It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + . + Preamble + . + The licenses for most software are designed to take away your + freedom to share and change it. By contrast, the GNU General Public + Licenses are intended to guarantee your freedom to share and change + free software--to make sure the software is free for all its users. + . + This license, the Lesser General Public License, applies to some + specially designated software packages--typically libraries--of the + Free Software Foundation and other authors who decide to use it. You + can use it too, but we suggest you first think carefully about whether + this license or the ordinary General Public License is the better + strategy to use in any particular case, based on the explanations below. + . + When we speak of free software, we are referring to freedom of use, + not price. Our General Public Licenses are designed to make sure that + you have the freedom to distribute copies of free software (and charge + for this service if you wish); that you receive source code or can get + it if you want it; that you can change the software and use pieces of + it in new free programs; and that you are informed that you can do + these things. + . + To protect your rights, we need to make restrictions that forbid + distributors to deny you these rights or to ask you to surrender these + rights. These restrictions translate to certain responsibilities for + you if you distribute copies of the library or if you modify it. + . + For example, if you distribute copies of the library, whether gratis + or for a fee, you must give the recipients all the rights that we gave + you. You must make sure that they, too, receive or can get the source + code. If you link other code with the library, you must provide + complete object files to the recipients, so that they can relink them + with the library after making changes to the library and recompiling + it. And you must show them these terms so they know their rights. + . + We protect your rights with a two-step method: (1) we copyright the + library, and (2) we offer you this license, which gives you legal + permission to copy, distribute and/or modify the library. + . + To protect each distributor, we want to make it very clear that + there is no warranty for the free library. Also, if the library is + modified by someone else and passed on, the recipients should know + that what they have is not the original version, so that the original + author's reputation will not be affected by problems that might be + introduced by others. + . + Finally, software patents pose a constant threat to the existence of + any free program. We wish to make sure that a company cannot + effectively restrict the users of a free program by obtaining a + restrictive license from a patent holder. Therefore, we insist that + any patent license obtained for a version of the library must be + consistent with the full freedom of use specified in this license. + . + Most GNU software, including some libraries, is covered by the + ordinary GNU General Public License. This license, the GNU Lesser + General Public License, applies to certain designated libraries, and + is quite different from the ordinary General Public License. We use + this license for certain libraries in order to permit linking those + libraries into non-free programs. + . + When a program is linked with a library, whether statically or using + a shared library, the combination of the two is legally speaking a + combined work, a derivative of the original library. The ordinary + General Public License therefore permits such linking only if the + entire combination fits its criteria of freedom. The Lesser General + Public License permits more lax criteria for linking other code with + the library. + . + We call this license the "Lesser" General Public License because it + does Less to protect the user's freedom than the ordinary General + Public License. It also provides other free software developers Less + of an advantage over competing non-free programs. These disadvantages + are the reason we use the ordinary General Public License for many + libraries. However, the Lesser license provides advantages in certain + special circumstances. + . + For example, on rare occasions, there may be a special need to + encourage the widest possible use of a certain library, so that it becomes + a de-facto standard. To achieve this, non-free programs must be + allowed to use the library. A more frequent case is that a free + library does the same job as widely used non-free libraries. In this + case, there is little to gain by limiting the free library to free + software only, so we use the Lesser General Public License. + . + In other cases, permission to use a particular library in non-free + programs enables a greater number of people to use a large body of + free software. For example, permission to use the GNU C Library in + non-free programs enables many more people to use the whole GNU + operating system, as well as its variant, the GNU/Linux operating + system. + . + Although the Lesser General Public License is Less protective of the + users' freedom, it does ensure that the user of a program that is + linked with the Library has the freedom and the wherewithal to run + that program using a modified version of the Library. + . + The precise terms and conditions for copying, distribution and + modification follow. Pay close attention to the difference between a + "work based on the library" and a "work that uses the library". The + former contains code derived from the library, whereas the latter must + be combined with the library in order to run. + . + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + . + 0. This License Agreement applies to any software library or other + program which contains a notice placed by the copyright holder or + other authorized party saying it may be distributed under the terms of + this Lesser General Public License (also called "this License"). + Each licensee is addressed as "you". + . + A "library" means a collection of software functions and/or data + prepared so as to be conveniently linked with application programs + (which use some of those functions and data) to form executables. + . + The "Library", below, refers to any such software library or work + which has been distributed under these terms. A "work based on the + Library" means either the Library or any derivative work under + copyright law: that is to say, a work containing the Library or a + portion of it, either verbatim or with modifications and/or translated + straightforwardly into another language. (Hereinafter, translation is + included without limitation in the term "modification".) + . + "Source code" for a work means the preferred form of the work for + making modifications to it. For a library, complete source code means + all the source code for all modules it contains, plus any associated + interface definition files, plus the scripts used to control compilation + and installation of the library. + . + Activities other than copying, distribution and modification are not + covered by this License; they are outside its scope. The act of + running a program using the Library is not restricted, and output from + such a program is covered only if its contents constitute a work based + on the Library (independent of the use of the Library in a tool for + writing it). Whether that is true depends on what the Library does + and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's + complete source code as you receive it, in any medium, provided that + you conspicuously and appropriately publish on each copy an + appropriate copyright notice and disclaimer of warranty; keep intact + all the notices that refer to this License and to the absence of any + warranty; and distribute a copy of this License along with the + Library. + . + You may charge a fee for the physical act of transferring a copy, + and you may at your option offer warranty protection in exchange for a + fee. + . + 2. You may modify your copy or copies of the Library or any portion + of it, thus forming a work based on the Library, and copy and + distribute such modifications or work under the terms of Section 1 + above, provided that you also meet all of these conditions: + . + a) The modified work must itself be a software library. + . + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + . + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + . + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + . + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + . + These requirements apply to the modified work as a whole. If + identifiable sections of that work are not derived from the Library, + and can be reasonably considered independent and separate works in + themselves, then this License, and its terms, do not apply to those + sections when you distribute them as separate works. But when you + distribute the same sections as part of a whole which is a work based + on the Library, the distribution of the whole must be on the terms of + this License, whose permissions for other licensees extend to the + entire whole, and thus to each and every part regardless of who wrote + it. + . + Thus, it is not the intent of this section to claim rights or contest + your rights to work written entirely by you; rather, the intent is to + exercise the right to control the distribution of derivative or + collective works based on the Library. + . + In addition, mere aggregation of another work not based on the Library + with the Library (or with a work based on the Library) on a volume of + a storage or distribution medium does not bring the other work under + the scope of this License. + . + 3. You may opt to apply the terms of the ordinary GNU General Public + License instead of this License to a given copy of the Library. To do + this, you must alter all the notices that refer to this License, so + that they refer to the ordinary GNU General Public License, version 2, + instead of to this License. (If a newer version than version 2 of the + ordinary GNU General Public License has appeared, then you can specify + that version instead if you wish.) Do not make any other change in + these notices. + . + Once this change is made in a given copy, it is irreversible for + that copy, so the ordinary GNU General Public License applies to all + subsequent copies and derivative works made from that copy. + . + This option is useful when you wish to copy part of the code of + the Library into a program that is not a library. + . + 4. You may copy and distribute the Library (or a portion or + derivative of it, under Section 2) in object code or executable form + under the terms of Sections 1 and 2 above provided that you accompany + it with the complete corresponding machine-readable source code, which + must be distributed under the terms of Sections 1 and 2 above on a + medium customarily used for software interchange. + . + If distribution of object code is made by offering access to copy + from a designated place, then offering equivalent access to copy the + source code from the same place satisfies the requirement to + distribute the source code, even though third parties are not + compelled to copy the source along with the object code. + . + 5. A program that contains no derivative of any portion of the + Library, but is designed to work with the Library by being compiled or + linked with it, is called a "work that uses the Library". Such a + work, in isolation, is not a derivative work of the Library, and + therefore falls outside the scope of this License. + . + However, linking a "work that uses the Library" with the Library + creates an executable that is a derivative of the Library (because it + contains portions of the Library), rather than a "work that uses the + library". The executable is therefore covered by this License. + Section 6 states terms for distribution of such executables. + . + When a "work that uses the Library" uses material from a header file + that is part of the Library, the object code for the work may be a + derivative work of the Library even though the source code is not. + Whether this is true is especially significant if the work can be + linked without the Library, or if the work is itself a library. The + threshold for this to be true is not precisely defined by law. + . + If such an object file uses only numerical parameters, data + structure layouts and accessors, and small macros and small inline + functions (ten lines or less in length), then the use of the object + file is unrestricted, regardless of whether it is legally a derivative + work. (Executables containing this object code plus portions of the + Library will still fall under Section 6.) + . + Otherwise, if the work is a derivative of the Library, you may + distribute the object code for the work under the terms of Section 6. + Any executables containing that work also fall under Section 6, + whether or not they are linked directly with the Library itself. + . + 6. As an exception to the Sections above, you may also combine or + link a "work that uses the Library" with the Library to produce a + work containing portions of the Library, and distribute that work + under terms of your choice, provided that the terms permit + modification of the work for the customer's own use and reverse + engineering for debugging such modifications. + . + You must give prominent notice with each copy of the work that the + Library is used in it and that the Library and its use are covered by + this License. You must supply a copy of this License. If the work + during execution displays copyright notices, you must include the + copyright notice for the Library among them, as well as a reference + directing the user to the copy of this License. Also, you must do one + of these things: + . + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + . + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + . + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + . + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + . + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + . + For an executable, the required form of the "work that uses the + Library" must include any data and utility programs needed for + reproducing the executable from it. However, as a special exception, + the materials to be distributed need not include anything that is + normally distributed (in either source or binary form) with the major + components (compiler, kernel, and so on) of the operating system on + which the executable runs, unless that component itself accompanies + the executable. + . + It may happen that this requirement contradicts the license + restrictions of other proprietary libraries that do not normally + accompany the operating system. Such a contradiction means you cannot + use both them and the Library together in an executable that you + distribute. + . + 7. You may place library facilities that are a work based on the + Library side-by-side in a single library together with other library + facilities not covered by this License, and distribute such a combined + library, provided that the separate distribution of the work based on + the Library and of the other library facilities is otherwise + permitted, and provided that you do these two things: + . + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + . + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + . + 8. You may not copy, modify, sublicense, link with, or distribute + the Library except as expressly provided under this License. Any + attempt otherwise to copy, modify, sublicense, link with, or + distribute the Library is void, and will automatically terminate your + rights under this License. However, parties who have received copies, + or rights, from you under this License will not have their licenses + terminated so long as such parties remain in full compliance. + . + 9. You are not required to accept this License, since you have not + signed it. However, nothing else grants you permission to modify or + distribute the Library or its derivative works. These actions are + prohibited by law if you do not accept this License. Therefore, by + modifying or distributing the Library (or any work based on the + Library), you indicate your acceptance of this License to do so, and + all its terms and conditions for copying, distributing or modifying + the Library or works based on it. + . + 10. Each time you redistribute the Library (or any work based on the + Library), the recipient automatically receives a license from the + original licensor to copy, distribute, link with or modify the Library + subject to these terms and conditions. You may not impose any further + restrictions on the recipients' exercise of the rights granted herein. + You are not responsible for enforcing compliance by third parties with + this License. + . + 11. If, as a consequence of a court judgment or allegation of patent + infringement or for any other reason (not limited to patent issues), + conditions are imposed on you (whether by court order, agreement or + otherwise) that contradict the conditions of this License, they do not + excuse you from the conditions of this License. If you cannot + distribute so as to satisfy simultaneously your obligations under this + License and any other pertinent obligations, then as a consequence you + may not distribute the Library at all. For example, if a patent + license would not permit royalty-free redistribution of the Library by + all those who receive copies directly or indirectly through you, then + the only way you could satisfy both it and this License would be to + refrain entirely from distribution of the Library. + . + If any portion of this section is held invalid or unenforceable under any + particular circumstance, the balance of the section is intended to apply, + and the section as a whole is intended to apply in other circumstances. + . + It is not the purpose of this section to induce you to infringe any + patents or other property right claims or to contest validity of any + such claims; this section has the sole purpose of protecting the + integrity of the free software distribution system which is + implemented by public license practices. Many people have made + generous contributions to the wide range of software distributed + through that system in reliance on consistent application of that + system; it is up to the author/donor to decide if he or she is willing + to distribute software through any other system and a licensee cannot + impose that choice. + . + This section is intended to make thoroughly clear what is believed to + be a consequence of the rest of this License. + . + 12. If the distribution and/or use of the Library is restricted in + certain countries either by patents or by copyrighted interfaces, the + original copyright holder who places the Library under this License may add + an explicit geographical distribution limitation excluding those countries, + so that distribution is permitted only in or among countries not thus + excluded. In such case, this License incorporates the limitation as if + written in the body of this License. + . + 13. The Free Software Foundation may publish revised and/or new + versions of the Lesser General Public License from time to time. + Such new versions will be similar in spirit to the present version, + but may differ in detail to address new problems or concerns. + . + Each version is given a distinguishing version number. If the Library + specifies a version number of this License which applies to it and + "any later version", you have the option of following the terms and + conditions either of that version or of any later version published by + the Free Software Foundation. If the Library does not specify a + license version number, you may choose any version ever published by + the Free Software Foundation. + . + 14. If you wish to incorporate parts of the Library into other free + programs whose distribution conditions are incompatible with these, + write to the author to ask for permission. For software which is + copyrighted by the Free Software Foundation, write to the Free + Software Foundation; we sometimes make exceptions for this. Our + decision will be guided by the two goals of preserving the free status + of all derivatives of our free software and of promoting the sharing + and reuse of software generally. + . + NO WARRANTY + . + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO + WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. + EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR + OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY + KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE + IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR + PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE + LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME + THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + . + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN + WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY + AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU + FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR + CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE + LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING + RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A + FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF + SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH + DAMAGES. + . + END OF TERMS AND CONDITIONS + . + How to Apply These Terms to Your New Libraries + . + If you develop a new library, and you want it to be of the greatest + possible use to the public, we recommend making it free software that + everyone can redistribute and change. You can do so by permitting + redistribution under these terms (or, alternatively, under the terms of the + ordinary General Public License). + . + To apply these terms, attach the following notices to the library. It is + safest to attach them to the start of each source file to most effectively + convey the exclusion of warranty; and each file should have at least the + "copyright" line and a pointer to where the full notice is found. + . + + Copyright (C) + . + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + . + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
