5 SNNS is (Copyright) 1990-95 University of Stuttgart, Institute for
6 Parallel and Distributed High Performance Systems (IPVR),
7 Breitwiesenstr. 20-22, D-70565 Stuttgart, Fed. Rep. of Germany and
8 (Copyright) 1996-98 University of Tuebingen, Wilhelm-Schickard
9 Institute for Computer Science, Koestlinstr. 6, D-72074 Tuebingen.
11 SNNS is distributed by the University of Tuebingen as `Free Software'
12 in a licensing agreement similar in some aspects to the GNU General
13 Public License. There are a number of important differences, however,
14 regarding modifications and distribution of SNNS to third parties.
15 Note also that SNNS is not part of the GNU software nor is any of its
16 authors connected with the Free Software Foundation. We only share
17 some common beliefs about software distribution. Note further that
18 SNNS is NOT PUBLIC DOMAIN.
20 The SNNS License is designed to make sure that you have the freedom to
21 give away verbatim copies of SNNS, that you receive source code or can
22 get it if you want it and that you can change the software for your
23 personal use; and that you know you can do these things.
25 We protect your and our rights with two steps: (1) copyright the
26 software, and (2) offer you this license which gives you legal
27 permission to copy and distribute the unmodified software or modify it
30 In contrast to the GNU license we do not allow modified copies of our
31 software to be distributed. You may, however, distribute your
32 modifications as separate files (e.g. patch files) along with our
33 unmodified SNNS software. We encourage users to send changes and
34 improvements which would benefit many other users to us so that all
35 users may receive these improvements in a later version. The
36 restriction not to distribute modified copies is also useful to
37 prevent bug reports from someone else's modifications.
39 Also, for our protection, we want to make certain that everyone
40 understands that there is NO WARRANTY OF ANY KIND for the SNNS
43 If you have any questions regarding this license agreement, please

48 SNNS License Agreement
49 **********************************************************************
51 1. This License Agreement applies to the SNNS program and all
52 accompanying programs and files that are distributed with a notice
53 placed by the copyright holder saying it may be distributed under the
54 terms of the SNNS License. ``SNNS'', below, refers to any such
55 program or work, and a ``work based on SNNS'' means either SNNS or any
56 work containing SNNS or a portion of it, either verbatim or with
57 modifications. Each licensee is addressed as ``you''.
59 2. You may copy and distribute verbatim copies of SNNS's source code
60 as you receive it, in any medium, provided that you conspicuously and
61 appropriately publish on each copy an appropriate copyright notice and
62 disclaimer of warranty; keep intact all the notices that refer to this
63 License and to the absence of any warranty; and give any other
64 recipients of SNNS a copy of this license along with SNNS.
66 3. You may modify your copy or copies of SNNS or any portion of it
67 only for your own use. You may not distribute modified copies of SNNS
68 You may, however, distribute your modifications as separate files (e.
69 patch files) along with the unmodified SNNS software. We also
70 encourage users to send changes and improvements which would benefit
71 many other users to us so that all users may receive these
72 improvements in a later version. The restriction not to distribute
73 modified copies is also useful to prevent bug reports from someone
76 4. If you distribute copies of SNNS you may not charge anything except
77 the cost for the media and a fair estimate of the costs of computer
78 time or network time directly attributable to the copying.
80 5. You may not copy, modify, sublicense, distribute or transfer SNNS
81 except as expressly provided under this License. Any attempt
82 otherwise to copy, modify, sublicense, distribute or transfer SNNS is
83 void, and will automatically terminate your rights to use SNNS under
84 this License. However, parties who have received copies, or rights to
85 use copies, from you under this License will not have their licenses
86 terminated so long as such parties remain in full compliance.
88 6. By copying, distributing or modifying SNNS (or any work based on
89 SNNS) you indicate your acceptance of this license to do so, and all
90 its terms and conditions.
92 7. Each time you redistribute SNNS (or any work based on SNNS), the
93 recipient automatically receives a license from the original licensor
94 to copy, distribute or modify SNNS subject to these terms and
95 conditions. You may not impose any further restrictions on the
96 recipients' exercise of the rights granted herein.
98 8. Incorporation of SNNS or parts of it in commercial programs
99 requires a special agreement between the copyright holder and the
100 Licensee in writing and ususally involves the payment of license fees.
101 If you want to incorporate SNNS or parts of it in commercial programs
102 write to the author about further details.
104 9. Because SNNS is licensed free of charge, there is no warranty for
105 SNNS, to the extent permitted by applicable law. The copyright holders
106 and/or other parties provide SNNS ``as is'' without warranty of any
107 kind, either expressed or implied, including, but not limited to, the
108 implied warranties of merchantability and fitness for a particular
109 purpose. The entire risk as to the quality and performance of SNNS is
110 with you. Should the program prove defective, you assume the cost of
111 all necessary servicing, repair or correction.
113 10. In no event will any copyright holder, or any other party who may
114 redistribute SNNS as permitted above, be liable to you for damages,
115 including any general, special, incidental or consequential damages
116 arising out of the use or inability to use SNNS (including but not
117 limited to loss of data or data being rendered inaccurate or losses
118 sustained by you or third parties or a failure of SNNS to operate with
119 any other programs), even if such holder or other party has been
120 advised of the possibility of such damages.
