2.24 +\renewcommand{\abstractname}{Preamble}
2.25 +\begin{abstract}
2.26 +The GNU General Public License is a free, copyleft license for
2.27 +software and other kinds of works.
2.28 +
2.29 +The licenses for most software and other practical works are designed
2.30 +to take away your freedom to share and change the works.  By contrast,
2.31 +the GNU General Public License is intended to guarantee your freedom to
2.32 +share and change all versions of a program--to make sure it remains free
2.33 +software for all its users.  We, the Free Software Foundation, use the
2.34 +GNU General Public License for most of our software; it applies also to
2.35 +any other work released this way by its authors.  You can apply it to
2.37 +
2.38 +When we speak of free software, we are referring to freedom, not
2.39 +price.  Our General Public Licenses are designed to make sure that you
2.40 +have the freedom to distribute copies of free software (and charge for
2.41 +them if you wish), that you receive source code or can get it if you
2.42 +want it, that you can change the software or use pieces of it in new
2.43 +free programs, and that you know you can do these things.
2.44 +
2.45 +To protect your rights, we need to prevent others from denying you
2.46 +these rights or asking you to surrender the rights.  Therefore, you have
2.47 +certain responsibilities if you distribute copies of the software, or if
2.48 +you modify it: responsibilities to respect the freedom of others.
2.49 +
2.50 +For example, if you distribute copies of such a program, whether
2.51 +gratis or for a fee, you must pass on to the recipients the same
2.52 +freedoms that you received.  You must make sure that they, too, receive
2.53 +or can get the source code.  And you must show them these terms so they
2.54 +know their rights.
2.55 +
2.56 +Developers that use the GNU GPL protect your rights with two steps:
2.57 +(1) assert copyright on the software, and (2) offer you this License
2.58 +giving you legal permission to copy, distribute and/or modify it.
2.59 +
2.60 +For the developers' and authors' protection, the GPL clearly explains
2.61 +that there is no warranty for this free software.  For both users' and
2.62 +authors' sake, the GPL requires that modified versions be marked as
2.63 +changed, so that their problems will not be attributed erroneously to
2.64 +authors of previous versions.
2.65 +
2.66 +Some devices are designed to deny users access to install or run
2.67 +modified versions of the software inside them, although the manufacturer
2.68 +can do so.  This is fundamentally incompatible with the aim of
2.69 +protecting users' freedom to change the software.  The systematic
2.70 +pattern of such abuse occurs in the area of products for individuals to
2.71 +use, which is precisely where it is most unacceptable.  Therefore, we
2.72 +have designed this version of the GPL to prohibit the practice for those
2.73 +products.  If such problems arise substantially in other domains, we
2.74 +stand ready to extend this provision to those domains in future versions
2.75 +of the GPL, as needed to protect the freedom of users.
2.76 +
2.77 +Finally, every program is threatened constantly by software patents.
2.78 +States should not allow patents to restrict development and use of
2.79 +software on general-purpose computers, but in those that do, we wish to
2.80 +avoid the special danger that patents applied to a free program could
2.81 +make it effectively proprietary.  To prevent this, the GPL assures that
2.82 +patents cannot be used to render the program non-free.
2.83 +
2.84 +The precise terms and conditions for copying, distribution and
2.85 +modification follow.

2.92 +
2.93 +\begin{enumerate}
2.94 +
2.96 +
2.97 +\item Definitions.
2.98 +
2.99 +This License'' refers to version 3 of the GNU General Public License.
2.100 +
2.101 +Copyright'' also means copyright-like laws that apply to other kinds of
2.102 +works, such as semiconductor masks.
2.103 +
2.104 +The Program'' refers to any copyrightable work licensed under this
2.105 +License.  Each licensee is addressed as you''.  Licensees'' and
2.106 +recipients'' may be individuals or organizations.
2.107 +
2.108 +To modify'' a work means to copy from or adapt all or part of the work
2.109 +in a fashion requiring copyright permission, other than the making of an
2.110 +exact copy.  The resulting work is called a modified version'' of the
2.111 +earlier work or a work based on'' the earlier work.
2.112 +
2.113 +A covered work'' means either the unmodified Program or a work based
2.114 +on the Program.
2.115 +
2.116 +To propagate'' a work means to do anything with it that, without
2.117 +permission, would make you directly or secondarily liable for
2.118 +infringement under applicable copyright law, except executing it on a
2.119 +computer or modifying a private copy.  Propagation includes copying,
2.120 +distribution (with or without modification), making available to the
2.121 +public, and in some countries other activities as well.
2.122 +
2.123 +To convey'' a work means any kind of propagation that enables other
2.124 +parties to make or receive copies.  Mere interaction with a user through
2.125 +a computer network, with no transfer of a copy, is not conveying.
2.126 +
2.127 +An interactive user interface displays Appropriate Legal Notices''
2.128 +to the extent that it includes a convenient and prominently visible
2.129 +feature that (1) displays an appropriate copyright notice, and (2)
2.130 +tells the user that there is no warranty for the work (except to the
2.131 +extent that warranties are provided), that licensees may convey the
2.132 +work under this License, and how to view a copy of this License.  If
2.133 +the interface presents a list of user commands or options, such as a
2.134 +menu, a prominent item in the list meets this criterion.
2.135 +
2.136 +\item Source Code.
2.137 +
2.138 +The source code'' for a work means the preferred form of the work
2.139 +for making modifications to it.  Object code'' means any non-source
2.140 +form of a work.
2.141 +
2.142 +A Standard Interface'' means an interface that either is an official
2.143 +standard defined by a recognized standards body, or, in the case of
2.144 +interfaces specified for a particular programming language, one that
2.145 +is widely used among developers working in that language.
2.146 +
2.147 +The System Libraries'' of an executable work include anything, other
2.148 +than the work as a whole, that (a) is included in the normal form of
2.149 +packaging a Major Component, but which is not part of that Major
2.150 +Component, and (b) serves only to enable use of the work with that
2.151 +Major Component, or to implement a Standard Interface for which an
2.152 +implementation is available to the public in source code form.  A
2.153 +Major Component'', in this context, means a major essential component
2.154 +(kernel, window system, and so on) of the specific operating system
2.155 +(if any) on which the executable work runs, or a compiler used to
2.156 +produce the work, or an object code interpreter used to run it.
2.157 +
2.158 +The Corresponding Source'' for a work in object code form means all
2.159 +the source code needed to generate, install, and (for an executable
2.160 +work) run the object code and to modify the work, including scripts to
2.161 +control those activities.  However, it does not include the work's
2.162 +System Libraries, or general-purpose tools or generally available free
2.163 +programs which are used unmodified in performing those activities but
2.164 +which are not part of the work.  For example, Corresponding Source
2.165 +includes interface definition files associated with source files for
2.166 +the work, and the source code for shared libraries and dynamically
2.167 +linked subprograms that the work is specifically designed to require,
2.168 +such as by intimate data communication or control flow between those
2.169 +subprograms and other parts of the work.
2.170 +
2.171 +The Corresponding Source need not include anything that users
2.172 +can regenerate automatically from other parts of the Corresponding
2.173 +Source.
2.174 +
2.175 +The Corresponding Source for a work in source code form is that
2.176 +same work.
2.177 +
2.178 +\item Basic Permissions.
2.179 +
2.180 +All rights granted under this License are granted for the term of
2.181 +copyright on the Program, and are irrevocable provided the stated
2.183 +permission to run the unmodified Program.  The output from running a
2.184 +covered work is covered by this License only if the output, given its
2.185 +content, constitutes a covered work.  This License acknowledges your
2.186 +rights of fair use or other equivalent, as provided by copyright law.
2.187 +
2.188 +You may make, run and propagate covered works that you do not
2.190 +in force.  You may convey covered works to others for the sole purpose
2.191 +of having them make modifications exclusively for you, or provide you
2.192 +with facilities for running those works, provided that you comply with
2.193 +the terms of this License in conveying all material for which you do
2.194 +not control copyright.  Those thus making or running the covered works
2.195 +for you must do so exclusively on your behalf, under your direction
2.196 +and control, on terms that prohibit them from making any copies of
2.198 +
2.199 +Conveying under any other circumstances is permitted solely under
2.200 +the conditions stated below.  Sublicensing is not allowed; section 10
2.201 +makes it unnecessary.
2.202 +
2.203 +\item Protecting Users' Legal Rights From Anti-Circumvention Law.
2.204 +
2.205 +No covered work shall be deemed part of an effective technological
2.206 +measure under any applicable law fulfilling obligations under article
2.207 +11 of the WIPO copyright treaty adopted on 20 December 1996, or
2.208 +similar laws prohibiting or restricting circumvention of such
2.209 +measures.
2.210 +
2.211 +When you convey a covered work, you waive any legal power to forbid
2.212 +circumvention of technological measures to the extent such circumvention
2.213 +is effected by exercising rights under this License with respect to
2.214 +the covered work, and you disclaim any intention to limit operation or
2.215 +modification of the work as a means of enforcing, against the work's
2.216 +users, your or third parties' legal rights to forbid circumvention of
2.217 +technological measures.
2.218 +
2.219 +\item Conveying Verbatim Copies.
2.220 +
2.221 +You may convey verbatim copies of the Program's source code as you
2.222 +receive it, in any medium, provided that you conspicuously and
2.223 +appropriately publish on each copy an appropriate copyright notice;
2.224 +keep intact all notices stating that this License and any
2.225 +non-permissive terms added in accord with section 7 apply to the code;
2.226 +keep intact all notices of the absence of any warranty; and give all
2.227 +recipients a copy of this License along with the Program.
2.228 +
2.229 +You may charge any price or no price for each copy that you convey,
2.230 +and you may offer support or warranty protection for a fee.
2.231 +
2.232 +\item Conveying Modified Source Versions.
2.233 +
2.234 +You may convey a work based on the Program, or the modifications to
2.235 +produce it from the Program, in the form of source code under the
2.236 +terms of section 4, provided that you also meet all of these conditions:
2.237 +  \begin{enumerate}
2.238 +  \item The work must carry prominent notices stating that you modified
2.239 +  it, and giving a relevant date.
2.240 +
2.241 +  \item The work must carry prominent notices stating that it is
2.242 +  released under this License and any conditions added under section
2.243 +  7.  This requirement modifies the requirement in section 4 to
2.244 +  keep intact all notices''.
2.245 +
2.246 +  \item You must license the entire work, as a whole, under this
2.247 +  License to anyone who comes into possession of a copy.  This
2.248 +  License will therefore apply, along with any applicable section 7
2.249 +  additional terms, to the whole of the work, and all its parts,
2.250 +  regardless of how they are packaged.  This License gives no
2.251 +  permission to license the work in any other way, but it does not
2.252 +  invalidate such permission if you have separately received it.
2.253 +
2.254 +  \item If the work has interactive user interfaces, each must display
2.255 +  Appropriate Legal Notices; however, if the Program has interactive
2.256 +  interfaces that do not display Appropriate Legal Notices, your
2.257 +  work need not make them do so.
2.258 +\end{enumerate}
2.259 +A compilation of a covered work with other separate and independent
2.260 +works, which are not by their nature extensions of the covered work,
2.261 +and which are not combined with it such as to form a larger program,
2.262 +in or on a volume of a storage or distribution medium, is called an
2.263 +aggregate'' if the compilation and its resulting copyright are not
2.264 +used to limit the access or legal rights of the compilation's users
2.265 +beyond what the individual works permit.  Inclusion of a covered work
2.266 +in an aggregate does not cause this License to apply to the other
2.267 +parts of the aggregate.
2.268 +
2.269 +\item Conveying Non-Source Forms.
2.270 +
2.271 +You may convey a covered work in object code form under the terms
2.272 +of sections 4 and 5, provided that you also convey the
2.274 +in one of these ways:
2.275 +  \begin{enumerate}
2.276 +  \item Convey the object code in, or embodied in, a physical product
2.277 +  (including a physical distribution medium), accompanied by the
2.278 +  Corresponding Source fixed on a durable physical medium
2.279 +  customarily used for software interchange.
2.280 +
2.281 +  \item Convey the object code in, or embodied in, a physical product
2.282 +  (including a physical distribution medium), accompanied by a
2.283 +  written offer, valid for at least three years and valid for as
2.284 +  long as you offer spare parts or customer support for that product
2.285 +  model, to give anyone who possesses the object code either (1) a
2.286 +  copy of the Corresponding Source for all the software in the
2.287 +  product that is covered by this License, on a durable physical
2.288 +  medium customarily used for software interchange, for a price no
2.289 +  more than your reasonable cost of physically performing this
2.291 +  Corresponding Source from a network server at no charge.
2.292 +
2.293 +  \item Convey individual copies of the object code with a copy of the
2.294 +  written offer to provide the Corresponding Source.  This
2.295 +  alternative is allowed only occasionally and noncommercially, and
2.296 +  only if you received the object code with such an offer, in accord
2.297 +  with subsection 6b.
2.298 +
2.299 +  \item Convey the object code by offering access from a designated
2.300 +  place (gratis or for a charge), and offer equivalent access to the
2.301 +  Corresponding Source in the same way through the same place at no
2.302 +  further charge.  You need not require recipients to copy the
2.303 +  Corresponding Source along with the object code.  If the place to
2.304 +  copy the object code is a network server, the Corresponding Source
2.305 +  may be on a different server (operated by you or a third party)
2.306 +  that supports equivalent copying facilities, provided you maintain
2.307 +  clear directions next to the object code saying where to find the
2.308 +  Corresponding Source.  Regardless of what server hosts the
2.309 +  Corresponding Source, you remain obligated to ensure that it is
2.310 +  available for as long as needed to satisfy these requirements.
2.311 +
2.312 +  \item Convey the object code using peer-to-peer transmission, provided
2.313 +  you inform other peers where the object code and Corresponding
2.314 +  Source of the work are being offered to the general public at no
2.315 +  charge under subsection 6d.
2.316 +  \end{enumerate}
2.317 +
2.318 +A separable portion of the object code, whose source code is excluded
2.319 +from the Corresponding Source as a System Library, need not be
2.320 +included in conveying the object code work.
2.321 +
2.322 +A User Product'' is either (1) a consumer product'', which means any
2.323 +tangible personal property which is normally used for personal, family,
2.324 +or household purposes, or (2) anything designed or sold for incorporation
2.325 +into a dwelling.  In determining whether a product is a consumer product,
2.326 +doubtful cases shall be resolved in favor of coverage.  For a particular
2.327 +product received by a particular user, normally used'' refers to a
2.328 +typical or common use of that class of product, regardless of the status
2.329 +of the particular user or of the way in which the particular user
2.330 +actually uses, or expects or is expected to use, the product.  A product
2.331 +is a consumer product regardless of whether the product has substantial
2.332 +commercial, industrial or non-consumer uses, unless such uses represent
2.333 +the only significant mode of use of the product.
2.334 +
2.335 +Installation Information'' for a User Product means any methods,
2.336 +procedures, authorization keys, or other information required to install
2.337 +and execute modified versions of a covered work in that User Product from
2.338 +a modified version of its Corresponding Source.  The information must
2.339 +suffice to ensure that the continued functioning of the modified object
2.340 +code is in no case prevented or interfered with solely because
2.342 +
2.343 +If you convey an object code work under this section in, or with, or
2.344 +specifically for use in, a User Product, and the conveying occurs as
2.345 +part of a transaction in which the right of possession and use of the
2.346 +User Product is transferred to the recipient in perpetuity or for a
2.347 +fixed term (regardless of how the transaction is characterized), the
2.348 +Corresponding Source conveyed under this section must be accompanied
2.349 +by the Installation Information.  But this requirement does not apply
2.350 +if neither you nor any third party retains the ability to install
2.351 +modified object code on the User Product (for example, the work has
2.352 +been installed in ROM).
2.353 +
2.354 +The requirement to provide Installation Information does not include a
2.355 +requirement to continue to provide support service, warranty, or updates
2.356 +for a work that has been modified or installed by the recipient, or for
2.357 +the User Product in which it has been modified or installed.  Access to a
2.358 +network may be denied when the modification itself materially and
2.359 +adversely affects the operation of the network or violates the rules and
2.360 +protocols for communication across the network.
2.361 +
2.362 +Corresponding Source conveyed, and Installation Information provided,
2.363 +in accord with this section must be in a format that is publicly
2.364 +documented (and with an implementation available to the public in
2.365 +source code form), and must require no special password or key for
2.367 +
2.369 +
2.370 +Additional permissions'' are terms that supplement the terms of this
2.371 +License by making exceptions from one or more of its conditions.
2.372 +Additional permissions that are applicable to the entire Program shall
2.373 +be treated as though they were included in this License, to the extent
2.374 +that they are valid under applicable law.  If additional permissions
2.375 +apply only to part of the Program, that part may be used separately
2.376 +under those permissions, but the entire Program remains governed by
2.378 +
2.379 +When you convey a copy of a covered work, you may at your option
2.380 +remove any additional permissions from that copy, or from any part of
2.381 +it.  (Additional permissions may be written to require their own
2.382 +removal in certain cases when you modify the work.)  You may place
2.383 +additional permissions on material, added by you to a covered work,
2.384 +for which you have or can give appropriate copyright permission.
2.385 +
2.386 +Notwithstanding any other provision of this License, for material you
2.387 +add to a covered work, you may (if authorized by the copyright holders of
2.388 +that material) supplement the terms of this License with terms:
2.389 +  \begin{enumerate}
2.390 +  \item Disclaiming warranty or limiting liability differently from the
2.391 +  terms of sections 15 and 16 of this License; or
2.392 +
2.393 +  \item Requiring preservation of specified reasonable legal notices or
2.394 +  author attributions in that material or in the Appropriate Legal
2.395 +  Notices displayed by works containing it; or
2.396 +
2.397 +  \item Prohibiting misrepresentation of the origin of that material, or
2.398 +  requiring that modified versions of such material be marked in
2.399 +  reasonable ways as different from the original version; or
2.400 +
2.401 +  \item Limiting the use for publicity purposes of names of licensors or
2.402 +  authors of the material; or
2.403 +
2.404 +  \item Declining to grant rights under trademark law for use of some
2.406 +
2.407 +  \item Requiring indemnification of licensors and authors of that
2.408 +  material by anyone who conveys the material (or modified versions of
2.409 +  it) with contractual assumptions of liability to the recipient, for
2.410 +  any liability that these contractual assumptions directly impose on
2.411 +  those licensors and authors.
2.412 +  \end{enumerate}
2.413 +
2.414 +All other non-permissive additional terms are considered further
2.415 +restrictions'' within the meaning of section 10.  If the Program as you
2.416 +received it, or any part of it, contains a notice stating that it is
2.417 +governed by this License along with a term that is a further
2.418 +restriction, you may remove that term.  If a license document contains
2.419 +a further restriction but permits relicensing or conveying under this
2.420 +License, you may add to a covered work material governed by the terms
2.421 +of that license document, provided that the further restriction does
2.422 +not survive such relicensing or conveying.
2.423 +
2.424 +If you add terms to a covered work in accord with this section, you
2.425 +must place, in the relevant source files, a statement of the
2.426 +additional terms that apply to those files, or a notice indicating
2.427 +where to find the applicable terms.
2.428 +
2.429 +Additional terms, permissive or non-permissive, may be stated in the
2.430 +form of a separately written license, or stated as exceptions;
2.431 +the above requirements apply either way.
2.432 +
2.433 +\item Termination.
2.434 +
2.435 +You may not propagate or modify a covered work except as expressly
2.436 +provided under this License.  Any attempt otherwise to propagate or
2.437 +modify it is void, and will automatically terminate your rights under
2.439 +paragraph of section 11).
2.440 +
2.441 +However, if you cease all violation of this License, then your
2.443 +provisionally, unless and until the copyright holder explicitly and
2.445 +holder fails to notify you of the violation by some reasonable means
2.446 +prior to 60 days after the cessation.
2.447 +
2.449 +reinstated permanently if the copyright holder notifies you of the
2.450 +violation by some reasonable means, this is the first time you have
2.451 +received notice of violation of this License (for any work) from that
2.452 +copyright holder, and you cure the violation prior to 30 days after
2.453 +your receipt of the notice.
2.454 +
2.455 +Termination of your rights under this section does not terminate the
2.456 +licenses of parties who have received copies or rights from you under
2.457 +this License.  If your rights have been terminated and not permanently
2.458 +reinstated, you do not qualify to receive new licenses for the same
2.459 +material under section 10.
2.460 +
2.461 +\item Acceptance Not Required for Having Copies.
2.462 +
2.463 +You are not required to accept this License in order to receive or
2.464 +run a copy of the Program.  Ancillary propagation of a covered work
2.465 +occurring solely as a consequence of using peer-to-peer transmission
2.466 +to receive a copy likewise does not require acceptance.  However,
2.467 +nothing other than this License grants you permission to propagate or
2.468 +modify any covered work.  These actions infringe copyright if you do
2.469 +not accept this License.  Therefore, by modifying or propagating a
2.470 +covered work, you indicate your acceptance of this License to do so.
2.471 +
2.472 +\item Automatic Licensing of Downstream Recipients.
2.473 +
2.474 +Each time you convey a covered work, the recipient automatically
2.475 +receives a license from the original licensors, to run, modify and
2.476 +propagate that work, subject to this License.  You are not responsible
2.477 +for enforcing compliance by third parties with this License.
2.478 +
2.479 +An entity transaction'' is a transaction transferring control of an
2.480 +organization, or substantially all assets of one, or subdividing an
2.481 +organization, or merging organizations.  If propagation of a covered
2.482 +work results from an entity transaction, each party to that
2.483 +transaction who receives a copy of the work also receives whatever
2.484 +licenses to the work the party's predecessor in interest had or could
2.485 +give under the previous paragraph, plus a right to possession of the
2.486 +Corresponding Source of the work from the predecessor in interest, if
2.487 +the predecessor has it or can get it with reasonable efforts.
2.488 +
2.489 +You may not impose any further restrictions on the exercise of the
2.490 +rights granted or affirmed under this License.  For example, you may
2.491 +not impose a license fee, royalty, or other charge for exercise of
2.492 +rights granted under this License, and you may not initiate litigation
2.493 +(including a cross-claim or counterclaim in a lawsuit) alleging that
2.494 +any patent claim is infringed by making, using, selling, offering for
2.495 +sale, or importing the Program or any portion of it.
2.496 +
2.497 +\item Patents.
2.498 +
2.499 +A contributor'' is a copyright holder who authorizes use under this
2.500 +License of the Program or a work on which the Program is based.  The
2.501 +work thus licensed is called the contributor's contributor version''.
2.502 +
2.503 +A contributor's essential patent claims'' are all patent claims
2.504 +owned or controlled by the contributor, whether already acquired or
2.505 +hereafter acquired, that would be infringed by some manner, permitted
2.506 +by this License, of making, using, or selling its contributor version,
2.507 +but do not include claims that would be infringed only as a
2.508 +consequence of further modification of the contributor version.  For
2.509 +purposes of this definition, control'' includes the right to grant
2.510 +patent sublicenses in a manner consistent with the requirements of
2.512 +
2.513 +Each contributor grants you a non-exclusive, worldwide, royalty-free
2.514 +patent license under the contributor's essential patent claims, to
2.515 +make, use, sell, offer for sale, import and otherwise run, modify and
2.516 +propagate the contents of its contributor version.
2.517 +
2.518 +In the following three paragraphs, a patent license'' is any express
2.519 +agreement or commitment, however denominated, not to enforce a patent
2.520 +(such as an express permission to practice a patent or covenant not to
2.521 +sue for patent infringement).  To grant'' such a patent license to a
2.522 +party means to make such an agreement or commitment not to enforce a
2.523 +patent against the party.
2.524 +
2.525 +If you convey a covered work, knowingly relying on a patent license,
2.526 +and the Corresponding Source of the work is not available for anyone
2.527 +to copy, free of charge and under the terms of this License, through a
2.528 +publicly available network server or other readily accessible means,
2.529 +then you must either (1) cause the Corresponding Source to be so
2.530 +available, or (2) arrange to deprive yourself of the benefit of the
2.531 +patent license for this particular work, or (3) arrange, in a manner
2.532 +consistent with the requirements of this License, to extend the patent
2.533 +license to downstream recipients.  Knowingly relying'' means you have
2.534 +actual knowledge that, but for the patent license, your conveying the
2.535 +covered work in a country, or your recipient's use of the covered work
2.536 +in a country, would infringe one or more identifiable patents in that
2.537 +country that you have reason to believe are valid.
2.538 +
2.539 +If, pursuant to or in connection with a single transaction or
2.540 +arrangement, you convey, or propagate by procuring conveyance of, a
2.541 +covered work, and grant a patent license to some of the parties
2.542 +receiving the covered work authorizing them to use, propagate, modify
2.543 +or convey a specific copy of the covered work, then the patent license
2.544 +you grant is automatically extended to all recipients of the covered
2.545 +work and works based on it.
2.546 +
2.547 +A patent license is discriminatory'' if it does not include within
2.548 +the scope of its coverage, prohibits the exercise of, or is
2.549 +conditioned on the non-exercise of one or more of the rights that are
2.550 +specifically granted under this License.  You may not convey a covered
2.551 +work if you are a party to an arrangement with a third party that is
2.552 +in the business of distributing software, under which you make payment
2.553 +to the third party based on the extent of your activity of conveying
2.554 +the work, and under which the third party grants, to any of the
2.555 +parties who would receive the covered work from you, a discriminatory
2.556 +patent license (a) in connection with copies of the covered work
2.557 +conveyed by you (or copies made from those copies), or (b) primarily
2.558 +for and in connection with specific products or compilations that
2.559 +contain the covered work, unless you entered into that arrangement,
2.560 +or that patent license was granted, prior to 28 March 2007.
2.561 +
2.562 +Nothing in this License shall be construed as excluding or limiting
2.563 +any implied license or other defenses to infringement that may
2.564 +otherwise be available to you under applicable patent law.
2.565 +
2.566 +\item No Surrender of Others' Freedom.
2.567 +
2.568 +If conditions are imposed on you (whether by court order, agreement or
2.569 +otherwise) that contradict the conditions of this License, they do not
2.570 +excuse you from the conditions of this License.  If you cannot convey a
2.571 +covered work so as to satisfy simultaneously your obligations under this
2.572 +License and any other pertinent obligations, then as a consequence you may
2.573 +not convey it at all.  For example, if you agree to terms that obligate you
2.574 +to collect a royalty for further conveying from those to whom you convey
2.575 +the Program, the only way you could satisfy both those terms and this
2.576 +License would be to refrain entirely from conveying the Program.
2.577 +
2.578 +\item Use with the GNU Affero General Public License.
2.579 +
2.580 +Notwithstanding any other provision of this License, you have
2.581 +permission to link or combine any covered work with a work licensed
2.582 +under version 3 of the GNU Affero General Public License into a single
2.583 +combined work, and to convey the resulting work.  The terms of this
2.584 +License will continue to apply to the part which is the covered work,
2.585 +but the special requirements of the GNU Affero General Public License,
2.586 +section 13, concerning interaction through a network will apply to the
2.587 +combination as such.
2.588 +
2.589 +\item Revised Versions of this License.
2.590 +
2.591 +The Free Software Foundation may publish revised and/or new versions of
2.592 +the GNU General Public License from time to time.  Such new versions will
2.593 +be similar in spirit to the present version, but may differ in detail to
2.594 +address new problems or concerns.
2.595 +
2.596 +Each version is given a distinguishing version number.  If the
2.597 +Program specifies that a certain numbered version of the GNU General
2.598 +Public License or any later version'' applies to it, you have the
2.599 +option of following the terms and conditions either of that numbered
2.600 +version or of any later version published by the Free Software
2.601 +Foundation.  If the Program does not specify a version number of the
2.602 +GNU General Public License, you may choose any version ever published
2.603 +by the Free Software Foundation.
2.604 +
2.605 +If the Program specifies that a proxy can decide which future
2.606 +versions of the GNU General Public License can be used, that proxy's
2.607 +public statement of acceptance of a version permanently authorizes you
2.608 +to choose that version for the Program.
2.609 +
2.611 +permissions.  However, no additional obligations are imposed on any
2.613 +later version.
2.614 +
2.615 +\item Disclaimer of Warranty.
2.616 +
2.617 +\begin{sloppypar}
2.618 + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
2.619 + APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE
2.620 + COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM AS IS''
2.621 + WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
2.622 + INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
2.623 + MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE
2.624 + RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.
2.625 + SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
2.626 + NECESSARY SERVICING, REPAIR OR CORRECTION.
2.627 +\end{sloppypar}
2.628 +
2.629 +\item Limitation of Liability.
2.630 +
2.631 + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
2.632 + WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES
2.633 + AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
2.634 + DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
2.635 + DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
2.636 + (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
2.637 + INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE
2.638 + OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
2.639 + HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
2.640 + DAMAGES.
2.641 +
2.642 +\item Interpretation of Sections 15 and 16.
2.643 +
2.644 +If the disclaimer of warranty and limitation of liability provided
2.645 +above cannot be given local legal effect according to their terms,
2.646 +reviewing courts shall apply local law that most closely approximates
2.647 +an absolute waiver of all civil liability in connection with the
2.648 +Program, unless a warranty or assumption of liability accompanies a
2.649 +copy of the Program in return for a fee.

2.655 +How to Apply These Terms to Your New Programs
2.656 +\end{center}
2.657 +
2.658 +If you develop a new program, and you want it to be of the greatest
2.659 +possible use to the public, the best way to achieve this is to make it
2.660 +free software which everyone can redistribute and change under these terms.
2.661 +
2.662 +To do so, attach the following notices to the program.  It is safest
2.663 +to attach them to the start of each source file to most effectively
2.664 +state the exclusion of warranty; and each file should have at least
2.665 +the copyright'' line and a pointer to where the full notice is found.

2.681 +GNU General Public License for more details.
2.682 +
2.683 +You should have received a copy of the GNU General Public License
2.684 +along with this program.  If not, see <http://www.gnu.org/licenses/>.
2.685 +\end{verbatim}
2.686 +}
2.687 +
2.688 +Also add information on how to contact you by electronic and paper mail.
2.689 +
2.690 +If the program does terminal interaction, make it output a short
2.691 +notice like this when it starts in an interactive mode:
2.692 +
2.693 +{\footnotesize

2.698 +This is free software, and you are welcome to redistribute it
2.699 +under certain conditions; type show c' for details.
2.700 +\end{verbatim}
2.701 +}
2.702 +
2.703 +The hypothetical commands {\tt show w} and {\tt show c} should show
2.704 +the appropriate
2.705 +parts of the General Public License.  Of course, your program's commands
2.706 +might be different; for a GUI interface, you would use an about box''.
2.707 +
2.708 +You should also get your employer (if you work as a programmer) or
2.709 +school, if any, to sign a copyright disclaimer'' for the program, if
2.710 +necessary.  For more information on this, and how to apply and follow
2.711 +the GNU GPL, see \texttt{http://www.gnu.org/licenses/}.
2.712 +
2.713 +The GNU General Public License does not permit incorporating your
2.714 +program into proprietary programs.  If your program is a subroutine
2.715 +library, you may consider it more useful to permit linking proprietary
2.716 +applications with the library.  If this is what you want to do, use

3.5 +                       Version 3, 29 June 2007
3.6 +
3.7 + Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
3.8 + Everyone is permitted to copy and distribute verbatim copies
3.9 + of this license document, but changing it is not allowed.
3.10 +
3.11 +                            Preamble
3.12 +
3.13 +  The GNU General Public License is a free, copyleft license for
3.14 +software and other kinds of works.
3.15 +
3.16 +  The licenses for most software and other practical works are designed
3.17 +to take away your freedom to share and change the works.  By contrast,
3.18 +the GNU General Public License is intended to guarantee your freedom to
3.19 +share and change all versions of a program--to make sure it remains free
3.20 +software for all its users.  We, the Free Software Foundation, use the
3.21 +GNU General Public License for most of our software; it applies also to
3.22 +any other work released this way by its authors.  You can apply it to
3.24 +
3.25 +  When we speak of free software, we are referring to freedom, not
3.26 +price.  Our General Public Licenses are designed to make sure that you
3.27 +have the freedom to distribute copies of free software (and charge for
3.28 +them if you wish), that you receive source code or can get it if you
3.29 +want it, that you can change the software or use pieces of it in new
3.30 +free programs, and that you know you can do these things.
3.31 +
3.32 +  To protect your rights, we need to prevent others from denying you
3.33 +these rights or asking you to surrender the rights.  Therefore, you have
3.34 +certain responsibilities if you distribute copies of the software, or if
3.35 +you modify it: responsibilities to respect the freedom of others.
3.36 +
3.37 +  For example, if you distribute copies of such a program, whether
3.38 +gratis or for a fee, you must pass on to the recipients the same
3.39 +freedoms that you received.  You must make sure that they, too, receive
3.40 +or can get the source code.  And you must show them these terms so they
3.41 +know their rights.
3.42 +
3.43 +  Developers that use the GNU GPL protect your rights with two steps:
3.44 +(1) assert copyright on the software, and (2) offer you this License
3.45 +giving you legal permission to copy, distribute and/or modify it.
3.46 +
3.47 +  For the developers' and authors' protection, the GPL clearly explains
3.48 +that there is no warranty for this free software.  For both users' and
3.49 +authors' sake, the GPL requires that modified versions be marked as
3.50 +changed, so that their problems will not be attributed erroneously to
3.51 +authors of previous versions.
3.52 +
3.53 +  Some devices are designed to deny users access to install or run
3.54 +modified versions of the software inside them, although the manufacturer
3.55 +can do so.  This is fundamentally incompatible with the aim of
3.56 +protecting users' freedom to change the software.  The systematic
3.57 +pattern of such abuse occurs in the area of products for individuals to
3.58 +use, which is precisely where it is most unacceptable.  Therefore, we
3.59 +have designed this version of the GPL to prohibit the practice for those
3.60 +products.  If such problems arise substantially in other domains, we
3.61 +stand ready to extend this provision to those domains in future versions
3.62 +of the GPL, as needed to protect the freedom of users.
3.63 +
3.64 +  Finally, every program is threatened constantly by software patents.
3.65 +States should not allow patents to restrict development and use of
3.66 +software on general-purpose computers, but in those that do, we wish to
3.67 +avoid the special danger that patents applied to a free program could
3.68 +make it effectively proprietary.  To prevent this, the GPL assures that
3.69 +patents cannot be used to render the program non-free.
3.70 +
3.71 +  The precise terms and conditions for copying, distribution and
3.72 +modification follow.
3.73 +
3.74 +                       TERMS AND CONDITIONS
3.75 +
3.76 +  0. Definitions.
3.77 +
3.78 +  "This License" refers to version 3 of the GNU General Public License.
3.79 +
3.80 +  "Copyright" also means copyright-like laws that apply to other kinds of
3.81 +works, such as semiconductor masks.
3.82 +
3.83 +  "The Program" refers to any copyrightable work licensed under this
3.85 +"recipients" may be individuals or organizations.
3.86 +
3.87 +  To "modify" a work means to copy from or adapt all or part of the work
3.88 +in a fashion requiring copyright permission, other than the making of an
3.89 +exact copy.  The resulting work is called a "modified version" of the
3.90 +earlier work or a work "based on" the earlier work.
3.91 +
3.92 +  A "covered work" means either the unmodified Program or a work based
3.93 +on the Program.
3.94 +
3.95 +  To "propagate" a work means to do anything with it that, without
3.96 +permission, would make you directly or secondarily liable for
3.97 +infringement under applicable copyright law, except executing it on a
3.98 +computer or modifying a private copy.  Propagation includes copying,
3.99 +distribution (with or without modification), making available to the
3.100 +public, and in some countries other activities as well.
3.101 +
3.102 +  To "convey" a work means any kind of propagation that enables other
3.103 +parties to make or receive copies.  Mere interaction with a user through
3.104 +a computer network, with no transfer of a copy, is not conveying.
3.105 +
3.106 +  An interactive user interface displays "Appropriate Legal Notices"
3.107 +to the extent that it includes a convenient and prominently visible
3.108 +feature that (1) displays an appropriate copyright notice, and (2)
3.109 +tells the user that there is no warranty for the work (except to the
3.110 +extent that warranties are provided), that licensees may convey the
3.111 +work under this License, and how to view a copy of this License.  If
3.112 +the interface presents a list of user commands or options, such as a
3.113 +menu, a prominent item in the list meets this criterion.
3.114 +
3.115 +  1. Source Code.
3.116 +
3.117 +  The "source code" for a work means the preferred form of the work
3.118 +for making modifications to it.  "Object code" means any non-source
3.119 +form of a work.
3.120 +
3.121 +  A "Standard Interface" means an interface that either is an official
3.122 +standard defined by a recognized standards body, or, in the case of
3.123 +interfaces specified for a particular programming language, one that
3.124 +is widely used among developers working in that language.
3.125 +
3.126 +  The "System Libraries" of an executable work include anything, other
3.127 +than the work as a whole, that (a) is included in the normal form of
3.128 +packaging a Major Component, but which is not part of that Major
3.129 +Component, and (b) serves only to enable use of the work with that
3.130 +Major Component, or to implement a Standard Interface for which an
3.131 +implementation is available to the public in source code form.  A
3.132 +"Major Component", in this context, means a major essential component
3.133 +(kernel, window system, and so on) of the specific operating system
3.134 +(if any) on which the executable work runs, or a compiler used to
3.135 +produce the work, or an object code interpreter used to run it.
3.136 +
3.137 +  The "Corresponding Source" for a work in object code form means all
3.138 +the source code needed to generate, install, and (for an executable
3.139 +work) run the object code and to modify the work, including scripts to
3.140 +control those activities.  However, it does not include the work's
3.141 +System Libraries, or general-purpose tools or generally available free
3.142 +programs which are used unmodified in performing those activities but
3.143 +which are not part of the work.  For example, Corresponding Source
3.144 +includes interface definition files associated with source files for
3.145 +the work, and the source code for shared libraries and dynamically
3.146 +linked subprograms that the work is specifically designed to require,
3.147 +such as by intimate data communication or control flow between those
3.148 +subprograms and other parts of the work.
3.149 +
3.150 +  The Corresponding Source need not include anything that users
3.151 +can regenerate automatically from other parts of the Corresponding
3.152 +Source.
3.153 +
3.154 +  The Corresponding Source for a work in source code form is that
3.155 +same work.
3.156 +
3.157 +  2. Basic Permissions.
3.158 +
3.159 +  All rights granted under this License are granted for the term of
3.160 +copyright on the Program, and are irrevocable provided the stated
3.162 +permission to run the unmodified Program.  The output from running a
3.163 +covered work is covered by this License only if the output, given its
3.164 +content, constitutes a covered work.  This License acknowledges your
3.165 +rights of fair use or other equivalent, as provided by copyright law.
3.166 +
3.167 +  You may make, run and propagate covered works that you do not
3.169 +in force.  You may convey covered works to others for the sole purpose
3.170 +of having them make modifications exclusively for you, or provide you
3.171 +with facilities for running those works, provided that you comply with
3.172 +the terms of this License in conveying all material for which you do
3.173 +not control copyright.  Those thus making or running the covered works
3.174 +for you must do so exclusively on your behalf, under your direction
3.175 +and control, on terms that prohibit them from making any copies of
3.177 +
3.178 +  Conveying under any other circumstances is permitted solely under
3.179 +the conditions stated below.  Sublicensing is not allowed; section 10
3.180 +makes it unnecessary.
3.181 +
3.182 +  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
3.183 +
3.184 +  No covered work shall be deemed part of an effective technological
3.185 +measure under any applicable law fulfilling obligations under article
3.186 +11 of the WIPO copyright treaty adopted on 20 December 1996, or
3.187 +similar laws prohibiting or restricting circumvention of such
3.188 +measures.
3.189 +
3.190 +  When you convey a covered work, you waive any legal power to forbid
3.191 +circumvention of technological measures to the extent such circumvention
3.192 +is effected by exercising rights under this License with respect to
3.193 +the covered work, and you disclaim any intention to limit operation or
3.194 +modification of the work as a means of enforcing, against the work's
3.195 +users, your or third parties' legal rights to forbid circumvention of
3.196 +technological measures.
3.197 +
3.198 +  4. Conveying Verbatim Copies.
3.199 +
3.200 +  You may convey verbatim copies of the Program's source code as you
3.201 +receive it, in any medium, provided that you conspicuously and
3.202 +appropriately publish on each copy an appropriate copyright notice;
3.203 +keep intact all notices stating that this License and any
3.204 +non-permissive terms added in accord with section 7 apply to the code;
3.205 +keep intact all notices of the absence of any warranty; and give all
3.206 +recipients a copy of this License along with the Program.
3.207 +
3.208 +  You may charge any price or no price for each copy that you convey,
3.209 +and you may offer support or warranty protection for a fee.
3.210 +
3.211 +  5. Conveying Modified Source Versions.
3.212 +
3.213 +  You may convey a work based on the Program, or the modifications to
3.214 +produce it from the Program, in the form of source code under the
3.215 +terms of section 4, provided that you also meet all of these conditions:
3.216 +
3.217 +    a) The work must carry prominent notices stating that you modified
3.218 +    it, and giving a relevant date.
3.219 +
3.220 +    b) The work must carry prominent notices stating that it is
3.221 +    released under this License and any conditions added under section
3.222 +    7.  This requirement modifies the requirement in section 4 to
3.223 +    "keep intact all notices".
3.224 +
3.225 +    c) You must license the entire work, as a whole, under this
3.226 +    License to anyone who comes into possession of a copy.  This
3.227 +    License will therefore apply, along with any applicable section 7
3.228 +    additional terms, to the whole of the work, and all its parts,
3.229 +    regardless of how they are packaged.  This License gives no
3.230 +    permission to license the work in any other way, but it does not
3.231 +    invalidate such permission if you have separately received it.
3.232 +
3.233 +    d) If the work has interactive user interfaces, each must display
3.234 +    Appropriate Legal Notices; however, if the Program has interactive
3.235 +    interfaces that do not display Appropriate Legal Notices, your
3.236 +    work need not make them do so.
3.237 +
3.238 +  A compilation of a covered work with other separate and independent
3.239 +works, which are not by their nature extensions of the covered work,
3.240 +and which are not combined with it such as to form a larger program,
3.241 +in or on a volume of a storage or distribution medium, is called an
3.242 +"aggregate" if the compilation and its resulting copyright are not
3.243 +used to limit the access or legal rights of the compilation's users
3.244 +beyond what the individual works permit.  Inclusion of a covered work
3.245 +in an aggregate does not cause this License to apply to the other
3.246 +parts of the aggregate.
3.247 +
3.248 +  6. Conveying Non-Source Forms.
3.249 +
3.250 +  You may convey a covered work in object code form under the terms
3.251 +of sections 4 and 5, provided that you also convey the
3.253 +in one of these ways:
3.254 +
3.255 +    a) Convey the object code in, or embodied in, a physical product
3.256 +    (including a physical distribution medium), accompanied by the
3.257 +    Corresponding Source fixed on a durable physical medium
3.258 +    customarily used for software interchange.
3.259 +
3.260 +    b) Convey the object code in, or embodied in, a physical product
3.261 +    (including a physical distribution medium), accompanied by a
3.262 +    written offer, valid for at least three years and valid for as
3.263 +    long as you offer spare parts or customer support for that product
3.264 +    model, to give anyone who possesses the object code either (1) a
3.265 +    copy of the Corresponding Source for all the software in the
3.266 +    product that is covered by this License, on a durable physical
3.267 +    medium customarily used for software interchange, for a price no
3.268 +    more than your reasonable cost of physically performing this
3.270 +    Corresponding Source from a network server at no charge.
3.271 +
3.272 +    c) Convey individual copies of the object code with a copy of the
3.273 +    written offer to provide the Corresponding Source.  This
3.274 +    alternative is allowed only occasionally and noncommercially, and
3.275 +    only if you received the object code with such an offer, in accord
3.276 +    with subsection 6b.
3.277 +
3.278 +    d) Convey the object code by offering access from a designated
3.279 +    place (gratis or for a charge), and offer equivalent access to the
3.280 +    Corresponding Source in the same way through the same place at no
3.281 +    further charge.  You need not require recipients to copy the
3.282 +    Corresponding Source along with the object code.  If the place to
3.283 +    copy the object code is a network server, the Corresponding Source
3.284 +    may be on a different server (operated by you or a third party)
3.285 +    that supports equivalent copying facilities, provided you maintain
3.286 +    clear directions next to the object code saying where to find the
3.287 +    Corresponding Source.  Regardless of what server hosts the
3.288 +    Corresponding Source, you remain obligated to ensure that it is
3.289 +    available for as long as needed to satisfy these requirements.
3.290 +
3.291 +    e) Convey the object code using peer-to-peer transmission, provided
3.292 +    you inform other peers where the object code and Corresponding
3.293 +    Source of the work are being offered to the general public at no
3.294 +    charge under subsection 6d.
3.295 +
3.296 +  A separable portion of the object code, whose source code is excluded
3.297 +from the Corresponding Source as a System Library, need not be
3.298 +included in conveying the object code work.
3.299 +
3.300 +  A "User Product" is either (1) a "consumer product", which means any
3.301 +tangible personal property which is normally used for personal, family,
3.302 +or household purposes, or (2) anything designed or sold for incorporation
3.303 +into a dwelling.  In determining whether a product is a consumer product,
3.304 +doubtful cases shall be resolved in favor of coverage.  For a particular
3.305 +product received by a particular user, "normally used" refers to a
3.306 +typical or common use of that class of product, regardless of the status
3.307 +of the particular user or of the way in which the particular user
3.308 +actually uses, or expects or is expected to use, the product.  A product
3.309 +is a consumer product regardless of whether the product has substantial
3.310 +commercial, industrial or non-consumer uses, unless such uses represent
3.311 +the only significant mode of use of the product.
3.312 +
3.313 +  "Installation Information" for a User Product means any methods,
3.314 +procedures, authorization keys, or other information required to install
3.315 +and execute modified versions of a covered work in that User Product from
3.316 +a modified version of its Corresponding Source.  The information must
3.317 +suffice to ensure that the continued functioning of the modified object
3.318 +code is in no case prevented or interfered with solely because
3.320 +
3.321 +  If you convey an object code work under this section in, or with, or
3.322 +specifically for use in, a User Product, and the conveying occurs as
3.323 +part of a transaction in which the right of possession and use of the
3.324 +User Product is transferred to the recipient in perpetuity or for a
3.325 +fixed term (regardless of how the transaction is characterized), the
3.326 +Corresponding Source conveyed under this section must be accompanied
3.327 +by the Installation Information.  But this requirement does not apply
3.328 +if neither you nor any third party retains the ability to install
3.329 +modified object code on the User Product (for example, the work has
3.330 +been installed in ROM).
3.331 +
3.332 +  The requirement to provide Installation Information does not include a
3.333 +requirement to continue to provide support service, warranty, or updates
3.334 +for a work that has been modified or installed by the recipient, or for
3.335 +the User Product in which it has been modified or installed.  Access to a
3.336 +network may be denied when the modification itself materially and
3.337 +adversely affects the operation of the network or violates the rules and
3.338 +protocols for communication across the network.
3.339 +
3.340 +  Corresponding Source conveyed, and Installation Information provided,
3.341 +in accord with this section must be in a format that is publicly
3.342 +documented (and with an implementation available to the public in
3.343 +source code form), and must require no special password or key for
3.345 +
3.347 +
3.348 +  "Additional permissions" are terms that supplement the terms of this
3.349 +License by making exceptions from one or more of its conditions.
3.350 +Additional permissions that are applicable to the entire Program shall
3.351 +be treated as though they were included in this License, to the extent
3.352 +that they are valid under applicable law.  If additional permissions
3.353 +apply only to part of the Program, that part may be used separately
3.354 +under those permissions, but the entire Program remains governed by
3.356 +
3.357 +  When you convey a copy of a covered work, you may at your option
3.358 +remove any additional permissions from that copy, or from any part of
3.359 +it.  (Additional permissions may be written to require their own
3.360 +removal in certain cases when you modify the work.)  You may place
3.361 +additional permissions on material, added by you to a covered work,
3.362 +for which you have or can give appropriate copyright permission.
3.363 +
3.364 +  Notwithstanding any other provision of this License, for material you
3.365 +add to a covered work, you may (if authorized by the copyright holders of
3.366 +that material) supplement the terms of this License with terms:
3.367 +
3.368 +    a) Disclaiming warranty or limiting liability differently from the
3.369 +    terms of sections 15 and 16 of this License; or
3.370 +
3.371 +    b) Requiring preservation of specified reasonable legal notices or
3.372 +    author attributions in that material or in the Appropriate Legal
3.373 +    Notices displayed by works containing it; or
3.374 +
3.375 +    c) Prohibiting misrepresentation of the origin of that material, or
3.376 +    requiring that modified versions of such material be marked in
3.377 +    reasonable ways as different from the original version; or
3.378 +
3.379 +    d) Limiting the use for publicity purposes of names of licensors or
3.380 +    authors of the material; or
3.381 +
3.382 +    e) Declining to grant rights under trademark law for use of some
3.384 +
3.385 +    f) Requiring indemnification of licensors and authors of that
3.386 +    material by anyone who conveys the material (or modified versions of
3.387 +    it) with contractual assumptions of liability to the recipient, for
3.388 +    any liability that these contractual assumptions directly impose on
3.389 +    those licensors and authors.
3.390 +
3.391 +  All other non-permissive additional terms are considered "further
3.392 +restrictions" within the meaning of section 10.  If the Program as you
3.393 +received it, or any part of it, contains a notice stating that it is
3.394 +governed by this License along with a term that is a further
3.395 +restriction, you may remove that term.  If a license document contains
3.396 +a further restriction but permits relicensing or conveying under this
3.397 +License, you may add to a covered work material governed by the terms
3.398 +of that license document, provided that the further restriction does
3.399 +not survive such relicensing or conveying.
3.400 +
3.401 +  If you add terms to a covered work in accord with this section, you
3.402 +must place, in the relevant source files, a statement of the
3.403 +additional terms that apply to those files, or a notice indicating
3.404 +where to find the applicable terms.
3.405 +
3.406 +  Additional terms, permissive or non-permissive, may be stated in the
3.407 +form of a separately written license, or stated as exceptions;
3.408 +the above requirements apply either way.
3.409 +
3.410 +  8. Termination.
3.411 +
3.412 +  You may not propagate or modify a covered work except as expressly
3.413 +provided under this License.  Any attempt otherwise to propagate or
3.414 +modify it is void, and will automatically terminate your rights under
3.416 +paragraph of section 11).
3.417 +
3.418 +  However, if you cease all violation of this License, then your
3.420 +provisionally, unless and until the copyright holder explicitly and
3.422 +holder fails to notify you of the violation by some reasonable means
3.423 +prior to 60 days after the cessation.
3.424 +
3.426 +reinstated permanently if the copyright holder notifies you of the
3.427 +violation by some reasonable means, this is the first time you have
3.428 +received notice of violation of this License (for any work) from that
3.429 +copyright holder, and you cure the violation prior to 30 days after
3.430 +your receipt of the notice.
3.431 +
3.432 +  Termination of your rights under this section does not terminate the
3.433 +licenses of parties who have received copies or rights from you under
3.434 +this License.  If your rights have been terminated and not permanently
3.435 +reinstated, you do not qualify to receive new licenses for the same
3.436 +material under section 10.
3.437 +
3.438 +  9. Acceptance Not Required for Having Copies.
3.439 +
3.440 +  You are not required to accept this License in order to receive or
3.441 +run a copy of the Program.  Ancillary propagation of a covered work
3.442 +occurring solely as a consequence of using peer-to-peer transmission
3.443 +to receive a copy likewise does not require acceptance.  However,
3.444 +nothing other than this License grants you permission to propagate or
3.445 +modify any covered work.  These actions infringe copyright if you do
3.446 +not accept this License.  Therefore, by modifying or propagating a
3.447 +covered work, you indicate your acceptance of this License to do so.
3.448 +
3.449 +  10. Automatic Licensing of Downstream Recipients.
3.450 +
3.451 +  Each time you convey a covered work, the recipient automatically
3.452 +receives a license from the original licensors, to run, modify and
3.453 +propagate that work, subject to this License.  You are not responsible
3.454 +for enforcing compliance by third parties with this License.
3.455 +
3.456 +  An "entity transaction" is a transaction transferring control of an
3.457 +organization, or substantially all assets of one, or subdividing an
3.458 +organization, or merging organizations.  If propagation of a covered
3.459 +work results from an entity transaction, each party to that
3.460 +transaction who receives a copy of the work also receives whatever
3.461 +licenses to the work the party's predecessor in interest had or could
3.462 +give under the previous paragraph, plus a right to possession of the
3.463 +Corresponding Source of the work from the predecessor in interest, if
3.464 +the predecessor has it or can get it with reasonable efforts.
3.465 +
3.466 +  You may not impose any further restrictions on the exercise of the
3.467 +rights granted or affirmed under this License.  For example, you may
3.468 +not impose a license fee, royalty, or other charge for exercise of
3.469 +rights granted under this License, and you may not initiate litigation
3.470 +(including a cross-claim or counterclaim in a lawsuit) alleging that
3.471 +any patent claim is infringed by making, using, selling, offering for
3.472 +sale, or importing the Program or any portion of it.
3.473 +
3.474 +  11. Patents.
3.475 +
3.476 +  A "contributor" is a copyright holder who authorizes use under this
3.477 +License of the Program or a work on which the Program is based.  The
3.478 +work thus licensed is called the contributor's "contributor version".
3.479 +
3.480 +  A contributor's "essential patent claims" are all patent claims
3.481 +owned or controlled by the contributor, whether already acquired or
3.482 +hereafter acquired, that would be infringed by some manner, permitted
3.483 +by this License, of making, using, or selling its contributor version,
3.484 +but do not include claims that would be infringed only as a
3.485 +consequence of further modification of the contributor version.  For
3.486 +purposes of this definition, "control" includes the right to grant
3.487 +patent sublicenses in a manner consistent with the requirements of
3.489 +
3.490 +  Each contributor grants you a non-exclusive, worldwide, royalty-free
3.491 +patent license under the contributor's essential patent claims, to
3.492 +make, use, sell, offer for sale, import and otherwise run, modify and
3.493 +propagate the contents of its contributor version.
3.494 +
3.495 +  In the following three paragraphs, a "patent license" is any express
3.496 +agreement or commitment, however denominated, not to enforce a patent
3.497 +(such as an express permission to practice a patent or covenant not to
3.498 +sue for patent infringement).  To "grant" such a patent license to a
3.499 +party means to make such an agreement or commitment not to enforce a
3.500 +patent against the party.
3.501 +
3.502 +  If you convey a covered work, knowingly relying on a patent license,
3.503 +and the Corresponding Source of the work is not available for anyone
3.504 +to copy, free of charge and under the terms of this License, through a
3.505 +publicly available network server or other readily accessible means,
3.506 +then you must either (1) cause the Corresponding Source to be so
3.507 +available, or (2) arrange to deprive yourself of the benefit of the
3.508 +patent license for this particular work, or (3) arrange, in a manner
3.509 +consistent with the requirements of this License, to extend the patent
3.510 +license to downstream recipients.  "Knowingly relying" means you have
3.511 +actual knowledge that, but for the patent license, your conveying the
3.512 +covered work in a country, or your recipient's use of the covered work
3.513 +in a country, would infringe one or more identifiable patents in that
3.514 +country that you have reason to believe are valid.
3.515 +
3.516 +  If, pursuant to or in connection with a single transaction or
3.517 +arrangement, you convey, or propagate by procuring conveyance of, a
3.518 +covered work, and grant a patent license to some of the parties
3.519 +receiving the covered work authorizing them to use, propagate, modify
3.520 +or convey a specific copy of the covered work, then the patent license
3.521 +you grant is automatically extended to all recipients of the covered
3.522 +work and works based on it.
3.523 +
3.524 +  A patent license is "discriminatory" if it does not include within
3.525 +the scope of its coverage, prohibits the exercise of, or is
3.526 +conditioned on the non-exercise of one or more of the rights that are
3.527 +specifically granted under this License.  You may not convey a covered
3.528 +work if you are a party to an arrangement with a third party that is
3.529 +in the business of distributing software, under which you make payment
3.530 +to the third party based on the extent of your activity of conveying
3.531 +the work, and under which the third party grants, to any of the
3.532 +parties who would receive the covered work from you, a discriminatory
3.533 +patent license (a) in connection with copies of the covered work
3.534 +conveyed by you (or copies made from those copies), or (b) primarily
3.535 +for and in connection with specific products or compilations that
3.536 +contain the covered work, unless you entered into that arrangement,
3.537 +or that patent license was granted, prior to 28 March 2007.
3.538 +
3.539 +  Nothing in this License shall be construed as excluding or limiting
3.540 +any implied license or other defenses to infringement that may
3.541 +otherwise be available to you under applicable patent law.
3.542 +
3.543 +  12. No Surrender of Others' Freedom.
3.544 +
3.545 +  If conditions are imposed on you (whether by court order, agreement or
3.546 +otherwise) that contradict the conditions of this License, they do not
3.547 +excuse you from the conditions of this License.  If you cannot convey a
3.548 +covered work so as to satisfy simultaneously your obligations under this
3.549 +License and any other pertinent obligations, then as a consequence you may
3.550 +not convey it at all.  For example, if you agree to terms that obligate you
3.551 +to collect a royalty for further conveying from those to whom you convey
3.552 +the Program, the only way you could satisfy both those terms and this
3.553 +License would be to refrain entirely from conveying the Program.
3.554 +
3.555 +  13. Use with the GNU Affero General Public License.
3.556 +
3.557 +  Notwithstanding any other provision of this License, you have
3.558 +permission to link or combine any covered work with a work licensed
3.559 +under version 3 of the GNU Affero General Public License into a single
3.560 +combined work, and to convey the resulting work.  The terms of this
3.561 +License will continue to apply to the part which is the covered work,
3.562 +but the special requirements of the GNU Affero General Public License,
3.563 +section 13, concerning interaction through a network will apply to the
3.564 +combination as such.
3.565 +
3.566 +  14. Revised Versions of this License.
3.567 +
3.568 +  The Free Software Foundation may publish revised and/or new versions of
3.569 +the GNU General Public License from time to time.  Such new versions will
3.570 +be similar in spirit to the present version, but may differ in detail to
3.571 +address new problems or concerns.
3.572 +
3.573 +  Each version is given a distinguishing version number.  If the
3.574 +Program specifies that a certain numbered version of the GNU General
3.575 +Public License "or any later version" applies to it, you have the
3.576 +option of following the terms and conditions either of that numbered
3.577 +version or of any later version published by the Free Software
3.578 +Foundation.  If the Program does not specify a version number of the
3.579 +GNU General Public License, you may choose any version ever published
3.580 +by the Free Software Foundation.
3.581 +
3.582 +  If the Program specifies that a proxy can decide which future
3.583 +versions of the GNU General Public License can be used, that proxy's
3.584 +public statement of acceptance of a version permanently authorizes you
3.585 +to choose that version for the Program.
3.586 +
3.588 +permissions.  However, no additional obligations are imposed on any
3.590 +later version.
3.591 +
3.592 +  15. Disclaimer of Warranty.
3.593 +
3.594 +  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
3.595 +APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
3.596 +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
3.597 +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
3.598 +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
3.599 +PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
3.600 +IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
3.601 +ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

3.604 +
3.605 +  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
3.606 +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
3.607 +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
3.608 +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
3.609 +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
3.610 +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
3.611 +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),

3.615 +  17. Interpretation of Sections 15 and 16.
3.616 +
3.617 +  If the disclaimer of warranty and limitation of liability provided
3.618 +above cannot be given local legal effect according to their terms,
3.619 +reviewing courts shall apply local law that most closely approximates
3.620 +an absolute waiver of all civil liability in connection with the
3.621 +Program, unless a warranty or assumption of liability accompanies a
3.622 +copy of the Program in return for a fee.
3.623 +
3.624 +                     END OF TERMS AND CONDITIONS
3.625 +
3.626 +            How to Apply These Terms to Your New Programs
3.627 +
3.628 +  If you develop a new program, and you want it to be of the greatest
3.629 +possible use to the public, the best way to achieve this is to make it
3.630 +free software which everyone can redistribute and change under these terms.
3.631 +
3.632 +  To do so, attach the following notices to the program.  It is safest
3.633 +to attach them to the start of each source file to most effectively
3.634 +state the exclusion of warranty; and each file should have at least
3.635 +the "copyright" line and a pointer to where the full notice is found.
3.636 +
3.637 +    <one line to give the program's name and a brief idea of what it does.>
3.638 +    Copyright (C) <year>  <name of author>
3.639 +
3.640 +    This program is free software: you can redistribute it and/or modify
3.642 +    the Free Software Foundation, either version 3 of the License, or
3.643 +    (at your option) any later version.
3.644 +
3.645 +    This program is distributed in the hope that it will be useful,
3.646 +    but WITHOUT ANY WARRANTY; without even the implied warranty of
3.647 +    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
3.648 +    GNU General Public License for more details.
3.649 +
3.650 +    You should have received a copy of the GNU General Public License
3.651 +    along with this program.  If not, see <http://www.gnu.org/licenses/>.
3.652 +
3.653 +Also add information on how to contact you by electronic and paper mail.
3.654 +
3.655 +  If the program does terminal interaction, make it output a short
3.656 +notice like this when it starts in an interactive mode:
3.657 +
3.658 +    <program>  Copyright (C) <year>  <name of author>
3.659 +    This program comes with ABSOLUTELY NO WARRANTY; for details type show w'.
3.660 +    This is free software, and you are welcome to redistribute it
3.661 +    under certain conditions; type show c' for details.
3.662 +
3.663 +The hypothetical commands show w' and show c' should show the appropriate
3.664 +parts of the General Public License.  Of course, your program's commands
3.665 +might be different; for a GUI interface, you would use an "about box".
3.666 +
3.667 +  You should also get your employer (if you work as a programmer) or school,
3.668 +if any, to sign a "copyright disclaimer" for the program, if necessary.
3.671 +
3.672 +  The GNU General Public License does not permit incorporating your program
3.673 +into proprietary programs.  If your program is a subroutine library, you
3.674 +may consider it more useful to permit linking proprietary applications with
3.675 +the library.  If this is what you want to do, use the GNU Lesser General
3.677 +<http://www.gnu.org/philosophy/why-not-lgpl.html>.
