<title>GNU General Public License</title>

<sect1>
<title>Preamble</title>
<para>
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.
</para>
<para>
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.
</para>
<para>
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.
</para>
<para>
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.
</para>
<para>
We protect your rights with two steps:
<orderedlist>
<listitem>
<para>
copyright the software, and
</para>
</listitem>
<listitem>
<para>
offer you this license which gives you legal permission to copy, distribute
and/or modify the software.
</para>
</listitem>
</orderedlist>
</para>
<para>
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.
</para>
<para>
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.
</para>
<para>
The precise terms and conditions for copying, distribution and modification 
follow.
</para>
</sect1>

<sect1>
<title>TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</title>

<sect2>
<title>Section 0</title>
<para>
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".
</para>
<para>
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.
</para>
</sect2>

<sect2 id="sect1">
<title>Section 1</title>
<para>
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.
</para>
<para>
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.
</para>
</sect2>

<sect2 id="sect2">
<title>Section 2</title>
<para>
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
<link linkend="sect1">Section 1</link> above, provided 
that you also meet all of these conditions:
<orderedlist>
<listitem>
<para>
You must cause the modified files to carry prominent notices stating that 
you changed the files and the date of any change.
</para>
</listitem>
<listitem>
<para>
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.
</para>
</listitem>
<listitem>
<para>
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. 
<note>
<title>Exception:</title>
<para>
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.) 
</para>
</note>
</para>
</listitem>
</orderedlist>
</para>
<para>
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.
</para>
<para>
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.
</para>
<para>
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.
</para>
</sect2>

<sect2>
<title>Section 3</title>
<para>
You may copy and distribute the Program (or a work based on it, under 
<link linkend="sect2">Section 2
</link> in object code or executable form under the terms of 
<link linkend="sect1">Sections 1
</link> and 
<link linkend="sect2">2
</link> above provided that you also do one of the following:
<orderedlist>
<listitem>
<para>
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,
</para>
</listitem>
<listitem>
<para>
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,
</para>
</listitem>
<listitem>
<para>
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.)
</para>
</listitem>
</orderedlist>
</para>
<para>
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.
</para>
<para>
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.
</para>
</sect2>

<sect2>
<title>Section 4</title>
<para>
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.
</para>
</sect2>

<sect2>
<title>Section 5</title>
<para>
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.
</para>
</sect2>

<sect2>
<title>Section 6</title>
<para>
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.
</para>
</sect2>

<sect2>
<title>Section 7</title>
<para>
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.
</para>
<para>
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.
</para>
<para>
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.
</para>
<para>
This section is intended to make thoroughly clear what is believed to be a
consequence of the rest of this License.
</para>
</sect2>

<sect2>
<title>Section 8</title>
<para>
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.
</para>
</sect2>

<sect2>
<title>Section 9</title>
<para>
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.
</para>
<para>
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.
</para>
</sect2>

<sect2>
<title>Section 10</title>
<para>
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.
</para>
</sect2>

<sect2>
<title>NO WARRANTY Section 11</title>
<para>
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.
</para>
</sect2>

<sect2>
<title>Section 12</title>
<para>
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.

<title>How to Apply These Terms to Your New Programs</title>
<para>
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.
</para>
<para>
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.
</para>
<para>
&lt;one line to give the program's name and a brief idea of what it does.&gt;
Copyright (C) &lt;year&gt;    &lt;name of author&gt;
</para>
<para>
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.
</para>
<para>
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.
</para>
<para>
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., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
</para>
<para>
Also add information on how to contact you by electronic and paper mail.
</para>
<para>
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
</para>
<para>
Gnomovision version 69, Copyright (C) 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.
</para>
<para>
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.
</para>
<para>
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:
</para>
<para>
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.

<para>
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.
