+>                     GNU GENERAL PUBLIC LICENSE
+>                        Version 3, 29 June 2007
+> 
+>  Copyright (C) 2007 Free Software Foundation, Inc. 
+>  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
