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