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

22 # GNU GENERAL PUBLIC LICENSE
23 # Version 2, June 1991
24
25 # Copyright (C) 1989, 1991
26 # Free Software Foundation, Inc.
27 # 675 Mass Ave, Cambridge, MA 02139, USA
28
29 # Everyone is permitted to copy and distribute verbatim
30 # copies of this license document, but changing it is not
31 # allowed.
32
33 # Preamble
34
35 # The licenses for most software are designed to take away
36 # your freedom to share and change it. By contrast, the GNU
37 # General Public License is intended to guarantee your
38 # freedom to share and change free software--to make sure the
39 # software is free for all its users. This General Public
40 # License applies to most of the Free Software Foundation's
41 # software and to any other program whose authors commit to
42 # using it. (Some other Free Software Foundation software is
43 # covered by the GNU Library General Public License
44 # instead.) You can apply it to your programs, too.
45
46 # When we speak of free software, we are referring to
47 # freedom, not price. Our General Public Licenses are
48 # designed to make sure that you have the freedom to
49 # distribute copies of free software (and charge for this
50 # service if you wish), that you receive source code or can
51 # get it if you want it, that you can change the software or
52 # use pieces of it in new free programs; and that you know
53 # you can do these things.
54
55 # To protect your rights, we need to make restrictions that
56 # forbid anyone to deny you these rights or to ask you to
57 # surrender the rights. These restrictions translate to
58 # certain responsibilities for you if you distribute copies
59 # of the software, or if you modify it.
60
61 # For example, if you distribute copies of such a program,
62 # whether gratis or for a fee, you must give the recipients
63 # all the rights that you have. You must make sure that
64 # they, too, receive or can get the source code. And you
65 # must show them these terms so they know their rights.
66
67 # We protect your rights with two steps: (1) copyright the
68 # software, and (2) offer you this license which gives you
69 # legal permission to copy, distribute and/or modify the
70 # software.
71
72 # Also, for each author's protection and ours, we want to
73 # make certain that everyone understands that there is no
74 # warranty for this free software. If the software is
75 # modified by someone else and passed on, we want its
76 # recipients to know that what they have is not the original,
77 # so that any problems introduced by others will not reflect
78 # on the original authors' reputations.
79
80 # Finally, any free program is threatened constantly by
81 # software patents. We wish to avoid the danger that
82 # redistributors of a free program will individually obtain
83 # patent licenses, in effect making the program proprietary.
84 # To prevent this, we have made it clear that any patent must
85 # be licensed for everyone's free use or not licensed at
86 # all.
87
88 # The precise terms and conditions for copying, distribution
89 # and modification follow.
90
91 # GNU GENERAL PUBLIC LICENSE
92 # TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND
93 # MODIFICATION
94
95 # 0. This License applies to any program or other work
96 # which contains a notice placed by the copyright holder
97 # saying it may be distributed under the terms of this
98 # General Public License. The "Program", below, refers to
99 # any such program or work, and a "work based on the Program"
100 # means either the Program or any derivative work under
101 # copyright law: that is to say, a work containing the
102 # Program or a portion of it, either verbatim or with
103 # modifications and/or translated into another language.
104 # (Hereinafter, translation is included without limitation in
105 # the term "modification".) Each licensee is addressed as
106 # "you".
107
108 # Activities other than copying, distribution and
109 # modification are not covered by this License; they are
110 # outside its scope. The act of running the Program is not
111 # restricted, and the output from the Program is covered only
112 # if its contents constitute a work based on the Program
113 # (independent of having been made by running the Program).
114 # Whether that is true depends on what the Program does.
115
116 # 1. You may copy and distribute verbatim copies of the
117 # Program's source code as you receive it, in any medium,
118 # provided that you conspicuously and appropriately publish
119 # on each copy an appropriate copyright notice and disclaimer
120 # of warranty; keep intact all the notices that refer to this
121 # License and to the absence of any warranty; and give any
122 # other recipients of the Program a copy of this License
123 # along with the Program.
124
125 # You may charge a fee for the physical act of transferring a
126 # copy, and you may at your option offer warranty protection
127 # in exchange for a fee.
128
129 # 2. You may modify your copy or copies of the Program or
130 # any portion of it, thus forming a work based on the
131 # Program, and copy and distribute such modifications or work
132 # under the terms of Section 1 above, provided that you also
133 # meet all of these conditions:
134
135 # a) You must cause the modified files to carry prominent
136 # notices stating that you changed the files and the date
137 # of any change.
138
139 # b) You must cause any work that you distribute or
140 # publish, that in whole or in part contains or is
141 # derived from the Program or any part thereof, to be
142 # licensed as a whole at no charge to all third parties
143 # under the terms of this License.
144
145 # c) If the modified program normally reads commands
146 # interactively when run, you must cause it, when started
147 # running for such interactive use in the most ordinary
148 # way, to print or display an announcement including an
149 # appropriate copyright notice and a notice that there is
150 # no warranty (or else, saying that you provide a
151 # warranty) and that users may redistribute the program
152 # under these conditions, and telling the user how to
153 # view a copy of this License. (Exception: if the
154 # Program itself is interactive but does not normally
155 # print such an announcement, your work based on the
156 # Program is not required to print an announcement.)
157
158 # These requirements apply to the modified work as a whole.
159 # If identifiable sections of that work are not derived from
160 # the Program, and can be reasonably considered independent
161 # and separate works in themselves, then this License, and
162 # its terms, do not apply to those sections when you
163 # distribute them as separate works. But when you distribute
164 # the same sections as part of a whole which is a work based
165 # on the Program, the distribution of the whole must be on
166 # the terms of this License, whose permissions for other
167 # licensees extend to the entire whole, and thus to each and
168 # every part regardless of who wrote it.
169
170 # Thus, it is not the intent of this section to claim rights
171 # or contest your rights to work written entirely by you;
172 # rather, the intent is to exercise the right to control the
173 # distribution of derivative or collective works based on the
174 # Program.
175
176 # In addition, mere aggregation of another work not based on
177 # the Program with the Program (or with a work based on the
178 # Program) on a volume of a storage or distribution medium
179 # does not bring the other work under the scope of this
180 # License.
181
182 # 3. You may copy and distribute the Program (or a work
183 # based on it, under Section 2) in object code or executable
184 # form under the terms of Sections 1 and 2 above provided
185 # that you also do one of the following:
186
187 # a) Accompany it with the complete corresponding
188 # machine-readable source code, which must be distributed
189 # under the terms of Sections 1 and 2 above on a medium
190 # customarily used for software interchange; or,
191
192 # b) Accompany it with a written offer, valid for at
193 # least three years, to give any third party, for a
194 # charge no more than your cost of physically performing
195 # source distribution, a complete machine-readable copy
196 # of the corresponding source code, to be distributed
197 # under the terms of Sections 1 and 2 above on a medium
198 # customarily used for software interchange; or,
199
200 # c) Accompany it with the information you received as to
201 # the offer to distribute corresponding source code.
202 # (This alternative is allowed only for noncommercial
203 # distribution and only if you received the program in
204 # object code or executable form with such an offer, in
205 # accord with Subsection b above.)
206
207 # The source code for a work means the preferred form of the
208 # work for making modifications to it. For an executable
209 # work, complete source code means all the source code for
210 # all modules it contains, plus any associated interface
211 # definition files, plus the scripts used to control
212 # compilation and installation of the executable. However,
213 # as a special exception, the source code distributed need
214 # not include anything that is normally distributed (in
215 # either source or binary form) with the major components
216 # (compiler, kernel, and so on) of the operating system on
217 # which the executable runs, unless that component itself
218 # accompanies the executable.
219
220 # If distribution of executable or object code is made by
221 # offering access to copy from a designated place, then
222 # offering equivalent access to copy the source code from the
223 # same place counts as distribution of the source code, even
224 # though third parties are not compelled to copy the source
225 # along with the object code.
226
227 # 4. You may not copy, modify, sublicense, or distribute
228 # the Program except as expressly provided under this
229 # License. Any attempt otherwise to copy, modify, sublicense
230 # or distribute the Program is void, and will automatically
231 # terminate your rights under this License. However, parties
232 # who have received copies, or rights, from you under this
233 # License will not have their licenses terminated so long as
234 # such parties remain in full compliance.
235
236 # 5. You are not required to accept this License, since you
237 # have not signed it. However, nothing else grants you
238 # permission to modify or distribute the Program or its
239 # derivative works. These actions are prohibited by law if
240 # you do not accept this License. Therefore, by modifying or
241 # distributing the Program (or any work based on the
242 # Program), you indicate your acceptance of this License to
243 # do so, and all its terms and conditions for copying,
244 # distributing or modifying the Program or works based on
245 # it.
246
247 # 6. Each time you redistribute the Program (or any work
248 # based on the Program), the recipient automatically receives
249 # a license from the original licensor to copy, distribute or
250 # modify the Program subject to these terms and conditions.
251 # You may not impose any further restrictions on the
252 # recipients' exercise of the rights granted herein. You are
253 # not responsible for enforcing compliance by third parties
254 # to this License.
255
256 # 7. If, as a consequence of a court judgment or allegation
257 # of patent infringement or for any other reason (not limited
258 # to patent issues), conditions are imposed on you (whether
259 # by court order, agreement or otherwise) that contradict the
260 # conditions of this License, they do not excuse you from the
261 # conditions of this License. If you cannot distribute so as
262 # to satisfy simultaneously your obligations under this
263 # License and any other pertinent obligations, then as a
264 # consequence you may not distribute the Program at all. For
265 # example, if a patent license would not permit royalty-free
266 # redistribution of the Program by all those who receive
267 # copies directly or indirectly through you, then the only
268 # way you could satisfy both it and this License would be to
269 # refrain entirely from distribution of the Program.
270
271 # If any portion of this section is held invalid or
272 # unenforceable under any particular circumstance, the
273 # balance of the section is intended to apply and the section
274 # as a whole is intended to apply in other circumstances.
275
276 # It is not the purpose of this section to induce you to
277 # infringe any patents or other property right claims or to
278 # contest validity of any such claims; this section has the
279 # sole purpose of protecting the integrity of the free
280 # software distribution system, which is implemented by
281 # public license practices. Many people have made generous
282 # contributions to the wide range of software distributed
283 # through that system in reliance on consistent application
284 # of that system; it is up to the author/donor to decide if
285 # he or she is willing to distribute software through any
286 # other system and a licensee cannot impose that choice.
287
288 # This section is intended to make thoroughly clear what is
289 # believed to be a consequence of the rest of this License.
290
291 # 8. If the distribution and/or use of the Program is
292 # restricted in certain countries either by patents or by
293 # copyrighted interfaces, the original copyright holder who
294 # places the Program under this License may add an explicit
295 # geographical distribution limitation excluding those
296 # countries, so that distribution is permitted only in or
297 # among countries not thus excluded. In such case, this
298 # License incorporates the limitation as if written in the
299 # body of this License.
300
301 # 9. The Free Software Foundation may
302 # publish revised and/or new versions of the General Public
303 # License from time to time. Such new versions will be
304 # similar in spirit to the present version, but may differ in
305 # detail to address new problems or concerns.
306
307 # Each version is given a distinguishing version number. If
308 # the Program specifies a version number of this License
309 # which applies to it and "any later version", you have the
310 # option of following the terms and conditions either of that
311 # version or of any later version published by the Free
312 # Software Foundation. If the Program does not specify a
313 # version number of this License, you may choose any version
314 # ever published by the Free Software Foundation.
315
316 # 10. If you wish to incorporate parts of the Program into
317 # other free programs whose distribution conditions are
318 # different, write to the author to ask for permission. For
319 # software which is copyrighted by the Free Software
320 # Foundation, write to the Free Software Foundation; we
321 # sometimes make exceptions for this. Our decision will be
322 # guided by the two goals of preserving the free status of
323 # all derivatives of our free software and of promoting the
324 # sharing and reuse of software generally.
325
326 # NO WARRANTY
327
328 # 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE
329 # IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
330 # APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING
331 # THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE
332 # PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
333 # EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
334 # IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
335 # PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
336 # PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
337 # PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
338 # SERVICING, REPAIR OR CORRECTION.
339
340 # 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR
341 # AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY
342 # OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM
343 # AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING
344 # ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
345 # ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
346 # (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
347 # RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
348 # PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY
349 # OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS
350 # BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
351
352 # END OF TERMS AND CONDITIONS
353
354
355
356
357 # How to Apply These Terms to Your New Programs
358
359 # If you develop a new program, and you want it to be of
360 # the greatest possible use to the public, the best way to
361 # achieve this is to make it free software which everyone can
362 # redistribute and change under these terms.
363
364 # To do so, attach the following notices to the program.
365 # It is safest to attach them to the start of each source
366 # file to most effectively convey the exclusion of warranty;
367 # and each file should have at least the "copyright" line and
368 # a pointer to where the full notice is found.
369
370 # /*
371 # <one line to give the program's name and a brief idea of what it does.>

388
389 # Also add information on how to contact you by electronic

392 # If the program is interactive, make it output a short

403 # course, the commands you use may be called something other
404 # than `show w' and `show c'; they could even be mouse-clicks
405 # or menu items--whatever suits your program.
406
407 # You should also get your employer (if you work as a

417 # Ty Coon, President of Vice
418
419 # This General Public License does not permit incorporating
420 # your program into proprietary programs. If your program is
421 # a subroutine library, you may consider it more useful to
422 # permit linking proprietary applications with the library.
423 # If this is what you want to do, use the GNU Library General
424 # Public License instead of this License.
