47** SOFA Software License
48** =====================
49**
50** NOTICE TO USER:
51**
52** BY USING THIS SOFTWARE YOU ACCEPT THE FOLLOWING SIX TERMS AND
53** CONDITIONS WHICH APPLY TO ITS USE.
54**
55** 1. The Software is owned by the IAU SOFA Board ("SOFA").
56**
57** 2. Permission is granted to anyone to use the SOFA software for any
58** purpose, including commercial applications, free of charge and
59** without payment of royalties, subject to the conditions and
60** restrictions listed below.
61**
62** 3. You (the user) may copy and distribute SOFA source code to others,
63** and use and adapt its code and algorithms in your own software,
64** on a world-wide, royalty-free basis. That portion of your
65** distribution that does not consist of intact and unchanged copies
66** of SOFA source code files is a "derived work" that must comply
67** with the following requirements:
68**
69** a) Your work shall be marked or carry a statement that it
70** (i) uses routines and computations derived by you from
71** software provided by SOFA under license to you; and
72** (ii) does not itself constitute software provided by and/or
73** endorsed by SOFA.
74**
75** b) The source code of your derived work must contain descriptions
76** of how the derived work is based upon, contains and/or differs
77** from the original SOFA software.
78**
79** c) The names of all routines in your derived work shall not
80** include the prefix "iau" or "sofa" or trivial modifications
81** thereof such as changes of case.
82**
83** d) The origin of the SOFA components of your derived work must
84** not be misrepresented; you must not claim that you wrote the
85** original software, nor file a patent application for SOFA
86** software or algorithms embedded in the SOFA software.
87**
88** e) These requirements must be reproduced intact in any source
89** distribution and shall apply to anyone to whom you have
90** granted a further right to modify the source code of your
91** derived work.
92**
93** Note that, as originally distributed, the SOFA software is
94** intended to be a definitive implementation of the IAU standards,
95** and consequently third-party modifications are discouraged. All
96** variations, no matter how minor, must be explicitly marked as
97** such, as explained above.
98**
99** 4. You shall not cause the SOFA software to be brought into
100** disrepute, either by misuse, or use for inappropriate tasks, or
101** by inappropriate modification.
102**
103** 5. The SOFA software is provided "as is" and SOFA makes no warranty
104** as to its use or performance. SOFA does not and cannot warrant
105** the performance or results which the user may obtain by using the
106** SOFA software. SOFA makes no warranties, express or implied, as
107** to non-infringement of third party rights, merchantability, or
108** fitness for any particular purpose. In no event will SOFA be
109** liable to the user for any consequential, incidental, or special
110** damages, including any lost profits or lost savings, even if a
111** SOFA representative has been advised of such damages, or for any
112** claim by any third party.
113**
114** 6. The provision of any version of the SOFA software under the terms
115** and conditions specified herein does not imply that future
116** versions will also be made available under the same terms and
117** conditions.
118*
119** In any published work or commercial product which uses the SOFA
120** software directly, acknowledgement (see www.iausofa.org) is
121** appreciated.
