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:

    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.
