-nearly freezed(i.e. during beta, a while after the release until

- GNU LIBRARY GENERAL PUBLIC LICENSE
-
- Version 2, June 1991
-
-
-
- Copyright (C) 1991 Free Software Foundation, Inc.
-
- 675 Mass Ave, Cambridge, MA 02139, 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 library GPL. 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.
-
-\f
-
- 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.
-
-\f
-
- GNU LIBRARY GENERAL PUBLIC LICENSE
-
- 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.
-
-\f
-
- 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.
-
-\f
-
- 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.
-
-\f
-
- 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.
-
-\f
-
- 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.
-
-\f
-
- 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.
-
-\f
-
- 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
-
-\f
-
- Appendix: How to Apply These Terms to Your New Libraries
-
-
-
- If you develop a new library, and you want it to be of the greatest
-
-possible use to the public, we recommend making it free software that
-
-everyone can redistribute and change. You can do so by permitting
-
-redistribution under these terms (or, alternatively, under the terms of the
-
-ordinary General Public License).
-
-
-
- To apply these terms, attach the following notices to the library. It is
-
-safest to attach them to the start of each source file to most effectively
-
-convey the exclusion of warranty; and each file should have at least the
-
-"copyright" line and a pointer to where the full notice is found.
-
-
-
-
-
- Copyright (C)
-
-
-
- This library is free software; you can redistribute it and/or
-
- modify it under the terms of the GNU 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 Library General Public
-
- License along with this library; if not, write to the Free
-
- Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, 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.
-
