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 sur-
