The hypothetical commands `show w' and `show c'
should show the appropriate parts of the General Public
License. Of course, the commands you use may be called
something other than `sho w w' and `show c'; they could
even be mouse -clicks or menu items – whatever suits
your program.
Y ou should also get your employer (if you wor k as a pro-
grammer) or your school, if any, to sign a "cop yright disc-
laimer" for the program, if necessary.
Here is a sample; alte r the names:
This General Public License does n ot permit incorpora-
ting your program into proprietary programs. If your pro-
gram is a subroutine library, y ou may consider it more
useful to permit link ing proprietar y applications with t he
librar y. If this is wh at you want to do, use the GNU Lesser
General P ublic Licen se inst ead of this Licens e.

Pream bl e
The licenses for most sof tware are designed to ta ke away
your freedom to share and change it. By contrast, the
GNU General Public Licenses are intended to guarantee
your freedom to share and change free software --to
make sure the software is free for all its users.
This license, the Lesser General Public License, applies to
some specially designated sof tware packages – typically
libraries – of the Free Software F oundation and othe r
authors who decide to use it. Y ou can use it too, but we
suggest you first think carefully about whether this
license or the ordinary General Public License is the bet-
ter strategy to use in any par ticular case, based on the
explanations below.
When we speak of free software, we are referring to free-
dom of use, not price. Our General Public Li censes are
designed to make sure that you have the freedom to dis-
tribute 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 infor-
med that you can do these things.
T o prot ect your rights, w e need to make rest rictions that
forbid distributors to deny you these rights or to ask you
to surrender these righ ts. These restricti ons translate into
certain responsibilities for you if you distribute copies of
the library or if you modify it.
Fo r example, if y ou distri bute copies of th e library, whe-
ther gratis or for a fee, you must give the recipient s all the
rights that we gav e you. Y ou must make sure that they ,
too, re ceive or can get the source code . If you link other
code with the library , you must provide complet e object
files to the recipie nts, so that they can rel ink them wit h
the library afte r making changes to the library and
recompiling it. And you must show them the se terms so
they know their rights .
We protect y our rights with a two-step method: (1) w e
copyright the library, and (2) we off e r you this license,
which gi ves you le gal permissio n to copy , distri bute and/
or modify the library.
T o p ro te c t e a ch d is tr i bu to r, we w an t t o ma ke i t ver y cl e ar
that there is no warranty for the free librar y. Also , if the
library is modi fied by someone else and passed on, the
recipients should know that wh at they have is not th e ori-
ginal version, so that the original author's reputation will
not be affected by problems that migh t be introduced by
others.
Finally , softwa re patents pose a con stant threat to the
ex i s t en c e of a ny f r e e p r o gr a m . We w i s h t o m a k e s u re t h a t
a company cannot effectively restrict the users of a free
program by obtaining a restrictive lic e nse from a pate nt
holder . Ther efore, w e insist th at any patent l icense obtai-
ned for a version of the libr ary must be consistent with
the full freedom of use specified in this license.
Most GNU soft ware, including some libraries, is covered
by the ordinar y GNU General Public License. Thi s license,
the GNU Lesser General Public License, applies to certain
designat ed libraries, an d is quite differe nt from the ordi-
nary General Public Li cense. We use this license for cer-
tain libraries in order to permit link ing those libraries into
non-free pr ograms.
When a program is linked with a library, whether statically
or using a shared library, the c o mbination of the two is
legally speaking a combined work, a derivative of the ori-
ginal library . The ordinary General P ublic License there-
fore permits such link ing only if the entire combination
fits its criteria of freedom . The Lesser General Public
License permits mor e lax criteria for linking other code
with the libr ary.
We call this license the "Lesser" General Public License
because it does Less to protect the user's freedom than
t h e o r d i n a r y G e n e r a l P u b l i c L i c e n s e . I t a l s o p r o v i d e s o th e r
free software developers Less of an advantage over com-
peting non-free programs. These disadvantages are the
reason w e use the ordinary General Public License for
many libraries. However , the Lesser licens e provides
advantages in certain special circumstances.
For example , on rare occasions, ther e may be a special
need to e ncourag e the widest possi ble use of a certain
library, so that it becomes a de-facto standard . T o achieve
this, non-fr ee programs must be allow ed to use the
library. A more frequent case is that a free library does the
same job as widely used non-free libr aries. In this case,
there is little to gain by limiting t he free librar y to free
softwa re only , so we use the Lesser Gen eral Public
License.
In other cases, permission to use a par ticular library in
non-free pr ograms enables a greate r number of people
to use a large body of fr e e software. F o r example, permis-
sion to use the G NU C Librar y in non-free programs enab-
les many more peopl e to use the whole GNU operating
system, as well as its variant, the GNU/Linux operating
syst em.
Although th e Lesser Gene ral Pu blic License is Less prot ec-
tive of the users' freedom, it does ensure that the user of
a program tha t is linked with the Library has the freedom
and the wher ewithal to run that program u sing a modi-
fied version of the Librar y.
