       <h3 style="text-align: center;">GNU GENERAL PUBLIC LICENSE</h3>
       <p style="text-align: center;">Version 3, 29 June 2007</p>
       <p>Copyright © 2007 Free Software Foundation, Inc.
        &lt;<a href="http://fsf.org/">http://fsf.org/</a>&gt;</p><p>
        Everyone is permitted to copy and distribute verbatim copies
        of this license document, but changing it is not allowed.</p>
       <h3><a name="preamble"></a>Preamble</h3>
       <p>The GNU General Public License is a free, copyleft license for
       software and other kinds of works.</p>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <p>The precise terms and conditions for copying, distribution and
       modification follow.</p>
       <h3><a name="terms"></a>TERMS AND CONDITIONS</h3>
       <h4><a name="section0"></a>0. Definitions.</h4>
       <p>“This License” refers to version 3 of the GNU General Public License.</p>
       <p>“Copyright” also means copyright-like laws that apply to other kinds of
       works, such as semiconductor masks.</p>
       <p>“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.</p>
       <p>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.</p>
       <p>A “covered work” means either the unmodified Program or a work based
       on the Program.</p>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <h4><a name="section1"></a>1. Source Code.</h4>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <p>The Corresponding Source need not include anything that users
       can regenerate automatically from other parts of the Corresponding
       Source.</p>
       <p>The Corresponding Source for a work in source code form is that
       same work.</p>
       <h4><a name="section2"></a>2. Basic Permissions.</h4>
       <p>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.</p>
       <p>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.</p>
       <p>Conveying under any other circumstances is permitted solely under
       the conditions stated below.  Sublicensing is not allowed; section 10
       makes it unnecessary.</p>
       <h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4>
       <p>No covered work shall be deemed part of an effective technological
       measure under any applicable law fulfilling obligations under article
 of the WIPO copyright treaty adopted on 20 December 1996, or
       similar laws prohibiting or restricting circumvention of such
       measures.</p>
       <p>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.</p>
       <h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4>
       <p>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.</p>
       <p>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.</p>
       <h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4>
       <p>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:</p>
       <ul>
       <li>a) The work must carry prominent notices stating that you modified
           it, and giving a relevant date.</li>
       <li>b) The work must carry prominent notices stating that it is
           released under this License and any conditions added under section
 .  This requirement modifies the requirement in section 4 to
           “keep intact all notices”.</li>
       <li>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.</li>
       <li>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.</li>
       </ul>
       <p>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.</p>
       <h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4>
       <p>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:</p>
       <ul>
       <li>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.</li>
       <li>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.</li>
       <li>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.</li>
       <li>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.</li>
       <li>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.</li>
       </ul>
       <p>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.</p>
       <p>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.</p>
       <p>“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.</p>
       <p>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).</p>
       <p>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.</p>
       <p>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.</p>
       <h4><a name="section7"></a>7. Additional Terms.</h4>
       <p>“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.</p>
       <p>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.</p>
       <p>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:</p>
       <ul>
       <li>a) Disclaiming warranty or limiting liability differently from the
           terms of sections 15 and 16 of this License; or</li>
       <li>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</li>
       <li>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</li>
       <li>d) Limiting the use for publicity purposes of names of licensors or
           authors of the material; or</li>
       <li>e) Declining to grant rights under trademark law for use of some
           trade names, trademarks, or service marks; or</li>
       <li>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.</li>
       </ul>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <h4><a name="section8"></a>8. Termination.</h4>
       <p>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).</p>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4>
       <p>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.</p>
       <h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <h4><a name="section11"></a>11. Patents.</h4>
       <p>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”.</p>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4>
       <p>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.</p>
       <h4><a name="section13"></a>13. Use with the GNU Affero General Public License.</h4>
       <p>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.</p>
       <h4><a name="section14"></a>14. Revised Versions of this License.</h4>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <p>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.</p>
       <h4><a name="section15"></a>15. Disclaimer of Warranty.</h4>
       <p>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.</p>
       <h4><a name="section16"></a>16. Limitation of Liability.</h4>
       <p>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.</p>
       <h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4>
       <p>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.</p>
       <p>END OF TERMS AND CONDITIONS</p>
       <h3><a name="howto"></a>How to Apply These Terms to Your New Programs</h3>
       <p>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.</p>
       <p>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.</p>
       <pre>    &lt;one line to give the program's name and a brief idea of what it does.&gt;
           Copyright (C) &lt;year&gt;  &lt;name of author&gt;
           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 &lt;http://www.gnu.org/licenses/&gt;.
       </pre>
       <p>Also add information on how to contact you by electronic and paper mail.</p>
       <p>If the program does terminal interaction, make it output a short
       notice like this when it starts in an interactive mode:</p>
       <pre>    &lt;program&gt;  Copyright (C) &lt;year&gt;  &lt;name of author&gt;
           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.
       </pre>
       <p>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”.</p>
       <p>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.

       <p>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
