Preamble

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 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 software
packages--typically libraries--of the
Free Software 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 strategy
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 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 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 surrender these
rights. These restrictions translate 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
making changes to the library and
recompiling 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
warranty 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 reputation 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 program. We wish to make
sure that a company cannot
effectively restrict the users of a free
program by obtaining a restrictive
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 ordinary
General Public License therefore
permits such linking only if the
entire combination fits 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 to protect the user's
freedom than the ordinary General
Public License. It also provides 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 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
