+GNU GENERAL PUBLIC LICENSE Version 3, 29 June 2007
+
+Copyright © 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
