30		** This library is derived, with permission, from the International
31		** Astronomical Union's "Standards of Fundamental Astronomy" library,
32		** available from http://www.iausofa.org.
33		**
34		** The ERFA version is intended to retain identical functionality to
35		** the SOFA library, but made distinct through different function and
36		** file names, as set out in the SOFA license conditions. The SOFA
37		** original has a role as a reference standard for the IAU and IERS,
38		** and consequently redistribution is permitted only in its unaltered
39		** state. The ERFA version is not subject to this restriction and
40		** therefore can be included in distributions which do not support the
41		** concept of "read only" software.
42		**
43		** Although the intent is to replicate the SOFA API (other than
44		** replacement of prefix names) and results (with the exception of
45		** bugs; any that are discovered will be fixed), SOFA is not
46		** responsible for any errors found in this version of the library.
47		**
48		** If you wish to acknowledge the SOFA heritage, please acknowledge
49		** that you are using a library derived from SOFA, rather than SOFA
50		** itself.
