|

|
||
|
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 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.

||

|

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.
