Sony BDP-S280 - Manual (Page 14)

If your program is a subroutine library, you may
consider it more useful to permit linking proprietary
applications with the library. If this is what you want to
do, use the GNU Lesser General Public License instead
of this License.

Preamble
The licenses for most software are designed to take

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 Library General Public License,
applies to some specially designated Free Software
Foundation software, and to any other libraries whose
authors decide to use it. You can use it for your
libraries, too.
When we speak of free software, we are referring to
freedom, 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 or
use pieces of it in new free programs; and that you
know you can do these things.
To protect your rights, we need to make restrictions that
forbid anyone to deny you these rights or to ask you to
surrender the 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,
