If the program is interactive, make it output a
short notice like this when it starts in an inter-
active 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 in-
corporating your program into proprietary pro-
grams. If your program is a subroutine library,
you may consider it more useful to permit link-
ing 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

[This is the first released version of the Lesser

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 free-
dom 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 Soft-
ware Foundation and other authors who decide
to use it. You can use it too, but we suggest
you first think carefully about whether this li-
cense 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 refer-
ring 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 soft-
ware 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 re-
strictions 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 cop-
ies 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, re-
ceive or can get the source code. If you link
other code with the library, you must provide
