                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:
                
                {project}  Copyright (C) {year}  {fullname}
                This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
                This is free software, and you are welcome to redistribute it
                under certain conditions; type `show c' for details.
                
                The hypothetical commands `show w' and `show c' should show the appropriate
                parts of the General Public License.  Of course, your program's commands
                might be different; for a GUI interface, you would use an "about box".
                
                You should also get your employer (if you work as a programmer) or school,
                if any, to sign a "copyright disclaimer" for the program, if necessary.

                The GNU General Public License does not permit incorporating your program
                into proprietary programs.  If your program is a subroutine library, you
                may consider it more useful to permit linking proprietary applications with
                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
