<title>Terms and Conditions for Copying, Distribution and Modification</title>
<para>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''.</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>
<para>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.</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>
<para>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:</para>
<para>a) You must cause the modified files to carry prominent
notices stating that you changed the files and the date of any
change.</para>
<para>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.</para>
<para>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.)</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>
<para>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:</para>
<para>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,</para>
<para>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,</para>
<para>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.)</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>
<para>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.</para>
<para>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.</para>
<para>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.</para>
<para>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.</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>
<para>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.</para>
<para>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.</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>
<para>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.</para>
<para><emphasis>NO WARRANTY</emphasis></para>
<para>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.</para>
<para>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.</para>
