<P class=3DBody><A name=3DpgfId-1154449></A>Copyright =A9 1989, 1991 =
Free Software=20
Foundation, Inc.<BR>59 Temple Place, Suite 330, Boston, MA 02111-1307, =
USA</P>
<P class=3DBody><A name=3DpgfId-1154450></A>Everyone is permitted to =
copy and=20
distribute verbatim copies of this license document, but changing it is =
not=20
allowed.</P>
<H3 class=3DHeading2><A name=3DpgfId-1154453></A>Preamble</H3>
<P class=3DBody><A name=3DpgfId-1154454></A>The licenses for most =
software are=20
designed to take away your freedom to share and change it. By contrast, =
the GNU=20
General Public License is intended to guarantee your freedom to share =
and change=20
free software--to make sure the software is free for all its users. This =
General=20
Public License applies to most of the Free Software Foundation's =
software and to=20
any other program whose authors commit to using it. (Some other Free =
Software=20
Foundation software is covered by the GNU Library General Public License =
instead.) You can apply it to your programs, too.</P>
<P class=3DBody><A name=3DpgfId-1154455></A>When we speak of free =
software, we are=20
referring to freedom, not price. Our General Public Licenses are =
designed to=20
make sure that you have the freedom to distribute copies of free =
software (and=20
charge for this service if you wish), that you receive source code or =
can get it=20
if you want it, that you can change the software or use pieces of it in =
new free=20
programs; and that you know you can do these things.</P>
<P class=3DBody><A name=3DpgfId-1154456></A>To protect your rights, we =
need to make=20
restrictions that forbid anyone to deny you these rights or to ask you =
to=20
surrender the rights. These restrictions translate to certain =
responsibilities=20
for you if you distribute copies of the software, or if you modify =
it.</P>
<P class=3DBody><A name=3DpgfId-1154457></A>For example, if you =
distribute copies of=20
such a program, whether gratis or for a fee, you must give the =
recipients all=20
the rights that you have. You must make sure that they, too, receive or =
can get=20
the source code. And you must show them these terms so they know their=20
rights.</P>
<P class=3DBody><A name=3DpgfId-1154458></A>We protect your rights with =
two steps:=20
(1) copyright the software, and (2) offer you this license which gives =
you legal=20
permission to copy, distribute and/or modify the software.</P>
<P class=3DBody><A name=3DpgfId-1154459></A>Also, for each author's =
protection and=20
ours, we want to make certain that everyone understands that there is no =
warranty for this free software. If the software is modified by someone =
else and=20
passed on, we want its recipients to know that what they have is not the =
original, so that any problems introduced by others will not reflect on =
the=20
original authors' reputations.</P>
<P class=3DBody><A name=3DpgfId-1154460></A>Finally, any free program is =
threatened=20
constantly by software patents. We wish to avoid the danger that =
redistributors=20
of a free program will individually obtain patent licenses, in effect =
making the=20
program proprietary. To prevent this, we have made it clear that any =
patent must=20
be licensed for everyone's free use or not licensed at all.</P>
<P class=3DBody><A name=3DpgfId-1154692></A>The precise terms and =
conditions for=20
copying, distribution and modification follow.</P>
