Foundation and other authors who
decide to use it. You can use it too, but
we suggest you first think carefully about
whether this license or the ordinary
General Public License is the better strat-
egy to use in any particular case, based
on the explanations below.
When we speak of free software, we are
referring to freedom of use, not price.
Our General Public Licenses are
designed to make sure that you have the
freedom to distribute copies of free soft-
ware (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
informed that you can do these things.
To protect your rights, we need to make
restrictions that forbid distributors to deny
you these rights or to ask you to surren-
der these rights. These restrictions trans-
late to certain responsibilities for you if
you distribute copies of the library or if
you modify it.
For example, if you distribute copies of
the library, whether gratis or for a fee,
you must give the recipients all the rights
that we gave you. You must make sure
that they, too, receive or can get the
source code. If you link other code with
the library, you must provide complete
object files to the recipients, so that they
can relink them with the library after mak-
ing changes to the library and recompil-
ing it. And you must show them these
terms so they know their rights.
We protect your rights with a two-step
method: (1) we copyright the library, and
(2) we offer you this license, which gives
you legal permission to copy, distribute
and/or modify the library.
To protect each distributor, we want to
make it very clear that there is no war-
ranty for the free library. Also, if the
library is modified by someone else and
passed on, the recipients should know
that what they have is not the original
version, so that the original author's repu-
tation will not be affected by problems
that might be introduced by others.
Finally, software patents pose a constant
threat to the existence of any free pro-
gram. We wish to make sure that a com-
pany cannot effectively restrict the users
of a free program by obtaining a restric-
tive license from a patent holder.
Therefore, we insist that any patent
license obtained for a version of the
library must be consistent with the full
freedom of use specified in this license.
Most GNU software, including some
libraries, is covered by the ordinary GNU
General Public License. This license, the
GNU Lesser General Public License,
applies to certain designated libraries,
and is quite different from the ordinary
General Public License. We use this
license for certain libraries in order to
permit linking those libraries into non-free
programs.
When a program is linked with a library,
whether statically or using a shared
library, the combination of the two is
legally speaking a combined work, a
derivative of the original library. The ordi-
nary General Public License therefore
permits such linking only if the entire
combination fits its criteria of freedom.
The Lesser General Public License per-
mits more lax criteria for linking other
code with the library.
We call this license the "Lesser" General
Public License because it does Less to
protect the user's freedom than the ordi-
nary General Public License. It also pro-
vides other free software developers
Less of an advantage over competing
non-free programs. These disadvantages
are the reason we use the ordinary
General Public License for many
libraries. However, the Lesser license
provides advantages in certain special
circumstances.
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 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, permission to use a par-
ticular library in non-free programs
