-<nowiki>                    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>.
