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