! 6: Everyone is permitted to copy and distribute verbatim copies
! 7: of this license document, but changing it is not allowed.

! 9: [This is the first released version of the Lesser GPL. It also counts
! 10: as the successor of the GNU Library Public License, version 2, hence
! 11: the version number 2.1.]
! 12:
! 13: Preamble
! 14:
! 15: The licenses for most software are designed to take away your
! 16: freedom to share and change it. By contrast, the GNU General Public
! 17: Licenses are intended to guarantee your freedom to share and change
! 18: free software--to make sure the software is free for all its users.
! 19:
! 20: This license, the Lesser General Public License, applies to some
! 21: specially designated software packages--typically libraries--of the
! 22: Free Software Foundation and other authors who decide to use it. You
! 23: can use it too, but we suggest you first think carefully about whether
! 24: this license or the ordinary General Public License is the better
! 25: strategy to use in any particular case, based on the explanations below.
! 26:
! 27: When we speak of free software, we are referring to freedom of use,
! 28: not price. Our General Public Licenses are designed to make sure that
! 29: you have the freedom to distribute copies of free software (and charge
! 30: for this service if you wish); that you receive source code or can get
! 31: it if you want it; that you can change the software and use pieces of
! 32: it in new free programs; and that you are informed that you can do
! 33: these things.
! 34:
! 35: To protect your rights, we need to make restrictions that forbid
! 36: distributors to deny you these rights or to ask you to surrender these
! 37: rights. These restrictions translate to certain responsibilities for
! 38: you if you distribute copies of the library or if you modify it.
! 39:
! 40: For example, if you distribute copies of the library, whether gratis
! 41: or for a fee, you must give the recipients all the rights that we gave
! 42: you. You must make sure that they, too, receive or can get the source
! 43: code. If you link other code with the library, you must provide
! 44: complete object files to the recipients, so that they can relink them
! 45: with the library after making changes to the library and recompiling
! 46: it. And you must show them these terms so they know their rights.
! 47:
! 48: We protect your rights with a two-step method: (1) we copyright the
! 49: library, and (2) we offer you this license, which gives you legal
! 50: permission to copy, distribute and/or modify the library.
! 51:
! 52: To protect each distributor, we want to make it very clear that
! 53: there is no warranty for the free library. Also, if the library is
! 54: modified by someone else and passed on, the recipients should know
! 55: that what they have is not the original version, so that the original
! 56: author's reputation will not be affected by problems that might be
! 57: introduced by others.
! 58:
! 59: Finally, software patents pose a constant threat to the existence of
! 60: any free program. We wish to make sure that a company cannot
! 61: effectively restrict the users of a free program by obtaining a
! 62: restrictive license from a patent holder. Therefore, we insist that
! 63: any patent license obtained for a version of the library must be
! 64: consistent with the full freedom of use specified in this license.
! 65:
! 66: Most GNU software, including some libraries, is covered by the
! 67: ordinary GNU General Public License. This license, the GNU Lesser
! 68: General Public License, applies to certain designated libraries, and
! 69: is quite different from the ordinary General Public License. We use
! 70: this license for certain libraries in order to permit linking those
! 71: libraries into non-free programs.
! 72:
! 73: When a program is linked with a library, whether statically or using
! 74: a shared library, the combination of the two is legally speaking a
! 75: combined work, a derivative of the original library. The ordinary
! 76: General Public License therefore permits such linking only if the
! 77: entire combination fits its criteria of freedom. The Lesser General
! 78: Public License permits more lax criteria for linking other code with
! 79: the library.
! 80:
! 81: We call this license the "Lesser" General Public License because it
! 82: does Less to protect the user's freedom than the ordinary General
! 83: Public License. It also provides other free software developers Less
! 84: of an advantage over competing non-free programs. These disadvantages
! 85: are the reason we use the ordinary General Public License for many
! 86: libraries. However, the Lesser license provides advantages in certain
! 87: special circumstances.
! 88:
! 89: For example, on rare occasions, there may be a special need to
! 90: encourage the widest possible use of a certain library, so that it becomes
! 91: a de-facto standard. To achieve this, non-free programs must be
! 92: allowed to use the library. A more frequent case is that a free
! 93: library does the same job as widely used non-free libraries. In this
! 94: case, there is little to gain by limiting the free library to free
! 95: software only, so we use the Lesser General Public License.
! 96:
! 97: In other cases, permission to use a particular library in non-free
! 98: programs enables a greater number of people to use a large body of
! 99: free software. For example, permission to use the GNU C Library in
! 100: non-free programs enables many more people to use the whole GNU
! 101: operating system, as well as its variant, the GNU/Linux operating
! 102: system.
! 103:
! 104: Although the Lesser General Public License is Less protective of the
! 105: users' freedom, it does ensure that the user of a program that is
! 106: linked with the Library has the freedom and the wherewithal to run
! 107: that program using a modified version of the Library.
! 108:
! 109: The precise terms and conditions for copying, distribution and
! 110: modification follow. Pay close attention to the difference between a
! 111: "work based on the library" and a "work that uses the library". The
! 112: former contains code derived from the library, whereas the latter must
! 113: be combined with the library in order to run.
! 114:
! 115: GNU LESSER GENERAL PUBLIC LICENSE
! 116: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
! 117:
! 118: 0. This License Agreement applies to any software library or other
! 119: program which contains a notice placed by the copyright holder or
! 120: other authorized party saying it may be distributed under the terms of
! 121: this Lesser General Public License (also called "this License").
! 122: Each licensee is addressed as "you".
! 123:
! 124: A "library" means a collection of software functions and/or data
! 125: prepared so as to be conveniently linked with application programs
! 126: (which use some of those functions and data) to form executables.
! 127:
! 128: The "Library", below, refers to any such software library or work
! 129: which has been distributed under these terms. A "work based on the
! 130: Library" means either the Library or any derivative work under
! 131: copyright law: that is to say, a work containing the Library or a
! 132: portion of it, either verbatim or with modifications and/or translated
! 133: straightforwardly into another language. (Hereinafter, translation is
! 134: included without limitation in the term "modification".)
! 135:
! 136: "Source code" for a work means the preferred form of the work for
! 137: making modifications to it. For a library, complete source code means
! 138: all the source code for all modules it contains, plus any associated
! 139: interface definition files, plus the scripts used to control compilation
! 140: and installation of the library.
! 141:
! 142: Activities other than copying, distribution and modification are not
! 143: covered by this License; they are outside its scope. The act of
! 144: running a program using the Library is not restricted, and output from
! 145: such a program is covered only if its contents constitute a work based
! 146: on the Library (independent of the use of the Library in a tool for
! 147: writing it). Whether that is true depends on what the Library does
! 148: and what the program that uses the Library does.
! 149:
! 150: 1. You may copy and distribute verbatim copies of the Library's
! 151: complete source code as you receive it, in any medium, provided that
! 152: you conspicuously and appropriately publish on each copy an
! 153: appropriate copyright notice and disclaimer of warranty; keep intact
! 154: all the notices that refer to this License and to the absence of any
! 155: warranty; and distribute a copy of this License along with the
! 156: Library.
! 157:
! 158: You may charge a fee for the physical act of transferring a copy,
! 159: and you may at your option offer warranty protection in exchange for a
! 160: fee.
! 161:
! 162: 2. You may modify your copy or copies of the Library or any portion
! 163: of it, thus forming a work based on the Library, and copy and
! 164: distribute such modifications or work under the terms of Section 1
! 165: above, provided that you also meet all of these conditions:
! 166:
! 167: a) The modified work must itself be a software library.
! 168:
! 169: b) You must cause the files modified to carry prominent notices
! 170: stating that you changed the files and the date of any change.
! 171:
! 172: c) You must cause the whole of the work to be licensed at no
! 173: charge to all third parties under the terms of this License.
! 174:
! 175: d) If a facility in the modified Library refers to a function or a
! 176: table of data to be supplied by an application program that uses
! 177: the facility, other than as an argument passed when the facility
! 178: is invoked, then you must make a good faith effort to ensure that,
! 179: in the event an application does not supply such function or
! 180: table, the facility still operates, and performs whatever part of
! 181: its purpose remains meaningful.
! 182:
! 183: (For example, a function in a library to compute square roots has
! 184: a purpose that is entirely well-defined independent of the
! 185: application. Therefore, Subsection 2d requires that any
! 186: application-supplied function or table used by this function must
! 187: be optional: if the application does not supply it, the square
! 188: root function must still compute square roots.)
! 189:
! 190: These requirements apply to the modified work as a whole. If
! 191: identifiable sections of that work are not derived from the Library,
! 192: and can be reasonably considered independent and separate works in
! 193: themselves, then this License, and its terms, do not apply to those
! 194: sections when you distribute them as separate works. But when you
! 195: distribute the same sections as part of a whole which is a work based
! 196: on the Library, the distribution of the whole must be on the terms of
! 197: this License, whose permissions for other licensees extend to the
! 198: entire whole, and thus to each and every part regardless of who wrote
! 199: it.
! 200:
! 201: Thus, it is not the intent of this section to claim rights or contest
! 202: your rights to work written entirely by you; rather, the intent is to
! 203: exercise the right to control the distribution of derivative or
! 204: collective works based on the Library.
! 205:
! 206: In addition, mere aggregation of another work not based on the Library
! 207: with the Library (or with a work based on the Library) on a volume of
! 208: a storage or distribution medium does not bring the other work under
! 209: the scope of this License.
! 210:
! 211: 3. You may opt to apply the terms of the ordinary GNU General Public
! 212: License instead of this License to a given copy of the Library. To do
! 213: this, you must alter all the notices that refer to this License, so
! 214: that they refer to the ordinary GNU General Public License, version 2,
! 215: instead of to this License. (If a newer version than version 2 of the
! 216: ordinary GNU General Public License has appeared, then you can specify
! 217: that version instead if you wish.) Do not make any other change in
! 218: these notices.
! 219:
! 220: Once this change is made in a given copy, it is irreversible for
! 221: that copy, so the ordinary GNU General Public License applies to all
! 222: subsequent copies and derivative works made from that copy.
! 223:
! 224: This option is useful when you wish to copy part of the code of
! 225: the Library into a program that is not a library.
! 226:
! 227: 4. You may copy and distribute the Library (or a portion or
! 228: derivative of it, under Section 2) in object code or executable form
! 229: under the terms of Sections 1 and 2 above provided that you accompany
! 230: it with the complete corresponding machine-readable source code, which
! 231: must be distributed under the terms of Sections 1 and 2 above on a
! 232: medium customarily used for software interchange.
! 233:
! 234: If distribution of object code is made by offering access to copy
! 235: from a designated place, then offering equivalent access to copy the
! 236: source code from the same place satisfies the requirement to
! 237: distribute the source code, even though third parties are not
! 238: compelled to copy the source along with the object code.
! 239:
! 240: 5. A program that contains no derivative of any portion of the
! 241: Library, but is designed to work with the Library by being compiled or
! 242: linked with it, is called a "work that uses the Library". Such a
! 243: work, in isolation, is not a derivative work of the Library, and
! 244: therefore falls outside the scope of this License.
! 245:
! 246: However, linking a "work that uses the Library" with the Library
! 247: creates an executable that is a derivative of the Library (because it
! 248: contains portions of the Library), rather than a "work that uses the
! 249: library". The executable is therefore covered by this License.
! 250: Section 6 states terms for distribution of such executables.
! 251:
! 252: When a "work that uses the Library" uses material from a header file
! 253: that is part of the Library, the object code for the work may be a
! 254: derivative work of the Library even though the source code is not.
! 255: Whether this is true is especially significant if the work can be
! 256: linked without the Library, or if the work is itself a library. The
! 257: threshold for this to be true is not precisely defined by law.
! 258:
! 259: If such an object file uses only numerical parameters, data
! 260: structure layouts and accessors, and small macros and small inline
! 261: functions (ten lines or less in length), then the use of the object
! 262: file is unrestricted, regardless of whether it is legally a derivative
! 263: work. (Executables containing this object code plus portions of the
! 264: Library will still fall under Section 6.)
! 265:
! 266: Otherwise, if the work is a derivative of the Library, you may
! 267: distribute the object code for the work under the terms of Section 6.
! 268: Any executables containing that work also fall under Section 6,
! 269: whether or not they are linked directly with the Library itself.
! 270:
! 271: 6. As an exception to the Sections above, you may also combine or
! 272: link a "work that uses the Library" with the Library to produce a
! 273: work containing portions of the Library, and distribute that work
! 274: under terms of your choice, provided that the terms permit
! 275: modification of the work for the customer's own use and reverse
! 276: engineering for debugging such modifications.
! 277:
! 278: You must give prominent notice with each copy of the work that the
! 279: Library is used in it and that the Library and its use are covered by
! 280: this License. You must supply a copy of this License. If the work
! 281: during execution displays copyright notices, you must include the
! 282: copyright notice for the Library among them, as well as a reference
! 283: directing the user to the copy of this License. Also, you must do one
! 284: of these things:
! 285:
! 286: a) Accompany the work with the complete corresponding
! 287: machine-readable source code for the Library including whatever
! 288: changes were used in the work (which must be distributed under
! 289: Sections 1 and 2 above); and, if the work is an executable linked
! 290: with the Library, with the complete machine-readable "work that
! 291: uses the Library", as object code and/or source code, so that the
! 292: user can modify the Library and then relink to produce a modified
! 293: executable containing the modified Library. (It is understood
! 294: that the user who changes the contents of definitions files in the
! 295: Library will not necessarily be able to recompile the application
! 296: to use the modified definitions.)
! 297:
! 298: b) Use a suitable shared library mechanism for linking with the
! 299: Library. A suitable mechanism is one that (1) uses at run time a
! 300: copy of the library already present on the user's computer system,
! 301: rather than copying library functions into the executable, and (2)
! 302: will operate properly with a modified version of the library, if
! 303: the user installs one, as long as the modified version is
! 304: interface-compatible with the version that the work was made with.
! 305:
! 306: c) Accompany the work with a written offer, valid for at
! 307: least three years, to give the same user the materials
! 308: specified in Subsection 6a, above, for a charge no more
! 309: than the cost of performing this distribution.
! 310:
! 311: d) If distribution of the work is made by offering access to copy
! 312: from a designated place, offer equivalent access to copy the above
! 313: specified materials from the same place.
! 314:
! 315: e) Verify that the user has already received a copy of these
! 316: materials or that you have already sent this user a copy.
! 317:
! 318: For an executable, the required form of the "work that uses the
! 319: Library" must include any data and utility programs needed for
! 320: reproducing the executable from it. However, as a special exception,
! 321: the materials to be distributed need not include anything that is
! 322: normally distributed (in either source or binary form) with the major
! 323: components (compiler, kernel, and so on) of the operating system on
! 324: which the executable runs, unless that component itself accompanies
! 325: the executable.
! 326:
! 327: It may happen that this requirement contradicts the license
! 328: restrictions of other proprietary libraries that do not normally
! 329: accompany the operating system. Such a contradiction means you cannot
! 330: use both them and the Library together in an executable that you
! 331: distribute.
! 332:
! 333: 7. You may place library facilities that are a work based on the
! 334: Library side-by-side in a single library together with other library
! 335: facilities not covered by this License, and distribute such a combined
! 336: library, provided that the separate distribution of the work based on
! 337: the Library and of the other library facilities is otherwise
! 338: permitted, and provided that you do these two things:
! 339:
! 340: a) Accompany the combined library with a copy of the same work
! 341: based on the Library, uncombined with any other library
! 342: facilities. This must be distributed under the terms of the
! 343: Sections above.
! 344:
! 345: b) Give prominent notice with the combined library of the fact
! 346: that part of it is a work based on the Library, and explaining
! 347: where to find the accompanying uncombined form of the same work.
! 348:
! 349: 8. You may not copy, modify, sublicense, link with, or distribute
! 350: the Library except as expressly provided under this License. Any
! 351: attempt otherwise to copy, modify, sublicense, link with, or
! 352: distribute the Library is void, and will automatically terminate your
! 353: rights under this License. However, parties who have received copies,
! 354: or rights, from you under this License will not have their licenses
! 355: terminated so long as such parties remain in full compliance.
! 356:
! 357: 9. You are not required to accept this License, since you have not
! 358: signed it. However, nothing else grants you permission to modify or
! 359: distribute the Library or its derivative works. These actions are
! 360: prohibited by law if you do not accept this License. Therefore, by
! 361: modifying or distributing the Library (or any work based on the
! 362: Library), you indicate your acceptance of this License to do so, and
! 363: all its terms and conditions for copying, distributing or modifying
! 364: the Library or works based on it.
! 365:
! 366: 10. Each time you redistribute the Library (or any work based on the
! 367: Library), the recipient automatically receives a license from the
! 368: original licensor to copy, distribute, link with or modify the Library
! 369: subject to these terms and conditions. You may not impose any further
! 370: restrictions on the recipients' exercise of the rights granted herein.
! 371: You are not responsible for enforcing compliance by third parties with
! 372: this License.
! 373:
! 374: 11. If, as a consequence of a court judgment or allegation of patent
! 375: infringement or for any other reason (not limited to patent issues),
! 376: conditions are imposed on you (whether by court order, agreement or
! 377: otherwise) that contradict the conditions of this License, they do not
! 378: excuse you from the conditions of this License. If you cannot
! 379: distribute so as to satisfy simultaneously your obligations under this
! 380: License and any other pertinent obligations, then as a consequence you
! 381: may not distribute the Library at all. For example, if a patent
! 382: license would not permit royalty-free redistribution of the Library by
! 383: all those who receive copies directly or indirectly through you, then
! 384: the only way you could satisfy both it and this License would be to
! 385: refrain entirely from distribution of the Library.
! 386:
! 387: If any portion of this section is held invalid or unenforceable under any
! 388: particular circumstance, the balance of the section is intended to apply,
! 389: and the section as a whole is intended to apply in other circumstances.
! 390:
! 391: It is not the purpose of this section to induce you to infringe any
! 392: patents or other property right claims or to contest validity of any
! 393: such claims; this section has the sole purpose of protecting the
! 394: integrity of the free software distribution system which is
! 395: implemented by public license practices. Many people have made
! 396: generous contributions to the wide range of software distributed
! 397: through that system in reliance on consistent application of that
! 398: system; it is up to the author/donor to decide if he or she is willing
! 399: to distribute software through any other system and a licensee cannot
! 400: impose that choice.
! 401:
! 402: This section is intended to make thoroughly clear what is believed to
! 403: be a consequence of the rest of this License.
! 404:
! 405: 12. If the distribution and/or use of the Library is restricted in
! 406: certain countries either by patents or by copyrighted interfaces, the
! 407: original copyright holder who places the Library under this License may add
! 408: an explicit geographical distribution limitation excluding those countries,
! 409: so that distribution is permitted only in or among countries not thus
! 410: excluded. In such case, this License incorporates the limitation as if
! 411: written in the body of this License.
! 412:
! 413: 13. The Free Software Foundation may publish revised and/or new
! 414: versions of the Lesser General Public License from time to time.
! 415: Such new versions will be similar in spirit to the present version,
! 416: but may differ in detail to address new problems or concerns.
! 417:
! 418: Each version is given a distinguishing version number. If the Library
! 419: specifies a version number of this License which applies to it and
! 420: "any later version", you have the option of following the terms and
! 421: conditions either of that version or of any later version published by
! 422: the Free Software Foundation. If the Library does not specify a
! 423: license version number, you may choose any version ever published by
! 424: the Free Software Foundation.
! 425:
! 426: 14. If you wish to incorporate parts of the Library into other free
! 427: programs whose distribution conditions are incompatible with these,
! 428: write to the author to ask for permission. For software which is
! 429: copyrighted by the Free Software Foundation, write to the Free
! 430: Software Foundation; we sometimes make exceptions for this. Our
! 431: decision will be guided by the two goals of preserving the free status
! 432: of all derivatives of our free software and of promoting the sharing
! 433: and reuse of software generally.
! 434:
! 435: NO WARRANTY
! 436:
! 437: 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
! 438: WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
! 439: EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
! 440: OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
! 441: KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
! 442: IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
! 443: PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
! 444: LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
! 445: THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
! 446:
! 447: 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
! 448: WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
! 449: AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
! 450: FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
