    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
    2.36 +your programs, too.
    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.

    2.93 +\begin{enumerate}
    2.94 +
    2.95 +\addtocounter{enumi}{-1}
    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
   2.182 +conditions are met.  This License explicitly affirms your unlimited
   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
   2.189 +convey, without conditions so long as your license otherwise remains
   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
   2.197 +your copyrighted material outside their relationship with you.
   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
   2.273 +machine-readable Corresponding Source under the terms of this License,
   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
   2.290 +  conveying of source, or (2) access to copy the
   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
   2.341 +modification has been made.
   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
   2.366 +unpacking, reading or copying.
   2.367 +
   2.368 +\item Additional Terms.
   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
   2.377 +this License without regard to the additional permissions.
   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
   2.405 +  trade names, trademarks, or service marks; or
   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
   2.438 +this License (including any patent licenses granted under the third
   2.439 +paragraph of section 11).
   2.440 +
   2.441 +However, if you cease all violation of this License, then your
   2.442 +license from a particular copyright holder is reinstated (a)
   2.443 +provisionally, unless and until the copyright holder explicitly and
   2.444 +finally terminates your license, and (b) permanently, if the copyright
   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 +
   2.448 +Moreover, your license from a particular copyright holder is
   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
   2.511 +this License.
   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 +
   2.610 +Later license versions may give you additional or different
   2.611 +permissions.  However, no additional obligations are imposed on any
   2.612 +author or copyright holder as a result of your choosing to follow a
   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.

   2.677 +
   2.678 +This program is distributed in the hope that it will be useful,
   2.679 +but WITHOUT ANY WARRANTY; without even the implied warranty of
   2.680 +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
   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

   2.699 +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
   2.717 +the GNU Lesser General Public License instead of this License.  But
   2.718 +first, please read \texttt{http://www.gnu.org/philosophy/why-not-lgpl.html}.

     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
    3.23 +your programs, too.
    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
    3.84 +License.  Each licensee is addressed as "you".  "Licensees" and
    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
   3.161 +conditions are met.  This License explicitly affirms your unlimited
   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
   3.168 +convey, without conditions so long as your license otherwise remains
   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
   3.176 +your copyrighted material outside their relationship with you.
   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
   3.252 +machine-readable Corresponding Source under the terms of this License,
   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
   3.269 +    conveying of source, or (2) access to copy the
   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
   3.319 +modification has been made.
   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
   3.344 +unpacking, reading or copying.
   3.345 +
   3.346 +  7. Additional Terms.
   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
   3.355 +this License without regard to the additional permissions.
   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
   3.383 +    trade names, trademarks, or service marks; or
   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
   3.415 +this License (including any patent licenses granted under the third
   3.416 +paragraph of section 11).
   3.417 +
   3.418 +  However, if you cease all violation of this License, then your
   3.419 +license from a particular copyright holder is reinstated (a)
   3.420 +provisionally, unless and until the copyright holder explicitly and
   3.421 +finally terminates your license, and (b) permanently, if the copyright
   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 +
   3.425 +  Moreover, your license from a particular copyright holder is
   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
   3.488 +this License.
   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 +
   3.587 +  Later license versions may give you additional or different
   3.588 +permissions.  However, no additional obligations are imposed on any
   3.589 +author or copyright holder as a result of your choosing to follow a
   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.
   3.602 +
   3.603 +  16. Limitation of Liability.
   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),
   3.612 +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
   3.613 +SUCH DAMAGES.
   3.614 +
   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
   3.641 +    it under the terms of the GNU General Public License as published by
   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.
   3.669 +For more information on this, and how to apply and follow the GNU GPL, see
   3.670 +<http://www.gnu.org/licenses/>.
   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
   3.676 +Public License instead of this License.  But first, please read
   3.677 +<http://www.gnu.org/philosophy/why-not-lgpl.html>.
