    25 
       
    26 \noindent\indent
       
    27   The GNU General Public License is a free, copyleft license for
       
    28 software and other kinds of works.
       
    29 
       
    30   The licenses for most software and other practical works are designed
       
    31 to take away your freedom to share and change the works.  By contrast,
       
    32 the GNU General Public License is intended to guarantee your freedom to
       
    33 share and change all versions of a program--to make sure it remains free
       
    34 software for all its users.  We, the Free Software Foundation, use the
       
    35 GNU General Public License for most of our software; it applies also to
       
    36 any other work released this way by its authors.  You can apply it to
       
    37 your programs, too.
       
    38 
       
    39   When we speak of free software, we are referring to freedom, not
       
    40 price.  Our General Public Licenses are designed to make sure that you
       
    41 have the freedom to distribute copies of free software (and charge for
       
    42 them if you wish), that you receive source code or can get it if you
       
    43 want it, that you can change the software or use pieces of it in new
       
    44 free programs, and that you know you can do these things.
       
    45 
       
    46   To protect your rights, we need to prevent others from denying you
       
    47 these rights or asking you to surrender the rights.  Therefore, you have
       
    48 certain responsibilities if you distribute copies of the software, or if
       
    49 you modify it: responsibilities to respect the freedom of others.
       
    50 
       
    51   For example, if you distribute copies of such a program, whether
       
    52 gratis or for a fee, you must pass on to the recipients the same
       
    53 freedoms that you received.  You must make sure that they, too, receive
       
    54 or can get the source code.  And you must show them these terms so they
       
    55 know their rights.
       
    56 
       
    57   Developers that use the GNU GPL protect your rights with two steps:
       
    58 (1) assert copyright on the software, and (2) offer you this License
       
    59 giving you legal permission to copy, distribute and/or modify it.
       
    60 
       
    61   For the developers' and authors' protection, the GPL clearly explains
       
    62 that there is no warranty for this free software.  For both users' and
       
    63 authors' sake, the GPL requires that modified versions be marked as
       
    64 changed, so that their problems will not be attributed erroneously to
       
    65 authors of previous versions.
       
    66 
       
    67   Some devices are designed to deny users access to install or run
       
    68 modified versions of the software inside them, although the manufacturer
       
    69 can do so.  This is fundamentally incompatible with the aim of
       
    70 protecting users' freedom to change the software.  The systematic
       
    71 pattern of such abuse occurs in the area of products for individuals to
       
    72 use, which is precisely where it is most unacceptable.  Therefore, we
       
    73 have designed this version of the GPL to prohibit the practice for those
       
    74 products.  If such problems arise substantially in other domains, we
       
    75 stand ready to extend this provision to those domains in future versions
       
    76 of the GPL, as needed to protect the freedom of users.
       
    77 
       
    78   Finally, every program is threatened constantly by software patents.
       
    79 States should not allow patents to restrict development and use of
       
    80 software on general-purpose computers, but in those that do, we wish to
       
    81 avoid the special danger that patents applied to a free program could
       
    82 make it effectively proprietary.  To prevent this, the GPL assures that
       
    83 patents cannot be used to render the program non-free.
       
    84 
       
    85   The precise terms and conditions for copying, distribution and
       
    86 modification follow.

    89 
       
    90 \subsubsection*{0. Definitions.}
       
    91 
       
    92 \noindent\indent
       
    93   ``This License'' refers to version 3 of the GNU General Public
       
    94 License.
       
    95 
       
    96   ``Copyright'' also means copyright-like laws that apply to other kinds
       
    97 of works, such as semiconductor masks.
       
    98 
       
    99   ``The Program'' refers to any copyrightable work licensed under this
       
   100 License.  Each licensee is addressed as ``you''.  ``Licensees'' and
       
   101 ``recipients'' may be individuals or organizations.
       
   102 
       
   103   To ``modify'' a work means to copy from or adapt all or part of the
       
   104 work in a fashion requiring copyright permission, other than the making
       
   105 of an exact copy.  The resulting work is called a ``modified version''
       
   106 of the earlier work or a work ``based on'' the earlier work.
       
   107 
       
   108   A ``covered work'' means either the unmodified Program or a work based
       
   109 on the Program.
       
   110 
       
   111   To ``propagate'' a work means to do anything with it that, without
       
   112 permission, would make you directly or secondarily liable for
       
   113 infringement under applicable copyright law, except executing it on a
       
   114 computer or modifying a private copy.  Propagation includes copying,
       
   115 distribution (with or without modification), making available to the
       
   116 public, and in some countries other activities as well.
       
   117 
       
   118   To ``convey'' a work means any kind of propagation that enables other
       
   119 parties to make or receive copies.  Mere interaction with a user through
       
   120 a computer network, with no transfer of a copy, is not conveying.
       
   121 
       
   122   An interactive user interface displays ``Appropriate Legal Notices''
       
   123 to the extent that it includes a convenient and prominently visible
       
   124 feature that (1) displays an appropriate copyright notice, and (2)
       
   125 tells the user that there is no warranty for the work (except to the
       
   126 extent that warranties are provided), that licensees may convey the
       
   127 work under this License, and how to view a copy of this License.  If
       
   128 the interface presents a list of user commands or options, such as a
       
   129 menu, a prominent item in the list meets this criterion.
       
   130 
       
   131 \subsubsection*{1. Source Code.}
       
   132 
       
   133 \noindent\indent
       
   134   The ``source code'' for a work means the preferred form of the work
       
   135 for making modifications to it.  ``Object code'' means any non-source
       
   136 form of a work.
       
   137 
       
   138   A ``Standard Interface'' means an interface that either is an official
       
   139 standard defined by a recognized standards body, or, in the case of
       
   140 interfaces specified for a particular programming language, one that
       
   141 is widely used among developers working in that language.
       
   142 
       
   143   The ``System Libraries'' of an executable work include anything, other
       
   144 than the work as a whole, that (a) is included in the normal form of
       
   145 packaging a Major Component, but which is not part of that Major
       
   146 Component, and (b) serves only to enable use of the work with that
       
   147 Major Component, or to implement a Standard Interface for which an
       
   148 implementation is available to the public in source code form.  A
       
   149 ``Major Component'', in this context, means a major essential component
       
   150 (kernel, window system, and so on) of the specific operating system
       
   151 (if any) on which the executable work runs, or a compiler used to
       
   152 produce the work, or an object code interpreter used to run it.
       
   153 
       
   154   The ``Corresponding Source'' for a work in object code form means all
       
   155 the source code needed to generate, install, and (for an executable
       
   156 work) run the object code and to modify the work, including scripts to
       
   157 control those activities.  However, it does not include the work's
       
   158 System Libraries, or general-purpose tools or generally available free
       
   159 programs which are used unmodified in performing those activities but
       
   160 which are not part of the work.  For example, Corresponding Source
       
   161 includes interface definition files associated with source files for
       
   162 the work, and the source code for shared libraries and dynamically
       
   163 linked subprograms that the work is specifically designed to require,
       
   164 such as by intimate data communication or control flow between those
       
   165 subprograms and other parts of the work.
       
   166 
       
   167   The Corresponding Source need not include anything that users
       
   168 can regenerate automatically from other parts of the Corresponding
       
   169 Source.
       
   170 
       
   171   The Corresponding Source for a work in source code form is that
       
   172 same work.
       
   173 
       
   174 \subsubsection*{2. Basic Permissions.}
       
   175 
       
   176 \noindent\indent
       
   177   All rights granted under this License are granted for the term of
       
   178 copyright on the Program, and are irrevocable provided the stated
       
   179 conditions are met.  This License explicitly affirms your unlimited
       
   180 permission to run the unmodified Program.  The output from running a
       
   181 covered work is covered by this License only if the output, given its
       
   182 content, constitutes a covered work.  This License acknowledges your
       
   183 rights of fair use or other equivalent, as provided by copyright law.
       
   184 
       
   185   You may make, run and propagate covered works that you do not
       
   186 convey, without conditions so long as your license otherwise remains
       
   187 in force.  You may convey covered works to others for the sole purpose
       
   188 of having them make modifications exclusively for you, or provide you
       
   189 with facilities for running those works, provided that you comply with
       
   190 the terms of this License in conveying all material for which you do
       
   191 not control copyright.  Those thus making or running the covered works
       
   192 for you must do so exclusively on your behalf, under your direction
       
   193 and control, on terms that prohibit them from making any copies of
       
   194 your copyrighted material outside their relationship with you.
       
   195 
       
   196   Conveying under any other circumstances is permitted solely under
       
   197 the conditions stated below.  Sublicensing is not allowed; section 10
       
   198 makes it unnecessary.
       
   199 
       
   200 \subsubsection*{3. Protecting Users' Legal Rights From
       
   201 Anti-Circumvention Law.}
       
   202 
       
   203 \noindent\indent
       
   204   No covered work shall be deemed part of an effective technological
       
   205 measure under any applicable law fulfilling obligations under article
       
   206 11 of the WIPO copyright treaty adopted on 20 December 1996, or
       
   207 similar laws prohibiting or restricting circumvention of such
       
   208 measures.
       
   209 
       
   210   When you convey a covered work, you waive any legal power to forbid
       
   211 circumvention of technological measures to the extent such circumvention
       
   212 is effected by exercising rights under this License with respect to
       
   213 the covered work, and you disclaim any intention to limit operation or
       
   214 modification of the work as a means of enforcing, against the work's
       
   215 users, your or third parties' legal rights to forbid circumvention of
       
   216 technological measures.
       
   217 
       
   218 \subsubsection*{4. Conveying Verbatim Copies.}
       
   219 
       
   220 \noindent\indent
       
   221   You may convey verbatim copies of the Program's source code as you
       
   222 receive it, in any medium, provided that you conspicuously and
       
   223 appropriately publish on each copy an appropriate copyright notice;
       
   224 keep intact all notices stating that this License and any
       
   225 non-permissive terms added in accord with section 7 apply to the code;
       
   226 keep intact all notices of the absence of any warranty; and give all
       
   227 recipients a copy of this License along with the Program.
       
   228 
       
   229   You may charge any price or no price for each copy that you convey,
       
   230 and you may offer support or warranty protection for a fee.
       
   231 
       
   232 \subsubsection*{5. Conveying Modified Source Versions.}
       
   233 
       
   234   You may convey a work based on the Program, or the modifications to
       
   235 produce it from the Program, in the form of source code under the
       
   236 terms of section 4, provided that you also meet all of these conditions:
       
   237 
       
   238     a) The work must carry prominent notices stating that you modified
       
   239     it, and giving a relevant date.
       
   240 
       
   241     b) The work must carry prominent notices stating that it is
       
   242     released under this License and any conditions added under section
       
   243     7.  This requirement modifies the requirement in section 4 to
       
   244     ``keep intact all notices''.
       
   245 
       
   246     c) You must license the entire work, as a whole, under this
       
   247     License to anyone who comes into possession of a copy.  This
       
   248     License will therefore apply, along with any applicable section 7
       
   249     additional terms, to the whole of the work, and all its parts,
       
   250     regardless of how they are packaged.  This License gives no
       
   251     permission to license the work in any other way, but it does not
       
   252     invalidate such permission if you have separately received it.
       
   253 
       
   254     d) If the work has interactive user interfaces, each must display
       
   255     Appropriate Legal Notices; however, if the Program has interactive
       
   256     interfaces that do not display Appropriate Legal Notices, your
       
   257     work need not make them do so.
       
   258 
       
   259   A compilation of a covered work with other separate and independent
       
   260 works, which are not by their nature extensions of the covered work,
       
   261 and which are not combined with it such as to form a larger program,
       
   262 in or on a volume of a storage or distribution medium, is called an
       
   263 ``aggregate'' if the compilation and its resulting copyright are not
       
   264 used to limit the access or legal rights of the compilation's users
       
   265 beyond what the individual works permit.  Inclusion of a covered work
       
   266 in an aggregate does not cause this License to apply to the other
       
   267 parts of the aggregate.
       
   268 
       
   269 \subsubsection*{6. Conveying Non-Source Forms.}
       
   270 
       
   271   You may convey a covered work in object code form under the terms
       
   272 of sections 4 and 5, provided that you also convey the
       
   273 machine-readable Corresponding Source under the terms of this License,
       
   274 in one of these ways:
       
   275 
       
   276     a) Convey the object code in, or embodied in, a physical product
       
   277     (including a physical distribution medium), accompanied by the
       
   278     Corresponding Source fixed on a durable physical medium
       
   279     customarily used for software interchange.
       
   280 
       
   281     b) Convey the object code in, or embodied in, a physical product
       
   282     (including a physical distribution medium), accompanied by a
       
   283     written offer, valid for at least three years and valid for as
       
   284     long as you offer spare parts or customer support for that product
       
   285     model, to give anyone who possesses the object code either (1) a
       
   286     copy of the Corresponding Source for all the software in the
       
   287     product that is covered by this License, on a durable physical
       
   288     medium customarily used for software interchange, for a price no
       
   289     more than your reasonable cost of physically performing this
       
   290     conveying of source, or (2) access to copy the
       
   291     Corresponding Source from a network server at no charge.
       
   292 
       
   293     c) Convey individual copies of the object code with a copy of the
       
   294     written offer to provide the Corresponding Source.  This
       
   295     alternative is allowed only occasionally and noncommercially, and
       
   296     only if you received the object code with such an offer, in accord
       
   297     with subsection 6b.
       
   298 
       
   299     d) Convey the object code by offering access from a designated
       
   300     place (gratis or for a charge), and offer equivalent access to the
       
   301     Corresponding Source in the same way through the same place at no
       
   302     further charge.  You need not require recipients to copy the
       
   303     Corresponding Source along with the object code.  If the place to
       
   304     copy the object code is a network server, the Corresponding Source
       
   305     may be on a different server (operated by you or a third party)
       
   306     that supports equivalent copying facilities, provided you maintain
       
   307     clear directions next to the object code saying where to find the
       
   308     Corresponding Source.  Regardless of what server hosts the
       
   309     Corresponding Source, you remain obligated to ensure that it is
       
   310     available for as long as needed to satisfy these requirements.
       
   311 
       
   312     e) Convey the object code using peer-to-peer transmission, provided
       
   313     you inform other peers where the object code and Corresponding
       
   314     Source of the work are being offered to the general public at no
       
   315     charge under subsection 6d.
       
   316 
       
   317   A separable portion of the object code, whose source code is excluded
       
   318 from the Corresponding Source as a System Library, need not be
       
   319 included in conveying the object code work.
       
   320 
       
   321   A ``User Product'' is either (1) a ``consumer product'', which means
       
   322 any tangible personal property which is normally used for personal,
       
   323 family, or household purposes, or (2) anything designed or sold for
       
   324 incorporation into a dwelling.  In determining whether a product is a
       
   325 consumer product, doubtful cases shall be resolved in favor of coverage.
       
   326 For a particular product received by a particular user, ``normally
       
   327 used'' refers to a typical or common use of that class of product,
       
   328 regardless of the status of the particular user or of the way in which
       
   329 the particular user actually uses, or expects or is expected to use, the
       
   330 product.  A product is a consumer product regardless of whether the
       
   331 product has substantial commercial, industrial or non-consumer uses,
       
   332 unless such uses represent the only significant mode of use of the
       
   333 product.
       
   334 
       
   335   ``Installation Information'' for a User Product means any methods,
       
   336 procedures, authorization keys, or other information required to install
       
   337 and execute modified versions of a covered work in that User Product
       
   338 from a modified version of its Corresponding Source.  The information
       
   339 must suffice to ensure that the continued functioning of the modified
       
   340 object code is in no case prevented or interfered with solely because
       
   341 modification has been made.
       
   342 
       
   343   If you convey an object code work under this section in, or with, or
       
   344 specifically for use in, a User Product, and the conveying occurs as
       
   345 part of a transaction in which the right of possession and use of the
       
   346 User Product is transferred to the recipient in perpetuity or for a
       
   347 fixed term (regardless of how the transaction is characterized), the
       
   348 Corresponding Source conveyed under this section must be accompanied
       
   349 by the Installation Information.  But this requirement does not apply
       
   350 if neither you nor any third party retains the ability to install
       
   351 modified object code on the User Product (for example, the work has
       
   352 been installed in ROM).
       
   353 
       
   354   The requirement to provide Installation Information does not include a
       
   355 requirement to continue to provide support service, warranty, or updates
       
   356 for a work that has been modified or installed by the recipient, or for
       
   357 the User Product in which it has been modified or installed.  Access to
       
   358 a network may be denied when the modification itself materially and
       
   359 adversely affects the operation of the network or violates the rules and
       
   360 protocols for communication across the network.
       
   361 
       
   362   Corresponding Source conveyed, and Installation Information provided,
       
   363 in accord with this section must be in a format that is publicly
       
   364 documented (and with an implementation available to the public in
       
   365 source code form), and must require no special password or key for
       
   366 unpacking, reading or copying.
       
   367 
       
   368 \subsubsection*{7. Additional Terms.}
       
   369 
       
   370 \noindent\indent
       
   371   ``Additional permissions'' are terms that supplement the terms of this
       
   372 License by making exceptions from one or more of its conditions.
       
   373 Additional permissions that are applicable to the entire Program shall
       
   374 be treated as though they were included in this License, to the extent
       
   375 that they are valid under applicable law.  If additional permissions
       
   376 apply only to part of the Program, that part may be used separately
       
   377 under those permissions, but the entire Program remains governed by
       
   378 this License without regard to the additional permissions.
       
   379 
       
   380   When you convey a copy of a covered work, you may at your option
       
   381 remove any additional permissions from that copy, or from any part of
       
   382 it.  (Additional permissions may be written to require their own
       
   383 removal in certain cases when you modify the work.)  You may place
       
   384 additional permissions on material, added by you to a covered work,
       
   385 for which you have or can give appropriate copyright permission.
       
   386 
       
   387   Notwithstanding any other provision of this License, for material you
       
   388 add to a covered work, you may (if authorized by the copyright holders
       
   389 of that material) supplement the terms of this License with terms:
       
   390 
       
   391     a) Disclaiming warranty or limiting liability differently from the
       
   392     terms of sections 15 and 16 of this License; or
       
   393 
       
   394     b) Requiring preservation of specified reasonable legal notices or
       
   395     author attributions in that material or in the Appropriate Legal
       
   396     Notices displayed by works containing it; or
       
   397 
       
   398     c) Prohibiting misrepresentation of the origin of that material, or
       
   399     requiring that modified versions of such material be marked in
       
   400     reasonable ways as different from the original version; or
       
   401 
       
   402     d) Limiting the use for publicity purposes of names of licensors or
       
   403     authors of the material; or
       
   404 
       
   405     e) Declining to grant rights under trademark law for use of some
       
   406     trade names, trademarks, or service marks; or
       
   407 
       
   408     f) Requiring indemnification of licensors and authors of that
       
   409     material by anyone who conveys the material (or modified versions of
       
   410     it) with contractual assumptions of liability to the recipient, for
       
   411     any liability that these contractual assumptions directly impose on
       
   412     those licensors and authors.
       
   413 
       
   414   All other non-permissive additional terms are considered ``further
       
   415 restrictions'' within the meaning of section 10.  If the Program as you
       
   416 received it, or any part of it, contains a notice stating that it is
       
   417 governed by this License along with a term that is a further
       
   418 restriction, you may remove that term.  If a license document contains
       
   419 a further restriction but permits relicensing or conveying under this
       
   420 License, you may add to a covered work material governed by the terms
       
   421 of that license document, provided that the further restriction does
       
   422 not survive such relicensing or conveying.
       
   423 
       
   424   If you add terms to a covered work in accord with this section, you
       
   425 must place, in the relevant source files, a statement of the
       
   426 additional terms that apply to those files, or a notice indicating
       
   427 where to find the applicable terms.
       
   428 
       
   429   Additional terms, permissive or non-permissive, may be stated in the
       
   430 form of a separately written license, or stated as exceptions;
       
   431 the above requirements apply either way.
       
   432 
       
   433 \subsubsection*{8. Termination.}
       
   434 
       
   435 \noindent\indent
       
   436   You may not propagate or modify a covered work except as expressly
       
   437 provided under this License.  Any attempt otherwise to propagate or
       
   438 modify it is void, and will automatically terminate your rights under
       
   439 this License (including any patent licenses granted under the third
       
   440 paragraph of section 11).
       
   441 
       
   442   However, if you cease all violation of this License, then your
       
   443 license from a particular copyright holder is reinstated (a)
       
   444 provisionally, unless and until the copyright holder explicitly and
       
   445 finally terminates your license, and (b) permanently, if the copyright
       
   446 holder fails to notify you of the violation by some reasonable means
       
   447 prior to 60 days after the cessation.
       
   448 
       
   449   Moreover, your license from a particular copyright holder is
       
   450 reinstated permanently if the copyright holder notifies you of the
       
   451 violation by some reasonable means, this is the first time you have
       
   452 received notice of violation of this License (for any work) from that
       
   453 copyright holder, and you cure the violation prior to 30 days after
       
   454 your receipt of the notice.
       
   455 
       
   456   Termination of your rights under this section does not terminate the
       
   457 licenses of parties who have received copies or rights from you under
       
   458 this License.  If your rights have been terminated and not permanently
       
   459 reinstated, you do not qualify to receive new licenses for the same
       
   460 material under section 10.
       
   461 
       
   462 \subsubsection*{9. Acceptance Not Required for Having Copies.}
       
   463 
       
   464 \noindent\indent
       
   465   You are not required to accept this License in order to receive or
       
   466 run a copy of the Program.  Ancillary propagation of a covered work
       
   467 occurring solely as a consequence of using peer-to-peer transmission
       
   468 to receive a copy likewise does not require acceptance.  However,
       
   469 nothing other than this License grants you permission to propagate or
       
   470 modify any covered work.  These actions infringe copyright if you do
       
   471 not accept this License.  Therefore, by modifying or propagating a
       
   472 covered work, you indicate your acceptance of this License to do so.
       
   473 
       
   474 \subsubsection*{10. Automatic Licensing of Downstream Recipients.}
       
   475 
       
   476 \noindent\indent
       
   477   Each time you convey a covered work, the recipient automatically
       
   478 receives a license from the original licensors, to run, modify and
       
   479 propagate that work, subject to this License.  You are not responsible
       
   480 for enforcing compliance by third parties with this License.
       
   481 
       
   482   An ``entity transaction'' is a transaction transferring control of an
       
   483 organization, or substantially all assets of one, or subdividing an
       
   484 organization, or merging organizations.  If propagation of a covered
       
   485 work results from an entity transaction, each party to that
       
   486 transaction who receives a copy of the work also receives whatever
       
   487 licenses to the work the party's predecessor in interest had or could
       
   488 give under the previous paragraph, plus a right to possession of the
       
   489 Corresponding Source of the work from the predecessor in interest, if
       
   490 the predecessor has it or can get it with reasonable efforts.
       
   491 
       
   492   You may not impose any further restrictions on the exercise of the
       
   493 rights granted or affirmed under this License.  For example, you may
       
   494 not impose a license fee, royalty, or other charge for exercise of
       
   495 rights granted under this License, and you may not initiate litigation
       
   496 (including a cross-claim or counterclaim in a lawsuit) alleging that
       
   497 any patent claim is infringed by making, using, selling, offering for
       
   498 sale, or importing the Program or any portion of it.
       
   499 
       
   500 \subsubsection*{11. Patents.}
       
   501 
       
   502 \noindent\indent
       
   503   A ``contributor'' is a copyright holder who authorizes use under this
       
   504 License of the Program or a work on which the Program is based.  The
       
   505 work thus licensed is called the contributor's ``contributor version''.
       
   506 
       
   507   A contributor's ``essential patent claims'' are all patent claims
       
   508 owned or controlled by the contributor, whether already acquired or
       
   509 hereafter acquired, that would be infringed by some manner, permitted
       
   510 by this License, of making, using, or selling its contributor version,
       
   511 but do not include claims that would be infringed only as a
       
   512 consequence of further modification of the contributor version.  For
       
   513 purposes of this definition, ``control'' includes the right to grant
       
   514 patent sublicenses in a manner consistent with the requirements of
       
   515 this License.
       
   516 
       
   517   Each contributor grants you a non-exclusive, worldwide, royalty-free
       
   518 patent license under the contributor's essential patent claims, to
       
   519 make, use, sell, offer for sale, import and otherwise run, modify and
       
   520 propagate the contents of its contributor version.
       
   521 
       
   522   In the following three paragraphs, a ``patent license'' is any express
       
   523 agreement or commitment, however denominated, not to enforce a patent
       
   524 (such as an express permission to practice a patent or covenant not to
       
   525 sue for patent infringement).  To ``grant'' such a patent license to a
       
   526 party means to make such an agreement or commitment not to enforce a
       
   527 patent against the party.
       
   528 
       
   529   If you convey a covered work, knowingly relying on a patent license,
       
   530 and the Corresponding Source of the work is not available for anyone
       
   531 to copy, free of charge and under the terms of this License, through a
       
   532 publicly available network server or other readily accessible means,
       
   533 then you must either (1) cause the Corresponding Source to be so
       
   534 available, or (2) arrange to deprive yourself of the benefit of the
       
   535 patent license for this particular work, or (3) arrange, in a manner
       
   536 consistent with the requirements of this License, to extend the patent
       
   537 license to downstream recipients.  ``Knowingly relying'' means you have
       
   538 actual knowledge that, but for the patent license, your conveying the
       
   539 covered work in a country, or your recipient's use of the covered work
       
   540 in a country, would infringe one or more identifiable patents in that
       
   541 country that you have reason to believe are valid.
       
   542 
       
   543   If, pursuant to or in connection with a single transaction or
       
   544 arrangement, you convey, or propagate by procuring conveyance of, a
       
   545 covered work, and grant a patent license to some of the parties
       
   546 receiving the covered work authorizing them to use, propagate, modify
       
   547 or convey a specific copy of the covered work, then the patent license
       
   548 you grant is automatically extended to all recipients of the covered
       
   549 work and works based on it.
       
   550 
       
   551   A patent license is ``discriminatory'' if it does not include within
       
   552 the scope of its coverage, prohibits the exercise of, or is
       
   553 conditioned on the non-exercise of one or more of the rights that are
       
   554 specifically granted under this License.  You may not convey a covered
       
   555 work if you are a party to an arrangement with a third party that is
       
   556 in the business of distributing software, under which you make payment
       
   557 to the third party based on the extent of your activity of conveying
       
   558 the work, and under which the third party grants, to any of the
       
   559 parties who would receive the covered work from you, a discriminatory
       
   560 patent license (a) in connection with copies of the covered work
       
   561 conveyed by you (or copies made from those copies), or (b) primarily
       
   562 for and in connection with specific products or compilations that
       
   563 contain the covered work, unless you entered into that arrangement,
       
   564 or that patent license was granted, prior to 28 March 2007.
       
   565 
       
   566   Nothing in this License shall be construed as excluding or limiting
       
   567 any implied license or other defenses to infringement that may
       
   568 otherwise be available to you under applicable patent law.
       
   569 
       
   570 \subsubsection*{12. No Surrender of Others' Freedom.}
       
   571 
       
   572 \noindent\indent
       
   573   If conditions are imposed on you (whether by court order, agreement or
       
   574 otherwise) that contradict the conditions of this License, they do not
       
   575 excuse you from the conditions of this License.  If you cannot convey a
       
   576 covered work so as to satisfy simultaneously your obligations under this
       
   577 License and any other pertinent obligations, then as a consequence you
       
   578 may not convey it at all.  For example, if you agree to terms that
       
   579 obligate you to collect a royalty for further conveying from those to
       
   580 whom you convey the Program, the only way you could satisfy both those
       
   581 terms and this License would be to refrain entirely from conveying the
       
   582 Program.
       
   583 
       
   584 \subsubsection*{13. Use with the GNU Affero General Public License.}
       
   585 
       
   586 \noindent\indent
       
   587   Notwithstanding any other provision of this License, you have
       
   588 permission to link or combine any covered work with a work licensed
       
   589 under version 3 of the GNU Affero General Public License into a single
       
   590 combined work, and to convey the resulting work.  The terms of this
       
   591 License will continue to apply to the part which is the covered work,
       
   592 but the special requirements of the GNU Affero General Public License,
       
   593 section 13, concerning interaction through a network will apply to the
       
   594 combination as such.
       
   595 
       
   596 \subsubsection*{14. Revised Versions of this License.}
       
   597 
       
   598 \noindent\indent
       
   599   The Free Software Foundation may publish revised and/or new versions
       
   600 of the GNU General Public License from time to time.  Such new versions
       
   601 will be similar in spirit to the present version, but may differ in
       
   602 detail to address new problems or concerns.
       
   603 
       
   604   Each version is given a distinguishing version number.  If the
       
   605 Program specifies that a certain numbered version of the GNU General
       
   606 Public License ``or any later version'' applies to it, you have the
       
   607 option of following the terms and conditions either of that numbered
       
   608 version or of any later version published by the Free Software

   610 GNU General Public License, you may choose any version ever published
       
   611 by the Free Software Foundation.
       
   612 
       
   613   If the Program specifies that a proxy can decide which future
       
   614 versions of the GNU General Public License can be used, that proxy's
       
   615 public statement of acceptance of a version permanently authorizes you
       
   616 to choose that version for the Program.
       
   617 
       
   618   Later license versions may give you additional or different
       
   619 permissions.  However, no additional obligations are imposed on any
       
   620 author or copyright holder as a result of your choosing to follow a
       
   621 later version.

   653 reviewing courts shall apply local law that most closely approximates

   662 \section*{How to Apply These Terms to Your New Programs}
       
   663 
       
   664 \noindent\indent
       
   665   If you develop a new program, and you want it to be of the greatest
       
   666 possible use to the public, the best way to achieve this is to make it
       
   667 free software which everyone can redistribute and change under these
       
   668 terms.
       
   669 
       
   670   To do so, attach the following notices to the program.  It is safest
       
   671 to attach them to the start of each source file to most effectively
       
   672 state the exclusion of warranty; and each file should have at least
       
   673 the ``copyright'' line and a pointer to where the full notice is found.
       
   674 
       
   675 \begin{verbatim}
       
   676 <one line to give the program's name and a brief idea of what it does.>
       
   677 Copyright (C) <year>  <name of author>
       
   678 
       
   679 This program is free software: you can redistribute it and/or modify
       
   680 it under the terms of the GNU General Public License as published by
       
   681 the Free Software Foundation, either version 3 of the License, or
       
   682 (at your option) any later version.
       
   683 
       
   684 This program is distributed in the hope that it will be useful,
       
   685 but WITHOUT ANY WARRANTY; without even the implied warranty of
       
   686 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the

   688 
       
   689 You should have received a copy of the GNU General Public License
       
   690 along with this program.  If not, see <http://www.gnu.org/licenses/>.
       
   691 \end{verbatim}
       
   692 
       
   693 \noindent
       
   694 Also add information on how to contact you by electronic and paper mail.
       
   695 
       
   696   If the program does terminal interaction, make it output a short
       
   697 notice like this when it starts in an interactive mode:
       
   698 
       
   699 \begin{verbatim}
       
   700 <program>  Copyright (C) <year>  <name of author>
       
   701 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
       
   702 This is free software, and you are welcome to redistribute it
       
   703 under certain conditions; type `show c' for details.
       
   704 \end{verbatim}
       
   705 
       
   706 \noindent
       
   707 The hypothetical commands `show w' and `show c' should show the
       
   708 appropriate parts of the General Public License.  Of course, your
       
   709 program's commands might be different; for a GUI interface, you would
       
   710 use an ``about box''.
       
   711 
       
   712   You should also get your employer (if you work as a programmer) or
       
   713 school, if any, to sign a ``copyright disclaimer'' for the program, if
       
   714 necessary. For more information on this, and how to apply and follow the
       
   715 GNU GPL, see \verb|<http://www.gnu.org/licenses/>|.
       
   716 
       
   717   The GNU General Public License does not permit incorporating your
       
   718 program into proprietary programs.  If your program is a subroutine
       
   719 library, you may consider it more useful to permit linking proprietary
       
   720 applications with the library.  If this is what you want to do, use the
       
   721 GNU Lesser General Public License instead of this License.  But first,
       
   722 please read \verb|<http://www.gnu.org/philosophy/why-not-lgpl.html>|.
