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.
