				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.
 |

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.
 | 
						|

						|

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.
