58             ** available from http://www.iausofa.org.
59             **
60             ** The ERFA version is intended to retain identical functionality to
61             ** the SOFA library, but made distinct through different function and
62             ** file names, as set out in the SOFA license conditions. The SOFA
63             ** original has a role as a reference standard for the IAU and IERS,
64             ** and consequently redistribution is permitted only in its unaltered
65             ** state. The ERFA version is not subject to this restriction and
66             ** therefore can be included in distributions which do not support the
67             ** concept of "read only" software.
68             **
69             ** Although the intent is to replicate the SOFA API (other than
70             ** replacement of prefix names) and results (with the exception of
71             ** bugs; any that are discovered will be fixed), SOFA is not
72             ** responsible for any errors found in this version of the library.
73             **
74             ** If you wish to acknowledge the SOFA heritage, please acknowledge
75             ** that you are using a library derived from SOFA, rather than SOFA
76             ** itself.
