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 an idea of what it does.>

the commands you use may be called
something other than `show w' and `show

work as a programmer) or your school, if
any, to sign a "copyright disclaimer" for the

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 Lesser 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.

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

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,
