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

   597 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR

   599 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
       
   600 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

   603 
       
   604   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
       
   605 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
       
   606 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
       
   607 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
       
   608 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
       
   609 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
       
   610 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),

   615 
       
   616   If the disclaimer of warranty and limitation of liability provided
       
   617 above cannot be given local legal effect according to their terms,
       
   618 reviewing courts shall apply local law that most closely approximates
       
   619 an absolute waiver of all civil liability in connection with the
       
   620 Program, unless a warranty or assumption of liability accompanies a
       
   621 copy of the Program in return for a fee.

   624 
       
   625             How to Apply These Terms to Your New Programs
       
   626 
       
   627   If you develop a new program, and you want it to be of the greatest
       
   628 possible use to the public, the best way to achieve this is to make it
       
   629 free software which everyone can redistribute and change under these terms.
       
   630 
       
   631   To do so, attach the following notices to the program.  It is safest
       
   632 to attach them to the start of each source file to most effectively
       
   633 state the exclusion of warranty; and each file should have at least
       
   634 the "copyright" line and a pointer to where the full notice is found.
       
   635 
       
   636     <one line to give the program's name and a brief idea of what it does.>

   643

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

   648 
       
   649     You should have received a copy of the GNU General Public License
       
   650     along with this program.  If not, see <http://www.gnu.org/licenses/>.

   652 Also add information on how to contact you by electronic and paper mail.
       
   653 
       
   654   If the program does terminal interaction, make it output a short
       
   655 notice like this when it starts in an interactive mode:
       
   656 
       
   657     <program>  Copyright (C) <year>  <name of author>
       
   658     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
       
   659     This is free software, and you are welcome to redistribute it
       
   660     under certain conditions; type `show c' for details.
       
   661 
       
   662 The hypothetical commands `show w' and `show c' should show the appropriate
       
   663 parts of the General Public License.  Of course, your program's commands
       
   664 might be different; for a GUI interface, you would use an "about box".
       
   665 
       
   666   You should also get your employer (if you work as a programmer) or school,
       
   667 if any, to sign a "copyright disclaimer" for the program, if necessary.

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

   684  Everyone is permitted to copy and distribute verbatim copies
       
   685  of this license document, but changing it is not allowed.

   687 [This is the first released version of the Lesser GPL.  It also counts
       
   688  as the successor of the GNU Library Public License, version 2, hence

   690 
       
   691                             Preamble
       
   692 
       
   693   The licenses for most software are designed to take away your
       
   694 freedom to share and change it.  By contrast, the GNU General Public
       
   695 Licenses are intended to guarantee your freedom to share and change
       
   696 free software--to make sure the software is free for all its users.
       
   697 
       
   698   This license, the Lesser General Public License, applies to some
       
   699 specially designated software packages--typically libraries--of the
       
   700 Free Software Foundation and other authors who decide to use it.  You
       
   701 can use it too, but we suggest you first think carefully about whether
       
   702 this license or the ordinary General Public License is the better
       
   703 strategy to use in any particular case, based on the explanations below.
       
   704 
       
   705   When we speak of free software, we are referring to freedom of use,
       
   706 not price.  Our General Public Licenses are designed to make sure that
       
   707 you have the freedom to distribute copies of free software (and charge
       
   708 for this service if you wish); that you receive source code or can get
       
   709 it if you want it; that you can change the software and use pieces of
       
   710 it in new free programs; and that you are informed that you can do
       
   711 these things.
       
   712 
       
   713   To protect your rights, we need to make restrictions that forbid
       
   714 distributors to deny you these rights or to ask you to surrender these
       
   715 rights.  These restrictions translate to certain responsibilities for
       
   716 you if you distribute copies of the library or if you modify it.
       
   717 
       
   718   For example, if you distribute copies of the library, whether gratis
       
   719 or for a fee, you must give the recipients all the rights that we gave
       
   720 you.  You must make sure that they, too, receive or can get the source
       
   721 code.  If you link other code with the library, you must provide
       
   722 complete object files to the recipients, so that they can relink them
       
   723 with the library after making changes to the library and recompiling
       
   724 it.  And you must show them these terms so they know their rights.
       
   725 
       
   726   We protect your rights with a two-step method: (1) we copyright the
       
   727 library, and (2) we offer you this license, which gives you legal
       
   728 permission to copy, distribute and/or modify the library.
       
   729 
       
   730   To protect each distributor, we want to make it very clear that
       
   731 there is no warranty for the free library.  Also, if the library is
       
   732 modified by someone else and passed on, the recipients should know
       
   733 that what they have is not the original version, so that the original
       
   734 author's reputation will not be affected by problems that might be
       
   735 introduced by others.
       
   736 
       
   737   Finally, software patents pose a constant threat to the existence of
       
   738 any free program.  We wish to make sure that a company cannot
       
   739 effectively restrict the users of a free program by obtaining a
       
   740 restrictive license from a patent holder.  Therefore, we insist that
       
   741 any patent license obtained for a version of the library must be
       
   742 consistent with the full freedom of use specified in this license.
       
   743 
       
   744   Most GNU software, including some libraries, is covered by the
       
   745 ordinary GNU General Public License.  This license, the GNU Lesser
       
   746 General Public License, applies to certain designated libraries, and
       
   747 is quite different from the ordinary General Public License.  We use
       
   748 this license for certain libraries in order to permit linking those
       
   749 libraries into non-free programs.
       
   750 
       
   751   When a program is linked with a library, whether statically or using
       
   752 a shared library, the combination of the two is legally speaking a
       
   753 combined work, a derivative of the original library.  The ordinary
       
   754 General Public License therefore permits such linking only if the
       
   755 entire combination fits its criteria of freedom.  The Lesser General
       
   756 Public License permits more lax criteria for linking other code with
       
   757 the library.
       
   758 
       
   759   We call this license the "Lesser" General Public License because it
       
   760 does Less to protect the user's freedom than the ordinary General
       
   761 Public License.  It also provides other free software developers Less
       
   762 of an advantage over competing non-free programs.  These disadvantages
       
   763 are the reason we use the ordinary General Public License for many
       
   764 libraries.  However, the Lesser license provides advantages in certain
       
   765 special circumstances.
       
   766 
       
   767   For example, on rare occasions, there may be a special need to
       
   768 encourage the widest possible use of a certain library, so that it becomes
       
   769 a de-facto standard.  To achieve this, non-free programs must be
       
   770 allowed to use the library.  A more frequent case is that a free
       
   771 library does the same job as widely used non-free libraries.  In this
       
   772 case, there is little to gain by limiting the free library to free
       
   773 software only, so we use the Lesser General Public License.
       
   774 
       
   775   In other cases, permission to use a particular library in non-free
       
   776 programs enables a greater number of people to use a large body of
       
   777 free software.  For example, permission to use the GNU C Library in
       
   778 non-free programs enables many more people to use the whole GNU
       
   779 operating system, as well as its variant, the GNU/Linux operating
       
   780 system.
       
   781 
       
   782   Although the Lesser General Public License is Less protective of the
       
   783 users' freedom, it does ensure that the user of a program that is
       
   784 linked with the Library has the freedom and the wherewithal to run
       
   785 that program using a modified version of the Library.
       
   786 
       
   787   The precise terms and conditions for copying, distribution and
       
   788 modification follow.  Pay close attention to the difference between a
       
   789 "work based on the library" and a "work that uses the library".  The
       
   790 former contains code derived from the library, whereas the latter must
       
   791 be combined with the library in order to run.

   793 		 GNU LESSER GENERAL PUBLIC LICENSE 
       
   794    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 
       
   795 
       
   796   0. This License Agreement applies to any software library or other 
       
   797 program which contains a notice placed by the copyright holder or 
       
   798 other authorized party saying it may be distributed under the terms of 
       
   799 this Lesser General Public License (also called "this License"). 
       
   800 Each licensee is addressed as "you". 
       
   801 
       
   802   A "library" means a collection of software functions and/or data 
       
   803 prepared so as to be conveniently linked with application programs 
       
   804 (which use some of those functions and data) to form executables. 
       
   805 
       
   806   The "Library", below, refers to any such software library or work 
       
   807 which has been distributed under these terms.  A "work based on the 
       
   808 Library" means either the Library or any derivative work under 
       
   809 copyright law: that is to say, a work containing the Library or a 
       
   810 portion of it, either verbatim or with modifications and/or translated 
       
   811 straightforwardly into another language.  (Hereinafter, translation is 
       
   812 included without limitation in the term "modification".) 
       
   813 
       
   814   "Source code" for a work means the preferred form of the work for 
       
   815 making modifications to it.  For a library, complete source code means 
       
   816 all the source code for all modules it contains, plus any associated 
       
   817 interface definition files, plus the scripts used to control compilation 
       
   818 and installation of the library. 
       
   819 
       
   820   Activities other than copying, distribution and modification are not 
       
   821 covered by this License; they are outside its scope.  The act of 
       
   822 running a program using the Library is not restricted, and output from 
       
   823 such a program is covered only if its contents constitute a work based 
       
   824 on the Library (independent of the use of the Library in a tool for 
       
   825 writing it).  Whether that is true depends on what the Library does 
       
   826 and what the program that uses the Library does. 
       
   827   
       
   828   1. You may copy and distribute verbatim copies of the Library's 
       
   829 complete source code as you receive it, in any medium, provided that 
       
   830 you conspicuously and appropriately publish on each copy an 
       
   831 appropriate copyright notice and disclaimer of warranty; keep intact 
       
   832 all the notices that refer to this License and to the absence of any 
       
   833 warranty; and distribute a copy of this License along with the 
       
   834 Library. 
       
   835 
       
   836   You may charge a fee for the physical act of transferring a copy, 
       
   837 and you may at your option offer warranty protection in exchange for a 
       
   838 fee. 
       
   839 
       
   840 
       
   841   2. You may modify your copy or copies of the Library or any portion 
       
   842 of it, thus forming a work based on the Library, and copy and 
       
   843 distribute such modifications or work under the terms of Section 1 
       
   844 above, provided that you also meet all of these conditions: 
       
   845 
       
   846     a) The modified work must itself be a software library. 
       
   847 
       
   848     b) You must cause the files modified to carry prominent notices 
       
   849     stating that you changed the files and the date of any change. 
       
   850 
       
   851     c) You must cause the whole of the work to be licensed at no 
       
   852     charge to all third parties under the terms of this License. 
       
   853 
       
   854     d) If a facility in the modified Library refers to a function or a 
       
   855     table of data to be supplied by an application program that uses 
       
   856     the facility, other than as an argument passed when the facility 
       
   857     is invoked, then you must make a good faith effort to ensure that, 
       
   858     in the event an application does not supply such function or 
       
   859     table, the facility still operates, and performs whatever part of 
       
   860     its purpose remains meaningful. 
       
   861 
       
   862     (For example, a function in a library to compute square roots has 
       
   863     a purpose that is entirely well-defined independent of the 
       
   864     application.  Therefore, Subsection 2d requires that any 
       
   865     application-supplied function or table used by this function must 
       
   866     be optional: if the application does not supply it, the square 
       
   867     root function must still compute square roots.) 
       
   868 
       
   869 These requirements apply to the modified work as a whole.  If 
       
   870 identifiable sections of that work are not derived from the Library, 
       
   871 and can be reasonably considered independent and separate works in 
       
   872 themselves, then this License, and its terms, do not apply to those 
       
   873 sections when you distribute them as separate works.  But when you 
       
   874 distribute the same sections as part of a whole which is a work based 
       
   875 on the Library, the distribution of the whole must be on the terms of 
       
   876 this License, whose permissions for other licensees extend to the 
       
   877 entire whole, and thus to each and every part regardless of who wrote 
       
   878 it. 
       
   879 
       
   880 Thus, it is not the intent of this section to claim rights or contest 
       
   881 your rights to work written entirely by you; rather, the intent is to 
       
   882 exercise the right to control the distribution of derivative or 
       
   883 collective works based on the Library. 
       
   884 
       
   885 In addition, mere aggregation of another work not based on the Library 
       
   886 with the Library (or with a work based on the Library) on a volume of 
       
   887 a storage or distribution medium does not bring the other work under 
       
   888 the scope of this License. 
       
   889 
       
   890   3. You may opt to apply the terms of the ordinary GNU General Public 
       
   891 License instead of this License to a given copy of the Library.  To do 
       
   892 this, you must alter all the notices that refer to this License, so 
       
   893 that they refer to the ordinary GNU General Public License, version 2, 
       
   894 instead of to this License.  (If a newer version than version 2 of the 
       
   895 ordinary GNU General Public License has appeared, then you can specify 
       
   896 that version instead if you wish.)  Do not make any other change in 
       
   897 these notices. 
       
   898 
       
   899 
       
   900   Once this change is made in a given copy, it is irreversible for 
       
   901 that copy, so the ordinary GNU General Public License applies to all 
       
   902 subsequent copies and derivative works made from that copy. 
       
   903 
       
   904   This option is useful when you wish to copy part of the code of 
       
   905 the Library into a program that is not a library. 
       
   906 
       
   907   4. You may copy and distribute the Library (or a portion or 
       
   908 derivative of it, under Section 2) in object code or executable form 
       
   909 under the terms of Sections 1 and 2 above provided that you accompany 
       
   910 it with the complete corresponding machine-readable source code, which 
       
   911 must be distributed under the terms of Sections 1 and 2 above on a 
       
   912 medium customarily used for software interchange. 
       
   913 
       
   914   If distribution of object code is made by offering access to copy 
       
   915 from a designated place, then offering equivalent access to copy the 
       
   916 source code from the same place satisfies the requirement to 
       
   917 distribute the source code, even though third parties are not 
       
   918 compelled to copy the source along with the object code. 
       
   919 
       
   920   5. A program that contains no derivative of any portion of the 
       
   921 Library, but is designed to work with the Library by being compiled or 
       
   922 linked with it, is called a "work that uses the Library".  Such a 
       
   923 work, in isolation, is not a derivative work of the Library, and 
       
   924 therefore falls outside the scope of this License. 
       
   925 
       
   926   However, linking a "work that uses the Library" with the Library 
       
   927 creates an executable that is a derivative of the Library (because it 
       
   928 contains portions of the Library), rather than a "work that uses the 
       
   929 library".  The executable is therefore covered by this License. 
       
   930 Section 6 states terms for distribution of such executables. 
       
   931 
       
   932   When a "work that uses the Library" uses material from a header file 
       
   933 that is part of the Library, the object code for the work may be a 
       
   934 derivative work of the Library even though the source code is not. 
       
   935 Whether this is true is especially significant if the work can be 
       
   936 linked without the Library, or if the work is itself a library.  The 
       
   937 threshold for this to be true is not precisely defined by law. 
       
   938 
       
   939   If such an object file uses only numerical parameters, data 
       
   940 structure layouts and accessors, and small macros and small inline 
       
   941 functions (ten lines or less in length), then the use of the object 
       
   942 file is unrestricted, regardless of whether it is legally a derivative 
       
   943 work.  (Executables containing this object code plus portions of the 
       
   944 Library will still fall under Section 6.) 
       
   945 
       
   946   Otherwise, if the work is a derivative of the Library, you may 
       
   947 distribute the object code for the work under the terms of Section 6. 
       
   948 Any executables containing that work also fall under Section 6, 
       
   949 whether or not they are linked directly with the Library itself. 
       
   950 
       
   951 
       
   952   6. As an exception to the Sections above, you may also combine or 
       
   953 link a "work that uses the Library" with the Library to produce a 
       
   954 work containing portions of the Library, and distribute that work 
       
   955 under terms of your choice, provided that the terms permit 
       
   956 modification of the work for the customer's own use and reverse 
       
   957 engineering for debugging such modifications. 
       
   958 
       
   959   You must give prominent notice with each copy of the work that the 
       
   960 Library is used in it and that the Library and its use are covered by 
       
   961 this License.  You must supply a copy of this License.  If the work 
       
   962 during execution displays copyright notices, you must include the 
       
   963 copyright notice for the Library among them, as well as a reference 
       
   964 directing the user to the copy of this License.  Also, you must do one 
       
   965 of these things: 
       
   966 
       
   967     a) Accompany the work with the complete corresponding 
       
   968     machine-readable source code for the Library including whatever 
       
   969     changes were used in the work (which must be distributed under 
       
   970     Sections 1 and 2 above); and, if the work is an executable linked 
       
   971     with the Library, with the complete machine-readable "work that 
       
   972     uses the Library", as object code and/or source code, so that the 
       
   973     user can modify the Library and then relink to produce a modified 
       
   974     executable containing the modified Library.  (It is understood 
       
   975     that the user who changes the contents of definitions files in the 
       
   976     Library will not necessarily be able to recompile the application 
       
   977     to use the modified definitions.) 
       
   978 
       
   979     b) Use a suitable shared library mechanism for linking with the 
       
   980     Library.  A suitable mechanism is one that (1) uses at run time a 
       
   981     copy of the library already present on the user's computer system, 
       
   982     rather than copying library functions into the executable, and (2) 
       
   983     will operate properly with a modified version of the library, if 
       
   984     the user installs one, as long as the modified version is 
       
   985     interface-compatible with the version that the work was made with. 
       
   986 
       
   987     c) Accompany the work with a written offer, valid for at 
       
   988     least three years, to give the same user the materials 
       
   989     specified in Subsection 6a, above, for a charge no more 
       
   990     than the cost of performing this distribution. 
       
   991 
       
   992     d) If distribution of the work is made by offering access to copy 
       
   993     from a designated place, offer equivalent access to copy the above 
       
   994     specified materials from the same place. 
       
   995 
       
   996     e) Verify that the user has already received a copy of these 
       
   997     materials or that you have already sent this user a copy. 
       
   998 
       
   999   For an executable, the required form of the "work that uses the 
       
  1000 Library" must include any data and utility programs needed for 
       
  1001 reproducing the executable from it.  However, as a special exception, 
       
  1002 the materials to be distributed need not include anything that is 
       
  1003 normally distributed (in either source or binary form) with the major 
       
  1004 components (compiler, kernel, and so on) of the operating system on 
       
  1005 which the executable runs, unless that component itself accompanies 
       
  1006 the executable. 
       
  1007 
       
  1008   It may happen that this requirement contradicts the license 
       
  1009 restrictions of other proprietary libraries that do not normally 
       
  1010 accompany the operating system.  Such a contradiction means you cannot 
       
  1011 use both them and the Library together in an executable that you 
       
  1012 distribute. 
       
  1013 
       
  1014 
       
  1015   7. You may place library facilities that are a work based on the 
       
  1016 Library side-by-side in a single library together with other library 
       
  1017 facilities not covered by this License, and distribute such a combined 
       
  1018 library, provided that the separate distribution of the work based on 
       
  1019 the Library and of the other library facilities is otherwise 
       
  1020 permitted, and provided that you do these two things: 
       
  1021 
       
  1022     a) Accompany the combined library with a copy of the same work 
       
  1023     based on the Library, uncombined with any other library 
       
  1024     facilities.  This must be distributed under the terms of the 
       
  1025     Sections above. 
       
  1026 
       
  1027     b) Give prominent notice with the combined library of the fact 
       
  1028     that part of it is a work based on the Library, and explaining 
       
  1029     where to find the accompanying uncombined form of the same work. 
       
  1030 
       
  1031   8. You may not copy, modify, sublicense, link with, or distribute 
       
  1032 the Library except as expressly provided under this License.  Any 
       
  1033 attempt otherwise to copy, modify, sublicense, link with, or 
       
  1034 distribute the Library is void, and will automatically terminate your 
       
  1035 rights under this License.  However, parties who have received copies, 
       
  1036 or rights, from you under this License will not have their licenses 
       
  1037 terminated so long as such parties remain in full compliance. 
       
  1038 
       
  1039   9. You are not required to accept this License, since you have not 
       
  1040 signed it.  However, nothing else grants you permission to modify or 
       
  1041 distribute the Library or its derivative works.  These actions are 
       
  1042 prohibited by law if you do not accept this License.  Therefore, by 
       
  1043 modifying or distributing the Library (or any work based on the 
       
  1044 Library), you indicate your acceptance of this License to do so, and 
       
  1045 all its terms and conditions for copying, distributing or modifying 
       
  1046 the Library or works based on it. 
       
  1047 
       
  1048   10. Each time you redistribute the Library (or any work based on the 
       
  1049 Library), the recipient automatically receives a license from the 
       
  1050 original licensor to copy, distribute, link with or modify the Library 
       
  1051 subject to these terms and conditions.  You may not impose any further 
       
  1052 restrictions on the recipients' exercise of the rights granted herein. 
       
  1053 You are not responsible for enforcing compliance by third parties with 
       
  1054 this License. 
       
  1055 
       
  1056 
       
  1057   11. If, as a consequence of a court judgment or allegation of patent 
       
  1058 infringement or for any other reason (not limited to patent issues), 
       
  1059 conditions are imposed on you (whether by court order, agreement or 
       
  1060 otherwise) that contradict the conditions of this License, they do not 
       
  1061 excuse you from the conditions of this License.  If you cannot 
       
  1062 distribute so as to satisfy simultaneously your obligations under this 
       
  1063 License and any other pertinent obligations, then as a consequence you 
       
  1064 may not distribute the Library at all.  For example, if a patent 
       
  1065 license would not permit royalty-free redistribution of the Library by 
       
  1066 all those who receive copies directly or indirectly through you, then 
       
  1067 the only way you could satisfy both it and this License would be to 
       
  1068 refrain entirely from distribution of the Library. 
       
  1069 
       
  1070 If any portion of this section is held invalid or unenforceable under any 
       
  1071 particular circumstance, the balance of the section is intended to apply, 
       
  1072 and the section as a whole is intended to apply in other circumstances. 
       
  1073 
       
  1074 It is not the purpose of this section to induce you to infringe any 
       
  1075 patents or other property right claims or to contest validity of any 
       
  1076 such claims; this section has the sole purpose of protecting the 
       
  1077 integrity of the free software distribution system which is 
       
  1078 implemented by public license practices.  Many people have made 
       
  1079 generous contributions to the wide range of software distributed 
       
  1080 through that system in reliance on consistent application of that 
       
  1081 system; it is up to the author/donor to decide if he or she is willing 
       
  1082 to distribute software through any other system and a licensee cannot 
       
  1083 impose that choice. 
       
  1084 
       
  1085 This section is intended to make thoroughly clear what is believed to 
       
  1086 be a consequence of the rest of this License. 
       
  1087 
       
  1088   12. If the distribution and/or use of the Library is restricted in 
       
  1089 certain countries either by patents or by copyrighted interfaces, the 
       
  1090 original copyright holder who places the Library under this License may add 
       
  1091 an explicit geographical distribution limitation excluding those countries, 
       
  1092 so that distribution is permitted only in or among countries not thus 
       
  1093 excluded.  In such case, this License incorporates the limitation as if 
       
  1094 written in the body of this License. 
       
  1095 
       
  1096   13. The Free Software Foundation may publish revised and/or new 
       
  1097 versions of the Lesser General Public License from time to time. 
       
  1098 Such new versions will be similar in spirit to the present version, 
       
  1099 but may differ in detail to address new problems or concerns. 
       
  1100 
       
  1101 Each version is given a distinguishing version number.  If the Library 
       
  1102 specifies a version number of this License which applies to it and 
       
  1103 "any later version", you have the option of following the terms and 
       
  1104 conditions either of that version or of any later version published by 
       
  1105 the Free Software Foundation.  If the Library does not specify a 
       
  1106 license version number, you may choose any version ever published by 
       
  1107 the Free Software Foundation. 
       
  1108 
       
  1109 
       
  1110   14. If you wish to incorporate parts of the Library into other free 
       
  1111 programs whose distribution conditions are incompatible with these, 
       
  1112 write to the author to ask for permission.  For software which is 
       
  1113 copyrighted by the Free Software Foundation, write to the Free 
       
  1114 Software Foundation; we sometimes make exceptions for this.  Our 
       
  1115 decision will be guided by the two goals of preserving the free status 
       
  1116 of all derivatives of our free software and of promoting the sharing 
       
  1117 and reuse of software generally. 
       
  1118 
       
  1119 			    NO WARRANTY 
       
  1120 
       
  1121   15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO 
       
  1122 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. 
       
  1123 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR 
       
  1124 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY 
       
  1125 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE 
       
  1126 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 
       
  1127 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE 
       
  1128 LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME 
       
  1129 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 
       
  1130 
       
  1131   16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN 
       
  1132 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY 
       
  1133 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU 
       
  1134 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR 
       
  1135 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE 
       
  1136 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING 
       
  1137 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A 
       
  1138 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF 
       
  1139 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH 
       
  1140 DAMAGES. 
       
  1141 
       
  1142 		     END OF TERMS AND CONDITIONS 
       
  1143 
       
  1144 
       
  1145            How to Apply These Terms to Your New Libraries 
       
  1146 
       
  1147   If you develop a new library, and you want it to be of the greatest 
       
  1148 possible use to the public, we recommend making it free software that 
       
  1149 everyone can redistribute and change.  You can do so by permitting 
       
  1150 redistribution under these terms (or, alternatively, under the terms of the 
       
  1151 ordinary General Public License). 
       
  1152 
       
  1153   To apply these terms, attach the following notices to the library.  It is 
       
  1154 safest to attach them to the start of each source file to most effectively 
       
  1155 convey the exclusion of warranty; and each file should have at least the 
       
  1156 "copyright" line and a pointer to where the full notice is found. 
       
  1157 
       
  1158     <one line to give the library's name and a brief idea of what it does.> 
       
  1159     Copyright (C) <year>  <name of author> 
       
  1160 
       
  1161     This library is free software; you can redistribute it and/or 
       
  1162     modify it under the terms of the GNU Lesser General Public 
       
  1163     License as published by the Free Software Foundation; either 
       
  1164     version 2.1 of the License, or (at your option) any later version. 
       
  1165 
       
  1166     This library is distributed in the hope that it will be useful, 
       
  1167     but WITHOUT ANY WARRANTY; without even the implied warranty of 
       
  1168     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU 
       
  1169     Lesser General Public License for more details. 
       
  1170 
       
  1171     You should have received a copy of the GNU Lesser General Public 
       
  1172     License along with this library; if not, write to the Free Software 
       
  1173     Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA 
       
  1174 
       
  1175 Also add information on how to contact you by electronic and paper mail.

  1177 You should also get your employer (if you work as a programmer) or your 
       
  1178 school, if any, to sign a "copyright disclaimer" for the library, if 
       
  1179 necessary.  Here is a sample; alter the names:

  1196  Everyone is permitted to copy and distribute verbatim copies
       
  1197  of this license document, but changing it is not allowed.
       
  1198 
       
  1199 0. PREAMBLE
       
  1200 
       
  1201 The purpose of this License is to make a manual, textbook, or other
       
  1202 functional and useful document "free" in the sense of freedom: to
       
  1203 assure everyone the effective freedom to copy and redistribute it,
       
  1204 with or without modifying it, either commercially or noncommercially.
       
  1205 Secondarily, this License preserves for the author and publisher a way
       
  1206 to get credit for their work, while not being considered responsible
       
  1207 for modifications made by others.
       
  1208 
       
  1209 This License is a kind of "copyleft", which means that derivative
       
  1210 works of the document must themselves be free in the same sense.  It
       
  1211 complements the GNU General Public License, which is a copyleft
       
  1212 license designed for free software.
       
  1213 
       
  1214 We have designed this License in order to use it for manuals for free
       
  1215 software, because free software needs free documentation: a free
       
  1216 program should come with manuals providing the same freedoms that the
       
  1217 software does.  But this License is not limited to software manuals;
       
  1218 it can be used for any textual work, regardless of subject matter or
       
  1219 whether it is published as a printed book.  We recommend this License
       
  1220 principally for works whose purpose is instruction or reference.
       
  1221 
       
  1222 
       
  1223 1. APPLICABILITY AND DEFINITIONS
       
  1224 
       
  1225 This License applies to any manual or other work, in any medium, that
       
  1226 contains a notice placed by the copyright holder saying it can be
       
  1227 distributed under the terms of this License.  Such a notice grants a
       
  1228 world-wide, royalty-free license, unlimited in duration, to use that
       
  1229 work under the conditions stated herein.  The "Document", below,
       
  1230 refers to any such manual or work.  Any member of the public is a
       
  1231 licensee, and is addressed as "you".  You accept the license if you
       
  1232 copy, modify or distribute the work in a way requiring permission
       
  1233 under copyright law.
       
  1234 
       
  1235 A "Modified Version" of the Document means any work containing the
       
  1236 Document or a portion of it, either copied verbatim, or with
       
  1237 modifications and/or translated into another language.
       
  1238 
       
  1239 A "Secondary Section" is a named appendix or a front-matter section of
       
  1240 the Document that deals exclusively with the relationship of the
       
  1241 publishers or authors of the Document to the Document's overall
       
  1242 subject (or to related matters) and contains nothing that could fall
       
  1243 directly within that overall subject.  (Thus, if the Document is in
       
  1244 part a textbook of mathematics, a Secondary Section may not explain
       
  1245 any mathematics.)  The relationship could be a matter of historical
       
  1246 connection with the subject or with related matters, or of legal,
       
  1247 commercial, philosophical, ethical or political position regarding
       
  1248 them.
       
  1249 
       
  1250 The "Invariant Sections" are certain Secondary Sections whose titles
       
  1251 are designated, as being those of Invariant Sections, in the notice
       
  1252 that says that the Document is released under this License.  If a
       
  1253 section does not fit the above definition of Secondary then it is not
       
  1254 allowed to be designated as Invariant.  The Document may contain zero
       
  1255 Invariant Sections.  If the Document does not identify any Invariant
       
  1256 Sections then there are none.
       
  1257 
       
  1258 The "Cover Texts" are certain short passages of text that are listed,
       
  1259 as Front-Cover Texts or Back-Cover Texts, in the notice that says that
       
  1260 the Document is released under this License.  A Front-Cover Text may
       
  1261 be at most 5 words, and a Back-Cover Text may be at most 25 words.
       
  1262 
       
  1263 A "Transparent" copy of the Document means a machine-readable copy,
       
  1264 represented in a format whose specification is available to the
       
  1265 general public, that is suitable for revising the document
       
  1266 straightforwardly with generic text editors or (for images composed of
       
  1267 pixels) generic paint programs or (for drawings) some widely available
       
  1268 drawing editor, and that is suitable for input to text formatters or
       
  1269 for automatic translation to a variety of formats suitable for input
       
  1270 to text formatters.  A copy made in an otherwise Transparent file
       
  1271 format whose markup, or absence of markup, has been arranged to thwart
       
  1272 or discourage subsequent modification by readers is not Transparent.
       
  1273 An image format is not Transparent if used for any substantial amount
       
  1274 of text.  A copy that is not "Transparent" is called "Opaque".
       
  1275 
       
  1276 Examples of suitable formats for Transparent copies include plain
       
  1277 ASCII without markup, Texinfo input format, LaTeX input format, SGML
       
  1278 or XML using a publicly available DTD, and standard-conforming simple
       
  1279 HTML, PostScript or PDF designed for human modification.  Examples of
       
  1280 transparent image formats include PNG, XCF and JPG.  Opaque formats
       
  1281 include proprietary formats that can be read and edited only by
       
  1282 proprietary word processors, SGML or XML for which the DTD and/or
       
  1283 processing tools are not generally available, and the
       
  1284 machine-generated HTML, PostScript or PDF produced by some word
       
  1285 processors for output purposes only.
       
  1286 
       
  1287 The "Title Page" means, for a printed book, the title page itself,
       
  1288 plus such following pages as are needed to hold, legibly, the material
       
  1289 this License requires to appear in the title page.  For works in
       
  1290 formats which do not have any title page as such, "Title Page" means
       
  1291 the text near the most prominent appearance of the work's title,
       
  1292 preceding the beginning of the body of the text.
       
  1293 
       
  1294 The "publisher" means any person or entity that distributes copies of
       
  1295 the Document to the public.
       
  1296 
       
  1297 A section "Entitled XYZ" means a named subunit of the Document whose
       
  1298 title either is precisely XYZ or contains XYZ in parentheses following
       
  1299 text that translates XYZ in another language.  (Here XYZ stands for a
       
  1300 specific section name mentioned below, such as "Acknowledgements",
       
  1301 "Dedications", "Endorsements", or "History".)  To "Preserve the Title"
       
  1302 of such a section when you modify the Document means that it remains a
       
  1303 section "Entitled XYZ" according to this definition.
       
  1304 
       
  1305 The Document may include Warranty Disclaimers next to the notice which
       
  1306 states that this License applies to the Document.  These Warranty
       
  1307 Disclaimers are considered to be included by reference in this
       
  1308 License, but only as regards disclaiming warranties: any other
       
  1309 implication that these Warranty Disclaimers may have is void and has
       
  1310 no effect on the meaning of this License.
       
  1311 
       
  1312 2. VERBATIM COPYING
       
  1313 
       
  1314 You may copy and distribute the Document in any medium, either
       
  1315 commercially or noncommercially, provided that this License, the
       
  1316 copyright notices, and the license notice saying this License applies
       
  1317 to the Document are reproduced in all copies, and that you add no
       
  1318 other conditions whatsoever to those of this License.  You may not use
       
  1319 technical measures to obstruct or control the reading or further
       
  1320 copying of the copies you make or distribute.  However, you may accept
       
  1321 compensation in exchange for copies.  If you distribute a large enough
       
  1322 number of copies you must also follow the conditions in section 3.
       
  1323 
       
  1324 You may also lend copies, under the same conditions stated above, and
       
  1325 you may publicly display copies.
       
  1326 
       
  1327 
       
  1328 3. COPYING IN QUANTITY
       
  1329 
       
  1330 If you publish printed copies (or copies in media that commonly have
       
  1331 printed covers) of the Document, numbering more than 100, and the
       
  1332 Document's license notice requires Cover Texts, you must enclose the
       
  1333 copies in covers that carry, clearly and legibly, all these Cover
       
  1334 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
       
  1335 the back cover.  Both covers must also clearly and legibly identify
       
  1336 you as the publisher of these copies.  The front cover must present
       
  1337 the full title with all words of the title equally prominent and
       
  1338 visible.  You may add other material on the covers in addition.
       
  1339 Copying with changes limited to the covers, as long as they preserve
       
  1340 the title of the Document and satisfy these conditions, can be treated
       
  1341 as verbatim copying in other respects.
       
  1342 
       
  1343 If the required texts for either cover are too voluminous to fit
       
  1344 legibly, you should put the first ones listed (as many as fit
       
  1345 reasonably) on the actual cover, and continue the rest onto adjacent
       
  1346 pages.
       
  1347 
       
  1348 If you publish or distribute Opaque copies of the Document numbering
       
  1349 more than 100, you must either include a machine-readable Transparent
       
  1350 copy along with each Opaque copy, or state in or with each Opaque copy
       
  1351 a computer-network location from which the general network-using
       
  1352 public has access to download using public-standard network protocols
       
  1353 a complete Transparent copy of the Document, free of added material.
       
  1354 If you use the latter option, you must take reasonably prudent steps,
       
  1355 when you begin distribution of Opaque copies in quantity, to ensure
       
  1356 that this Transparent copy will remain thus accessible at the stated
       
  1357 location until at least one year after the last time you distribute an
       
  1358 Opaque copy (directly or through your agents or retailers) of that
       
  1359 edition to the public.
       
  1360 
       
  1361 It is requested, but not required, that you contact the authors of the
       
  1362 Document well before redistributing any large number of copies, to
       
  1363 give them a chance to provide you with an updated version of the
       
  1364 Document.
       
  1365 
       
  1366 
       
  1367 4. MODIFICATIONS
       
  1368 
       
  1369 You may copy and distribute a Modified Version of the Document under
       
  1370 the conditions of sections 2 and 3 above, provided that you release
       
  1371 the Modified Version under precisely this License, with the Modified
       
  1372 Version filling the role of the Document, thus licensing distribution
       
  1373 and modification of the Modified Version to whoever possesses a copy
       
  1374 of it.  In addition, you must do these things in the Modified Version:
       
  1375 
       
  1376 A. Use in the Title Page (and on the covers, if any) a title distinct
       
  1377    from that of the Document, and from those of previous versions
       
  1378    (which should, if there were any, be listed in the History section
       
  1379    of the Document).  You may use the same title as a previous version
       
  1380    if the original publisher of that version gives permission.
       
  1381 B. List on the Title Page, as authors, one or more persons or entities
       
  1382    responsible for authorship of the modifications in the Modified
       
  1383    Version, together with at least five of the principal authors of the
       
  1384    Document (all of its principal authors, if it has fewer than five),
       
  1385    unless they release you from this requirement.
       
  1386 C. State on the Title page the name of the publisher of the
       
  1387    Modified Version, as the publisher.
       
  1388 D. Preserve all the copyright notices of the Document.
       
  1389 E. Add an appropriate copyright notice for your modifications
       
  1390    adjacent to the other copyright notices.
       
  1391 F. Include, immediately after the copyright notices, a license notice
       
  1392    giving the public permission to use the Modified Version under the
       
  1393    terms of this License, in the form shown in the Addendum below.
       
  1394 G. Preserve in that license notice the full lists of Invariant Sections
       
  1395    and required Cover Texts given in the Document's license notice.
       
  1396 H. Include an unaltered copy of this License.
       
  1397 I. Preserve the section Entitled "History", Preserve its Title, and add
       
  1398    to it an item stating at least the title, year, new authors, and
       
  1399    publisher of the Modified Version as given on the Title Page.  If
       
  1400    there is no section Entitled "History" in the Document, create one
       
  1401    stating the title, year, authors, and publisher of the Document as
       
  1402    given on its Title Page, then add an item describing the Modified
       
  1403    Version as stated in the previous sentence.
       
  1404 J. Preserve the network location, if any, given in the Document for
       
  1405    public access to a Transparent copy of the Document, and likewise
       
  1406    the network locations given in the Document for previous versions
       
  1407    it was based on.  These may be placed in the "History" section.
       
  1408    You may omit a network location for a work that was published at
       
  1409    least four years before the Document itself, or if the original
       
  1410    publisher of the version it refers to gives permission.
       
  1411 K. For any section Entitled "Acknowledgements" or "Dedications",
       
  1412    Preserve the Title of the section, and preserve in the section all
       
  1413    the substance and tone of each of the contributor acknowledgements
       
  1414    and/or dedications given therein.
       
  1415 L. Preserve all the Invariant Sections of the Document,
       
  1416    unaltered in their text and in their titles.  Section numbers
       
  1417    or the equivalent are not considered part of the section titles.
       
  1418 M. Delete any section Entitled "Endorsements".  Such a section
       
  1419    may not be included in the Modified Version.
       
  1420 N. Do not retitle any existing section to be Entitled "Endorsements"
       
  1421    or to conflict in title with any Invariant Section.
       
  1422 O. Preserve any Warranty Disclaimers.
       
  1423 
       
  1424 If the Modified Version includes new front-matter sections or
       
  1425 appendices that qualify as Secondary Sections and contain no material
       
  1426 copied from the Document, you may at your option designate some or all
       
  1427 of these sections as invariant.  To do this, add their titles to the
       
  1428 list of Invariant Sections in the Modified Version's license notice.
       
  1429 These titles must be distinct from any other section titles.
       
  1430 
       
  1431 You may add a section Entitled "Endorsements", provided it contains
       
  1432 nothing but endorsements of your Modified Version by various
       
  1433 parties--for example, statements of peer review or that the text has
       
  1434 been approved by an organization as the authoritative definition of a
       
  1435 standard.
       
  1436 
       
  1437 You may add a passage of up to five words as a Front-Cover Text, and a
       
  1438 passage of up to 25 words as a Back-Cover Text, to the end of the list
       
  1439 of Cover Texts in the Modified Version.  Only one passage of
       
  1440 Front-Cover Text and one of Back-Cover Text may be added by (or
       
  1441 through arrangements made by) any one entity.  If the Document already
       
  1442 includes a cover text for the same cover, previously added by you or
       
  1443 by arrangement made by the same entity you are acting on behalf of,
       
  1444 you may not add another; but you may replace the old one, on explicit
       
  1445 permission from the previous publisher that added the old one.
       
  1446 
       
  1447 The author(s) and publisher(s) of the Document do not by this License
       
  1448 give permission to use their names for publicity for or to assert or
       
  1449 imply endorsement of any Modified Version.
       
  1450 
       
  1451 
       
  1452 5. COMBINING DOCUMENTS
       
  1453 
       
  1454 You may combine the Document with other documents released under this
       
  1455 License, under the terms defined in section 4 above for modified
       
  1456 versions, provided that you include in the combination all of the
       
  1457 Invariant Sections of all of the original documents, unmodified, and
       
  1458 list them all as Invariant Sections of your combined work in its
       
  1459 license notice, and that you preserve all their Warranty Disclaimers.
       
  1460 
       
  1461 The combined work need only contain one copy of this License, and
       
  1462 multiple identical Invariant Sections may be replaced with a single
       
  1463 copy.  If there are multiple Invariant Sections with the same name but
       
  1464 different contents, make the title of each such section unique by
       
  1465 adding at the end of it, in parentheses, the name of the original
       
  1466 author or publisher of that section if known, or else a unique number.
       
  1467 Make the same adjustment to the section titles in the list of
       
  1468 Invariant Sections in the license notice of the combined work.
       
  1469 
       
  1470 In the combination, you must combine any sections Entitled "History"
       
  1471 in the various original documents, forming one section Entitled
       
  1472 "History"; likewise combine any sections Entitled "Acknowledgements",
       
  1473 and any sections Entitled "Dedications".  You must delete all sections
       
  1474 Entitled "Endorsements".

  1477 6. COLLECTIONS OF DOCUMENTS
       
  1478 
       
  1479 You may make a collection consisting of the Document and other
       
  1480 documents released under this License, and replace the individual
       
  1481 copies of this License in the various documents with a single copy
       
  1482 that is included in the collection, provided that you follow the rules
       
  1483 of this License for verbatim copying of each of the documents in all
       
  1484 other respects.
       
  1485 
       
  1486 You may extract a single document from such a collection, and
       
  1487 distribute it individually under this License, provided you insert a
       
  1488 copy of this License into the extracted document, and follow this
       
  1489 License in all other respects regarding verbatim copying of that
       
  1490 document.
       
  1491 
       
  1492 
       
  1493 7. AGGREGATION WITH INDEPENDENT WORKS
       
  1494 
       
  1495 A compilation of the Document or its derivatives with other separate
       
  1496 and independent documents or works, in or on a volume of a storage or
       
  1497 distribution medium, is called an "aggregate" if the copyright
       
  1498 resulting from the compilation is not used to limit the legal rights
       
  1499 of the compilation's users beyond what the individual works permit.
       
  1500 When the Document is included in an aggregate, this License does not
       
  1501 apply to the other works in the aggregate which are not themselves
       
  1502 derivative works of the Document.
       
  1503 
       
  1504 If the Cover Text requirement of section 3 is applicable to these
       
  1505 copies of the Document, then if the Document is less than one half of
       
  1506 the entire aggregate, the Document's Cover Texts may be placed on
       
  1507 covers that bracket the Document within the aggregate, or the
       
  1508 electronic equivalent of covers if the Document is in electronic form.
       
  1509 Otherwise they must appear on printed covers that bracket the whole
       
  1510 aggregate.
       
  1511 
       
  1512 
       
  1513 8. TRANSLATION
       
  1514 
       
  1515 Translation is considered a kind of modification, so you may
       
  1516 distribute translations of the Document under the terms of section 4.
       
  1517 Replacing Invariant Sections with translations requires special
       
  1518 permission from their copyright holders, but you may include
       
  1519 translations of some or all Invariant Sections in addition to the
       
  1520 original versions of these Invariant Sections.  You may include a
       
  1521 translation of this License, and all the license notices in the
       
  1522 Document, and any Warranty Disclaimers, provided that you also include
       
  1523 the original English version of this License and the original versions
       
  1524 of those notices and disclaimers.  In case of a disagreement between
       
  1525 the translation and the original version of this License or a notice
       
  1526 or disclaimer, the original version will prevail.
       
  1527 
       
  1528 If a section in the Document is Entitled "Acknowledgements",
       
  1529 "Dedications", or "History", the requirement (section 4) to Preserve
       
  1530 its Title (section 1) will typically require changing the actual
       
  1531 title.
       
  1532 
       
  1533 
       
  1534 9. TERMINATION
       
  1535 
       
  1536 You may not copy, modify, sublicense, or distribute the Document
       
  1537 except as expressly provided under this License.  Any attempt
       
  1538 otherwise to copy, modify, sublicense, or distribute it is void, and
       
  1539 will automatically terminate your rights under this License.
       
  1540 
       
  1541 However, if you cease all violation of this License, then your license
       
  1542 from a particular copyright holder is reinstated (a) provisionally,
       
  1543 unless and until the copyright holder explicitly and finally
       
  1544 terminates your license, and (b) permanently, if the copyright holder
       
  1545 fails to notify you of the violation by some reasonable means prior to
       
  1546 60 days after the cessation.
       
  1547 
       
  1548 Moreover, your license from a particular copyright holder is
       
  1549 reinstated permanently if the copyright holder notifies you of the
       
  1550 violation by some reasonable means, this is the first time you have
       
  1551 received notice of violation of this License (for any work) from that
       
  1552 copyright holder, and you cure the violation prior to 30 days after
       
  1553 your receipt of the notice.
       
  1554 
       
  1555 Termination of your rights under this section does not terminate the
       
  1556 licenses of parties who have received copies or rights from you under
       
  1557 this License.  If your rights have been terminated and not permanently
       
  1558 reinstated, receipt of a copy of some or all of the same material does
       
  1559 not give you any rights to use it.
       
  1560 
       
  1561 
       
  1562 10. FUTURE REVISIONS OF THIS LICENSE
       
  1563 
       
  1564 The Free Software Foundation may publish new, revised versions of the
       
  1565 GNU Free Documentation License from time to time.  Such new versions
       
  1566 will be similar in spirit to the present version, but may differ in
       
  1567 detail to address new problems or concerns.  See
       
  1568 http://www.gnu.org/copyleft/.
       
  1569 
       
  1570 Each version of the License is given a distinguishing version number.
       
  1571 If the Document specifies that a particular numbered version of this
       
  1572 License "or any later version" applies to it, you have the option of
       
  1573 following the terms and conditions either of that specified version or
       
  1574 of any later version that has been published (not as a draft) by the
       
  1575 Free Software Foundation.  If the Document does not specify a version
       
  1576 number of this License, you may choose any version ever published (not
       
  1577 as a draft) by the Free Software Foundation.  If the Document
       
  1578 specifies that a proxy can decide which future versions of this
       
  1579 License can be used, that proxy's public statement of acceptance of a
       
  1580 version permanently authorizes you to choose that version for the
       
  1581 Document.
       
  1582 
       
  1583 11. RELICENSING
       
  1584 
       
  1585 "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
       
  1586 World Wide Web server that publishes copyrightable works and also
       
  1587 provides prominent facilities for anybody to edit those works.  A
       
  1588 public wiki that anybody can edit is an example of such a server.  A
       
  1589 "Massive Multiauthor Collaboration" (or "MMC") contained in the site
       
  1590 means any set of copyrightable works thus published on the MMC site.
       
  1591 
       
  1592 "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 
       
  1593 license published by Creative Commons Corporation, a not-for-profit 
       
  1594 corporation with a principal place of business in San Francisco, 
       
  1595 California, as well as future copyleft versions of that license 
       
  1596 published by that same organization.
       
  1597 
       
  1598 "Incorporate" means to publish or republish a Document, in whole or in 
       
  1599 part, as part of another Document.
       
  1600 
       
  1601 An MMC is "eligible for relicensing" if it is licensed under this 
       
  1602 License, and if all works that were first published under this License 
       
  1603 somewhere other than this MMC, and subsequently incorporated in whole or 
       
  1604 in part into the MMC, (1) had no cover texts or invariant sections, and 
       
  1605 (2) were thus incorporated prior to November 1, 2008.
       
  1606 
       
  1607 The operator of an MMC Site may republish an MMC contained in the site
       
  1608 under CC-BY-SA on the same site at any time before August 1, 2009,
       
  1609 provided the MMC is eligible for relicensing.

  1611 
       
  1612 ADDENDUM: How to use this License for your documents
       
  1613 
       
  1614 To use this License in a document you have written, include a copy of
       
  1615 the License in the document and put the following copyright and
       
  1616 license notices just after the title page:
       
  1617 
       
  1618     Copyright (c)  YEAR  YOUR NAME.
       
  1619     Permission is granted to copy, distribute and/or modify this document
       
  1620     under the terms of the GNU Free Documentation License, Version 1.3
       
  1621     or any later version published by the Free Software Foundation;
       
  1622     with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
       
  1623     A copy of the license is included in the section entitled "GNU
       
  1624     Free Documentation License".
       
  1625 
       
  1626 If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
       
  1627 replace the "with...Texts." line with this:
       
  1628 
       
  1629     with the Invariant Sections being LIST THEIR TITLES, with the
       
  1630     Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
       
  1631 
       
  1632 If you have Invariant Sections without Cover Texts, or some other
       
  1633 combination of the three, merge those two alternatives to suit the
       
  1634 situation.
       
  1635 
       
  1636 If your document contains nontrivial examples of program code, we
       
  1637 recommend releasing these examples in parallel under your choice of
       
  1638 free software license, such as the GNU General Public License,
       
  1639 to permit their use in free software.
