                      6:  Everyone is permitted to copy and distribute verbatim copies
                      7:  of this license document, but changing it is not allowed.
                      8: 
                      9: [This is the first released version of the library GPL.  It is
                     10:  numbered 2 because it goes with version 2 of the ordinary GPL.]
                     11: 
                     12:                            Preamble
                     13: 
                     14:   The licenses for most software are designed to take away your
                     15: freedom to share and change it.  By contrast, the GNU General Public
                     16: Licenses are intended to guarantee your freedom to share and change
                     17: free software--to make sure the software is free for all its users.
                     18: 
                     19:   This license, the Library General Public License, applies to some
                     20: specially designated Free Software Foundation software, and to any
                     21: other libraries whose authors decide to use it.  You can use it for
                     22: your libraries, 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: this service if you wish), that you receive source code or can get it
                     28: if you want it, that you can change the software or use pieces of it
                     29: in new free programs; and that you know you can do these things.
                     30: 
                     31:   To protect your rights, we need to make restrictions that forbid
                     32: anyone to deny you these rights or to ask you to surrender the rights.
                     33: These restrictions translate to certain responsibilities for you if
                     34: you distribute copies of the library, or if you modify it.
                     35: 
                     36:   For example, if you distribute copies of the library, whether gratis
                     37: or for a fee, you must give the recipients all the rights that we gave
                     38: you.  You must make sure that they, too, receive or can get the source
                     39: code.  If you link a program with the library, you must provide
                     40: complete object files to the recipients so that they can relink them
                     41: with the library, after making changes to the library and recompiling
                     42: it.  And you must show them these terms so they know their rights.
                     43: 
                     44:   Our method of protecting your rights has two steps: (1) copyright
                     45: the library, and (2) offer you this license which gives you legal
                     46: permission to copy, distribute and/or modify the library.
                     47: 
                     48:   Also, for each distributor's protection, we want to make certain
                     49: that everyone understands that there is no warranty for this free
                     50: library.  If the library is modified by someone else and passed on, we
                     51: want its recipients to know that what they have is not the original
                     52: version, so that any problems introduced by others will not reflect on
                     53: the original authors' reputations.
                     54: 
                     55:   Finally, any free program is threatened constantly by software
                     56: patents.  We wish to avoid the danger that companies distributing free
                     57: software will individually obtain patent licenses, thus in effect
                     58: transforming the program into proprietary software.  To prevent this,
                     59: we have made it clear that any patent must be licensed for everyone's
                     60: free use or not licensed at all.
                     61: 
                     62:   Most GNU software, including some libraries, is covered by the ordinary
                     63: GNU General Public License, which was designed for utility programs.  This
                     64: license, the GNU Library General Public License, applies to certain
                     65: designated libraries.  This license is quite different from the ordinary
                     66: one; be sure to read it in full, and don't assume that anything in it is
                     67: the same as in the ordinary license.
                     68: 
                     69:   The reason we have a separate public license for some libraries is that
                     70: they blur the distinction we usually make between modifying or adding to a
                     71: program and simply using it.  Linking a program with a library, without
                     72: changing the library, is in some sense simply using the library, and is
                     73: analogous to running a utility program or application program.  However, in
                     74: a textual and legal sense, the linked executable is a combined work, a
                     75: derivative of the original library, and the ordinary General Public License
                     76: treats it as such.
                     77: 
                     78:   Because of this blurred distinction, using the ordinary General
                     79: Public License for libraries did not effectively promote software
                     80: sharing, because most developers did not use the libraries.  We
                     81: concluded that weaker conditions might promote sharing better.
                     82: 
                     83:   However, unrestricted linking of non-free programs would deprive the
                     84: users of those programs of all benefit from the free status of the
                     85: libraries themselves.  This Library General Public License is intended to
                     86: permit developers of non-free programs to use free libraries, while
                     87: preserving your freedom as a user of such programs to change the free
                     88: libraries that are incorporated in them.  (We have not seen how to achieve
                     89: this as regards changes in header files, but we have achieved it as regards
                     90: changes in the actual functions of the Library.)  The hope is that this
                     91: will lead to faster development of free libraries.
                     92: 
                     93:   The precise terms and conditions for copying, distribution and
                     94: modification follow.  Pay close attention to the difference between a
                     95: "work based on the library" and a "work that uses the library".  The
                     96: former contains code derived from the library, while the latter only
                     97: works together with the library.
                     98: 
                     99:   Note that it is possible for a library to be covered by the ordinary
                    100: General Public License rather than by this special one.
                    101: 
                    102:                  GNU LIBRARY GENERAL PUBLIC LICENSE
                    103:    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
                    104: 
                    105:   0. This License Agreement applies to any software library which
                    106: contains a notice placed by the copyright holder or other authorized
                    107: party saying it may be distributed under the terms of this Library
                    108: General Public License (also called "this License").  Each licensee is
                    109: addressed as "you".
                    110: 
                    111:   A "library" means a collection of software functions and/or data
                    112: prepared so as to be conveniently linked with application programs
                    113: (which use some of those functions and data) to form executables.
                    114: 
                    115:   The "Library", below, refers to any such software library or work
                    116: which has been distributed under these terms.  A "work based on the
                    117: Library" means either the Library or any derivative work under
                    118: copyright law: that is to say, a work containing the Library or a
                    119: portion of it, either verbatim or with modifications and/or translated
                    120: straightforwardly into another language.  (Hereinafter, translation is
                    121: included without limitation in the term "modification".)
                    122: 
                    123:   "Source code" for a work means the preferred form of the work for
                    124: making modifications to it.  For a library, complete source code means
                    125: all the source code for all modules it contains, plus any associated
                    126: interface definition files, plus the scripts used to control compilation
                    127: and installation of the library.
                    128: 
                    129:   Activities other than copying, distribution and modification are not
                    130: covered by this License; they are outside its scope.  The act of
                    131: running a program using the Library is not restricted, and output from
                    132: such a program is covered only if its contents constitute a work based
                    133: on the Library (independent of the use of the Library in a tool for
                    134: writing it).  Whether that is true depends on what the Library does
                    135: and what the program that uses the Library does.
                    136:   
                    137:   1. You may copy and distribute verbatim copies of the Library's
                    138: complete source code as you receive it, in any medium, provided that
                    139: you conspicuously and appropriately publish on each copy an
                    140: appropriate copyright notice and disclaimer of warranty; keep intact
                    141: all the notices that refer to this License and to the absence of any
                    142: warranty; and distribute a copy of this License along with the
                    143: Library.
                    144: 
                    145:   You may charge a fee for the physical act of transferring a copy,
                    146: and you may at your option offer warranty protection in exchange for a
                    147: fee.
                    148: 
                    149:   2. You may modify your copy or copies of the Library or any portion
                    150: of it, thus forming a work based on the Library, and copy and
                    151: distribute such modifications or work under the terms of Section 1
                    152: above, provided that you also meet all of these conditions:
                    153: 
                    154:     a) The modified work must itself be a software library.
                    155: 
                    156:     b) You must cause the files modified to carry prominent notices
                    157:     stating that you changed the files and the date of any change.
                    158: 
                    159:     c) You must cause the whole of the work to be licensed at no
                    160:     charge to all third parties under the terms of this License.
                    161: 
                    162:     d) If a facility in the modified Library refers to a function or a
                    163:     table of data to be supplied by an application program that uses
                    164:     the facility, other than as an argument passed when the facility
                    165:     is invoked, then you must make a good faith effort to ensure that,
                    166:     in the event an application does not supply such function or
                    167:     table, the facility still operates, and performs whatever part of
                    168:     its purpose remains meaningful.
                    169: 
                    170:     (For example, a function in a library to compute square roots has
                    171:     a purpose that is entirely well-defined independent of the
                    172:     application.  Therefore, Subsection 2d requires that any
                    173:     application-supplied function or table used by this function must
                    174:     be optional: if the application does not supply it, the square
                    175:     root function must still compute square roots.)
                    176: 
                    177: These requirements apply to the modified work as a whole.  If
                    178: identifiable sections of that work are not derived from the Library,
                    179: and can be reasonably considered independent and separate works in
                    180: themselves, then this License, and its terms, do not apply to those
                    181: sections when you distribute them as separate works.  But when you
                    182: distribute the same sections as part of a whole which is a work based
                    183: on the Library, the distribution of the whole must be on the terms of
                    184: this License, whose permissions for other licensees extend to the
                    185: entire whole, and thus to each and every part regardless of who wrote
                    186: it.
                    187: 
                    188: Thus, it is not the intent of this section to claim rights or contest
                    189: your rights to work written entirely by you; rather, the intent is to
                    190: exercise the right to control the distribution of derivative or
                    191: collective works based on the Library.
                    192: 
                    193: In addition, mere aggregation of another work not based on the Library
                    194: with the Library (or with a work based on the Library) on a volume of
                    195: a storage or distribution medium does not bring the other work under
                    196: the scope of this License.
                    197: 
                    198:   3. You may opt to apply the terms of the ordinary GNU General Public
                    199: License instead of this License to a given copy of the Library.  To do
                    200: this, you must alter all the notices that refer to this License, so
                    201: that they refer to the ordinary GNU General Public License, version 2,
                    202: instead of to this License.  (If a newer version than version 2 of the
                    203: ordinary GNU General Public License has appeared, then you can specify
                    204: that version instead if you wish.)  Do not make any other change in
                    205: these notices.
                    206: 
                    207:   Once this change is made in a given copy, it is irreversible for
                    208: that copy, so the ordinary GNU General Public License applies to all
                    209: subsequent copies and derivative works made from that copy.
                    210: 
                    211:   This option is useful when you wish to copy part of the code of
                    212: the Library into a program that is not a library.
                    213: 
                    214:   4. You may copy and distribute the Library (or a portion or
                    215: derivative of it, under Section 2) in object code or executable form
                    216: under the terms of Sections 1 and 2 above provided that you accompany
                    217: it with the complete corresponding machine-readable source code, which
                    218: must be distributed under the terms of Sections 1 and 2 above on a
                    219: medium customarily used for software interchange.
                    220: 
                    221:   If distribution of object code is made by offering access to copy
                    222: from a designated place, then offering equivalent access to copy the
                    223: source code from the same place satisfies the requirement to
                    224: distribute the source code, even though third parties are not
                    225: compelled to copy the source along with the object code.
                    226: 
                    227:   5. A program that contains no derivative of any portion of the
                    228: Library, but is designed to work with the Library by being compiled or
                    229: linked with it, is called a "work that uses the Library".  Such a
                    230: work, in isolation, is not a derivative work of the Library, and
                    231: therefore falls outside the scope of this License.
                    232: 
                    233:   However, linking a "work that uses the Library" with the Library
                    234: creates an executable that is a derivative of the Library (because it
                    235: contains portions of the Library), rather than a "work that uses the
                    236: library".  The executable is therefore covered by this License.
                    237: Section 6 states terms for distribution of such executables.
                    238: 
                    239:   When a "work that uses the Library" uses material from a header file
                    240: that is part of the Library, the object code for the work may be a
                    241: derivative work of the Library even though the source code is not.
                    242: Whether this is true is especially significant if the work can be
                    243: linked without the Library, or if the work is itself a library.  The
                    244: threshold for this to be true is not precisely defined by law.
                    245: 
                    246:   If such an object file uses only numerical parameters, data
                    247: structure layouts and accessors, and small macros and small inline
                    248: functions (ten lines or less in length), then the use of the object
                    249: file is unrestricted, regardless of whether it is legally a derivative
                    250: work.  (Executables containing this object code plus portions of the
                    251: Library will still fall under Section 6.)
                    252: 
                    253:   Otherwise, if the work is a derivative of the Library, you may
                    254: distribute the object code for the work under the terms of Section 6.
                    255: Any executables containing that work also fall under Section 6,
                    256: whether or not they are linked directly with the Library itself.
                    257: 
                    258:   6. As an exception to the Sections above, you may also compile or
                    259: link a "work that uses the Library" with the Library to produce a
                    260: work containing portions of the Library, and distribute that work
                    261: under terms of your choice, provided that the terms permit
                    262: modification of the work for the customer's own use and reverse
                    263: engineering for debugging such modifications.
                    264: 
                    265:   You must give prominent notice with each copy of the work that the
                    266: Library is used in it and that the Library and its use are covered by
                    267: this License.  You must supply a copy of this License.  If the work
                    268: during execution displays copyright notices, you must include the
                    269: copyright notice for the Library among them, as well as a reference
                    270: directing the user to the copy of this License.  Also, you must do one
                    271: of these things:
                    272: 
                    273:     a) Accompany the work with the complete corresponding
                    274:     machine-readable source code for the Library including whatever
                    275:     changes were used in the work (which must be distributed under
                    276:     Sections 1 and 2 above); and, if the work is an executable linked
                    277:     with the Library, with the complete machine-readable "work that
                    278:     uses the Library", as object code and/or source code, so that the
                    279:     user can modify the Library and then relink to produce a modified
                    280:     executable containing the modified Library.  (It is understood
                    281:     that the user who changes the contents of definitions files in the
                    282:     Library will not necessarily be able to recompile the application
                    283:     to use the modified definitions.)
                    284: 
                    285:     b) Accompany the work with a written offer, valid for at
                    286:     least three years, to give the same user the materials
                    287:     specified in Subsection 6a, above, for a charge no more
                    288:     than the cost of performing this distribution.
                    289: 
                    290:     c) If distribution of the work is made by offering access to copy
                    291:     from a designated place, offer equivalent access to copy the above
                    292:     specified materials from the same place.
                    293: 
                    294:     d) Verify that the user has already received a copy of these
                    295:     materials or that you have already sent this user a copy.
                    296: 
                    297:   For an executable, the required form of the "work that uses the
                    298: Library" must include any data and utility programs needed for
                    299: reproducing the executable from it.  However, as a special exception,
                    300: the source code distributed need not include anything that is normally
                    301: distributed (in either source or binary form) with the major
                    302: components (compiler, kernel, and so on) of the operating system on
                    303: which the executable runs, unless that component itself accompanies
                    304: the executable.
                    305: 
                    306:   It may happen that this requirement contradicts the license
                    307: restrictions of other proprietary libraries that do not normally
                    308: accompany the operating system.  Such a contradiction means you cannot
                    309: use both them and the Library together in an executable that you
                    310: distribute.
                    311: 
                    312:   7. You may place library facilities that are a work based on the
                    313: Library side-by-side in a single library together with other library
                    314: facilities not covered by this License, and distribute such a combined
                    315: library, provided that the separate distribution of the work based on
                    316: the Library and of the other library facilities is otherwise
                    317: permitted, and provided that you do these two things:
                    318: 
                    319:     a) Accompany the combined library with a copy of the same work
                    320:     based on the Library, uncombined with any other library
                    321:     facilities.  This must be distributed under the terms of the
                    322:     Sections above.
                    323: 
                    324:     b) Give prominent notice with the combined library of the fact
                    325:     that part of it is a work based on the Library, and explaining
                    326:     where to find the accompanying uncombined form of the same work.
                    327: 
                    328:   8. You may not copy, modify, sublicense, link with, or distribute
                    329: the Library except as expressly provided under this License.  Any
                    330: attempt otherwise to copy, modify, sublicense, link with, or
                    331: distribute the Library is void, and will automatically terminate your
                    332: rights under this License.  However, parties who have received copies,
                    333: or rights, from you under this License will not have their licenses
                    334: terminated so long as such parties remain in full compliance.
                    335: 
                    336:   9. You are not required to accept this License, since you have not
                    337: signed it.  However, nothing else grants you permission to modify or
                    338: distribute the Library or its derivative works.  These actions are
                    339: prohibited by law if you do not accept this License.  Therefore, by
                    340: modifying or distributing the Library (or any work based on the
                    341: Library), you indicate your acceptance of this License to do so, and
                    342: all its terms and conditions for copying, distributing or modifying
                    343: the Library or works based on it.
                    344: 
                    345:   10. Each time you redistribute the Library (or any work based on the
                    346: Library), the recipient automatically receives a license from the
                    347: original licensor to copy, distribute, link with or modify the Library
                    348: subject to these terms and conditions.  You may not impose any further
                    349: restrictions on the recipients' exercise of the rights granted herein.
                    350: You are not responsible for enforcing compliance by third parties to
                    351: this License.
                    352: 
                    353:   11. If, as a consequence of a court judgment or allegation of patent
                    354: infringement or for any other reason (not limited to patent issues),
                    355: conditions are imposed on you (whether by court order, agreement or
                    356: otherwise) that contradict the conditions of this License, they do not
                    357: excuse you from the conditions of this License.  If you cannot
                    358: distribute so as to satisfy simultaneously your obligations under this
                    359: License and any other pertinent obligations, then as a consequence you
                    360: may not distribute the Library at all.  For example, if a patent
                    361: license would not permit royalty-free redistribution of the Library by
                    362: all those who receive copies directly or indirectly through you, then
                    363: the only way you could satisfy both it and this License would be to
                    364: refrain entirely from distribution of the Library.
                    365: 
                    366: If any portion of this section is held invalid or unenforceable under any
                    367: particular circumstance, the balance of the section is intended to apply,
                    368: and the section as a whole is intended to apply in other circumstances.
                    369: 
                    370: It is not the purpose of this section to induce you to infringe any
                    371: patents or other property right claims or to contest validity of any
                    372: such claims; this section has the sole purpose of protecting the
                    373: integrity of the free software distribution system which is
                    374: implemented by public license practices.  Many people have made
                    375: generous contributions to the wide range of software distributed
                    376: through that system in reliance on consistent application of that
                    377: system; it is up to the author/donor to decide if he or she is willing
                    378: to distribute software through any other system and a licensee cannot
                    379: impose that choice.
                    380: 
                    381: This section is intended to make thoroughly clear what is believed to
                    382: be a consequence of the rest of this License.
                    383: 
                    384:   12. If the distribution and/or use of the Library is restricted in
                    385: certain countries either by patents or by copyrighted interfaces, the
                    386: original copyright holder who places the Library under this License may add
                    387: an explicit geographical distribution limitation excluding those countries,
                    388: so that distribution is permitted only in or among countries not thus
                    389: excluded.  In such case, this License incorporates the limitation as if
                    390: written in the body of this License.
                    391: 
                    392:   13. The Free Software Foundation may publish revised and/or new
                    393: versions of the Library General Public License from time to time.
                    394: Such new versions will be similar in spirit to the present version,
                    395: but may differ in detail to address new problems or concerns.
                    396: 
                    397: Each version is given a distinguishing version number.  If the Library
                    398: specifies a version number of this License which applies to it and
                    399: "any later version", you have the option of following the terms and
                    400: conditions either of that version or of any later version published by
                    401: the Free Software Foundation.  If the Library does not specify a
                    402: license version number, you may choose any version ever published by
                    403: the Free Software Foundation.
                    404: 
                    405:   14. If you wish to incorporate parts of the Library into other free
                    406: programs whose distribution conditions are incompatible with these,
                    407: write to the author to ask for permission.  For software which is
                    408: copyrighted by the Free Software Foundation, write to the Free
                    409: Software Foundation; we sometimes make exceptions for this.  Our
                    410: decision will be guided by the two goals of preserving the free status
                    411: of all derivatives of our free software and of promoting the sharing
                    412: and reuse of software generally.
                    413: 
                    414:                            NO WARRANTY
                    415: 
                    416:   15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
                    417: WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
                    418: EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
                    419: OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
                    420: KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
                    421: IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
                    422: PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
                    423: LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
                    424: THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
                    425: 
                    426:   16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
                    427: WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
