1 jds 58 This is the notice of license and warranty for ASCEND IV.
2     The authors of ASCEND will consider other licensing arrangements
3     on a case-by-case basis. This license applies to all ASCEND
4     interface, compiler, and solver programs, but not to third
5     party software subsystems (Tcl/Tk/solving codes) that we
6     may call.

8     GNU GENERAL PUBLIC LICENSE
9     Version 2, June 1991
10    
11     Copyright (C) 1989, 1991
12     Free Software Foundation, Inc.
13     675 Mass Ave, Cambridge, MA 02139, USA
14    
15     Everyone is permitted to copy and distribute verbatim
16     copies of this license document, but changing it is not
17     allowed.
18    
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
45     of the software, or if you modify it.
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
60     warranty for this free software. If the software is
61     modified by someone else and passed on, we want its
62     recipients to know that what they have is not the original,
63     so that any problems introduced by others will not reflect
64     on the original authors' reputations.
65    
66     Finally, any free program is threatened constantly by
67     software patents. We wish to avoid the danger that
68     redistributors of a free program will individually obtain
69     patent licenses, in effect making the program proprietary.
70     To prevent this, we have made it clear that any patent must
71     be licensed for everyone's free use or not licensed at
72     all.
73    
74     The precise terms and conditions for copying, distribution
75     and modification follow.
76    
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
339    
340    
341    
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>
359    
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
362     the Free Software Foundation; either version 2 of the License, or
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
367     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
368     GNU General Public License for more details.
369    
370     You should have received a copy of the GNU General Public License
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.
401    
402     <signature of Ty Coon>, 1 April 1989
403     Ty Coon, President of Vice
404    
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.
