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
