Licenses
date of any change.
b) Y ou 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 ther eof, to be
licensed as a whole at no charge to all third parties
under the terms of this License.
c) If the modifi ed pr ogram 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.)
These requirements apply to the modifi ed work as
a whole. If identifi able sections of that work are not
derived from the Program, and can be r easonably
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 wr ote 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. Y ou 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 sour ce code.
(This alternative is allowed only for noncommercial
distribution and only if you received the program in
object code or executable form with such an offer , in
accord with Subsection b above.)
The source code for a work means the preferr ed
form of the work for making modifi cations to it. For
an executable work, complete source code means all
the source code for all modules it contains, plus any
associated interface defi nition fi les, plus the scripts
used to control compilation and installation of the
executable. However , as a special exception, the
source code distributed need not include anything that
is normally distributed (in either source or binary form)
with the major components (compiler , kernel, and so
on) of the operating system on which the executable
runs, unless that component itself accompanies the
executable.
If distribution of executable or object code is made
by offering access to copy from a designated place,
then offering equivalent access to copy the source
code from the same place counts as distribution of
the source code, even though third parties ar e not
compelled to copy the source along with the object
code.
4. Y ou may not copy , modify , sublicense, or distribute
the Program except as expressly pr ovided under
this License. Any attempt otherwise to copy , modify ,
sublicense or distribute the Program is void, and will
automatically terminate your rights under this License.
However , parties who have received copies, or rights,
from you under this License will not have their licenses
terminated so long as such parties remain in full
compliance.
5. Y ou are not r equired to accept this License, since
you have not signed it. However , nothing else grants
you permission to modify or distribute the Program
or its derivative works. These actions are prohibited
by law if you do not accept this License. Therefore,
by modifying or distributing the Program (or any work
based on the Program), you indicate your acceptance
of this License to do so, and all its terms and
conditions for copying, distributing or modifying the
Program or works based on it.
6. Each time you r edistribute the Program (or any work
based on the Program), the recipient automatically
receives a license from the original licensor to copy ,
distribute or modify the Program subject to these
terms and conditions. Y ou may not impose any further
restrictions on the recipients’ exer cise of the rights
granted herein.
Y ou are not responsible for enforcing compliance by
third parties to this License.
7. If, as a consequence of a court judgment or allegation
of patent infringement or for any other reason (not
limited to patent issues), conditions are imposed on
you (whether by court order , agreement or otherwise)
that contradict the conditions of this License, they do
not excuse you from the conditions of this License. If
you cannot distribute so as to satisfy simultaneously
your obligations under this License and any other
pertinent obligations, then as a consequence you
may not distribute the Program at all. For example,
if a patent license would not permit royalty-free
redistribution of the Program by all those who r eceive
copies directly or indirectly thr ough you, then the only
way you could satisfy both it and this License would
be to refrain entirely fr om distribution of the Program.
If any portion of this section is held invalid or
unenforceable under any particular circumstance,
the balance of the section is intended to apply and
the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to
infringe any patents or other property right claims or
to contest validity of any such claims; this section has
the sole purpose of protecting the integrity of the free
software distribution system, which is implemented
by public license practices. Many people have
made generous contributions to the wide range of
software distributed through that system in r eliance
on consistent application of that system; it is up to
the author/donor to decide if he or she is willing to
distribute software through any other system and a
licensee cannot impose that choice.
This section is intended to make thoroughly clear what
is believed to be a consequence of the rest of this
License.
8. If the distribution and/or use of the Pr ogram is
restricted in certain countries either by patents or by
copyrighted interfaces, the original copyright holder
who places the Program under this License may add
an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in
or among countries not thus excluded. In such case,
this License incorporates the limitation as if written in
the body of this License.
9. The Fr ee Software Foundation may publish revised
and/ or new versions of the General Public License
from time to time. Such new versions will be similar in
spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number .
If the Program specifi es a version number of this
License which applies to it and “any later version”, you
have the option of following the terms and conditions
either of that version or of any later version published
by the Free Software Foundation. If the Pr ogram does
not specify a version number of this License, you
may choose any version ever published by the Free
Software Foundation.
10. If you wish to incorporate parts of the Program into
other free programs whose distribution conditions ar e
different, write to the author to ask for permission. For
software which is copyrighted by the Free Softwar e
Foundation, write to the Free Software Foundation;
we sometimes make exceptions for this. Our decision
will be guided by the two goals of preserving the free
status of all derivatives of our free software and of
promoting the sharing and reuse of softwar e generally .
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE
OF CHARGE, THERE IS NO WARRANTY FOR
THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW . EXCEPT WHEN OTHERWISE
ST ATED IN WRITING THE COPYRIGHT HOLDERS
AND/ OR OTHER P ARTIES PROVIDE THE PROGRAM
“AS IS” WITHOUT WARRANTY OF ANY KIND,
EITHER EXPRESSED OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
OF MERCHANT ABILITY AND FITNESS FOR A
P ARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE
PROGRAM IS WITH YOU. SHOULD THE PROGRAM
PROVE DEFECTIVE, YOU ASSUME THE COST
OF ALL NECESSARY SERVICING, REP AIR OR
CORRECTION.
12.IN NO EVENT UNLESS REQUIRED BY APPLICABLE
LAW OR AGREED TO IN WRITING WILL ANY
COPYRIGHT HOLDER, OR ANY OTHER P ARTY
WHO MA Y MODIFY AND/OR REDISTRIBUTE THE
PROGRAM AS PERMITTED ABOVE, BE LIABLE TO
YOU FOR DAMAGES, INCLUDING ANY GENERAL,
SPECIAL, INCIDENT AL OR CONSEQUENTIAL
DAMAGES ARISING OUT OF THE USE OR INABILITY
TO USE THE PROGRAM (INCLUDING BUT NOT
LIMITED TO LOSS OF DA TA OR DA T A BEING
RENDERED INACCURA TE OR LOSSES SUSTAINED
BY YOU OR THIRD P ARTIES OR A FAILURE OF
THE PROGRAM TO OPERA TE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
P ARTY HAS BEEN ADVISED OF THE POSSIBILITY
OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These T erms to Y our 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.
T o do so, attach the following notices to the program. It
is safest to attach them to the start of each source fi le to
most effectively convey the exclusion of warranty; and
each fi le 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 a brief idea
of what it does.>
Copyright © <year> <name of author>
This program is free softwar e; you can redistribute it
and/ or modify it under the terms of the GNU General
Public License as published by the Free Software
Foundation; either version 2 of the License, or (at your
option) any later version.
This program is distributed in the hope that it will
be useful, but WITHOUT ANY WARRANTY ; without
even the implied warranty of MERCHANT ABILITY or
FITNESS FOR A P ARTICULAR PURPOSE. See the
GNU General Public License for more details.
Y ou should have received a copy of the GNU General
Public License along with this program; if not, write to
the Free Software Foundation, Inc., 51 Franklin Str eet,
Fifth Floor , Boston, MA 02110-1301 USA.
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 © year name of
author
Gnomovision comes with ABSOLUTEL Y NO
WARRANTY ; for details type ‘show w’. This is free
software, and you are welcome to r edistribute 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.
Y ou 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:
Y oyodyne, 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 pr ograms. 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.
