     1 For the avoidance of doubt, except that if any license choice other than
       
     2 GPL or LGPL is available it will apply instead, Oracle elects to use
       
     3 only the General Public License version 3 (GPLv3) at this time for any
       
     4 software where a choice of GPL license versions is made available with
       
     5 the language indicating that GPLv3 or any later version may be used.

     8 		    GNU GENERAL PUBLIC LICENSE
       
     9 		       Version 3, 29 June 2007
       
    10 
       
    11  Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
       
    12  Everyone is permitted to copy and distribute verbatim copies
       
    13  of this license document, but changing it is not allowed.
       
    14 
       
    15 			    Preamble
       
    16 
       
    17   The GNU General Public License is a free, copyleft license for
       
    18 software and other kinds of works.
       
    19 
       
    20   The licenses for most software and other practical works are designed
       
    21 to take away your freedom to share and change the works.  By contrast,
       
    22 the GNU General Public License is intended to guarantee your freedom to
       
    23 share and change all versions of a program--to make sure it remains free
       
    24 software for all its users.  We, the Free Software Foundation, use the
       
    25 GNU General Public License for most of our software; it applies also to
       
    26 any other work released this way by its authors.  You can apply it to
       
    27 your programs, too.
       
    28 
       
    29   When we speak of free software, we are referring to freedom, not
       
    30 price.  Our General Public Licenses are designed to make sure that you
       
    31 have the freedom to distribute copies of free software (and charge for
       
    32 them if you wish), that you receive source code or can get it if you
       
    33 want it, that you can change the software or use pieces of it in new
       
    34 free programs, and that you know you can do these things.
       
    35 
       
    36   To protect your rights, we need to prevent others from denying you
       
    37 these rights or asking you to surrender the rights.  Therefore, you have
       
    38 certain responsibilities if you distribute copies of the software, or if
       
    39 you modify it: responsibilities to respect the freedom of others.
       
    40 
       
    41   For example, if you distribute copies of such a program, whether
       
    42 gratis or for a fee, you must pass on to the recipients the same
       
    43 freedoms that you received.  You must make sure that they, too, receive
       
    44 or can get the source code.  And you must show them these terms so they
       
    45 know their rights.
       
    46 
       
    47   Developers that use the GNU GPL protect your rights with two steps:
       
    48 (1) assert copyright on the software, and (2) offer you this License
       
    49 giving you legal permission to copy, distribute and/or modify it.
       
    50 
       
    51   For the developers' and authors' protection, the GPL clearly explains
       
    52 that there is no warranty for this free software.  For both users' and
       
    53 authors' sake, the GPL requires that modified versions be marked as
       
    54 changed, so that their problems will not be attributed erroneously to
       
    55 authors of previous versions.
       
    56 
       
    57   Some devices are designed to deny users access to install or run
       
    58 modified versions of the software inside them, although the manufacturer
       
    59 can do so.  This is fundamentally incompatible with the aim of
       
    60 protecting users' freedom to change the software.  The systematic
       
    61 pattern of such abuse occurs in the area of products for individuals to
       
    62 use, which is precisely where it is most unacceptable.  Therefore, we
       
    63 have designed this version of the GPL to prohibit the practice for those
       
    64 products.  If such problems arise substantially in other domains, we
       
    65 stand ready to extend this provision to those domains in future versions
       
    66 of the GPL, as needed to protect the freedom of users.
       
    67 
       
    68   Finally, every program is threatened constantly by software patents.
       
    69 States should not allow patents to restrict development and use of
       
    70 software on general-purpose computers, but in those that do, we wish to
       
    71 avoid the special danger that patents applied to a free program could
       
    72 make it effectively proprietary.  To prevent this, the GPL assures that
       
    73 patents cannot be used to render the program non-free.
       
    74 
       
    75   The precise terms and conditions for copying, distribution and
       
    76 modification follow.
       
    77 
       
    78 		       TERMS AND CONDITIONS
       
    79 
       
    80   0. Definitions.
       
    81 
       
    82   "This License" refers to version 3 of the GNU General Public License.
       
    83 
       
    84   "Copyright" also means copyright-like laws that apply to other kinds of
       
    85 works, such as semiconductor masks.
       
    86  
       
    87   "The Program" refers to any copyrightable work licensed under this
       
    88 License.  Each licensee is addressed as "you".  "Licensees" and
       
    89 "recipients" may be individuals or organizations.
       
    90 
       
    91   To "modify" a work means to copy from or adapt all or part of the work
       
    92 in a fashion requiring copyright permission, other than the making of an
       
    93 exact copy.  The resulting work is called a "modified version" of the
       
    94 earlier work or a work "based on" the earlier work.
       
    95 
       
    96   A "covered work" means either the unmodified Program or a work based
       
    97 on the Program.
       
    98 
       
    99   To "propagate" a work means to do anything with it that, without
       
   100 permission, would make you directly or secondarily liable for
       
   101 infringement under applicable copyright law, except executing it on a
       
   102 computer or modifying a private copy.  Propagation includes copying,
       
   103 distribution (with or without modification), making available to the
       
   104 public, and in some countries other activities as well.
       
   105 
       
   106   To "convey" a work means any kind of propagation that enables other
       
   107 parties to make or receive copies.  Mere interaction with a user through
       
   108 a computer network, with no transfer of a copy, is not conveying.
       
   109 
       
   110   An interactive user interface displays "Appropriate Legal Notices"
       
   111 to the extent that it includes a convenient and prominently visible
       
   112 feature that (1) displays an appropriate copyright notice, and (2)
       
   113 tells the user that there is no warranty for the work (except to the
       
   114 extent that warranties are provided), that licensees may convey the
       
   115 work under this License, and how to view a copy of this License.  If
       
   116 the interface presents a list of user commands or options, such as a
       
   117 menu, a prominent item in the list meets this criterion.
       
   118 
       
   119   1. Source Code.
       
   120 
       
   121   The "source code" for a work means the preferred form of the work
       
   122 for making modifications to it.  "Object code" means any non-source
       
   123 form of a work.
       
   124 
       
   125   A "Standard Interface" means an interface that either is an official
       
   126 standard defined by a recognized standards body, or, in the case of
       
   127 interfaces specified for a particular programming language, one that
       
   128 is widely used among developers working in that language.
       
   129 
       
   130   The "System Libraries" of an executable work include anything, other
       
   131 than the work as a whole, that (a) is included in the normal form of
       
   132 packaging a Major Component, but which is not part of that Major
       
   133 Component, and (b) serves only to enable use of the work with that
       
   134 Major Component, or to implement a Standard Interface for which an
       
   135 implementation is available to the public in source code form.  A
       
   136 "Major Component", in this context, means a major essential component
       
   137 (kernel, window system, and so on) of the specific operating system
       
   138 (if any) on which the executable work runs, or a compiler used to
       
   139 produce the work, or an object code interpreter used to run it.
       
   140 
       
   141   The "Corresponding Source" for a work in object code form means all
       
   142 the source code needed to generate, install, and (for an executable
       
   143 work) run the object code and to modify the work, including scripts to
       
   144 control those activities.  However, it does not include the work's
       
   145 System Libraries, or general-purpose tools or generally available free
       
   146 programs which are used unmodified in performing those activities but
       
   147 which are not part of the work.  For example, Corresponding Source
       
   148 includes interface definition files associated with source files for
       
   149 the work, and the source code for shared libraries and dynamically
       
   150 linked subprograms that the work is specifically designed to require,
       
   151 such as by intimate data communication or control flow between those
       
   152 subprograms and other parts of the work.
       
   153 
       
   154   The Corresponding Source need not include anything that users
       
   155 can regenerate automatically from other parts of the Corresponding
       
   156 Source.
       
   157 
       
   158   The Corresponding Source for a work in source code form is that
       
   159 same work.
       
   160 
       
   161   2. Basic Permissions.
       
   162 
       
   163   All rights granted under this License are granted for the term of
       
   164 copyright on the Program, and are irrevocable provided the stated
       
   165 conditions are met.  This License explicitly affirms your unlimited
       
   166 permission to run the unmodified Program.  The output from running a
       
   167 covered work is covered by this License only if the output, given its
       
   168 content, constitutes a covered work.  This License acknowledges your
       
   169 rights of fair use or other equivalent, as provided by copyright law.
       
   170 
       
   171   You may make, run and propagate covered works that you do not
       
   172 convey, without conditions so long as your license otherwise remains
       
   173 in force.  You may convey covered works to others for the sole purpose
       
   174 of having them make modifications exclusively for you, or provide you
       
   175 with facilities for running those works, provided that you comply with
       
   176 the terms of this License in conveying all material for which you do
       
   177 not control copyright.  Those thus making or running the covered works
       
   178 for you must do so exclusively on your behalf, under your direction
       
   179 and control, on terms that prohibit them from making any copies of
       
   180 your copyrighted material outside their relationship with you.
       
   181 
       
   182   Conveying under any other circumstances is permitted solely under
       
   183 the conditions stated below.  Sublicensing is not allowed; section 10
       
   184 makes it unnecessary.
       
   185 
       
   186   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
       
   187 
       
   188   No covered work shall be deemed part of an effective technological
       
   189 measure under any applicable law fulfilling obligations under article
       
   190 11 of the WIPO copyright treaty adopted on 20 December 1996, or
       
   191 similar laws prohibiting or restricting circumvention of such
       
   192 measures.
       
   193 
       
   194   When you convey a covered work, you waive any legal power to forbid
       
   195 circumvention of technological measures to the extent such circumvention
       
   196 is effected by exercising rights under this License with respect to
       
   197 the covered work, and you disclaim any intention to limit operation or
       
   198 modification of the work as a means of enforcing, against the work's
       
   199 users, your or third parties' legal rights to forbid circumvention of
       
   200 technological measures.
       
   201 
       
   202   4. Conveying Verbatim Copies.
       
   203 
       
   204   You may convey verbatim copies of the Program's source code as you
       
   205 receive it, in any medium, provided that you conspicuously and
       
   206 appropriately publish on each copy an appropriate copyright notice;
       
   207 keep intact all notices stating that this License and any
       
   208 non-permissive terms added in accord with section 7 apply to the code;
       
   209 keep intact all notices of the absence of any warranty; and give all
       
   210 recipients a copy of this License along with the Program.
       
   211 
       
   212   You may charge any price or no price for each copy that you convey,
       
   213 and you may offer support or warranty protection for a fee.
       
   214 
       
   215   5. Conveying Modified Source Versions.
       
   216 
       
   217   You may convey a work based on the Program, or the modifications to
       
   218 produce it from the Program, in the form of source code under the
       
   219 terms of section 4, provided that you also meet all of these conditions:
       
   220 
       
   221     a) The work must carry prominent notices stating that you modified
       
   222     it, and giving a relevant date.
       
   223 
       
   224     b) The work must carry prominent notices stating that it is
       
   225     released under this License and any conditions added under section
       
   226     7.  This requirement modifies the requirement in section 4 to
       
   227     "keep intact all notices".
       
   228 
       
   229     c) You must license the entire work, as a whole, under this
       
   230     License to anyone who comes into possession of a copy.  This
       
   231     License will therefore apply, along with any applicable section 7
       
   232     additional terms, to the whole of the work, and all its parts,
       
   233     regardless of how they are packaged.  This License gives no
       
   234     permission to license the work in any other way, but it does not
       
   235     invalidate such permission if you have separately received it.
       
   236 
       
   237     d) If the work has interactive user interfaces, each must display
       
   238     Appropriate Legal Notices; however, if the Program has interactive
       
   239     interfaces that do not display Appropriate Legal Notices, your
       
   240     work need not make them do so.
       
   241 
       
   242   A compilation of a covered work with other separate and independent
       
   243 works, which are not by their nature extensions of the covered work,
       
   244 and which are not combined with it such as to form a larger program,
       
   245 in or on a volume of a storage or distribution medium, is called an
       
   246 "aggregate" if the compilation and its resulting copyright are not
       
   247 used to limit the access or legal rights of the compilation's users
       
   248 beyond what the individual works permit.  Inclusion of a covered work
       
   249 in an aggregate does not cause this License to apply to the other
       
   250 parts of the aggregate.
       
   251 
       
   252   6. Conveying Non-Source Forms.
       
   253 
       
   254   You may convey a covered work in object code form under the terms
       
   255 of sections 4 and 5, provided that you also convey the
       
   256 machine-readable Corresponding Source under the terms of this License,
       
   257 in one of these ways:
       
   258 
       
   259     a) Convey the object code in, or embodied in, a physical product
       
   260     (including a physical distribution medium), accompanied by the
       
   261     Corresponding Source fixed on a durable physical medium
       
   262     customarily used for software interchange.
       
   263 
       
   264     b) Convey the object code in, or embodied in, a physical product
       
   265     (including a physical distribution medium), accompanied by a
       
   266     written offer, valid for at least three years and valid for as
       
   267     long as you offer spare parts or customer support for that product
       
   268     model, to give anyone who possesses the object code either (1) a
       
   269     copy of the Corresponding Source for all the software in the
       
   270     product that is covered by this License, on a durable physical
       
   271     medium customarily used for software interchange, for a price no
       
   272     more than your reasonable cost of physically performing this
       
   273     conveying of source, or (2) access to copy the
       
   274     Corresponding Source from a network server at no charge.
       
   275 
       
   276     c) Convey individual copies of the object code with a copy of the
       
   277     written offer to provide the Corresponding Source.  This
       
   278     alternative is allowed only occasionally and noncommercially, and
       
   279     only if you received the object code with such an offer, in accord
       
   280     with subsection 6b.
       
   281 
       
   282     d) Convey the object code by offering access from a designated
       
   283     place (gratis or for a charge), and offer equivalent access to the
       
   284     Corresponding Source in the same way through the same place at no
       
   285     further charge.  You need not require recipients to copy the
       
   286     Corresponding Source along with the object code.  If the place to
       
   287     copy the object code is a network server, the Corresponding Source
       
   288     may be on a different server (operated by you or a third party)
       
   289     that supports equivalent copying facilities, provided you maintain
       
   290     clear directions next to the object code saying where to find the
       
   291     Corresponding Source.  Regardless of what server hosts the
       
   292     Corresponding Source, you remain obligated to ensure that it is
       
   293     available for as long as needed to satisfy these requirements.
       
   294 
       
   295     e) Convey the object code using peer-to-peer transmission, provided
       
   296     you inform other peers where the object code and Corresponding
       
   297     Source of the work are being offered to the general public at no
       
   298     charge under subsection 6d.
       
   299 
       
   300   A separable portion of the object code, whose source code is excluded
       
   301 from the Corresponding Source as a System Library, need not be
       
   302 included in conveying the object code work.
       
   303 
       
   304   A "User Product" is either (1) a "consumer product", which means any
       
   305 tangible personal property which is normally used for personal, family,
       
   306 or household purposes, or (2) anything designed or sold for incorporation
       
   307 into a dwelling.  In determining whether a product is a consumer product,
       
   308 doubtful cases shall be resolved in favor of coverage.  For a particular
       
   309 product received by a particular user, "normally used" refers to a
       
   310 typical or common use of that class of product, regardless of the status
       
   311 of the particular user or of the way in which the particular user
       
   312 actually uses, or expects or is expected to use, the product.  A product
       
   313 is a consumer product regardless of whether the product has substantial
       
   314 commercial, industrial or non-consumer uses, unless such uses represent
       
   315 the only significant mode of use of the product.
       
   316 
       
   317   "Installation Information" for a User Product means any methods,
       
   318 procedures, authorization keys, or other information required to install
       
   319 and execute modified versions of a covered work in that User Product from
       
   320 a modified version of its Corresponding Source.  The information must
       
   321 suffice to ensure that the continued functioning of the modified object
       
   322 code is in no case prevented or interfered with solely because
       
   323 modification has been made.
       
   324 
       
   325   If you convey an object code work under this section in, or with, or
       
   326 specifically for use in, a User Product, and the conveying occurs as
       
   327 part of a transaction in which the right of possession and use of the
       
   328 User Product is transferred to the recipient in perpetuity or for a
       
   329 fixed term (regardless of how the transaction is characterized), the
       
   330 Corresponding Source conveyed under this section must be accompanied
       
   331 by the Installation Information.  But this requirement does not apply
       
   332 if neither you nor any third party retains the ability to install
       
   333 modified object code on the User Product (for example, the work has
       
   334 been installed in ROM).
       
   335 
       
   336   The requirement to provide Installation Information does not include a
       
   337 requirement to continue to provide support service, warranty, or updates
       
   338 for a work that has been modified or installed by the recipient, or for
       
   339 the User Product in which it has been modified or installed.  Access to a
       
   340 network may be denied when the modification itself materially and
       
   341 adversely affects the operation of the network or violates the rules and
       
   342 protocols for communication across the network.
       
   343 
       
   344   Corresponding Source conveyed, and Installation Information provided,
       
   345 in accord with this section must be in a format that is publicly
       
   346 documented (and with an implementation available to the public in
       
   347 source code form), and must require no special password or key for
       
   348 unpacking, reading or copying.
       
   349 
       
   350   7. Additional Terms.
       
   351 
       
   352   "Additional permissions" are terms that supplement the terms of this
       
   353 License by making exceptions from one or more of its conditions.
       
   354 Additional permissions that are applicable to the entire Program shall
       
   355 be treated as though they were included in this License, to the extent
       
   356 that they are valid under applicable law.  If additional permissions
       
   357 apply only to part of the Program, that part may be used separately
       
   358 under those permissions, but the entire Program remains governed by
       
   359 this License without regard to the additional permissions.
       
   360 
       
   361   When you convey a copy of a covered work, you may at your option
       
   362 remove any additional permissions from that copy, or from any part of
       
   363 it.  (Additional permissions may be written to require their own
       
   364 removal in certain cases when you modify the work.)  You may place
       
   365 additional permissions on material, added by you to a covered work,
       
   366 for which you have or can give appropriate copyright permission.
       
   367 
       
   368   Notwithstanding any other provision of this License, for material you
       
   369 add to a covered work, you may (if authorized by the copyright holders of
       
   370 that material) supplement the terms of this License with terms:
       
   371 
       
   372     a) Disclaiming warranty or limiting liability differently from the
       
   373     terms of sections 15 and 16 of this License; or
       
   374 
       
   375     b) Requiring preservation of specified reasonable legal notices or
       
   376     author attributions in that material or in the Appropriate Legal
       
   377     Notices displayed by works containing it; or
       
   378 
       
   379     c) Prohibiting misrepresentation of the origin of that material, or
       
   380     requiring that modified versions of such material be marked in
       
   381     reasonable ways as different from the original version; or
       
   382 
       
   383     d) Limiting the use for publicity purposes of names of licensors or
       
   384     authors of the material; or
       
   385 
       
   386     e) Declining to grant rights under trademark law for use of some
       
   387     trade names, trademarks, or service marks; or
       
   388 
       
   389     f) Requiring indemnification of licensors and authors of that
       
   390     material by anyone who conveys the material (or modified versions of
       
   391     it) with contractual assumptions of liability to the recipient, for
       
   392     any liability that these contractual assumptions directly impose on
       
   393     those licensors and authors.
       
   394 
       
   395   All other non-permissive additional terms are considered "further
       
   396 restrictions" within the meaning of section 10.  If the Program as you
       
   397 received it, or any part of it, contains a notice stating that it is
       
   398 governed by this License along with a term that is a further
       
   399 restriction, you may remove that term.  If a license document contains
       
   400 a further restriction but permits relicensing or conveying under this
       
   401 License, you may add to a covered work material governed by the terms
       
   402 of that license document, provided that the further restriction does
       
   403 not survive such relicensing or conveying.
       
   404 
       
   405   If you add terms to a covered work in accord with this section, you
       
   406 must place, in the relevant source files, a statement of the
       
   407 additional terms that apply to those files, or a notice indicating
       
   408 where to find the applicable terms.
       
   409 
       
   410   Additional terms, permissive or non-permissive, may be stated in the
       
   411 form of a separately written license, or stated as exceptions;
       
   412 the above requirements apply either way.
       
   413 
       
   414   8. Termination.
       
   415 
       
   416   You may not propagate or modify a covered work except as expressly
       
   417 provided under this License.  Any attempt otherwise to propagate or
       
   418 modify it is void, and will automatically terminate your rights under
       
   419 this License (including any patent licenses granted under the third
       
   420 paragraph of section 11).
       
   421 
       
   422   However, if you cease all violation of this License, then your
       
   423 license from a particular copyright holder is reinstated (a)
       
   424 provisionally, unless and until the copyright holder explicitly and
       
   425 finally terminates your license, and (b) permanently, if the copyright
       
   426 holder fails to notify you of the violation by some reasonable means
       
   427 prior to 60 days after the cessation.
       
   428 
       
   429   Moreover, your license from a particular copyright holder is
       
   430 reinstated permanently if the copyright holder notifies you of the
       
   431 violation by some reasonable means, this is the first time you have
       
   432 received notice of violation of this License (for any work) from that
       
   433 copyright holder, and you cure the violation prior to 30 days after
       
   434 your receipt of the notice.
       
   435 
       
   436   Termination of your rights under this section does not terminate the
       
   437 licenses of parties who have received copies or rights from you under
       
   438 this License.  If your rights have been terminated and not permanently
       
   439 reinstated, you do not qualify to receive new licenses for the same
       
   440 material under section 10.
       
   441 
       
   442   9. Acceptance Not Required for Having Copies.
       
   443 
       
   444   You are not required to accept this License in order to receive or
       
   445 run a copy of the Program.  Ancillary propagation of a covered work
       
   446 occurring solely as a consequence of using peer-to-peer transmission
       
   447 to receive a copy likewise does not require acceptance.  However,
       
   448 nothing other than this License grants you permission to propagate or
       
   449 modify any covered work.  These actions infringe copyright if you do
       
   450 not accept this License.  Therefore, by modifying or propagating a
       
   451 covered work, you indicate your acceptance of this License to do so.
       
   452 
       
   453   10. Automatic Licensing of Downstream Recipients.
       
   454 
       
   455   Each time you convey a covered work, the recipient automatically
       
   456 receives a license from the original licensors, to run, modify and
       
   457 propagate that work, subject to this License.  You are not responsible
       
   458 for enforcing compliance by third parties with this License.
       
   459 
       
   460   An "entity transaction" is a transaction transferring control of an
       
   461 organization, or substantially all assets of one, or subdividing an
       
   462 organization, or merging organizations.  If propagation of a covered
       
   463 work results from an entity transaction, each party to that
       
   464 transaction who receives a copy of the work also receives whatever
       
   465 licenses to the work the party's predecessor in interest had or could
       
   466 give under the previous paragraph, plus a right to possession of the
       
   467 Corresponding Source of the work from the predecessor in interest, if
       
   468 the predecessor has it or can get it with reasonable efforts.
       
   469 
       
   470   You may not impose any further restrictions on the exercise of the
       
   471 rights granted or affirmed under this License.  For example, you may
       
   472 not impose a license fee, royalty, or other charge for exercise of
       
   473 rights granted under this License, and you may not initiate litigation
       
   474 (including a cross-claim or counterclaim in a lawsuit) alleging that
       
   475 any patent claim is infringed by making, using, selling, offering for
       
   476 sale, or importing the Program or any portion of it.
       
   477 
       
   478   11. Patents.
       
   479 
       
   480   A "contributor" is a copyright holder who authorizes use under this
       
   481 License of the Program or a work on which the Program is based.  The
       
   482 work thus licensed is called the contributor's "contributor version".
       
   483 
       
   484   A contributor's "essential patent claims" are all patent claims
       
   485 owned or controlled by the contributor, whether already acquired or
       
   486 hereafter acquired, that would be infringed by some manner, permitted
       
   487 by this License, of making, using, or selling its contributor version,
       
   488 but do not include claims that would be infringed only as a
       
   489 consequence of further modification of the contributor version.  For
       
   490 purposes of this definition, "control" includes the right to grant
       
   491 patent sublicenses in a manner consistent with the requirements of
       
   492 this License.
       
   493 
       
   494   Each contributor grants you a non-exclusive, worldwide, royalty-free
       
   495 patent license under the contributor's essential patent claims, to
       
   496 make, use, sell, offer for sale, import and otherwise run, modify and
       
   497 propagate the contents of its contributor version.
       
   498 
       
   499   In the following three paragraphs, a "patent license" is any express
       
   500 agreement or commitment, however denominated, not to enforce a patent
       
   501 (such as an express permission to practice a patent or covenant not to
       
   502 sue for patent infringement).  To "grant" such a patent license to a
       
   503 party means to make such an agreement or commitment not to enforce a
       
   504 patent against the party.
       
   505 
       
   506   If you convey a covered work, knowingly relying on a patent license,
       
   507 and the Corresponding Source of the work is not available for anyone
       
   508 to copy, free of charge and under the terms of this License, through a
       
   509 publicly available network server or other readily accessible means,
       
   510 then you must either (1) cause the Corresponding Source to be so
       
   511 available, or (2) arrange to deprive yourself of the benefit of the
       
   512 patent license for this particular work, or (3) arrange, in a manner
       
   513 consistent with the requirements of this License, to extend the patent
       
   514 license to downstream recipients.  "Knowingly relying" means you have
       
   515 actual knowledge that, but for the patent license, your conveying the
       
   516 covered work in a country, or your recipient's use of the covered work
       
   517 in a country, would infringe one or more identifiable patents in that
       
   518 country that you have reason to believe are valid.
       
   519   
       
   520   If, pursuant to or in connection with a single transaction or
       
   521 arrangement, you convey, or propagate by procuring conveyance of, a
       
   522 covered work, and grant a patent license to some of the parties
       
   523 receiving the covered work authorizing them to use, propagate, modify
       
   524 or convey a specific copy of the covered work, then the patent license
       
   525 you grant is automatically extended to all recipients of the covered
       
   526 work and works based on it.
       
   527 
       
   528   A patent license is "discriminatory" if it does not include within
       
   529 the scope of its coverage, prohibits the exercise of, or is
       
   530 conditioned on the non-exercise of one or more of the rights that are
       
   531 specifically granted under this License.  You may not convey a covered
       
   532 work if you are a party to an arrangement with a third party that is
       
   533 in the business of distributing software, under which you make payment
       
   534 to the third party based on the extent of your activity of conveying
       
   535 the work, and under which the third party grants, to any of the
       
   536 parties who would receive the covered work from you, a discriminatory
       
   537 patent license (a) in connection with copies of the covered work
       
   538 conveyed by you (or copies made from those copies), or (b) primarily
       
   539 for and in connection with specific products or compilations that
       
   540 contain the covered work, unless you entered into that arrangement,
       
   541 or that patent license was granted, prior to 28 March 2007.
       
   542 
       
   543   Nothing in this License shall be construed as excluding or limiting
       
   544 any implied license or other defenses to infringement that may
       
   545 otherwise be available to you under applicable patent law.
       
   546 
       
   547   12. No Surrender of Others' Freedom.
       
   548 
       
   549   If conditions are imposed on you (whether by court order, agreement or
       
   550 otherwise) that contradict the conditions of this License, they do not
       
   551 excuse you from the conditions of this License.  If you cannot convey a
       
   552 covered work so as to satisfy simultaneously your obligations under this
       
   553 License and any other pertinent obligations, then as a consequence you may
       
   554 not convey it at all.  For example, if you agree to terms that obligate you
       
   555 to collect a royalty for further conveying from those to whom you convey
       
   556 the Program, the only way you could satisfy both those terms and this
       
   557 License would be to refrain entirely from conveying the Program.
       
   558 
       
   559   13. Use with the GNU Affero General Public License.
       
   560 
       
   561   Notwithstanding any other provision of this License, you have
       
   562 permission to link or combine any covered work with a work licensed
       
   563 under version 3 of the GNU Affero General Public License into a single
       
   564 combined work, and to convey the resulting work.  The terms of this
       
   565 License will continue to apply to the part which is the covered work,
       
   566 but the special requirements of the GNU Affero General Public License,
       
   567 section 13, concerning interaction through a network will apply to the
       
   568 combination as such.
       
   569 
       
   570   14. Revised Versions of this License.
       
   571 
       
   572   The Free Software Foundation may publish revised and/or new versions of
       
   573 the GNU General Public License from time to time.  Such new versions will
       
   574 be similar in spirit to the present version, but may differ in detail to
       
   575 address new problems or concerns.
       
   576 
       
   577   Each version is given a distinguishing version number.  If the
       
   578 Program specifies that a certain numbered version of the GNU General
       
   579 Public License "or any later version" applies to it, you have the
       
   580 option of following the terms and conditions either of that numbered
       
   581 version or of any later version published by the Free Software
       
   582 Foundation.  If the Program does not specify a version number of the
       
   583 GNU General Public License, you may choose any version ever published
       
   584 by the Free Software Foundation.
       
   585 
       
   586   If the Program specifies that a proxy can decide which future
       
   587 versions of the GNU General Public License can be used, that proxy's
       
   588 public statement of acceptance of a version permanently authorizes you
       
   589 to choose that version for the Program.
       
   590 
       
   591   Later license versions may give you additional or different
       
   592 permissions.  However, no additional obligations are imposed on any
       
   593 author or copyright holder as a result of your choosing to follow a
       
   594 later version.
       
   595 
       
   596   15. Disclaimer of Warranty.
       
   597 
       
   598   THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY

   623 reviewing courts shall apply local law that most closely approximates
       
   624 an absolute waiver of all civil liability in connection with the
       
   625 Program, unless a warranty or assumption of liability accompanies a
       
   626 copy of the Program in return for a fee.

   630 	    How to Apply These Terms to Your New Programs
       
   631 
       
   632   If you develop a new program, and you want it to be of the greatest
       
   633 possible use to the public, the best way to achieve this is to make it
       
   634 free software which everyone can redistribute and change under these terms.
       
   635 
       
   636   To do so, attach the following notices to the program.  It is safest
       
   637 to attach them to the start of each source file to most effectively
       
   638 state the exclusion of warranty; and each file should have at least
       
   639 the "copyright" line and a pointer to where the full notice is found.
       
   640 
       
   641     <one line to give the program's name and a brief idea of what it does.>
       
   642     Copyright (C) <year>  <name of author>
       
   643 
       
   644     This program is free software: you can redistribute it and/or modify
       
   645     it under the terms of the GNU General Public License as published by
       
   646     the Free Software Foundation, either version 3 of the License, or
       
   647     (at your option) any later version.
       
   648 
       
   649     This program is distributed in the hope that it will be useful,
       
   650     but WITHOUT ANY WARRANTY; without even the implied warranty of
       
   651     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
       
   652     GNU General Public License for more details.
       
   653 
       
   654     You should have received a copy of the GNU General Public License
       
   655     along with this program.  If not, see <http://www.gnu.org/licenses/>.
       
   656 
       
   657 Also add information on how to contact you by electronic and paper mail.
       
   658 
       
   659   If the program does terminal interaction, make it output a short
       
   660 notice like this when it starts in an interactive mode:
       
   661 
       
   662     <program>  Copyright (C) <year>  <name of author>
       
   663     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
       
   664     This is free software, and you are welcome to redistribute it
       
   665     under certain conditions; type `show c' for details.
       
   666 
       
   667 The hypothetical commands `show w' and `show c' should show the appropriate
       
   668 parts of the General Public License.  Of course, your program's commands
       
   669 might be different; for a GUI interface, you would use an "about box".
       
   670 
       
   671   You should also get your employer (if you work as a programmer) or school,
       
   672 if any, to sign a "copyright disclaimer" for the program, if necessary.

   675 
       
   676   The GNU General Public License does not permit incorporating your program
       
   677 into proprietary programs.  If your program is a subroutine library, you
       
   678 may consider it more useful to permit linking proprietary applications with
       
   679 the library.  If this is what you want to do, use the GNU Lesser General
       
   680 Public License instead of this License.  But first, please read
