     14                    GNU GENERAL PUBLIC LICENSE 
     15                       Version 3, 29 June 2007 
     16 
     17 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> 
     18 Everyone is permitted to copy and distribute verbatim copies 
     19 of this license document, but changing it is not allowed. 
     20 
     21                            Preamble 
     22 
     23  The GNU General Public License is a free, copyleft license for 
     24software and other kinds of works. 
     25 
     26  The licenses for most software and other practical works are designed 
     27to take away your freedom to share and change the works.  By contrast, 
     28the GNU General Public License is intended to guarantee your freedom to 
     29share and change all versions of a program--to make sure it remains free 
     30software for all its users.  We, the Free Software Foundation, use the 
     31GNU General Public License for most of our software; it applies also to 
     32any other work released this way by its authors.  You can apply it to 
     33your programs, too. 
     34 
     35  When we speak of free software, we are referring to freedom, not 
     36price.  Our General Public Licenses are designed to make sure that you 
     37have the freedom to distribute copies of free software (and charge for 
     38them if you wish), that you receive source code or can get it if you 
     39want it, that you can change the software or use pieces of it in new 
     40free programs, and that you know you can do these things. 
     41 
     42  To protect your rights, we need to prevent others from denying you 
     43these rights or asking you to surrender the rights.  Therefore, you have 
     44certain responsibilities if you distribute copies of the software, or if 
     45you modify it: responsibilities to respect the freedom of others. 
     46 
     47  For example, if you distribute copies of such a program, whether 
     48gratis or for a fee, you must pass on to the recipients the same 
     49freedoms that you received.  You must make sure that they, too, receive 
     50or can get the source code.  And you must show them these terms so they 
     51know their rights. 
     52 
     53  Developers that use the GNU GPL protect your rights with two steps: 
     54(1) assert copyright on the software, and (2) offer you this License 
     55giving you legal permission to copy, distribute and/or modify it. 
     56 
     57  For the developers' and authors' protection, the GPL clearly explains 
     58that there is no warranty for this free software.  For both users' and 
     59authors' sake, the GPL requires that modified versions be marked as 
     60changed, so that their problems will not be attributed erroneously to 
     61authors of previous versions. 
     62 
     63  Some devices are designed to deny users access to install or run 
     64modified versions of the software inside them, although the manufacturer 
     65can do so.  This is fundamentally incompatible with the aim of 
     66protecting users' freedom to change the software.  The systematic 
     67pattern of such abuse occurs in the area of products for individuals to 
     68use, which is precisely where it is most unacceptable.  Therefore, we 
     69have designed this version of the GPL to prohibit the practice for those 
     70products.  If such problems arise substantially in other domains, we 
     71stand ready to extend this provision to those domains in future versions 
     72of the GPL, as needed to protect the freedom of users. 
     73 
     74  Finally, every program is threatened constantly by software patents. 
     75States should not allow patents to restrict development and use of 
     76software on general-purpose computers, but in those that do, we wish to 
     77avoid the special danger that patents applied to a free program could 
     78make it effectively proprietary.  To prevent this, the GPL assures that 
     79patents cannot be used to render the program non-free. 
     80 
     81  The precise terms and conditions for copying, distribution and 
     82modification follow. 
     83 
     84                       TERMS AND CONDITIONS 
     85 
     86  0. Definitions. 
     87 
     88  "This License" refers to version 3 of the GNU General Public License. 
     89 
     90  "Copyright" also means copyright-like laws that apply to other kinds of 
     91works, such as semiconductor masks. 
     92 
     93  "The Program" refers to any copyrightable work licensed under this 
     94License.  Each licensee is addressed as "you".  "Licensees" and 
     95"recipients" may be individuals or organizations. 
     96 
     97  To "modify" a work means to copy from or adapt all or part of the work 
     98in a fashion requiring copyright permission, other than the making of an 
     99exact copy.  The resulting work is called a "modified version" of the 
     100earlier work or a work "based on" the earlier work. 
     101 
     102  A "covered work" means either the unmodified Program or a work based 
     103on the Program. 
     104 
     105  To "propagate" a work means to do anything with it that, without 
     106permission, would make you directly or secondarily liable for 
     107infringement under applicable copyright law, except executing it on a 
     108computer or modifying a private copy.  Propagation includes copying, 
     109distribution (with or without modification), making available to the 
     110public, and in some countries other activities as well. 
     111 
     112  To "convey" a work means any kind of propagation that enables other 
     113parties to make or receive copies.  Mere interaction with a user through 
     114a computer network, with no transfer of a copy, is not conveying. 
     115 
     116  An interactive user interface displays "Appropriate Legal Notices" 
     117to the extent that it includes a convenient and prominently visible 
     118feature that (1) displays an appropriate copyright notice, and (2) 
     119tells the user that there is no warranty for the work (except to the 
     120extent that warranties are provided), that licensees may convey the 
     121work under this License, and how to view a copy of this License.  If 
     122the interface presents a list of user commands or options, such as a 
     123menu, a prominent item in the list meets this criterion. 
     124 
     125  1. Source Code. 
     126 
     127  The "source code" for a work means the preferred form of the work 
     128for making modifications to it.  "Object code" means any non-source 
     129form of a work. 
     130 
     131  A "Standard Interface" means an interface that either is an official 
     132standard defined by a recognized standards body, or, in the case of 
     133interfaces specified for a particular programming language, one that 
     134is widely used among developers working in that language. 
     135 
     136  The "System Libraries" of an executable work include anything, other 
     137than the work as a whole, that (a) is included in the normal form of 
     138packaging a Major Component, but which is not part of that Major 
     139Component, and (b) serves only to enable use of the work with that 
     140Major Component, or to implement a Standard Interface for which an 
     141implementation is available to the public in source code form.  A 
     142"Major Component", in this context, means a major essential component 
     143(kernel, window system, and so on) of the specific operating system 
     144(if any) on which the executable work runs, or a compiler used to 
     145produce the work, or an object code interpreter used to run it. 
     146 
     147  The "Corresponding Source" for a work in object code form means all 
     148the source code needed to generate, install, and (for an executable 
     149work) run the object code and to modify the work, including scripts to 
     150control those activities.  However, it does not include the work's 
     151System Libraries, or general-purpose tools or generally available free 
     152programs which are used unmodified in performing those activities but 
     153which are not part of the work.  For example, Corresponding Source 
     154includes interface definition files associated with source files for 
     155the work, and the source code for shared libraries and dynamically 
     156linked subprograms that the work is specifically designed to require, 
     157such as by intimate data communication or control flow between those 
     158subprograms and other parts of the work. 
     159 
     160  The Corresponding Source need not include anything that users 
     161can regenerate automatically from other parts of the Corresponding 
     162Source. 
     163 
     164  The Corresponding Source for a work in source code form is that 
     165same work. 
     166 
     167  2. Basic Permissions. 
     168 
     169  All rights granted under this License are granted for the term of 
     170copyright on the Program, and are irrevocable provided the stated 
     171conditions are met.  This License explicitly affirms your unlimited 
     172permission to run the unmodified Program.  The output from running a 
     173covered work is covered by this License only if the output, given its 
     174content, constitutes a covered work.  This License acknowledges your 
     175rights of fair use or other equivalent, as provided by copyright law. 
     176 
     177  You may make, run and propagate covered works that you do not 
     178convey, without conditions so long as your license otherwise remains 
     179in force.  You may convey covered works to others for the sole purpose 
     180of having them make modifications exclusively for you, or provide you 
     181with facilities for running those works, provided that you comply with 
     182the terms of this License in conveying all material for which you do 
     183not control copyright.  Those thus making or running the covered works 
     184for you must do so exclusively on your behalf, under your direction 
     185and control, on terms that prohibit them from making any copies of 
     186your copyrighted material outside their relationship with you. 
     187 
     188  Conveying under any other circumstances is permitted solely under 
     189the conditions stated below.  Sublicensing is not allowed; section 10 
     190makes it unnecessary. 
     191 
     192  3. Protecting Users' Legal Rights From Anti-Circumvention Law. 
     193 
     194  No covered work shall be deemed part of an effective technological 
     195measure under any applicable law fulfilling obligations under article 
     19611 of the WIPO copyright treaty adopted on 20 December 1996, or 
     197similar laws prohibiting or restricting circumvention of such 
     198measures. 
     199 
     200  When you convey a covered work, you waive any legal power to forbid 
     201circumvention of technological measures to the extent such circumvention 
     202is effected by exercising rights under this License with respect to 
     203the covered work, and you disclaim any intention to limit operation or 
     204modification of the work as a means of enforcing, against the work's 
     205users, your or third parties' legal rights to forbid circumvention of 
     206technological measures. 
     207 
     208  4. Conveying Verbatim Copies. 
     209 
     210  You may convey verbatim copies of the Program's source code as you 
     211receive it, in any medium, provided that you conspicuously and 
     212appropriately publish on each copy an appropriate copyright notice; 
     213keep intact all notices stating that this License and any 
     214non-permissive terms added in accord with section 7 apply to the code; 
     215keep intact all notices of the absence of any warranty; and give all 
     216recipients a copy of this License along with the Program. 
     217 
     218  You may charge any price or no price for each copy that you convey, 
     219and you may offer support or warranty protection for a fee. 
     220 
     221  5. Conveying Modified Source Versions. 
     222 
     223  You may convey a work based on the Program, or the modifications to 
     224produce it from the Program, in the form of source code under the 
     225terms of section 4, provided that you also meet all of these conditions: 
     226 
     227    a) The work must carry prominent notices stating that you modified 
     228    it, and giving a relevant date. 
     229 
     230    b) The work must carry prominent notices stating that it is 
     231    released under this License and any conditions added under section 
     232    7.  This requirement modifies the requirement in section 4 to 
     233    "keep intact all notices". 
     234 
     235    c) You must license the entire work, as a whole, under this 
     236    License to anyone who comes into possession of a copy.  This 
     237    License will therefore apply, along with any applicable section 7 
     238    additional terms, to the whole of the work, and all its parts, 
     239    regardless of how they are packaged.  This License gives no 
     240    permission to license the work in any other way, but it does not 
     241    invalidate such permission if you have separately received it. 
     242 
     243    d) If the work has interactive user interfaces, each must display 
     244    Appropriate Legal Notices; however, if the Program has interactive 
     245    interfaces that do not display Appropriate Legal Notices, your 
     246    work need not make them do so. 
     247 
     248  A compilation of a covered work with other separate and independent 
     249works, which are not by their nature extensions of the covered work, 
     250and which are not combined with it such as to form a larger program, 
     251in or on a volume of a storage or distribution medium, is called an 
     252"aggregate" if the compilation and its resulting copyright are not 
     253used to limit the access or legal rights of the compilation's users 
     254beyond what the individual works permit.  Inclusion of a covered work 
     255in an aggregate does not cause this License to apply to the other 
     256parts of the aggregate. 
     257 
     258  6. Conveying Non-Source Forms. 
     259 
     260  You may convey a covered work in object code form under the terms 
     261of sections 4 and 5, provided that you also convey the 
     262machine-readable Corresponding Source under the terms of this License, 
     263in one of these ways: 
     264 
     265    a) Convey the object code in, or embodied in, a physical product 
     266    (including a physical distribution medium), accompanied by the 
     267    Corresponding Source fixed on a durable physical medium 
     268    customarily used for software interchange. 
     269 
     270    b) Convey the object code in, or embodied in, a physical product 
     271    (including a physical distribution medium), accompanied by a 
     272    written offer, valid for at least three years and valid for as 
     273    long as you offer spare parts or customer support for that product 
     274    model, to give anyone who possesses the object code either (1) a 
     275    copy of the Corresponding Source for all the software in the 
     276    product that is covered by this License, on a durable physical 
     277    medium customarily used for software interchange, for a price no 
     278    more than your reasonable cost of physically performing this 
     279    conveying of source, or (2) access to copy the 
     280    Corresponding Source from a network server at no charge. 
     281 
     282    c) Convey individual copies of the object code with a copy of the 
     283    written offer to provide the Corresponding Source.  This 
     284    alternative is allowed only occasionally and noncommercially, and 
     285    only if you received the object code with such an offer, in accord 
     286    with subsection 6b. 
     287 
     288    d) Convey the object code by offering access from a designated 
     289    place (gratis or for a charge), and offer equivalent access to the 
     290    Corresponding Source in the same way through the same place at no 
     291    further charge.  You need not require recipients to copy the 
     292    Corresponding Source along with the object code.  If the place to 
     293    copy the object code is a network server, the Corresponding Source 
     294    may be on a different server (operated by you or a third party) 
     295    that supports equivalent copying facilities, provided you maintain 
     296    clear directions next to the object code saying where to find the 
     297    Corresponding Source.  Regardless of what server hosts the 
     298    Corresponding Source, you remain obligated to ensure that it is 
     299    available for as long as needed to satisfy these requirements. 
     300 
     301    e) Convey the object code using peer-to-peer transmission, provided 
     302    you inform other peers where the object code and Corresponding 
     303    Source of the work are being offered to the general public at no 
     304    charge under subsection 6d. 
     305 
     306  A separable portion of the object code, whose source code is excluded 
     307from the Corresponding Source as a System Library, need not be 
     308included in conveying the object code work. 
     309 
     310  A "User Product" is either (1) a "consumer product", which means any 
     311tangible personal property which is normally used for personal, family, 
     312or household purposes, or (2) anything designed or sold for incorporation 
     313into a dwelling.  In determining whether a product is a consumer product, 
     314doubtful cases shall be resolved in favor of coverage.  For a particular 
     315product received by a particular user, "normally used" refers to a 
     316typical or common use of that class of product, regardless of the status 
     317of the particular user or of the way in which the particular user 
     318actually uses, or expects or is expected to use, the product.  A product 
     319is a consumer product regardless of whether the product has substantial 
     320commercial, industrial or non-consumer uses, unless such uses represent 
     321the only significant mode of use of the product. 
     322 
     323  "Installation Information" for a User Product means any methods, 
     324procedures, authorization keys, or other information required to install 
     325and execute modified versions of a covered work in that User Product from 
     326a modified version of its Corresponding Source.  The information must 
     327suffice to ensure that the continued functioning of the modified object 
     328code is in no case prevented or interfered with solely because 
     329modification has been made. 
     330 
     331  If you convey an object code work under this section in, or with, or 
     332specifically for use in, a User Product, and the conveying occurs as 
     333part of a transaction in which the right of possession and use of the 
     334User Product is transferred to the recipient in perpetuity or for a 
     335fixed term (regardless of how the transaction is characterized), the 
     336Corresponding Source conveyed under this section must be accompanied 
     337by the Installation Information.  But this requirement does not apply 
     338if neither you nor any third party retains the ability to install 
     339modified object code on the User Product (for example, the work has 
     340been installed in ROM). 
     341 
     342  The requirement to provide Installation Information does not include a 
     343requirement to continue to provide support service, warranty, or updates 
     344for a work that has been modified or installed by the recipient, or for 
     345the User Product in which it has been modified or installed.  Access to a 
     346network may be denied when the modification itself materially and 
     347adversely affects the operation of the network or violates the rules and 
     348protocols for communication across the network. 
     349 
     350  Corresponding Source conveyed, and Installation Information provided, 
     351in accord with this section must be in a format that is publicly 
     352documented (and with an implementation available to the public in 
     353source code form), and must require no special password or key for 
     354unpacking, reading or copying. 
     355 
     356  7. Additional Terms. 
     357 
     358  "Additional permissions" are terms that supplement the terms of this 
     359License by making exceptions from one or more of its conditions. 
     360Additional permissions that are applicable to the entire Program shall 
     361be treated as though they were included in this License, to the extent 
     362that they are valid under applicable law.  If additional permissions 
     363apply only to part of the Program, that part may be used separately 
     364under those permissions, but the entire Program remains governed by 
     365this License without regard to the additional permissions. 
     366 
     367  When you convey a copy of a covered work, you may at your option 
     368remove any additional permissions from that copy, or from any part of 
     369it.  (Additional permissions may be written to require their own 
     370removal in certain cases when you modify the work.)  You may place 
     371additional permissions on material, added by you to a covered work, 
     372for which you have or can give appropriate copyright permission. 
     373 
     374  Notwithstanding any other provision of this License, for material you 
     375add to a covered work, you may (if authorized by the copyright holders of 
     376that material) supplement the terms of this License with terms: 
     377 
     378    a) Disclaiming warranty or limiting liability differently from the 
     379    terms of sections 15 and 16 of this License; or 
     380 
     381    b) Requiring preservation of specified reasonable legal notices or 
     382    author attributions in that material or in the Appropriate Legal 
     383    Notices displayed by works containing it; or 
     384 
     385    c) Prohibiting misrepresentation of the origin of that material, or 
     386    requiring that modified versions of such material be marked in 
     387    reasonable ways as different from the original version; or 
     388 
     389    d) Limiting the use for publicity purposes of names of licensors or 
     390    authors of the material; or 
     391 
     392    e) Declining to grant rights under trademark law for use of some 
     393    trade names, trademarks, or service marks; or 
     394 
     395    f) Requiring indemnification of licensors and authors of that 
     396    material by anyone who conveys the material (or modified versions of 
     397    it) with contractual assumptions of liability to the recipient, for 
     398    any liability that these contractual assumptions directly impose on 
     399    those licensors and authors. 
     400 
     401  All other non-permissive additional terms are considered "further 
     402restrictions" within the meaning of section 10.  If the Program as you 
     403received it, or any part of it, contains a notice stating that it is 
     404governed by this License along with a term that is a further 
     405restriction, you may remove that term.  If a license document contains 
     406a further restriction but permits relicensing or conveying under this 
     407License, you may add to a covered work material governed by the terms 
     408of that license document, provided that the further restriction does 
     409not survive such relicensing or conveying. 
     410 
     411  If you add terms to a covered work in accord with this section, you 
     412must place, in the relevant source files, a statement of the 
     413additional terms that apply to those files, or a notice indicating 
     414where to find the applicable terms. 
     415 
     416  Additional terms, permissive or non-permissive, may be stated in the 
     417form of a separately written license, or stated as exceptions; 
     418the above requirements apply either way. 
     419 
     420  8. Termination. 
     421 
     422  You may not propagate or modify a covered work except as expressly 
     423provided under this License.  Any attempt otherwise to propagate or 
     424modify it is void, and will automatically terminate your rights under 
     425this License (including any patent licenses granted under the third 
     426paragraph of section 11). 
     427 
     428  However, if you cease all violation of this License, then your 
     429license from a particular copyright holder is reinstated (a) 
     430provisionally, unless and until the copyright holder explicitly and 
     431finally terminates your license, and (b) permanently, if the copyright 
     432holder fails to notify you of the violation by some reasonable means 
     433prior to 60 days after the cessation. 
     434 
     435  Moreover, your license from a particular copyright holder is 
     436reinstated permanently if the copyright holder notifies you of the 
     437violation by some reasonable means, this is the first time you have 
     438received notice of violation of this License (for any work) from that 
     439copyright holder, and you cure the violation prior to 30 days after 
     440your receipt of the notice. 
     441 
     442  Termination of your rights under this section does not terminate the 
     443licenses of parties who have received copies or rights from you under 
     444this License.  If your rights have been terminated and not permanently 
     445reinstated, you do not qualify to receive new licenses for the same 
     446material under section 10. 
     447 
     448  9. Acceptance Not Required for Having Copies. 
     449 
     450  You are not required to accept this License in order to receive or 
     451run a copy of the Program.  Ancillary propagation of a covered work 
     452occurring solely as a consequence of using peer-to-peer transmission 
     453to receive a copy likewise does not require acceptance.  However, 
     454nothing other than this License grants you permission to propagate or 
     455modify any covered work.  These actions infringe copyright if you do 
     456not accept this License.  Therefore, by modifying or propagating a 
     457covered work, you indicate your acceptance of this License to do so. 
     458 
     459  10. Automatic Licensing of Downstream Recipients. 
     460 
     461  Each time you convey a covered work, the recipient automatically 
     462receives a license from the original licensors, to run, modify and 
     463propagate that work, subject to this License.  You are not responsible 
     464for enforcing compliance by third parties with this License. 
     465 
     466  An "entity transaction" is a transaction transferring control of an 
     467organization, or substantially all assets of one, or subdividing an 
     468organization, or merging organizations.  If propagation of a covered 
     469work results from an entity transaction, each party to that 
     470transaction who receives a copy of the work also receives whatever 
     471licenses to the work the party's predecessor in interest had or could 
     472give under the previous paragraph, plus a right to possession of the 
     473Corresponding Source of the work from the predecessor in interest, if 
     474the predecessor has it or can get it with reasonable efforts. 
     475 
     476  You may not impose any further restrictions on the exercise of the 
     477rights granted or affirmed under this License.  For example, you may 
     478not impose a license fee, royalty, or other charge for exercise of 
     479rights granted under this License, and you may not initiate litigation 
     480(including a cross-claim or counterclaim in a lawsuit) alleging that 
     481any patent claim is infringed by making, using, selling, offering for 
     482sale, or importing the Program or any portion of it. 
     483 
     484  11. Patents. 
     485 
     486  A "contributor" is a copyright holder who authorizes use under this 
     487License of the Program or a work on which the Program is based.  The 
     488work thus licensed is called the contributor's "contributor version". 
     489 
     490  A contributor's "essential patent claims" are all patent claims 
     491owned or controlled by the contributor, whether already acquired or 
     492hereafter acquired, that would be infringed by some manner, permitted 
     493by this License, of making, using, or selling its contributor version, 
     494but do not include claims that would be infringed only as a 
     495consequence of further modification of the contributor version.  For 
     496purposes of this definition, "control" includes the right to grant 
     497patent sublicenses in a manner consistent with the requirements of 
     498this License. 
     499 
     500  Each contributor grants you a non-exclusive, worldwide, royalty-free 
     501patent license under the contributor's essential patent claims, to 
     502make, use, sell, offer for sale, import and otherwise run, modify and 
     503propagate the contents of its contributor version. 
     504 
     505  In the following three paragraphs, a "patent license" is any express 
     506agreement or commitment, however denominated, not to enforce a patent 
     507(such as an express permission to practice a patent or covenant not to 
     508sue for patent infringement).  To "grant" such a patent license to a 
     509party means to make such an agreement or commitment not to enforce a 
     510patent against the party. 
     511 
     512  If you convey a covered work, knowingly relying on a patent license, 
     513and the Corresponding Source of the work is not available for anyone 
     514to copy, free of charge and under the terms of this License, through a 
     515publicly available network server or other readily accessible means, 
     516then you must either (1) cause the Corresponding Source to be so 
     517available, or (2) arrange to deprive yourself of the benefit of the 
     518patent license for this particular work, or (3) arrange, in a manner 
     519consistent with the requirements of this License, to extend the patent 
     520license to downstream recipients.  "Knowingly relying" means you have 
     521actual knowledge that, but for the patent license, your conveying the 
     522covered work in a country, or your recipient's use of the covered work 
     523in a country, would infringe one or more identifiable patents in that 
     524country that you have reason to believe are valid. 
     525 
     526  If, pursuant to or in connection with a single transaction or 
     527arrangement, you convey, or propagate by procuring conveyance of, a 
     528covered work, and grant a patent license to some of the parties 
     529receiving the covered work authorizing them to use, propagate, modify 
     530or convey a specific copy of the covered work, then the patent license 
     531you grant is automatically extended to all recipients of the covered 
     532work and works based on it. 
     533 
     534  A patent license is "discriminatory" if it does not include within 
     535the scope of its coverage, prohibits the exercise of, or is 
     536conditioned on the non-exercise of one or more of the rights that are 
     537specifically granted under this License.  You may not convey a covered 
     538work if you are a party to an arrangement with a third party that is 
     539in the business of distributing software, under which you make payment 
     540to the third party based on the extent of your activity of conveying 
     541the work, and under which the third party grants, to any of the 
     542parties who would receive the covered work from you, a discriminatory 
     543patent license (a) in connection with copies of the covered work 
     544conveyed by you (or copies made from those copies), or (b) primarily 
     545for and in connection with specific products or compilations that 
     546contain the covered work, unless you entered into that arrangement, 
     547or that patent license was granted, prior to 28 March 2007. 
     548 
     549  Nothing in this License shall be construed as excluding or limiting 
     550any implied license or other defenses to infringement that may 
     551otherwise be available to you under applicable patent law. 
     552 
     553  12. No Surrender of Others' Freedom. 
     554 
     555  If conditions are imposed on you (whether by court order, agreement or 
     556otherwise) that contradict the conditions of this License, they do not 
     557excuse you from the conditions of this License.  If you cannot convey a 
     558covered work so as to satisfy simultaneously your obligations under this 
     559License and any other pertinent obligations, then as a consequence you may 
     560not convey it at all.  For example, if you agree to terms that obligate you 
     561to collect a royalty for further conveying from those to whom you convey 
     562the Program, the only way you could satisfy both those terms and this 
     563License would be to refrain entirely from conveying the Program. 
     564 
     565  13. Use with the GNU Affero General Public License. 
     566 
     567  Notwithstanding any other provision of this License, you have 
     568permission to link or combine any covered work with a work licensed 
     569under version 3 of the GNU Affero General Public License into a single 
     570combined work, and to convey the resulting work.  The terms of this 
     571License will continue to apply to the part which is the covered work, 
     572but the special requirements of the GNU Affero General Public License, 
     573section 13, concerning interaction through a network will apply to the 
     574combination as such. 
     575 
     576  14. Revised Versions of this License. 
     577 
     578  The Free Software Foundation may publish revised and/or new versions of 
     579the GNU General Public License from time to time.  Such new versions will 
     580be similar in spirit to the present version, but may differ in detail to 
     581address new problems or concerns. 
     582 
     583  Each version is given a distinguishing version number.  If the 
     584Program specifies that a certain numbered version of the GNU General 
     585Public License "or any later version" applies to it, you have the 
     586option of following the terms and conditions either of that numbered 
     587version or of any later version published by the Free Software 
     588Foundation.  If the Program does not specify a version number of the 
     589GNU General Public License, you may choose any version ever published 
     590by the Free Software Foundation. 
     591 
     592  If the Program specifies that a proxy can decide which future 
     593versions of the GNU General Public License can be used, that proxy's 
     594public statement of acceptance of a version permanently authorizes you 
     595to choose that version for the Program. 
     596 
     597  Later license versions may give you additional or different 
     598permissions.  However, no additional obligations are imposed on any 
     599author or copyright holder as a result of your choosing to follow a 
     600later version. 
     601 
     602  15. Disclaimer of Warranty. 
     603 
     604  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 
     605APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 
     606HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 
     607OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 
     608THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 
     609PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 
     610IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 
     611ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 
     612 
     613  16. Limitation of Liability. 
     614 
     615  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 
     616WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 
     617THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 
     618GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 
     619USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 
     620DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 
     621PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 
     622EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 
     623SUCH DAMAGES. 
     624 
     625  17. Interpretation of Sections 15 and 16. 
     626 
     627  If the disclaimer of warranty and limitation of liability provided 
     628above cannot be given local legal effect according to their terms, 
     629reviewing courts shall apply local law that most closely approximates 
     630an absolute waiver of all civil liability in connection with the 
     631Program, unless a warranty or assumption of liability accompanies a 
     632copy of the Program in return for a fee. 
     633 
     634                     END OF TERMS AND CONDITIONS 
     635 
     636            How to Apply These Terms to Your New Programs 
     637 
     638  If you develop a new program, and you want it to be of the greatest 
     639possible use to the public, the best way to achieve this is to make it 
     640free software which everyone can redistribute and change under these terms. 
     641 
     642  To do so, attach the following notices to the program.  It is safest 
     643to attach them to the start of each source file to most effectively 
     644state the exclusion of warranty; and each file should have at least 
     645the "copyright" line and a pointer to where the full notice is found. 
     646 
     647    <one line to give the program's name and a brief idea of what it does.> 
     648    Copyright (C) <year>  <name of author> 
     649 
     650    This program is free software: you can redistribute it and/or modify 
     651    it under the terms of the GNU General Public License as published by 
     652    the Free Software Foundation, either version 3 of the License, or 
     653    (at your option) any later version. 
     654 
     655    This program is distributed in the hope that it will be useful, 
     656    but WITHOUT ANY WARRANTY; without even the implied warranty of 
     657    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the 
     658    GNU General Public License for more details. 
     659 
     660    You should have received a copy of the GNU General Public License 
     661    along with this program.  If not, see <http://www.gnu.org/licenses/>. 
     662 
     663Also add information on how to contact you by electronic and paper mail. 
     664 
     665  If the program does terminal interaction, make it output a short 
     666notice like this when it starts in an interactive mode: 
     667 
     668    <program>  Copyright (C) <year>  <name of author> 
     669    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 
     670    This is free software, and you are welcome to redistribute it 
     671    under certain conditions; type `show c' for details. 
     672 
     673The hypothetical commands `show w' and `show c' should show the appropriate 
     674parts of the General Public License.  Of course, your program's commands 
     675might be different; for a GUI interface, you would use an "about box". 
     676 
     677  You should also get your employer (if you work as a programmer) or school, 
     678if any, to sign a "copyright disclaimer" for the program, if necessary. 
     679For more information on this, and how to apply and follow the GNU GPL, see 
     680<http://www.gnu.org/licenses/>. 
     681 
     682  The GNU General Public License does not permit incorporating your program 
     683into proprietary programs.  If your program is a subroutine library, you 
     684may consider it more useful to permit linking proprietary applications with 
     685the library.  If this is what you want to do, use the GNU Lesser General 
     686Public License instead of this License.  But first, please read 
     687<http://www.gnu.org/philosophy/why-not-lgpl.html>.
