Preamble
The licenses for most software are designed to take away your freedo
m to share and change it. By contrast, the GNU General Public License
s are intended to guarantee your freedom to share and change free so
ftware--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some speciall
y designated software packages--typically libraries--of the Free Softwa
re Foundation and other authors who decide to use it. You can use it t
oo, but we suggest you first think carefully about whether this license
or the ordinary General Public License is the better strategy to use in a
ny particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use, n
ot price. Our General Public Licenses are designed to make sure that y
ou 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 t
hings.
To protect your rights, we need to make restrictions that forbid distrib
utors to deny you these rights or to ask you to surrender these rights.
These restrictions translate to certain responsibilities for you if you dist
ribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis or fo
r a fee, you must give the recipients all the rights that we gave you. Y
ou 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 obje
ct files to the recipients, so that they can relink them with the library a
fter making changes to the library and recompiling it. And you must sh
ow them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the li
brary, and (2) we offer you this license, which gives you legal permissi
on 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 some
one else and passed on, the recipients should know that what they ha
ve is not the original version, so that the original author's reputation w
ill not be affected by problems that might be introduced by others.
