Appendix
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 con-
tains 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 distrib-
uted 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.
