/* 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
*
* How to Apply These Terms to Your New Programs
*
* If you develop a new program, and you want it to be of the greatest
* possible use to the public, the best way to achieve this is to make it
* free software which everyone can redistribute and change under these terms.
*
* To do so, attach the following notices to the program. It is safest
* to attach them to the start of each source file to most effectively
* state the exclusion of warranty; and each file should have at least
* the "copyright" line and a pointer to where the full notice is found.
*
* <one line to give the program's name and a brief idea of what it does.>
* Copyright (C) <year> <name of author>
*
* This program is free software: you can redistribute it and/or modify
* it under the terms of the GNU General Public License as published by
* the Free Software Foundation, either version 3 of the License, or
* (at your option) any later version.
*
* This program is distributed in the hope that it will be useful,
* but WITHOUT ANY WARRANTY; without even the implied warranty of
* MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
* GNU General Public License for more details.
*
* You should have received a copy of the GNU General Public License
* along with this program. If not, see <http://www.gnu.org/licenses/>.
*
* Also add information on how to contact you by electronic and paper mail.
*
* If the program does terminal interaction, make it output a short
* notice like this when it starts in an interactive mode:
*
* <program> Copyright (C) <year> <name of author>
* This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
* This is free software, and you are welcome to redistribute it
* under certain conditions; type `show c' for details.
*
* The hypothetical commands `show w' and `show c' should show the appropriate
* parts of the General Public License. Of course, your program's commands
* might be different; for a GUI interface, you would use an "about box".
*
* You should also get your employer (if you work as a programmer) or school,
* if any, to sign a "copyright disclaimer" for the program, if necessary.
* For more information on this, and how to apply and follow the GNU GPL, see
* <http://www.gnu.org/licenses/>.
*
* The GNU General Public License does not permit incorporating your program
* into proprietary programs. If your program is a subroutine library, you
* may consider it more useful to permit linking proprietary applications with
* the library. If this is what you want to do, use the GNU Lesser General
* Public License instead of this License. But first, please read
* <http://www.gnu.org/philosophy/why-not-lgpl.html>.
