     5                     GNU GENERAL PUBLIC LICENSE
       
     6                        Version 3, 29 June 2007
       
     7 
       
     8  Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
       
     9  Everyone is permitted to copy and distribute verbatim copies
       
    10  of this license document, but changing it is not allowed.
       
    11 
       
    12                             Preamble
       
    13 
       
    14   The GNU General Public License is a free, copyleft license for
       
    15 software and other kinds of works.
       
    16 
       
    17   The licenses for most software and other practical works are designed
       
    18 to take away your freedom to share and change the works.  By contrast,
       
    19 the GNU General Public License is intended to guarantee your freedom to
       
    20 share and change all versions of a program--to make sure it remains free
       
    21 software for all its users.  We, the Free Software Foundation, use the
       
    22 GNU General Public License for most of our software; it applies also to
       
    23 any other work released this way by its authors.  You can apply it to
       
    24 your programs, too.
       
    25 
       
    26   When we speak of free software, we are referring to freedom, not
       
    27 price.  Our General Public Licenses are designed to make sure that you
       
    28 have the freedom to distribute copies of free software (and charge for
       
    29 them if you wish), that you receive source code or can get it if you
       
    30 want it, that you can change the software or use pieces of it in new
       
    31 free programs, and that you know you can do these things.
       
    32 
       
    33   To protect your rights, we need to prevent others from denying you
       
    34 these rights or asking you to surrender the rights.  Therefore, you have
       
    35 certain responsibilities if you distribute copies of the software, or if
       
    36 you modify it: responsibilities to respect the freedom of others.
       
    37 
       
    38   For example, if you distribute copies of such a program, whether
       
    39 gratis or for a fee, you must pass on to the recipients the same
       
    40 freedoms that you received.  You must make sure that they, too, receive
       
    41 or can get the source code.  And you must show them these terms so they
       
    42 know their rights.
       
    43 
       
    44   Developers that use the GNU GPL protect your rights with two steps:
       
    45 (1) assert copyright on the software, and (2) offer you this License
       
    46 giving you legal permission to copy, distribute and/or modify it.
       
    47 
       
    48   For the developers' and authors' protection, the GPL clearly explains
       
    49 that there is no warranty for this free software.  For both users' and
       
    50 authors' sake, the GPL requires that modified versions be marked as
       
    51 changed, so that their problems will not be attributed erroneously to
       
    52 authors of previous versions.
       
    53 
       
    54   Some devices are designed to deny users access to install or run
       
    55 modified versions of the software inside them, although the manufacturer
       
    56 can do so.  This is fundamentally incompatible with the aim of
       
    57 protecting users' freedom to change the software.  The systematic
       
    58 pattern of such abuse occurs in the area of products for individuals to
       
    59 use, which is precisely where it is most unacceptable.  Therefore, we
       
    60 have designed this version of the GPL to prohibit the practice for those
       
    61 products.  If such problems arise substantially in other domains, we
       
    62 stand ready to extend this provision to those domains in future versions
       
    63 of the GPL, as needed to protect the freedom of users.
       
    64 
       
    65   Finally, every program is threatened constantly by software patents.
       
    66 States should not allow patents to restrict development and use of
       
    67 software on general-purpose computers, but in those that do, we wish to
       
    68 avoid the special danger that patents applied to a free program could
       
    69 make it effectively proprietary.  To prevent this, the GPL assures that
       
    70 patents cannot be used to render the program non-free.
       
    71 
       
    72   The precise terms and conditions for copying, distribution and
       
    73 modification follow.
       
    74 
       
    75                        TERMS AND CONDITIONS
       
    76 
       
    77   0. Definitions.
       
    78 
       
    79   "This License" refers to version 3 of the GNU General Public License.
       
    80 
       
    81   "Copyright" also means copyright-like laws that apply to other kinds of
       
    82 works, such as semiconductor masks.
       
    83 
       
    84   "The Program" refers to any copyrightable work licensed under this
       
    85 License.  Each licensee is addressed as "you".  "Licensees" and
       
    86 "recipients" may be individuals or organizations.
       
    87 
       
    88   To "modify" a work means to copy from or adapt all or part of the work
       
    89 in a fashion requiring copyright permission, other than the making of an
       
    90 exact copy.  The resulting work is called a "modified version" of the
       
    91 earlier work or a work "based on" the earlier work.
       
    92 
       
    93   A "covered work" means either the unmodified Program or a work based
       
    94 on the Program.
       
    95 
       
    96   To "propagate" a work means to do anything with it that, without
       
    97 permission, would make you directly or secondarily liable for
       
    98 infringement under applicable copyright law, except executing it on a
       
    99 computer or modifying a private copy.  Propagation includes copying,
       
   100 distribution (with or without modification), making available to the
       
   101 public, and in some countries other activities as well.
       
   102 
       
   103   To "convey" a work means any kind of propagation that enables other
       
   104 parties to make or receive copies.  Mere interaction with a user through
       
   105 a computer network, with no transfer of a copy, is not conveying.
       
   106 
       
   107   An interactive user interface displays "Appropriate Legal Notices"
       
   108 to the extent that it includes a convenient and prominently visible
       
   109 feature that (1) displays an appropriate copyright notice, and (2)
       
   110 tells the user that there is no warranty for the work (except to the
       
   111 extent that warranties are provided), that licensees may convey the
       
   112 work under this License, and how to view a copy of this License.  If
       
   113 the interface presents a list of user commands or options, such as a
       
   114 menu, a prominent item in the list meets this criterion.
       
   115 
       
   116   1. Source Code.
       
   117 
       
   118   The "source code" for a work means the preferred form of the work
       
   119 for making modifications to it.  "Object code" means any non-source
       
   120 form of a work.
       
   121 
       
   122   A "Standard Interface" means an interface that either is an official
       
   123 standard defined by a recognized standards body, or, in the case of
       
   124 interfaces specified for a particular programming language, one that
       
   125 is widely used among developers working in that language.
       
   126 
       
   127   The "System Libraries" of an executable work include anything, other
       
   128 than the work as a whole, that (a) is included in the normal form of
       
   129 packaging a Major Component, but which is not part of that Major
       
   130 Component, and (b) serves only to enable use of the work with that
       
   131 Major Component, or to implement a Standard Interface for which an
       
   132 implementation is available to the public in source code form.  A
       
   133 "Major Component", in this context, means a major essential component
       
   134 (kernel, window system, and so on) of the specific operating system
       
   135 (if any) on which the executable work runs, or a compiler used to
       
   136 produce the work, or an object code interpreter used to run it.
       
   137 
       
   138   The "Corresponding Source" for a work in object code form means all
       
   139 the source code needed to generate, install, and (for an executable
       
   140 work) run the object code and to modify the work, including scripts to
       
   141 control those activities.  However, it does not include the work's
       
   142 System Libraries, or general-purpose tools or generally available free
       
   143 programs which are used unmodified in performing those activities but
       
   144 which are not part of the work.  For example, Corresponding Source
       
   145 includes interface definition files associated with source files for
       
   146 the work, and the source code for shared libraries and dynamically
       
   147 linked subprograms that the work is specifically designed to require,
       
   148 such as by intimate data communication or control flow between those
       
   149 subprograms and other parts of the work.
       
   150 
       
   151   The Corresponding Source need not include anything that users
       
   152 can regenerate automatically from other parts of the Corresponding
       
   153 Source.
       
   154 
       
   155   The Corresponding Source for a work in source code form is that
       
   156 same work.
       
   157 
       
   158   2. Basic Permissions.
       
   159 
       
   160   All rights granted under this License are granted for the term of
       
   161 copyright on the Program, and are irrevocable provided the stated
       
   162 conditions are met.  This License explicitly affirms your unlimited
       
   163 permission to run the unmodified Program.  The output from running a
       
   164 covered work is covered by this License only if the output, given its
       
   165 content, constitutes a covered work.  This License acknowledges your
       
   166 rights of fair use or other equivalent, as provided by copyright law.
       
   167 
       
   168   You may make, run and propagate covered works that you do not
       
   169 convey, without conditions so long as your license otherwise remains
       
   170 in force.  You may convey covered works to others for the sole purpose
       
   171 of having them make modifications exclusively for you, or provide you
       
   172 with facilities for running those works, provided that you comply with
       
   173 the terms of this License in conveying all material for which you do
       
   174 not control copyright.  Those thus making or running the covered works
       
   175 for you must do so exclusively on your behalf, under your direction
       
   176 and control, on terms that prohibit them from making any copies of
       
   177 your copyrighted material outside their relationship with you.
       
   178 
       
   179   Conveying under any other circumstances is permitted solely under
       
   180 the conditions stated below.  Sublicensing is not allowed; section 10
       
   181 makes it unnecessary.
       
   182 
       
   183   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
       
   184 
       
   185   No covered work shall be deemed part of an effective technological
       
   186 measure under any applicable law fulfilling obligations under article
       
   187 11 of the WIPO copyright treaty adopted on 20 December 1996, or
       
   188 similar laws prohibiting or restricting circumvention of such
       
   189 measures.
       
   190 
       
   191   When you convey a covered work, you waive any legal power to forbid
       
   192 circumvention of technological measures to the extent such circumvention
       
   193 is effected by exercising rights under this License with respect to
       
   194 the covered work, and you disclaim any intention to limit operation or
       
   195 modification of the work as a means of enforcing, against the work's
       
   196 users, your or third parties' legal rights to forbid circumvention of
       
   197 technological measures.
       
   198 
       
   199   4. Conveying Verbatim Copies.
       
   200 
       
   201   You may convey verbatim copies of the Program's source code as you
       
   202 receive it, in any medium, provided that you conspicuously and
       
   203 appropriately publish on each copy an appropriate copyright notice;
       
   204 keep intact all notices stating that this License and any
       
   205 non-permissive terms added in accord with section 7 apply to the code;
       
   206 keep intact all notices of the absence of any warranty; and give all
       
   207 recipients a copy of this License along with the Program.
       
   208 
       
   209   You may charge any price or no price for each copy that you convey,
       
   210 and you may offer support or warranty protection for a fee.
       
   211 
       
   212   5. Conveying Modified Source Versions.
       
   213 
       
   214   You may convey a work based on the Program, or the modifications to
       
   215 produce it from the Program, in the form of source code under the
       
   216 terms of section 4, provided that you also meet all of these conditions:
       
   217 
       
   218     a) The work must carry prominent notices stating that you modified
       
   219     it, and giving a relevant date.
       
   220 
       
   221     b) The work must carry prominent notices stating that it is
       
   222     released under this License and any conditions added under section
       
   223     7.  This requirement modifies the requirement in section 4 to
       
   224     "keep intact all notices".
       
   225 
       
   226     c) You must license the entire work, as a whole, under this
       
   227     License to anyone who comes into possession of a copy.  This
       
   228     License will therefore apply, along with any applicable section 7
       
   229     additional terms, to the whole of the work, and all its parts,
       
   230     regardless of how they are packaged.  This License gives no
       
   231     permission to license the work in any other way, but it does not
       
   232     invalidate such permission if you have separately received it.
       
   233 
       
   234     d) If the work has interactive user interfaces, each must display
       
   235     Appropriate Legal Notices; however, if the Program has interactive
       
   236     interfaces that do not display Appropriate Legal Notices, your
       
   237     work need not make them do so.
       
   238 
       
   239   A compilation of a covered work with other separate and independent
       
   240 works, which are not by their nature extensions of the covered work,
       
   241 and which are not combined with it such as to form a larger program,
       
   242 in or on a volume of a storage or distribution medium, is called an
       
   243 "aggregate" if the compilation and its resulting copyright are not
       
   244 used to limit the access or legal rights of the compilation's users
       
   245 beyond what the individual works permit.  Inclusion of a covered work
       
   246 in an aggregate does not cause this License to apply to the other
       
   247 parts of the aggregate.
       
   248 
       
   249   6. Conveying Non-Source Forms.
       
   250 
       
   251   You may convey a covered work in object code form under the terms
       
   252 of sections 4 and 5, provided that you also convey the
       
   253 machine-readable Corresponding Source under the terms of this License,
       
   254 in one of these ways:
       
   255 
       
   256     a) Convey the object code in, or embodied in, a physical product
       
   257     (including a physical distribution medium), accompanied by the
       
   258     Corresponding Source fixed on a durable physical medium
       
   259     customarily used for software interchange.
       
   260 
       
   261     b) Convey the object code in, or embodied in, a physical product
       
   262     (including a physical distribution medium), accompanied by a
       
   263     written offer, valid for at least three years and valid for as
       
   264     long as you offer spare parts or customer support for that product
       
   265     model, to give anyone who possesses the object code either (1) a
       
   266     copy of the Corresponding Source for all the software in the
       
   267     product that is covered by this License, on a durable physical
       
   268     medium customarily used for software interchange, for a price no
       
   269     more than your reasonable cost of physically performing this
       
   270     conveying of source, or (2) access to copy the
       
   271     Corresponding Source from a network server at no charge.
       
   272 
       
   273     c) Convey individual copies of the object code with a copy of the
       
   274     written offer to provide the Corresponding Source.  This
       
   275     alternative is allowed only occasionally and noncommercially, and
       
   276     only if you received the object code with such an offer, in accord
       
   277     with subsection 6b.
       
   278 
       
   279     d) Convey the object code by offering access from a designated
       
   280     place (gratis or for a charge), and offer equivalent access to the
       
   281     Corresponding Source in the same way through the same place at no
       
   282     further charge.  You need not require recipients to copy the
       
   283     Corresponding Source along with the object code.  If the place to
       
   284     copy the object code is a network server, the Corresponding Source
       
   285     may be on a different server (operated by you or a third party)
       
   286     that supports equivalent copying facilities, provided you maintain
       
   287     clear directions next to the object code saying where to find the
       
   288     Corresponding Source.  Regardless of what server hosts the
       
   289     Corresponding Source, you remain obligated to ensure that it is
       
   290     available for as long as needed to satisfy these requirements.
       
   291 
       
   292     e) Convey the object code using peer-to-peer transmission, provided
       
   293     you inform other peers where the object code and Corresponding
       
   294     Source of the work are being offered to the general public at no
       
   295     charge under subsection 6d.
       
   296 
       
   297   A separable portion of the object code, whose source code is excluded
       
   298 from the Corresponding Source as a System Library, need not be
       
   299 included in conveying the object code work.
       
   300 
       
   301   A "User Product" is either (1) a "consumer product", which means any
       
   302 tangible personal property which is normally used for personal, family,
       
   303 or household purposes, or (2) anything designed or sold for incorporation
       
   304 into a dwelling.  In determining whether a product is a consumer product,
       
   305 doubtful cases shall be resolved in favor of coverage.  For a particular
       
   306 product received by a particular user, "normally used" refers to a
       
   307 typical or common use of that class of product, regardless of the status
       
   308 of the particular user or of the way in which the particular user
       
   309 actually uses, or expects or is expected to use, the product.  A product
       
   310 is a consumer product regardless of whether the product has substantial
       
   311 commercial, industrial or non-consumer uses, unless such uses represent
       
   312 the only significant mode of use of the product.
       
   313 
       
   314   "Installation Information" for a User Product means any methods,
       
   315 procedures, authorization keys, or other information required to install
       
   316 and execute modified versions of a covered work in that User Product from
       
   317 a modified version of its Corresponding Source.  The information must
       
   318 suffice to ensure that the continued functioning of the modified object
       
   319 code is in no case prevented or interfered with solely because
       
   320 modification has been made.
       
   321 
       
   322   If you convey an object code work under this section in, or with, or
       
   323 specifically for use in, a User Product, and the conveying occurs as
       
   324 part of a transaction in which the right of possession and use of the
       
   325 User Product is transferred to the recipient in perpetuity or for a
       
   326 fixed term (regardless of how the transaction is characterized), the
       
   327 Corresponding Source conveyed under this section must be accompanied
       
   328 by the Installation Information.  But this requirement does not apply
       
   329 if neither you nor any third party retains the ability to install
       
   330 modified object code on the User Product (for example, the work has
       
   331 been installed in ROM).
       
   332 
       
   333   The requirement to provide Installation Information does not include a
       
   334 requirement to continue to provide support service, warranty, or updates
       
   335 for a work that has been modified or installed by the recipient, or for
       
   336 the User Product in which it has been modified or installed.  Access to a
       
   337 network may be denied when the modification itself materially and
       
   338 adversely affects the operation of the network or violates the rules and
       
   339 protocols for communication across the network.
       
   340 
       
   341   Corresponding Source conveyed, and Installation Information provided,
       
   342 in accord with this section must be in a format that is publicly
       
   343 documented (and with an implementation available to the public in
       
   344 source code form), and must require no special password or key for
       
   345 unpacking, reading or copying.
       
   346 
       
   347   7. Additional Terms.
       
   348 
       
   349   "Additional permissions" are terms that supplement the terms of this
       
   350 License by making exceptions from one or more of its conditions.
       
   351 Additional permissions that are applicable to the entire Program shall
       
   352 be treated as though they were included in this License, to the extent
       
   353 that they are valid under applicable law.  If additional permissions
       
   354 apply only to part of the Program, that part may be used separately
       
   355 under those permissions, but the entire Program remains governed by
       
   356 this License without regard to the additional permissions.
       
   357 
       
   358   When you convey a copy of a covered work, you may at your option
       
   359 remove any additional permissions from that copy, or from any part of
       
   360 it.  (Additional permissions may be written to require their own
       
   361 removal in certain cases when you modify the work.)  You may place
       
   362 additional permissions on material, added by you to a covered work,
       
   363 for which you have or can give appropriate copyright permission.
       
   364 
       
   365   Notwithstanding any other provision of this License, for material you
       
   366 add to a covered work, you may (if authorized by the copyright holders of
       
   367 that material) supplement the terms of this License with terms:
       
   368 
       
   369     a) Disclaiming warranty or limiting liability differently from the
       
   370     terms of sections 15 and 16 of this License; or
       
   371 
       
   372     b) Requiring preservation of specified reasonable legal notices or
       
   373     author attributions in that material or in the Appropriate Legal
       
   374     Notices displayed by works containing it; or
       
   375 
       
   376     c) Prohibiting misrepresentation of the origin of that material, or
       
   377     requiring that modified versions of such material be marked in
       
   378     reasonable ways as different from the original version; or
       
   379 
       
   380     d) Limiting the use for publicity purposes of names of licensors or
       
   381     authors of the material; or
       
   382 
       
   383     e) Declining to grant rights under trademark law for use of some
       
   384     trade names, trademarks, or service marks; or
       
   385 
       
   386     f) Requiring indemnification of licensors and authors of that
       
   387     material by anyone who conveys the material (or modified versions of
       
   388     it) with contractual assumptions of liability to the recipient, for
       
   389     any liability that these contractual assumptions directly impose on
       
   390     those licensors and authors.
       
   391 
       
   392   All other non-permissive additional terms are considered "further
       
   393 restrictions" within the meaning of section 10.  If the Program as you
       
   394 received it, or any part of it, contains a notice stating that it is
       
   395 governed by this License along with a term that is a further
       
   396 restriction, you may remove that term.  If a license document contains
       
   397 a further restriction but permits relicensing or conveying under this
       
   398 License, you may add to a covered work material governed by the terms
       
   399 of that license document, provided that the further restriction does
       
   400 not survive such relicensing or conveying.
       
   401 
       
   402   If you add terms to a covered work in accord with this section, you
       
   403 must place, in the relevant source files, a statement of the
       
   404 additional terms that apply to those files, or a notice indicating
       
   405 where to find the applicable terms.
       
   406 
       
   407   Additional terms, permissive or non-permissive, may be stated in the
       
   408 form of a separately written license, or stated as exceptions;
       
   409 the above requirements apply either way.
       
   410 
       
   411   8. Termination.
       
   412 
       
   413   You may not propagate or modify a covered work except as expressly
       
   414 provided under this License.  Any attempt otherwise to propagate or
       
   415 modify it is void, and will automatically terminate your rights under
       
   416 this License (including any patent licenses granted under the third
       
   417 paragraph of section 11).
       
   418 
       
   419   However, if you cease all violation of this License, then your
       
   420 license from a particular copyright holder is reinstated (a)
       
   421 provisionally, unless and until the copyright holder explicitly and
       
   422 finally terminates your license, and (b) permanently, if the copyright
       
   423 holder fails to notify you of the violation by some reasonable means
       
   424 prior to 60 days after the cessation.
       
   425 
       
   426   Moreover, your license from a particular copyright holder is
       
   427 reinstated permanently if the copyright holder notifies you of the
       
   428 violation by some reasonable means, this is the first time you have
       
   429 received notice of violation of this License (for any work) from that
       
   430 copyright holder, and you cure the violation prior to 30 days after
       
   431 your receipt of the notice.
       
   432 
       
   433   Termination of your rights under this section does not terminate the
       
   434 licenses of parties who have received copies or rights from you under
       
   435 this License.  If your rights have been terminated and not permanently
       
   436 reinstated, you do not qualify to receive new licenses for the same
       
   437 material under section 10.
       
   438 
       
   439   9. Acceptance Not Required for Having Copies.
       
   440 
       
   441   You are not required to accept this License in order to receive or
       
   442 run a copy of the Program.  Ancillary propagation of a covered work
       
   443 occurring solely as a consequence of using peer-to-peer transmission
       
   444 to receive a copy likewise does not require acceptance.  However,
       
   445 nothing other than this License grants you permission to propagate or
       
   446 modify any covered work.  These actions infringe copyright if you do
       
   447 not accept this License.  Therefore, by modifying or propagating a
       
   448 covered work, you indicate your acceptance of this License to do so.
       
   449 
       
   450   10. Automatic Licensing of Downstream Recipients.
       
   451 
       
   452   Each time you convey a covered work, the recipient automatically
       
   453 receives a license from the original licensors, to run, modify and
       
   454 propagate that work, subject to this License.  You are not responsible
       
   455 for enforcing compliance by third parties with this License.
       
   456 
       
   457   An "entity transaction" is a transaction transferring control of an
       
   458 organization, or substantially all assets of one, or subdividing an
       
   459 organization, or merging organizations.  If propagation of a covered
       
   460 work results from an entity transaction, each party to that
       
   461 transaction who receives a copy of the work also receives whatever
       
   462 licenses to the work the party's predecessor in interest had or could
       
   463 give under the previous paragraph, plus a right to possession of the
       
   464 Corresponding Source of the work from the predecessor in interest, if
       
   465 the predecessor has it or can get it with reasonable efforts.
       
   466 
       
   467   You may not impose any further restrictions on the exercise of the
       
   468 rights granted or affirmed under this License.  For example, you may
       
   469 not impose a license fee, royalty, or other charge for exercise of
       
   470 rights granted under this License, and you may not initiate litigation
       
   471 (including a cross-claim or counterclaim in a lawsuit) alleging that
       
   472 any patent claim is infringed by making, using, selling, offering for
       
   473 sale, or importing the Program or any portion of it.
       
   474 
       
   475   11. Patents.
       
   476 
       
   477   A "contributor" is a copyright holder who authorizes use under this
       
   478 License of the Program or a work on which the Program is based.  The
       
   479 work thus licensed is called the contributor's "contributor version".
       
   480 
       
   481   A contributor's "essential patent claims" are all patent claims
       
   482 owned or controlled by the contributor, whether already acquired or
       
   483 hereafter acquired, that would be infringed by some manner, permitted
       
   484 by this License, of making, using, or selling its contributor version,
       
   485 but do not include claims that would be infringed only as a
       
   486 consequence of further modification of the contributor version.  For
       
   487 purposes of this definition, "control" includes the right to grant
       
   488 patent sublicenses in a manner consistent with the requirements of
       
   489 this License.
       
   490 
       
   491   Each contributor grants you a non-exclusive, worldwide, royalty-free
       
   492 patent license under the contributor's essential patent claims, to
       
   493 make, use, sell, offer for sale, import and otherwise run, modify and
       
   494 propagate the contents of its contributor version.
       
   495 
       
   496   In the following three paragraphs, a "patent license" is any express
       
   497 agreement or commitment, however denominated, not to enforce a patent
       
   498 (such as an express permission to practice a patent or covenant not to
       
   499 sue for patent infringement).  To "grant" such a patent license to a
       
   500 party means to make such an agreement or commitment not to enforce a
       
   501 patent against the party.
       
   502 
       
   503   If you convey a covered work, knowingly relying on a patent license,
       
   504 and the Corresponding Source of the work is not available for anyone
       
   505 to copy, free of charge and under the terms of this License, through a
       
   506 publicly available network server or other readily accessible means,
       
   507 then you must either (1) cause the Corresponding Source to be so
       
   508 available, or (2) arrange to deprive yourself of the benefit of the
       
   509 patent license for this particular work, or (3) arrange, in a manner
       
   510 consistent with the requirements of this License, to extend the patent
       
   511 license to downstream recipients.  "Knowingly relying" means you have
       
   512 actual knowledge that, but for the patent license, your conveying the
       
   513 covered work in a country, or your recipient's use of the covered work
       
   514 in a country, would infringe one or more identifiable patents in that
       
   515 country that you have reason to believe are valid.
       
   516 
       
   517   If, pursuant to or in connection with a single transaction or
       
   518 arrangement, you convey, or propagate by procuring conveyance of, a
       
   519 covered work, and grant a patent license to some of the parties
       
   520 receiving the covered work authorizing them to use, propagate, modify
       
   521 or convey a specific copy of the covered work, then the patent license
       
   522 you grant is automatically extended to all recipients of the covered
       
   523 work and works based on it.
       
   524 
       
   525   A patent license is "discriminatory" if it does not include within
       
   526 the scope of its coverage, prohibits the exercise of, or is
       
   527 conditioned on the non-exercise of one or more of the rights that are
       
   528 specifically granted under this License.  You may not convey a covered
       
   529 work if you are a party to an arrangement with a third party that is
       
   530 in the business of distributing software, under which you make payment
       
   531 to the third party based on the extent of your activity of conveying
       
   532 the work, and under which the third party grants, to any of the
       
   533 parties who would receive the covered work from you, a discriminatory
       
   534 patent license (a) in connection with copies of the covered work
       
   535 conveyed by you (or copies made from those copies), or (b) primarily
       
   536 for and in connection with specific products or compilations that
       
   537 contain the covered work, unless you entered into that arrangement,
       
   538 or that patent license was granted, prior to 28 March 2007.
       
   539 
       
   540   Nothing in this License shall be construed as excluding or limiting
       
   541 any implied license or other defenses to infringement that may
       
   542 otherwise be available to you under applicable patent law.
       
   543 
       
   544   12. No Surrender of Others' Freedom.
       
   545 
       
   546   If conditions are imposed on you (whether by court order, agreement or
       
   547 otherwise) that contradict the conditions of this License, they do not
       
   548 excuse you from the conditions of this License.  If you cannot convey a
       
   549 covered work so as to satisfy simultaneously your obligations under this
       
   550 License and any other pertinent obligations, then as a consequence you may
       
   551 not convey it at all.  For example, if you agree to terms that obligate you
       
   552 to collect a royalty for further conveying from those to whom you convey
       
   553 the Program, the only way you could satisfy both those terms and this
       
   554 License would be to refrain entirely from conveying the Program.
       
   555 
       
   556   13. Use with the GNU Affero General Public License.
       
   557 
       
   558   Notwithstanding any other provision of this License, you have
       
   559 permission to link or combine any covered work with a work licensed
       
   560 under version 3 of the GNU Affero General Public License into a single
       
   561 combined work, and to convey the resulting work.  The terms of this
       
   562 License will continue to apply to the part which is the covered work,
       
   563 but the special requirements of the GNU Affero General Public License,
       
   564 section 13, concerning interaction through a network will apply to the
       
   565 combination as such.
       
   566 
       
   567   14. Revised Versions of this License.
       
   568 
       
   569   The Free Software Foundation may publish revised and/or new versions of
       
   570 the GNU General Public License from time to time.  Such new versions will
       
   571 be similar in spirit to the present version, but may differ in detail to
       
   572 address new problems or concerns.
       
   573 
       
   574   Each version is given a distinguishing version number.  If the
       
   575 Program specifies that a certain numbered version of the GNU General
       
   576 Public License "or any later version" applies to it, you have the
       
   577 option of following the terms and conditions either of that numbered
       
   578 version or of any later version published by the Free Software
       
   579 Foundation.  If the Program does not specify a version number of the
       
   580 GNU General Public License, you may choose any version ever published
       
   581 by the Free Software Foundation.
       
   582 
       
   583   If the Program specifies that a proxy can decide which future
       
   584 versions of the GNU General Public License can be used, that proxy's
       
   585 public statement of acceptance of a version permanently authorizes you
       
   586 to choose that version for the Program.
       
   587 
       
   588   Later license versions may give you additional or different
       
   589 permissions.  However, no additional obligations are imposed on any
       
   590 author or copyright holder as a result of your choosing to follow a
       
   591 later version.
       
   592 
       
   593   15. Disclaimer of Warranty.
       
   594 
       
   595   THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
       
   596 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
       
   597 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
       
   598 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
       
   599 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
       
   600 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
       
   601 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
       
   602 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
       
   603 
       
   604   16. Limitation of Liability.
       
   605 
       
   606   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
       
   607 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
       
   608 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
       
   609 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
       
   610 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
       
   611 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
       
   612 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
       
   613 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
       
   614 SUCH DAMAGES.
       
   615 
       
   616   17. Interpretation of Sections 15 and 16.
       
   617 
       
   618   If the disclaimer of warranty and limitation of liability provided
       
   619 above cannot be given local legal effect according to their terms,
       
   620 reviewing courts shall apply local law that most closely approximates
       
   621 an absolute waiver of all civil liability in connection with the
       
   622 Program, unless a warranty or assumption of liability accompanies a
       
   623 copy of the Program in return for a fee.
       
   624 
       
   625                      END OF TERMS AND CONDITIONS
       
   626 
       
   627             How to Apply These Terms to Your New Programs
       
   628 
       
   629   If you develop a new program, and you want it to be of the greatest
       
   630 possible use to the public, the best way to achieve this is to make it
       
   631 free software which everyone can redistribute and change under these terms.
       
   632 
       
   633   To do so, attach the following notices to the program.  It is safest
       
   634 to attach them to the start of each source file to most effectively
       
   635 state the exclusion of warranty; and each file should have at least
       
   636 the "copyright" line and a pointer to where the full notice is found.
       
   637 
       
   638     <one line to give the program's name and a brief idea of what it does.>

   647     but WITHOUT ANY WARRANTY; without even the implied warranty of

   650 
       
   651     You should have received a copy of the GNU General Public License

   653 
       
   654 Also add information on how to contact you by electronic and paper mail.
       
   655 
       
   656   If the program does terminal interaction, make it output a short
       
   657 notice like this when it starts in an interactive mode:
       
   658 
       
   659     <program>  Copyright (C) <year>  <name of author>
       
   660     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.

   663 
       
   664 The hypothetical commands `show w' and `show c' should show the appropriate
       
   665 parts of the General Public License.  Of course, your program's commands
       
   666 might be different; for a GUI interface, you would use an "about box".
       
   667 
       
   668   You should also get your employer (if you work as a programmer) or school,
       
   669 if any, to sign a "copyright disclaimer" for the program, if necessary.

   673   The GNU General Public License does not permit incorporating your program
       
   674 into proprietary programs.  If your program is a subroutine library, you
       
   675 may consider it more useful to permit linking proprietary applications with
       
   676 the library.  If this is what you want to do, use the GNU Lesser General

   687  Everyone is permitted to copy and distribute verbatim copies
       
   688  of this license document, but changing it is not allowed.
       
   689 
       
   690                             Preamble
       
   691 
       
   692   The licenses for most software are designed to take away your
       
   693 freedom to share and change it.  By contrast, the GNU General Public
       
   694 License is intended to guarantee your freedom to share and change free
       
   695 software--to make sure the software is free for all its users.  This
       
   696 General Public License applies to most of the Free Software
       
   697 Foundation's software and to any other program whose authors commit to
       
   698 using it.  (Some other Free Software Foundation software is covered by
       
   699 the GNU Lesser General Public License instead.)  You can apply it to
       
   700 your programs, too.
       
   701 
       
   702   When we speak of free software, we are referring to freedom, not
       
   703 price.  Our General Public Licenses are designed to make sure that you
       
   704 have the freedom to distribute copies of free software (and charge for
       
   705 this service if you wish), that you receive source code or can get it
       
   706 if you want it, that you can change the software or use pieces of it
       
   707 in new free programs; and that you know you can do these things.
       
   708 
       
   709   To protect your rights, we need to make restrictions that forbid
       
   710 anyone to deny you these rights or to ask you to surrender the rights.
       
   711 These restrictions translate to certain responsibilities for you if you
       
   712 distribute copies of the software, or if you modify it.
       
   713 
       
   714   For example, if you distribute copies of such a program, whether
       
   715 gratis or for a fee, you must give the recipients all the rights that
       
   716 you have.  You must make sure that they, too, receive or can get the
       
   717 source code.  And you must show them these terms so they know their
       
   718 rights.
       
   719 
       
   720   We protect your rights with two steps: (1) copyright the software, and
       
   721 (2) offer you this license which gives you legal permission to copy,
       
   722 distribute and/or modify the software.
       
   723 
       
   724   Also, for each author's protection and ours, we want to make certain
       
   725 that everyone understands that there is no warranty for this free
       
   726 software.  If the software is modified by someone else and passed on, we
       
   727 want its recipients to know that what they have is not the original, so
       
   728 that any problems introduced by others will not reflect on the original
       
   729 authors' reputations.
       
   730 
       
   731   Finally, any free program is threatened constantly by software
       
   732 patents.  We wish to avoid the danger that redistributors of a free
       
   733 program will individually obtain patent licenses, in effect making the
       
   734 program proprietary.  To prevent this, we have made it clear that any
       
   735 patent must be licensed for everyone's free use or not licensed at all.
       
   736 
       
   737   The precise terms and conditions for copying, distribution and
       
   738 modification follow.
       
   739 
       
   740                     GNU GENERAL PUBLIC LICENSE
       
   741    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
       
   742 
       
   743   0. This License applies to any program or other work which contains
       
   744 a notice placed by the copyright holder saying it may be distributed
       
   745 under the terms of this General Public License.  The "Program", below,
       
   746 refers to any such program or work, and a "work based on the Program"
       
   747 means either the Program or any derivative work under copyright law:
       
   748 that is to say, a work containing the Program or a portion of it,
       
   749 either verbatim or with modifications and/or translated into another
       
   750 language.  (Hereinafter, translation is included without limitation in
       
   751 the term "modification".)  Each licensee is addressed as "you".
       
   752 
       
   753 Activities other than copying, distribution and modification are not
       
   754 covered by this License; they are outside its scope.  The act of
       
   755 running the Program is not restricted, and the output from the Program
       
   756 is covered only if its contents constitute a work based on the
       
   757 Program (independent of having been made by running the Program).
       
   758 Whether that is true depends on what the Program does.
       
   759 
       
   760   1. You may copy and distribute verbatim copies of the Program's
       
   761 source code as you receive it, in any medium, provided that you
       
   762 conspicuously and appropriately publish on each copy an appropriate
       
   763 copyright notice and disclaimer of warranty; keep intact all the
       
   764 notices that refer to this License and to the absence of any warranty;
       
   765 and give any other recipients of the Program a copy of this License
       
   766 along with the Program.
       
   767 
       
   768 You may charge a fee for the physical act of transferring a copy, and
       
   769 you may at your option offer warranty protection in exchange for a fee.
       
   770 
       
   771   2. You may modify your copy or copies of the Program or any portion
       
   772 of it, thus forming a work based on the Program, and copy and
       
   773 distribute such modifications or work under the terms of Section 1
       
   774 above, provided that you also meet all of these conditions:
       
   775 
       
   776     a) You must cause the modified files to carry prominent notices
       
   777     stating that you changed the files and the date of any change.
       
   778 
       
   779     b) You must cause any work that you distribute or publish, that in
       
   780     whole or in part contains or is derived from the Program or any
       
   781     part thereof, to be licensed as a whole at no charge to all third
       
   782     parties under the terms of this License.
       
   783 
       
   784     c) If the modified program normally reads commands interactively
       
   785     when run, you must cause it, when started running for such
       
   786     interactive use in the most ordinary way, to print or display an
       
   787     announcement including an appropriate copyright notice and a
       
   788     notice that there is no warranty (or else, saying that you provide
       
   789     a warranty) and that users may redistribute the program under
       
   790     these conditions, and telling the user how to view a copy of this
       
   791     License.  (Exception: if the Program itself is interactive but
       
   792     does not normally print such an announcement, your work based on
       
   793     the Program is not required to print an announcement.)
       
   794 
       
   795 These requirements apply to the modified work as a whole.  If
       
   796 identifiable sections of that work are not derived from the Program,
       
   797 and can be reasonably considered independent and separate works in
       
   798 themselves, then this License, and its terms, do not apply to those
       
   799 sections when you distribute them as separate works.  But when you
       
   800 distribute the same sections as part of a whole which is a work based
       
   801 on the Program, the distribution of the whole must be on the terms of
       
   802 this License, whose permissions for other licensees extend to the
       
   803 entire whole, and thus to each and every part regardless of who wrote it.
       
   804 
       
   805 Thus, it is not the intent of this section to claim rights or contest
       
   806 your rights to work written entirely by you; rather, the intent is to
       
   807 exercise the right to control the distribution of derivative or
       
   808 collective works based on the Program.
       
   809 
       
   810 In addition, mere aggregation of another work not based on the Program
       
   811 with the Program (or with a work based on the Program) on a volume of
       
   812 a storage or distribution medium does not bring the other work under
       
   813 the scope of this License.
       
   814 
       
   815   3. You may copy and distribute the Program (or a work based on it,
       
   816 under Section 2) in object code or executable form under the terms of
       
   817 Sections 1 and 2 above provided that you also do one of the following:
       
   818 
       
   819     a) Accompany it with the complete corresponding machine-readable
       
   820     source code, which must be distributed under the terms of Sections
       
   821     1 and 2 above on a medium customarily used for software interchange; or,
       
   822 
       
   823     b) Accompany it with a written offer, valid for at least three
       
   824     years, to give any third party, for a charge no more than your
       
   825     cost of physically performing source distribution, a complete
       
   826     machine-readable copy of the corresponding source code, to be
       
   827     distributed under the terms of Sections 1 and 2 above on a medium
       
   828     customarily used for software interchange; or,
       
   829 
       
   830     c) Accompany it with the information you received as to the offer
       
   831     to distribute corresponding source code.  (This alternative is
       
   832     allowed only for noncommercial distribution and only if you
       
   833     received the program in object code or executable form with such
       
   834     an offer, in accord with Subsection b above.)
       
   835 
       
   836 The source code for a work means the preferred form of the work for
       
   837 making modifications to it.  For an executable work, complete source
       
   838 code means all the source code for all modules it contains, plus any
       
   839 associated interface definition files, plus the scripts used to
       
   840 control compilation and installation of the executable.  However, as a
       
   841 special exception, the source code distributed need not include
       
   842 anything that is normally distributed (in either source or binary
       
   843 form) with the major components (compiler, kernel, and so on) of the
       
   844 operating system on which the executable runs, unless that component
       
   845 itself accompanies the executable.
       
   846 
       
   847 If distribution of executable or object code is made by offering
       
   848 access to copy from a designated place, then offering equivalent
       
   849 access to copy the source code from the same place counts as
       
   850 distribution of the source code, even though third parties are not
       
   851 compelled to copy the source along with the object code.
       
   852 
       
   853   4. You may not copy, modify, sublicense, or distribute the Program
       
   854 except as expressly provided under this License.  Any attempt
       
   855 otherwise to copy, modify, sublicense or distribute the Program is
       
   856 void, and will automatically terminate your rights under this License.
       
   857 However, parties who have received copies, or rights, from you under
       
   858 this License will not have their licenses terminated so long as such
       
   859 parties remain in full compliance.
       
   860 
       
   861   5. You are not required to accept this License, since you have not
       
   862 signed it.  However, nothing else grants you permission to modify or
       
   863 distribute the Program or its derivative works.  These actions are
       
   864 prohibited by law if you do not accept this License.  Therefore, by
       
   865 modifying or distributing the Program (or any work based on the
       
   866 Program), you indicate your acceptance of this License to do so, and
       
   867 all its terms and conditions for copying, distributing or modifying
       
   868 the Program or works based on it.
       
   869 
       
   870   6. Each time you redistribute the Program (or any work based on the
       
   871 Program), the recipient automatically receives a license from the
       
   872 original licensor to copy, distribute or modify the Program subject to
       
   873 these terms and conditions.  You may not impose any further
       
   874 restrictions on the recipients' exercise of the rights granted herein.
       
   875 You are not responsible for enforcing compliance by third parties to
       
   876 this License.
       
   877 
       
   878   7. If, as a consequence of a court judgment or allegation of patent
       
   879 infringement or for any other reason (not limited to patent issues),
       
   880 conditions are imposed on you (whether by court order, agreement or
       
   881 otherwise) that contradict the conditions of this License, they do not
       
   882 excuse you from the conditions of this License.  If you cannot
       
   883 distribute so as to satisfy simultaneously your obligations under this
       
   884 License and any other pertinent obligations, then as a consequence you
       
   885 may not distribute the Program at all.  For example, if a patent
       
   886 license would not permit royalty-free redistribution of the Program by
       
   887 all those who receive copies directly or indirectly through you, then
       
   888 the only way you could satisfy both it and this License would be to
       
   889 refrain entirely from distribution of the Program.
       
   890 
       
   891 If any portion of this section is held invalid or unenforceable under
       
   892 any particular circumstance, the balance of the section is intended to
       
   893 apply and the section as a whole is intended to apply in other
       
   894 circumstances.
       
   895 
       
   896 It is not the purpose of this section to induce you to infringe any
       
   897 patents or other property right claims or to contest validity of any
       
   898 such claims; this section has the sole purpose of protecting the
       
   899 integrity of the free software distribution system, which is
       
   900 implemented by public license practices.  Many people have made
       
   901 generous contributions to the wide range of software distributed
       
   902 through that system in reliance on consistent application of that
       
   903 system; it is up to the author/donor to decide if he or she is willing
       
   904 to distribute software through any other system and a licensee cannot
       
   905 impose that choice.
       
   906 
       
   907 This section is intended to make thoroughly clear what is believed to
       
   908 be a consequence of the rest of this License.
       
   909 
       
   910   8. If the distribution and/or use of the Program is restricted in
       
   911 certain countries either by patents or by copyrighted interfaces, the
       
   912 original copyright holder who places the Program under this License
       
   913 may add an explicit geographical distribution limitation excluding
       
   914 those countries, so that distribution is permitted only in or among
       
   915 countries not thus excluded.  In such case, this License incorporates
       
   916 the limitation as if written in the body of this License.
       
   917 
       
   918   9. The Free Software Foundation may publish revised and/or new versions
       
   919 of the General Public License from time to time.  Such new versions will
       
   920 be similar in spirit to the present version, but may differ in detail to
       
   921 address new problems or concerns.
       
   922 
       
   923 Each version is given a distinguishing version number.  If the Program
       
   924 specifies a version number of this License which applies to it and "any
       
   925 later version", you have the option of following the terms and conditions
       
   926 either of that version or of any later version published by the Free
       
   927 Software Foundation.  If the Program does not specify a version number of
       
   928 this License, you may choose any version ever published by the Free Software
       
   929 Foundation.
       
   930 
       
   931   10. If you wish to incorporate parts of the Program into other free
       
   932 programs whose distribution conditions are different, write to the author
       
   933 to ask for permission.  For software which is copyrighted by the Free
       
   934 Software Foundation, write to the Free Software Foundation; we sometimes
       
   935 make exceptions for this.  Our decision will be guided by the two goals
       
   936 of preserving the free status of all derivatives of our free software and
       
   937 of promoting the sharing and reuse of software generally.
       
   938 
       
   939                             NO WARRANTY
       
   940 
       
   941   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
       
   942 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
       
   943 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
       
   944 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
       
   945 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
       
   946 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
       
   947 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
       
   948 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
       
   949 REPAIR OR CORRECTION.
       
   950 
       
   951   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
       
   952 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
       
   953 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
       
   954 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
       
   955 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
       
   956 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
       
   957 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
       
   958 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
       
   959 POSSIBILITY OF SUCH DAMAGES.
       
   960 
       
   961                      END OF TERMS AND CONDITIONS
       
   962 
       
   963             How to Apply These Terms to Your New Programs
       
   964 
       
   965   If you develop a new program, and you want it to be of the greatest
       
   966 possible use to the public, the best way to achieve this is to make it
       
   967 free software which everyone can redistribute and change under these terms.
       
   968 
       
   969   To do so, attach the following notices to the program.  It is safest
       
   970 to attach them to the start of each source file to most effectively
       
   971 convey the exclusion of warranty; and each file should have at least
       
   972 the "copyright" line and a pointer to where the full notice is found.
       
   973 
       
   974     <one line to give the program's name and a brief idea of what it does.>
       
   975     Copyright (C) <year>  <name of author>
       
   976 
       
   977     This program is free software; you can redistribute it and/or modify
       
   978     it under the terms of the GNU General Public License as published by
       
   979     the Free Software Foundation; either version 2 of the License, or
       
   980     (at your option) any later version.
       
   981 
       
   982     This program is distributed in the hope that it will be useful,
       
   983     but WITHOUT ANY WARRANTY; without even the implied warranty of
       
   984     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
       
   985     GNU General Public License for more details.
       
   986 
       
   987     You should have received a copy of the GNU General Public License along
       
   988     with this program; if not, write to the Free Software Foundation, Inc.,
       
   989     51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
       
   990 
       
   991 Also add information on how to contact you by electronic and paper mail.
       
   992 
       
   993 If the program is interactive, make it output a short notice like this
       
   994 when it starts in an interactive mode:
       
   995 
       
   996     Gnomovision version 69, Copyright (C) year name of author
       
   997     Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
       
   998     This is free software, and you are welcome to redistribute it
       
   999     under certain conditions; type `show c' for details.
       
  1000 
       
  1001 The hypothetical commands `show w' and `show c' should show the appropriate
       
  1002 parts of the General Public License.  Of course, the commands you use may
       
  1003 be called something other than `show w' and `show c'; they could even be
       
  1004 mouse-clicks or menu items--whatever suits your program.
       
  1005 
       
  1006 You should also get your employer (if you work as a programmer) or your
       
  1007 school, if any, to sign a "copyright disclaimer" for the program, if
       
  1008 necessary.  Here is a sample; alter the names:
       
  1009 
       
  1010   Yoyodyne, Inc., hereby disclaims all copyright interest in the program
       
  1011   `Gnomovision' (which makes passes at compilers) written by James Hacker.

  1016 This General Public License does not permit incorporating your program into
       
  1017 proprietary programs.  If your program is a subroutine library, you may
       
  1018 consider it more useful to permit linking proprietary applications with the
       
  1019 library.  If this is what you want to do, use the GNU Lesser General
       
  1020 Public License instead of this License.

  1024                    GNU LESSER GENERAL PUBLIC LICENSE
       
  1025                        Version 3, 29 June 2007
       
  1026 
       
  1027  Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
       
  1028  Everyone is permitted to copy and distribute verbatim copies
       
  1029  of this license document, but changing it is not allowed.
       
  1030 
       
  1031 
       
  1032   This version of the GNU Lesser General Public License incorporates
       
  1033 the terms and conditions of version 3 of the GNU General Public
       
  1034 License, supplemented by the additional permissions listed below.
       
  1035 
       
  1036   0. Additional Definitions.
       
  1037 
       
  1038   As used herein, "this License" refers to version 3 of the GNU Lesser
       
  1039 General Public License, and the "GNU GPL" refers to version 3 of the GNU
       
  1040 General Public License.
       
  1041 
       
  1042   "The Library" refers to a covered work governed by this License,
       
  1043 other than an Application or a Combined Work as defined below.
       
  1044 
       
  1045   An "Application" is any work that makes use of an interface provided
       
  1046 by the Library, but which is not otherwise based on the Library.
       
  1047 Defining a subclass of a class defined by the Library is deemed a mode
       
  1048 of using an interface provided by the Library.
       
  1049 
       
  1050   A "Combined Work" is a work produced by combining or linking an
       
  1051 Application with the Library.  The particular version of the Library
       
  1052 with which the Combined Work was made is also called the "Linked
       
  1053 Version".
       
  1054 
       
  1055   The "Minimal Corresponding Source" for a Combined Work means the
       
  1056 Corresponding Source for the Combined Work, excluding any source code
       
  1057 for portions of the Combined Work that, considered in isolation, are
       
  1058 based on the Application, and not on the Linked Version.
       
  1059 
       
  1060   The "Corresponding Application Code" for a Combined Work means the
       
  1061 object code and/or source code for the Application, including any data
       
  1062 and utility programs needed for reproducing the Combined Work from the
       
  1063 Application, but excluding the System Libraries of the Combined Work.
       
  1064 
       
  1065   1. Exception to Section 3 of the GNU GPL.
       
  1066 
       
  1067   You may convey a covered work under sections 3 and 4 of this License
       
  1068 without being bound by section 3 of the GNU GPL.
       
  1069 
       
  1070   2. Conveying Modified Versions.
       
  1071 
       
  1072   If you modify a copy of the Library, and, in your modifications, a
       
  1073 facility refers to a function or data to be supplied by an Application
       
  1074 that uses the facility (other than as an argument passed when the
       
  1075 facility is invoked), then you may convey a copy of the modified
       
  1076 version:
       
  1077 
       
  1078    a) under this License, provided that you make a good faith effort to
       
  1079    ensure that, in the event an Application does not supply the
       
  1080    function or data, the facility still operates, and performs
       
  1081    whatever part of its purpose remains meaningful, or
       
  1082 
       
  1083    b) under the GNU GPL, with none of the additional permissions of
       
  1084    this License applicable to that copy.
       
  1085 
       
  1086   3. Object Code Incorporating Material from Library Header Files.
       
  1087 
       
  1088   The object code form of an Application may incorporate material from
       
  1089 a header file that is part of the Library.  You may convey such object
       
  1090 code under terms of your choice, provided that, if the incorporated
       
  1091 material is not limited to numerical parameters, data structure
       
  1092 layouts and accessors, or small macros, inline functions and templates
       
  1093 (ten or fewer lines in length), you do both of the following:
       
  1094 
       
  1095    a) Give prominent notice with each copy of the object code that the
       
  1096    Library is used in it and that the Library and its use are
       
  1097    covered by this License.
       
  1098 
       
  1099    b) Accompany the object code with a copy of the GNU GPL and this license
       
  1100    document.
       
  1101 
       
  1102   4. Combined Works.
       
  1103 
       
  1104   You may convey a Combined Work under terms of your choice that,
       
  1105 taken together, effectively do not restrict modification of the
       
  1106 portions of the Library contained in the Combined Work and reverse
       
  1107 engineering for debugging such modifications, if you also do each of
       
  1108 the following:
       
  1109 
       
  1110    a) Give prominent notice with each copy of the Combined Work that
       
  1111    the Library is used in it and that the Library and its use are
       
  1112    covered by this License.
       
  1113 
       
  1114    b) Accompany the Combined Work with a copy of the GNU GPL and this license
       
  1115    document.
       
  1116 
       
  1117    c) For a Combined Work that displays copyright notices during
       
  1118    execution, include the copyright notice for the Library among
       
  1119    these notices, as well as a reference directing the user to the
       
  1120    copies of the GNU GPL and this license document.
       
  1121 
       
  1122    d) Do one of the following:
       
  1123 
       
  1124        0) Convey the Minimal Corresponding Source under the terms of this
       
  1125        License, and the Corresponding Application Code in a form
       
  1126        suitable for, and under terms that permit, the user to
       
  1127        recombine or relink the Application with a modified version of
       
  1128        the Linked Version to produce a modified Combined Work, in the
       
  1129        manner specified by section 6 of the GNU GPL for conveying
       
  1130        Corresponding Source.
       
  1131 
       
  1132        1) Use a suitable shared library mechanism for linking with the
       
  1133        Library.  A suitable mechanism is one that (a) uses at run time
       
  1134        a copy of the Library already present on the user's computer
       
  1135        system, and (b) will operate properly with a modified version
       
  1136        of the Library that is interface-compatible with the Linked
       
  1137        Version.
       
  1138 
       
  1139    e) Provide Installation Information, but only if you would otherwise
       
  1140    be required to provide such information under section 6 of the
       
  1141    GNU GPL, and only to the extent that such information is
       
  1142    necessary to install and execute a modified version of the
       
  1143    Combined Work produced by recombining or relinking the
       
  1144    Application with a modified version of the Linked Version. (If
       
  1145    you use option 4d0, the Installation Information must accompany
       
  1146    the Minimal Corresponding Source and Corresponding Application
       
  1147    Code. If you use option 4d1, you must provide the Installation
       
  1148    Information in the manner specified by section 6 of the GNU GPL
       
  1149    for conveying Corresponding Source.)
       
  1150 
       
  1151   5. Combined Libraries.
       
  1152 
       
  1153   You may place library facilities that are a work based on the
       
  1154 Library side by side in a single library together with other library
       
  1155 facilities that are not Applications and are not covered by this
       
  1156 License, and convey such a combined library under terms of your
       
  1157 choice, if you do both of the following:
       
  1158 
       
  1159    a) Accompany the combined library with a copy of the same work based
       
  1160    on the Library, uncombined with any other library facilities,
       
  1161    conveyed under the terms of this License.
       
  1162 
       
  1163    b) Give prominent notice with the combined library that part of it
       
  1164    is a work based on the Library, and explaining where to find the
       
  1165    accompanying uncombined form of the same work.
       
  1166 
       
  1167   6. Revised Versions of the GNU Lesser General Public License.
       
  1168 
       
  1169   The Free Software Foundation may publish revised and/or new versions
       
  1170 of the GNU Lesser General Public License from time to time. Such new
       
  1171 versions will be similar in spirit to the present version, but may
       
  1172 differ in detail to address new problems or concerns.
       
  1173 
       
  1174   Each version is given a distinguishing version number. If the
       
  1175 Library as you received it specifies that a certain numbered version
       
  1176 of the GNU Lesser General Public License "or any later version"
       
  1177 applies to it, you have the option of following the terms and
       
  1178 conditions either of that published version or of any later version
       
  1179 published by the Free Software Foundation. If the Library as you
       
  1180 received it does not specify a version number of the GNU Lesser
       
  1181 General Public License, you may choose any version of the GNU Lesser
       
  1182 General Public License ever published by the Free Software Foundation.
       
  1183 
       
  1184   If the Library as you received it specifies that a proxy can decide
       
  1185 whether future versions of the GNU Lesser General Public License shall
       
  1186 apply, that proxy's public statement of acceptance of any version is
       
  1187 permanent authorization for you to choose that version for the
       
  1188 Library.

  1200 [This is the first released version of the Lesser GPL.  It also counts
       
  1201  as the successor of the GNU Library Public License, version 2, hence
       
  1202  the version number 2.1.]
       
  1203 
       
  1204                             Preamble
       
  1205 
       
  1206   The licenses for most software are designed to take away your
       
  1207 freedom to share and change it.  By contrast, the GNU General Public
       
  1208 Licenses are intended to guarantee your freedom to share and change
       
  1209 free software--to make sure the software is free for all its users.
       
  1210 
       
  1211   This license, the Lesser General Public License, applies to some
       
  1212 specially designated software packages--typically libraries--of the
       
  1213 Free Software Foundation and other authors who decide to use it.  You
       
  1214 can use it too, but we suggest you first think carefully about whether
       
  1215 this license or the ordinary General Public License is the better
       
  1216 strategy to use in any particular case, based on the explanations below.
       
  1217 
       
  1218   When we speak of free software, we are referring to freedom of use,
       
  1219 not price.  Our General Public Licenses are designed to make sure that
       
  1220 you have the freedom to distribute copies of free software (and charge
       
  1221 for this service if you wish); that you receive source code or can get
       
  1222 it if you want it; that you can change the software and use pieces of
       
  1223 it in new free programs; and that you are informed that you can do
       
  1224 these things.
       
  1225 
       
  1226   To protect your rights, we need to make restrictions that forbid
       
  1227 distributors to deny you these rights or to ask you to surrender these
       
  1228 rights.  These restrictions translate to certain responsibilities for
       
  1229 you if you distribute copies of the library or if you modify it.
       
  1230 
       
  1231   For example, if you distribute copies of the library, whether gratis
       
  1232 or for a fee, you must give the recipients all the rights that we gave
       
  1233 you.  You must make sure that they, too, receive or can get the source
       
  1234 code.  If you link other code with the library, you must provide
       
  1235 complete object files to the recipients, so that they can relink them
       
  1236 with the library after making changes to the library and recompiling
       
  1237 it.  And you must show them these terms so they know their rights.
       
  1238 
       
  1239   We protect your rights with a two-step method: (1) we copyright the
       
  1240 library, and (2) we offer you this license, which gives you legal
       
  1241 permission to copy, distribute and/or modify the library.
       
  1242 
       
  1243   To protect each distributor, we want to make it very clear that
       
  1244 there is no warranty for the free library.  Also, if the library is
       
  1245 modified by someone else and passed on, the recipients should know
       
  1246 that what they have is not the original version, so that the original
       
  1247 author's reputation will not be affected by problems that might be
       
  1248 introduced by others.
       
  1249 
       
  1250   Finally, software patents pose a constant threat to the existence of
       
  1251 any free program.  We wish to make sure that a company cannot
       
  1252 effectively restrict the users of a free program by obtaining a
       
  1253 restrictive license from a patent holder.  Therefore, we insist that
       
  1254 any patent license obtained for a version of the library must be
       
  1255 consistent with the full freedom of use specified in this license.
       
  1256 
       
  1257   Most GNU software, including some libraries, is covered by the
       
  1258 ordinary GNU General Public License.  This license, the GNU Lesser
       
  1259 General Public License, applies to certain designated libraries, and
       
  1260 is quite different from the ordinary General Public License.  We use
       
  1261 this license for certain libraries in order to permit linking those
       
  1262 libraries into non-free programs.
       
  1263 
       
  1264   When a program is linked with a library, whether statically or using
       
  1265 a shared library, the combination of the two is legally speaking a
       
  1266 combined work, a derivative of the original library.  The ordinary
       
  1267 General Public License therefore permits such linking only if the
       
  1268 entire combination fits its criteria of freedom.  The Lesser General
       
  1269 Public License permits more lax criteria for linking other code with
       
  1270 the library.
       
  1271 
       
  1272   We call this license the "Lesser" General Public License because it
       
  1273 does Less to protect the user's freedom than the ordinary General
       
  1274 Public License.  It also provides other free software developers Less
       
  1275 of an advantage over competing non-free programs.  These disadvantages
       
  1276 are the reason we use the ordinary General Public License for many
       
  1277 libraries.  However, the Lesser license provides advantages in certain
       
  1278 special circumstances.
       
  1279 
       
  1280   For example, on rare occasions, there may be a special need to
       
  1281 encourage the widest possible use of a certain library, so that it becomes
       
  1282 a de-facto standard.  To achieve this, non-free programs must be
       
  1283 allowed to use the library.  A more frequent case is that a free
       
  1284 library does the same job as widely used non-free libraries.  In this
       
  1285 case, there is little to gain by limiting the free library to free
       
  1286 software only, so we use the Lesser General Public License.
       
  1287 
       
  1288   In other cases, permission to use a particular library in non-free
       
  1289 programs enables a greater number of people to use a large body of
       
  1290 free software.  For example, permission to use the GNU C Library in
       
  1291 non-free programs enables many more people to use the whole GNU
       
  1292 operating system, as well as its variant, the GNU/Linux operating
       
  1293 system.
       
  1294 
       
  1295   Although the Lesser General Public License is Less protective of the
       
  1296 users' freedom, it does ensure that the user of a program that is
       
  1297 linked with the Library has the freedom and the wherewithal to run
       
  1298 that program using a modified version of the Library.
       
  1299 
       
  1300   The precise terms and conditions for copying, distribution and
       
  1301 modification follow.  Pay close attention to the difference between a
       
  1302 "work based on the library" and a "work that uses the library".  The
       
  1303 former contains code derived from the library, whereas the latter must
       
  1304 be combined with the library in order to run.

  1306                   GNU LESSER GENERAL PUBLIC LICENSE
       
  1307    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
       
  1308 
       
  1309   0. This License Agreement applies to any software library or other
       
  1310 program which contains a notice placed by the copyright holder or
       
  1311 other authorized party saying it may be distributed under the terms of
       
  1312 this Lesser General Public License (also called "this License").
       
  1313 Each licensee is addressed as "you".
       
  1314 
       
  1315   A "library" means a collection of software functions and/or data
       
  1316 prepared so as to be conveniently linked with application programs
       
  1317 (which use some of those functions and data) to form executables.
       
  1318 
       
  1319   The "Library", below, refers to any such software library or work
       
  1320 which has been distributed under these terms.  A "work based on the
       
  1321 Library" means either the Library or any derivative work under
       
  1322 copyright law: that is to say, a work containing the Library or a
       
  1323 portion of it, either verbatim or with modifications and/or translated
       
  1324 straightforwardly into another language.  (Hereinafter, translation is
       
  1325 included without limitation in the term "modification".)
       
  1326 
       
  1327   "Source code" for a work means the preferred form of the work for
       
  1328 making modifications to it.  For a library, complete source code means
       
  1329 all the source code for all modules it contains, plus any associated
       
  1330 interface definition files, plus the scripts used to control compilation
       
  1331 and installation of the library.
       
  1332 
       
  1333   Activities other than copying, distribution and modification are not
       
  1334 covered by this License; they are outside its scope.  The act of
       
  1335 running a program using the Library is not restricted, and output from
       
  1336 such a program is covered only if its contents constitute a work based
       
  1337 on the Library (independent of the use of the Library in a tool for
       
  1338 writing it).  Whether that is true depends on what the Library does
       
  1339 and what the program that uses the Library does.
       
  1340 
       
  1341   1. You may copy and distribute verbatim copies of the Library's
       
  1342 complete source code as you receive it, in any medium, provided that
       
  1343 you conspicuously and appropriately publish on each copy an
       
  1344 appropriate copyright notice and disclaimer of warranty; keep intact
       
  1345 all the notices that refer to this License and to the absence of any
       
  1346 warranty; and distribute a copy of this License along with the
       
  1347 Library.
       
  1348 
       
  1349   You may charge a fee for the physical act of transferring a copy,
       
  1350 and you may at your option offer warranty protection in exchange for a
       
  1351 fee.
       
  1352 
       
  1353   2. You may modify your copy or copies of the Library or any portion
       
  1354 of it, thus forming a work based on the Library, and copy and
       
  1355 distribute such modifications or work under the terms of Section 1
       
  1356 above, provided that you also meet all of these conditions:
       
  1357 
       
  1358     a) The modified work must itself be a software library.
       
  1359 
       
  1360     b) You must cause the files modified to carry prominent notices
       
  1361     stating that you changed the files and the date of any change.
       
  1362 
       
  1363     c) You must cause the whole of the work to be licensed at no
       
  1364     charge to all third parties under the terms of this License.
       
  1365 
       
  1366     d) If a facility in the modified Library refers to a function or a
       
  1367     table of data to be supplied by an application program that uses
       
  1368     the facility, other than as an argument passed when the facility
       
  1369     is invoked, then you must make a good faith effort to ensure that,
       
  1370     in the event an application does not supply such function or
       
  1371     table, the facility still operates, and performs whatever part of
       
  1372     its purpose remains meaningful.
       
  1373 
       
  1374     (For example, a function in a library to compute square roots has
       
  1375     a purpose that is entirely well-defined independent of the
       
  1376     application.  Therefore, Subsection 2d requires that any
       
  1377     application-supplied function or table used by this function must
       
  1378     be optional: if the application does not supply it, the square
       
  1379     root function must still compute square roots.)
       
  1380 
       
  1381 These requirements apply to the modified work as a whole.  If
       
  1382 identifiable sections of that work are not derived from the Library,
       
  1383 and can be reasonably considered independent and separate works in
       
  1384 themselves, then this License, and its terms, do not apply to those
       
  1385 sections when you distribute them as separate works.  But when you
       
  1386 distribute the same sections as part of a whole which is a work based
       
  1387 on the Library, the distribution of the whole must be on the terms of
       
  1388 this License, whose permissions for other licensees extend to the
       
  1389 entire whole, and thus to each and every part regardless of who wrote
       
  1390 it.
       
  1391 
       
  1392 Thus, it is not the intent of this section to claim rights or contest
       
  1393 your rights to work written entirely by you; rather, the intent is to
       
  1394 exercise the right to control the distribution of derivative or
       
  1395 collective works based on the Library.
       
  1396 
       
  1397 In addition, mere aggregation of another work not based on the Library
       
  1398 with the Library (or with a work based on the Library) on a volume of
       
  1399 a storage or distribution medium does not bring the other work under
       
  1400 the scope of this License.
       
  1401 
       
  1402   3. You may opt to apply the terms of the ordinary GNU General Public
       
  1403 License instead of this License to a given copy of the Library.  To do
       
  1404 this, you must alter all the notices that refer to this License, so
       
  1405 that they refer to the ordinary GNU General Public License, version 2,
       
  1406 instead of to this License.  (If a newer version than version 2 of the
       
  1407 ordinary GNU General Public License has appeared, then you can specify
       
  1408 that version instead if you wish.)  Do not make any other change in
       
  1409 these notices.
       
  1410 
       
  1411   Once this change is made in a given copy, it is irreversible for
       
  1412 that copy, so the ordinary GNU General Public License applies to all
       
  1413 subsequent copies and derivative works made from that copy.
       
  1414 
       
  1415   This option is useful when you wish to copy part of the code of
       
  1416 the Library into a program that is not a library.
       
  1417 
       
  1418   4. You may copy and distribute the Library (or a portion or
       
  1419 derivative of it, under Section 2) in object code or executable form
       
  1420 under the terms of Sections 1 and 2 above provided that you accompany
       
  1421 it with the complete corresponding machine-readable source code, which
       
  1422 must be distributed under the terms of Sections 1 and 2 above on a
       
  1423 medium customarily used for software interchange.
       
  1424 
       
  1425   If distribution of object code is made by offering access to copy
       
  1426 from a designated place, then offering equivalent access to copy the
       
  1427 source code from the same place satisfies the requirement to
       
  1428 distribute the source code, even though third parties are not
       
  1429 compelled to copy the source along with the object code.
       
  1430 
       
  1431   5. A program that contains no derivative of any portion of the
       
  1432 Library, but is designed to work with the Library by being compiled or
       
  1433 linked with it, is called a "work that uses the Library".  Such a
       
  1434 work, in isolation, is not a derivative work of the Library, and
       
  1435 therefore falls outside the scope of this License.
       
  1436 
       
  1437   However, linking a "work that uses the Library" with the Library
       
  1438 creates an executable that is a derivative of the Library (because it
       
  1439 contains portions of the Library), rather than a "work that uses the
       
  1440 library".  The executable is therefore covered by this License.
       
  1441 Section 6 states terms for distribution of such executables.
       
  1442 
       
  1443   When a "work that uses the Library" uses material from a header file
       
  1444 that is part of the Library, the object code for the work may be a
       
  1445 derivative work of the Library even though the source code is not.
       
  1446 Whether this is true is especially significant if the work can be
       
  1447 linked without the Library, or if the work is itself a library.  The
       
  1448 threshold for this to be true is not precisely defined by law.
       
  1449 
       
  1450   If such an object file uses only numerical parameters, data
       
  1451 structure layouts and accessors, and small macros and small inline
       
  1452 functions (ten lines or less in length), then the use of the object
       
  1453 file is unrestricted, regardless of whether it is legally a derivative
       
  1454 work.  (Executables containing this object code plus portions of the
       
  1455 Library will still fall under Section 6.)
       
  1456 
       
  1457   Otherwise, if the work is a derivative of the Library, you may
       
  1458 distribute the object code for the work under the terms of Section 6.
       
  1459 Any executables containing that work also fall under Section 6,
       
  1460 whether or not they are linked directly with the Library itself.
       
  1461 
       
  1462   6. As an exception to the Sections above, you may also combine or
       
  1463 link a "work that uses the Library" with the Library to produce a
       
  1464 work containing portions of the Library, and distribute that work
       
  1465 under terms of your choice, provided that the terms permit
       
  1466 modification of the work for the customer's own use and reverse
       
  1467 engineering for debugging such modifications.
       
  1468 
       
  1469   You must give prominent notice with each copy of the work that the
       
  1470 Library is used in it and that the Library and its use are covered by
       
  1471 this License.  You must supply a copy of this License.  If the work
       
  1472 during execution displays copyright notices, you must include the
       
  1473 copyright notice for the Library among them, as well as a reference
       
  1474 directing the user to the copy of this License.  Also, you must do one
       
  1475 of these things:
       
  1476 
       
  1477     a) Accompany the work with the complete corresponding
       
  1478     machine-readable source code for the Library including whatever
       
  1479     changes were used in the work (which must be distributed under
       
  1480     Sections 1 and 2 above); and, if the work is an executable linked
       
  1481     with the Library, with the complete machine-readable "work that
       
  1482     uses the Library", as object code and/or source code, so that the
       
  1483     user can modify the Library and then relink to produce a modified
       
  1484     executable containing the modified Library.  (It is understood
       
  1485     that the user who changes the contents of definitions files in the
       
  1486     Library will not necessarily be able to recompile the application
       
  1487     to use the modified definitions.)
       
  1488 
       
  1489     b) Use a suitable shared library mechanism for linking with the
       
  1490     Library.  A suitable mechanism is one that (1) uses at run time a
       
  1491     copy of the library already present on the user's computer system,
       
  1492     rather than copying library functions into the executable, and (2)
       
  1493     will operate properly with a modified version of the library, if
       
  1494     the user installs one, as long as the modified version is
       
  1495     interface-compatible with the version that the work was made with.
       
  1496 
       
  1497     c) Accompany the work with a written offer, valid for at
       
  1498     least three years, to give the same user the materials
       
  1499     specified in Subsection 6a, above, for a charge no more
       
  1500     than the cost of performing this distribution.
       
  1501 
       
  1502     d) If distribution of the work is made by offering access to copy
       
  1503     from a designated place, offer equivalent access to copy the above
       
  1504     specified materials from the same place.
       
  1505 
       
  1506     e) Verify that the user has already received a copy of these
       
  1507     materials or that you have already sent this user a copy.
       
  1508 
       
  1509   For an executable, the required form of the "work that uses the
       
  1510 Library" must include any data and utility programs needed for
       
  1511 reproducing the executable from it.  However, as a special exception,
       
  1512 the materials to be distributed need not include anything that is
       
  1513 normally distributed (in either source or binary form) with the major
       
  1514 components (compiler, kernel, and so on) of the operating system on
       
  1515 which the executable runs, unless that component itself accompanies
       
  1516 the executable.
       
  1517 
       
  1518   It may happen that this requirement contradicts the license
       
  1519 restrictions of other proprietary libraries that do not normally
       
  1520 accompany the operating system.  Such a contradiction means you cannot
       
  1521 use both them and the Library together in an executable that you
       
  1522 distribute.
       
  1523 
       
  1524   7. You may place library facilities that are a work based on the
       
  1525 Library side-by-side in a single library together with other library
       
  1526 facilities not covered by this License, and distribute such a combined
       
  1527 library, provided that the separate distribution of the work based on
       
  1528 the Library and of the other library facilities is otherwise
       
  1529 permitted, and provided that you do these two things:
       
  1530 
       
  1531     a) Accompany the combined library with a copy of the same work
       
  1532     based on the Library, uncombined with any other library
       
  1533     facilities.  This must be distributed under the terms of the
       
  1534     Sections above.
       
  1535 
       
  1536     b) Give prominent notice with the combined library of the fact
       
  1537     that part of it is a work based on the Library, and explaining
       
  1538     where to find the accompanying uncombined form of the same work.
       
  1539 
       
  1540   8. You may not copy, modify, sublicense, link with, or distribute
       
  1541 the Library except as expressly provided under this License.  Any
       
  1542 attempt otherwise to copy, modify, sublicense, link with, or
       
  1543 distribute the Library is void, and will automatically terminate your
       
  1544 rights under this License.  However, parties who have received copies,
       
  1545 or rights, from you under this License will not have their licenses
       
  1546 terminated so long as such parties remain in full compliance.
       
  1547 
       
  1548   9. You are not required to accept this License, since you have not
       
  1549 signed it.  However, nothing else grants you permission to modify or
       
  1550 distribute the Library or its derivative works.  These actions are
       
  1551 prohibited by law if you do not accept this License.  Therefore, by
       
  1552 modifying or distributing the Library (or any work based on the
       
  1553 Library), you indicate your acceptance of this License to do so, and
       
  1554 all its terms and conditions for copying, distributing or modifying
       
  1555 the Library or works based on it.
       
  1556 
       
  1557   10. Each time you redistribute the Library (or any work based on the
       
  1558 Library), the recipient automatically receives a license from the
       
  1559 original licensor to copy, distribute, link with or modify the Library
       
  1560 subject to these terms and conditions.  You may not impose any further
       
  1561 restrictions on the recipients' exercise of the rights granted herein.
       
  1562 You are not responsible for enforcing compliance by third parties with
       
  1563 this License.
       
  1564 
       
  1565   11. If, as a consequence of a court judgment or allegation of patent
       
  1566 infringement or for any other reason (not limited to patent issues),
       
  1567 conditions are imposed on you (whether by court order, agreement or
       
  1568 otherwise) that contradict the conditions of this License, they do not
       
  1569 excuse you from the conditions of this License.  If you cannot
       
  1570 distribute so as to satisfy simultaneously your obligations under this
       
  1571 License and any other pertinent obligations, then as a consequence you
       
  1572 may not distribute the Library at all.  For example, if a patent
       
  1573 license would not permit royalty-free redistribution of the Library by
       
  1574 all those who receive copies directly or indirectly through you, then
       
  1575 the only way you could satisfy both it and this License would be to
       
  1576 refrain entirely from distribution of the Library.
       
  1577 
       
  1578 If any portion of this section is held invalid or unenforceable under any
       
  1579 particular circumstance, the balance of the section is intended to apply,
       
  1580 and the section as a whole is intended to apply in other circumstances.
       
  1581 
       
  1582 It is not the purpose of this section to induce you to infringe any
       
  1583 patents or other property right claims or to contest validity of any
       
  1584 such claims; this section has the sole purpose of protecting the
       
  1585 integrity of the free software distribution system which is
       
  1586 implemented by public license practices.  Many people have made
       
  1587 generous contributions to the wide range of software distributed
       
  1588 through that system in reliance on consistent application of that
       
  1589 system; it is up to the author/donor to decide if he or she is willing
       
  1590 to distribute software through any other system and a licensee cannot
       
  1591 impose that choice.
       
  1592 
       
  1593 This section is intended to make thoroughly clear what is believed to
       
  1594 be a consequence of the rest of this License.
       
  1595 
       
  1596   12. If the distribution and/or use of the Library is restricted in
       
  1597 certain countries either by patents or by copyrighted interfaces, the
       
  1598 original copyright holder who places the Library under this License may add
       
  1599 an explicit geographical distribution limitation excluding those countries,
       
  1600 so that distribution is permitted only in or among countries not thus
       
  1601 excluded.  In such case, this License incorporates the limitation as if
       
  1602 written in the body of this License.
       
  1603 
       
  1604   13. The Free Software Foundation may publish revised and/or new
       
  1605 versions of the Lesser General Public License from time to time.
       
  1606 Such new versions will be similar in spirit to the present version,
       
  1607 but may differ in detail to address new problems or concerns.
       
  1608 
       
  1609 Each version is given a distinguishing version number.  If the Library
       
  1610 specifies a version number of this License which applies to it and
       
  1611 "any later version", you have the option of following the terms and
       
  1612 conditions either of that version or of any later version published by
       
  1613 the Free Software Foundation.  If the Library does not specify a
       
  1614 license version number, you may choose any version ever published by
       
  1615 the Free Software Foundation.
       
  1616 
       
  1617   14. If you wish to incorporate parts of the Library into other free
       
  1618 programs whose distribution conditions are incompatible with these,
       
  1619 write to the author to ask for permission.  For software which is
       
  1620 copyrighted by the Free Software Foundation, write to the Free
       
  1621 Software Foundation; we sometimes make exceptions for this.  Our
       
  1622 decision will be guided by the two goals of preserving the free status
       
  1623 of all derivatives of our free software and of promoting the sharing
       
  1624 and reuse of software generally.
       
  1625 
       
  1626                             NO WARRANTY
       
  1627 
       
  1628   15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
       
  1629 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
       
  1630 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
       
  1631 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
       
  1632 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
       
  1633 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
       
  1634 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
       
  1635 LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
       
  1636 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
       
  1637 
       
  1638   16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
       
  1639 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
       
  1640 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
       
  1641 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
       
  1642 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
       
  1643 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
       
  1644 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
       
  1645 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
       
  1646 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
       
  1647 DAMAGES.
       
  1648 
       
  1649                      END OF TERMS AND CONDITIONS
       
  1650 
       
  1651            How to Apply These Terms to Your New Libraries
       
  1652 
       
  1653   If you develop a new library, and you want it to be of the greatest
       
  1654 possible use to the public, we recommend making it free software that
       
  1655 everyone can redistribute and change.  You can do so by permitting
       
  1656 redistribution under these terms (or, alternatively, under the terms of the
       
  1657 ordinary General Public License).
       
  1658 
       
  1659   To apply these terms, attach the following notices to the library.  It is
       
  1660 safest to attach them to the start of each source file to most effectively
       
  1661 convey the exclusion of warranty; and each file should have at least the
       
  1662 "copyright" line and a pointer to where the full notice is found.

  1666 
       
  1667     This library is free software; you can redistribute it and/or
       
  1668     modify it under the terms of the GNU Lesser General Public
       
  1669     License as published by the Free Software Foundation; either
       
  1670     version 2.1 of the License, or (at your option) any later version.
       
  1671 
       
  1672     This library is distributed in the hope that it will be useful,
       
  1673     but WITHOUT ANY WARRANTY; without even the implied warranty of

  1676 
       
  1677     You should have received a copy of the GNU Lesser General Public
       
  1678     License along with this library; if not, write to the Free Software

  1681 Also add information on how to contact you by electronic and paper mail.
       
  1682 
       
  1683 You should also get your employer (if you work as a programmer) or your
       
  1684 school, if any, to sign a "copyright disclaimer" for the library, if
       
  1685 necessary.  Here is a sample; alter the names:

  1698 GCC RUNTIME LIBRARY EXCEPTION
       
  1699 
       
  1700 Version 3.1, 31 March 2009
       
  1701 
       
  1702 Copyright © 2009 Free Software Foundation, Inc. <http://fsf.org/>
       
  1703 
       
  1704 Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
       
  1705 
       
  1706 This GCC Runtime Library Exception ("Exception") is an additional permission under section 7 of the GNU General Public License, version 3 ("GPLv3"). It applies to a given file (the "Runtime Library") that bears a notice placed by the copyright holder of the file stating that the file is governed by GPLv3 along with this Exception.
       
  1707 
       
  1708 When you use GCC to compile a program, GCC may combine portions of certain GCC header files and runtime libraries with the compiled program. The purpose of this Exception is to allow compilation of non-GPL (including proprietary) programs to use, in this way, the header files and runtime libraries covered by this Exception.
       
  1709 0. Definitions.
       
  1710 
       
  1711 A file is an "Independent Module" if it either requires the Runtime Library for execution after a Compilation Process, or makes use of an interface provided by the Runtime Library, but is not otherwise based on the Runtime Library.
       
  1712 
       
  1713 "GCC" means a version of the GNU Compiler Collection, with or without modifications, governed by version 3 (or a specified later version) of the GNU General Public License (GPL) with the option of using any subsequent versions published by the FSF.
       
  1714 
       
  1715 "GPL-compatible Software" is software whose conditions of propagation, modification and use would permit combination with GCC in accord with the license of GCC.
       
  1716 
       
  1717 "Target Code" refers to output from any compiler for a real or virtual target processor architecture, in executable form or suitable for input to an assembler, loader, linker and/or execution phase. Notwithstanding that, Target Code does not include data in any format that is used as a compiler intermediate representation, or used for producing a compiler intermediate representation.
       
  1718 
       
  1719 The "Compilation Process" transforms code entirely represented in non-intermediate languages designed for human-written code, and/or in Java Virtual Machine byte code, into Target Code. Thus, for example, use of source code generators and preprocessors need not be considered part of the Compilation Process, since the Compilation Process can be understood as starting with the output of the generators or preprocessors.
       
  1720 
       
  1721 A Compilation Process is "Eligible" if it is done using GCC, alone or with other GPL-compatible software, or if it is done without using any work based on GCC. For example, using non-GPL-compatible Software to optimize any GCC intermediate representations would not qualify as an Eligible Compilation Process.
       
  1722 1. Grant of Additional Permission.
       
  1723 
       
  1724 You have permission to propagate a work of Target Code formed by combining the Runtime Library with Independent Modules, even if such propagation would otherwise violate the terms of GPLv3, provided that all Target Code was generated by Eligible Compilation Processes. You may then convey such a combination under terms of your choice, consistent with the licensing of the Independent Modules.
       
  1725 2. No Weakening of GCC Copyleft.
       
  1726 
       
  1727 The availability of this Exception does not imply any general presumption that third-party software is unaffected by the copyleft requirements of the license of GCC.

  1738  Everyone is permitted to copy and distribute verbatim copies

  1740 
       
  1741 0. PREAMBLE
       
  1742 
       
  1743 The purpose of this License is to make a manual, textbook, or other
       
  1744 functional and useful document "free" in the sense of freedom: to
       
  1745 assure everyone the effective freedom to copy and redistribute it,
       
  1746 with or without modifying it, either commercially or noncommercially.
       
  1747 Secondarily, this License preserves for the author and publisher a way
       
  1748 to get credit for their work, while not being considered responsible
       
  1749 for modifications made by others.
       
  1750 
       
  1751 This License is a kind of "copyleft", which means that derivative
       
  1752 works of the document must themselves be free in the same sense.  It
       
  1753 complements the GNU General Public License, which is a copyleft
       
  1754 license designed for free software.
       
  1755 
       
  1756 We have designed this License in order to use it for manuals for free
       
  1757 software, because free software needs free documentation: a free
       
  1758 program should come with manuals providing the same freedoms that the
       
  1759 software does.  But this License is not limited to software manuals;
       
  1760 it can be used for any textual work, regardless of subject matter or
       
  1761 whether it is published as a printed book.  We recommend this License
       
  1762 principally for works whose purpose is instruction or reference.
       
  1763 
       
  1764 
       
  1765 1. APPLICABILITY AND DEFINITIONS
       
  1766 
       
  1767 This License applies to any manual or other work, in any medium, that
       
  1768 contains a notice placed by the copyright holder saying it can be
       
  1769 distributed under the terms of this License.  Such a notice grants a
       
  1770 world-wide, royalty-free license, unlimited in duration, to use that
       
  1771 work under the conditions stated herein.  The "Document", below,
       
  1772 refers to any such manual or work.  Any member of the public is a
       
  1773 licensee, and is addressed as "you".  You accept the license if you
       
  1774 copy, modify or distribute the work in a way requiring permission
       
  1775 under copyright law.
       
  1776 
       
  1777 A "Modified Version" of the Document means any work containing the
       
  1778 Document or a portion of it, either copied verbatim, or with
       
  1779 modifications and/or translated into another language.
       
  1780 
       
  1781 A "Secondary Section" is a named appendix or a front-matter section of
       
  1782 the Document that deals exclusively with the relationship of the
       
  1783 publishers or authors of the Document to the Document's overall
       
  1784 subject (or to related matters) and contains nothing that could fall
       
  1785 directly within that overall subject.  (Thus, if the Document is in
       
  1786 part a textbook of mathematics, a Secondary Section may not explain
       
  1787 any mathematics.)  The relationship could be a matter of historical
       
  1788 connection with the subject or with related matters, or of legal,
       
  1789 commercial, philosophical, ethical or political position regarding
       
  1790 them.
       
  1791 
       
  1792 The "Invariant Sections" are certain Secondary Sections whose titles
       
  1793 are designated, as being those of Invariant Sections, in the notice
       
  1794 that says that the Document is released under this License.  If a
       
  1795 section does not fit the above definition of Secondary then it is not
       
  1796 allowed to be designated as Invariant.  The Document may contain zero
       
  1797 Invariant Sections.  If the Document does not identify any Invariant
       
  1798 Sections then there are none.
       
  1799 
       
  1800 The "Cover Texts" are certain short passages of text that are listed,
       
  1801 as Front-Cover Texts or Back-Cover Texts, in the notice that says that
       
  1802 the Document is released under this License.  A Front-Cover Text may
       
  1803 be at most 5 words, and a Back-Cover Text may be at most 25 words.
       
  1804 
       
  1805 A "Transparent" copy of the Document means a machine-readable copy,
       
  1806 represented in a format whose specification is available to the
       
  1807 general public, that is suitable for revising the document
       
  1808 straightforwardly with generic text editors or (for images composed of
       
  1809 pixels) generic paint programs or (for drawings) some widely available
       
  1810 drawing editor, and that is suitable for input to text formatters or
       
  1811 for automatic translation to a variety of formats suitable for input
       
  1812 to text formatters.  A copy made in an otherwise Transparent file
       
  1813 format whose markup, or absence of markup, has been arranged to thwart
       
  1814 or discourage subsequent modification by readers is not Transparent.
       
  1815 An image format is not Transparent if used for any substantial amount
       
  1816 of text.  A copy that is not "Transparent" is called "Opaque".
       
  1817 
       
  1818 Examples of suitable formats for Transparent copies include plain
       
  1819 ASCII without markup, Texinfo input format, LaTeX input format, SGML
       
  1820 or XML using a publicly available DTD, and standard-conforming simple
       
  1821 HTML, PostScript or PDF designed for human modification.  Examples of
       
  1822 transparent image formats include PNG, XCF and JPG.  Opaque formats
       
  1823 include proprietary formats that can be read and edited only by
       
  1824 proprietary word processors, SGML or XML for which the DTD and/or
       
  1825 processing tools are not generally available, and the
       
  1826 machine-generated HTML, PostScript or PDF produced by some word
       
  1827 processors for output purposes only.
       
  1828 
       
  1829 The "Title Page" means, for a printed book, the title page itself,
       
  1830 plus such following pages as are needed to hold, legibly, the material
       
  1831 this License requires to appear in the title page.  For works in
       
  1832 formats which do not have any title page as such, "Title Page" means
       
  1833 the text near the most prominent appearance of the work's title,
       
  1834 preceding the beginning of the body of the text.
       
  1835 
       
  1836 The "publisher" means any person or entity that distributes copies of
       
  1837 the Document to the public.
       
  1838 
       
  1839 A section "Entitled XYZ" means a named subunit of the Document whose
       
  1840 title either is precisely XYZ or contains XYZ in parentheses following
       
  1841 text that translates XYZ in another language.  (Here XYZ stands for a
       
  1842 specific section name mentioned below, such as "Acknowledgements",
       
  1843 "Dedications", "Endorsements", or "History".)  To "Preserve the Title"
       
  1844 of such a section when you modify the Document means that it remains a
       
  1845 section "Entitled XYZ" according to this definition.
       
  1846 
       
  1847 The Document may include Warranty Disclaimers next to the notice which
       
  1848 states that this License applies to the Document.  These Warranty
       
  1849 Disclaimers are considered to be included by reference in this
       
  1850 License, but only as regards disclaiming warranties: any other
       
  1851 implication that these Warranty Disclaimers may have is void and has
       
  1852 no effect on the meaning of this License.
       
  1853 
       
  1854 2. VERBATIM COPYING
       
  1855 
       
  1856 You may copy and distribute the Document in any medium, either
       
  1857 commercially or noncommercially, provided that this License, the
       
  1858 copyright notices, and the license notice saying this License applies
       
  1859 to the Document are reproduced in all copies, and that you add no
       
  1860 other conditions whatsoever to those of this License.  You may not use
       
  1861 technical measures to obstruct or control the reading or further
       
  1862 copying of the copies you make or distribute.  However, you may accept
       
  1863 compensation in exchange for copies.  If you distribute a large enough
       
  1864 number of copies you must also follow the conditions in section 3.
       
  1865 
       
  1866 You may also lend copies, under the same conditions stated above, and
       
  1867 you may publicly display copies.
       
  1868 
       
  1869 
       
  1870 3. COPYING IN QUANTITY
       
  1871 
       
  1872 If you publish printed copies (or copies in media that commonly have
       
  1873 printed covers) of the Document, numbering more than 100, and the
       
  1874 Document's license notice requires Cover Texts, you must enclose the
       
  1875 copies in covers that carry, clearly and legibly, all these Cover
       
  1876 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
       
  1877 the back cover.  Both covers must also clearly and legibly identify
       
  1878 you as the publisher of these copies.  The front cover must present
       
  1879 the full title with all words of the title equally prominent and
       
  1880 visible.  You may add other material on the covers in addition.
       
  1881 Copying with changes limited to the covers, as long as they preserve
       
  1882 the title of the Document and satisfy these conditions, can be treated
       
  1883 as verbatim copying in other respects.
       
  1884 
       
  1885 If the required texts for either cover are too voluminous to fit
       
  1886 legibly, you should put the first ones listed (as many as fit
       
  1887 reasonably) on the actual cover, and continue the rest onto adjacent
       
  1888 pages.
       
  1889 
       
  1890 If you publish or distribute Opaque copies of the Document numbering
       
  1891 more than 100, you must either include a machine-readable Transparent
       
  1892 copy along with each Opaque copy, or state in or with each Opaque copy
       
  1893 a computer-network location from which the general network-using
       
  1894 public has access to download using public-standard network protocols
       
  1895 a complete Transparent copy of the Document, free of added material.
       
  1896 If you use the latter option, you must take reasonably prudent steps,
       
  1897 when you begin distribution of Opaque copies in quantity, to ensure
       
  1898 that this Transparent copy will remain thus accessible at the stated
       
  1899 location until at least one year after the last time you distribute an
       
  1900 Opaque copy (directly or through your agents or retailers) of that
       
  1901 edition to the public.
       
  1902 
       
  1903 It is requested, but not required, that you contact the authors of the
       
  1904 Document well before redistributing any large number of copies, to
       
  1905 give them a chance to provide you with an updated version of the
       
  1906 Document.
       
  1907 
       
  1908 
       
  1909 4. MODIFICATIONS
       
  1910 
       
  1911 You may copy and distribute a Modified Version of the Document under
       
  1912 the conditions of sections 2 and 3 above, provided that you release
       
  1913 the Modified Version under precisely this License, with the Modified
       
  1914 Version filling the role of the Document, thus licensing distribution
       
  1915 and modification of the Modified Version to whoever possesses a copy
       
  1916 of it.  In addition, you must do these things in the Modified Version:
       
  1917 
       
  1918 A. Use in the Title Page (and on the covers, if any) a title distinct
       
  1919    from that of the Document, and from those of previous versions
       
  1920    (which should, if there were any, be listed in the History section
       
  1921    of the Document).  You may use the same title as a previous version
       
  1922    if the original publisher of that version gives permission.
       
  1923 B. List on the Title Page, as authors, one or more persons or entities
       
  1924    responsible for authorship of the modifications in the Modified
       
  1925    Version, together with at least five of the principal authors of the
       
  1926    Document (all of its principal authors, if it has fewer than five),
       
  1927    unless they release you from this requirement.
       
  1928 C. State on the Title page the name of the publisher of the
       
  1929    Modified Version, as the publisher.
       
  1930 D. Preserve all the copyright notices of the Document.
       
  1931 E. Add an appropriate copyright notice for your modifications
       
  1932    adjacent to the other copyright notices.
       
  1933 F. Include, immediately after the copyright notices, a license notice
       
  1934    giving the public permission to use the Modified Version under the
       
  1935    terms of this License, in the form shown in the Addendum below.
       
  1936 G. Preserve in that license notice the full lists of Invariant Sections
       
  1937    and required Cover Texts given in the Document's license notice.
       
  1938 H. Include an unaltered copy of this License.
       
  1939 I. Preserve the section Entitled "History", Preserve its Title, and add
       
  1940    to it an item stating at least the title, year, new authors, and
       
  1941    publisher of the Modified Version as given on the Title Page.  If
       
  1942    there is no section Entitled "History" in the Document, create one
       
  1943    stating the title, year, authors, and publisher of the Document as
       
  1944    given on its Title Page, then add an item describing the Modified
       
  1945    Version as stated in the previous sentence.
       
  1946 J. Preserve the network location, if any, given in the Document for
       
  1947    public access to a Transparent copy of the Document, and likewise
       
  1948    the network locations given in the Document for previous versions
       
  1949    it was based on.  These may be placed in the "History" section.
       
  1950    You may omit a network location for a work that was published at
       
  1951    least four years before the Document itself, or if the original
       
  1952    publisher of the version it refers to gives permission.
       
  1953 K. For any section Entitled "Acknowledgements" or "Dedications",
       
  1954    Preserve the Title of the section, and preserve in the section all
       
  1955    the substance and tone of each of the contributor acknowledgements
       
  1956    and/or dedications given therein.
       
  1957 L. Preserve all the Invariant Sections of the Document,
       
  1958    unaltered in their text and in their titles.  Section numbers
       
  1959    or the equivalent are not considered part of the section titles.
       
  1960 M. Delete any section Entitled "Endorsements".  Such a section
       
  1961    may not be included in the Modified Version.
       
  1962 N. Do not retitle any existing section to be Entitled "Endorsements"
       
  1963    or to conflict in title with any Invariant Section.
       
  1964 O. Preserve any Warranty Disclaimers.
       
  1965 
       
  1966 If the Modified Version includes new front-matter sections or
       
  1967 appendices that qualify as Secondary Sections and contain no material
       
  1968 copied from the Document, you may at your option designate some or all
       
  1969 of these sections as invariant.  To do this, add their titles to the
       
  1970 list of Invariant Sections in the Modified Version's license notice.
       
  1971 These titles must be distinct from any other section titles.
       
  1972 
       
  1973 You may add a section Entitled "Endorsements", provided it contains
       
  1974 nothing but endorsements of your Modified Version by various
       
  1975 parties--for example, statements of peer review or that the text has
       
  1976 been approved by an organization as the authoritative definition of a
       
  1977 standard.
       
  1978 
       
  1979 You may add a passage of up to five words as a Front-Cover Text, and a
       
  1980 passage of up to 25 words as a Back-Cover Text, to the end of the list
       
  1981 of Cover Texts in the Modified Version.  Only one passage of
       
  1982 Front-Cover Text and one of Back-Cover Text may be added by (or
       
  1983 through arrangements made by) any one entity.  If the Document already
       
  1984 includes a cover text for the same cover, previously added by you or
       
  1985 by arrangement made by the same entity you are acting on behalf of,
       
  1986 you may not add another; but you may replace the old one, on explicit
       
  1987 permission from the previous publisher that added the old one.
       
  1988 
       
  1989 The author(s) and publisher(s) of the Document do not by this License
       
  1990 give permission to use their names for publicity for or to assert or
       
  1991 imply endorsement of any Modified Version.
       
  1992 
       
  1993 
       
  1994 5. COMBINING DOCUMENTS
       
  1995 
       
  1996 You may combine the Document with other documents released under this
       
  1997 License, under the terms defined in section 4 above for modified
       
  1998 versions, provided that you include in the combination all of the
       
  1999 Invariant Sections of all of the original documents, unmodified, and
       
  2000 list them all as Invariant Sections of your combined work in its
       
  2001 license notice, and that you preserve all their Warranty Disclaimers.
       
  2002 
       
  2003 The combined work need only contain one copy of this License, and
       
  2004 multiple identical Invariant Sections may be replaced with a single
       
  2005 copy.  If there are multiple Invariant Sections with the same name but
       
  2006 different contents, make the title of each such section unique by
       
  2007 adding at the end of it, in parentheses, the name of the original
       
  2008 author or publisher of that section if known, or else a unique number.
       
  2009 Make the same adjustment to the section titles in the list of
       
  2010 Invariant Sections in the license notice of the combined work.
       
  2011 
       
  2012 In the combination, you must combine any sections Entitled "History"
       
  2013 in the various original documents, forming one section Entitled
       
  2014 "History"; likewise combine any sections Entitled "Acknowledgements",
       
  2015 and any sections Entitled "Dedications".  You must delete all sections
       
  2016 Entitled "Endorsements".
       
  2017 
       
  2018 
       
  2019 6. COLLECTIONS OF DOCUMENTS
       
  2020 
       
  2021 You may make a collection consisting of the Document and other
       
  2022 documents released under this License, and replace the individual
       
  2023 copies of this License in the various documents with a single copy
       
  2024 that is included in the collection, provided that you follow the rules
       
  2025 of this License for verbatim copying of each of the documents in all
       
  2026 other respects.
       
  2027 
       
  2028 You may extract a single document from such a collection, and
       
  2029 distribute it individually under this License, provided you insert a
       
  2030 copy of this License into the extracted document, and follow this
       
  2031 License in all other respects regarding verbatim copying of that
       
  2032 document.
       
  2033 
       
  2034 
       
  2035 7. AGGREGATION WITH INDEPENDENT WORKS
       
  2036 
       
  2037 A compilation of the Document or its derivatives with other separate
       
  2038 and independent documents or works, in or on a volume of a storage or
       
  2039 distribution medium, is called an "aggregate" if the copyright
       
  2040 resulting from the compilation is not used to limit the legal rights
       
  2041 of the compilation's users beyond what the individual works permit.
       
  2042 When the Document is included in an aggregate, this License does not
       
  2043 apply to the other works in the aggregate which are not themselves
       
  2044 derivative works of the Document.
       
  2045 
       
  2046 If the Cover Text requirement of section 3 is applicable to these
       
  2047 copies of the Document, then if the Document is less than one half of
       
  2048 the entire aggregate, the Document's Cover Texts may be placed on
       
  2049 covers that bracket the Document within the aggregate, or the
       
  2050 electronic equivalent of covers if the Document is in electronic form.
       
  2051 Otherwise they must appear on printed covers that bracket the whole
       
  2052 aggregate.
       
  2053 
       
  2054 
       
  2055 8. TRANSLATION
       
  2056 
       
  2057 Translation is considered a kind of modification, so you may
       
  2058 distribute translations of the Document under the terms of section 4.
       
  2059 Replacing Invariant Sections with translations requires special
       
  2060 permission from their copyright holders, but you may include
       
  2061 translations of some or all Invariant Sections in addition to the
       
  2062 original versions of these Invariant Sections.  You may include a
       
  2063 translation of this License, and all the license notices in the
       
  2064 Document, and any Warranty Disclaimers, provided that you also include
       
  2065 the original English version of this License and the original versions
       
  2066 of those notices and disclaimers.  In case of a disagreement between
       
  2067 the translation and the original version of this License or a notice
       
  2068 or disclaimer, the original version will prevail.
       
  2069 
       
  2070 If a section in the Document is Entitled "Acknowledgements",
       
  2071 "Dedications", or "History", the requirement (section 4) to Preserve
       
  2072 its Title (section 1) will typically require changing the actual
       
  2073 title.

  2076 9. TERMINATION
       
  2077 
       
  2078 You may not copy, modify, sublicense, or distribute the Document
       
  2079 except as expressly provided under this License.  Any attempt
       
  2080 otherwise to copy, modify, sublicense, or distribute it is void, and
       
  2081 will automatically terminate your rights under this License.
       
  2082 
       
  2083 However, if you cease all violation of this License, then your license
       
  2084 from a particular copyright holder is reinstated (a) provisionally,
       
  2085 unless and until the copyright holder explicitly and finally
       
  2086 terminates your license, and (b) permanently, if the copyright holder
       
  2087 fails to notify you of the violation by some reasonable means prior to
       
  2088 60 days after the cessation.
       
  2089 
       
  2090 Moreover, your license from a particular copyright holder is
       
  2091 reinstated permanently if the copyright holder notifies you of the
       
  2092 violation by some reasonable means, this is the first time you have
       
  2093 received notice of violation of this License (for any work) from that
       
  2094 copyright holder, and you cure the violation prior to 30 days after
       
  2095 your receipt of the notice.
       
  2096 
       
  2097 Termination of your rights under this section does not terminate the
       
  2098 licenses of parties who have received copies or rights from you under
       
  2099 this License.  If your rights have been terminated and not permanently
       
  2100 reinstated, receipt of a copy of some or all of the same material does
       
  2101 not give you any rights to use it.

  2103 
       
  2104 10. FUTURE REVISIONS OF THIS LICENSE
       
  2105 
       
  2106 The Free Software Foundation may publish new, revised versions of the
       
  2107 GNU Free Documentation License from time to time.  Such new versions
       
  2108 will be similar in spirit to the present version, but may differ in
       
  2109 detail to address new problems or concerns.  See
       
  2110 http://www.gnu.org/copyleft/.
       
  2111 
       
  2112 Each version of the License is given a distinguishing version number.
       
  2113 If the Document specifies that a particular numbered version of this
       
  2114 License "or any later version" applies to it, you have the option of
       
  2115 following the terms and conditions either of that specified version or
       
  2116 of any later version that has been published (not as a draft) by the
       
  2117 Free Software Foundation.  If the Document does not specify a version
       
  2118 number of this License, you may choose any version ever published (not
       
  2119 as a draft) by the Free Software Foundation.  If the Document
       
  2120 specifies that a proxy can decide which future versions of this
       
  2121 License can be used, that proxy's public statement of acceptance of a
       
  2122 version permanently authorizes you to choose that version for the
       
  2123 Document.
       
  2124 
       
  2125 11. RELICENSING
       
  2126 
       
  2127 "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
       
  2128 World Wide Web server that publishes copyrightable works and also
       
  2129 provides prominent facilities for anybody to edit those works.  A
       
  2130 public wiki that anybody can edit is an example of such a server.  A
       
  2131 "Massive Multiauthor Collaboration" (or "MMC") contained in the site
       
  2132 means any set of copyrightable works thus published on the MMC site.
       
  2133 
       
  2134 "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 
       
  2135 license published by Creative Commons Corporation, a not-for-profit 
       
  2136 corporation with a principal place of business in San Francisco, 
       
  2137 California, as well as future copyleft versions of that license 
       
  2138 published by that same organization.
       
  2139 
       
  2140 "Incorporate" means to publish or republish a Document, in whole or in 
       
  2141 part, as part of another Document.
       
  2142 
       
  2143 An MMC is "eligible for relicensing" if it is licensed under this 
       
  2144 License, and if all works that were first published under this License 
       
  2145 somewhere other than this MMC, and subsequently incorporated in whole or 
       
  2146 in part into the MMC, (1) had no cover texts or invariant sections, and 
       
  2147 (2) were thus incorporated prior to November 1, 2008.
       
  2148 
       
  2149 The operator of an MMC Site may republish an MMC contained in the site
       
  2150 under CC-BY-SA on the same site at any time before August 1, 2009,
       
  2151 provided the MMC is eligible for relicensing.

  2154 ADDENDUM: How to use this License for your documents
       
  2155 
       
  2156 To use this License in a document you have written, include a copy of
       
  2157 the License in the document and put the following copyright and
       
  2158 license notices just after the title page:
       
  2159 
       
  2160     Copyright (c)  YEAR  YOUR NAME.
       
  2161     Permission is granted to copy, distribute and/or modify this document
       
  2162     under the terms of the GNU Free Documentation License, Version 1.3
       
  2163     or any later version published by the Free Software Foundation;
       
  2164     with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
       
  2165     A copy of the license is included in the section entitled "GNU
       
  2166     Free Documentation License".
       
  2167 
       
  2168 If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
       
  2169 replace the "with...Texts." line with this:
       
  2170 
       
  2171     with the Invariant Sections being LIST THEIR TITLES, with the
       
  2172     Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
       
  2173 
       
  2174 If you have Invariant Sections without Cover Texts, or some other
       
  2175 combination of the three, merge those two alternatives to suit the
       
  2176 situation.
       
  2177 
       
  2178 If your document contains nontrivial examples of program code, we
       
  2179 recommend releasing these examples in parallel under your choice of
       
  2180 free software license, such as the GNU General Public License,
       
  2181 to permit their use in free software.
