work, complete source code means all

exception, the source code distributed
need not include anything that is
normally distributed (in either source or

components (compiler, kernel, an

the executable runs, unless that
component itself accompanies the

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 Ge
License, applies to some specially
designated software packa
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 w
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 distrib
you these rights or to ask you to surrender
these rights. These restrictions translate to
certain responsibilities fo
distribute copies of the library or if you
modify it.
For example, if you distribute copies of the
library, whet
give the recipients all the rights that we
gave you. You must make sure that they,

rights.
We protect your rights with a two-step
method: (1) we copyright the library, and (2)

make it very clear that there is no warr

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 obtaini
from a patent holder. Therefore, we insist
that any patent license obtained for a
version of the library must be
with the full freedom of use specified
license.
