Appendix N Copying

                          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>.
                        GNU LESSER 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.
     
     
       This version of the GNU Lesser General Public License incorporates
     the terms and conditions of version 3 of the GNU General Public
     License, supplemented by the additional permissions listed below.
     
       0. Additional Definitions.
     
       As used herein, "this License" refers to version 3 of the GNU Lesser
     General Public License, and the "GNU GPL" refers to version 3 of the GNU
     General Public License.
     
       "The Library" refers to a covered work governed by this License,
     other than an Application or a Combined Work as defined below.
     
       An "Application" is any work that makes use of an interface provided
     by the Library, but which is not otherwise based on the Library.
     Defining a subclass of a class defined by the Library is deemed a mode
     of using an interface provided by the Library.
     
       A "Combined Work" is a work produced by combining or linking an
     Application with the Library.  The particular version of the Library
     with which the Combined Work was made is also called the "Linked
     Version".
     
       The "Minimal Corresponding Source" for a Combined Work means the
     Corresponding Source for the Combined Work, excluding any source code
     for portions of the Combined Work that, considered in isolation, are
     based on the Application, and not on the Linked Version.
     
       The "Corresponding Application Code" for a Combined Work means the
     object code and/or source code for the Application, including any data
     and utility programs needed for reproducing the Combined Work from the
     Application, but excluding the System Libraries of the Combined Work.
     
       1. Exception to Section 3 of the GNU GPL.
     
       You may convey a covered work under sections 3 and 4 of this License
     without being bound by section 3 of the GNU GPL.
     
       2. Conveying Modified Versions.
     
       If you modify a copy of the Library, and, in your modifications, a
     facility refers to a function or data to be supplied by an Application
     that uses the facility (other than as an argument passed when the
     facility is invoked), then you may convey a copy of the modified
     version:
     
        a) under this License, provided that you make a good faith effort to
        ensure that, in the event an Application does not supply the
        function or data, the facility still operates, and performs
        whatever part of its purpose remains meaningful, or
     
        b) under the GNU GPL, with none of the additional permissions of
        this License applicable to that copy.
     
       3. Object Code Incorporating Material from Library Header Files.
     
       The object code form of an Application may incorporate material from
     a header file that is part of the Library.  You may convey such object
     code under terms of your choice, provided that, if the incorporated
     material is not limited to numerical parameters, data structure
     layouts and accessors, or small macros, inline functions and templates
     (ten or fewer lines in length), you do both of the following:
     
        a) Give prominent notice with each copy of the object code that the
        Library is used in it and that the Library and its use are
        covered by this License.
     
        b) Accompany the object code with a copy of the GNU GPL and this license
        document.
     
       4. Combined Works.
     
       You may convey a Combined Work under terms of your choice that,
     taken together, effectively do not restrict modification of the
     portions of the Library contained in the Combined Work and reverse
     engineering for debugging such modifications, if you also do each of
     the following:
     
        a) Give prominent notice with each copy of the Combined Work that
        the Library is used in it and that the Library and its use are
        covered by this License.
     
        b) Accompany the Combined Work with a copy of the GNU GPL and this license
        document.
     
        c) For a Combined Work that displays copyright notices during
        execution, include the copyright notice for the Library among
        these notices, as well as a reference directing the user to the
        copies of the GNU GPL and this license document.
     
        d) Do one of the following:
     
            0) Convey the Minimal Corresponding Source under the terms of this
            License, and the Corresponding Application Code in a form
            suitable for, and under terms that permit, the user to
            recombine or relink the Application with a modified version of
            the Linked Version to produce a modified Combined Work, in the
            manner specified by section 6 of the GNU GPL for conveying
            Corresponding Source.
     
            1) Use a suitable shared library mechanism for linking with the
            Library.  A suitable mechanism is one that (a) uses at run time
            a copy of the Library already present on the user's computer
            system, and (b) will operate properly with a modified version
            of the Library that is interface-compatible with the Linked
            Version.
     
        e) Provide Installation Information, but only if you would otherwise
        be required to provide such information under section 6 of the
        GNU GPL, and only to the extent that such information is
        necessary to install and execute a modified version of the
        Combined Work produced by recombining or relinking the
        Application with a modified version of the Linked Version. (If
        you use option 4d0, the Installation Information must accompany
        the Minimal Corresponding Source and Corresponding Application
        Code. If you use option 4d1, you must provide the Installation
        Information in the manner specified by section 6 of the GNU GPL
        for conveying Corresponding Source.)
     
       5. Combined Libraries.
     
       You may place library facilities that are a work based on the
     Library side by side in a single library together with other library
     facilities that are not Applications and are not covered by this
     License, and convey such a combined library under terms of your
     choice, if you do both of the following:
     
        a) Accompany the combined library with a copy of the same work based
        on the Library, uncombined with any other library facilities,
        conveyed under the terms of this License.
     
        b) Give prominent notice with the combined library that part of it
        is a work based on the Library, and explaining where to find the
        accompanying uncombined form of the same work.
     
       6. Revised Versions of the GNU Lesser General Public License.
     
       The Free Software Foundation may publish revised and/or new versions
     of the GNU Lesser 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
     Library as you received it specifies that a certain numbered version
     of the GNU Lesser General Public License "or any later version"
     applies to it, you have the option of following the terms and
     conditions either of that published version or of any later version
     published by the Free Software Foundation. If the Library as you
     received it does not specify a version number of the GNU Lesser
     General Public License, you may choose any version of the GNU Lesser
     General Public License ever published by the Free Software Foundation.
     
       If the Library as you received it specifies that a proxy can decide
     whether future versions of the GNU Lesser General Public License shall
     apply, that proxy's public statement of acceptance of any version is
     permanent authorization for you to choose that version for the
     Library.
