You should also get your employer (if you work as a programmer) or your school, if any, to sign a „copyright disclaimer“ for the

program, if necessary. Here is a sample; alter the names:

This General Public License does not permit incorporating your program into proprietary programs. If your program is a subrou-

tine 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.

GNU LESSER GENERAL PUBLIC LICENSE

Version 2.1, February 1999

is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the rst re-

leased version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version

number 2.1.]

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 rst 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.
