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. - . - <one line to give the library's name and a brief idea of what it does.> - Copyright (C) <year> <name of author> - . - 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. See the GNU - Lesser General Public License for more details. - . - You should have received a copy of the GNU Lesser General Public - License along with this library; if not, write to the Free Software - Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA - . - Also add information on how to contact you by electronic and paper mail. - . - You should also get your employer (if you work as a programmer) or your - school, if any, to sign a "copyright disclaimer" for the library, if - necessary.

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. - - <one line to give the library's name and a brief idea of what it does.> - Copyright (C) <year> <name of author> - - 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.
