38** This library is derived, with permission, from the International
39** Astronomical Union's "Standards of Fundamental Astronomy" library,
40** available from http://www.iausofa.org.
41**
42** The ERFA version is intended to retain identical functionality to
43** the SOFA library, but made distinct through different function and
44** file names, as set out in the SOFA license conditions. The SOFA
45** original has a role as a reference standard for the IAU and IERS,
46** and consequently redistribution is permitted only in its unaltered
47** state. The ERFA version is not subject to this restriction and
48** therefore can be included in distributions which do not support the
49** concept of "read only" software.
50**
51** Although the intent is to replicate the SOFA API (other than
52** replacement of prefix names) and results (with the exception of
53** bugs; any that are discovered will be fixed), SOFA is not
54** responsible for any errors found in this version of the library.
55**
56** If you wish to acknowledge the SOFA heritage, please acknowledge
57** that you are using a library derived from SOFA, rather than SOFA
58** itself.
