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.
