8. If the distribution and/or use of the Program is restricted
in certain countries either by patents or by copyrighted
interfaces, the original copyright holder who places
the Program under this License may add an explicit
geographical distribution limitation excluding those
countries, so that distribution is permitted only in or
among countries not thus excluded. In such case, this
License incorporates the limitation as if written in the
body of this License.
9. The Free Software Foundation may publish revised
and/or new versions of the General Public License
from time to time. Such new versions will be similar in
spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number.
If the Program specifies a version number of this
License which applies to it and “any later version”, you
have the option of following the terms and conditions
either of that version or of any later version published
by the Free Software Foundation. If the Program does
not specify a version number of this License, you
may choose any version ever published by the Free
Software Foundation.
10. If you wish to incorporate parts of the Program into
other free programs whose distribution conditions are
different, write to the author to ask for permission. For
software which is copyrighted by the Free Software
Foundation, write to the Free Software Foundation;
we sometimes make exceptions for this. Our decision
will be guided by the two goals of preserving the free
status of all derivatives of our free software and of
promoting the sharing and reuse of software generally.

END OF TERMS AND CONDITIONS
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.
<one line to give the program’s name and a brief idea
of what it does.>

option) any later version.
This program is distributed in the hope that it will
be useful, but WITHOUT ANY WARRANTY; without

You should have received a copy of the GNU General
Public License along with this program; if not, write to
the Free Software Foundation, Inc., 51 Franklin Street,
Fifth Floor, Boston, MA 02110-1301 USA
Also add information on how to contact you by electronic
and paper mail.
If the program is interactive, make it output a short notice
like this when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of
author
Gnomovision comes with ABSOLUTELY NO
WARRANTY; for details type ‘show w’. This is free
software, and you are welcome to redistribute it under
certain conditions; type ‘show c’ for details.
The hypothetical commands ‘show w’ and ‘show c’
should show the appropriate parts of the General Public
License. Of course, the commands you use may be called
something other than ‘show w’ and ‘show c’; they could
even be mouse-clicks or menu items--whatever suits your
program.
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:
Yoyodyne, Inc., hereby disclaims all copyright interest

compilers) written by James Hacker.

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.

Everyone is permitted to copy and distribute verbatim
copies of this license document, but changing it is not
allowed.
[This is the first released 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 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.
Most GNU software, including some libraries, is covered
by the ordinary GNU General Public License. This license,
the GNU Lesser General Public License, applies to certain
designated libraries, and is quite different from the
ordinary General Public License. We use this license for
certain libraries in order to permit linking those libraries
into non-free programs.
When a program is linked with a library, whether statically or
using a shared library, the combination of the two is legally
speaking a combined work, a derivative of the original
library. The ordinary General Public License therefore
permits such linking only if the entire combination fits its
criteria of freedom. The Lesser General Public License
permits more lax criteria for linking other code with the
library.
We call this license the “Lesser” General Public License
because it does Less to protect the user’s freedom than
the ordinary General Public License. It also provides
other free software developers Less of an advantage over
competing non-free programs. These disadvantages are
the reason we use the ordinary General Public License
for many libraries. However, the Lesser license provides
advantages in certain special circumstances.
For example, on rare occasions, there may be a special
need to encourage the widest possible use of a certain
library, so that it becomes a de-facto standard. To achieve
this, non-free programs must be allowed to use the library.
A more frequent case is that a free library does the same
job as widely used non-free libraries. In this case, there
is little to gain by limiting the free library to free software
only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-
free programs enables a greater number of people to use
a large body of free software. For example, permission to
use the GNU C Library in non-free programs enables many
more people to use the whole GNU operating system, as
well as its variant, the GNU/Linux operating system.
Although the Lesser General Public License is Less
protective of the users’ freedom, it does ensure that the
user of a program that is linked with the Library has the
freedom and the wherewithal to run that program using a
modified version of the Library.
The precise terms and conditions for copying, distribution
and modification follow. Pay close attention to the
difference between a “work based on the library” and a
“work that uses the library”.
The former contains code derived from the library,
whereas the latter must be combined with the library in
order to run.
