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.<BR>
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.

<LI>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.
<LI>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.
<LI>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.
<LI>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.
<BR>
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.<BR>
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.<BR>
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.<BR>
This section is intended to make thoroughly clear what is believed
to be a consequence of the rest of this License.
<LI>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.
<LI>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.
<BR>
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.
<LI>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.

<LI>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,

PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
SERVICING, REPAIR OR CORRECTION.
<LI>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>
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.
<P>
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.

<P>
This program is distributed in the hope that it will be useful,

You should have received a copy of the GNU General Public License

<P>
Also add information on how to contact you by electronic and paper
mail.
<P>
If the program is interactive, make it output a short notice like
this when it starts in an interactive mode:
<P>
Gnomovision version 69, Copyright (C) 19__ name of author Gnomovision
comes with ABSOLUTELY NO WARRANTY; for details type "show
w."
<P>
This is free software, and you are welcome to redistribute it
under certain conditions; type "show c" for details.
<P>
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.
<P>
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:

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.

<P>
The intent of this document is to state the conditions under which
a Package may be copied, such that the Copyright Holder maintains
some semblance of artistic control over the development of the
package, while giving the users of the package the right to use
and distribute the Package in a more-or-less customary fashion,
plus the right to make reasonable modifications.
<H3><A NAME="Definitions">
Definitions</A></H3>
<P>
"Package" refers to the collection of files distributed
by the Copyright Holder, and derivatives of that collection of
files created through textual modification.
<P>
"Standard Version" refers to such a Package if it has
not been modified, or has been modified in accordance with the
wishes of the Copyright Holder as specified below.
<P>
"Copyright Holder" is whoever is named in the copyright
or copyrights for the package.
<P>
"You" is you, if you're thinking about copying or distributing
this Package.
<P>
"Reasonable copying fee" is whatever you can justify
on the basis of media cost, duplication charges, time of people
involved, and so on. (You will not be required to justify it to
the Copyright Holder, but only to the computing community at large
as a market that must bear the fee.)
<P>
"Freely Available" means that no fee is charged for
the item itself, though there may be fees involved in handling
the item.
<P>
It also means that recipients of the item may redistribute it
under the same conditions they received it.
<OL>
<LI>You may make and give away verbatim copies of the source form
of the Standard Version of this Package without restriction, provided
that you duplicate all of the original copyright notices and associated
disclaimers.
<LI>You may apply bug fixes, portability fixes and other modifications
derived from the Public Domain or from the Copyright Holder. A
Package modified in such a way shall still be considered the Standard
Version.
<LI>You may otherwise modify your copy of this Package in any
way, provided that you insert a prominent notice in each changed
file stating how and when you changed that file, and provided
that you do at least <I>one</I> of the following:
</OL>
<P>
<ol>
<OL type=a>
<LI>Place your modifications in the Public Domain or otherwise
make them Freely Available, such as by posting said modifications
to Usenet or an equivalent medium, or placing the modifications
on a major archive site such as uunet.uu.net, or by allowing the
Copyright Holder to include your modifications in the Standard
Version of the Package.
<LI>Use the modified Package only within your corporation or organization.
<LI>Rename any nonstandard executables so the names do not conflict
with standard executables, which must also be provided, and provide
a separate manual page for each nonstandard executable that clearly
documents how it differs from the Standard Version.
<LI>Make other distribution arrangements with the Copyright Holder.
</OL>
</ol>
<P>
<OL start=4>
<LI>You may distribute the programs of this Package in object
code or executable form, provided that you do at least ONE of
the following:
</OL>
<P>
<ol>
<OL type=a>
<LI>Distribute a Standard Version of the executables and library
files, together with instructions (in the manual page or equivalent)
on where to get the Standard Version.
<LI>Accompany the distribution with the machine-readable source
of the Package with your modifications.
<LI>Give nonstandard executables nonstandard names, and clearly
document the differences in manual pages (or equivalent), together
with instructions on where to get the Standard Version.
<LI>Make other distribution arrangements with the Copyright Holder.
</OL>
</ol>
<P>
<OL start=5>
<LI>You may charge a reasonable copying fee for any distribution
of this Package. You may charge any fee you choose for support
of this Package. You may not charge a fee for this Package itself.
However, you may distribute this Package in aggregate with other
(possibly commercial) programs as part of a larger (possibly commercial)
software distribution provided that you do not advertise this
Package as a product of your own. You may embed this Package's
interpreter within an executable of yours (by linking); this shall
be construed as a mere form of aggregation, provided that the
complete Standard Version of the interpreter is so embedded.
<LI>The scripts and library files supplied as input to or produced
as output from the programs of this Package do not automatically
fall under the copyright of this Package, but belong to whomever
generated them, and may be sold commercially, and may be aggregated
with this Package. If such scripts or library files are aggregated
with this Package via the so-called "undump" or "unexec"
methods of producing a binary executable image, then distribution
of such an image shall neither be construed as a distribution
of this Package nor shall it fall under the restrictions of Paragraphs
3 and 4, provided that you do not represent such an executable
image as a Standard Version of this Package.
<LI>C subroutines (or comparably compiled subroutines in other
languages) supplied by you and linked into this Package in order
to emulate subroutines and variables of the language defined by
this Package shall not be considered part of this Package, but
are the equivalent of input as in Paragraph 6, provided these
subroutines do not change the language in any way that would cause
it to fail the regression tests for the language.
<LI>Aggregation of this Package with a commercial distribution
is always permitted provided that the use of this Package is embedded;
that is, when no overt attempt is made to make this Package's
interfaces visible to the end user of the commercial distribution.
Such use shall not be construed as a distribution of this Package.
<LI>The name of the Copyright Holder may not be used to endorse
or promote products derived from this software without specific
prior written permission.
<LI>THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY
EXPRESS OR IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION,
THE IMPLIED WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR
PURPOSE.
