   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>.
