# GNU LIBRARY GENERAL PUBLIC LICENSE
|
||||
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1991 Free Software Foundation, Inc.
|
||||
51 Franklin St, 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 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.
|
||||
|
||||
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
|
