It is + numbered 2 because it goes with version 2 of the ordinary GPL.] + +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 Library General Public License, applies to some +specially designated Free Software Foundation software, and to any +other libraries whose authors decide to use it. You can use it for +your libraries, too. + + When we speak of free software, we are referring to freedom, 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 or use pieces of it in +new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the 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 a program 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. + + Our method of protecting your rights has two steps: (1) copyright +the library, and (2) offer you this license which gives you legal +permission to copy, distribute and/or modify the library. + + Also, for each distributor's protection, we want to make certain +that everyone understands that there is no warranty for this free +library. If the library is modified by someone else and passed on, we +want its recipients to know that what they have is not the original +version, so that any problems introduced by others will not reflect on +the original authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that companies distributing free +software will individually obtain patent licenses, thus in effect +transforming the program into proprietary software. To prevent this, +we have made it clear that any patent must be licensed for everyone's +free use or not licensed at all. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License, which was designed for utility +programs. This license, the GNU Library General Public License, +applies to certain designated libraries. This license is quite +different from the ordinary one; be sure to read it in full, and don't +assume that anything in it is the same as in the ordinary license. + + The reason we have a separate public license for some libraries is +that they blur the distinction we usually make between modifying or +adding to a program and simply using it. Linking a program with a +library, without changing the library, is in some sense simply using +the library, and is analogous to running a utility program or +application program. However, in a textual and legal sense, the linked +executable is a combined work, a derivative of the original library, +and the ordinary General Public License treats it as such. + + Because of this blurred distinction, using the ordinary General +Public License for libraries did not effectively promote software +sharing, because most developers did not use the libraries. We +concluded that weaker conditions might promote sharing better. + + However, unrestricted linking of non-free programs would deprive the +users of those programs of all benefit from the free status of the +libraries themselves. This Library General Public License is intended +to permit developers of non-free programs to use free libraries, while +preserving your freedom as a user of such programs to change the free +libraries that are incorporated in them. (We have not seen how to +achieve this as regards changes in header files, but we have achieved +it as regards changes in the actual functions of the Library.) The +hope is that this will lead to faster development of free libraries. + + 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, while the latter only +works together with the library. + + Note that it is possible for a library to be covered by the ordinary +General Public License rather than by this special one. + + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library which + contains a notice placed by the copyright holder or other + authorized party saying it may be distributed under the terms of + this Library 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 compile 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. 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. + + c. 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. + + d. 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 source code 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 to 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 Library 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 AN 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 Library General Public License as published + by the Free Software Foundation; either version 2 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 + Library General Public License for more details. + + You should have received a copy of the GNU General Public License along + with this program; if not, write to the Free Software Foundation, Inc., + 59 Temple Place, Suite 330, Boston, MA 02111-1307, 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. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the library + `Frob' (a library for tweaking knobs) written by James Random Hacker. + + SIGNATURE OF TY COON, 1 April 1990 + Ty Coon, President of Vice + + That's all there is to it! + |
