## GNU GENERAL PUBLIC LICENSE
## Version 3, 29 June 2007
##
## Copyright (C) 2007 Free Software Foundation, Inc. <http://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
