<h2><a href="gpl.html#TOC1" name="SEC1">GNU GENERAL PUBLIC
LICENSE</a></h2>
<p>Version 2, June 1991 </p>
<pre>
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
</pre>
<h2><a href="gpl.html#TOC2" name="SEC2">Preamble</a></h2>
<p>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. </p>
<p>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. </p>
<p>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. </p>
<p>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. </p>
<p>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. </p>
<p>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. </p>
<p>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. </p>
<p>The precise terms and conditions for copying, distribution and
modification follow. </p>
<h2><a href="gpl.html#TOC3" name="SEC3">TERMS AND CONDITIONS FOR
COPYING, DISTRIBUTION AND MODIFICATION</a></h2>
<p><strong>0.</strong> 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". </p>
<p>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. </p>
<p><strong>1.</strong> 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. </p>
<p>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. </p>
<p><strong>2.</strong> 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: </p>
<ul>
<li><strong>a)</strong> You must cause the modified files to
carry prominent notices stating that you changed the
files and the date of any change. </li>
<li><strong>b)</strong> 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. </li>
<li><strong>c)</strong> 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.) </li>
</ul>
<p>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. </p>
<p>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. </p>
<p>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. </p>
<p><strong>3.</strong> 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: <!-- we use this doubled UL to get the sub-sections indented, --> <!-- while making the bullets as unobvious as possible. --> </p>
<ul>
<li><strong>a)</strong> 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, </li>
<li><strong>b)</strong> 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, </li>
<li><strong>c)</strong> 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.) </li>
</ul>
<p>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. </p>
<p>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. </p>
<p><strong>4.</strong> 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. </p>
<p><strong>5.</strong> 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. </p>
<p><strong>6.</strong> 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. </p>
<p><strong>7.</strong> 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. </p>
<p>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. </p>
<p>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. </p>
<p>This section is intended to make thoroughly clear what is
believed to be a consequence of the rest of this License. </p>
<p><strong>8.</strong> 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. </p>
<p><strong>9.</strong> 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. </p>
<p>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. </p>
<p><strong>10.</strong> 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. </p>
<p><strong>NO WARRANTY</strong></p>
<p><strong>11.</strong> 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.
</p>
<p><strong>12.</strong> 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. </p>
