OSS Licenses
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 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 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 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 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.

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 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.>

This program is free software; 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 MERCHANTABILITY or
FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You 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 Street,

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 instead of this License.

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 freedom 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 Software Foundation and
other authors who decide to use it. You can use it too,
but we suggest you fi rst think carefully about whether
this license 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 referring to
freedom of use, not price. Our General Public Licenses
are designed to make sure that you have the freedom
