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