The licenses for most software are designed to take away your freedom to share
and change it. By contrast, the GNU General Public Licenses are intended to guar-
antee
y
our freedom to share and chan
g
e free software--to make sure the software
i
s free for all its users
.
This license, the Lesser General Public License, applies to some specially designated
software packages--typically libraries--of the Free Software Foundation and othe
r
authors who decide to use it. You can use it too, but we suggest you À rst think
c
arefull
y
about whether this license or the ordinar
y
General Public License is the
b
etter strategy to use
i
n any part
i
cu

When we speak of free software, we are referring to freedom of use, not price.
O
ur General Public Licenses are designed to make sure that you have the freedom
t
o distribute copies of free software (and charge for this service if you wish)
;
t
hat
y
ou receive source code or can
g
et it if
y
ou want it; that
y
ou can chan
g
e the
software and use pieces of it in new free programs; and that you are informed that
y
ou can
d
o t
h
ese t
hi
ngs
.
To protect your rights, we need to make restrictions that forbid distributors to
d
en
y
y
ou t
h
ese r

ts or to as
k
y
ou to surren
d

ranslate to certain res
p
onsibilities for
y
ou if
y
ou distribute co
p
ies of the librar
y
o

i
f you modify it
.
For example, if you distribute copies of the library, whether gratis or for a fee, you
must g

p
i

Y
ou must ma
k
e sure t
h
at
t
he
y
, too, receive or can
g
et the source code. If
y
ou link other code with the librar
y,
y
ou must provide complete object À les to the recipients, so that they can relink
t
hem with the library after making changes to the library and recompiling it. And
y
ou must s

We protect your rights with a two-step method: (1) we copyright the library, and
(

)
we offer
y
ou this license, which
g
ives
y
ou le
g
al
p
ermission to co
py
, distribute
and/or modify the library
.
T

str
ib
utor, we want to ma
k
e
i
t very c
l
ear t
h
at t
h
ere

for the free library. Also, if the library is modiÀ ed by someone else and passed on

Finally, software patents pose a constant threat to the existence of any free pro-
gram. We wish to make sure that a company cannot effectively restrict the users
o
f a free
p
ro
g
ram b
y
obtainin
g
a restrictive license from a
p
atent holder. Therefore
,
we insist that an
y
p
atent license obtained for a version of the librar
y
must be
c
onsistent with the full freedom of use speciÀ ed in this license
.
Most GNU software, including some libraries, is covered by the ordinary GNU
G
eneral Public License. This license, the GNU Lesser General Public License, ap-
p
lies to certain desi
g
nated libraries, and is
q
uite different from the ordinar
y
General
P
ublic License. We use this license for certain libraries in order to
p
ermit linkin
g
t
hose libraries into non-free programs.

t
he combination of the two is legally speaking a combined work, a derivative of the
o
ri
g
inal librar
y
. The ordinar
y
General Public License therefore
p
ermits such linkin
g
o
nly if the entire combination À ts 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
t
o protect the user's freedom than the ordinary General Public License. It also
p
rovides other free software develo
p
ers Less of an advanta
g
e over com
p
etin
g
non-
free programs. These disadvantages are the reason we use the ordinary General
P
ublic License for many libraries. However, the Lesser license provides advantages

d
to encoura
g
e t
h
e
widest
p
ossible use of a certain librar
y
, so that it becomes a de-facto standard. To
achieve this, non-free
p
ro
g
rams must be allowed to use the librar
y
. A more fre-
quent 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,
p
ermission to use a
p
articular librar
y
in non-free
p
ro
g
rams enables
a
g
reater number of
p
eo
p
le to use a lar
g
e bod
y
of free software. For exam
p
le
,
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/
Li

.
Althou
g
h the Lesser General Public License is Less
p
rotective of the users' free-
d
om, it does ensure that the user of a
p
ro
g
ram that is linked with the Librar
y
has
t
he freedom and the wherewithal to run that program using a modiÀ ed version o
