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 soft-
ware 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 soft-
ware. 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 sys-
tem.
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, dis-
tribution and modification follow. Pay close atten-
tion 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 authori-
zed 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 func-
tions and/or data prepared so as to be convenien-
tly linked with application programs (which use
some of those functions and data) to form execu-
tables.
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 "modifica-
tion".)
"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 installa-
tion 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 pro-
gram 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 conspicuo-
usly 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.
