								
							 | 
						|
								    c) You must license the entire work, as a whole, under this
							 | 
						|
								    License to anyone who comes into possession of a copy.  This
							 | 
						|
								    License will therefore apply, along with any applicable section 7
							 | 
						|
								    additional terms, to the whole of the work, and all its parts,
							 | 
						|
								    regardless of how they are packaged.  This License gives no
							 | 
						|
								    permission to license the work in any other way, but it does not
							 | 
						|
								    invalidate such permission if you have separately received it.
							 | 
						|
								
							 | 
						|
								    d) If the work has interactive user interfaces, each must display
							 | 
						|
								    Appropriate Legal Notices; however, if the Program has interactive
							 | 
						|
								    interfaces that do not display Appropriate Legal Notices, your
							 | 
						|
								    work need not make them do so.
							 | 
						|
								
							 | 
						|
								  A compilation of a covered work with other separate and independent
							 | 
						|
								works, which are not by their nature extensions of the covered work,
							 | 
						|
								and which are not combined with it such as to form a larger program,
							 | 
						|
								in or on a volume of a storage or distribution medium, is called an
							 | 
						|
								"aggregate" if the compilation and its resulting copyright are not
							 | 
						|
								used to limit the access or legal rights of the compilation's users
							 | 
						|
								beyond what the individual works permit.  Inclusion of a covered work
							 | 
						|
								in an aggregate does not cause this License to apply to the other
							 | 
						|
								parts of the aggregate.
							 | 
						|
								
							 | 
						|
								  6. Conveying Non-Source Forms.
							 | 
						|
								
							 | 
						|
								  You may convey a covered work in object code form under the terms
							 | 
						|
								of sections 4 and 5, provided that you also convey the
							 | 
						|
								machine-readable Corresponding Source under the terms of this License,
							 | 
						|
								in one of these ways:
							 | 
						|
								
							 | 
						|
								    a) Convey the object code in, or embodied in, a physical product
							 | 
						|
								    (including a physical distribution medium), accompanied by the
							 | 
						|
								    Corresponding Source fixed on a durable physical medium
							 | 
						|
								    customarily used for software interchange.
							 | 
						|
								
							 | 
						|
								    b) Convey the object code in, or embodied in, a physical product
							 | 
						|
								    (including a physical distribution medium), accompanied by a
							 | 
						|
								    written offer, valid for at least three years and valid for as
							 | 
						|
								    long as you offer spare parts or customer support for that product
							 | 
						|
								    model, to give anyone who possesses the object code either (1) a
							 | 
						|
								    copy of the Corresponding Source for all the software in the
							 | 
						|
								    product that is covered by this License, on a durable physical
							 | 
						|
								    medium customarily used for software interchange, for a price no
							 | 
						|
								    more than your reasonable cost of physically performing this
							 | 
						|
								    conveying of source, or (2) access to copy the
							 | 
						|
								    Corresponding Source from a network server at no charge.
							 | 
						|
								
							 | 
						|
								    c) Convey individual copies of the object code with a copy of the
							 | 
						|
								    written offer to provide the Corresponding Source.  This
							 | 
						|
								    alternative is allowed only occasionally and noncommercially, and
							 | 
						|
								    only if you received the object code with such an offer, in accord
							 | 
						|
								    with subsection 6b.
							 | 
						|
								
							 | 
						|
								    d) Convey the object code by offering access from a designated
							 | 
						|
								    place (gratis or for a charge), and offer equivalent access to the
							 | 
						|
								    Corresponding Source in the same way through the same place at no
							 | 
						|
								    further charge.  You need not require recipients to copy the
							 | 
						|
								    Corresponding Source along with the object code.  If the place to
							 | 
						|
								    copy the object code is a network server, the Corresponding Source
							 | 
						|
								    may be on a different server (operated by you or a third party)
							 | 
						|
								    that supports equivalent copying facilities, provided you maintain
							 | 
						|
								    clear directions next to the object code saying where to find the
							 | 
						|
								    Corresponding Source.  Regardless of what server hosts the
							 | 
						|
								    Corresponding Source, you remain obligated to ensure that it is
							 | 
						|
								    available for as long as needed to satisfy these requirements.
							 | 
						|
								
							 | 
						|
								    e) Convey the object code using peer-to-peer transmission, provided
							 | 
						|
								    you inform other peers where the object code and Corresponding
							 | 
						|
								    Source of the work are being offered to the general public at no
							 | 
						|
								    charge under subsection 6d.
							 | 
						|
								
							 | 
						|
								  A separable portion of the object code, whose source code is excluded
							 | 
						|
								from the Corresponding Source as a System Library, need not be
							 | 
						|
								included in conveying the object code work.
							 | 
						|
								
							 | 
						|
								  A "User Product" is either (1) a "consumer product", which means any
							 | 
						|
								tangible personal property which is normally used for personal, family,
							 | 
						|
								or household purposes, or (2) anything designed or sold for incorporation
							 | 
						|
								into a dwelling.  In determining whether a product is a consumer product,
							 | 
						|
								doubtful cases shall be resolved in favor of coverage.  For a particular
							 | 
						|
								product received by a particular user, "normally used" refers to a
							 | 
						|
								typical or common use of that class of product, regardless of the status
							 | 
						|
								of the particular user or of the way in which the particular user
							 | 
						|
								actually uses, or expects or is expected to use, the product.  A product
							 | 
						|
								is a consumer product regardless of whether the product has substantial
							 | 
						|
								commercial, industrial or non-consumer uses, unless such uses represent
							 | 
						|
								the only significant mode of use of the product.
							 | 
						|
								
							 | 
						|
								  "Installation Information" for a User Product means any methods,
							 | 
						|
								procedures, authorization keys, or other information required to install
							 | 
						|
								and execute modified versions of a covered work in that User Product from
							 | 
						|
								a modified version of its Corresponding Source.  The information must
							 | 
						|
								suffice to ensure that the continued functioning of the modified object
							 | 
						|
								code is in no case prevented or interfered with solely because
							 | 
						|
								modification has been made.
							 | 
						|
								
							 | 
						|
								  If you convey an object code work under this section in, or with, or
							 | 
						|
								specifically for use in, a User Product, and the conveying occurs as
							 | 
						|
								part of a transaction in which the right of possession and use of the
							 | 
						|
								User Product is transferred to the recipient in perpetuity or for a
							 | 
						|
								fixed term (regardless of how the transaction is characterized), the
							 | 
						|
								Corresponding Source conveyed under this section must be accompanied
							 | 
						|
								by the Installation Information.  But this requirement does not apply
							 | 
						|
								if neither you nor any third party retains the ability to install
							 | 
						|
								modified object code on the User Product (for example, the work has
							 | 
						|
								been installed in ROM).
							 | 
						|
								
							 | 
						|
								  The requirement to provide Installation Information does not include a
							 | 
						|
								requirement to continue to provide support service, warranty, or updates
							 | 
						|
								for a work that has been modified or installed by the recipient, or for
							 | 
						|
								the User Product in which it has been modified or installed.  Access to a
							 | 
						|
								network may be denied when the modification itself materially and
							 | 
						|
								adversely affects the operation of the network or violates the rules and
							 | 
						|
								protocols for communication across the network.
							 | 
						|
								
							 | 
						|
								  Corresponding Source conveyed, and Installation Information provided,
							 | 
						|
								in accord with this section must be in a format that is publicly
							 | 
						|
								documented (and with an implementation available to the public in
							 | 
						|
								source code form), and must require no special password or key for
							 | 
						|
								unpacking, reading or copying.
							 | 
						|
								
							 | 
						|
								  7. Additional Terms.
							 | 
						|
								
							 | 
						|
								  "Additional permissions" are terms that supplement the terms of this
							 | 
						|
								License by making exceptions from one or more of its conditions.
							 | 
						|
								Additional permissions that are applicable to the entire Program shall
							 | 
						|
								be treated as though they were included in this License, to the extent
							 | 
						|
								that they are valid under applicable law.  If additional permissions
							 | 
						|
								apply only to part of the Program, that part may be used separately
							 | 
						|
								under those permissions, but the entire Program remains governed by
							 | 
						|
								this License without regard to the additional permissions.
							 | 
						|
								
							 | 
						|
								  When you convey a copy of a covered work, you may at your option
							 | 
						|
								remove any additional permissions from that copy, or from any part of
							 | 
						|
								it.  (Additional permissions may be written to require their own
							 | 
						|
								removal in certain cases when you modify the work.)  You may place
							 | 
						|
								additional permissions on material, added by you to a covered work,
							 | 
						|
								for which you have or can give appropriate copyright permission.
							 | 
						|
								
							 | 
						|
								  Notwithstanding any other provision of this License, for material you
							 | 
						|
								add to a covered work, you may (if authorized by the copyright holders of
							 | 
						|
								that material) supplement the terms of this License with terms:
							 | 
						|
								
							 | 
						|
								    a) Disclaiming warranty or limiting liability differently from the
							 | 
						|
								    terms of sections 15 and 16 of this License; or
							 | 
						|
								
							 | 
						|
								    b) Requiring preservation of specified reasonable legal notices or
							 | 
						|
								    author attributions in that material or in the Appropriate Legal
							 | 
						|
								    Notices displayed by works containing it; or
							 | 
						|
								
							 | 
						|
								    c) Prohibiting misrepresentation of the origin of that material, or
							 | 
						|
								    requiring that modified versions of such material be marked in
							 | 
						|
								    reasonable ways as different from the original version; or
							 | 
						|
								
							 | 
						|
								    d) Limiting the use for publicity purposes of names of licensors or
							 | 
						|
								    authors of the material; or
							 | 
						|
								
							 | 
						|
								    e) Declining to grant rights under trademark law for use of some
							 | 
						|
								    trade names, trademarks, or service marks; or
							 | 
						|
								
							 | 
						|
								    f) Requiring indemnification of licensors and authors of that
							 | 
						|
								    material by anyone who conveys the material (or modified versions of
							 | 
						|
								    it) with contractual assumptions of liability to the recipient, for
							 | 
						|
								    any liability that these contractual assumptions directly impose on
							 | 
						|
								    those licensors and authors.
							 | 
						|
								
							 | 
						|
								  All other non-permissive additional terms are considered "further
							 | 
						|
								restrictions" within the meaning of section 10.  If the Program as you
							 | 
						|
								received it, or any part of it, contains a notice stating that it is
							 | 
						|
								governed by this License along with a term that is a further
							 | 
						|
								restriction, you may remove that term.  If a license document contains
							 | 
						|
								a further restriction but permits relicensing or conveying under this
							 | 
						|
								License, you may add to a covered work material governed by the terms
							 | 
						|
								of that license document, provided that the further restriction does
							 | 
						|
								not survive such relicensing or conveying.
							 | 
						|
								
							 | 
						|
								  If you add terms to a covered work in accord with this section, you
							 | 
						|
								must place, in the relevant source files, a statement of the
							 | 
						|
								additional terms that apply to those files, or a notice indicating
							 | 
						|
								where to find the applicable terms.
							 | 
						|
								
							 | 
						|
								  Additional terms, permissive or non-permissive, may be stated in the
							 | 
						|
								form of a separately written license, or stated as exceptions;
							 | 
						|
								the above requirements apply either way.
							 | 
						|
								
							 | 
						|
								  8. Termination.
							 | 
						|
								
							 | 
						|
								  You may not propagate or modify a covered work except as expressly
							 | 
						|
								provided under this License.  Any attempt otherwise to propagate or
							 | 
						|
								modify it is void, and will automatically terminate your rights under
							 | 
						|
								this License (including any patent licenses granted under the third
							 | 
						|
								paragraph of section 11).
							 | 
						|
								
							 | 
						|
								  However, if you cease all violation of this License, then your
							 | 
						|
								license from a particular copyright holder is reinstated (a)
							 | 
						|
								provisionally, unless and until the copyright holder explicitly and
							 | 
						|
								finally terminates your license, and (b) permanently, if the copyright
							 | 
						|
								holder fails to notify you of the violation by some reasonable means
							 | 
						|
								prior to 60 days after the cessation.
							 | 
						|
								
							 | 
						|
								  Moreover, your license from a particular copyright holder is
							 | 
						|
								reinstated permanently if the copyright holder notifies you of the
							 | 
						|
								violation by some reasonable means, this is the first time you have
							 | 
						|
								received notice of violation of this License (for any work) from that
							 | 
						|
								copyright holder, and you cure the violation prior to 30 days after
							 | 
						|
								your receipt of the notice.
							 | 
						|
								
							 | 
						|
								  Termination of your rights under this section does not terminate the
							 | 
						|
								licenses of parties who have received copies or rights from you under
							 | 
						|
								this License.  If your rights have been terminated and not permanently
							 | 
						|
								reinstated, you do not qualify to receive new licenses for the same
							 | 
						|
								material under section 10.
							 | 
						|
								
							 | 
						|
								  9. Acceptance Not Required for Having Copies.
							 | 
						|
								
							 | 
						|
								  You are not required to accept this License in order to receive or
							 | 
						|
								run a copy of the Program.  Ancillary propagation of a covered work
							 | 
						|
								occurring solely as a consequence of using peer-to-peer transmission
							 | 
						|
								to receive a copy likewise does not require acceptance.  However,
							 | 
						|
								nothing other than this License grants you permission to propagate or
							 | 
						|
								modify any covered work.  These actions infringe copyright if you do
							 | 
						|
								not accept this License.  Therefore, by modifying or propagating a
							 | 
						|
								covered work, you indicate your acceptance of this License to do so.
							 | 
						|
								
							 | 
						|
								  10. Automatic Licensing of Downstream Recipients.
							 | 
						|
								
							 | 
						|
								  Each time you convey a covered work, the recipient automatically
							 | 
						|
								receives a license from the original licensors, to run, modify and
							 | 
						|
								propagate that work, subject to this License.  You are not responsible
							 | 
						|
								for enforcing compliance by third parties with this License.
							 | 
						|
								
							 | 
						|
								  An "entity transaction" is a transaction transferring control of an
							 | 
						|
								organization, or substantially all assets of one, or subdividing an
							 | 
						|
								organization, or merging organizations.  If propagation of a covered
							 | 
						|
								work results from an entity transaction, each party to that
							 | 
						|
								transaction who receives a copy of the work also receives whatever
							 | 
						|
								licenses to the work the party's predecessor in interest had or could
							 | 
						|
								give under the previous paragraph, plus a right to possession of the
							 | 
						|
								Corresponding Source of the work from the predecessor in interest, if
							 | 
						|
								the predecessor has it or can get it with reasonable efforts.
							 | 
						|
								
							 | 
						|
								  You may not impose any further restrictions on the exercise of the
							 | 
						|
								rights granted or affirmed under this License.  For example, you may
							 | 
						|
								not impose a license fee, royalty, or other charge for exercise of
							 | 
						|
								rights granted under this License, and you may not initiate litigation
							 | 
						|
								(including a cross-claim or counterclaim in a lawsuit) alleging that
							 | 
						|
								any patent claim is infringed by making, using, selling, offering for
							 | 
						|
								sale, or importing the Program or any portion of it.
							 | 
						|
								
							 | 
						|
								  11. Patents.
							 | 
						|
								
							 | 
						|
								  A "contributor" is a copyright holder who authorizes use under this
							 | 
						|
								License of the Program or a work on which the Program is based.  The
							 | 
						|
								work thus licensed is called the contributor's "contributor version".
							 | 
						|
								
							 | 
						|
								  A contributor's "essential patent claims" are all patent claims
							 | 
						|
								owned or controlled by the contributor, whether already acquired or
							 | 
						|
								hereafter acquired, that would be infringed by some manner, permitted
							 | 
						|
								by this License, of making, using, or selling its contributor version,
							 | 
						|
								but do not include claims that would be infringed only as a
							 | 
						|
								consequence of further modification of the contributor version.  For
							 | 
						|
								purposes of this definition, "control" includes the right to grant
							 | 
						|
								patent sublicenses in a manner consistent with the requirements of
							 | 
						|
								this License.
							 | 
						|
								
							 | 
						|
								  Each contributor grants you a non-exclusive, worldwide, royalty-free
							 | 
						|
								patent license under the contributor's essential patent claims, to
							 | 
						|
								make, use, sell, offer for sale, import and otherwise run, modify and
							 | 
						|
								propagate the contents of its contributor version.
							 | 
						|
								
							 | 
						|
								  In the following three paragraphs, a "patent license" is any express
							 | 
						|
								agreement or commitment, however denominated, not to enforce a patent
							 | 
						|
								(such as an express permission to practice a patent or covenant not to
							 | 
						|
								sue for patent infringement).  To "grant" such a patent license to a
							 | 
						|
								party means to make such an agreement or commitment not to enforce a
							 | 
						|
								patent against the party.
							 | 
						|
								
							 | 
						|
								  If you convey a covered work, knowingly relying on a patent license,
							 | 
						|
								and the Corresponding Source of the work is not available for anyone
							 | 
						|
								to copy, free of charge and under the terms of this License, through a
							 | 
						|
								publicly available network server or other readily accessible means,
							 | 
						|
								then you must either (1) cause the Corresponding Source to be so
							 | 
						|
								available, or (2) arrange to deprive yourself of the benefit of the
							 | 
						|
								patent license for this particular work, or (3) arrange, in a manner
							 | 
						|
								consistent with the requirements of this License, to extend the patent
							 | 
						|
								license to downstream recipients.  "Knowingly relying" means you have
							 | 
						|
								actual knowledge that, but for the patent license, your conveying the
							 | 
						|
								covered work in a country, or your recipient's use of the covered work
							 | 
						|
								in a country, would infringe one or more identifiable patents in that
							 | 
						|
								country that you have reason to believe are valid.
							 | 
						|
								
							 | 
						|
								  If, pursuant to or in connection with a single transaction or
							 | 
						|
								arrangement, you convey, or propagate by procuring conveyance of, a
							 | 
						|
								covered work, and grant a patent license to some of the parties
							 | 
						|
								receiving the covered work authorizing them to use, propagate, modify
							 | 
						|
								or convey a specific copy of the covered work, then the patent license
							 | 
						|
								you grant is automatically extended to all recipients of the covered
							 | 
						|
								work and works based on it.
							 | 
						|
								
							 | 
						|
								  A patent license is "discriminatory" if it does not include within
							 | 
						|
								the scope of its coverage, prohibits the exercise of, or is
							 | 
						|
								conditioned on the non-exercise of one or more of the rights that are
							 | 
						|
								specifically granted under this License.  You may not convey a covered
							 | 
						|
								work if you are a party to an arrangement with a third party that is
							 | 
						|
								in the business of distributing software, under which you make payment
							 | 
						|
								to the third party based on the extent of your activity of conveying
							 | 
						|
								the work, and under which the third party grants, to any of the
							 | 
						|
								parties who would receive the covered work from you, a discriminatory
							 | 
						|
								patent license (a) in connection with copies of the covered work
							 | 
						|
								conveyed by you (or copies made from those copies), or (b) primarily
							 | 
						|
								for and in connection with specific products or compilations that
							 | 
						|
								contain the covered work, unless you entered into that arrangement,
							 | 
						|
								or that patent license was granted, prior to 28 March 2007.
							 | 
						|
								
							 | 
						|
								  Nothing in this License shall be construed as excluding or limiting
							 | 
						|
								any implied license or other defenses to infringement that may
							 | 
						|
								otherwise be available to you under applicable patent law.
							 | 
						|
								
							 | 
						|
								  12. No Surrender of Others' Freedom.
							 | 
						|
								
							 | 
						|
								  If conditions are imposed on you (whether by court order, agreement or
							 | 
						|
								otherwise) that contradict the conditions of this License, they do not
							 | 
						|
								excuse you from the conditions of this License.  If you cannot convey a
							 | 
						|
								covered work so as to satisfy simultaneously your obligations under this
							 | 
						|
								License and any other pertinent obligations, then as a consequence you may
							 | 
						|
								not convey it at all.  For example, if you agree to terms that obligate you
							 | 
						|
								to collect a royalty for further conveying from those to whom you convey
							 | 
						|
								the Program, the only way you could satisfy both those terms and this
							 | 
						|
								License would be to refrain entirely from conveying the Program.
							 | 
						|
								
							 | 
						|
								  13. Use with the GNU Affero General Public License.
							 | 
						|
								
							 | 
						|
								  Notwithstanding any other provision of this License, you have
							 | 
						|
								permission to link or combine any covered work with a work licensed
							 | 
						|
								under version 3 of the GNU Affero General Public License into a single
							 | 
						|
								combined work, and to convey the resulting work.  The terms of this
							 | 
						|
								License will continue to apply to the part which is the covered work,
							 | 
						|
								but the special requirements of the GNU Affero General Public License,
							 | 
						|
								section 13, concerning interaction through a network will apply to the
							 | 
						|
								combination as such.
							 | 
						|
								
							 | 
						|
								  14. Revised Versions of this License.
							 | 
						|
								
							 | 
						|
								  The Free Software Foundation may publish revised and/or new versions of
							 | 
						|
								the GNU General Public License from time to time.  Such new versions will
							 | 
						|
								be similar in spirit to the present version, but may differ in detail to
							 | 
						|
								address new problems or concerns.
							 | 
						|
								
							 | 
						|
								  Each version is given a distinguishing version number.  If the
							 | 
						|
								Program specifies that a certain numbered version of the GNU General
							 | 
						|
								Public License "or any later version" applies to it, you have the
							 | 
						|
								option of following the terms and conditions either of that numbered
							 | 
						|
								version or of any later version published by the Free Software
							 | 
						|
								Foundation.  If the Program does not specify a version number of the
							 | 
						|
								GNU General Public License, you may choose any version ever published
							 | 
						|
								by the Free Software Foundation.
							 | 
						|
								
							 | 
						|
								  If the Program specifies that a proxy can decide which future
							 | 
						|
								versions of the GNU General Public License can be used, that proxy's
							 | 
						|
								public statement of acceptance of a version permanently authorizes you
							 | 
						|
								to choose that version for the Program.
							 | 
						|
								
							 | 
						|
								  Later license versions may give you additional or different
							 | 
						|
								permissions.  However, no additional obligations are imposed on any
							 | 
						|
								author or copyright holder as a result of your choosing to follow a
							 | 
						|
								later version.
							 | 
						|
								
							 | 
						|
								  15. Disclaimer of Warranty.
							 | 
						|
								
							 | 
						|
								  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
							 | 
						|
								APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
							 | 
						|
								HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
							 | 
						|
								OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
							 | 
						|
								THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
							 | 
						|
								PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
							 | 
						|
								IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
							 | 
						|
								ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
							 | 
						|
								
							 | 
						|
								  16. Limitation of Liability.
							 | 
						|
								
							 | 
						|
								  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
							 | 
						|
								WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
							 | 
						|
								THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
							 | 
						|
								GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
							 | 
						|
								USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
							 | 
						|
								DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
							 | 
						|
								PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
							 | 
						|
								EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
							 | 
						|
								SUCH DAMAGES.
							 | 
						|
								
							 | 
						|
								  17. Interpretation of Sections 15 and 16.
							 | 
						|
								
							 | 
						|
								  If the disclaimer of warranty and limitation of liability provided
							 | 
						|
								above cannot be given local legal effect according to their terms,
							 | 
						|
								reviewing courts shall apply local law that most closely approximates
							 | 
						|
								an absolute waiver of all civil liability in connection with the
							 | 
						|
								Program, unless a warranty or assumption of liability accompanies a
							 | 
						|
								copy of the Program in return for a fee.
							 | 
						|
								
							 | 
						|
								                     END OF TERMS AND CONDITIONS
							 | 
						|
								
							 | 
						|
								            How to Apply These Terms to Your New Programs
							 | 
						|
								
							 | 
						|
								  If you develop a new program, and you want it to be of the greatest
							 | 
						|
								possible use to the public, the best way to achieve this is to make it
							 | 
						|
								free software which everyone can redistribute and change under these terms.
							 | 
						|
								
							 | 
						|
								  To do so, attach the following notices to the program.  It is safest
							 | 
						|
								to attach them to the start of each source file to most effectively
							 | 
						|
								state the exclusion of warranty; and each file should have at least
							 | 
						|
								the "copyright" line and a pointer to where the full notice is found.
							 | 
						|
								
							 | 
						|
								    <one line to give the program's name and a brief idea of what it does.>
							 | 
						|
								    Copyright (C) <year>  <name of author>
							 | 
						|
								
							 | 
						|
								    This program is free software: you can redistribute it and/or modify
							 |

						|
								    (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.

								  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
