GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301,
USA.
Everyone is permitted to copy and distribute verbatim
copies of this license document, but changing it is not
allowed.
Preamble
The licenses for most software are designed to
take away your freedom to share and change it. By
contrast, the GNU General Public License is intended
to guarantee your freedom to share and change free
software--to make sure the software is free for all its
users. This General Public License applies to most of the
Free Software Foundation's software and to any other
program whose authors commit to using it. (Some
other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can
apply it to your programs, 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 software, or if you modify it. For example, if you
distribute copies of such a program, whether gratis or
for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive
or can get the source code. And you must show them
these terms so they know their rights.
We protect your rights with two steps: (1) copyright the
software, and (2) offer you this license which gives you
legal permission to copy, distribute and/or modify the
software.
Also, for each author's protection and 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 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 original authors' reputations.
Finally, any free program is threatened constantly
by software patents. We wish to avoid the danger
that re-distributors of a free program will individually
obtain patent licenses, in effect making the program
proprietary. To prevent this, we have made it clear that
any patent must be licensed for everyone's free use or
not licensed at all.
The precise terms and conditions for copying,
distribution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION
AND MODIFICATION
This License applies to any program or other work which
contains a notice placed by the copyright holder saying
it may be distributed under the terms of this General
Public License. The 'Program' , below, refers to any such
program or work, and a 'work based on the Program'
means either the Program or any derivative work
under copyright law: that is to say, a work containing
the Program or a portion of it, either verbatim or with
modifications and/or translated into another language.
(Hereinafter, translation is included without limitation
in the term 'modification' . ) Each licensee is addressed as
'you' .
Activities other than copying, distribution and
modification are not covered by this License; they
are outside its scope. The act of running the Program
is not restricted, and the output from the Program is
covered only if its contents constitute a work based on
the Program (independent of having been made by
running the Program). Whether that is true depends on
what the Program does.
ENGLISH
1. You may copy and distribute verbatim copies of
the Program's source code as you receive it, in any
medium, provided that you conspicuously and
appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep
intact all the notices that refer to this License and
to the absence of any warranty; and give any other
recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of
transferring a copy, and you may at your option offer
warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program
or any portion of it, thus forming a work based
on the Program, and copy and distribute such
modifications or work under the terms of Section
1 above, provided that you also meet all of these
conditions:
A. You must cause the modified files to carry
prominent notices stating that you changed the
files and the date of any change.
B. You must cause any work that you distribute or
publish, that in whole or in part contains or is
derived from the Program or any part thereof, to
be licensed as a whole at no charge to all third
parties under the terms of this License.
C. If the modified program normally reads
commands interactively when run, you must
cause it, when started running for such interactive
use in the most ordinary way, to print or display
an announcement including an appropriate
copyright notice and a notice that there is no
warranty (or else, saying that you provide a
warranty) and that users may redistribute the
program under these conditions, and telling
the user how to view a copy of this License.
(Exception: if the Program itself is interactive but
does not normally print such an announcement,
your work based on the Program is not required
to print an announcement.)
EN-15
These requirements apply to the modified work as
a whole. If identifiable sections of that work are not
derived from the Program, and can be reasonably
considered independent and separate works in
themselves, then this License, and its terms, do not
apply to those sections when you distribute them as
separate works. But when you distribute the same
sections as part of a whole which is a work based on
the Program, the distribution of the whole must be
on the terms of this License, whose permissions for
other licensees extend to the entire whole, and thus
to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim
rights or contest your rights to work written entirely
by you; rather, the intent is to exercise the right to
control the distribution of derivative or collective
works based on the Program.
In addition, mere aggregation of another work not
based on the Program with the Program (or with
a work based on the Program) on a volume of a
storage or distribution medium does not bring the
other work under the scope of this License.
3. You may copy and distribute the Program (or a
work based on it, under Section 2) in object code
or executable form under the terms of Sections 1
and 2 above provided that you also do one of the
following:
A. Accompany it with the complete corresponding
machine readable source code, which must
be distributed under the terms of Sections 1
and 2 above on a medium customarily used for
software interchange; or,
B. Accompany it with a written offer, valid for at least
three years, to give any third party, for a charge
no more than your cost of physically performing
source distribution, a complete machine-
readable copy of the corresponding source code,
to be distributed under the terms of Sections 1
and 2 above on a medium customarily used for
software interchange; or,
C. Accompany it with the information you received
as to the offer to distribute corresponding source
code. (This alternative is allowed only for non-
commercial distribution and only if you received
