! 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
! 428: AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
! 429: FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
! 430: CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
! 431: LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
! 432: RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
! 433: FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
! 434: SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
! 435: DAMAGES.
! 436:
! 437: END OF TERMS AND CONDITIONS
! 438:
! 439: Appendix: How to Apply These Terms to Your New Libraries
! 440:
! 441: If you develop a new library, and you want it to be of the greatest
! 442: possible use to the public, we recommend making it free software that
! 443: everyone can redistribute and change. You can do so by permitting
! 444: redistribution under these terms (or, alternatively, under the terms of the
! 445: ordinary General Public License).
! 446:
! 447: To apply these terms, attach the following notices to the library. It is
! 448: safest to attach them to the start of each source file to most effectively
! 449: convey the exclusion of warranty; and each file should have at least the
! 450: "copyright" line and a pointer to where the full notice is found.
! 451:
! 452: <one line to give the library's name and a brief idea of what it does.>
