How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to
make it free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is
found.

This General Public License does not permit incorporating your program into proprietary programs. 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 Library General Public License instead of this License.

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 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 users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist
that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license.
