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. |

|
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. |

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.> |
