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.
