0011 <h3 style="text-align: center;">GNU GENERAL PUBLIC LICENSE</h3>
0012 <p style="text-align: center;">Version 3, 29 June 2007</p>
0013 
0014 <p>Copyright &copy; 2007 Free Software Foundation, Inc.
0015  &lt;<a href="http://fsf.org/">http://fsf.org/</a>&gt;</p><p>
0016  Everyone is permitted to copy and distribute verbatim copies
0017  of this license document, but changing it is not allowed.</p>
0018 
0019 <h3><a name="preamble"></a>Preamble</h3>
0020 
0021 <p>The GNU General Public License is a free, copyleft license for
0022 software and other kinds of works.</p>
0023 
0024 <p>The licenses for most software and other practical works are designed
0025 to take away your freedom to share and change the works.  By contrast,
0026 the GNU General Public License is intended to guarantee your freedom to
0027 share and change all versions of a program--to make sure it remains free
0028 software for all its users.  We, the Free Software Foundation, use the
0029 GNU General Public License for most of our software; it applies also to
0030 any other work released this way by its authors.  You can apply it to
0031 your programs, too.</p>
0032 
0033 <p>When we speak of free software, we are referring to freedom, not
0034 price.  Our General Public Licenses are designed to make sure that you
0035 have the freedom to distribute copies of free software (and charge for
0036 them if you wish), that you receive source code or can get it if you
0037 want it, that you can change the software or use pieces of it in new
0038 free programs, and that you know you can do these things.</p>
0039 
0040 <p>To protect your rights, we need to prevent others from denying you
0041 these rights or asking you to surrender the rights.  Therefore, you have
0042 certain responsibilities if you distribute copies of the software, or if
0043 you modify it: responsibilities to respect the freedom of others.</p>
0044 
0045 <p>For example, if you distribute copies of such a program, whether
0046 gratis or for a fee, you must pass on to the recipients the same
0047 freedoms that you received.  You must make sure that they, too, receive
0048 or can get the source code.  And you must show them these terms so they
0049 know their rights.</p>
0050 
0051 <p>Developers that use the GNU GPL protect your rights with two steps:
0052 (1) assert copyright on the software, and (2) offer you this License
0053 giving you legal permission to copy, distribute and/or modify it.</p>
0054 
0055 <p>For the developers' and authors' protection, the GPL clearly explains
0056 that there is no warranty for this free software.  For both users' and
0057 authors' sake, the GPL requires that modified versions be marked as
0058 changed, so that their problems will not be attributed erroneously to
0059 authors of previous versions.</p>
0060 
0061 <p>Some devices are designed to deny users access to install or run
0062 modified versions of the software inside them, although the manufacturer
0063 can do so.  This is fundamentally incompatible with the aim of
0064 protecting users' freedom to change the software.  The systematic
0065 pattern of such abuse occurs in the area of products for individuals to
0066 use, which is precisely where it is most unacceptable.  Therefore, we
0067 have designed this version of the GPL to prohibit the practice for those
0068 products.  If such problems arise substantially in other domains, we
0069 stand ready to extend this provision to those domains in future versions
0070 of the GPL, as needed to protect the freedom of users.</p>
0071 
0072 <p>Finally, every program is threatened constantly by software patents.
0073 States should not allow patents to restrict development and use of
0074 software on general-purpose computers, but in those that do, we wish to
0075 avoid the special danger that patents applied to a free program could
0076 make it effectively proprietary.  To prevent this, the GPL assures that
0077 patents cannot be used to render the program non-free.</p>
0078 
0079 <p>The precise terms and conditions for copying, distribution and
0080 modification follow.</p>
0081 
0082 <h3><a name="terms"></a>TERMS AND CONDITIONS</h3>
0083 
0084 <h4><a name="section0"></a>0. Definitions.</h4>
0085 
0086 <p>&ldquo;This License&rdquo; refers to version 3 of the GNU General Public License.</p>
0087 
0088 <p>&ldquo;Copyright&rdquo; also means copyright-like laws that apply to other kinds of
0089 works, such as semiconductor masks.</p>
0090  
0091 <p>&ldquo;The Program&rdquo; refers to any copyrightable work licensed under this
0092 License.  Each licensee is addressed as &ldquo;you&rdquo;.  &ldquo;Licensees&rdquo; and
0093 &ldquo;recipients&rdquo; may be individuals or organizations.</p>
0094 
0095 <p>To &ldquo;modify&rdquo; a work means to copy from or adapt all or part of the work
0096 in a fashion requiring copyright permission, other than the making of an
0097 exact copy.  The resulting work is called a &ldquo;modified version&rdquo; of the
0098 earlier work or a work &ldquo;based on&rdquo; the earlier work.</p>
0099 
0100 <p>A &ldquo;covered work&rdquo; means either the unmodified Program or a work based
0101 on the Program.</p>
0102 
0103 <p>To &ldquo;propagate&rdquo; a work means to do anything with it that, without
0104 permission, would make you directly or secondarily liable for
0105 infringement under applicable copyright law, except executing it on a
0106 computer or modifying a private copy.  Propagation includes copying,
0107 distribution (with or without modification), making available to the
0108 public, and in some countries other activities as well.</p>
0109 
0110 <p>To &ldquo;convey&rdquo; a work means any kind of propagation that enables other
0111 parties to make or receive copies.  Mere interaction with a user through
0112 a computer network, with no transfer of a copy, is not conveying.</p>
0113 
0114 <p>An interactive user interface displays &ldquo;Appropriate Legal Notices&rdquo;
0115 to the extent that it includes a convenient and prominently visible
0116 feature that (1) displays an appropriate copyright notice, and (2)
0117 tells the user that there is no warranty for the work (except to the
0118 extent that warranties are provided), that licensees may convey the
0119 work under this License, and how to view a copy of this License.  If
0120 the interface presents a list of user commands or options, such as a
0121 menu, a prominent item in the list meets this criterion.</p>
0122 
0123 <h4><a name="section1"></a>1. Source Code.</h4>
0124 
0125 <p>The &ldquo;source code&rdquo; for a work means the preferred form of the work
0126 for making modifications to it.  &ldquo;Object code&rdquo; means any non-source
0127 form of a work.</p>
0128 
0129 <p>A &ldquo;Standard Interface&rdquo; means an interface that either is an official
0130 standard defined by a recognized standards body, or, in the case of
0131 interfaces specified for a particular programming language, one that
0132 is widely used among developers working in that language.</p>
0133 
0134 <p>The &ldquo;System Libraries&rdquo; of an executable work include anything, other
0135 than the work as a whole, that (a) is included in the normal form of
0136 packaging a Major Component, but which is not part of that Major
0137 Component, and (b) serves only to enable use of the work with that
0138 Major Component, or to implement a Standard Interface for which an
0139 implementation is available to the public in source code form.  A
0140 &ldquo;Major Component&rdquo;, in this context, means a major essential component
0141 (kernel, window system, and so on) of the specific operating system
0142 (if any) on which the executable work runs, or a compiler used to
0143 produce the work, or an object code interpreter used to run it.</p>
0144 
0145 <p>The &ldquo;Corresponding Source&rdquo; for a work in object code form means all
0146 the source code needed to generate, install, and (for an executable
0147 work) run the object code and to modify the work, including scripts to
0148 control those activities.  However, it does not include the work's
0149 System Libraries, or general-purpose tools or generally available free
0150 programs which are used unmodified in performing those activities but
0151 which are not part of the work.  For example, Corresponding Source
0152 includes interface definition files associated with source files for
0153 the work, and the source code for shared libraries and dynamically
0154 linked subprograms that the work is specifically designed to require,
0155 such as by intimate data communication or control flow between those
0156 subprograms and other parts of the work.</p>
0157 
0158 <p>The Corresponding Source need not include anything that users
0159 can regenerate automatically from other parts of the Corresponding
0160 Source.</p>
0161 
0162 <p>The Corresponding Source for a work in source code form is that
0163 same work.</p>
0164 
0165 <h4><a name="section2"></a>2. Basic Permissions.</h4>
0166 
0167 <p>All rights granted under this License are granted for the term of
0168 copyright on the Program, and are irrevocable provided the stated
0169 conditions are met.  This License explicitly affirms your unlimited
0170 permission to run the unmodified Program.  The output from running a
0171 covered work is covered by this License only if the output, given its
0172 content, constitutes a covered work.  This License acknowledges your
0173 rights of fair use or other equivalent, as provided by copyright law.</p>
0174 
0175 <p>You may make, run and propagate covered works that you do not
0176 convey, without conditions so long as your license otherwise remains
0177 in force.  You may convey covered works to others for the sole purpose
0178 of having them make modifications exclusively for you, or provide you
0179 with facilities for running those works, provided that you comply with
0180 the terms of this License in conveying all material for which you do
0181 not control copyright.  Those thus making or running the covered works
0182 for you must do so exclusively on your behalf, under your direction
0183 and control, on terms that prohibit them from making any copies of
0184 your copyrighted material outside their relationship with you.</p>
0185 
0186 <p>Conveying under any other circumstances is permitted solely under
0187 the conditions stated below.  Sublicensing is not allowed; section 10
0188 makes it unnecessary.</p>
0189 
0190 <h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4>
0191 
0192 <p>No covered work shall be deemed part of an effective technological
0193 measure under any applicable law fulfilling obligations under article
0194 11 of the WIPO copyright treaty adopted on 20 December 1996, or
0195 similar laws prohibiting or restricting circumvention of such
0196 measures.</p>
0197 
0198 <p>When you convey a covered work, you waive any legal power to forbid
0199 circumvention of technological measures to the extent such circumvention
0200 is effected by exercising rights under this License with respect to
0201 the covered work, and you disclaim any intention to limit operation or
0202 modification of the work as a means of enforcing, against the work's
0203 users, your or third parties' legal rights to forbid circumvention of
0204 technological measures.</p>
0205 
0206 <h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4>
0207 
0208 <p>You may convey verbatim copies of the Program's source code as you
0209 receive it, in any medium, provided that you conspicuously and
0210 appropriately publish on each copy an appropriate copyright notice;
0211 keep intact all notices stating that this License and any
0212 non-permissive terms added in accord with section 7 apply to the code;
0213 keep intact all notices of the absence of any warranty; and give all
0214 recipients a copy of this License along with the Program.</p>
0215 
0216 <p>You may charge any price or no price for each copy that you convey,
0217 and you may offer support or warranty protection for a fee.</p>
0218 
0219 <h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4>
0220 
0221 <p>You may convey a work based on the Program, or the modifications to
0222 produce it from the Program, in the form of source code under the
0223 terms of section 4, provided that you also meet all of these conditions:</p>
0224 
0225 <ul>
0226 <li>a) The work must carry prominent notices stating that you modified
0227     it, and giving a relevant date.</li>
0228 
0229 <li>b) The work must carry prominent notices stating that it is
0230     released under this License and any conditions added under section
0231     7.  This requirement modifies the requirement in section 4 to
0232     &ldquo;keep intact all notices&rdquo;.</li>
0233 
0234 <li>c) You must license the entire work, as a whole, under this
0235     License to anyone who comes into possession of a copy.  This
0236     License will therefore apply, along with any applicable section 7
0237     additional terms, to the whole of the work, and all its parts,
0238     regardless of how they are packaged.  This License gives no
0239     permission to license the work in any other way, but it does not
0240     invalidate such permission if you have separately received it.</li>
0241 
0242 <li>d) If the work has interactive user interfaces, each must display
0243     Appropriate Legal Notices; however, if the Program has interactive
0244     interfaces that do not display Appropriate Legal Notices, your
0245     work need not make them do so.</li>
0246 </ul>
0247 
0248 <p>A compilation of a covered work with other separate and independent
0249 works, which are not by their nature extensions of the covered work,
0250 and which are not combined with it such as to form a larger program,
0251 in or on a volume of a storage or distribution medium, is called an
0252 &ldquo;aggregate&rdquo; if the compilation and its resulting copyright are not
0253 used to limit the access or legal rights of the compilation's users
0254 beyond what the individual works permit.  Inclusion of a covered work
0255 in an aggregate does not cause this License to apply to the other
0256 parts of the aggregate.</p>
0257 
0258 <h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4>
0259 
0260 <p>You may convey a covered work in object code form under the terms
0261 of sections 4 and 5, provided that you also convey the
0262 machine-readable Corresponding Source under the terms of this License,
0263 in one of these ways:</p>
0264 
0265 <ul>
0266 <li>a) Convey the object code in, or embodied in, a physical product
0267     (including a physical distribution medium), accompanied by the
0268     Corresponding Source fixed on a durable physical medium
0269     customarily used for software interchange.</li>
0270 
0271 <li>b) Convey the object code in, or embodied in, a physical product
0272     (including a physical distribution medium), accompanied by a
0273     written offer, valid for at least three years and valid for as
0274     long as you offer spare parts or customer support for that product
0275     model, to give anyone who possesses the object code either (1) a
0276     copy of the Corresponding Source for all the software in the
0277     product that is covered by this License, on a durable physical
0278     medium customarily used for software interchange, for a price no
0279     more than your reasonable cost of physically performing this
0280     conveying of source, or (2) access to copy the
0281     Corresponding Source from a network server at no charge.</li>
0282 
0283 <li>c) Convey individual copies of the object code with a copy of the
0284     written offer to provide the Corresponding Source.  This
0285     alternative is allowed only occasionally and noncommercially, and
0286     only if you received the object code with such an offer, in accord
0287     with subsection 6b.</li>
0288 
0289 <li>d) Convey the object code by offering access from a designated
0290     place (gratis or for a charge), and offer equivalent access to the
0291     Corresponding Source in the same way through the same place at no
0292     further charge.  You need not require recipients to copy the
0293     Corresponding Source along with the object code.  If the place to
0294     copy the object code is a network server, the Corresponding Source
0295     may be on a different server (operated by you or a third party)
0296     that supports equivalent copying facilities, provided you maintain
0297     clear directions next to the object code saying where to find the
0298     Corresponding Source.  Regardless of what server hosts the
0299     Corresponding Source, you remain obligated to ensure that it is
0300     available for as long as needed to satisfy these requirements.</li>
0301 
0302 <li>e) Convey the object code using peer-to-peer transmission, provided
0303     you inform other peers where the object code and Corresponding
0304     Source of the work are being offered to the general public at no
0305     charge under subsection 6d.</li>
0306 </ul>
0307 
0308 <p>A separable portion of the object code, whose source code is excluded
0309 from the Corresponding Source as a System Library, need not be
0310 included in conveying the object code work.</p>
0311 
0312 <p>A &ldquo;User Product&rdquo; is either (1) a &ldquo;consumer product&rdquo;, which means any
0313 tangible personal property which is normally used for personal, family,
0314 or household purposes, or (2) anything designed or sold for incorporation
0315 into a dwelling.  In determining whether a product is a consumer product,
0316 doubtful cases shall be resolved in favor of coverage.  For a particular
0317 product received by a particular user, &ldquo;normally used&rdquo; refers to a
0318 typical or common use of that class of product, regardless of the status
0319 of the particular user or of the way in which the particular user
0320 actually uses, or expects or is expected to use, the product.  A product
0321 is a consumer product regardless of whether the product has substantial
0322 commercial, industrial or non-consumer uses, unless such uses represent
0323 the only significant mode of use of the product.</p>
0324 
0325 <p>&ldquo;Installation Information&rdquo; for a User Product means any methods,
0326 procedures, authorization keys, or other information required to install
0327 and execute modified versions of a covered work in that User Product from
0328 a modified version of its Corresponding Source.  The information must
0329 suffice to ensure that the continued functioning of the modified object
0330 code is in no case prevented or interfered with solely because
0331 modification has been made.</p>
0332 
0333 <p>If you convey an object code work under this section in, or with, or
0334 specifically for use in, a User Product, and the conveying occurs as
0335 part of a transaction in which the right of possession and use of the
0336 User Product is transferred to the recipient in perpetuity or for a
0337 fixed term (regardless of how the transaction is characterized), the
0338 Corresponding Source conveyed under this section must be accompanied
0339 by the Installation Information.  But this requirement does not apply
0340 if neither you nor any third party retains the ability to install
0341 modified object code on the User Product (for example, the work has
0342 been installed in ROM).</p>
0343 
0344 <p>The requirement to provide Installation Information does not include a
0345 requirement to continue to provide support service, warranty, or updates
0346 for a work that has been modified or installed by the recipient, or for
0347 the User Product in which it has been modified or installed.  Access to a
0348 network may be denied when the modification itself materially and
0349 adversely affects the operation of the network or violates the rules and
0350 protocols for communication across the network.</p>
0351 
0352 <p>Corresponding Source conveyed, and Installation Information provided,
0353 in accord with this section must be in a format that is publicly
0354 documented (and with an implementation available to the public in
0355 source code form), and must require no special password or key for
0356 unpacking, reading or copying.</p>
0357 
0358 <h4><a name="section7"></a>7. Additional Terms.</h4>
0359 
0360 <p>&ldquo;Additional permissions&rdquo; are terms that supplement the terms of this
0361 License by making exceptions from one or more of its conditions.
0362 Additional permissions that are applicable to the entire Program shall
0363 be treated as though they were included in this License, to the extent
0364 that they are valid under applicable law.  If additional permissions
0365 apply only to part of the Program, that part may be used separately
0366 under those permissions, but the entire Program remains governed by
0367 this License without regard to the additional permissions.</p>
0368 
0369 <p>When you convey a copy of a covered work, you may at your option
0370 remove any additional permissions from that copy, or from any part of
0371 it.  (Additional permissions may be written to require their own
0372 removal in certain cases when you modify the work.)  You may place
0373 additional permissions on material, added by you to a covered work,
0374 for which you have or can give appropriate copyright permission.</p>
0375 
0376 <p>Notwithstanding any other provision of this License, for material you
0377 add to a covered work, you may (if authorized by the copyright holders of
0378 that material) supplement the terms of this License with terms:</p>
0379 
0380 <ul>
0381 <li>a) Disclaiming warranty or limiting liability differently from the
0382     terms of sections 15 and 16 of this License; or</li>
0383 
0384 <li>b) Requiring preservation of specified reasonable legal notices or
0385     author attributions in that material or in the Appropriate Legal
0386     Notices displayed by works containing it; or</li>
0387 
0388 <li>c) Prohibiting misrepresentation of the origin of that material, or
0389     requiring that modified versions of such material be marked in
0390     reasonable ways as different from the original version; or</li>
0391 
0392 <li>d) Limiting the use for publicity purposes of names of licensors or
0393     authors of the material; or</li>
0394 
0395 <li>e) Declining to grant rights under trademark law for use of some
0396     trade names, trademarks, or service marks; or</li>
0397 
0398 <li>f) Requiring indemnification of licensors and authors of that
0399     material by anyone who conveys the material (or modified versions of
0400     it) with contractual assumptions of liability to the recipient, for
0401     any liability that these contractual assumptions directly impose on
0402     those licensors and authors.</li>
0403 </ul>
0404 
0405 <p>All other non-permissive additional terms are considered &ldquo;further
0406 restrictions&rdquo; within the meaning of section 10.  If the Program as you
0407 received it, or any part of it, contains a notice stating that it is
0408 governed by this License along with a term that is a further
0409 restriction, you may remove that term.  If a license document contains
0410 a further restriction but permits relicensing or conveying under this
0411 License, you may add to a covered work material governed by the terms
0412 of that license document, provided that the further restriction does
0413 not survive such relicensing or conveying.</p>
0414 
0415 <p>If you add terms to a covered work in accord with this section, you
0416 must place, in the relevant source files, a statement of the
0417 additional terms that apply to those files, or a notice indicating
0418 where to find the applicable terms.</p>
0419 
0420 <p>Additional terms, permissive or non-permissive, may be stated in the
0421 form of a separately written license, or stated as exceptions;
0422 the above requirements apply either way.</p>
0423 
0424 <h4><a name="section8"></a>8. Termination.</h4>
0425 
0426 <p>You may not propagate or modify a covered work except as expressly
0427 provided under this License.  Any attempt otherwise to propagate or
0428 modify it is void, and will automatically terminate your rights under
0429 this License (including any patent licenses granted under the third
0430 paragraph of section 11).</p>
0431 
0432 <p>However, if you cease all violation of this License, then your
0433 license from a particular copyright holder is reinstated (a)
0434 provisionally, unless and until the copyright holder explicitly and
0435 finally terminates your license, and (b) permanently, if the copyright
0436 holder fails to notify you of the violation by some reasonable means
0437 prior to 60 days after the cessation.</p>
0438 
0439 <p>Moreover, your license from a particular copyright holder is
0440 reinstated permanently if the copyright holder notifies you of the
0441 violation by some reasonable means, this is the first time you have
0442 received notice of violation of this License (for any work) from that
0443 copyright holder, and you cure the violation prior to 30 days after
0444 your receipt of the notice.</p>
0445 
0446 <p>Termination of your rights under this section does not terminate the
0447 licenses of parties who have received copies or rights from you under
0448 this License.  If your rights have been terminated and not permanently
0449 reinstated, you do not qualify to receive new licenses for the same
0450 material under section 10.</p>
0451 
0452 <h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4>
0453 
0454 <p>You are not required to accept this License in order to receive or
0455 run a copy of the Program.  Ancillary propagation of a covered work
0456 occurring solely as a consequence of using peer-to-peer transmission
0457 to receive a copy likewise does not require acceptance.  However,
0458 nothing other than this License grants you permission to propagate or
0459 modify any covered work.  These actions infringe copyright if you do
0460 not accept this License.  Therefore, by modifying or propagating a
0461 covered work, you indicate your acceptance of this License to do so.</p>
0462 
0463 <h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4>
0464 
0465 <p>Each time you convey a covered work, the recipient automatically
0466 receives a license from the original licensors, to run, modify and
0467 propagate that work, subject to this License.  You are not responsible
0468 for enforcing compliance by third parties with this License.</p>
0469 
0470 <p>An &ldquo;entity transaction&rdquo; is a transaction transferring control of an
0471 organization, or substantially all assets of one, or subdividing an
0472 organization, or merging organizations.  If propagation of a covered
0473 work results from an entity transaction, each party to that
0474 transaction who receives a copy of the work also receives whatever
0475 licenses to the work the party's predecessor in interest had or could
0476 give under the previous paragraph, plus a right to possession of the
0477 Corresponding Source of the work from the predecessor in interest, if
0478 the predecessor has it or can get it with reasonable efforts.</p>
0479 
0480 <p>You may not impose any further restrictions on the exercise of the
0481 rights granted or affirmed under this License.  For example, you may
0482 not impose a license fee, royalty, or other charge for exercise of
0483 rights granted under this License, and you may not initiate litigation
0484 (including a cross-claim or counterclaim in a lawsuit) alleging that
0485 any patent claim is infringed by making, using, selling, offering for
0486 sale, or importing the Program or any portion of it.</p>
0487 
0488 <h4><a name="section11"></a>11. Patents.</h4>
0489 
0490 <p>A &ldquo;contributor&rdquo; is a copyright holder who authorizes use under this
0491 License of the Program or a work on which the Program is based.  The
0492 work thus licensed is called the contributor's &ldquo;contributor version&rdquo;.</p>
0493 
0494 <p>A contributor's &ldquo;essential patent claims&rdquo; are all patent claims
0495 owned or controlled by the contributor, whether already acquired or
0496 hereafter acquired, that would be infringed by some manner, permitted
0497 by this License, of making, using, or selling its contributor version,
0498 but do not include claims that would be infringed only as a
0499 consequence of further modification of the contributor version.  For
0500 purposes of this definition, &ldquo;control&rdquo; includes the right to grant
0501 patent sublicenses in a manner consistent with the requirements of
0502 this License.</p>
0503 
0504 <p>Each contributor grants you a non-exclusive, worldwide, royalty-free
0505 patent license under the contributor's essential patent claims, to
0506 make, use, sell, offer for sale, import and otherwise run, modify and
0507 propagate the contents of its contributor version.</p>
0508 
0509 <p>In the following three paragraphs, a &ldquo;patent license&rdquo; is any express
0510 agreement or commitment, however denominated, not to enforce a patent
0511 (such as an express permission to practice a patent or covenant not to
0512 sue for patent infringement).  To &ldquo;grant&rdquo; such a patent license to a
0513 party means to make such an agreement or commitment not to enforce a
0514 patent against the party.</p>
0515 
0516 <p>If you convey a covered work, knowingly relying on a patent license,
0517 and the Corresponding Source of the work is not available for anyone
0518 to copy, free of charge and under the terms of this License, through a
0519 publicly available network server or other readily accessible means,
0520 then you must either (1) cause the Corresponding Source to be so
0521 available, or (2) arrange to deprive yourself of the benefit of the
0522 patent license for this particular work, or (3) arrange, in a manner
0523 consistent with the requirements of this License, to extend the patent
0524 license to downstream recipients.  &ldquo;Knowingly relying&rdquo; means you have
0525 actual knowledge that, but for the patent license, your conveying the
0526 covered work in a country, or your recipient's use of the covered work
0527 in a country, would infringe one or more identifiable patents in that
0528 country that you have reason to believe are valid.</p>
0529   
0530 <p>If, pursuant to or in connection with a single transaction or
0531 arrangement, you convey, or propagate by procuring conveyance of, a
0532 covered work, and grant a patent license to some of the parties
0533 receiving the covered work authorizing them to use, propagate, modify
0534 or convey a specific copy of the covered work, then the patent license
0535 you grant is automatically extended to all recipients of the covered
0536 work and works based on it.</p>
0537 
0538 <p>A patent license is &ldquo;discriminatory&rdquo; if it does not include within
0539 the scope of its coverage, prohibits the exercise of, or is
0540 conditioned on the non-exercise of one or more of the rights that are
0541 specifically granted under this License.  You may not convey a covered
0542 work if you are a party to an arrangement with a third party that is
0543 in the business of distributing software, under which you make payment
0544 to the third party based on the extent of your activity of conveying
0545 the work, and under which the third party grants, to any of the
0546 parties who would receive the covered work from you, a discriminatory
0547 patent license (a) in connection with copies of the covered work
0548 conveyed by you (or copies made from those copies), or (b) primarily
0549 for and in connection with specific products or compilations that
0550 contain the covered work, unless you entered into that arrangement,
0551 or that patent license was granted, prior to 28 March 2007.</p>
0552 
0553 <p>Nothing in this License shall be construed as excluding or limiting
0554 any implied license or other defenses to infringement that may
0555 otherwise be available to you under applicable patent law.</p>
0556 
0557 <h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4>
0558 
0559 <p>If conditions are imposed on you (whether by court order, agreement or
0560 otherwise) that contradict the conditions of this License, they do not
0561 excuse you from the conditions of this License.  If you cannot convey a
0562 covered work so as to satisfy simultaneously your obligations under this
0563 License and any other pertinent obligations, then as a consequence you may
0564 not convey it at all.  For example, if you agree to terms that obligate you
0565 to collect a royalty for further conveying from those to whom you convey
0566 the Program, the only way you could satisfy both those terms and this
0567 License would be to refrain entirely from conveying the Program.</p>
0568 
0569 <h4><a name="section13"></a>13. Use with the GNU Affero General Public License.</h4>
0570 
0571 <p>Notwithstanding any other provision of this License, you have
0572 permission to link or combine any covered work with a work licensed
0573 under version 3 of the GNU Affero General Public License into a single
0574 combined work, and to convey the resulting work.  The terms of this
0575 License will continue to apply to the part which is the covered work,
0576 but the special requirements of the GNU Affero General Public License,
0577 section 13, concerning interaction through a network will apply to the
0578 combination as such.</p>
0579 
0580 <h4><a name="section14"></a>14. Revised Versions of this License.</h4>
0581 
0582 <p>The Free Software Foundation may publish revised and/or new versions of
0583 the GNU General Public License from time to time.  Such new versions will
0584 be similar in spirit to the present version, but may differ in detail to
0585 address new problems or concerns.</p>
0586 
0587 <p>Each version is given a distinguishing version number.  If the
0588 Program specifies that a certain numbered version of the GNU General
0589 Public License &ldquo;or any later version&rdquo; applies to it, you have the
0590 option of following the terms and conditions either of that numbered
0591 version or of any later version published by the Free Software
0592 Foundation.  If the Program does not specify a version number of the
0593 GNU General Public License, you may choose any version ever published
0594 by the Free Software Foundation.</p>
0595 
0596 <p>If the Program specifies that a proxy can decide which future
0597 versions of the GNU General Public License can be used, that proxy's
0598 public statement of acceptance of a version permanently authorizes you
0599 to choose that version for the Program.</p>
0600 
0601 <p>Later license versions may give you additional or different
0602 permissions.  However, no additional obligations are imposed on any
0603 author or copyright holder as a result of your choosing to follow a
0604 later version.</p>
0605 
0606 <h4><a name="section15"></a>15. Disclaimer of Warranty.</h4>
0607 
0608 <p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
0609 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
0610 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM &ldquo;AS IS&rdquo; WITHOUT WARRANTY
0611 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
0612 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
0613 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
0614 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
0615 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p>
0616 
0617 <h4><a name="section16"></a>16. Limitation of Liability.</h4>
0618 
0619 <p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
0620 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
0621 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
0622 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
0623 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
0624 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
0625 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
0626 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
0627 SUCH DAMAGES.</p>
0628 
0629 <h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4>
0630 
0631 <p>If the disclaimer of warranty and limitation of liability provided
0632 above cannot be given local legal effect according to their terms,
0633 reviewing courts shall apply local law that most closely approximates
0634 an absolute waiver of all civil liability in connection with the
0635 Program, unless a warranty or assumption of liability accompanies a
0636 copy of the Program in return for a fee.</p>
0637 
0638 <p>END OF TERMS AND CONDITIONS</p>
0639 
0640 <h3><a name="howto"></a>How to Apply These Terms to Your New Programs</h3>
0641 
0642 <p>If you develop a new program, and you want it to be of the greatest
0643 possible use to the public, the best way to achieve this is to make it
0644 free software which everyone can redistribute and change under these terms.</p>
0645 
0646 <p>To do so, attach the following notices to the program.  It is safest
0647 to attach them to the start of each source file to most effectively
0648 state the exclusion of warranty; and each file should have at least
0649 the &ldquo;copyright&rdquo; line and a pointer to where the full notice is found.</p>
0650 
0651 <pre>    &lt;one line to give the program's name and a brief idea of what it does.&gt;
0652     Copyright (C) &lt;year&gt;  &lt;name of author&gt;

0654     This program is free software: you can redistribute it and/or modify
0655     it under the terms of the GNU General Public License as published by

0657     (at your option) any later version.

0660     but WITHOUT ANY WARRANTY; without even the implied warranty of
0661     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
0662     GNU General Public License for more details.
0663 
0664     You should have received a copy of the GNU General Public License
0665     along with this program.  If not, see &lt;http://www.gnu.org/licenses/&gt;.
0666 </pre>
0667 
0668 <p>Also add information on how to contact you by electronic and paper mail.</p>
0669 
0670 <p>If the program does terminal interaction, make it output a short
0671 notice like this when it starts in an interactive mode:</p>
0672 
0673 <pre>    &lt;program&gt;  Copyright (C) &lt;year&gt;  &lt;name of author&gt;
0674     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
0675     This is free software, and you are welcome to redistribute it
0676     under certain conditions; type `show c' for details.
0677 </pre>
0678 
0679 <p>The hypothetical commands `show w' and `show c' should show the appropriate
0680 parts of the General Public License.  Of course, your program's commands
0681 might be different; for a GUI interface, you would use an &ldquo;about box&rdquo;.</p>
0682 
0683 <p>You should also get your employer (if you work as a programmer) or school,
0684 if any, to sign a &ldquo;copyright disclaimer&rdquo; for the program, if necessary.

0687 
0688 <p>The GNU General Public License does not permit incorporating your program
0689 into proprietary programs.  If your program is a subroutine library, you
0690 may consider it more useful to permit linking proprietary applications with
0691 the library.  If this is what you want to do, use the GNU Lesser General
0692 Public License instead of this License.  But first, please read
