      9 In TLS-enabled builds, compliance with the licenses of the libraries
     10 with which GNU libmicrohttpd is linked automatically constrains the
     11 available license options as follows:
     12     * If linked only with GnuTLS, the only available license option
     13       is the GNU Lesser General Public License version 2.1 or any
     14       later version.
     15     * If linked with OpenSSL, MbedTLS, or both, the only available
     16       license option is the GNU Lesser General Public License
     17       version 3 or any later version; this remains the case regardless
     18       of whether GnuTLS is also used in the same build.
     19 Accordingly, in TLS-enabled builds the alternative "GNU General
     20 Public License version 2 or any later version with the eCos 2.0
     21 exception" option is unavailable.

     30 
     31  Copyright (C) 1991, 1999 Free Software Foundation, Inc.
     32  <https://fsf.org/>
     33  Everyone is permitted to copy and distribute verbatim copies
     34  of this license document, but changing it is not allowed.
     35 
     36 [This is the first released version of the Lesser GPL.  It also counts
     37  as the successor of the GNU Library Public License, version 2, hence
     38  the version number 2.1.]
     39 
     40                             Preamble
     41 
     42   The licenses for most software are designed to take away your
     43 freedom to share and change it.  By contrast, the GNU General Public
     44 Licenses are intended to guarantee your freedom to share and change
     45 free software--to make sure the software is free for all its users.
     46 
     47   This license, the Lesser General Public License, applies to some
     48 specially designated software packages--typically libraries--of the
     49 Free Software Foundation and other authors who decide to use it.  You
     50 can use it too, but we suggest you first think carefully about whether
     51 this license or the ordinary General Public License is the better
     52 strategy to use in any particular case, based on the explanations below.
     53 
     54   When we speak of free software, we are referring to freedom of use,
     55 not price.  Our General Public Licenses are designed to make sure that
     56 you have the freedom to distribute copies of free software (and charge
     57 for this service if you wish); that you receive source code or can get
     58 it if you want it; that you can change the software and use pieces of
     59 it in new free programs; and that you are informed that you can do
     60 these things.
     61 
     62   To protect your rights, we need to make restrictions that forbid
     63 distributors to deny you these rights or to ask you to surrender these
     64 rights.  These restrictions translate to certain responsibilities for
     65 you if you distribute copies of the library or if you modify it.
     66 
     67   For example, if you distribute copies of the library, whether gratis
     68 or for a fee, you must give the recipients all the rights that we gave
     69 you.  You must make sure that they, too, receive or can get the source
     70 code.  If you link other code with the library, you must provide
     71 complete object files to the recipients, so that they can relink them
     72 with the library after making changes to the library and recompiling
     73 it.  And you must show them these terms so they know their rights.
     74 
     75   We protect your rights with a two-step method: (1) we copyright the
     76 library, and (2) we offer you this license, which gives you legal
     77 permission to copy, distribute and/or modify the library.
     78 
     79   To protect each distributor, we want to make it very clear that
     80 there is no warranty for the free library.  Also, if the library is
     81 modified by someone else and passed on, the recipients should know
     82 that what they have is not the original version, so that the original
     83 author's reputation will not be affected by problems that might be
     84 introduced by others.
     85 
     86   Finally, software patents pose a constant threat to the existence of
     87 any free program.  We wish to make sure that a company cannot
     88 effectively restrict the users of a free program by obtaining a
     89 restrictive license from a patent holder.  Therefore, we insist that
     90 any patent license obtained for a version of the library must be
     91 consistent with the full freedom of use specified in this license.
     92 
     93   Most GNU software, including some libraries, is covered by the
     94 ordinary GNU General Public License.  This license, the GNU Lesser
     95 General Public License, applies to certain designated libraries, and
     96 is quite different from the ordinary General Public License.  We use
     97 this license for certain libraries in order to permit linking those
     98 libraries into non-free programs.
     99 
    100   When a program is linked with a library, whether statically or using
    101 a shared library, the combination of the two is legally speaking a
    102 combined work, a derivative of the original library.  The ordinary
    103 General Public License therefore permits such linking only if the
    104 entire combination fits its criteria of freedom.  The Lesser General
    105 Public License permits more lax criteria for linking other code with
    106 the library.
    107 
    108   We call this license the "Lesser" General Public License because it
    109 does Less to protect the user's freedom than the ordinary General
    110 Public License.  It also provides other free software developers Less
    111 of an advantage over competing non-free programs.  These disadvantages
    112 are the reason we use the ordinary General Public License for many
    113 libraries.  However, the Lesser license provides advantages in certain
    114 special circumstances.
    115 
    116   For example, on rare occasions, there may be a special need to
    117 encourage the widest possible use of a certain library, so that it becomes
    118 a de-facto standard.  To achieve this, non-free programs must be
    119 allowed to use the library.  A more frequent case is that a free
    120 library does the same job as widely used non-free libraries.  In this
    121 case, there is little to gain by limiting the free library to free
    122 software only, so we use the Lesser General Public License.
    123 
    124   In other cases, permission to use a particular library in non-free
    125 programs enables a greater number of people to use a large body of
    126 free software.  For example, permission to use the GNU C Library in
    127 non-free programs enables many more people to use the whole GNU
    128 operating system, as well as its variant, the GNU/Linux operating
    129 system.
    130 
    131   Although the Lesser General Public License is Less protective of the
    132 users' freedom, it does ensure that the user of a program that is
    133 linked with the Library has the freedom and the wherewithal to run
    134 that program using a modified version of the Library.
    135 
    136   The precise terms and conditions for copying, distribution and
    137 modification follow.  Pay close attention to the difference between a
    138 "work based on the library" and a "work that uses the library".  The
    139 former contains code derived from the library, whereas the latter must
    140 be combined with the library in order to run.
    141 
    142                   GNU LESSER GENERAL PUBLIC LICENSE
    143    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
    144 
    145   0. This License Agreement applies to any software library or other
    146 program which contains a notice placed by the copyright holder or
    147 other authorized party saying it may be distributed under the terms of
    148 this Lesser General Public License (also called "this License").
    149 Each licensee is addressed as "you".
    150 
    151   A "library" means a collection of software functions and/or data
    152 prepared so as to be conveniently linked with application programs
    153 (which use some of those functions and data) to form executables.
    154 
    155   The "Library", below, refers to any such software library or work
    156 which has been distributed under these terms.  A "work based on the
    157 Library" means either the Library or any derivative work under
    158 copyright law: that is to say, a work containing the Library or a
    159 portion of it, either verbatim or with modifications and/or translated
    160 straightforwardly into another language.  (Hereinafter, translation is
    161 included without limitation in the term "modification".)
    162 
    163   "Source code" for a work means the preferred form of the work for
    164 making modifications to it.  For a library, complete source code means
    165 all the source code for all modules it contains, plus any associated
    166 interface definition files, plus the scripts used to control compilation
    167 and installation of the library.
    168 
    169   Activities other than copying, distribution and modification are not
    170 covered by this License; they are outside its scope.  The act of
    171 running a program using the Library is not restricted, and output from
    172 such a program is covered only if its contents constitute a work based
    173 on the Library (independent of the use of the Library in a tool for
    174 writing it).  Whether that is true depends on what the Library does
    175 and what the program that uses the Library does.
    176 
    177   1. You may copy and distribute verbatim copies of the Library's
    178 complete source code as you receive it, in any medium, provided that
    179 you conspicuously and appropriately publish on each copy an
    180 appropriate copyright notice and disclaimer of warranty; keep intact
    181 all the notices that refer to this License and to the absence of any
    182 warranty; and distribute a copy of this License along with the
    183 Library.
    184 
    185   You may charge a fee for the physical act of transferring a copy,
    186 and you may at your option offer warranty protection in exchange for a
    187 fee.
    188 
    189   2. You may modify your copy or copies of the Library or any portion
    190 of it, thus forming a work based on the Library, and copy and
    191 distribute such modifications or work under the terms of Section 1
    192 above, provided that you also meet all of these conditions:
    193 
    194     a) The modified work must itself be a software library.
    195 
    196     b) You must cause the files modified to carry prominent notices
    197     stating that you changed the files and the date of any change.
    198 
    199     c) You must cause the whole of the work to be licensed at no
    200     charge to all third parties under the terms of this License.
    201 
    202     d) If a facility in the modified Library refers to a function or a
    203     table of data to be supplied by an application program that uses
    204     the facility, other than as an argument passed when the facility
    205     is invoked, then you must make a good faith effort to ensure that,
    206     in the event an application does not supply such function or
    207     table, the facility still operates, and performs whatever part of
    208     its purpose remains meaningful.
    209 
    210     (For example, a function in a library to compute square roots has
    211     a purpose that is entirely well-defined independent of the
    212     application.  Therefore, Subsection 2d requires that any
    213     application-supplied function or table used by this function must
    214     be optional: if the application does not supply it, the square
    215     root function must still compute square roots.)
    216 
    217 These requirements apply to the modified work as a whole.  If
    218 identifiable sections of that work are not derived from the Library,
    219 and can be reasonably considered independent and separate works in
    220 themselves, then this License, and its terms, do not apply to those
    221 sections when you distribute them as separate works.  But when you
    222 distribute the same sections as part of a whole which is a work based
    223 on the Library, the distribution of the whole must be on the terms of
    224 this License, whose permissions for other licensees extend to the
    225 entire whole, and thus to each and every part regardless of who wrote
    226 it.
    227 
    228 Thus, it is not the intent of this section to claim rights or contest
    229 your rights to work written entirely by you; rather, the intent is to
    230 exercise the right to control the distribution of derivative or
    231 collective works based on the Library.
    232 
    233 In addition, mere aggregation of another work not based on the Library
    234 with the Library (or with a work based on the Library) on a volume of
    235 a storage or distribution medium does not bring the other work under
    236 the scope of this License.
    237 
    238   3. You may opt to apply the terms of the ordinary GNU General Public
    239 License instead of this License to a given copy of the Library.  To do
    240 this, you must alter all the notices that refer to this License, so
    241 that they refer to the ordinary GNU General Public License, version 2,
    242 instead of to this License.  (If a newer version than version 2 of the
    243 ordinary GNU General Public License has appeared, then you can specify
    244 that version instead if you wish.)  Do not make any other change in
    245 these notices.
    246 
    247   Once this change is made in a given copy, it is irreversible for
    248 that copy, so the ordinary GNU General Public License applies to all
    249 subsequent copies and derivative works made from that copy.
    250 
    251   This option is useful when you wish to copy part of the code of
    252 the Library into a program that is not a library.
    253 
    254   4. You may copy and distribute the Library (or a portion or
    255 derivative of it, under Section 2) in object code or executable form
    256 under the terms of Sections 1 and 2 above provided that you accompany
    257 it with the complete corresponding machine-readable source code, which
    258 must be distributed under the terms of Sections 1 and 2 above on a
    259 medium customarily used for software interchange.
    260 
    261   If distribution of object code is made by offering access to copy
    262 from a designated place, then offering equivalent access to copy the
    263 source code from the same place satisfies the requirement to
    264 distribute the source code, even though third parties are not
    265 compelled to copy the source along with the object code.
    266 
    267   5. A program that contains no derivative of any portion of the
    268 Library, but is designed to work with the Library by being compiled or
    269 linked with it, is called a "work that uses the Library".  Such a
    270 work, in isolation, is not a derivative work of the Library, and
    271 therefore falls outside the scope of this License.
    272 
    273   However, linking a "work that uses the Library" with the Library
    274 creates an executable that is a derivative of the Library (because it
    275 contains portions of the Library), rather than a "work that uses the
    276 library".  The executable is therefore covered by this License.
    277 Section 6 states terms for distribution of such executables.
    278 
    279   When a "work that uses the Library" uses material from a header file
    280 that is part of the Library, the object code for the work may be a
    281 derivative work of the Library even though the source code is not.
    282 Whether this is true is especially significant if the work can be
    283 linked without the Library, or if the work is itself a library.  The
    284 threshold for this to be true is not precisely defined by law.
    285 
    286   If such an object file uses only numerical parameters, data
    287 structure layouts and accessors, and small macros and small inline
    288 functions (ten lines or less in length), then the use of the object
    289 file is unrestricted, regardless of whether it is legally a derivative
    290 work.  (Executables containing this object code plus portions of the
    291 Library will still fall under Section 6.)
    292 
    293   Otherwise, if the work is a derivative of the Library, you may
    294 distribute the object code for the work under the terms of Section 6.
    295 Any executables containing that work also fall under Section 6,
    296 whether or not they are linked directly with the Library itself.
    297 
    298   6. As an exception to the Sections above, you may also combine or
    299 link a "work that uses the Library" with the Library to produce a
    300 work containing portions of the Library, and distribute that work
    301 under terms of your choice, provided that the terms permit
    302 modification of the work for the customer's own use and reverse
    303 engineering for debugging such modifications.
    304 
    305   You must give prominent notice with each copy of the work that the
    306 Library is used in it and that the Library and its use are covered by
    307 this License.  You must supply a copy of this License.  If the work
    308 during execution displays copyright notices, you must include the
    309 copyright notice for the Library among them, as well as a reference
    310 directing the user to the copy of this License.  Also, you must do one
    311 of these things:
    312 
    313     a) Accompany the work with the complete corresponding
    314     machine-readable source code for the Library including whatever
    315     changes were used in the work (which must be distributed under
    316     Sections 1 and 2 above); and, if the work is an executable linked
    317     with the Library, with the complete machine-readable "work that
    318     uses the Library", as object code and/or source code, so that the
    319     user can modify the Library and then relink to produce a modified
    320     executable containing the modified Library.  (It is understood
    321     that the user who changes the contents of definitions files in the
    322     Library will not necessarily be able to recompile the application
    323     to use the modified definitions.)
    324 
    325     b) Use a suitable shared library mechanism for linking with the
    326     Library.  A suitable mechanism is one that (1) uses at run time a
    327     copy of the library already present on the user's computer system,
    328     rather than copying library functions into the executable, and (2)
    329     will operate properly with a modified version of the library, if
    330     the user installs one, as long as the modified version is
    331     interface-compatible with the version that the work was made with.
    332 
    333     c) Accompany the work with a written offer, valid for at
    334     least three years, to give the same user the materials
    335     specified in Subsection 6a, above, for a charge no more
    336     than the cost of performing this distribution.
    337 
    338     d) If distribution of the work is made by offering access to copy
    339     from a designated place, offer equivalent access to copy the above
    340     specified materials from the same place.
    341 
    342     e) Verify that the user has already received a copy of these
    343     materials or that you have already sent this user a copy.
    344 
    345   For an executable, the required form of the "work that uses the
    346 Library" must include any data and utility programs needed for
    347 reproducing the executable from it.  However, as a special exception,
    348 the materials to be distributed need not include anything that is
    349 normally distributed (in either source or binary form) with the major
    350 components (compiler, kernel, and so on) of the operating system on
    351 which the executable runs, unless that component itself accompanies
    352 the executable.
    353 
    354   It may happen that this requirement contradicts the license
    355 restrictions of other proprietary libraries that do not normally
    356 accompany the operating system.  Such a contradiction means you cannot
    357 use both them and the Library together in an executable that you
    358 distribute.
    359 
    360   7. You may place library facilities that are a work based on the
    361 Library side-by-side in a single library together with other library
    362 facilities not covered by this License, and distribute such a combined
    363 library, provided that the separate distribution of the work based on
    364 the Library and of the other library facilities is otherwise
    365 permitted, and provided that you do these two things:
    366 
    367     a) Accompany the combined library with a copy of the same work
    368     based on the Library, uncombined with any other library
    369     facilities.  This must be distributed under the terms of the
    370     Sections above.
    371 
    372     b) Give prominent notice with the combined library of the fact
    373     that part of it is a work based on the Library, and explaining
    374     where to find the accompanying uncombined form of the same work.
    375 
    376   8. You may not copy, modify, sublicense, link with, or distribute
    377 the Library except as expressly provided under this License.  Any
    378 attempt otherwise to copy, modify, sublicense, link with, or
    379 distribute the Library is void, and will automatically terminate your
    380 rights under this License.  However, parties who have received copies,
    381 or rights, from you under this License will not have their licenses
    382 terminated so long as such parties remain in full compliance.
    383 
    384   9. You are not required to accept this License, since you have not
    385 signed it.  However, nothing else grants you permission to modify or
    386 distribute the Library or its derivative works.  These actions are
    387 prohibited by law if you do not accept this License.  Therefore, by
    388 modifying or distributing the Library (or any work based on the
    389 Library), you indicate your acceptance of this License to do so, and
    390 all its terms and conditions for copying, distributing or modifying
    391 the Library or works based on it.
    392 
    393   10. Each time you redistribute the Library (or any work based on the
    394 Library), the recipient automatically receives a license from the
    395 original licensor to copy, distribute, link with or modify the Library
    396 subject to these terms and conditions.  You may not impose any further
    397 restrictions on the recipients' exercise of the rights granted herein.
    398 You are not responsible for enforcing compliance by third parties with
    399 this License.
    400 
    401   11. If, as a consequence of a court judgment or allegation of patent
    402 infringement or for any other reason (not limited to patent issues),
    403 conditions are imposed on you (whether by court order, agreement or
    404 otherwise) that contradict the conditions of this License, they do not
    405 excuse you from the conditions of this License.  If you cannot
    406 distribute so as to satisfy simultaneously your obligations under this
    407 License and any other pertinent obligations, then as a consequence you
    408 may not distribute the Library at all.  For example, if a patent
    409 license would not permit royalty-free redistribution of the Library by
    410 all those who receive copies directly or indirectly through you, then
    411 the only way you could satisfy both it and this License would be to
    412 refrain entirely from distribution of the Library.
    413 
    414 If any portion of this section is held invalid or unenforceable under any
    415 particular circumstance, the balance of the section is intended to apply,
    416 and the section as a whole is intended to apply in other circumstances.
    417 
    418 It is not the purpose of this section to induce you to infringe any
    419 patents or other property right claims or to contest validity of any
    420 such claims; this section has the sole purpose of protecting the
    421 integrity of the free software distribution system which is
    422 implemented by public license practices.  Many people have made
    423 generous contributions to the wide range of software distributed
    424 through that system in reliance on consistent application of that
    425 system; it is up to the author/donor to decide if he or she is willing
    426 to distribute software through any other system and a licensee cannot
    427 impose that choice.
    428 
    429 This section is intended to make thoroughly clear what is believed to
    430 be a consequence of the rest of this License.
    431 
    432   12. If the distribution and/or use of the Library is restricted in
    433 certain countries either by patents or by copyrighted interfaces, the
    434 original copyright holder who places the Library under this License may add
    435 an explicit geographical distribution limitation excluding those countries,
    436 so that distribution is permitted only in or among countries not thus
    437 excluded.  In such case, this License incorporates the limitation as if
    438 written in the body of this License.
    439 
    440   13. The Free Software Foundation may publish revised and/or new
    441 versions of the Lesser General Public License from time to time.
    442 Such new versions will be similar in spirit to the present version,
    443 but may differ in detail to address new problems or concerns.
    444 
    445 Each version is given a distinguishing version number.  If the Library
    446 specifies a version number of this License which applies to it and
    447 "any later version", you have the option of following the terms and
    448 conditions either of that version or of any later version published by
    449 the Free Software Foundation.  If the Library does not specify a
    450 license version number, you may choose any version ever published by
    451 the Free Software Foundation.
    452 
    453   14. If you wish to incorporate parts of the Library into other free
    454 programs whose distribution conditions are incompatible with these,
    455 write to the author to ask for permission.  For software which is
    456 copyrighted by the Free Software Foundation, write to the Free
    457 Software Foundation; we sometimes make exceptions for this.  Our
    458 decision will be guided by the two goals of preserving the free status
    459 of all derivatives of our free software and of promoting the sharing
    460 and reuse of software generally.
    461 
    462                             NO WARRANTY
    463 
    464   15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
    465 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
    466 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
    467 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
    468 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
    469 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
    470 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
    471 LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
    472 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
    473 
    474   16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
    475 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
    476 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
    477 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
    478 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
    479 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
    480 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
    481 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
    482 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
    483 DAMAGES.

    492                     GNU GENERAL PUBLIC LICENSE
    493                        Version 2, June 1991
    494 
    495  Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
    496  <https://fsf.org/>
    497  Everyone is permitted to copy and distribute verbatim copies
    498  of this license document, but changing it is not allowed.
    499 
    500                             Preamble
    501 
    502   The licenses for most software are designed to take away your
    503 freedom to share and change it.  By contrast, the GNU General Public
    504 License is intended to guarantee your freedom to share and change free
    505 software--to make sure the software is free for all its users.  This
    506 General Public License applies to most of the Free Software
    507 Foundation's software and to any other program whose authors commit to
    508 using it.  (Some other Free Software Foundation software is covered by
    509 the GNU Lesser General Public License instead.)  You can apply it to
    510 your programs, too.
    511 
    512   When we speak of free software, we are referring to freedom, not
    513 price.  Our General Public Licenses are designed to make sure that you
    514 have the freedom to distribute copies of free software (and charge for
    515 this service if you wish), that you receive source code or can get it
    516 if you want it, that you can change the software or use pieces of it
    517 in new free programs; and that you know you can do these things.
    518 
    519   To protect your rights, we need to make restrictions that forbid
    520 anyone to deny you these rights or to ask you to surrender the rights.
    521 These restrictions translate to certain responsibilities for you if you
    522 distribute copies of the software, or if you modify it.
    523 
    524   For example, if you distribute copies of such a program, whether
    525 gratis or for a fee, you must give the recipients all the rights that
    526 you have.  You must make sure that they, too, receive or can get the
    527 source code.  And you must show them these terms so they know their
    528 rights.
    529 
    530   We protect your rights with two steps: (1) copyright the software, and
    531 (2) offer you this license which gives you legal permission to copy,
    532 distribute and/or modify the software.
    533 
    534   Also, for each author's protection and ours, we want to make certain
    535 that everyone understands that there is no warranty for this free
    536 software.  If the software is modified by someone else and passed on, we
    537 want its recipients to know that what they have is not the original, so
    538 that any problems introduced by others will not reflect on the original
    539 authors' reputations.
    540 
    541   Finally, any free program is threatened constantly by software
    542 patents.  We wish to avoid the danger that redistributors of a free
    543 program will individually obtain patent licenses, in effect making the
    544 program proprietary.  To prevent this, we have made it clear that any
    545 patent must be licensed for everyone's free use or not licensed at all.
    546 
    547   The precise terms and conditions for copying, distribution and
    548 modification follow.
    549 
    550                     GNU GENERAL PUBLIC LICENSE
    551    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
    552 
    553   0. This License applies to any program or other work which contains
    554 a notice placed by the copyright holder saying it may be distributed
    555 under the terms of this General Public License.  The "Program", below,
    556 refers to any such program or work, and a "work based on the Program"
    557 means either the Program or any derivative work under copyright law:
    558 that is to say, a work containing the Program or a portion of it,
    559 either verbatim or with modifications and/or translated into another
    560 language.  (Hereinafter, translation is included without limitation in
    561 the term "modification".)  Each licensee is addressed as "you".
    562 
    563 Activities other than copying, distribution and modification are not
    564 covered by this License; they are outside its scope.  The act of
    565 running the Program is not restricted, and the output from the Program
    566 is covered only if its contents constitute a work based on the
    567 Program (independent of having been made by running the Program).
    568 Whether that is true depends on what the Program does.
    569 
    570   1. You may copy and distribute verbatim copies of the Program's
    571 source code as you receive it, in any medium, provided that you
    572 conspicuously and appropriately publish on each copy an appropriate
    573 copyright notice and disclaimer of warranty; keep intact all the
    574 notices that refer to this License and to the absence of any warranty;
    575 and give any other recipients of the Program a copy of this License
    576 along with the Program.
    577 
    578 You may charge a fee for the physical act of transferring a copy, and
    579 you may at your option offer warranty protection in exchange for a fee.
    580 
    581   2. You may modify your copy or copies of the Program or any portion
    582 of it, thus forming a work based on the Program, and copy and
    583 distribute such modifications or work under the terms of Section 1
    584 above, provided that you also meet all of these conditions:
    585 
    586     a) You must cause the modified files to carry prominent notices
    587     stating that you changed the files and the date of any change.
    588 
    589     b) You must cause any work that you distribute or publish, that in
    590     whole or in part contains or is derived from the Program or any
    591     part thereof, to be licensed as a whole at no charge to all third
    592     parties under the terms of this License.
    593 
    594     c) If the modified program normally reads commands interactively
    595     when run, you must cause it, when started running for such
    596     interactive use in the most ordinary way, to print or display an
    597     announcement including an appropriate copyright notice and a
    598     notice that there is no warranty (or else, saying that you provide
    599     a warranty) and that users may redistribute the program under
    600     these conditions, and telling the user how to view a copy of this
    601     License.  (Exception: if the Program itself is interactive but
    602     does not normally print such an announcement, your work based on
    603     the Program is not required to print an announcement.)
    604 
    605 These requirements apply to the modified work as a whole.  If
    606 identifiable sections of that work are not derived from the Program,
    607 and can be reasonably considered independent and separate works in
    608 themselves, then this License, and its terms, do not apply to those
    609 sections when you distribute them as separate works.  But when you
    610 distribute the same sections as part of a whole which is a work based
    611 on the Program, the distribution of the whole must be on the terms of
    612 this License, whose permissions for other licensees extend to the
    613 entire whole, and thus to each and every part regardless of who wrote it.
    614 
    615 Thus, it is not the intent of this section to claim rights or contest
    616 your rights to work written entirely by you; rather, the intent is to
    617 exercise the right to control the distribution of derivative or
    618 collective works based on the Program.
    619 
    620 In addition, mere aggregation of another work not based on the Program
    621 with the Program (or with a work based on the Program) on a volume of
    622 a storage or distribution medium does not bring the other work under
    623 the scope of this License.
    624 
    625   3. You may copy and distribute the Program (or a work based on it,
    626 under Section 2) in object code or executable form under the terms of
    627 Sections 1 and 2 above provided that you also do one of the following:
    628 
    629     a) Accompany it with the complete corresponding machine-readable
    630     source code, which must be distributed under the terms of Sections
    631     1 and 2 above on a medium customarily used for software interchange; or,
    632 
    633     b) Accompany it with a written offer, valid for at least three
    634     years, to give any third party, for a charge no more than your
    635     cost of physically performing source distribution, a complete
    636     machine-readable copy of the corresponding source code, to be
    637     distributed under the terms of Sections 1 and 2 above on a medium
    638     customarily used for software interchange; or,
    639 
    640     c) Accompany it with the information you received as to the offer
    641     to distribute corresponding source code.  (This alternative is
    642     allowed only for noncommercial distribution and only if you
    643     received the program in object code or executable form with such
    644     an offer, in accord with Subsection b above.)
    645 
    646 The source code for a work means the preferred form of the work for
    647 making modifications to it.  For an executable work, complete source
    648 code means all the source code for all modules it contains, plus any
    649 associated interface definition files, plus the scripts used to
    650 control compilation and installation of the executable.  However, as a
    651 special exception, the source code distributed need not include
    652 anything that is normally distributed (in either source or binary
    653 form) with the major components (compiler, kernel, and so on) of the
    654 operating system on which the executable runs, unless that component
    655 itself accompanies the executable.
    656 
    657 If distribution of executable or object code is made by offering
    658 access to copy from a designated place, then offering equivalent
    659 access to copy the source code from the same place counts as
    660 distribution of the source code, even though third parties are not
    661 compelled to copy the source along with the object code.
    662 
    663   4. You may not copy, modify, sublicense, or distribute the Program
    664 except as expressly provided under this License.  Any attempt
    665 otherwise to copy, modify, sublicense or distribute the Program is
    666 void, and will automatically terminate your rights under this License.
    667 However, parties who have received copies, or rights, from you under
    668 this License will not have their licenses terminated so long as such
    669 parties remain in full compliance.
    670 
    671   5. You are not required to accept this License, since you have not
    672 signed it.  However, nothing else grants you permission to modify or
    673 distribute the Program or its derivative works.  These actions are
    674 prohibited by law if you do not accept this License.  Therefore, by
    675 modifying or distributing the Program (or any work based on the
    676 Program), you indicate your acceptance of this License to do so, and
    677 all its terms and conditions for copying, distributing or modifying
    678 the Program or works based on it.
    679 
    680   6. Each time you redistribute the Program (or any work based on the
    681 Program), the recipient automatically receives a license from the
    682 original licensor to copy, distribute or modify the Program subject to
    683 these terms and conditions.  You may not impose any further
    684 restrictions on the recipients' exercise of the rights granted herein.
    685 You are not responsible for enforcing compliance by third parties to
    686 this License.
    687 
    688   7. If, as a consequence of a court judgment or allegation of patent
    689 infringement or for any other reason (not limited to patent issues),
    690 conditions are imposed on you (whether by court order, agreement or
    691 otherwise) that contradict the conditions of this License, they do not
    692 excuse you from the conditions of this License.  If you cannot
    693 distribute so as to satisfy simultaneously your obligations under this
    694 License and any other pertinent obligations, then as a consequence you
    695 may not distribute the Program at all.  For example, if a patent
    696 license would not permit royalty-free redistribution of the Program by
    697 all those who receive copies directly or indirectly through you, then
    698 the only way you could satisfy both it and this License would be to
    699 refrain entirely from distribution of the Program.
    700 
    701 If any portion of this section is held invalid or unenforceable under
    702 any particular circumstance, the balance of the section is intended to
    703 apply and the section as a whole is intended to apply in other
    704 circumstances.
    705 
    706 It is not the purpose of this section to induce you to infringe any
    707 patents or other property right claims or to contest validity of any
    708 such claims; this section has the sole purpose of protecting the
    709 integrity of the free software distribution system, which is
    710 implemented by public license practices.  Many people have made
    711 generous contributions to the wide range of software distributed
    712 through that system in reliance on consistent application of that
    713 system; it is up to the author/donor to decide if he or she is willing
    714 to distribute software through any other system and a licensee cannot
    715 impose that choice.
    716 
    717 This section is intended to make thoroughly clear what is believed to
    718 be a consequence of the rest of this License.
    719 
    720   8. If the distribution and/or use of the Program is restricted in
    721 certain countries either by patents or by copyrighted interfaces, the
    722 original copyright holder who places the Program under this License
    723 may add an explicit geographical distribution limitation excluding
    724 those countries, so that distribution is permitted only in or among
    725 countries not thus excluded.  In such case, this License incorporates
    726 the limitation as if written in the body of this License.
    727 
    728   9. The Free Software Foundation may publish revised and/or new versions
    729 of the General Public License from time to time.  Such new versions will
    730 be similar in spirit to the present version, but may differ in detail to
    731 address new problems or concerns.
    732 
    733 Each version is given a distinguishing version number.  If the Program
    734 specifies a version number of this License which applies to it and "any
    735 later version", you have the option of following the terms and conditions
    736 either of that version or of any later version published by the Free
    737 Software Foundation.  If the Program does not specify a version number of
    738 this License, you may choose any version ever published by the Free Software
    739 Foundation.
    740 
    741   10. If you wish to incorporate parts of the Program into other free
    742 programs whose distribution conditions are different, write to the author
    743 to ask for permission.  For software which is copyrighted by the Free
    744 Software Foundation, write to the Free Software Foundation; we sometimes
    745 make exceptions for this.  Our decision will be guided by the two goals
    746 of preserving the free status of all derivatives of our free software and
    747 of promoting the sharing and reuse of software generally.
    748 
    749                             NO WARRANTY
    750 
    751   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
    752 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
    753 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
    754 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
    755 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
    756 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
    757 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
    758 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
    759 REPAIR OR CORRECTION.
    760 
    761   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
    762 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
    763 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
    764 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
    765 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
    766 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
    767 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
    768 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
    769 POSSIBILITY OF SUCH DAMAGES.
    770 
    771             SPECIAL EXCEPTION (eCos Exception, version 2.0)
    772 
    773 This section constitutes an additional permission under the GNU General
    774 Public License, version 2 or any later version.
    775 
    776 As a special exception, if other files instantiate templates or use
    777 macros or inline functions from the Program, or you compile the
    778 Program and link it with other works to produce a work based on the
    779 Program, the Program does not by itself cause the resulting work to
    780 be covered by the GNU General Public License. However the source
    781 code for the Program must still be made available in accordance with
    782 section (3) of the GNU General Public License v2.
    783 
    784 This exception does not invalidate any other reasons why a work based
    785 on the Program might be covered by the GNU General Public License.
    786
