44		** available from http://www.iausofa.org.
45		**
46		** The ERFA version is intended to retain identical functionality to
47		** the SOFA library, but made distinct through different function and
48		** file names, as set out in the SOFA license conditions. The SOFA
49		** original has a role as a reference standard for the IAU and IERS,
50		** and consequently redistribution is permitted only in its unaltered
51		** state. The ERFA version is not subject to this restriction and
52		** therefore can be included in distributions which do not support the
53		** concept of "read only" software.
54		**
55		** Although the intent is to replicate the SOFA API (other than
56		** replacement of prefix names) and results (with the exception of
57		** bugs; any that are discovered will be fixed), SOFA is not
58		** responsible for any errors found in this version of the library.
59		**
60		** If you wish to acknowledge the SOFA heritage, please acknowledge
61		** that you are using a library derived from SOFA, rather than SOFA
62		** itself.
