- Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- [This is the first released version of the Lesser GPL. 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.
-
-### 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:
-
- 1. The modified work must itself be a software library.
-
- 2. You must cause the files modified to carry prominent notices
- stating that you changed the files and the date of any change.
-
- 3. You must cause the whole of the work to be licensed at no
- charge to all third parties under the terms of this License.
-
- 4. 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:
-
- 1. 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.)
-
- 2. 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.
-
- 3. 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.
-
- 4. 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.
-
- 5. 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:
-
- 1. 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.
-
- 2. 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. Here is a sample; alter the names:
