Everyone is permitted to copy and distribute verbatim copies of this license document,
but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to
share and change it. By contrast, the GNU General Public License is
intended to guarantee your freedom to share and change free software--to make sure
the software is free for all its users. This General Public License
applies to most of the Free Software Foundation's software and to any other
program whose authors commit to using it. (Some other Free Software Foundation
software is covered by the GNU Library General Public License instead.) You
can apply it to your programs, 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
software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or
for a fee, you must give the recipients all the rights that you
have. You must make sure that they, too, receive or can get
the source code. And you must show them these terms so
they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2)
offer you this license which gives you legal permission to copy, distribute and/or
modify the software.
Also, for each author's protection and ours, we want to make certain that
everyone understands that there is no warranty for this free software. If
the software is modified by someone else and passed on, we want its
recipients to know that what they have is not the original, 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 redistributors of a free program will individually obtain
patent licenses, in effect making the program proprietary. To prevent this, we
have made it clear that any patent must be licensed for everyone's free
use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. |
This License applies to any program or other work which
contains a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below, refers
to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law: that is to
say, a work containing the Program or a portion of it, either
verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included
without limitation in the term "modification".) Each licensee is addressed as "you". Activities
other than copying, distribution and modification are not covered by this License; they
are outside its scope. The act of running the Program is not
restricted, and the output from the Program is covered only if its contents
constitute a work based on the Program (independent of having been made by
running the Program). Whether that is true depends on what the Program does. |
1. |
You
may copy and distribute verbatim copies of the Program's 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 give any other recipients of the Program a copy of this License
along with the Program. 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 Program
or any portion of it, thus forming a work based on the Program,
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. |
You must cause
the modified files to carry prominent notices stating that you changed the files
and the date of any change. |
|
b. |
You must cause any work that you distribute or
publish, that in whole or in part contains or is derived from the
Program or any part thereof, to be licensed as a whole at
no charge to all third parties under the terms of this License. |
|
c. |
If the
modified program normally reads commands interactively when run, you must cause it, when
started running for such interactive use in the most ordinary way, to print or
display an announcement including an appropriate copyright notice and a notice that there
is no warranty (or else, saying that you provide a warranty) and that
users may redistribute the program under these conditions, and telling the user how
to view a copy of this License. (Exception: if the Program itself
is interactive but does not normally print such an announcement, your work based on
the Program is not required to print an announcement.) |
|
These requirements apply to the
modified work as a whole. If identifiable sections of that work are
not derived from the Program, 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 Program, 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 Program. In addition, mere aggregation of another work not based on the
Program with the Program (or with a work based on the Program) on
a volume of a storage or distribution medium does not bring the other
work under the scope of this License. |
3. |
You may copy and distribute the Program
(or a work based on it, under Section 2) in object code or
executable form under the terms of Sections 1 and 2 above provided
that you also do one of the following: |
|
a. |
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; or, |
|
b. |
Accompany it with
a written offer, valid for at least three years, to give any third
party, for a charge no more than your cost of physically performing source
distribution, a complete machine-readable copy of the corresponding source code, to be distributed under
the terms of Sections 1 and 2 above on a medium customarily used
for software interchange; or, |
|
c. |
Accompany it with the information you received as to the
offer to distribute corresponding source code. (This alternative is allowed only for
noncommercial distribution and only if you received the program in object code or
executable form with such an offer, in accord with Subsection b above.) |
|
The source
code for a work means the preferred form of the work for making
modifications to it. For an executable work, 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 executable.
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. If distribution of executable or
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
counts as distribution of the source code, even though third parties are not
compelled to copy the source along with the object code. |
4. |
You may not copy,
modify, sublicense, or distribute the Program except as expressly provided under this License.
Any attempt otherwise to copy, modify, sublicense or distribute the Program 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. |
5. |
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 Program or its derivative
works. These actions are prohibited by law if you do not accept
this License. Therefore, by modifying or distributing the Program (or any work
based on the Program), you indicate your acceptance of this License to do
so, and all its terms and conditions for copying, distributing or modifying the
Program or works based on it. |
6. |
Each time you redistribute the Program (or any work
based on the Program), the recipient automatically receives a license from the original
licensor to copy, distribute or modify the Program 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. |
7. |
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 Program at all. For example, if
a patent license would not permit royalty-free redistribution of the Program 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 Program. 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. |
8. |
If the distribution and/or use of the
Program is restricted in certain countries either by patents or by copyrighted interfaces,
the original copyright holder who places the Program 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. |
9. |
The Free
Software Foundation may publish revised and/or new versions of the 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 Program 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 Program does not specify a version number of this License,
you may choose any version ever published by the Free Software Foundation. |
10. |
If you
wish to incorporate parts of the Program into other free programs whose distribution conditions
are different, 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
11. |
BECAUSE
THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE
PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED
IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "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 PROGRAM IS WITH
YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
NECESSARY SERVICING, REPAIR OR CORRECTION. |
12. |
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 PROGRAM 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 PROGRAM (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 PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), 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 Programs
If you develop a new program, and you want it to be
of the greatest possible use to the public, the best way to achieve
this is to make it free software which everyone can redistribute and change under
these terms.
To do so, attach the following notices to the program. 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 program's name and a brief idea of what
it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify it under
the terms of the GNU General Public License as published by the Free
Software Foundation; either version 2 of the License, or (at your option) any
later version.
This program 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 General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc., 59
Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes
passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into proprietary programs.
If your program is a subroutine library, you may consider it more
useful to permit linking proprietary applications with the library. If this is
what you want to do, use the GNU Library General Public License instead
of this License.
GNU Lesser General Public License (LGPL) v2.1
GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies of this license document,
but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also
counts as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your freedom to
share and change it. By contrast, the GNU General Public Licenses are
intended to guarantee your freedom to share and change free software--to make sure
the software is free for all its users.
This license, the Lesser General Public License, applies to some specially designated software
packages--typically libraries--of the Free Software Foundation and other authors who decide to use it.
You can use it too, but we suggest you first think
carefully about whether this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge for
this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use
pieces of it in new free programs; and that you are informed that
you can do these things.
To protect your rights, we need to make restrictions that forbid distributors to
deny you these rights or to ask you to surrender these rights.
These restrictions translate to certain responsibilities for you if you distribute copies of
the library or if you modify it.
For example, if you distribute copies of the library, whether gratis or for
a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get
the source code. If you link other code with the library,
you must provide complete object files to the recipients, so that they can relink
them with the library after making changes to the library and recompiling it.
And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the library,
and (2) we offer you this license, which gives you legal permission to
copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there
is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know that what
they have is not the original version, so that the original author's reputation
will not be affected by problems that might be introduced by others.
Finally, software patents pose a constant threat to the existence of any free
program. We wish to make sure that a company cannot effectively restrict
the users of a free program by obtaining a restrictive license from a
patent holder. Therefore, we insist that any patent license obtained for a
version of the library must be consistent with the full freedom of use
specified in this license.
Most GNU software, including some libraries, is covered by the ordinary GNU General
Public License. This license, the GNU Lesser General Public License, applies to
certain designated libraries, and is quite different from the ordinary General Public License.
We use this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using a
shared library, the combination of the two is legally speaking a combined work,
a derivative of the original library. The ordinary General Public License therefore
permits such linking only if the entire combination fits its criteria of freedom.
The Lesser General Public License permits more lax criteria for linking other code
with the library.
We call this license the "Lesser" General Public License because it does Less
to protect the user's freedom than the ordinary General Public License. It
also provides other free software developers Less of an advantage over competing non-free
programs. These disadvantages are the reason we use the ordinary General Public
License for many libraries. However, the Lesser license provides advantages in certain special
circumstances.
For example, on rare occasions, there may be a special need to encourage
the widest possible use of a certain library, so that it becomes a
de-facto standard. To achieve this, non-free programs must be allowed to use
the library. A more frequent case is that a free library does
the same job as widely used non-free libraries. In this case, there
is little to gain by limiting the free library to free software only,
so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free programs enables
a greater number of people to use a large body of free software.
For example, permission to use the GNU C Library in non-free programs
enables many more people to use the whole GNU operating system, as well
as its variant, the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the users' freedom,
it does ensure that the user of a program that is linked with
the Library has the freedom and the wherewithal to run that program using
a modified version of the Library.
The precise terms and conditions for copying, distribution and modification follow. Pay
close attention to the difference between a "work based on the library" and
a "work that uses the library". The former contains code derived from
the library, whereas the latter must be combined with the library in order
to run.
GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. |
This License Agreement applies to any software library or other program which
contains a notice placed by the copyright holder or other authorized party saying it
may be distributed under the terms of this Lesser General Public License (also
called "this License"). Each licensee is addressed as "you". |
|
|
A "library" means a collection
of software functions and/or data prepared so as to be conveniently linked with application
programs (which use some of those functions and data) to form executables. The "Library",
below, refers to any such software library or work which has been distributed
under these terms. A "work based on the Library" means either the
Library or any derivative work under copyright law: that is to say, a
work containing the Library or a portion of it, either verbatim or with
modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation
in the term "modification".) "Source code" for a work means the preferred form
of the work for making modifications to it. For a library, complete
source code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to control compilation and installation
of the library. Activities other than copying, distribution and modification are not covered by
this License; they are outside its scope. The act of running a
program using the Library is not restricted, and output from such a program
is covered only if its contents constitute a work based on the Library
(independent of the use of the Library in a tool for writing it).
Whether that is true depends on what the Library does and what
the program that uses the Library does. |
1. |
You may copy and distribute verbatim copies
of the Library's complete source code as you receive it, in any medium,
provided that you conspicuously and appropriately publish on each copy an appropriate copyright
notice and disclaimer of warranty; keep intact all the notices that refer to
this License and to the absence of any warranty; and distribute a copy
of this License along with the Library. You may charge a fee for the
physical act of transferring a copy, and you may at your option offer
warranty protection in exchange for a fee. |
2. |
You may modify your copy or copies of
the Library or any portion of it, thus forming a work based on
the Library, and copy and distribute such modifications or work under the terms
of Section 1 above, provided that you also meet all of these conditions: |
|
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 combine or link a "work that uses the Library" with the
Library to produce a work containing portions of the Library, and distribute that
work under terms of your choice, provided that the terms permit modification of
the work for the customer's own use and reverse engineering for debugging such
modifications. You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are
covered by this License. You must supply a copy of this
License. If the work during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference directing
the user to the copy of this License. Also, you must do
one of these things: |
|
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. |
Use a suitable shared library mechanism for linking with
the Library. A suitable mechanism is one that (1) uses at run
time a copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2) will operate properly
with a modified version of the library, if the user installs one, as
long as the modified version is interface-compatible with the version that the work
was made with. |
|
c. |
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. |
|
d. |
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. |
|
e. |
Verify that the user has already received a copy of these materials or
that you have already sent this user a copy. |
|
For an executable, the required form
of the "work that uses the Library" must include any data and utility
programs needed for reproducing the executable from it. However, as a special
exception, the materials to be distributed need not include anything that is normally
distributed (in either source or binary form) with the major components (compiler, kernel, and
so on) of the operating system on which the executable runs, unless that
component itself accompanies the executable. It may happen that this requirement contradicts the
license restrictions of other proprietary libraries that do not normally accompany the operating system.
Such a contradiction means you cannot use both them and the Library
together in an executable that you distribute. |
7. |
You may place library facilities that are a
work based on the Library side-by-side in a single library together with other
library facilities not covered by this License, and distribute such a combined library,
provided that the separate distribution of the work based on the Library and
of the other library facilities is otherwise permitted, and provided that you do
these two things: |
|
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
with this License. |
11. |
If, as a consequence of a court judgment or allegation of
patent infringement or for any other reason (not limited to patent issues), conditions
are imposed on you (whether by court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from the conditions of
this License. If you cannot distribute so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as a consequence
you may not distribute the Library at all. For example, if a
patent license would not permit royalty-free redistribution of the Library by all those
who receive copies directly or indirectly through you, then the only way you could
satisfy both it and this License would be to refrain entirely from distribution
of the Library. If any portion of this section is held invalid or
unenforceable under any particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances. It
is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any such
claims; this section has the sole purpose of protecting the integrity of the
free software distribution system which is implemented by public license practices. Many
people have made generous contributions to the wide range of software distributed through that
system in reliance on consistent application of that system; it is up to
the author/donor to decide if he or she is willing to distribute software
through any other system and a licensee cannot impose that choice. This section is
intended to make thoroughly clear what is believed to be a consequence of
the rest of this License. |
12. |
If the distribution and/or use of the Library is
restricted in certain countries either by patents or by copyrighted interfaces, the original
copyright holder who places the Library under this License may add an explicit
geographical distribution limitation excluding those countries, so that distribution is permitted only in or
among countries not thus excluded. In such case, this License incorporates the
limitation as if written in the body of this License. |
13. |
The Free Software Foundation may
publish revised and/or new versions of the Lesser General Public License from time
to time. Such new versions will be similar in spirit to the present
version, but may differ in detail to address new problems or concerns. Each version
is given a distinguishing version number. If the Library specifies a version
number of this License which applies to it and "any later version", you
have the option of following the terms and conditions either of that version
or of any later version published by the Free Software Foundation. If
the Library does not specify a license version number, you may choose any
version ever published by the Free Software Foundation. |
14. |
If you wish to incorporate parts of
the Library into other free programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free Software Foundation; we
sometimes make exceptions for this. Our decision will be guided by the
two goals of preserving the free status of all derivatives of our free software
and of promoting the sharing and reuse of software generally. |

NO WARRANTY
15. |
BECAUSE THE LIBRARY
IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO
THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD
THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
CORRECTION. |
16. |
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL,
SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. |

END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be
of the greatest possible use to the public, we recommend making it free software
that everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the ordinary General
Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most
effectively convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what
it does.>

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

You should have received a copy of the GNU Lesser General Public License
along with this library; if not, write to the Free Software Foundation, Inc.,

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.

That's all there is to it!
