Licences
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 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 preferred
form of the work for making modifications to it. For
an executable work, complete source code means
all the source code for all modules it contains, plus
any associated interface definition files, 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 are not
compelled to copy the source along with the object
code.
4. You may not copy, modify, sublicense, or distribute
the Program except as expressly provided 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. You are not required 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 redistribute 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. You may not impose any
further restrictions on the recipients’ exercise of the
rights granted herein.
You 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 receive copies directly or indirectly
through you, then the only way you could satisfy
both it and this License would be to refrain entirely
from 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 reliance 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 Program 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 Free 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 specifies 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 Program 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 are different, write to the author to ask
for permission. For software which is copyrighted
by the Free Software 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 software 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
STATED IN WRITING THE COPYRIGHT HOLDERS
AND/ OR OTHER PARTIES PROVIDE THE
PROGRAM “AS IS” WITHOUT WARRANTY OF
ANY KIND, EITHER EXPRESSED OR IMPLIED,
INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY
AND FITNESS FOR A PARTICULAR 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, REPAIR OR CORRECTION.
12.IN NO EVENT UNLESS REQUIRED BY
APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER
PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE PROGRAM AS PERMITTED ABOVE, BE
LIABLE TO YOU FOR DAMAGES, INCLUDING
ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF
THE USE OR INABILITY TO USE THE PROGRAM
(INCLUDING BUT NOT LIMITED TO LOSS OF DATA
OR DATA BEING RENDERED INACCURATE OR
LOSSES SUSTAINED BY YOU OR THIRD PARTIES
OR A FAILURE OF THE PROGRAM TO OPERATE
WITH ANY OTHER PROGRAMS), EVEN IF SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED
OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply 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 a brief
idea of what it does.>
Copyright © <year> <name of author>

or (at your option) any later version.
This program is distributed in the hope that it will
be useful, but WITHOUT ANY WARRANTY; without

not, write to the Free Software Foundation, Inc., 51
Franklin Street, Fifth Floor, Boston, MA 02110-1301

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 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
