This is the notice of license and warranty for ASCEND IV.
The authors of ASCEND will consider other licensing arrangements 
on a case-by-case basis.  This license applies to all ASCEND
interface, compiler, and solver programs, but not to third
party software subsystems (Tcl/Tk/solving codes) that we
may call.

             GNU GENERAL PUBLIC LICENSE
                Version 2, June 1991

Copyright (C) 1989, 1991
Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA

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.

    GNU GENERAL PUBLIC LICENSE
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.

    NO WARRANTY

  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.

  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.

     END OF TERMS AND CONDITIONS


How to Apply These Terms to Your New Programs

  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.

  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.

/*
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy  <name of author>

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.

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.

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., 675 Mass Ave, Cambridge, MA 02139, USA.
*/

Also add information on how to contact you by electronic
and paper mail.

If the program is interactive, make it output a short
notice like this when it starts in an interactive mode:


    Gnomovision version 69, Copyright (C) 19yy 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.

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.

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:

  Yoyodyne, Inc., hereby disclaims all copyright interest
  in the program `Gnomovision' (which makes passes at
  compilers) written by James Hacker.

  <signature of Ty Coon>, 1 April 1989
  Ty Coon, President of Vice

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.

19			Preamble
20
21			The licenses for most software are designed to take away
22			your freedom to share and change it. By contrast, the GNU
23			General Public License is intended to guarantee your
24			freedom to share and change free software--to make sure the
25			software is free for all its users. This General Public
26			License applies to most of the Free Software Foundation's
27			software and to any other program whose authors commit to
28			using it. (Some other Free Software Foundation software is
29			covered by the GNU Library General Public License
30			instead.) You can apply it to your programs, too.
31
32			When we speak of free software, we are referring to
33			freedom, not price. Our General Public Licenses are
34			designed to make sure that you have the freedom to
35			distribute copies of free software (and charge for this
36			service if you wish), that you receive source code or can
37			get it if you want it, that you can change the software or
38			use pieces of it in new free programs; and that you know
39			you can do these things.
40
41			To protect your rights, we need to make restrictions that
42			forbid anyone to deny you these rights or to ask you to
43			surrender the rights. These restrictions translate to
44			certain responsibilities for you if you distribute copies

46
47			For example, if you distribute copies of such a program,
48			whether gratis or for a fee, you must give the recipients
49			all the rights that you have. You must make sure that
50			they, too, receive or can get the source code. And you
51			must show them these terms so they know their rights.
52
53			We protect your rights with two steps: (1) copyright the
54			software, and (2) offer you this license which gives you
55			legal permission to copy, distribute and/or modify the
56			software.
57
58			Also, for each author's protection and ours, we want to
59			make certain that everyone understands that there is no

77			GNU GENERAL PUBLIC LICENSE
78			TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND
79			MODIFICATION
80
81			0. This License applies to any program or other work
82			which contains a notice placed by the copyright holder
83			saying it may be distributed under the terms of this
84			General Public License. The "Program", below, refers to
85			any such program or work, and a "work based on the Program"
86			means either the Program or any derivative work under
87			copyright law: that is to say, a work containing the
88			Program or a portion of it, either verbatim or with
89			modifications and/or translated into another language.
90			(Hereinafter, translation is included without limitation in
91			the term "modification".) Each licensee is addressed as
92			"you".
93
94			Activities other than copying, distribution and
95			modification are not covered by this License; they are
96			outside its scope. The act of running the Program is not
97			restricted, and the output from the Program is covered only
98			if its contents constitute a work based on the Program
99			(independent of having been made by running the Program).
100			Whether that is true depends on what the Program does.
101
102			1. You may copy and distribute verbatim copies of the
103			Program's source code as you receive it, in any medium,
104			provided that you conspicuously and appropriately publish
105			on each copy an appropriate copyright notice and disclaimer
106			of warranty; keep intact all the notices that refer to this
107			License and to the absence of any warranty; and give any
108			other recipients of the Program a copy of this License
109			along with the Program.
110
111			You may charge a fee for the physical act of transferring a
112			copy, and you may at your option offer warranty protection
113			in exchange for a fee.
114
115			2. You may modify your copy or copies of the Program or
116			any portion of it, thus forming a work based on the
117			Program, and copy and distribute such modifications or work
118			under the terms of Section 1 above, provided that you also
119			meet all of these conditions:
120
121			a) You must cause the modified files to carry prominent
122			notices stating that you changed the files and the date
123			of any change.
124
125			b) You must cause any work that you distribute or
126			publish, that in whole or in part contains or is
127			derived from the Program or any part thereof, to be
128			licensed as a whole at no charge to all third parties
129			under the terms of this License.
130
131			c) If the modified program normally reads commands
132			interactively when run, you must cause it, when started
133			running for such interactive use in the most ordinary
134			way, to print or display an announcement including an
135			appropriate copyright notice and a notice that there is
136			no warranty (or else, saying that you provide a
137			warranty) and that users may redistribute the program
138			under these conditions, and telling the user how to
139			view a copy of this License. (Exception: if the
140			Program itself is interactive but does not normally
141			print such an announcement, your work based on the
142			Program is not required to print an announcement.)
143
144			These requirements apply to the modified work as a whole.
145			If identifiable sections of that work are not derived from
146			the Program, and can be reasonably considered independent
147			and separate works in themselves, then this License, and
148			its terms, do not apply to those sections when you
149			distribute them as separate works. But when you distribute
150			the same sections as part of a whole which is a work based
151			on the Program, the distribution of the whole must be on
152			the terms of this License, whose permissions for other
153			licensees extend to the entire whole, and thus to each and
154			every part regardless of who wrote it.
155
156			Thus, it is not the intent of this section to claim rights
157			or contest your rights to work written entirely by you;
158			rather, the intent is to exercise the right to control the
159			distribution of derivative or collective works based on the
160			Program.
161
162			In addition, mere aggregation of another work not based on
163			the Program with the Program (or with a work based on the
164			Program) on a volume of a storage or distribution medium
165			does not bring the other work under the scope of this
166			License.
167
168			3. You may copy and distribute the Program (or a work
169			based on it, under Section 2) in object code or executable
170			form under the terms of Sections 1 and 2 above provided
171			that you also do one of the following:
172
173			a) Accompany it with the complete corresponding
174			machine-readable source code, which must be distributed
175			under the terms of Sections 1 and 2 above on a medium
176			customarily used for software interchange; or,
177
178			b) Accompany it with a written offer, valid for at
179			least three years, to give any third party, for a
180			charge no more than your cost of physically performing
181			source distribution, a complete machine-readable copy
182			of the corresponding source code, to be distributed
183			under the terms of Sections 1 and 2 above on a medium
184			customarily used for software interchange; or,
185
186			c) Accompany it with the information you received as to
187			the offer to distribute corresponding source code.
188			(This alternative is allowed only for noncommercial
189			distribution and only if you received the program in
190			object code or executable form with such an offer, in
191			accord with Subsection b above.)
192
193			The source code for a work means the preferred form of the
194			work for making modifications to it. For an executable
195			work, complete source code means all the source code for
196			all modules it contains, plus any associated interface
197			definition files, plus the scripts used to control
198			compilation and installation of the executable. However,
199			as a special exception, the source code distributed need
200			not include anything that is normally distributed (in
201			either source or binary form) with the major components
202			(compiler, kernel, and so on) of the operating system on
203			which the executable runs, unless that component itself
204			accompanies the executable.
205
206			If distribution of executable or object code is made by
207			offering access to copy from a designated place, then
208			offering equivalent access to copy the source code from the
209			same place counts as distribution of the source code, even
210			though third parties are not compelled to copy the source
211			along with the object code.
212
213			4. You may not copy, modify, sublicense, or distribute
214			the Program except as expressly provided under this
215			License. Any attempt otherwise to copy, modify, sublicense
216			or distribute the Program is void, and will automatically
217			terminate your rights under this License. However, parties
218			who have received copies, or rights, from you under this
219			License will not have their licenses terminated so long as
220			such parties remain in full compliance.
221
222			5. You are not required to accept this License, since you
223			have not signed it. However, nothing else grants you
224			permission to modify or distribute the Program or its
225			derivative works. These actions are prohibited by law if
226			you do not accept this License. Therefore, by modifying or
227			distributing the Program (or any work based on the
228			Program), you indicate your acceptance of this License to
229			do so, and all its terms and conditions for copying,
230			distributing or modifying the Program or works based on
231			it.
232
233			6. Each time you redistribute the Program (or any work
234			based on the Program), the recipient automatically receives
235			a license from the original licensor to copy, distribute or
236			modify the Program subject to these terms and conditions.
237			You may not impose any further restrictions on the
238			recipients' exercise of the rights granted herein. You are
239			not responsible for enforcing compliance by third parties
240			to this License.
241
242			7. If, as a consequence of a court judgment or allegation
243			of patent infringement or for any other reason (not limited
244			to patent issues), conditions are imposed on you (whether
245			by court order, agreement or otherwise) that contradict the
246			conditions of this License, they do not excuse you from the
247			conditions of this License. If you cannot distribute so as
248			to satisfy simultaneously your obligations under this
249			License and any other pertinent obligations, then as a
250			consequence you may not distribute the Program at all. For
251			example, if a patent license would not permit royalty-free
252			redistribution of the Program by all those who receive
253			copies directly or indirectly through you, then the only
254			way you could satisfy both it and this License would be to
255			refrain entirely from distribution of the Program.
256
257			If any portion of this section is held invalid or
258			unenforceable under any particular circumstance, the
259			balance of the section is intended to apply and the section
260			as a whole is intended to apply in other circumstances.
261
262			It is not the purpose of this section to induce you to
263			infringe any patents or other property right claims or to
264			contest validity of any such claims; this section has the
265			sole purpose of protecting the integrity of the free
266			software distribution system, which is implemented by
267			public license practices. Many people have made generous
268			contributions to the wide range of software distributed
269			through that system in reliance on consistent application
270			of that system; it is up to the author/donor to decide if
271			he or she is willing to distribute software through any
272			other system and a licensee cannot impose that choice.
273
274			This section is intended to make thoroughly clear what is
275			believed to be a consequence of the rest of this License.
276
277			8. If the distribution and/or use of the Program is
278			restricted in certain countries either by patents or by
279			copyrighted interfaces, the original copyright holder who
280			places the Program under this License may add an explicit
281			geographical distribution limitation excluding those
282			countries, so that distribution is permitted only in or
283			among countries not thus excluded. In such case, this
284			License incorporates the limitation as if written in the
285			body of this License.
286
287			9. The Free Software Foundation may
288			publish revised and/or new versions of the General Public
289			License from time to time. Such new versions will be
290			similar in spirit to the present version, but may differ in
291			detail to address new problems or concerns.
292
293			Each version is given a distinguishing version number. If
294			the Program specifies a version number of this License
295			which applies to it and "any later version", you have the
296			option of following the terms and conditions either of that
297			version or of any later version published by the Free
298			Software Foundation. If the Program does not specify a
299			version number of this License, you may choose any version
300			ever published by the Free Software Foundation.
301
302			10. If you wish to incorporate parts of the Program into
303			other free programs whose distribution conditions are
304			different, write to the author to ask for permission. For
305			software which is copyrighted by the Free Software
306			Foundation, write to the Free Software Foundation; we
307			sometimes make exceptions for this. Our decision will be
308			guided by the two goals of preserving the free status of
309			all derivatives of our free software and of promoting the
310			sharing and reuse of software generally.
311
312			NO WARRANTY
313
314			11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE
315			IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
316			APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING
317			THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE
318			PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
319			EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
320			IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
321			PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
322			PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
323			PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
324			SERVICING, REPAIR OR CORRECTION.
325
326			12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR
327			AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY
328			OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM
329			AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING
330			ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
331			ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
332			(INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
333			RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
334			PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY
335			OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS
336			BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
337
338			END OF TERMS AND CONDITIONS

342
343			How to Apply These Terms to Your New Programs
344
345			If you develop a new program, and you want it to be of
346			the greatest possible use to the public, the best way to
347			achieve this is to make it free software which everyone can
348			redistribute and change under these terms.
349
350			To do so, attach the following notices to the program.
351			It is safest to attach them to the start of each source
352			file to most effectively convey the exclusion of warranty;
353			and each file should have at least the "copyright" line and
354			a pointer to where the full notice is found.
355
356			/*
357			<one line to give the program's name and a brief idea of what it does.>
358			Copyright (C) 19yy <name of author>

360			This program is free software; you can redistribute it and/or modify
361			it under the terms of the GNU General Public License as published by

363			(at your option) any later version.
364
365			This program is distributed in the hope that it will be useful,
366			but WITHOUT ANY WARRANTY; without even the implied warranty of

371			along with this program; if not, write to the Free Software
372			Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
373			*/
374
375			Also add information on how to contact you by electronic
376			and paper mail.
377
378			If the program is interactive, make it output a short
379			notice like this when it starts in an interactive mode:
380
381
382			Gnomovision version 69, Copyright (C) 19yy name of author
383			Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
384			This is free software, and you are welcome to redistribute it
385			under certain conditions; type `show c' for details.
386
387			The hypothetical commands `show w' and `show c' should show
388			the appropriate parts of the General Public License. Of
389			course, the commands you use may be called something other
390			than `show w' and `show c'; they could even be mouse-clicks
391			or menu items--whatever suits your program.
392
393			You should also get your employer (if you work as a
394			programmer) or your school, if any, to sign a "copyright
395			disclaimer" for the program, if necessary. Here is a
396			sample; alter the names:
397
398			Yoyodyne, Inc., hereby disclaims all copyright interest
399			in the program `Gnomovision' (which makes passes at
400			compilers) written by James Hacker.

405			This General Public License does not permit incorporating
406			your program into proprietary programs. If your program is
407			a subroutine library, you may consider it more useful to
408			permit linking proprietary applications with the library.
409			If this is what you want to do, use the GNU Library General
410			Public License instead of this License.
