     1.5 +                       Version 3, 29 June 2007
     1.6 +
     1.7 + Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
     1.8 + Everyone is permitted to copy and distribute verbatim copies
     1.9 + of this license document, but changing it is not allowed.
    1.10 +
    1.11 +                            Preamble
    1.12 +
    1.13 +  The GNU General Public License is a free, copyleft license for
    1.14 +software and other kinds of works.
    1.15 +
    1.16 +  The licenses for most software and other practical works are designed
    1.17 +to take away your freedom to share and change the works.  By contrast,
    1.18 +the GNU General Public License is intended to guarantee your freedom to
    1.19 +share and change all versions of a program--to make sure it remains free
    1.20 +software for all its users.  We, the Free Software Foundation, use the
    1.21 +GNU General Public License for most of our software; it applies also to
    1.22 +any other work released this way by its authors.  You can apply it to
    1.23 +your programs, too.
    1.24 +
    1.25 +  When we speak of free software, we are referring to freedom, not
    1.26 +price.  Our General Public Licenses are designed to make sure that you
    1.27 +have the freedom to distribute copies of free software (and charge for
    1.28 +them if you wish), that you receive source code or can get it if you
    1.29 +want it, that you can change the software or use pieces of it in new
    1.30 +free programs, and that you know you can do these things.
    1.31 +
    1.32 +  To protect your rights, we need to prevent others from denying you
    1.33 +these rights or asking you to surrender the rights.  Therefore, you have
    1.34 +certain responsibilities if you distribute copies of the software, or if
    1.35 +you modify it: responsibilities to respect the freedom of others.
    1.36 +
    1.37 +  For example, if you distribute copies of such a program, whether
    1.38 +gratis or for a fee, you must pass on to the recipients the same
    1.39 +freedoms that you received.  You must make sure that they, too, receive
    1.40 +or can get the source code.  And you must show them these terms so they
    1.41 +know their rights.
    1.42 +
    1.43 +  Developers that use the GNU GPL protect your rights with two steps:
    1.44 +(1) assert copyright on the software, and (2) offer you this License
    1.45 +giving you legal permission to copy, distribute and/or modify it.
    1.46 +
    1.47 +  For the developers' and authors' protection, the GPL clearly explains
    1.48 +that there is no warranty for this free software.  For both users' and
    1.49 +authors' sake, the GPL requires that modified versions be marked as
    1.50 +changed, so that their problems will not be attributed erroneously to
    1.51 +authors of previous versions.
    1.52 +
    1.53 +  Some devices are designed to deny users access to install or run
    1.54 +modified versions of the software inside them, although the manufacturer
    1.55 +can do so.  This is fundamentally incompatible with the aim of
    1.56 +protecting users' freedom to change the software.  The systematic
    1.57 +pattern of such abuse occurs in the area of products for individuals to
    1.58 +use, which is precisely where it is most unacceptable.  Therefore, we
    1.59 +have designed this version of the GPL to prohibit the practice for those
    1.60 +products.  If such problems arise substantially in other domains, we
    1.61 +stand ready to extend this provision to those domains in future versions
    1.62 +of the GPL, as needed to protect the freedom of users.
    1.63 +
    1.64 +  Finally, every program is threatened constantly by software patents.
    1.65 +States should not allow patents to restrict development and use of
    1.66 +software on general-purpose computers, but in those that do, we wish to
    1.67 +avoid the special danger that patents applied to a free program could
    1.68 +make it effectively proprietary.  To prevent this, the GPL assures that
    1.69 +patents cannot be used to render the program non-free.
    1.70 +
    1.71 +  The precise terms and conditions for copying, distribution and
    1.72 +modification follow.
    1.73 +
    1.74 +                       TERMS AND CONDITIONS
    1.75 +
    1.76 +  0. Definitions.
    1.77 +
    1.78 +  "This License" refers to version 3 of the GNU General Public License.
    1.79 +
    1.80 +  "Copyright" also means copyright-like laws that apply to other kinds of
    1.81 +works, such as semiconductor masks.
    1.82 +
    1.83 +  "The Program" refers to any copyrightable work licensed under this
    1.84 +License.  Each licensee is addressed as "you".  "Licensees" and
    1.85 +"recipients" may be individuals or organizations.
    1.86 +
    1.87 +  To "modify" a work means to copy from or adapt all or part of the work
    1.88 +in a fashion requiring copyright permission, other than the making of an
    1.89 +exact copy.  The resulting work is called a "modified version" of the
    1.90 +earlier work or a work "based on" the earlier work.
    1.91 +
    1.92 +  A "covered work" means either the unmodified Program or a work based
    1.93 +on the Program.
    1.94 +
    1.95 +  To "propagate" a work means to do anything with it that, without
    1.96 +permission, would make you directly or secondarily liable for
    1.97 +infringement under applicable copyright law, except executing it on a
    1.98 +computer or modifying a private copy.  Propagation includes copying,
    1.99 +distribution (with or without modification), making available to the
   1.100 +public, and in some countries other activities as well.
   1.101 +
   1.102 +  To "convey" a work means any kind of propagation that enables other
   1.103 +parties to make or receive copies.  Mere interaction with a user through
   1.104 +a computer network, with no transfer of a copy, is not conveying.
   1.105 +
   1.106 +  An interactive user interface displays "Appropriate Legal Notices"
   1.107 +to the extent that it includes a convenient and prominently visible
   1.108 +feature that (1) displays an appropriate copyright notice, and (2)
   1.109 +tells the user that there is no warranty for the work (except to the
   1.110 +extent that warranties are provided), that licensees may convey the
   1.111 +work under this License, and how to view a copy of this License.  If
   1.112 +the interface presents a list of user commands or options, such as a
   1.113 +menu, a prominent item in the list meets this criterion.
   1.114 +
   1.115 +  1. Source Code.
   1.116 +
   1.117 +  The "source code" for a work means the preferred form of the work
   1.118 +for making modifications to it.  "Object code" means any non-source
   1.119 +form of a work.
   1.120 +
   1.121 +  A "Standard Interface" means an interface that either is an official
   1.122 +standard defined by a recognized standards body, or, in the case of
   1.123 +interfaces specified for a particular programming language, one that
   1.124 +is widely used among developers working in that language.
   1.125 +
   1.126 +  The "System Libraries" of an executable work include anything, other
   1.127 +than the work as a whole, that (a) is included in the normal form of
   1.128 +packaging a Major Component, but which is not part of that Major
   1.129 +Component, and (b) serves only to enable use of the work with that
   1.130 +Major Component, or to implement a Standard Interface for which an
   1.131 +implementation is available to the public in source code form.  A
   1.132 +"Major Component", in this context, means a major essential component
   1.133 +(kernel, window system, and so on) of the specific operating system
   1.134 +(if any) on which the executable work runs, or a compiler used to
   1.135 +produce the work, or an object code interpreter used to run it.
   1.136 +
   1.137 +  The "Corresponding Source" for a work in object code form means all
   1.138 +the source code needed to generate, install, and (for an executable
   1.139 +work) run the object code and to modify the work, including scripts to
   1.140 +control those activities.  However, it does not include the work's
   1.141 +System Libraries, or general-purpose tools or generally available free
   1.142 +programs which are used unmodified in performing those activities but
   1.143 +which are not part of the work.  For example, Corresponding Source
   1.144 +includes interface definition files associated with source files for
   1.145 +the work, and the source code for shared libraries and dynamically
   1.146 +linked subprograms that the work is specifically designed to require,
   1.147 +such as by intimate data communication or control flow between those
   1.148 +subprograms and other parts of the work.
   1.149 +
   1.150 +  The Corresponding Source need not include anything that users
   1.151 +can regenerate automatically from other parts of the Corresponding
   1.152 +Source.
   1.153 +
   1.154 +  The Corresponding Source for a work in source code form is that
   1.155 +same work.
   1.156 +
   1.157 +  2. Basic Permissions.
   1.158 +
   1.159 +  All rights granted under this License are granted for the term of
   1.160 +copyright on the Program, and are irrevocable provided the stated
   1.161 +conditions are met.  This License explicitly affirms your unlimited
   1.162 +permission to run the unmodified Program.  The output from running a
   1.163 +covered work is covered by this License only if the output, given its
   1.164 +content, constitutes a covered work.  This License acknowledges your
   1.165 +rights of fair use or other equivalent, as provided by copyright law.
   1.166 +
   1.167 +  You may make, run and propagate covered works that you do not
   1.168 +convey, without conditions so long as your license otherwise remains
   1.169 +in force.  You may convey covered works to others for the sole purpose
   1.170 +of having them make modifications exclusively for you, or provide you
   1.171 +with facilities for running those works, provided that you comply with
   1.172 +the terms of this License in conveying all material for which you do
   1.173 +not control copyright.  Those thus making or running the covered works
   1.174 +for you must do so exclusively on your behalf, under your direction
   1.175 +and control, on terms that prohibit them from making any copies of
   1.176 +your copyrighted material outside their relationship with you.
   1.177 +
   1.178 +  Conveying under any other circumstances is permitted solely under
   1.179 +the conditions stated below.  Sublicensing is not allowed; section 10
   1.180 +makes it unnecessary.
   1.181 +
   1.182 +  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
   1.183 +
   1.184 +  No covered work shall be deemed part of an effective technological
   1.185 +measure under any applicable law fulfilling obligations under article
   1.186 +11 of the WIPO copyright treaty adopted on 20 December 1996, or
   1.187 +similar laws prohibiting or restricting circumvention of such
   1.188 +measures.
   1.189 +
   1.190 +  When you convey a covered work, you waive any legal power to forbid
   1.191 +circumvention of technological measures to the extent such circumvention
   1.192 +is effected by exercising rights under this License with respect to
   1.193 +the covered work, and you disclaim any intention to limit operation or
   1.194 +modification of the work as a means of enforcing, against the work's
   1.195 +users, your or third parties' legal rights to forbid circumvention of
   1.196 +technological measures.
   1.197 +
   1.198 +  4. Conveying Verbatim Copies.
   1.199 +
   1.200 +  You may convey verbatim copies of the Program's source code as you
   1.201 +receive it, in any medium, provided that you conspicuously and
   1.202 +appropriately publish on each copy an appropriate copyright notice;
   1.203 +keep intact all notices stating that this License and any
   1.204 +non-permissive terms added in accord with section 7 apply to the code;
   1.205 +keep intact all notices of the absence of any warranty; and give all
   1.206 +recipients a copy of this License along with the Program.
   1.207 +
   1.208 +  You may charge any price or no price for each copy that you convey,
   1.209 +and you may offer support or warranty protection for a fee.
   1.210 +
   1.211 +  5. Conveying Modified Source Versions.
   1.212 +
   1.213 +  You may convey a work based on the Program, or the modifications to
   1.214 +produce it from the Program, in the form of source code under the
   1.215 +terms of section 4, provided that you also meet all of these conditions:
   1.216 +
   1.217 +    a) The work must carry prominent notices stating that you modified
   1.218 +    it, and giving a relevant date.
   1.219 +
   1.220 +    b) The work must carry prominent notices stating that it is
   1.221 +    released under this License and any conditions added under section
   1.222 +    7.  This requirement modifies the requirement in section 4 to
   1.223 +    "keep intact all notices".
   1.224 +
   1.225 +    c) You must license the entire work, as a whole, under this
   1.226 +    License to anyone who comes into possession of a copy.  This
   1.227 +    License will therefore apply, along with any applicable section 7
   1.228 +    additional terms, to the whole of the work, and all its parts,
   1.229 +    regardless of how they are packaged.  This License gives no
   1.230 +    permission to license the work in any other way, but it does not
   1.231 +    invalidate such permission if you have separately received it.
   1.232 +
   1.233 +    d) If the work has interactive user interfaces, each must display
   1.234 +    Appropriate Legal Notices; however, if the Program has interactive
   1.235 +    interfaces that do not display Appropriate Legal Notices, your
   1.236 +    work need not make them do so.
   1.237 +
   1.238 +  A compilation of a covered work with other separate and independent
   1.239 +works, which are not by their nature extensions of the covered work,
   1.240 +and which are not combined with it such as to form a larger program,
   1.241 +in or on a volume of a storage or distribution medium, is called an
   1.242 +"aggregate" if the compilation and its resulting copyright are not
   1.243 +used to limit the access or legal rights of the compilation's users
   1.244 +beyond what the individual works permit.  Inclusion of a covered work
   1.245 +in an aggregate does not cause this License to apply to the other
   1.246 +parts of the aggregate.
   1.247 +
   1.248 +  6. Conveying Non-Source Forms.
   1.249 +
   1.250 +  You may convey a covered work in object code form under the terms
   1.251 +of sections 4 and 5, provided that you also convey the
   1.252 +machine-readable Corresponding Source under the terms of this License,
   1.253 +in one of these ways:
   1.254 +
   1.255 +    a) Convey the object code in, or embodied in, a physical product
   1.256 +    (including a physical distribution medium), accompanied by the
   1.257 +    Corresponding Source fixed on a durable physical medium
   1.258 +    customarily used for software interchange.
   1.259 +
   1.260 +    b) Convey the object code in, or embodied in, a physical product
   1.261 +    (including a physical distribution medium), accompanied by a
   1.262 +    written offer, valid for at least three years and valid for as
   1.263 +    long as you offer spare parts or customer support for that product
   1.264 +    model, to give anyone who possesses the object code either (1) a
   1.265 +    copy of the Corresponding Source for all the software in the
   1.266 +    product that is covered by this License, on a durable physical
   1.267 +    medium customarily used for software interchange, for a price no
   1.268 +    more than your reasonable cost of physically performing this
   1.269 +    conveying of source, or (2) access to copy the
   1.270 +    Corresponding Source from a network server at no charge.
   1.271 +
   1.272 +    c) Convey individual copies of the object code with a copy of the
   1.273 +    written offer to provide the Corresponding Source.  This
   1.274 +    alternative is allowed only occasionally and noncommercially, and
   1.275 +    only if you received the object code with such an offer, in accord
   1.276 +    with subsection 6b.
   1.277 +
   1.278 +    d) Convey the object code by offering access from a designated
   1.279 +    place (gratis or for a charge), and offer equivalent access to the
   1.280 +    Corresponding Source in the same way through the same place at no
   1.281 +    further charge.  You need not require recipients to copy the
   1.282 +    Corresponding Source along with the object code.  If the place to
   1.283 +    copy the object code is a network server, the Corresponding Source
   1.284 +    may be on a different server (operated by you or a third party)
   1.285 +    that supports equivalent copying facilities, provided you maintain
   1.286 +    clear directions next to the object code saying where to find the
   1.287 +    Corresponding Source.  Regardless of what server hosts the
   1.288 +    Corresponding Source, you remain obligated to ensure that it is
   1.289 +    available for as long as needed to satisfy these requirements.
   1.290 +
   1.291 +    e) Convey the object code using peer-to-peer transmission, provided
   1.292 +    you inform other peers where the object code and Corresponding
   1.293 +    Source of the work are being offered to the general public at no
   1.294 +    charge under subsection 6d.
   1.295 +
   1.296 +  A separable portion of the object code, whose source code is excluded
   1.297 +from the Corresponding Source as a System Library, need not be
   1.298 +included in conveying the object code work.
   1.299 +
   1.300 +  A "User Product" is either (1) a "consumer product", which means any
   1.301 +tangible personal property which is normally used for personal, family,
   1.302 +or household purposes, or (2) anything designed or sold for incorporation
   1.303 +into a dwelling.  In determining whether a product is a consumer product,
   1.304 +doubtful cases shall be resolved in favor of coverage.  For a particular
   1.305 +product received by a particular user, "normally used" refers to a
   1.306 +typical or common use of that class of product, regardless of the status
   1.307 +of the particular user or of the way in which the particular user
   1.308 +actually uses, or expects or is expected to use, the product.  A product
   1.309 +is a consumer product regardless of whether the product has substantial
   1.310 +commercial, industrial or non-consumer uses, unless such uses represent
   1.311 +the only significant mode of use of the product.
   1.312 +
   1.313 +  "Installation Information" for a User Product means any methods,
   1.314 +procedures, authorization keys, or other information required to install
   1.315 +and execute modified versions of a covered work in that User Product from
   1.316 +a modified version of its Corresponding Source.  The information must
   1.317 +suffice to ensure that the continued functioning of the modified object
   1.318 +code is in no case prevented or interfered with solely because
   1.319 +modification has been made.
   1.320 +
   1.321 +  If you convey an object code work under this section in, or with, or
   1.322 +specifically for use in, a User Product, and the conveying occurs as
   1.323 +part of a transaction in which the right of possession and use of the
   1.324 +User Product is transferred to the recipient in perpetuity or for a
   1.325 +fixed term (regardless of how the transaction is characterized), the
   1.326 +Corresponding Source conveyed under this section must be accompanied
   1.327 +by the Installation Information.  But this requirement does not apply
   1.328 +if neither you nor any third party retains the ability to install
   1.329 +modified object code on the User Product (for example, the work has
   1.330 +been installed in ROM).
   1.331 +
   1.332 +  The requirement to provide Installation Information does not include a
   1.333 +requirement to continue to provide support service, warranty, or updates
   1.334 +for a work that has been modified or installed by the recipient, or for
   1.335 +the User Product in which it has been modified or installed.  Access to a
   1.336 +network may be denied when the modification itself materially and
   1.337 +adversely affects the operation of the network or violates the rules and
   1.338 +protocols for communication across the network.
   1.339 +
   1.340 +  Corresponding Source conveyed, and Installation Information provided,
   1.341 +in accord with this section must be in a format that is publicly
   1.342 +documented (and with an implementation available to the public in
   1.343 +source code form), and must require no special password or key for
   1.344 +unpacking, reading or copying.
   1.345 +
   1.346 +  7. Additional Terms.
   1.347 +
   1.348 +  "Additional permissions" are terms that supplement the terms of this
   1.349 +License by making exceptions from one or more of its conditions.
   1.350 +Additional permissions that are applicable to the entire Program shall
   1.351 +be treated as though they were included in this License, to the extent
   1.352 +that they are valid under applicable law.  If additional permissions
   1.353 +apply only to part of the Program, that part may be used separately
   1.354 +under those permissions, but the entire Program remains governed by
   1.355 +this License without regard to the additional permissions.
   1.356 +
   1.357 +  When you convey a copy of a covered work, you may at your option
   1.358 +remove any additional permissions from that copy, or from any part of
   1.359 +it.  (Additional permissions may be written to require their own
   1.360 +removal in certain cases when you modify the work.)  You may place
   1.361 +additional permissions on material, added by you to a covered work,
   1.362 +for which you have or can give appropriate copyright permission.
   1.363 +
   1.364 +  Notwithstanding any other provision of this License, for material you
   1.365 +add to a covered work, you may (if authorized by the copyright holders of
   1.366 +that material) supplement the terms of this License with terms:
   1.367 +
   1.368 +    a) Disclaiming warranty or limiting liability differently from the
   1.369 +    terms of sections 15 and 16 of this License; or
   1.370 +
   1.371 +    b) Requiring preservation of specified reasonable legal notices or
   1.372 +    author attributions in that material or in the Appropriate Legal
   1.373 +    Notices displayed by works containing it; or
   1.374 +
   1.375 +    c) Prohibiting misrepresentation of the origin of that material, or
   1.376 +    requiring that modified versions of such material be marked in
   1.377 +    reasonable ways as different from the original version; or
   1.378 +
   1.379 +    d) Limiting the use for publicity purposes of names of licensors or
   1.380 +    authors of the material; or
   1.381 +
   1.382 +    e) Declining to grant rights under trademark law for use of some
   1.383 +    trade names, trademarks, or service marks; or
   1.384 +
   1.385 +    f) Requiring indemnification of licensors and authors of that
   1.386 +    material by anyone who conveys the material (or modified versions of
   1.387 +    it) with contractual assumptions of liability to the recipient, for
   1.388 +    any liability that these contractual assumptions directly impose on
   1.389 +    those licensors and authors.
   1.390 +
   1.391 +  All other non-permissive additional terms are considered "further
   1.392 +restrictions" within the meaning of section 10.  If the Program as you
   1.393 +received it, or any part of it, contains a notice stating that it is
   1.394 +governed by this License along with a term that is a further
   1.395 +restriction, you may remove that term.  If a license document contains
   1.396 +a further restriction but permits relicensing or conveying under this
   1.397 +License, you may add to a covered work material governed by the terms
   1.398 +of that license document, provided that the further restriction does
   1.399 +not survive such relicensing or conveying.
   1.400 +
   1.401 +  If you add terms to a covered work in accord with this section, you
   1.402 +must place, in the relevant source files, a statement of the
   1.403 +additional terms that apply to those files, or a notice indicating
   1.404 +where to find the applicable terms.
   1.405 +
   1.406 +  Additional terms, permissive or non-permissive, may be stated in the
   1.407 +form of a separately written license, or stated as exceptions;
   1.408 +the above requirements apply either way.
   1.409 +
   1.410 +  8. Termination.
   1.411 +
   1.412 +  You may not propagate or modify a covered work except as expressly
   1.413 +provided under this License.  Any attempt otherwise to propagate or
   1.414 +modify it is void, and will automatically terminate your rights under
   1.415 +this License (including any patent licenses granted under the third
   1.416 +paragraph of section 11).
   1.417 +
   1.418 +  However, if you cease all violation of this License, then your
   1.419 +license from a particular copyright holder is reinstated (a)
   1.420 +provisionally, unless and until the copyright holder explicitly and
   1.421 +finally terminates your license, and (b) permanently, if the copyright
   1.422 +holder fails to notify you of the violation by some reasonable means
   1.423 +prior to 60 days after the cessation.
   1.424 +
   1.425 +  Moreover, your license from a particular copyright holder is
   1.426 +reinstated permanently if the copyright holder notifies you of the
   1.427 +violation by some reasonable means, this is the first time you have
   1.428 +received notice of violation of this License (for any work) from that
   1.429 +copyright holder, and you cure the violation prior to 30 days after
   1.430 +your receipt of the notice.
   1.431 +
   1.432 +  Termination of your rights under this section does not terminate the
   1.433 +licenses of parties who have received copies or rights from you under
   1.434 +this License.  If your rights have been terminated and not permanently
   1.435 +reinstated, you do not qualify to receive new licenses for the same
   1.436 +material under section 10.
   1.437 +
   1.438 +  9. Acceptance Not Required for Having Copies.
   1.439 +
   1.440 +  You are not required to accept this License in order to receive or
   1.441 +run a copy of the Program.  Ancillary propagation of a covered work
   1.442 +occurring solely as a consequence of using peer-to-peer transmission
   1.443 +to receive a copy likewise does not require acceptance.  However,
   1.444 +nothing other than this License grants you permission to propagate or
   1.445 +modify any covered work.  These actions infringe copyright if you do
   1.446 +not accept this License.  Therefore, by modifying or propagating a
   1.447 +covered work, you indicate your acceptance of this License to do so.
   1.448 +
   1.449 +  10. Automatic Licensing of Downstream Recipients.
   1.450 +
   1.451 +  Each time you convey a covered work, the recipient automatically
   1.452 +receives a license from the original licensors, to run, modify and
   1.453 +propagate that work, subject to this License.  You are not responsible
   1.454 +for enforcing compliance by third parties with this License.
   1.455 +
   1.456 +  An "entity transaction" is a transaction transferring control of an
   1.457 +organization, or substantially all assets of one, or subdividing an
   1.458 +organization, or merging organizations.  If propagation of a covered
   1.459 +work results from an entity transaction, each party to that
   1.460 +transaction who receives a copy of the work also receives whatever
   1.461 +licenses to the work the party's predecessor in interest had or could
   1.462 +give under the previous paragraph, plus a right to possession of the
   1.463 +Corresponding Source of the work from the predecessor in interest, if
   1.464 +the predecessor has it or can get it with reasonable efforts.
   1.465 +
   1.466 +  You may not impose any further restrictions on the exercise of the
   1.467 +rights granted or affirmed under this License.  For example, you may
   1.468 +not impose a license fee, royalty, or other charge for exercise of
   1.469 +rights granted under this License, and you may not initiate litigation
   1.470 +(including a cross-claim or counterclaim in a lawsuit) alleging that
   1.471 +any patent claim is infringed by making, using, selling, offering for
   1.472 +sale, or importing the Program or any portion of it.
   1.473 +
   1.474 +  11. Patents.
   1.475 +
   1.476 +  A "contributor" is a copyright holder who authorizes use under this
   1.477 +License of the Program or a work on which the Program is based.  The
   1.478 +work thus licensed is called the contributor's "contributor version".
   1.479 +
   1.480 +  A contributor's "essential patent claims" are all patent claims
   1.481 +owned or controlled by the contributor, whether already acquired or
   1.482 +hereafter acquired, that would be infringed by some manner, permitted
   1.483 +by this License, of making, using, or selling its contributor version,
   1.484 +but do not include claims that would be infringed only as a
   1.485 +consequence of further modification of the contributor version.  For
   1.486 +purposes of this definition, "control" includes the right to grant
   1.487 +patent sublicenses in a manner consistent with the requirements of
   1.488 +this License.
   1.489 +
   1.490 +  Each contributor grants you a non-exclusive, worldwide, royalty-free
   1.491 +patent license under the contributor's essential patent claims, to
   1.492 +make, use, sell, offer for sale, import and otherwise run, modify and
   1.493 +propagate the contents of its contributor version.
   1.494 +
   1.495 +  In the following three paragraphs, a "patent license" is any express
   1.496 +agreement or commitment, however denominated, not to enforce a patent
   1.497 +(such as an express permission to practice a patent or covenant not to
   1.498 +sue for patent infringement).  To "grant" such a patent license to a
   1.499 +party means to make such an agreement or commitment not to enforce a
   1.500 +patent against the party.
   1.501 +
   1.502 +  If you convey a covered work, knowingly relying on a patent license,
   1.503 +and the Corresponding Source of the work is not available for anyone
   1.504 +to copy, free of charge and under the terms of this License, through a
   1.505 +publicly available network server or other readily accessible means,
   1.506 +then you must either (1) cause the Corresponding Source to be so
   1.507 +available, or (2) arrange to deprive yourself of the benefit of the
   1.508 +patent license for this particular work, or (3) arrange, in a manner
   1.509 +consistent with the requirements of this License, to extend the patent
   1.510 +license to downstream recipients.  "Knowingly relying" means you have
   1.511 +actual knowledge that, but for the patent license, your conveying the
   1.512 +covered work in a country, or your recipient's use of the covered work
   1.513 +in a country, would infringe one or more identifiable patents in that
   1.514 +country that you have reason to believe are valid.
   1.515 +
   1.516 +  If, pursuant to or in connection with a single transaction or
   1.517 +arrangement, you convey, or propagate by procuring conveyance of, a
   1.518 +covered work, and grant a patent license to some of the parties
   1.519 +receiving the covered work authorizing them to use, propagate, modify
   1.520 +or convey a specific copy of the covered work, then the patent license
   1.521 +you grant is automatically extended to all recipients of the covered
   1.522 +work and works based on it.
   1.523 +
   1.524 +  A patent license is "discriminatory" if it does not include within
   1.525 +the scope of its coverage, prohibits the exercise of, or is
   1.526 +conditioned on the non-exercise of one or more of the rights that are
   1.527 +specifically granted under this License.  You may not convey a covered
   1.528 +work if you are a party to an arrangement with a third party that is
   1.529 +in the business of distributing software, under which you make payment
   1.530 +to the third party based on the extent of your activity of conveying
   1.531 +the work, and under which the third party grants, to any of the
   1.532 +parties who would receive the covered work from you, a discriminatory
   1.533 +patent license (a) in connection with copies of the covered work
   1.534 +conveyed by you (or copies made from those copies), or (b) primarily
   1.535 +for and in connection with specific products or compilations that
   1.536 +contain the covered work, unless you entered into that arrangement,
   1.537 +or that patent license was granted, prior to 28 March 2007.
   1.538 +
   1.539 +  Nothing in this License shall be construed as excluding or limiting
   1.540 +any implied license or other defenses to infringement that may
   1.541 +otherwise be available to you under applicable patent law.
   1.542 +
   1.543 +  12. No Surrender of Others' Freedom.
   1.544 +
   1.545 +  If conditions are imposed on you (whether by court order, agreement or
   1.546 +otherwise) that contradict the conditions of this License, they do not
   1.547 +excuse you from the conditions of this License.  If you cannot convey a
   1.548 +covered work so as to satisfy simultaneously your obligations under this
   1.549 +License and any other pertinent obligations, then as a consequence you may
   1.550 +not convey it at all.  For example, if you agree to terms that obligate you
   1.551 +to collect a royalty for further conveying from those to whom you convey
   1.552 +the Program, the only way you could satisfy both those terms and this
   1.553 +License would be to refrain entirely from conveying the Program.
   1.554 +
   1.555 +  13. Use with the GNU Affero General Public License.
   1.556 +
   1.557 +  Notwithstanding any other provision of this License, you have
   1.558 +permission to link or combine any covered work with a work licensed
   1.559 +under version 3 of the GNU Affero General Public License into a single
   1.560 +combined work, and to convey the resulting work.  The terms of this
   1.561 +License will continue to apply to the part which is the covered work,
   1.562 +but the special requirements of the GNU Affero General Public License,
   1.563 +section 13, concerning interaction through a network will apply to the
   1.564 +combination as such.
   1.565 +
   1.566 +  14. Revised Versions of this License.
   1.567 +
   1.568 +  The Free Software Foundation may publish revised and/or new versions of
   1.569 +the GNU General Public License from time to time.  Such new versions will
   1.570 +be similar in spirit to the present version, but may differ in detail to
   1.571 +address new problems or concerns.
   1.572 +
   1.573 +  Each version is given a distinguishing version number.  If the
   1.574 +Program specifies that a certain numbered version of the GNU General
   1.575 +Public License "or any later version" applies to it, you have the
   1.576 +option of following the terms and conditions either of that numbered
   1.577 +version or of any later version published by the Free Software
   1.578 +Foundation.  If the Program does not specify a version number of the
   1.579 +GNU General Public License, you may choose any version ever published
   1.580 +by the Free Software Foundation.
   1.581 +
   1.582 +  If the Program specifies that a proxy can decide which future
   1.583 +versions of the GNU General Public License can be used, that proxy's
   1.584 +public statement of acceptance of a version permanently authorizes you
   1.585 +to choose that version for the Program.
   1.586 +
   1.587 +  Later license versions may give you additional or different
   1.588 +permissions.  However, no additional obligations are imposed on any
   1.589 +author or copyright holder as a result of your choosing to follow a
   1.590 +later version.
   1.591 +
   1.592 +  15. Disclaimer of Warranty.
   1.593 +
   1.594 +  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
   1.595 +APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
   1.596 +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
   1.597 +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
   1.598 +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
   1.599 +PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
   1.600 +IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
   1.601 +ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
   1.602 +
   1.603 +  16. Limitation of Liability.
   1.604 +
   1.605 +  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
   1.606 +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
   1.607 +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
   1.608 +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
   1.609 +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
   1.610 +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
   1.611 +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
   1.612 +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
   1.613 +SUCH DAMAGES.
   1.614 +
   1.615 +  17. Interpretation of Sections 15 and 16.
   1.616 +
   1.617 +  If the disclaimer of warranty and limitation of liability provided
   1.618 +above cannot be given local legal effect according to their terms,
   1.619 +reviewing courts shall apply local law that most closely approximates
   1.620 +an absolute waiver of all civil liability in connection with the
   1.621 +Program, unless a warranty or assumption of liability accompanies a
   1.622 +copy of the Program in return for a fee.
   1.623 +
   1.624 +                     END OF TERMS AND CONDITIONS
   1.625 +
   1.626 +            How to Apply These Terms to Your New Programs
   1.627 +
   1.628 +  If you develop a new program, and you want it to be of the greatest
   1.629 +possible use to the public, the best way to achieve this is to make it
   1.630 +free software which everyone can redistribute and change under these terms.
   1.631 +
   1.632 +  To do so, attach the following notices to the program.  It is safest
   1.633 +to attach them to the start of each source file to most effectively
   1.634 +state the exclusion of warranty; and each file should have at least
   1.635 +the "copyright" line and a pointer to where the full notice is found.
   1.636 +
   1.637 +    <one line to give the program's name and a brief idea of what it does.>
   1.638 +    Copyright (C) <year>  <name of author>
   1.639 +
   1.640 +    This program is free software: you can redistribute it and/or modify
   1.641 +    it under the terms of the GNU General Public License as published by
   1.642 +    the Free Software Foundation, either version 3 of the License, or
   1.643 +    (at your option) any later version.
   1.644 +
   1.645 +    This program is distributed in the hope that it will be useful,
   1.646 +    but WITHOUT ANY WARRANTY; without even the implied warranty of
   1.647 +    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
   1.648 +    GNU General Public License for more details.
   1.649 +
   1.650 +    You should have received a copy of the GNU General Public License
   1.651 +    along with this program.  If not, see <http://www.gnu.org/licenses/>.
   1.652 +
   1.653 +Also add information on how to contact you by electronic and paper mail.
   1.654 +
   1.655 +  If the program does terminal interaction, make it output a short
   1.656 +notice like this when it starts in an interactive mode:
   1.657 +
   1.658 +    <program>  Copyright (C) <year>  <name of author>
   1.659 +    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
   1.660 +    This is free software, and you are welcome to redistribute it
   1.661 +    under certain conditions; type `show c' for details.
   1.662 +
   1.663 +The hypothetical commands `show w' and `show c' should show the appropriate
   1.664 +parts of the General Public License.  Of course, your program's commands
   1.665 +might be different; for a GUI interface, you would use an "about box".
   1.666 +
   1.667 +  You should also get your employer (if you work as a programmer) or school,
   1.668 +if any, to sign a "copyright disclaimer" for the program, if necessary.
   1.669 +For more information on this, and how to apply and follow the GNU GPL, see
   1.670 +<http://www.gnu.org/licenses/>.
   1.671 +
   1.672 +  The GNU General Public License does not permit incorporating your program
   1.673 +into proprietary programs.  If your program is a subroutine library, you
   1.674 +may consider it more useful to permit linking proprietary applications with
   1.675 +the library.  If this is what you want to do, use the GNU Lesser General
   1.676 +Public License instead of this License.  But first, please read
   1.677 +<http://www.gnu.org/philosophy/why-not-lgpl.html>.

    7.11 +                            Preamble
    7.12 +
    7.13 +  The GNU General Public License is a free, copyleft license for
    7.14 +software and other kinds of works.
    7.15 +
    7.16 +  The licenses for most software and other practical works are designed
    7.17 +to take away your freedom to share and change the works.  By contrast,
    7.18 +the GNU General Public License is intended to guarantee your freedom to
    7.19 +share and change all versions of a program--to make sure it remains free
    7.20 +software for all its users.  We, the Free Software Foundation, use the
    7.21 +GNU General Public License for most of our software; it applies also to
    7.22 +any other work released this way by its authors.  You can apply it to
    7.23 +your programs, too.
    7.24 +
    7.25 +  When we speak of free software, we are referring to freedom, not
    7.26 +price.  Our General Public Licenses are designed to make sure that you
    7.27 +have the freedom to distribute copies of free software (and charge for
    7.28 +them if you wish), that you receive source code or can get it if you
    7.29 +want it, that you can change the software or use pieces of it in new
    7.30 +free programs, and that you know you can do these things.
    7.31 +
    7.32 +  To protect your rights, we need to prevent others from denying you
    7.33 +these rights or asking you to surrender the rights.  Therefore, you have
    7.34 +certain responsibilities if you distribute copies of the software, or if
    7.35 +you modify it: responsibilities to respect the freedom of others.
    7.36 +
    7.37 +  For example, if you distribute copies of such a program, whether
    7.38 +gratis or for a fee, you must pass on to the recipients the same
    7.39 +freedoms that you received.  You must make sure that they, too, receive
    7.40 +or can get the source code.  And you must show them these terms so they
    7.41 +know their rights.
    7.42 +
    7.43 +  Developers that use the GNU GPL protect your rights with two steps:
    7.44 +(1) assert copyright on the software, and (2) offer you this License
    7.45 +giving you legal permission to copy, distribute and/or modify it.
    7.46 +
    7.47 +  For the developers' and authors' protection, the GPL clearly explains
    7.48 +that there is no warranty for this free software.  For both users' and
    7.49 +authors' sake, the GPL requires that modified versions be marked as
    7.50 +changed, so that their problems will not be attributed erroneously to
    7.51 +authors of previous versions.
    7.52 +
    7.53 +  Some devices are designed to deny users access to install or run
    7.54 +modified versions of the software inside them, although the manufacturer
    7.55 +can do so.  This is fundamentally incompatible with the aim of
    7.56 +protecting users' freedom to change the software.  The systematic
    7.57 +pattern of such abuse occurs in the area of products for individuals to
    7.58 +use, which is precisely where it is most unacceptable.  Therefore, we
    7.59 +have designed this version of the GPL to prohibit the practice for those
    7.60 +products.  If such problems arise substantially in other domains, we
    7.61 +stand ready to extend this provision to those domains in future versions
    7.62 +of the GPL, as needed to protect the freedom of users.
    7.63 +
    7.64 +  Finally, every program is threatened constantly by software patents.
    7.65 +States should not allow patents to restrict development and use of
    7.66 +software on general-purpose computers, but in those that do, we wish to
    7.67 +avoid the special danger that patents applied to a free program could
    7.68 +make it effectively proprietary.  To prevent this, the GPL assures that
    7.69 +patents cannot be used to render the program non-free.
    7.70 +
    7.71 +  The precise terms and conditions for copying, distribution and
    7.72 +modification follow.
    7.73 +
    7.74 +                       TERMS AND CONDITIONS
    7.75 +
    7.76 +  0. Definitions.
    7.77 +
    7.78 +  "This License" refers to version 3 of the GNU General Public License.
    7.79 +
    7.80 +  "Copyright" also means copyright-like laws that apply to other kinds of
    7.81 +works, such as semiconductor masks.
    7.82 +
    7.83 +  "The Program" refers to any copyrightable work licensed under this
    7.84 +License.  Each licensee is addressed as "you".  "Licensees" and
    7.85 +"recipients" may be individuals or organizations.
    7.86 +
    7.87 +  To "modify" a work means to copy from or adapt all or part of the work
    7.88 +in a fashion requiring copyright permission, other than the making of an
    7.89 +exact copy.  The resulting work is called a "modified version" of the
    7.90 +earlier work or a work "based on" the earlier work.
    7.91 +
    7.92 +  A "covered work" means either the unmodified Program or a work based
    7.93 +on the Program.
    7.94 +
    7.95 +  To "propagate" a work means to do anything with it that, without
    7.96 +permission, would make you directly or secondarily liable for
    7.97 +infringement under applicable copyright law, except executing it on a
    7.98 +computer or modifying a private copy.  Propagation includes copying,
    7.99 +distribution (with or without modification), making available to the
   7.100 +public, and in some countries other activities as well.
   7.101 +
   7.102 +  To "convey" a work means any kind of propagation that enables other
   7.103 +parties to make or receive copies.  Mere interaction with a user through
   7.104 +a computer network, with no transfer of a copy, is not conveying.
   7.105 +
   7.106 +  An interactive user interface displays "Appropriate Legal Notices"
   7.107 +to the extent that it includes a convenient and prominently visible
   7.108 +feature that (1) displays an appropriate copyright notice, and (2)
   7.109 +tells the user that there is no warranty for the work (except to the
   7.110 +extent that warranties are provided), that licensees may convey the
   7.111 +work under this License, and how to view a copy of this License.  If
   7.112 +the interface presents a list of user commands or options, such as a
   7.113 +menu, a prominent item in the list meets this criterion.
   7.114 +
   7.115 +  1. Source Code.
   7.116 +
   7.117 +  The "source code" for a work means the preferred form of the work
   7.118 +for making modifications to it.  "Object code" means any non-source
   7.119 +form of a work.
   7.120 +
   7.121 +  A "Standard Interface" means an interface that either is an official
   7.122 +standard defined by a recognized standards body, or, in the case of
   7.123 +interfaces specified for a particular programming language, one that
   7.124 +is widely used among developers working in that language.
   7.125 +
   7.126 +  The "System Libraries" of an executable work include anything, other
   7.127 +than the work as a whole, that (a) is included in the normal form of
   7.128 +packaging a Major Component, but which is not part of that Major
   7.129 +Component, and (b) serves only to enable use of the work with that
   7.130 +Major Component, or to implement a Standard Interface for which an
   7.131 +implementation is available to the public in source code form.  A
   7.132 +"Major Component", in this context, means a major essential component
   7.133 +(kernel, window system, and so on) of the specific operating system
   7.134 +(if any) on which the executable work runs, or a compiler used to
   7.135 +produce the work, or an object code interpreter used to run it.
   7.136 +
   7.137 +  The "Corresponding Source" for a work in object code form means all
   7.138 +the source code needed to generate, install, and (for an executable
   7.139 +work) run the object code and to modify the work, including scripts to
   7.140 +control those activities.  However, it does not include the work's
   7.141 +System Libraries, or general-purpose tools or generally available free
   7.142 +programs which are used unmodified in performing those activities but
   7.143 +which are not part of the work.  For example, Corresponding Source
   7.144 +includes interface definition files associated with source files for
   7.145 +the work, and the source code for shared libraries and dynamically
   7.146 +linked subprograms that the work is specifically designed to require,
   7.147 +such as by intimate data communication or control flow between those
   7.148 +subprograms and other parts of the work.
   7.149 +
   7.150 +  The Corresponding Source need not include anything that users
   7.151 +can regenerate automatically from other parts of the Corresponding
   7.152 +Source.
   7.153 +
   7.154 +  The Corresponding Source for a work in source code form is that
   7.155 +same work.
   7.156 +
   7.157 +  2. Basic Permissions.
   7.158 +
   7.159 +  All rights granted under this License are granted for the term of
   7.160 +copyright on the Program, and are irrevocable provided the stated
   7.161 +conditions are met.  This License explicitly affirms your unlimited
   7.162 +permission to run the unmodified Program.  The output from running a
   7.163 +covered work is covered by this License only if the output, given its
   7.164 +content, constitutes a covered work.  This License acknowledges your
   7.165 +rights of fair use or other equivalent, as provided by copyright law.
   7.166 +
   7.167 +  You may make, run and propagate covered works that you do not
   7.168 +convey, without conditions so long as your license otherwise remains
   7.169 +in force.  You may convey covered works to others for the sole purpose
   7.170 +of having them make modifications exclusively for you, or provide you
   7.171 +with facilities for running those works, provided that you comply with
   7.172 +the terms of this License in conveying all material for which you do
   7.173 +not control copyright.  Those thus making or running the covered works
   7.174 +for you must do so exclusively on your behalf, under your direction
   7.175 +and control, on terms that prohibit them from making any copies of
   7.176 +your copyrighted material outside their relationship with you.
   7.177 +
   7.178 +  Conveying under any other circumstances is permitted solely under
   7.179 +the conditions stated below.  Sublicensing is not allowed; section 10
   7.180 +makes it unnecessary.
   7.181 +
   7.182 +  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
   7.183 +
   7.184 +  No covered work shall be deemed part of an effective technological
   7.185 +measure under any applicable law fulfilling obligations under article
   7.186 +11 of the WIPO copyright treaty adopted on 20 December 1996, or
   7.187 +similar laws prohibiting or restricting circumvention of such
   7.188 +measures.
   7.189 +
   7.190 +  When you convey a covered work, you waive any legal power to forbid
   7.191 +circumvention of technological measures to the extent such circumvention
   7.192 +is effected by exercising rights under this License with respect to
   7.193 +the covered work, and you disclaim any intention to limit operation or
   7.194 +modification of the work as a means of enforcing, against the work's
   7.195 +users, your or third parties' legal rights to forbid circumvention of
   7.196 +technological measures.
   7.197 +
   7.198 +  4. Conveying Verbatim Copies.
   7.199 +
   7.200 +  You may convey verbatim copies of the Program's source code as you
   7.201 +receive it, in any medium, provided that you conspicuously and
   7.202 +appropriately publish on each copy an appropriate copyright notice;
   7.203 +keep intact all notices stating that this License and any
   7.204 +non-permissive terms added in accord with section 7 apply to the code;
   7.205 +keep intact all notices of the absence of any warranty; and give all
   7.206 +recipients a copy of this License along with the Program.
   7.207 +
   7.208 +  You may charge any price or no price for each copy that you convey,
   7.209 +and you may offer support or warranty protection for a fee.
   7.210 +
   7.211 +  5. Conveying Modified Source Versions.
   7.212 +
   7.213 +  You may convey a work based on the Program, or the modifications to
   7.214 +produce it from the Program, in the form of source code under the
   7.215 +terms of section 4, provided that you also meet all of these conditions:
   7.216 +
   7.217 +    a) The work must carry prominent notices stating that you modified
   7.218 +    it, and giving a relevant date.
   7.219 +
   7.220 +    b) The work must carry prominent notices stating that it is
   7.221 +    released under this License and any conditions added under section
   7.222 +    7.  This requirement modifies the requirement in section 4 to
   7.223 +    "keep intact all notices".
   7.224 +
   7.225 +    c) You must license the entire work, as a whole, under this
   7.226 +    License to anyone who comes into possession of a copy.  This
   7.227 +    License will therefore apply, along with any applicable section 7
   7.228 +    additional terms, to the whole of the work, and all its parts,
   7.229 +    regardless of how they are packaged.  This License gives no
   7.230 +    permission to license the work in any other way, but it does not
   7.231 +    invalidate such permission if you have separately received it.
   7.232 +
   7.233 +    d) If the work has interactive user interfaces, each must display
   7.234 +    Appropriate Legal Notices; however, if the Program has interactive
   7.235 +    interfaces that do not display Appropriate Legal Notices, your
   7.236 +    work need not make them do so.
   7.237 +
   7.238 +  A compilation of a covered work with other separate and independent
   7.239 +works, which are not by their nature extensions of the covered work,
   7.240 +and which are not combined with it such as to form a larger program,
   7.241 +in or on a volume of a storage or distribution medium, is called an
   7.242 +"aggregate" if the compilation and its resulting copyright are not
   7.243 +used to limit the access or legal rights of the compilation's users
   7.244 +beyond what the individual works permit.  Inclusion of a covered work
   7.245 +in an aggregate does not cause this License to apply to the other
   7.246 +parts of the aggregate.
   7.247 +
   7.248 +  6. Conveying Non-Source Forms.
   7.249 +
   7.250 +  You may convey a covered work in object code form under the terms
   7.251 +of sections 4 and 5, provided that you also convey the
   7.252 +machine-readable Corresponding Source under the terms of this License,
   7.253 +in one of these ways:
   7.254 +
   7.255 +    a) Convey the object code in, or embodied in, a physical product
   7.256 +    (including a physical distribution medium), accompanied by the
   7.257 +    Corresponding Source fixed on a durable physical medium
   7.258 +    customarily used for software interchange.
   7.259 +
   7.260 +    b) Convey the object code in, or embodied in, a physical product
   7.261 +    (including a physical distribution medium), accompanied by a
   7.262 +    written offer, valid for at least three years and valid for as
   7.263 +    long as you offer spare parts or customer support for that product
   7.264 +    model, to give anyone who possesses the object code either (1) a
   7.265 +    copy of the Corresponding Source for all the software in the
   7.266 +    product that is covered by this License, on a durable physical
   7.267 +    medium customarily used for software interchange, for a price no
   7.268 +    more than your reasonable cost of physically performing this
   7.269 +    conveying of source, or (2) access to copy the
   7.270 +    Corresponding Source from a network server at no charge.
   7.271 +
   7.272 +    c) Convey individual copies of the object code with a copy of the
   7.273 +    written offer to provide the Corresponding Source.  This
   7.274 +    alternative is allowed only occasionally and noncommercially, and
   7.275 +    only if you received the object code with such an offer, in accord
   7.276 +    with subsection 6b.
   7.277 +
   7.278 +    d) Convey the object code by offering access from a designated
   7.279 +    place (gratis or for a charge), and offer equivalent access to the
   7.280 +    Corresponding Source in the same way through the same place at no
   7.281 +    further charge.  You need not require recipients to copy the
   7.282 +    Corresponding Source along with the object code.  If the place to
   7.283 +    copy the object code is a network server, the Corresponding Source
   7.284 +    may be on a different server (operated by you or a third party)
   7.285 +    that supports equivalent copying facilities, provided you maintain
   7.286 +    clear directions next to the object code saying where to find the
   7.287 +    Corresponding Source.  Regardless of what server hosts the
   7.288 +    Corresponding Source, you remain obligated to ensure that it is
   7.289 +    available for as long as needed to satisfy these requirements.
   7.290 +
   7.291 +    e) Convey the object code using peer-to-peer transmission, provided
   7.292 +    you inform other peers where the object code and Corresponding
   7.293 +    Source of the work are being offered to the general public at no
   7.294 +    charge under subsection 6d.
   7.295 +
   7.296 +  A separable portion of the object code, whose source code is excluded
   7.297 +from the Corresponding Source as a System Library, need not be
   7.298 +included in conveying the object code work.
   7.299 +
   7.300 +  A "User Product" is either (1) a "consumer product", which means any
   7.301 +tangible personal property which is normally used for personal, family,
   7.302 +or household purposes, or (2) anything designed or sold for incorporation
   7.303 +into a dwelling.  In determining whether a product is a consumer product,
   7.304 +doubtful cases shall be resolved in favor of coverage.  For a particular
   7.305 +product received by a particular user, "normally used" refers to a
   7.306 +typical or common use of that class of product, regardless of the status
   7.307 +of the particular user or of the way in which the particular user
   7.308 +actually uses, or expects or is expected to use, the product.  A product
   7.309 +is a consumer product regardless of whether the product has substantial
   7.310 +commercial, industrial or non-consumer uses, unless such uses represent
   7.311 +the only significant mode of use of the product.
   7.312 +
   7.313 +  "Installation Information" for a User Product means any methods,
   7.314 +procedures, authorization keys, or other information required to install
   7.315 +and execute modified versions of a covered work in that User Product from
   7.316 +a modified version of its Corresponding Source.  The information must
   7.317 +suffice to ensure that the continued functioning of the modified object
   7.318 +code is in no case prevented or interfered with solely because
   7.319 +modification has been made.
   7.320 +
   7.321 +  If you convey an object code work under this section in, or with, or
   7.322 +specifically for use in, a User Product, and the conveying occurs as
   7.323 +part of a transaction in which the right of possession and use of the
   7.324 +User Product is transferred to the recipient in perpetuity or for a
   7.325 +fixed term (regardless of how the transaction is characterized), the
   7.326 +Corresponding Source conveyed under this section must be accompanied
   7.327 +by the Installation Information.  But this requirement does not apply
   7.328 +if neither you nor any third party retains the ability to install
   7.329 +modified object code on the User Product (for example, the work has
   7.330 +been installed in ROM).
   7.331 +
   7.332 +  The requirement to provide Installation Information does not include a
   7.333 +requirement to continue to provide support service, warranty, or updates
   7.334 +for a work that has been modified or installed by the recipient, or for
   7.335 +the User Product in which it has been modified or installed.  Access to a
   7.336 +network may be denied when the modification itself materially and
   7.337 +adversely affects the operation of the network or violates the rules and
   7.338 +protocols for communication across the network.
   7.339 +
   7.340 +  Corresponding Source conveyed, and Installation Information provided,
   7.341 +in accord with this section must be in a format that is publicly
   7.342 +documented (and with an implementation available to the public in
   7.343 +source code form), and must require no special password or key for
   7.344 +unpacking, reading or copying.
   7.345 +
   7.346 +  7. Additional Terms.
   7.347 +
   7.348 +  "Additional permissions" are terms that supplement the terms of this
   7.349 +License by making exceptions from one or more of its conditions.
   7.350 +Additional permissions that are applicable to the entire Program shall
   7.351 +be treated as though they were included in this License, to the extent
   7.352 +that they are valid under applicable law.  If additional permissions
   7.353 +apply only to part of the Program, that part may be used separately
   7.354 +under those permissions, but the entire Program remains governed by
   7.355 +this License without regard to the additional permissions.
   7.356 +
   7.357 +  When you convey a copy of a covered work, you may at your option
   7.358 +remove any additional permissions from that copy, or from any part of
   7.359 +it.  (Additional permissions may be written to require their own
   7.360 +removal in certain cases when you modify the work.)  You may place
   7.361 +additional permissions on material, added by you to a covered work,
   7.362 +for which you have or can give appropriate copyright permission.
   7.363 +
   7.364 +  Notwithstanding any other provision of this License, for material you
   7.365 +add to a covered work, you may (if authorized by the copyright holders of
   7.366 +that material) supplement the terms of this License with terms:
   7.367 +
   7.368 +    a) Disclaiming warranty or limiting liability differently from the
   7.369 +    terms of sections 15 and 16 of this License; or
   7.370 +
   7.371 +    b) Requiring preservation of specified reasonable legal notices or
   7.372 +    author attributions in that material or in the Appropriate Legal
   7.373 +    Notices displayed by works containing it; or
   7.374 +
   7.375 +    c) Prohibiting misrepresentation of the origin of that material, or
   7.376 +    requiring that modified versions of such material be marked in
   7.377 +    reasonable ways as different from the original version; or
   7.378 +
   7.379 +    d) Limiting the use for publicity purposes of names of licensors or
   7.380 +    authors of the material; or
   7.381 +
   7.382 +    e) Declining to grant rights under trademark law for use of some
   7.383 +    trade names, trademarks, or service marks; or
   7.384 +
   7.385 +    f) Requiring indemnification of licensors and authors of that
   7.386 +    material by anyone who conveys the material (or modified versions of
   7.387 +    it) with contractual assumptions of liability to the recipient, for
   7.388 +    any liability that these contractual assumptions directly impose on
   7.389 +    those licensors and authors.
   7.390 +
   7.391 +  All other non-permissive additional terms are considered "further
   7.392 +restrictions" within the meaning of section 10.  If the Program as you
   7.393 +received it, or any part of it, contains a notice stating that it is
   7.394 +governed by this License along with a term that is a further
   7.395 +restriction, you may remove that term.  If a license document contains
   7.396 +a further restriction but permits relicensing or conveying under this
   7.397 +License, you may add to a covered work material governed by the terms
   7.398 +of that license document, provided that the further restriction does
   7.399 +not survive such relicensing or conveying.
   7.400 +
   7.401 +  If you add terms to a covered work in accord with this section, you
   7.402 +must place, in the relevant source files, a statement of the
   7.403 +additional terms that apply to those files, or a notice indicating
   7.404 +where to find the applicable terms.
   7.405 +
   7.406 +  Additional terms, permissive or non-permissive, may be stated in the
   7.407 +form of a separately written license, or stated as exceptions;
   7.408 +the above requirements apply either way.
   7.409 +
   7.410 +  8. Termination.
   7.411 +
   7.412 +  You may not propagate or modify a covered work except as expressly
   7.413 +provided under this License.  Any attempt otherwise to propagate or
   7.414 +modify it is void, and will automatically terminate your rights under
   7.415 +this License (including any patent licenses granted under the third
   7.416 +paragraph of section 11).
   7.417 +
   7.418 +  However, if you cease all violation of this License, then your
   7.419 +license from a particular copyright holder is reinstated (a)
   7.420 +provisionally, unless and until the copyright holder explicitly and
   7.421 +finally terminates your license, and (b) permanently, if the copyright
   7.422 +holder fails to notify you of the violation by some reasonable means
   7.423 +prior to 60 days after the cessation.
   7.424 +
   7.425 +  Moreover, your license from a particular copyright holder is
   7.426 +reinstated permanently if the copyright holder notifies you of the
   7.427 +violation by some reasonable means, this is the first time you have
   7.428 +received notice of violation of this License (for any work) from that
   7.429 +copyright holder, and you cure the violation prior to 30 days after
   7.430 +your receipt of the notice.
   7.431 +
   7.432 +  Termination of your rights under this section does not terminate the
   7.433 +licenses of parties who have received copies or rights from you under
   7.434 +this License.  If your rights have been terminated and not permanently
   7.435 +reinstated, you do not qualify to receive new licenses for the same
   7.436 +material under section 10.
   7.437 +
   7.438 +  9. Acceptance Not Required for Having Copies.
   7.439 +
   7.440 +  You are not required to accept this License in order to receive or
   7.441 +run a copy of the Program.  Ancillary propagation of a covered work
   7.442 +occurring solely as a consequence of using peer-to-peer transmission
   7.443 +to receive a copy likewise does not require acceptance.  However,
   7.444 +nothing other than this License grants you permission to propagate or
   7.445 +modify any covered work.  These actions infringe copyright if you do
   7.446 +not accept this License.  Therefore, by modifying or propagating a
   7.447 +covered work, you indicate your acceptance of this License to do so.
   7.448 +
   7.449 +  10. Automatic Licensing of Downstream Recipients.
   7.450 +
   7.451 +  Each time you convey a covered work, the recipient automatically
   7.452 +receives a license from the original licensors, to run, modify and
   7.453 +propagate that work, subject to this License.  You are not responsible
   7.454 +for enforcing compliance by third parties with this License.
   7.455 +
   7.456 +  An "entity transaction" is a transaction transferring control of an
   7.457 +organization, or substantially all assets of one, or subdividing an
   7.458 +organization, or merging organizations.  If propagation of a covered
   7.459 +work results from an entity transaction, each party to that
   7.460 +transaction who receives a copy of the work also receives whatever
   7.461 +licenses to the work the party's predecessor in interest had or could
   7.462 +give under the previous paragraph, plus a right to possession of the
   7.463 +Corresponding Source of the work from the predecessor in interest, if
   7.464 +the predecessor has it or can get it with reasonable efforts.
   7.465 +
   7.466 +  You may not impose any further restrictions on the exercise of the
   7.467 +rights granted or affirmed under this License.  For example, you may
   7.468 +not impose a license fee, royalty, or other charge for exercise of
   7.469 +rights granted under this License, and you may not initiate litigation
   7.470 +(including a cross-claim or counterclaim in a lawsuit) alleging that
   7.471 +any patent claim is infringed by making, using, selling, offering for
   7.472 +sale, or importing the Program or any portion of it.
   7.473 +
   7.474 +  11. Patents.
   7.475 +
   7.476 +  A "contributor" is a copyright holder who authorizes use under this
   7.477 +License of the Program or a work on which the Program is based.  The
   7.478 +work thus licensed is called the contributor's "contributor version".
   7.479 +
   7.480 +  A contributor's "essential patent claims" are all patent claims
   7.481 +owned or controlled by the contributor, whether already acquired or
   7.482 +hereafter acquired, that would be infringed by some manner, permitted
   7.483 +by this License, of making, using, or selling its contributor version,
   7.484 +but do not include claims that would be infringed only as a
   7.485 +consequence of further modification of the contributor version.  For
   7.486 +purposes of this definition, "control" includes the right to grant
   7.487 +patent sublicenses in a manner consistent with the requirements of
   7.488 +this License.
   7.489 +
   7.490 +  Each contributor grants you a non-exclusive, worldwide, royalty-free
   7.491 +patent license under the contributor's essential patent claims, to
   7.492 +make, use, sell, offer for sale, import and otherwise run, modify and
   7.493 +propagate the contents of its contributor version.
   7.494 +
   7.495 +  In the following three paragraphs, a "patent license" is any express
   7.496 +agreement or commitment, however denominated, not to enforce a patent
   7.497 +(such as an express permission to practice a patent or covenant not to
   7.498 +sue for patent infringement).  To "grant" such a patent license to a
   7.499 +party means to make such an agreement or commitment not to enforce a
   7.500 +patent against the party.
   7.501 +
   7.502 +  If you convey a covered work, knowingly relying on a patent license,
   7.503 +and the Corresponding Source of the work is not available for anyone
   7.504 +to copy, free of charge and under the terms of this License, through a
   7.505 +publicly available network server or other readily accessible means,
   7.506 +then you must either (1) cause the Corresponding Source to be so
   7.507 +available, or (2) arrange to deprive yourself of the benefit of the
   7.508 +patent license for this particular work, or (3) arrange, in a manner
   7.509 +consistent with the requirements of this License, to extend the patent
   7.510 +license to downstream recipients.  "Knowingly relying" means you have
   7.511 +actual knowledge that, but for the patent license, your conveying the
   7.512 +covered work in a country, or your recipient's use of the covered work
   7.513 +in a country, would infringe one or more identifiable patents in that
   7.514 +country that you have reason to believe are valid.
   7.515 +
   7.516 +  If, pursuant to or in connection with a single transaction or
   7.517 +arrangement, you convey, or propagate by procuring conveyance of, a
   7.518 +covered work, and grant a patent license to some of the parties
   7.519 +receiving the covered work authorizing them to use, propagate, modify
   7.520 +or convey a specific copy of the covered work, then the patent license
   7.521 +you grant is automatically extended to all recipients of the covered
   7.522 +work and works based on it.
   7.523 +
   7.524 +  A patent license is "discriminatory" if it does not include within
   7.525 +the scope of its coverage, prohibits the exercise of, or is
   7.526 +conditioned on the non-exercise of one or more of the rights that are
   7.527 +specifically granted under this License.  You may not convey a covered
   7.528 +work if you are a party to an arrangement with a third party that is
   7.529 +in the business of distributing software, under which you make payment
   7.530 +to the third party based on the extent of your activity of conveying
   7.531 +the work, and under which the third party grants, to any of the
   7.532 +parties who would receive the covered work from you, a discriminatory
   7.533 +patent license (a) in connection with copies of the covered work
   7.534 +conveyed by you (or copies made from those copies), or (b) primarily
   7.535 +for and in connection with specific products or compilations that
   7.536 +contain the covered work, unless you entered into that arrangement,
   7.537 +or that patent license was granted, prior to 28 March 2007.
   7.538 +
   7.539 +  Nothing in this License shall be construed as excluding or limiting
   7.540 +any implied license or other defenses to infringement that may
   7.541 +otherwise be available to you under applicable patent law.
   7.542 +
   7.543 +  12. No Surrender of Others' Freedom.
   7.544 +
   7.545 +  If conditions are imposed on you (whether by court order, agreement or
   7.546 +otherwise) that contradict the conditions of this License, they do not
   7.547 +excuse you from the conditions of this License.  If you cannot convey a
   7.548 +covered work so as to satisfy simultaneously your obligations under this
   7.549 +License and any other pertinent obligations, then as a consequence you may
   7.550 +not convey it at all.  For example, if you agree to terms that obligate you
   7.551 +to collect a royalty for further conveying from those to whom you convey
   7.552 +the Program, the only way you could satisfy both those terms and this
   7.553 +License would be to refrain entirely from conveying the Program.
   7.554 +
   7.555 +  13. Use with the GNU Affero General Public License.
   7.556 +
   7.557 +  Notwithstanding any other provision of this License, you have
   7.558 +permission to link or combine any covered work with a work licensed
   7.559 +under version 3 of the GNU Affero General Public License into a single
   7.560 +combined work, and to convey the resulting work.  The terms of this
   7.561 +License will continue to apply to the part which is the covered work,
   7.562 +but the special requirements of the GNU Affero General Public License,
   7.563 +section 13, concerning interaction through a network will apply to the
   7.564 +combination as such.
   7.565 +
   7.566 +  14. Revised Versions of this License.
   7.567 +
   7.568 +  The Free Software Foundation may publish revised and/or new versions of
   7.569 +the GNU General Public License from time to time.  Such new versions will
   7.570 +be similar in spirit to the present version, but may differ in detail to
   7.571 +address new problems or concerns.
   7.572 +
   7.573 +  Each version is given a distinguishing version number.  If the
   7.574 +Program specifies that a certain numbered version of the GNU General
   7.575 +Public License "or any later version" applies to it, you have the
   7.576 +option of following the terms and conditions either of that numbered
   7.577 +version or of any later version published by the Free Software
   7.578 +Foundation.  If the Program does not specify a version number of the
   7.579 +GNU General Public License, you may choose any version ever published
   7.580 +by the Free Software Foundation.
   7.581 +
   7.582 +  If the Program specifies that a proxy can decide which future
   7.583 +versions of the GNU General Public License can be used, that proxy's
   7.584 +public statement of acceptance of a version permanently authorizes you
   7.585 +to choose that version for the Program.
   7.586 +
   7.587 +  Later license versions may give you additional or different
   7.588 +permissions.  However, no additional obligations are imposed on any
   7.589 +author or copyright holder as a result of your choosing to follow a
   7.590 +later version.
   7.591 +
   7.592 +  15. Disclaimer of Warranty.
   7.593 +
   7.594 +  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
   7.595 +APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
   7.596 +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
   7.597 +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
   7.598 +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
   7.599 +PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
   7.600 +IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
   7.601 +ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
   7.602 +
   7.603 +  16. Limitation of Liability.
   7.604 +
   7.605 +  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
   7.606 +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
   7.607 +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
   7.608 +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
   7.609 +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
   7.610 +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
   7.611 +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
   7.612 +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
   7.613 +SUCH DAMAGES.
   7.614 +
   7.615 +  17. Interpretation of Sections 15 and 16.
   7.616 +
   7.617 +  If the disclaimer of warranty and limitation of liability provided
   7.618 +above cannot be given local legal effect according to their terms,
   7.619 +reviewing courts shall apply local law that most closely approximates
   7.620 +an absolute waiver of all civil liability in connection with the
   7.621 +Program, unless a warranty or assumption of liability accompanies a
   7.622 +copy of the Program in return for a fee.
   7.623 +
   7.624 +                     END OF TERMS AND CONDITIONS
   7.625 +
   7.626 +            How to Apply These Terms to Your New Programs
   7.627 +
   7.628 +  If you develop a new program, and you want it to be of the greatest
   7.629 +possible use to the public, the best way to achieve this is to make it
   7.630 +free software which everyone can redistribute and change under these terms.
   7.631 +
   7.632 +  To do so, attach the following notices to the program.  It is safest
   7.633 +to attach them to the start of each source file to most effectively
   7.634 +state the exclusion of warranty; and each file should have at least
   7.635 +the "copyright" line and a pointer to where the full notice is found.
   7.636 +
   7.637 +    <one line to give the program's name and a brief idea of what it does.>
   7.638 +    Copyright (C) <year>  <name of author>
   7.639 +
   7.640 +    This program is free software: you can redistribute it and/or modify
   7.641 +    it under the terms of the GNU General Public License as published by
   7.642 +    the Free Software Foundation, either version 3 of the License, or
   7.643 +    (at your option) any later version.
   7.644 +
   7.645 +    This program is distributed in the hope that it will be useful,
   7.646 +    but WITHOUT ANY WARRANTY; without even the implied warranty of
   7.647 +    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
   7.648 +    GNU General Public License for more details.
   7.649 +
   7.650 +    You should have received a copy of the GNU General Public License
   7.651 +    along with this program.  If not, see <http://www.gnu.org/licenses/>.
   7.652 +
   7.653 +Also add information on how to contact you by electronic and paper mail.
   7.654 +
   7.655 +  If the program does terminal interaction, make it output a short
   7.656 +notice like this when it starts in an interactive mode:
   7.657 +
   7.658 +    <program>  Copyright (C) <year>  <name of author>
   7.659 +    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
   7.660 +    This is free software, and you are welcome to redistribute it
   7.661 +    under certain conditions; type `show c' for details.
   7.662 +
   7.663 +The hypothetical commands `show w' and `show c' should show the appropriate
   7.664 +parts of the General Public License.  Of course, your program's commands
   7.665 +might be different; for a GUI interface, you would use an "about box".
   7.666 +
   7.667 +  You should also get your employer (if you work as a programmer) or school,
   7.668 +if any, to sign a "copyright disclaimer" for the program, if necessary.
   7.669 +For more information on this, and how to apply and follow the GNU GPL, see
   7.670 +<http://www.gnu.org/licenses/>.
   7.671 +
   7.672 +  The GNU General Public License does not permit incorporating your program
   7.673 +into proprietary programs.  If your program is a subroutine library, you
   7.674 +may consider it more useful to permit linking proprietary applications with
   7.675 +the library.  If this is what you want to do, use the GNU Lesser General
   7.676 +Public License instead of this License.  But first, please read
   7.677 +<http://www.gnu.org/philosophy/why-not-lgpl.html>.

    12.5 +                       Version 3, 29 June 2007
    12.6 +
    12.7 + Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
    12.8 + Everyone is permitted to copy and distribute verbatim copies
    12.9 + of this license document, but changing it is not allowed.
   12.10 +
   12.11 +                            Preamble
   12.12 +
   12.13 +  The GNU General Public License is a free, copyleft license for
   12.14 +software and other kinds of works.
   12.15 +
   12.16 +  The licenses for most software and other practical works are designed
   12.17 +to take away your freedom to share and change the works.  By contrast,
   12.18 +the GNU General Public License is intended to guarantee your freedom to
   12.19 +share and change all versions of a program--to make sure it remains free
   12.20 +software for all its users.  We, the Free Software Foundation, use the
   12.21 +GNU General Public License for most of our software; it applies also to
   12.22 +any other work released this way by its authors.  You can apply it to
   12.23 +your programs, too.
   12.24 +
   12.25 +  When we speak of free software, we are referring to freedom, not
   12.26 +price.  Our General Public Licenses are designed to make sure that you
   12.27 +have the freedom to distribute copies of free software (and charge for
   12.28 +them if you wish), that you receive source code or can get it if you
   12.29 +want it, that you can change the software or use pieces of it in new
   12.30 +free programs, and that you know you can do these things.
   12.31 +
   12.32 +  To protect your rights, we need to prevent others from denying you
   12.33 +these rights or asking you to surrender the rights.  Therefore, you have
   12.34 +certain responsibilities if you distribute copies of the software, or if
   12.35 +you modify it: responsibilities to respect the freedom of others.
   12.36 +
   12.37 +  For example, if you distribute copies of such a program, whether
   12.38 +gratis or for a fee, you must pass on to the recipients the same
   12.39 +freedoms that you received.  You must make sure that they, too, receive
   12.40 +or can get the source code.  And you must show them these terms so they
   12.41 +know their rights.
   12.42 +
   12.43 +  Developers that use the GNU GPL protect your rights with two steps:
   12.44 +(1) assert copyright on the software, and (2) offer you this License
   12.45 +giving you legal permission to copy, distribute and/or modify it.
   12.46 +
   12.47 +  For the developers' and authors' protection, the GPL clearly explains
   12.48 +that there is no warranty for this free software.  For both users' and
   12.49 +authors' sake, the GPL requires that modified versions be marked as
   12.50 +changed, so that their problems will not be attributed erroneously to
   12.51 +authors of previous versions.
   12.52 +
   12.53 +  Some devices are designed to deny users access to install or run
   12.54 +modified versions of the software inside them, although the manufacturer
   12.55 +can do so.  This is fundamentally incompatible with the aim of
   12.56 +protecting users' freedom to change the software.  The systematic
   12.57 +pattern of such abuse occurs in the area of products for individuals to
   12.58 +use, which is precisely where it is most unacceptable.  Therefore, we
   12.59 +have designed this version of the GPL to prohibit the practice for those
   12.60 +products.  If such problems arise substantially in other domains, we
   12.61 +stand ready to extend this provision to those domains in future versions
   12.62 +of the GPL, as needed to protect the freedom of users.
   12.63 +
   12.64 +  Finally, every program is threatened constantly by software patents.
   12.65 +States should not allow patents to restrict development and use of
   12.66 +software on general-purpose computers, but in those that do, we wish to
   12.67 +avoid the special danger that patents applied to a free program could
   12.68 +make it effectively proprietary.  To prevent this, the GPL assures that
   12.69 +patents cannot be used to render the program non-free.
   12.70 +
   12.71 +  The precise terms and conditions for copying, distribution and
   12.72 +modification follow.
   12.73 +
   12.74 +                       TERMS AND CONDITIONS
   12.75 +
   12.76 +  0. Definitions.
   12.77 +
   12.78 +  "This License" refers to version 3 of the GNU General Public License.
   12.79 +
   12.80 +  "Copyright" also means copyright-like laws that apply to other kinds of
   12.81 +works, such as semiconductor masks.
   12.82 +
   12.83 +  "The Program" refers to any copyrightable work licensed under this
   12.84 +License.  Each licensee is addressed as "you".  "Licensees" and
   12.85 +"recipients" may be individuals or organizations.
   12.86 +
   12.87 +  To "modify" a work means to copy from or adapt all or part of the work
   12.88 +in a fashion requiring copyright permission, other than the making of an
   12.89 +exact copy.  The resulting work is called a "modified version" of the
   12.90 +earlier work or a work "based on" the earlier work.
   12.91 +
   12.92 +  A "covered work" means either the unmodified Program or a work based
   12.93 +on the Program.
   12.94 +
   12.95 +  To "propagate" a work means to do anything with it that, without
   12.96 +permission, would make you directly or secondarily liable for
   12.97 +infringement under applicable copyright law, except executing it on a
   12.98 +computer or modifying a private copy.  Propagation includes copying,
   12.99 +distribution (with or without modification), making available to the
  12.100 +public, and in some countries other activities as well.
  12.101 +
  12.102 +  To "convey" a work means any kind of propagation that enables other
  12.103 +parties to make or receive copies.  Mere interaction with a user through
  12.104 +a computer network, with no transfer of a copy, is not conveying.
  12.105 +
  12.106 +  An interactive user interface displays "Appropriate Legal Notices"
  12.107 +to the extent that it includes a convenient and prominently visible
  12.108 +feature that (1) displays an appropriate copyright notice, and (2)
  12.109 +tells the user that there is no warranty for the work (except to the
  12.110 +extent that warranties are provided), that licensees may convey the
  12.111 +work under this License, and how to view a copy of this License.  If
  12.112 +the interface presents a list of user commands or options, such as a
  12.113 +menu, a prominent item in the list meets this criterion.
  12.114 +
  12.115 +  1. Source Code.
  12.116 +
  12.117 +  The "source code" for a work means the preferred form of the work
  12.118 +for making modifications to it.  "Object code" means any non-source
  12.119 +form of a work.
  12.120 +
  12.121 +  A "Standard Interface" means an interface that either is an official
  12.122 +standard defined by a recognized standards body, or, in the case of
  12.123 +interfaces specified for a particular programming language, one that
  12.124 +is widely used among developers working in that language.
  12.125 +
  12.126 +  The "System Libraries" of an executable work include anything, other
  12.127 +than the work as a whole, that (a) is included in the normal form of
  12.128 +packaging a Major Component, but which is not part of that Major
  12.129 +Component, and (b) serves only to enable use of the work with that
  12.130 +Major Component, or to implement a Standard Interface for which an
  12.131 +implementation is available to the public in source code form.  A
  12.132 +"Major Component", in this context, means a major essential component
  12.133 +(kernel, window system, and so on) of the specific operating system
  12.134 +(if any) on which the executable work runs, or a compiler used to
  12.135 +produce the work, or an object code interpreter used to run it.
  12.136 +
  12.137 +  The "Corresponding Source" for a work in object code form means all
  12.138 +the source code needed to generate, install, and (for an executable
  12.139 +work) run the object code and to modify the work, including scripts to
  12.140 +control those activities.  However, it does not include the work's
  12.141 +System Libraries, or general-purpose tools or generally available free
  12.142 +programs which are used unmodified in performing those activities but
  12.143 +which are not part of the work.  For example, Corresponding Source
  12.144 +includes interface definition files associated with source files for
  12.145 +the work, and the source code for shared libraries and dynamically
  12.146 +linked subprograms that the work is specifically designed to require,
  12.147 +such as by intimate data communication or control flow between those
  12.148 +subprograms and other parts of the work.
  12.149 +
  12.150 +  The Corresponding Source need not include anything that users
  12.151 +can regenerate automatically from other parts of the Corresponding
  12.152 +Source.
  12.153 +
  12.154 +  The Corresponding Source for a work in source code form is that
  12.155 +same work.
  12.156 +
  12.157 +  2. Basic Permissions.
  12.158 +
  12.159 +  All rights granted under this License are granted for the term of
  12.160 +copyright on the Program, and are irrevocable provided the stated
  12.161 +conditions are met.  This License explicitly affirms your unlimited
  12.162 +permission to run the unmodified Program.  The output from running a
  12.163 +covered work is covered by this License only if the output, given its
  12.164 +content, constitutes a covered work.  This License acknowledges your
  12.165 +rights of fair use or other equivalent, as provided by copyright law.
  12.166 +
  12.167 +  You may make, run and propagate covered works that you do not
  12.168 +convey, without conditions so long as your license otherwise remains
  12.169 +in force.  You may convey covered works to others for the sole purpose
  12.170 +of having them make modifications exclusively for you, or provide you
  12.171 +with facilities for running those works, provided that you comply with
  12.172 +the terms of this License in conveying all material for which you do
  12.173 +not control copyright.  Those thus making or running the covered works
  12.174 +for you must do so exclusively on your behalf, under your direction
  12.175 +and control, on terms that prohibit them from making any copies of
  12.176 +your copyrighted material outside their relationship with you.
  12.177 +
  12.178 +  Conveying under any other circumstances is permitted solely under
  12.179 +the conditions stated below.  Sublicensing is not allowed; section 10
  12.180 +makes it unnecessary.
  12.181 +
  12.182 +  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
  12.183 +
  12.184 +  No covered work shall be deemed part of an effective technological
  12.185 +measure under any applicable law fulfilling obligations under article
  12.186 +11 of the WIPO copyright treaty adopted on 20 December 1996, or
  12.187 +similar laws prohibiting or restricting circumvention of such
  12.188 +measures.
  12.189 +
  12.190 +  When you convey a covered work, you waive any legal power to forbid
  12.191 +circumvention of technological measures to the extent such circumvention
  12.192 +is effected by exercising rights under this License with respect to
  12.193 +the covered work, and you disclaim any intention to limit operation or
  12.194 +modification of the work as a means of enforcing, against the work's
  12.195 +users, your or third parties' legal rights to forbid circumvention of
  12.196 +technological measures.
  12.197 +
  12.198 +  4. Conveying Verbatim Copies.
  12.199 +
  12.200 +  You may convey verbatim copies of the Program's source code as you
  12.201 +receive it, in any medium, provided that you conspicuously and
  12.202 +appropriately publish on each copy an appropriate copyright notice;
  12.203 +keep intact all notices stating that this License and any
  12.204 +non-permissive terms added in accord with section 7 apply to the code;
  12.205 +keep intact all notices of the absence of any warranty; and give all
  12.206 +recipients a copy of this License along with the Program.
  12.207 +
  12.208 +  You may charge any price or no price for each copy that you convey,
  12.209 +and you may offer support or warranty protection for a fee.
  12.210 +
  12.211 +  5. Conveying Modified Source Versions.
  12.212 +
  12.213 +  You may convey a work based on the Program, or the modifications to
  12.214 +produce it from the Program, in the form of source code under the
  12.215 +terms of section 4, provided that you also meet all of these conditions:
  12.216 +
  12.217 +    a) The work must carry prominent notices stating that you modified
  12.218 +    it, and giving a relevant date.
  12.219 +
  12.220 +    b) The work must carry prominent notices stating that it is
  12.221 +    released under this License and any conditions added under section
  12.222 +    7.  This requirement modifies the requirement in section 4 to
  12.223 +    "keep intact all notices".
  12.224 +
  12.225 +    c) You must license the entire work, as a whole, under this
  12.226 +    License to anyone who comes into possession of a copy.  This
  12.227 +    License will therefore apply, along with any applicable section 7
  12.228 +    additional terms, to the whole of the work, and all its parts,
  12.229 +    regardless of how they are packaged.  This License gives no
  12.230 +    permission to license the work in any other way, but it does not
  12.231 +    invalidate such permission if you have separately received it.
  12.232 +
  12.233 +    d) If the work has interactive user interfaces, each must display
  12.234 +    Appropriate Legal Notices; however, if the Program has interactive
  12.235 +    interfaces that do not display Appropriate Legal Notices, your
  12.236 +    work need not make them do so.
  12.237 +
  12.238 +  A compilation of a covered work with other separate and independent
  12.239 +works, which are not by their nature extensions of the covered work,
  12.240 +and which are not combined with it such as to form a larger program,
  12.241 +in or on a volume of a storage or distribution medium, is called an
  12.242 +"aggregate" if the compilation and its resulting copyright are not
  12.243 +used to limit the access or legal rights of the compilation's users
  12.244 +beyond what the individual works permit.  Inclusion of a covered work
  12.245 +in an aggregate does not cause this License to apply to the other
  12.246 +parts of the aggregate.
  12.247 +
  12.248 +  6. Conveying Non-Source Forms.
  12.249 +
  12.250 +  You may convey a covered work in object code form under the terms
  12.251 +of sections 4 and 5, provided that you also convey the
  12.252 +machine-readable Corresponding Source under the terms of this License,
  12.253 +in one of these ways:
  12.254 +
  12.255 +    a) Convey the object code in, or embodied in, a physical product
  12.256 +    (including a physical distribution medium), accompanied by the
  12.257 +    Corresponding Source fixed on a durable physical medium
  12.258 +    customarily used for software interchange.
  12.259 +
  12.260 +    b) Convey the object code in, or embodied in, a physical product
  12.261 +    (including a physical distribution medium), accompanied by a
  12.262 +    written offer, valid for at least three years and valid for as
  12.263 +    long as you offer spare parts or customer support for that product
  12.264 +    model, to give anyone who possesses the object code either (1) a
  12.265 +    copy of the Corresponding Source for all the software in the
  12.266 +    product that is covered by this License, on a durable physical
  12.267 +    medium customarily used for software interchange, for a price no
  12.268 +    more than your reasonable cost of physically performing this
  12.269 +    conveying of source, or (2) access to copy the
  12.270 +    Corresponding Source from a network server at no charge.
  12.271 +
  12.272 +    c) Convey individual copies of the object code with a copy of the
  12.273 +    written offer to provide the Corresponding Source.  This
  12.274 +    alternative is allowed only occasionally and noncommercially, and
  12.275 +    only if you received the object code with such an offer, in accord
  12.276 +    with subsection 6b.
  12.277 +
  12.278 +    d) Convey the object code by offering access from a designated
  12.279 +    place (gratis or for a charge), and offer equivalent access to the
  12.280 +    Corresponding Source in the same way through the same place at no
  12.281 +    further charge.  You need not require recipients to copy the
  12.282 +    Corresponding Source along with the object code.  If the place to
  12.283 +    copy the object code is a network server, the Corresponding Source
  12.284 +    may be on a different server (operated by you or a third party)
  12.285 +    that supports equivalent copying facilities, provided you maintain
  12.286 +    clear directions next to the object code saying where to find the
  12.287 +    Corresponding Source.  Regardless of what server hosts the
  12.288 +    Corresponding Source, you remain obligated to ensure that it is
  12.289 +    available for as long as needed to satisfy these requirements.
  12.290 +
  12.291 +    e) Convey the object code using peer-to-peer transmission, provided
  12.292 +    you inform other peers where the object code and Corresponding
  12.293 +    Source of the work are being offered to the general public at no
  12.294 +    charge under subsection 6d.
  12.295 +
  12.296 +  A separable portion of the object code, whose source code is excluded
  12.297 +from the Corresponding Source as a System Library, need not be
  12.298 +included in conveying the object code work.
  12.299 +
  12.300 +  A "User Product" is either (1) a "consumer product", which means any
  12.301 +tangible personal property which is normally used for personal, family,
  12.302 +or household purposes, or (2) anything designed or sold for incorporation
  12.303 +into a dwelling.  In determining whether a product is a consumer product,
  12.304 +doubtful cases shall be resolved in favor of coverage.  For a particular
  12.305 +product received by a particular user, "normally used" refers to a
  12.306 +typical or common use of that class of product, regardless of the status
  12.307 +of the particular user or of the way in which the particular user
  12.308 +actually uses, or expects or is expected to use, the product.  A product
  12.309 +is a consumer product regardless of whether the product has substantial
  12.310 +commercial, industrial or non-consumer uses, unless such uses represent
  12.311 +the only significant mode of use of the product.
  12.312 +
  12.313 +  "Installation Information" for a User Product means any methods,
  12.314 +procedures, authorization keys, or other information required to install
  12.315 +and execute modified versions of a covered work in that User Product from
  12.316 +a modified version of its Corresponding Source.  The information must
  12.317 +suffice to ensure that the continued functioning of the modified object
  12.318 +code is in no case prevented or interfered with solely because
  12.319 +modification has been made.
  12.320 +
  12.321 +  If you convey an object code work under this section in, or with, or
  12.322 +specifically for use in, a User Product, and the conveying occurs as
  12.323 +part of a transaction in which the right of possession and use of the
  12.324 +User Product is transferred to the recipient in perpetuity or for a
  12.325 +fixed term (regardless of how the transaction is characterized), the
  12.326 +Corresponding Source conveyed under this section must be accompanied
  12.327 +by the Installation Information.  But this requirement does not apply
  12.328 +if neither you nor any third party retains the ability to install
  12.329 +modified object code on the User Product (for example, the work has
  12.330 +been installed in ROM).
  12.331 +
  12.332 +  The requirement to provide Installation Information does not include a
  12.333 +requirement to continue to provide support service, warranty, or updates
  12.334 +for a work that has been modified or installed by the recipient, or for
  12.335 +the User Product in which it has been modified or installed.  Access to a
  12.336 +network may be denied when the modification itself materially and
  12.337 +adversely affects the operation of the network or violates the rules and
  12.338 +protocols for communication across the network.
  12.339 +
  12.340 +  Corresponding Source conveyed, and Installation Information provided,
  12.341 +in accord with this section must be in a format that is publicly
  12.342 +documented (and with an implementation available to the public in
  12.343 +source code form), and must require no special password or key for
  12.344 +unpacking, reading or copying.
  12.345 +
  12.346 +  7. Additional Terms.
  12.347 +
  12.348 +  "Additional permissions" are terms that supplement the terms of this
  12.349 +License by making exceptions from one or more of its conditions.
  12.350 +Additional permissions that are applicable to the entire Program shall
  12.351 +be treated as though they were included in this License, to the extent
  12.352 +that they are valid under applicable law.  If additional permissions
  12.353 +apply only to part of the Program, that part may be used separately
  12.354 +under those permissions, but the entire Program remains governed by
  12.355 +this License without regard to the additional permissions.
  12.356 +
  12.357 +  When you convey a copy of a covered work, you may at your option
  12.358 +remove any additional permissions from that copy, or from any part of
  12.359 +it.  (Additional permissions may be written to require their own
  12.360 +removal in certain cases when you modify the work.)  You may place
  12.361 +additional permissions on material, added by you to a covered work,
  12.362 +for which you have or can give appropriate copyright permission.
  12.363 +
  12.364 +  Notwithstanding any other provision of this License, for material you
  12.365 +add to a covered work, you may (if authorized by the copyright holders of
  12.366 +that material) supplement the terms of this License with terms:
  12.367 +
  12.368 +    a) Disclaiming warranty or limiting liability differently from the
  12.369 +    terms of sections 15 and 16 of this License; or
  12.370 +
  12.371 +    b) Requiring preservation of specified reasonable legal notices or
  12.372 +    author attributions in that material or in the Appropriate Legal
  12.373 +    Notices displayed by works containing it; or
  12.374 +
  12.375 +    c) Prohibiting misrepresentation of the origin of that material, or
  12.376 +    requiring that modified versions of such material be marked in
  12.377 +    reasonable ways as different from the original version; or
  12.378 +
  12.379 +    d) Limiting the use for publicity purposes of names of licensors or
  12.380 +    authors of the material; or
  12.381 +
  12.382 +    e) Declining to grant rights under trademark law for use of some
  12.383 +    trade names, trademarks, or service marks; or
  12.384 +
  12.385 +    f) Requiring indemnification of licensors and authors of that
  12.386 +    material by anyone who conveys the material (or modified versions of
  12.387 +    it) with contractual assumptions of liability to the recipient, for
  12.388 +    any liability that these contractual assumptions directly impose on
  12.389 +    those licensors and authors.
  12.390 +
  12.391 +  All other non-permissive additional terms are considered "further
  12.392 +restrictions" within the meaning of section 10.  If the Program as you
  12.393 +received it, or any part of it, contains a notice stating that it is
  12.394 +governed by this License along with a term that is a further
  12.395 +restriction, you may remove that term.  If a license document contains
  12.396 +a further restriction but permits relicensing or conveying under this
  12.397 +License, you may add to a covered work material governed by the terms
  12.398 +of that license document, provided that the further restriction does
  12.399 +not survive such relicensing or conveying.
  12.400 +
  12.401 +  If you add terms to a covered work in accord with this section, you
  12.402 +must place, in the relevant source files, a statement of the
  12.403 +additional terms that apply to those files, or a notice indicating
  12.404 +where to find the applicable terms.
  12.405 +
  12.406 +  Additional terms, permissive or non-permissive, may be stated in the
  12.407 +form of a separately written license, or stated as exceptions;
  12.408 +the above requirements apply either way.
  12.409 +
  12.410 +  8. Termination.
  12.411 +
  12.412 +  You may not propagate or modify a covered work except as expressly
  12.413 +provided under this License.  Any attempt otherwise to propagate or
  12.414 +modify it is void, and will automatically terminate your rights under
  12.415 +this License (including any patent licenses granted under the third
  12.416 +paragraph of section 11).
  12.417 +
  12.418 +  However, if you cease all violation of this License, then your
  12.419 +license from a particular copyright holder is reinstated (a)
  12.420 +provisionally, unless and until the copyright holder explicitly and
  12.421 +finally terminates your license, and (b) permanently, if the copyright
  12.422 +holder fails to notify you of the violation by some reasonable means
  12.423 +prior to 60 days after the cessation.
  12.424 +
  12.425 +  Moreover, your license from a particular copyright holder is
  12.426 +reinstated permanently if the copyright holder notifies you of the
  12.427 +violation by some reasonable means, this is the first time you have
  12.428 +received notice of violation of this License (for any work) from that
  12.429 +copyright holder, and you cure the violation prior to 30 days after
  12.430 +your receipt of the notice.
  12.431 +
  12.432 +  Termination of your rights under this section does not terminate the
  12.433 +licenses of parties who have received copies or rights from you under
  12.434 +this License.  If your rights have been terminated and not permanently
  12.435 +reinstated, you do not qualify to receive new licenses for the same
  12.436 +material under section 10.
  12.437 +
  12.438 +  9. Acceptance Not Required for Having Copies.
  12.439 +
  12.440 +  You are not required to accept this License in order to receive or
  12.441 +run a copy of the Program.  Ancillary propagation of a covered work
  12.442 +occurring solely as a consequence of using peer-to-peer transmission
  12.443 +to receive a copy likewise does not require acceptance.  However,
  12.444 +nothing other than this License grants you permission to propagate or
  12.445 +modify any covered work.  These actions infringe copyright if you do
  12.446 +not accept this License.  Therefore, by modifying or propagating a
  12.447 +covered work, you indicate your acceptance of this License to do so.
  12.448 +
  12.449 +  10. Automatic Licensing of Downstream Recipients.
  12.450 +
  12.451 +  Each time you convey a covered work, the recipient automatically
  12.452 +receives a license from the original licensors, to run, modify and
  12.453 +propagate that work, subject to this License.  You are not responsible
  12.454 +for enforcing compliance by third parties with this License.
  12.455 +
  12.456 +  An "entity transaction" is a transaction transferring control of an
  12.457 +organization, or substantially all assets of one, or subdividing an
  12.458 +organization, or merging organizations.  If propagation of a covered
  12.459 +work results from an entity transaction, each party to that
  12.460 +transaction who receives a copy of the work also receives whatever
  12.461 +licenses to the work the party's predecessor in interest had or could
  12.462 +give under the previous paragraph, plus a right to possession of the
  12.463 +Corresponding Source of the work from the predecessor in interest, if
  12.464 +the predecessor has it or can get it with reasonable efforts.
  12.465 +
  12.466 +  You may not impose any further restrictions on the exercise of the
  12.467 +rights granted or affirmed under this License.  For example, you may
  12.468 +not impose a license fee, royalty, or other charge for exercise of
  12.469 +rights granted under this License, and you may not initiate litigation
  12.470 +(including a cross-claim or counterclaim in a lawsuit) alleging that
  12.471 +any patent claim is infringed by making, using, selling, offering for
  12.472 +sale, or importing the Program or any portion of it.
  12.473 +
  12.474 +  11. Patents.
  12.475 +
  12.476 +  A "contributor" is a copyright holder who authorizes use under this
  12.477 +License of the Program or a work on which the Program is based.  The
  12.478 +work thus licensed is called the contributor's "contributor version".
  12.479 +
  12.480 +  A contributor's "essential patent claims" are all patent claims
  12.481 +owned or controlled by the contributor, whether already acquired or
  12.482 +hereafter acquired, that would be infringed by some manner, permitted
  12.483 +by this License, of making, using, or selling its contributor version,
  12.484 +but do not include claims that would be infringed only as a
  12.485 +consequence of further modification of the contributor version.  For
  12.486 +purposes of this definition, "control" includes the right to grant
  12.487 +patent sublicenses in a manner consistent with the requirements of
  12.488 +this License.
  12.489 +
  12.490 +  Each contributor grants you a non-exclusive, worldwide, royalty-free
  12.491 +patent license under the contributor's essential patent claims, to
  12.492 +make, use, sell, offer for sale, import and otherwise run, modify and
  12.493 +propagate the contents of its contributor version.
  12.494 +
  12.495 +  In the following three paragraphs, a "patent license" is any express
  12.496 +agreement or commitment, however denominated, not to enforce a patent
  12.497 +(such as an express permission to practice a patent or covenant not to
  12.498 +sue for patent infringement).  To "grant" such a patent license to a
  12.499 +party means to make such an agreement or commitment not to enforce a
  12.500 +patent against the party.
  12.501 +
  12.502 +  If you convey a covered work, knowingly relying on a patent license,
  12.503 +and the Corresponding Source of the work is not available for anyone
  12.504 +to copy, free of charge and under the terms of this License, through a
  12.505 +publicly available network server or other readily accessible means,
  12.506 +then you must either (1) cause the Corresponding Source to be so
  12.507 +available, or (2) arrange to deprive yourself of the benefit of the
  12.508 +patent license for this particular work, or (3) arrange, in a manner
  12.509 +consistent with the requirements of this License, to extend the patent
  12.510 +license to downstream recipients.  "Knowingly relying" means you have
  12.511 +actual knowledge that, but for the patent license, your conveying the
  12.512 +covered work in a country, or your recipient's use of the covered work
  12.513 +in a country, would infringe one or more identifiable patents in that
  12.514 +country that you have reason to believe are valid.
  12.515 +
  12.516 +  If, pursuant to or in connection with a single transaction or
  12.517 +arrangement, you convey, or propagate by procuring conveyance of, a
  12.518 +covered work, and grant a patent license to some of the parties
  12.519 +receiving the covered work authorizing them to use, propagate, modify
  12.520 +or convey a specific copy of the covered work, then the patent license
  12.521 +you grant is automatically extended to all recipients of the covered
  12.522 +work and works based on it.
  12.523 +
  12.524 +  A patent license is "discriminatory" if it does not include within
  12.525 +the scope of its coverage, prohibits the exercise of, or is
  12.526 +conditioned on the non-exercise of one or more of the rights that are
  12.527 +specifically granted under this License.  You may not convey a covered
  12.528 +work if you are a party to an arrangement with a third party that is
  12.529 +in the business of distributing software, under which you make payment
  12.530 +to the third party based on the extent of your activity of conveying
  12.531 +the work, and under which the third party grants, to any of the
  12.532 +parties who would receive the covered work from you, a discriminatory
  12.533 +patent license (a) in connection with copies of the covered work
  12.534 +conveyed by you (or copies made from those copies), or (b) primarily
  12.535 +for and in connection with specific products or compilations that
  12.536 +contain the covered work, unless you entered into that arrangement,
  12.537 +or that patent license was granted, prior to 28 March 2007.
  12.538 +
  12.539 +  Nothing in this License shall be construed as excluding or limiting
  12.540 +any implied license or other defenses to infringement that may
  12.541 +otherwise be available to you under applicable patent law.
  12.542 +
  12.543 +  12. No Surrender of Others' Freedom.
  12.544 +
  12.545 +  If conditions are imposed on you (whether by court order, agreement or
  12.546 +otherwise) that contradict the conditions of this License, they do not
  12.547 +excuse you from the conditions of this License.  If you cannot convey a
  12.548 +covered work so as to satisfy simultaneously your obligations under this
  12.549 +License and any other pertinent obligations, then as a consequence you may
  12.550 +not convey it at all.  For example, if you agree to terms that obligate you
  12.551 +to collect a royalty for further conveying from those to whom you convey
  12.552 +the Program, the only way you could satisfy both those terms and this
  12.553 +License would be to refrain entirely from conveying the Program.
  12.554 +
  12.555 +  13. Use with the GNU Affero General Public License.
  12.556 +
  12.557 +  Notwithstanding any other provision of this License, you have
  12.558 +permission to link or combine any covered work with a work licensed
  12.559 +under version 3 of the GNU Affero General Public License into a single
  12.560 +combined work, and to convey the resulting work.  The terms of this
  12.561 +License will continue to apply to the part which is the covered work,
  12.562 +but the special requirements of the GNU Affero General Public License,
  12.563 +section 13, concerning interaction through a network will apply to the
  12.564 +combination as such.
  12.565 +
  12.566 +  14. Revised Versions of this License.
  12.567 +
  12.568 +  The Free Software Foundation may publish revised and/or new versions of
  12.569 +the GNU General Public License from time to time.  Such new versions will
  12.570 +be similar in spirit to the present version, but may differ in detail to
  12.571 +address new problems or concerns.
  12.572 +
  12.573 +  Each version is given a distinguishing version number.  If the
  12.574 +Program specifies that a certain numbered version of the GNU General
  12.575 +Public License "or any later version" applies to it, you have the
  12.576 +option of following the terms and conditions either of that numbered
  12.577 +version or of any later version published by the Free Software
  12.578 +Foundation.  If the Program does not specify a version number of the
  12.579 +GNU General Public License, you may choose any version ever published
  12.580 +by the Free Software Foundation.
  12.581 +
  12.582 +  If the Program specifies that a proxy can decide which future
  12.583 +versions of the GNU General Public License can be used, that proxy's
  12.584 +public statement of acceptance of a version permanently authorizes you
  12.585 +to choose that version for the Program.
  12.586 +
  12.587 +  Later license versions may give you additional or different
  12.588 +permissions.  However, no additional obligations are imposed on any
  12.589 +author or copyright holder as a result of your choosing to follow a
  12.590 +later version.
  12.591 +
  12.592 +  15. Disclaimer of Warranty.
  12.593 +
  12.594 +  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
  12.595 +APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
  12.596 +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
  12.597 +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
  12.598 +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
  12.599 +PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
  12.600 +IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
  12.601 +ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  12.602 +
  12.603 +  16. Limitation of Liability.
  12.604 +
  12.605 +  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
  12.606 +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
  12.607 +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
  12.608 +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
  12.609 +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
  12.610 +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
  12.611 +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
  12.612 +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
  12.613 +SUCH DAMAGES.
  12.614 +
  12.615 +  17. Interpretation of Sections 15 and 16.
  12.616 +
  12.617 +  If the disclaimer of warranty and limitation of liability provided
  12.618 +above cannot be given local legal effect according to their terms,
  12.619 +reviewing courts shall apply local law that most closely approximates
  12.620 +an absolute waiver of all civil liability in connection with the
  12.621 +Program, unless a warranty or assumption of liability accompanies a
  12.622 +copy of the Program in return for a fee.
  12.623 +
  12.624 +                     END OF TERMS AND CONDITIONS
  12.625 +
  12.626 +            How to Apply These Terms to Your New Programs
  12.627 +
  12.628 +  If you develop a new program, and you want it to be of the greatest
  12.629 +possible use to the public, the best way to achieve this is to make it
  12.630 +free software which everyone can redistribute and change under these terms.
  12.631 +
  12.632 +  To do so, attach the following notices to the program.  It is safest
  12.633 +to attach them to the start of each source file to most effectively
  12.634 +state the exclusion of warranty; and each file should have at least
  12.635 +the "copyright" line and a pointer to where the full notice is found.
  12.636 +
  12.637 +    <one line to give the program's name and a brief idea of what it does.>
  12.638 +    Copyright (C) <year>  <name of author>
  12.639 +
  12.640 +    This program is free software: you can redistribute it and/or modify
  12.641 +    it under the terms of the GNU General Public License as published by
  12.642 +    the Free Software Foundation, either version 3 of the License, or
  12.643 +    (at your option) any later version.
  12.644 +
  12.645 +    This program is distributed in the hope that it will be useful,
  12.646 +    but WITHOUT ANY WARRANTY; without even the implied warranty of
  12.647 +    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
  12.648 +    GNU General Public License for more details.
  12.649 +
  12.650 +    You should have received a copy of the GNU General Public License
  12.651 +    along with this program.  If not, see <http://www.gnu.org/licenses/>.
  12.652 +
  12.653 +Also add information on how to contact you by electronic and paper mail.
  12.654 +
  12.655 +  If the program does terminal interaction, make it output a short
  12.656 +notice like this when it starts in an interactive mode:
  12.657 +
  12.658 +    <program>  Copyright (C) <year>  <name of author>
  12.659 +    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
  12.660 +    This is free software, and you are welcome to redistribute it
  12.661 +    under certain conditions; type `show c' for details.
  12.662 +
  12.663 +The hypothetical commands `show w' and `show c' should show the appropriate
  12.664 +parts of the General Public License.  Of course, your program's commands
  12.665 +might be different; for a GUI interface, you would use an "about box".
  12.666 +
  12.667 +  You should also get your employer (if you work as a programmer) or school,
  12.668 +if any, to sign a "copyright disclaimer" for the program, if necessary.
  12.669 +For more information on this, and how to apply and follow the GNU GPL, see
  12.670 +<http://www.gnu.org/licenses/>.
  12.671 +
  12.672 +  The GNU General Public License does not permit incorporating your program
  12.673 +into proprietary programs.  If your program is a subroutine library, you
  12.674 +may consider it more useful to permit linking proprietary applications with
  12.675 +the library.  If this is what you want to do, use the GNU Lesser General
  12.676 +Public License instead of this License.  But first, please read
  12.677 +<http://www.gnu.org/philosophy/why-not-lgpl.html>.

    13.6 +
    13.7 + Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
    13.8 + Everyone is permitted to copy and distribute verbatim copies
    13.9 + of this license document, but changing it is not allowed.
   13.10 +
   13.11 +
   13.12 +  This version of the GNU Lesser General Public License incorporates
   13.13 +the terms and conditions of version 3 of the GNU General Public
   13.14 +License, supplemented by the additional permissions listed below.
   13.15 +
   13.16 +  0. Additional Definitions.
   13.17 +
   13.18 +  As used herein, "this License" refers to version 3 of the GNU Lesser
   13.19 +General Public License, and the "GNU GPL" refers to version 3 of the GNU
   13.20 +General Public License.
   13.21 +
   13.22 +  "The Library" refers to a covered work governed by this License,
   13.23 +other than an Application or a Combined Work as defined below.
   13.24 +
   13.25 +  An "Application" is any work that makes use of an interface provided
   13.26 +by the Library, but which is not otherwise based on the Library.
   13.27 +Defining a subclass of a class defined by the Library is deemed a mode
   13.28 +of using an interface provided by the Library.
   13.29 +
   13.30 +  A "Combined Work" is a work produced by combining or linking an
   13.31 +Application with the Library.  The particular version of the Library
   13.32 +with which the Combined Work was made is also called the "Linked
   13.33 +Version".
   13.34 +
   13.35 +  The "Minimal Corresponding Source" for a Combined Work means the
   13.36 +Corresponding Source for the Combined Work, excluding any source code
   13.37 +for portions of the Combined Work that, considered in isolation, are
   13.38 +based on the Application, and not on the Linked Version.
   13.39 +
   13.40 +  The "Corresponding Application Code" for a Combined Work means the
   13.41 +object code and/or source code for the Application, including any data
   13.42 +and utility programs needed for reproducing the Combined Work from the
   13.43 +Application, but excluding the System Libraries of the Combined Work.
   13.44 +
   13.45 +  1. Exception to Section 3 of the GNU GPL.
   13.46 +
   13.47 +  You may convey a covered work under sections 3 and 4 of this License
   13.48 +without being bound by section 3 of the GNU GPL.
   13.49 +
   13.50 +  2. Conveying Modified Versions.
   13.51 +
   13.52 +  If you modify a copy of the Library, and, in your modifications, a
   13.53 +facility refers to a function or data to be supplied by an Application
   13.54 +that uses the facility (other than as an argument passed when the
   13.55 +facility is invoked), then you may convey a copy of the modified
   13.56 +version:
   13.57 +
   13.58 +   a) under this License, provided that you make a good faith effort to
   13.59 +   ensure that, in the event an Application does not supply the
   13.60 +   function or data, the facility still operates, and performs
   13.61 +   whatever part of its purpose remains meaningful, or
   13.62 +
   13.63 +   b) under the GNU GPL, with none of the additional permissions of
   13.64 +   this License applicable to that copy.
   13.65 +
   13.66 +  3. Object Code Incorporating Material from Library Header Files.
   13.67 +
   13.68 +  The object code form of an Application may incorporate material from
   13.69 +a header file that is part of the Library.  You may convey such object
   13.70 +code under terms of your choice, provided that, if the incorporated
   13.71 +material is not limited to numerical parameters, data structure
   13.72 +layouts and accessors, or small macros, inline functions and templates
   13.73 +(ten or fewer lines in length), you do both of the following:
   13.74 +
   13.75 +   a) Give prominent notice with each copy of the object code that the
   13.76 +   Library is used in it and that the Library and its use are
   13.77 +   covered by this License.
   13.78 +
   13.79 +   b) Accompany the object code with a copy of the GNU GPL and this license
   13.80 +   document.
   13.81 +
   13.82 +  4. Combined Works.
   13.83 +
   13.84 +  You may convey a Combined Work under terms of your choice that,
   13.85 +taken together, effectively do not restrict modification of the
   13.86 +portions of the Library contained in the Combined Work and reverse
   13.87 +engineering for debugging such modifications, if you also do each of
   13.88 +the following:
   13.89 +
   13.90 +   a) Give prominent notice with each copy of the Combined Work that
   13.91 +   the Library is used in it and that the Library and its use are
   13.92 +   covered by this License.
   13.93 +
   13.94 +   b) Accompany the Combined Work with a copy of the GNU GPL and this license
   13.95 +   document.
   13.96 +
   13.97 +   c) For a Combined Work that displays copyright notices during
   13.98 +   execution, include the copyright notice for the Library among
   13.99 +   these notices, as well as a reference directing the user to the
  13.100 +   copies of the GNU GPL and this license document.
  13.101 +
  13.102 +   d) Do one of the following:
  13.103 +
  13.104 +       0) Convey the Minimal Corresponding Source under the terms of this
  13.105 +       License, and the Corresponding Application Code in a form
  13.106 +       suitable for, and under terms that permit, the user to
  13.107 +       recombine or relink the Application with a modified version of
  13.108 +       the Linked Version to produce a modified Combined Work, in the
  13.109 +       manner specified by section 6 of the GNU GPL for conveying
  13.110 +       Corresponding Source.
  13.111 +
  13.112 +       1) Use a suitable shared library mechanism for linking with the
  13.113 +       Library.  A suitable mechanism is one that (a) uses at run time
  13.114 +       a copy of the Library already present on the user's computer
  13.115 +       system, and (b) will operate properly with a modified version
  13.116 +       of the Library that is interface-compatible with the Linked
  13.117 +       Version.
  13.118 +
  13.119 +   e) Provide Installation Information, but only if you would otherwise
  13.120 +   be required to provide such information under section 6 of the
  13.121 +   GNU GPL, and only to the extent that such information is
  13.122 +   necessary to install and execute a modified version of the
  13.123 +   Combined Work produced by recombining or relinking the
  13.124 +   Application with a modified version of the Linked Version. (If
  13.125 +   you use option 4d0, the Installation Information must accompany
  13.126 +   the Minimal Corresponding Source and Corresponding Application
  13.127 +   Code. If you use option 4d1, you must provide the Installation
  13.128 +   Information in the manner specified by section 6 of the GNU GPL
  13.129 +   for conveying Corresponding Source.)
  13.130 +
  13.131 +  5. Combined Libraries.
  13.132 +
  13.133 +  You may place library facilities that are a work based on the
  13.134 +Library side by side in a single library together with other library
  13.135 +facilities that are not Applications and are not covered by this
  13.136 +License, and convey such a combined library under terms of your
  13.137 +choice, if you do both of the following:
  13.138 +
  13.139 +   a) Accompany the combined library with a copy of the same work based
  13.140 +   on the Library, uncombined with any other library facilities,
  13.141 +   conveyed under the terms of this License.
  13.142 +
  13.143 +   b) Give prominent notice with the combined library that part of it
  13.144 +   is a work based on the Library, and explaining where to find the
  13.145 +   accompanying uncombined form of the same work.
  13.146 +
  13.147 +  6. Revised Versions of the GNU Lesser General Public License.
  13.148 +
  13.149 +  The Free Software Foundation may publish revised and/or new versions
  13.150 +of the GNU Lesser General Public License from time to time. Such new
  13.151 +versions will be similar in spirit to the present version, but may
  13.152 +differ in detail to address new problems or concerns.
  13.153 +
  13.154 +  Each version is given a distinguishing version number. If the
  13.155 +Library as you received it specifies that a certain numbered version
  13.156 +of the GNU Lesser General Public License "or any later version"
  13.157 +applies to it, you have the option of following the terms and
  13.158 +conditions either of that published version or of any later version
  13.159 +published by the Free Software Foundation. If the Library as you
  13.160 +received it does not specify a version number of the GNU Lesser
  13.161 +General Public License, you may choose any version of the GNU Lesser
  13.162 +General Public License ever published by the Free Software Foundation.
  13.163 +
  13.164 +  If the Library as you received it specifies that a proxy can decide
  13.165 +whether future versions of the GNU Lesser General Public License shall
  13.166 +apply, that proxy's public statement of acceptance of any version is
  13.167 +permanent authorization for you to choose that version for the
  13.168 +Library.

    14.4 +metasurf - a library for implicit surface polygonization
    14.5 +
    14.6 +1. Overview
    14.7 +-----------
    14.8 +
    14.9 +Metasurf is a library for implict surface polygonization. You only need to
   14.10 +set a callback that returns the scalar field value at any given point in
   14.11 +3-space, and another callback to accept isosurface vertices. Then at any point
   14.12 +just call msurf_polygonize, and the library handles everything else for you.
   14.13 +
   14.14 +2. Usage
   14.15 +--------
   14.16 +The following snippet is sufficient to draw the surface of an implicit unit
   14.17 +sphere, centered around the origin.
   14.18 +
   14.19 +     struct metasurface *ms;
   14.20 +     
   14.21 +     /* initialization */
   14.22 +     ms = msurf_create();
   14.23 +     msurf_eval_func(ms, eval);
   14.24 +     msurf_vertex_func(ms, glVertex3f);
   14.25 +     
   14.26 +     /* drawing */
   14.27 +     glBegin(GL_TRIANGLES);
   14.28 +     msurf_polygonize(ms);
   14.29 +     glEnd();
   14.30 +     
   14.31 +     /* evaluator */
   14.32 +     float eval(float x, float y, float z)
   14.33 +     {
   14.34 +         return (x * x + y * y + z * z) - 1.0;
   14.35 +     }
   14.36 +
   14.37 +See the examples subdirectory for more examples.
