This product includes software licensed under the GNU
Lesser General Public License (LGPL) version 2.1. Source code for the open
source software may be obtained under the terms of the LGPL by sending a source
code request identifying the product and model to ipgopensourceinfo@hp.com. A
distribution fee may apply.
This license applies to the following component:
Version 2.1, February 1999
Copyright © 1991, 1999 Free Software Foundation, Inc.
51 Franklin Street, 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 Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
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.
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.
