/*GNU GENERAL PUBLIC LICENSE
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
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 Library 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 redistributors 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
0. 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.
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:
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.
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 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:
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,
medium
customarily used for software interchange; or,
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.
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.
Appendix: 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.

Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, 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:
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:

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 Library General
Public License instead of this License.*/
