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
