Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.

Preamble

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:

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.
