How to
Ap·piy
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 an idea
of
what it does.>

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
in the program 'Gnomovision' (which makes passes at
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 Lesser General
Public
License instead
of
this License.

Copyright, (C)

Free
Software Foundation, Inc.
675 Mass
Ave,
Cambridge, MA

USA
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 library
GPL.
It
is numbered 2 because it goes with version 2
of
the
ordinary
GPL.]
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 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,
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
a program 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.
Our
method
of
protecting your rights has two steps: (
1)
copyright the library, and (2) offer you this license
which gives you legal permission
to
copy, distribute
and/or modify the library.
Also, for each distributor's protection, we want to make
certain that everyone understands that there
is
no
warranty for this free library . .If the library
is
modified
by someone else and passed on, we want its recipients
to know that what they have is not the original version,
so that any problems introduced by others will not
reflect on the original authors' reputations.
Finally, any free program
is
threatened constantly by
software patents. We wish to avoid the danger that
companies distributing free software will individually
obtain patent licenses, thus in effect transforming the
program into proprietary software. To prevent this, we
have made it clear that any patent must be licensed for
everyone's free use or not licensed at all.
