0006  Everyone is permitted to copy and distribute verbatim copies
0007  of this license document, but changing it is not allowed.
0008 
0009 [This is the first released version of the Lesser GPL.  It also counts
0010  as the successor of the GNU Library Public License, version 2, hence
0011  the version number 2.1.]
0012 
0013                             Preamble
0014 
0015   The licenses for most software are designed to take away your
0016 freedom to share and change it.  By contrast, the GNU General Public
0017 Licenses are intended to guarantee your freedom to share and change
0018 free software--to make sure the software is free for all its users.
0019 
0020   This license, the Lesser General Public License, applies to some
0021 specially designated software packages--typically libraries--of the
0022 Free Software Foundation and other authors who decide to use it.  You
0023 can use it too, but we suggest you first think carefully about whether
0024 this license or the ordinary General Public License is the better
0025 strategy to use in any particular case, based on the explanations below.
0026 
0027   When we speak of free software, we are referring to freedom of use,
0028 not price.  Our General Public Licenses are designed to make sure that
0029 you have the freedom to distribute copies of free software (and charge
0030 for this service if you wish); that you receive source code or can get
0031 it if you want it; that you can change the software and use pieces of
0032 it in new free programs; and that you are informed that you can do
0033 these things.
0034 
0035   To protect your rights, we need to make restrictions that forbid
0036 distributors to deny you these rights or to ask you to surrender these
0037 rights.  These restrictions translate to certain responsibilities for
0038 you if you distribute copies of the library or if you modify it.
0039 
0040   For example, if you distribute copies of the library, whether gratis
0041 or for a fee, you must give the recipients all the rights that we gave
0042 you.  You must make sure that they, too, receive or can get the source
0043 code.  If you link other code with the library, you must provide
0044 complete object files to the recipients, so that they can relink them
0045 with the library after making changes to the library and recompiling
0046 it.  And you must show them these terms so they know their rights.
0047 
0048   We protect your rights with a two-step method: (1) we copyright the
0049 library, and (2) we offer you this license, which gives you legal
0050 permission to copy, distribute and/or modify the library.
0051 
0052   To protect each distributor, we want to make it very clear that
0053 there is no warranty for the free library.  Also, if the library is
0054 modified by someone else and passed on, the recipients should know
0055 that what they have is not the original version, so that the original
0056 author's reputation will not be affected by problems that might be
0057 introduced by others.
0058 
0059   Finally, software patents pose a constant threat to the existence of
0060 any free program.  We wish to make sure that a company cannot
0061 effectively restrict the users of a free program by obtaining a
0062 restrictive license from a patent holder.  Therefore, we insist that
0063 any patent license obtained for a version of the library must be
0064 consistent with the full freedom of use specified in this license.
0065 
0066   Most GNU software, including some libraries, is covered by the
0067 ordinary GNU General Public License.  This license, the GNU Lesser
0068 General Public License, applies to certain designated libraries, and
0069 is quite different from the ordinary General Public License.  We use
0070 this license for certain libraries in order to permit linking those
0071 libraries into non-free programs.
0072 
0073   When a program is linked with a library, whether statically or using
0074 a shared library, the combination of the two is legally speaking a
0075 combined work, a derivative of the original library.  The ordinary
0076 General Public License therefore permits such linking only if the
0077 entire combination fits its criteria of freedom.  The Lesser General
0078 Public License permits more lax criteria for linking other code with
0079 the library.
0080 
0081   We call this license the "Lesser" General Public License because it
0082 does Less to protect the user's freedom than the ordinary General
0083 Public License.  It also provides other free software developers Less
0084 of an advantage over competing non-free programs.  These disadvantages
0085 are the reason we use the ordinary General Public License for many
0086 libraries.  However, the Lesser license provides advantages in certain
0087 special circumstances.
0088 
0089   For example, on rare occasions, there may be a special need to
0090 encourage the widest possible use of a certain library, so that it becomes
0091 a de-facto standard.  To achieve this, non-free programs must be
0092 allowed to use the library.  A more frequent case is that a free
0093 library does the same job as widely used non-free libraries.  In this
0094 case, there is little to gain by limiting the free library to free
0095 software only, so we use the Lesser General Public License.
0096 
0097   In other cases, permission to use a particular library in non-free
0098 programs enables a greater number of people to use a large body of
0099 free software.  For example, permission to use the GNU C Library in
0100 non-free programs enables many more people to use the whole GNU
0101 operating system, as well as its variant, the GNU/Linux operating
0102 system.
0103 
0104   Although the Lesser General Public License is Less protective of the
0105 users' freedom, it does ensure that the user of a program that is
0106 linked with the Library has the freedom and the wherewithal to run
0107 that program using a modified version of the Library.
0108 
0109   The precise terms and conditions for copying, distribution and
0110 modification follow.  Pay close attention to the difference between a
0111 "work based on the library" and a "work that uses the library".  The
0112 former contains code derived from the library, whereas the latter must
0113 be combined with the library in order to run.
0114 
0115                   GNU LESSER GENERAL PUBLIC LICENSE
0116    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0117 
0118   0. This License Agreement applies to any software library or other
0119 program which contains a notice placed by the copyright holder or
0120 other authorized party saying it may be distributed under the terms of
0121 this Lesser General Public License (also called "this License").
0122 Each licensee is addressed as "you".
0123 
0124   A "library" means a collection of software functions and/or data
0125 prepared so as to be conveniently linked with application programs
0126 (which use some of those functions and data) to form executables.
0127 
0128   The "Library", below, refers to any such software library or work
0129 which has been distributed under these terms.  A "work based on the
0130 Library" means either the Library or any derivative work under
0131 copyright law: that is to say, a work containing the Library or a
0132 portion of it, either verbatim or with modifications and/or translated
0133 straightforwardly into another language.  (Hereinafter, translation is
0134 included without limitation in the term "modification".)
0135 
0136   "Source code" for a work means the preferred form of the work for
0137 making modifications to it.  For a library, complete source code means
0138 all the source code for all modules it contains, plus any associated
0139 interface definition files, plus the scripts used to control compilation
0140 and installation of the library.
0141 
0142   Activities other than copying, distribution and modification are not
0143 covered by this License; they are outside its scope.  The act of
0144 running a program using the Library is not restricted, and output from
0145 such a program is covered only if its contents constitute a work based
0146 on the Library (independent of the use of the Library in a tool for
0147 writing it).  Whether that is true depends on what the Library does
0148 and what the program that uses the Library does.
0149   
0150   1. You may copy and distribute verbatim copies of the Library's
0151 complete source code as you receive it, in any medium, provided that
0152 you conspicuously and appropriately publish on each copy an
0153 appropriate copyright notice and disclaimer of warranty; keep intact
0154 all the notices that refer to this License and to the absence of any
0155 warranty; and distribute a copy of this License along with the
0156 Library.
0157 
0158   You may charge a fee for the physical act of transferring a copy,
0159 and you may at your option offer warranty protection in exchange for a
0160 fee.
0161 
0162   2. You may modify your copy or copies of the Library or any portion
0163 of it, thus forming a work based on the Library, and copy and
0164 distribute such modifications or work under the terms of Section 1
0165 above, provided that you also meet all of these conditions:
0166 
0167     a) The modified work must itself be a software library.
0168 
0169     b) You must cause the files modified to carry prominent notices
0170     stating that you changed the files and the date of any change.
0171 
0172     c) You must cause the whole of the work to be licensed at no
0173     charge to all third parties under the terms of this License.
0174 
0175     d) If a facility in the modified Library refers to a function or a
0176     table of data to be supplied by an application program that uses
0177     the facility, other than as an argument passed when the facility
0178     is invoked, then you must make a good faith effort to ensure that,
0179     in the event an application does not supply such function or
0180     table, the facility still operates, and performs whatever part of
0181     its purpose remains meaningful.
0182 
0183     (For example, a function in a library to compute square roots has
0184     a purpose that is entirely well-defined independent of the
0185     application.  Therefore, Subsection 2d requires that any
0186     application-supplied function or table used by this function must
0187     be optional: if the application does not supply it, the square
0188     root function must still compute square roots.)
0189 
0190 These requirements apply to the modified work as a whole.  If
0191 identifiable sections of that work are not derived from the Library,
0192 and can be reasonably considered independent and separate works in
0193 themselves, then this License, and its terms, do not apply to those
0194 sections when you distribute them as separate works.  But when you
0195 distribute the same sections as part of a whole which is a work based
0196 on the Library, the distribution of the whole must be on the terms of
0197 this License, whose permissions for other licensees extend to the
0198 entire whole, and thus to each and every part regardless of who wrote
0199 it.
0200 
0201 Thus, it is not the intent of this section to claim rights or contest
0202 your rights to work written entirely by you; rather, the intent is to
0203 exercise the right to control the distribution of derivative or
0204 collective works based on the Library.
0205 
0206 In addition, mere aggregation of another work not based on the Library
0207 with the Library (or with a work based on the Library) on a volume of
0208 a storage or distribution medium does not bring the other work under
0209 the scope of this License.
0210 
0211   3. You may opt to apply the terms of the ordinary GNU General Public
0212 License instead of this License to a given copy of the Library.  To do
0213 this, you must alter all the notices that refer to this License, so
0214 that they refer to the ordinary GNU General Public License, version 2,
0215 instead of to this License.  (If a newer version than version 2 of the
0216 ordinary GNU General Public License has appeared, then you can specify
0217 that version instead if you wish.)  Do not make any other change in
0218 these notices.
0219 
0220   Once this change is made in a given copy, it is irreversible for
0221 that copy, so the ordinary GNU General Public License applies to all
0222 subsequent copies and derivative works made from that copy.
0223 
0224   This option is useful when you wish to copy part of the code of
0225 the Library into a program that is not a library.
0226 
0227   4. You may copy and distribute the Library (or a portion or
0228 derivative of it, under Section 2) in object code or executable form
0229 under the terms of Sections 1 and 2 above provided that you accompany
0230 it with the complete corresponding machine-readable source code, which
0231 must be distributed under the terms of Sections 1 and 2 above on a
0232 medium customarily used for software interchange.
0233 
0234   If distribution of object code is made by offering access to copy
0235 from a designated place, then offering equivalent access to copy the
0236 source code from the same place satisfies the requirement to
0237 distribute the source code, even though third parties are not
0238 compelled to copy the source along with the object code.
0239 
0240   5. A program that contains no derivative of any portion of the
0241 Library, but is designed to work with the Library by being compiled or
0242 linked with it, is called a "work that uses the Library".  Such a
0243 work, in isolation, is not a derivative work of the Library, and
0244 therefore falls outside the scope of this License.
0245 
0246   However, linking a "work that uses the Library" with the Library
0247 creates an executable that is a derivative of the Library (because it
0248 contains portions of the Library), rather than a "work that uses the
0249 library".  The executable is therefore covered by this License.
0250 Section 6 states terms for distribution of such executables.
0251 
0252   When a "work that uses the Library" uses material from a header file
0253 that is part of the Library, the object code for the work may be a
0254 derivative work of the Library even though the source code is not.
0255 Whether this is true is especially significant if the work can be
0256 linked without the Library, or if the work is itself a library.  The
0257 threshold for this to be true is not precisely defined by law.
0258 
0259   If such an object file uses only numerical parameters, data
0260 structure layouts and accessors, and small macros and small inline
0261 functions (ten lines or less in length), then the use of the object
0262 file is unrestricted, regardless of whether it is legally a derivative
0263 work.  (Executables containing this object code plus portions of the
0264 Library will still fall under Section 6.)
0265 
0266   Otherwise, if the work is a derivative of the Library, you may
0267 distribute the object code for the work under the terms of Section 6.
0268 Any executables containing that work also fall under Section 6,
0269 whether or not they are linked directly with the Library itself.
0270 
0271   6. As an exception to the Sections above, you may also combine or
0272 link a "work that uses the Library" with the Library to produce a
0273 work containing portions of the Library, and distribute that work
0274 under terms of your choice, provided that the terms permit
0275 modification of the work for the customer's own use and reverse
0276 engineering for debugging such modifications.
0277 
0278   You must give prominent notice with each copy of the work that the
0279 Library is used in it and that the Library and its use are covered by
0280 this License.  You must supply a copy of this License.  If the work
0281 during execution displays copyright notices, you must include the
0282 copyright notice for the Library among them, as well as a reference
0283 directing the user to the copy of this License.  Also, you must do one
0284 of these things:
0285 
0286     a) Accompany the work with the complete corresponding
0287     machine-readable source code for the Library including whatever
0288     changes were used in the work (which must be distributed under
0289     Sections 1 and 2 above); and, if the work is an executable linked
0290     with the Library, with the complete machine-readable "work that
0291     uses the Library", as object code and/or source code, so that the
0292     user can modify the Library and then relink to produce a modified
0293     executable containing the modified Library.  (It is understood
0294     that the user who changes the contents of definitions files in the
0295     Library will not necessarily be able to recompile the application
0296     to use the modified definitions.)
0297 
0298     b) Use a suitable shared library mechanism for linking with the
0299     Library.  A suitable mechanism is one that (1) uses at run time a
0300     copy of the library already present on the user's computer system,
0301     rather than copying library functions into the executable, and (2)
0302     will operate properly with a modified version of the library, if
0303     the user installs one, as long as the modified version is
0304     interface-compatible with the version that the work was made with.
0305 
0306     c) Accompany the work with a written offer, valid for at
0307     least three years, to give the same user the materials
0308     specified in Subsection 6a, above, for a charge no more
0309     than the cost of performing this distribution.
0310 
0311     d) If distribution of the work is made by offering access to copy
0312     from a designated place, offer equivalent access to copy the above
0313     specified materials from the same place.
0314 
0315     e) Verify that the user has already received a copy of these
0316     materials or that you have already sent this user a copy.
0317 
0318   For an executable, the required form of the "work that uses the
0319 Library" must include any data and utility programs needed for
0320 reproducing the executable from it.  However, as a special exception,
0321 the materials to be distributed need not include anything that is
0322 normally distributed (in either source or binary form) with the major
0323 components (compiler, kernel, and so on) of the operating system on
0324 which the executable runs, unless that component itself accompanies
0325 the executable.
0326 
0327   It may happen that this requirement contradicts the license
0328 restrictions of other proprietary libraries that do not normally
0329 accompany the operating system.  Such a contradiction means you cannot
0330 use both them and the Library together in an executable that you
0331 distribute.
0332 
0333   7. You may place library facilities that are a work based on the
0334 Library side-by-side in a single library together with other library
0335 facilities not covered by this License, and distribute such a combined
0336 library, provided that the separate distribution of the work based on
0337 the Library and of the other library facilities is otherwise
0338 permitted, and provided that you do these two things:
0339 
0340     a) Accompany the combined library with a copy of the same work
0341     based on the Library, uncombined with any other library
0342     facilities.  This must be distributed under the terms of the
0343     Sections above.
0344 
0345     b) Give prominent notice with the combined library of the fact
0346     that part of it is a work based on the Library, and explaining
0347     where to find the accompanying uncombined form of the same work.
0348 
0349   8. You may not copy, modify, sublicense, link with, or distribute
0350 the Library except as expressly provided under this License.  Any
0351 attempt otherwise to copy, modify, sublicense, link with, or
0352 distribute the Library is void, and will automatically terminate your
0353 rights under this License.  However, parties who have received copies,
0354 or rights, from you under this License will not have their licenses
0355 terminated so long as such parties remain in full compliance.
0356 
0357   9. You are not required to accept this License, since you have not
0358 signed it.  However, nothing else grants you permission to modify or
0359 distribute the Library or its derivative works.  These actions are
0360 prohibited by law if you do not accept this License.  Therefore, by
0361 modifying or distributing the Library (or any work based on the
0362 Library), you indicate your acceptance of this License to do so, and
0363 all its terms and conditions for copying, distributing or modifying
0364 the Library or works based on it.
0365 
0366   10. Each time you redistribute the Library (or any work based on the
0367 Library), the recipient automatically receives a license from the
0368 original licensor to copy, distribute, link with or modify the Library
0369 subject to these terms and conditions.  You may not impose any further
0370 restrictions on the recipients' exercise of the rights granted herein.
0371 You are not responsible for enforcing compliance by third parties with
0372 this License.
0373 
0374   11. If, as a consequence of a court judgment or allegation of patent
0375 infringement or for any other reason (not limited to patent issues),
0376 conditions are imposed on you (whether by court order, agreement or
0377 otherwise) that contradict the conditions of this License, they do not
0378 excuse you from the conditions of this License.  If you cannot
0379 distribute so as to satisfy simultaneously your obligations under this
0380 License and any other pertinent obligations, then as a consequence you
0381 may not distribute the Library at all.  For example, if a patent
0382 license would not permit royalty-free redistribution of the Library by
0383 all those who receive copies directly or indirectly through you, then
0384 the only way you could satisfy both it and this License would be to
0385 refrain entirely from distribution of the Library.
0386 
0387 If any portion of this section is held invalid or unenforceable under any
0388 particular circumstance, the balance of the section is intended to apply,
0389 and the section as a whole is intended to apply in other circumstances.
0390 
0391 It is not the purpose of this section to induce you to infringe any
0392 patents or other property right claims or to contest validity of any
0393 such claims; this section has the sole purpose of protecting the
0394 integrity of the free software distribution system which is
0395 implemented by public license practices.  Many people have made
0396 generous contributions to the wide range of software distributed
0397 through that system in reliance on consistent application of that
0398 system; it is up to the author/donor to decide if he or she is willing
0399 to distribute software through any other system and a licensee cannot
0400 impose that choice.
0401 
0402 This section is intended to make thoroughly clear what is believed to
0403 be a consequence of the rest of this License.
0404 
0405   12. If the distribution and/or use of the Library is restricted in
0406 certain countries either by patents or by copyrighted interfaces, the
0407 original copyright holder who places the Library under this License may add
0408 an explicit geographical distribution limitation excluding those countries,
0409 so that distribution is permitted only in or among countries not thus
0410 excluded.  In such case, this License incorporates the limitation as if
0411 written in the body of this License.
0412 
0413   13. The Free Software Foundation may publish revised and/or new
0414 versions of the Lesser General Public License from time to time.
0415 Such new versions will be similar in spirit to the present version,
0416 but may differ in detail to address new problems or concerns.
0417 
0418 Each version is given a distinguishing version number.  If the Library
0419 specifies a version number of this License which applies to it and
0420 "any later version", you have the option of following the terms and
0421 conditions either of that version or of any later version published by
0422 the Free Software Foundation.  If the Library does not specify a
0423 license version number, you may choose any version ever published by
0424 the Free Software Foundation.
0425 
0426   14. If you wish to incorporate parts of the Library into other free
0427 programs whose distribution conditions are incompatible with these,
0428 write to the author to ask for permission.  For software which is
0429 copyrighted by the Free Software Foundation, write to the Free
0430 Software Foundation; we sometimes make exceptions for this.  Our
0431 decision will be guided by the two goals of preserving the free status
0432 of all derivatives of our free software and of promoting the sharing
0433 and reuse of software generally.
0434 
0435                             NO WARRANTY
0436 
0437   15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
0438 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

0460            How to Apply These Terms to Your New Libraries
0461 
0462   If you develop a new library, and you want it to be of the greatest
0463 possible use to the public, we recommend making it free software that
0464 everyone can redistribute and change.  You can do so by permitting
0465 redistribution under these terms (or, alternatively, under the terms of the
0466 ordinary General Public License).
0467 
0468   To apply these terms, attach the following notices to the library.  It is
0469 safest to attach them to the start of each source file to most effectively
0470 convey the exclusion of warranty; and each file should have at least the
0471 "copyright" line and a pointer to where the full notice is found.
0472 
0473     <one line to give the library's name and a brief idea of what it does.>
0474     Copyright (C) <year>  <name of author>
0475 
0476     This library is free software; you can redistribute it and/or
0477     modify it under the terms of the GNU Lesser General Public
0478     License as published by the Free Software Foundation; either
0479     version 2.1 of the License, or (at your option) any later version.
0480 
0481     This library is distributed in the hope that it will be useful,
0482     but WITHOUT ANY WARRANTY; without even the implied warranty of
0483     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
0484     Lesser General Public License for more details.
0485 
0486     You should have received a copy of the GNU Lesser General Public
0487     License along with this library; if not, write to the Free Software
0488     Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
0489 
0490 Also add information on how to contact you by electronic and paper mail.
0491 
0492 You should also get your employer (if you work as a programmer) or your
0493 school, if any, to sign a "copyright disclaimer" for the library, if
0494 necessary.  Here is a sample; alter the names:

0497   library `Frob' (a library for tweaking knobs) written by James Random Hacker.
