    1:                     GNU GENERAL PUBLIC LICENSE
    2:                        Version 3, 29 June 2007
    3: 
    4:  Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
    5:  Everyone is permitted to copy and distribute verbatim copies
    6:  of this license document, but changing it is not allowed.
    7: 
    8:                             Preamble
    9: 
   10:   The GNU General Public License is a free, copyleft license for
   11: software and other kinds of works.
   12: 
   13:   The licenses for most software and other practical works are designed
   14: to take away your freedom to share and change the works.  By contrast,
   15: the GNU General Public License is intended to guarantee your freedom to
   16: share and change all versions of a program--to make sure it remains free
   17: software for all its users.  We, the Free Software Foundation, use the
   18: GNU General Public License for most of our software; it applies also to
   19: any other work released this way by its authors.  You can apply it to
   20: your programs, too.
   21: 
   22:   When we speak of free software, we are referring to freedom, not
   23: price.  Our General Public Licenses are designed to make sure that you
   24: have the freedom to distribute copies of free software (and charge for
   25: them if you wish), that you receive source code or can get it if you
   26: want it, that you can change the software or use pieces of it in new
   27: free programs, and that you know you can do these things.
   28: 
   29:   To protect your rights, we need to prevent others from denying you
   30: these rights or asking you to surrender the rights.  Therefore, you have
   31: certain responsibilities if you distribute copies of the software, or if
   32: you modify it: responsibilities to respect the freedom of others.
   33: 
   34:   For example, if you distribute copies of such a program, whether
   35: gratis or for a fee, you must pass on to the recipients the same
   36: freedoms that you received.  You must make sure that they, too, receive
   37: or can get the source code.  And you must show them these terms so they
   38: know their rights.
   39: 
   40:   Developers that use the GNU GPL protect your rights with two steps:
   41: (1) assert copyright on the software, and (2) offer you this License
   42: giving you legal permission to copy, distribute and/or modify it.
   43: 
   44:   For the developers' and authors' protection, the GPL clearly explains
   45: that there is no warranty for this free software.  For both users' and
   46: authors' sake, the GPL requires that modified versions be marked as
   47: changed, so that their problems will not be attributed erroneously to
   48: authors of previous versions.
   49: 
   50:   Some devices are designed to deny users access to install or run
   51: modified versions of the software inside them, although the manufacturer
   52: can do so.  This is fundamentally incompatible with the aim of
   53: protecting users' freedom to change the software.  The systematic
   54: pattern of such abuse occurs in the area of products for individuals to
   55: use, which is precisely where it is most unacceptable.  Therefore, we
   56: have designed this version of the GPL to prohibit the practice for those
   57: products.  If such problems arise substantially in other domains, we
   58: stand ready to extend this provision to those domains in future versions
   59: of the GPL, as needed to protect the freedom of users.
   60: 
   61:   Finally, every program is threatened constantly by software patents.
   62: States should not allow patents to restrict development and use of
   63: software on general-purpose computers, but in those that do, we wish to
   64: avoid the special danger that patents applied to a free program could
   65: make it effectively proprietary.  To prevent this, the GPL assures that
   66: patents cannot be used to render the program non-free.
   67: 
   68:   The precise terms and conditions for copying, distribution and
   69: modification follow.
   70: 
   71:                        TERMS AND CONDITIONS
   72: 
   73:   0. Definitions.
   74: 
   75:   "This License" refers to version 3 of the GNU General Public License.
   76: 
   77:   "Copyright" also means copyright-like laws that apply to other kinds of
   78: works, such as semiconductor masks.
   79: 
   80:   "The Program" refers to any copyrightable work licensed under this
   81: License.  Each licensee is addressed as "you".  "Licensees" and
   82: "recipients" may be individuals or organizations.
   83: 
   84:   To "modify" a work means to copy from or adapt all or part of the work
   85: in a fashion requiring copyright permission, other than the making of an
   86: exact copy.  The resulting work is called a "modified version" of the
   87: earlier work or a work "based on" the earlier work.
   88: 
   89:   A "covered work" means either the unmodified Program or a work based
   90: on the Program.
   91: 
   92:   To "propagate" a work means to do anything with it that, without
   93: permission, would make you directly or secondarily liable for
   94: infringement under applicable copyright law, except executing it on a
   95: computer or modifying a private copy.  Propagation includes copying,
   96: distribution (with or without modification), making available to the
   97: public, and in some countries other activities as well.
   98: 
   99:   To "convey" a work means any kind of propagation that enables other
  100: parties to make or receive copies.  Mere interaction with a user through
  101: a computer network, with no transfer of a copy, is not conveying.
  102: 
  103:   An interactive user interface displays "Appropriate Legal Notices"
  104: to the extent that it includes a convenient and prominently visible
  105: feature that (1) displays an appropriate copyright notice, and (2)
  106: tells the user that there is no warranty for the work (except to the
  107: extent that warranties are provided), that licensees may convey the
  108: work under this License, and how to view a copy of this License.  If
  109: the interface presents a list of user commands or options, such as a
  110: menu, a prominent item in the list meets this criterion.
  111: 
  112:   1. Source Code.
  113: 
  114:   The "source code" for a work means the preferred form of the work
  115: for making modifications to it.  "Object code" means any non-source
  116: form of a work.
  117: 
  118:   A "Standard Interface" means an interface that either is an official
  119: standard defined by a recognized standards body, or, in the case of
  120: interfaces specified for a particular programming language, one that
  121: is widely used among developers working in that language.
  122: 
  123:   The "System Libraries" of an executable work include anything, other
  124: than the work as a whole, that (a) is included in the normal form of
  125: packaging a Major Component, but which is not part of that Major
  126: Component, and (b) serves only to enable use of the work with that
  127: Major Component, or to implement a Standard Interface for which an
  128: implementation is available to the public in source code form.  A
  129: "Major Component", in this context, means a major essential component
  130: (kernel, window system, and so on) of the specific operating system
  131: (if any) on which the executable work runs, or a compiler used to
  132: produce the work, or an object code interpreter used to run it.
  133: 
  134:   The "Corresponding Source" for a work in object code form means all
  135: the source code needed to generate, install, and (for an executable
  136: work) run the object code and to modify the work, including scripts to
  137: control those activities.  However, it does not include the work's
  138: System Libraries, or general-purpose tools or generally available free
  139: programs which are used unmodified in performing those activities but
  140: which are not part of the work.  For example, Corresponding Source
  141: includes interface definition files associated with source files for
  142: the work, and the source code for shared libraries and dynamically
  143: linked subprograms that the work is specifically designed to require,
  144: such as by intimate data communication or control flow between those
  145: subprograms and other parts of the work.
  146: 
  147:   The Corresponding Source need not include anything that users
  148: can regenerate automatically from other parts of the Corresponding
  149: Source.
  150: 
  151:   The Corresponding Source for a work in source code form is that
  152: same work.
  153: 
  154:   2. Basic Permissions.
  155: 
  156:   All rights granted under this License are granted for the term of
  157: copyright on the Program, and are irrevocable provided the stated
  158: conditions are met.  This License explicitly affirms your unlimited
  159: permission to run the unmodified Program.  The output from running a
  160: covered work is covered by this License only if the output, given its
  161: content, constitutes a covered work.  This License acknowledges your
  162: rights of fair use or other equivalent, as provided by copyright law.
  163: 
  164:   You may make, run and propagate covered works that you do not
  165: convey, without conditions so long as your license otherwise remains
  166: in force.  You may convey covered works to others for the sole purpose
  167: of having them make modifications exclusively for you, or provide you
  168: with facilities for running those works, provided that you comply with
  169: the terms of this License in conveying all material for which you do
  170: not control copyright.  Those thus making or running the covered works
  171: for you must do so exclusively on your behalf, under your direction
  172: and control, on terms that prohibit them from making any copies of
  173: your copyrighted material outside their relationship with you.
  174: 
  175:   Conveying under any other circumstances is permitted solely under
  176: the conditions stated below.  Sublicensing is not allowed; section 10
  177: makes it unnecessary.
  178: 
  179:   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
  180: 
  181:   No covered work shall be deemed part of an effective technological
  182: measure under any applicable law fulfilling obligations under article
  183: 11 of the WIPO copyright treaty adopted on 20 December 1996, or
  184: similar laws prohibiting or restricting circumvention of such
  185: measures.
  186: 
  187:   When you convey a covered work, you waive any legal power to forbid
  188: circumvention of technological measures to the extent such circumvention
  189: is effected by exercising rights under this License with respect to
  190: the covered work, and you disclaim any intention to limit operation or
  191: modification of the work as a means of enforcing, against the work's
  192: users, your or third parties' legal rights to forbid circumvention of
  193: technological measures.
  194: 
  195:   4. Conveying Verbatim Copies.
  196: 
  197:   You may convey verbatim copies of the Program's source code as you
  198: receive it, in any medium, provided that you conspicuously and
  199: appropriately publish on each copy an appropriate copyright notice;
  200: keep intact all notices stating that this License and any
  201: non-permissive terms added in accord with section 7 apply to the code;
  202: keep intact all notices of the absence of any warranty; and give all
  203: recipients a copy of this License along with the Program.
  204: 
  205:   You may charge any price or no price for each copy that you convey,
  206: and you may offer support or warranty protection for a fee.
  207: 
  208:   5. Conveying Modified Source Versions.
  209: 
  210:   You may convey a work based on the Program, or the modifications to
  211: produce it from the Program, in the form of source code under the
  212: terms of section 4, provided that you also meet all of these conditions:
  213: 
  214:     a) The work must carry prominent notices stating that you modified
  215:     it, and giving a relevant date.
  216: 
  217:     b) The work must carry prominent notices stating that it is
  218:     released under this License and any conditions added under section
  219:     7.  This requirement modifies the requirement in section 4 to
  220:     "keep intact all notices".
  221: 
  222:     c) You must license the entire work, as a whole, under this
  223:     License to anyone who comes into possession of a copy.  This
  224:     License will therefore apply, along with any applicable section 7
  225:     additional terms, to the whole of the work, and all its parts,
  226:     regardless of how they are packaged.  This License gives no
  227:     permission to license the work in any other way, but it does not
  228:     invalidate such permission if you have separately received it.
  229: 
  230:     d) If the work has interactive user interfaces, each must display
  231:     Appropriate Legal Notices; however, if the Program has interactive
  232:     interfaces that do not display Appropriate Legal Notices, your
  233:     work need not make them do so.
  234: 
  235:   A compilation of a covered work with other separate and independent
  236: works, which are not by their nature extensions of the covered work,
  237: and which are not combined with it such as to form a larger program,
  238: in or on a volume of a storage or distribution medium, is called an
  239: "aggregate" if the compilation and its resulting copyright are not
  240: used to limit the access or legal rights of the compilation's users
  241: beyond what the individual works permit.  Inclusion of a covered work
  242: in an aggregate does not cause this License to apply to the other
  243: parts of the aggregate.
  244: 
  245:   6. Conveying Non-Source Forms.
  246: 
  247:   You may convey a covered work in object code form under the terms
  248: of sections 4 and 5, provided that you also convey the
  249: machine-readable Corresponding Source under the terms of this License,
  250: in one of these ways:
  251: 
  252:     a) Convey the object code in, or embodied in, a physical product
  253:     (including a physical distribution medium), accompanied by the
  254:     Corresponding Source fixed on a durable physical medium
  255:     customarily used for software interchange.
  256: 
  257:     b) Convey the object code in, or embodied in, a physical product
  258:     (including a physical distribution medium), accompanied by a
  259:     written offer, valid for at least three years and valid for as
  260:     long as you offer spare parts or customer support for that product
  261:     model, to give anyone who possesses the object code either (1) a
  262:     copy of the Corresponding Source for all the software in the
  263:     product that is covered by this License, on a durable physical
  264:     medium customarily used for software interchange, for a price no
  265:     more than your reasonable cost of physically performing this
  266:     conveying of source, or (2) access to copy the
  267:     Corresponding Source from a network server at no charge.
  268: 
  269:     c) Convey individual copies of the object code with a copy of the
  270:     written offer to provide the Corresponding Source.  This
  271:     alternative is allowed only occasionally and noncommercially, and
  272:     only if you received the object code with such an offer, in accord
  273:     with subsection 6b.
  274: 
  275:     d) Convey the object code by offering access from a designated
  276:     place (gratis or for a charge), and offer equivalent access to the
  277:     Corresponding Source in the same way through the same place at no
  278:     further charge.  You need not require recipients to copy the
  279:     Corresponding Source along with the object code.  If the place to
  280:     copy the object code is a network server, the Corresponding Source
  281:     may be on a different server (operated by you or a third party)
  282:     that supports equivalent copying facilities, provided you maintain
  283:     clear directions next to the object code saying where to find the
  284:     Corresponding Source.  Regardless of what server hosts the
  285:     Corresponding Source, you remain obligated to ensure that it is
  286:     available for as long as needed to satisfy these requirements.
  287: 
  288:     e) Convey the object code using peer-to-peer transmission, provided
  289:     you inform other peers where the object code and Corresponding
  290:     Source of the work are being offered to the general public at no
  291:     charge under subsection 6d.
  292: 
  293:   A separable portion of the object code, whose source code is excluded
  294: from the Corresponding Source as a System Library, need not be
  295: included in conveying the object code work.
  296: 
  297:   A "User Product" is either (1) a "consumer product", which means any
  298: tangible personal property which is normally used for personal, family,
  299: or household purposes, or (2) anything designed or sold for incorporation
  300: into a dwelling.  In determining whether a product is a consumer product,
  301: doubtful cases shall be resolved in favor of coverage.  For a particular
  302: product received by a particular user, "normally used" refers to a
  303: typical or common use of that class of product, regardless of the status
  304: of the particular user or of the way in which the particular user
  305: actually uses, or expects or is expected to use, the product.  A product
  306: is a consumer product regardless of whether the product has substantial
  307: commercial, industrial or non-consumer uses, unless such uses represent
  308: the only significant mode of use of the product.
  309: 
  310:   "Installation Information" for a User Product means any methods,
  311: procedures, authorization keys, or other information required to install
  312: and execute modified versions of a covered work in that User Product from
  313: a modified version of its Corresponding Source.  The information must
  314: suffice to ensure that the continued functioning of the modified object
  315: code is in no case prevented or interfered with solely because
  316: modification has been made.
  317: 
  318:   If you convey an object code work under this section in, or with, or
  319: specifically for use in, a User Product, and the conveying occurs as
  320: part of a transaction in which the right of possession and use of the
  321: User Product is transferred to the recipient in perpetuity or for a
  322: fixed term (regardless of how the transaction is characterized), the
  323: Corresponding Source conveyed under this section must be accompanied
  324: by the Installation Information.  But this requirement does not apply
  325: if neither you nor any third party retains the ability to install
  326: modified object code on the User Product (for example, the work has
  327: been installed in ROM).
  328: 
  329:   The requirement to provide Installation Information does not include a
  330: requirement to continue to provide support service, warranty, or updates
  331: for a work that has been modified or installed by the recipient, or for
  332: the User Product in which it has been modified or installed.  Access to a
  333: network may be denied when the modification itself materially and
  334: adversely affects the operation of the network or violates the rules and
  335: protocols for communication across the network.
  336: 
  337:   Corresponding Source conveyed, and Installation Information provided,
  338: in accord with this section must be in a format that is publicly
  339: documented (and with an implementation available to the public in
  340: source code form), and must require no special password or key for
  341: unpacking, reading or copying.
  342: 
  343:   7. Additional Terms.
  344: 
  345:   "Additional permissions" are terms that supplement the terms of this
  346: License by making exceptions from one or more of its conditions.
  347: Additional permissions that are applicable to the entire Program shall
  348: be treated as though they were included in this License, to the extent
  349: that they are valid under applicable law.  If additional permissions
  350: apply only to part of the Program, that part may be used separately
  351: under those permissions, but the entire Program remains governed by
  352: this License without regard to the additional permissions.
  353: 
  354:   When you convey a copy of a covered work, you may at your option
  355: remove any additional permissions from that copy, or from any part of
  356: it.  (Additional permissions may be written to require their own
  357: removal in certain cases when you modify the work.)  You may place
  358: additional permissions on material, added by you to a covered work,
  359: for which you have or can give appropriate copyright permission.
  360: 
  361:   Notwithstanding any other provision of this License, for material you
  362: add to a covered work, you may (if authorized by the copyright holders of
  363: that material) supplement the terms of this License with terms:
  364: 
  365:     a) Disclaiming warranty or limiting liability differently from the
  366:     terms of sections 15 and 16 of this License; or
  367: 
  368:     b) Requiring preservation of specified reasonable legal notices or
  369:     author attributions in that material or in the Appropriate Legal
  370:     Notices displayed by works containing it; or
  371: 
  372:     c) Prohibiting misrepresentation of the origin of that material, or
  373:     requiring that modified versions of such material be marked in
  374:     reasonable ways as different from the original version; or
  375: 
  376:     d) Limiting the use for publicity purposes of names of licensors or
  377:     authors of the material; or
  378: 
  379:     e) Declining to grant rights under trademark law for use of some
  380:     trade names, trademarks, or service marks; or
  381: 
  382:     f) Requiring indemnification of licensors and authors of that
  383:     material by anyone who conveys the material (or modified versions of
  384:     it) with contractual assumptions of liability to the recipient, for
  385:     any liability that these contractual assumptions directly impose on
  386:     those licensors and authors.
  387: 
  388:   All other non-permissive additional terms are considered "further
  389: restrictions" within the meaning of section 10.  If the Program as you
  390: received it, or any part of it, contains a notice stating that it is
  391: governed by this License along with a term that is a further
  392: restriction, you may remove that term.  If a license document contains
  393: a further restriction but permits relicensing or conveying under this
  394: License, you may add to a covered work material governed by the terms
  395: of that license document, provided that the further restriction does
  396: not survive such relicensing or conveying.
  397: 
  398:   If you add terms to a covered work in accord with this section, you
  399: must place, in the relevant source files, a statement of the
  400: additional terms that apply to those files, or a notice indicating
  401: where to find the applicable terms.
  402: 
  403:   Additional terms, permissive or non-permissive, may be stated in the
  404: form of a separately written license, or stated as exceptions;
  405: the above requirements apply either way.
  406: 
  407:   8. Termination.
  408: 
  409:   You may not propagate or modify a covered work except as expressly
  410: provided under this License.  Any attempt otherwise to propagate or
  411: modify it is void, and will automatically terminate your rights under
  412: this License (including any patent licenses granted under the third
  413: paragraph of section 11).
  414: 
  415:   However, if you cease all violation of this License, then your
  416: license from a particular copyright holder is reinstated (a)
  417: provisionally, unless and until the copyright holder explicitly and
  418: finally terminates your license, and (b) permanently, if the copyright
  419: holder fails to notify you of the violation by some reasonable means
  420: prior to 60 days after the cessation.
  421: 
  422:   Moreover, your license from a particular copyright holder is
  423: reinstated permanently if the copyright holder notifies you of the
  424: violation by some reasonable means, this is the first time you have
  425: received notice of violation of this License (for any work) from that
  426: copyright holder, and you cure the violation prior to 30 days after
  427: your receipt of the notice.
  428: 
  429:   Termination of your rights under this section does not terminate the
  430: licenses of parties who have received copies or rights from you under
  431: this License.  If your rights have been terminated and not permanently
  432: reinstated, you do not qualify to receive new licenses for the same
  433: material under section 10.
  434: 
  435:   9. Acceptance Not Required for Having Copies.
  436: 
  437:   You are not required to accept this License in order to receive or
  438: run a copy of the Program.  Ancillary propagation of a covered work
  439: occurring solely as a consequence of using peer-to-peer transmission
  440: to receive a copy likewise does not require acceptance.  However,
  441: nothing other than this License grants you permission to propagate or
  442: modify any covered work.  These actions infringe copyright if you do
  443: not accept this License.  Therefore, by modifying or propagating a
  444: covered work, you indicate your acceptance of this License to do so.
  445: 
  446:   10. Automatic Licensing of Downstream Recipients.
  447: 
  448:   Each time you convey a covered work, the recipient automatically
  449: receives a license from the original licensors, to run, modify and
  450: propagate that work, subject to this License.  You are not responsible
  451: for enforcing compliance by third parties with this License.
  452: 
  453:   An "entity transaction" is a transaction transferring control of an
  454: organization, or substantially all assets of one, or subdividing an
  455: organization, or merging organizations.  If propagation of a covered
  456: work results from an entity transaction, each party to that
  457: transaction who receives a copy of the work also receives whatever
  458: licenses to the work the party's predecessor in interest had or could
  459: give under the previous paragraph, plus a right to possession of the
  460: Corresponding Source of the work from the predecessor in interest, if
  461: the predecessor has it or can get it with reasonable efforts.
  462: 
  463:   You may not impose any further restrictions on the exercise of the
  464: rights granted or affirmed under this License.  For example, you may
  465: not impose a license fee, royalty, or other charge for exercise of
  466: rights granted under this License, and you may not initiate litigation
  467: (including a cross-claim or counterclaim in a lawsuit) alleging that
  468: any patent claim is infringed by making, using, selling, offering for
  469: sale, or importing the Program or any portion of it.
  470: 
  471:   11. Patents.
  472: 
  473:   A "contributor" is a copyright holder who authorizes use under this
  474: License of the Program or a work on which the Program is based.  The
  475: work thus licensed is called the contributor's "contributor version".
  476: 
  477:   A contributor's "essential patent claims" are all patent claims
  478: owned or controlled by the contributor, whether already acquired or
  479: hereafter acquired, that would be infringed by some manner, permitted
  480: by this License, of making, using, or selling its contributor version,
  481: but do not include claims that would be infringed only as a
  482: consequence of further modification of the contributor version.  For
  483: purposes of this definition, "control" includes the right to grant
  484: patent sublicenses in a manner consistent with the requirements of
  485: this License.
  486: 
  487:   Each contributor grants you a non-exclusive, worldwide, royalty-free
  488: patent license under the contributor's essential patent claims, to
  489: make, use, sell, offer for sale, import and otherwise run, modify and
  490: propagate the contents of its contributor version.
  491: 
  492:   In the following three paragraphs, a "patent license" is any express
  493: agreement or commitment, however denominated, not to enforce a patent
  494: (such as an express permission to practice a patent or covenant not to
  495: sue for patent infringement).  To "grant" such a patent license to a
  496: party means to make such an agreement or commitment not to enforce a
  497: patent against the party.
  498: 
  499:   If you convey a covered work, knowingly relying on a patent license,
  500: and the Corresponding Source of the work is not available for anyone
  501: to copy, free of charge and under the terms of this License, through a
  502: publicly available network server or other readily accessible means,
  503: then you must either (1) cause the Corresponding Source to be so
  504: available, or (2) arrange to deprive yourself of the benefit of the
  505: patent license for this particular work, or (3) arrange, in a manner
  506: consistent with the requirements of this License, to extend the patent
  507: license to downstream recipients.  "Knowingly relying" means you have
  508: actual knowledge that, but for the patent license, your conveying the
  509: covered work in a country, or your recipient's use of the covered work
  510: in a country, would infringe one or more identifiable patents in that
  511: country that you have reason to believe are valid.
  512: 
  513:   If, pursuant to or in connection with a single transaction or
  514: arrangement, you convey, or propagate by procuring conveyance of, a
  515: covered work, and grant a patent license to some of the parties
  516: receiving the covered work authorizing them to use, propagate, modify
  517: or convey a specific copy of the covered work, then the patent license
  518: you grant is automatically extended to all recipients of the covered
  519: work and works based on it.
  520: 
  521:   A patent license is "discriminatory" if it does not include within
  522: the scope of its coverage, prohibits the exercise of, or is
  523: conditioned on the non-exercise of one or more of the rights that are
  524: specifically granted under this License.  You may not convey a covered
  525: work if you are a party to an arrangement with a third party that is
  526: in the business of distributing software, under which you make payment
  527: to the third party based on the extent of your activity of conveying
  528: the work, and under which the third party grants, to any of the
  529: parties who would receive the covered work from you, a discriminatory
  530: patent license (a) in connection with copies of the covered work
  531: conveyed by you (or copies made from those copies), or (b) primarily
  532: for and in connection with specific products or compilations that
  533: contain the covered work, unless you entered into that arrangement,
  534: or that patent license was granted, prior to 28 March 2007.
  535: 
  536:   Nothing in this License shall be construed as excluding or limiting
  537: any implied license or other defenses to infringement that may
  538: otherwise be available to you under applicable patent law.
  539: 
  540:   12. No Surrender of Others' Freedom.
  541: 
  542:   If conditions are imposed on you (whether by court order, agreement or
  543: otherwise) that contradict the conditions of this License, they do not
  544: excuse you from the conditions of this License.  If you cannot convey a
  545: covered work so as to satisfy simultaneously your obligations under this
  546: License and any other pertinent obligations, then as a consequence you may
  547: not convey it at all.  For example, if you agree to terms that obligate you
  548: to collect a royalty for further conveying from those to whom you convey
  549: the Program, the only way you could satisfy both those terms and this
  550: License would be to refrain entirely from conveying the Program.
  551: 
  552:   13. Use with the GNU Affero General Public License.
  553: 
  554:   Notwithstanding any other provision of this License, you have
  555: permission to link or combine any covered work with a work licensed
  556: under version 3 of the GNU Affero General Public License into a single
  557: combined work, and to convey the resulting work.  The terms of this
  558: License will continue to apply to the part which is the covered work,
  559: but the special requirements of the GNU Affero General Public License,
  560: section 13, concerning interaction through a network will apply to the
  561: combination as such.
  562: 
  563:   14. Revised Versions of this License.
  564: 
  565:   The Free Software Foundation may publish revised and/or new versions of
  566: the GNU General Public License from time to time.  Such new versions will
  567: be similar in spirit to the present version, but may differ in detail to
  568: address new problems or concerns.
  569: 
  570:   Each version is given a distinguishing version number.  If the
  571: Program specifies that a certain numbered version of the GNU General
  572: Public License "or any later version" applies to it, you have the
  573: option of following the terms and conditions either of that numbered
  574: version or of any later version published by the Free Software
  575: Foundation.  If the Program does not specify a version number of the
  576: GNU General Public License, you may choose any version ever published
  577: by the Free Software Foundation.
  578: 
  579:   If the Program specifies that a proxy can decide which future
  580: versions of the GNU General Public License can be used, that proxy's
  581: public statement of acceptance of a version permanently authorizes you
  582: to choose that version for the Program.
  583: 
  584:   Later license versions may give you additional or different
  585: permissions.  However, no additional obligations are imposed on any
  586: author or copyright holder as a result of your choosing to follow a
  587: later version.
  588: 
  589:   15. Disclaimer of Warranty.
  590: 
  591:   THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
  592: APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
  593: HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
  594: OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
  595: THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
  596: PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
  597: IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
  598: ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  599: 
  600:   16. Limitation of Liability.
  601: 
  602:   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
  603: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
  604: THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
  605: GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
  606: USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
  607: DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
  608: PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
  609: EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
  610: SUCH DAMAGES.
  611: 
  612:   17. Interpretation of Sections 15 and 16.
  613: 
  614:   If the disclaimer of warranty and limitation of liability provided
  615: above cannot be given local legal effect according to their terms,
  616: reviewing courts shall apply local law that most closely approximates
  617: an absolute waiver of all civil liability in connection with the
  618: Program, unless a warranty or assumption of liability accompanies a
  619: copy of the Program in return for a fee.
  620: 
  621:                      END OF TERMS AND CONDITIONS
  622: 
  623:             How to Apply These Terms to Your New Programs
  624: 
  625:   If you develop a new program, and you want it to be of the greatest
  626: possible use to the public, the best way to achieve this is to make it
  627: free software which everyone can redistribute and change under these terms.
  628: 
  629:   To do so, attach the following notices to the program.  It is safest
  630: to attach them to the start of each source file to most effectively
  631: state the exclusion of warranty; and each file should have at least
  632: the "copyright" line and a pointer to where the full notice is found.
  633: 
  634:     <one line to give the program's name and a brief idea of what it does.>
  635:     Copyright (C) <year>  <name of author>
  636: 
  637:     This program is free software: you can redistribute it and/or modify
  638:     it under the terms of the GNU General Public License as published by
  639:     the Free Software Foundation, either version 3 of the License, or
  640:     (at your option) any later version.
  641: 
  642:     This program is distributed in the hope that it will be useful,
  643:     but WITHOUT ANY WARRANTY; without even the implied warranty of
  644:     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
  645:     GNU General Public License for more details.
  646: 
  647:     You should have received a copy of the GNU General Public License
  648:     along with this program.  If not, see <http://www.gnu.org/licenses/>.
  649: 
  650: Also add information on how to contact you by electronic and paper mail.
  651: 
  652:   If the program does terminal interaction, make it output a short
  653: notice like this when it starts in an interactive mode:
  654: 
  655:     <program>  Copyright (C) <year>  <name of author>
  656:     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
  657:     This is free software, and you are welcome to redistribute it
  658:     under certain conditions; type `show c' for details.
  659: 
  660: The hypothetical commands `show w' and `show c' should show the appropriate
  661: parts of the General Public License.  Of course, your program's commands
  662: might be different; for a GUI interface, you would use an "about box".
  663: 
  664:   You should also get your employer (if you work as a programmer) or school,
  665: if any, to sign a "copyright disclaimer" for the program, if necessary.
  666: For more information on this, and how to apply and follow the GNU GPL, see
  667: <http://www.gnu.org/licenses/>.
  668: 
  669:   The GNU General Public License does not permit incorporating your program
  670: into proprietary programs.  If your program is a subroutine library, you
  671: may consider it more useful to permit linking proprietary applications with
  672: the library.  If this is what you want to do, use the GNU Lesser General
  673: Public License instead of this License.  But first, please read
  674: <http://www.gnu.org/philosophy/why-not-lgpl.html>.
