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:
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.)
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 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. |
