+ This is a suite of vector/matrix routines and various utilities that
+ underpin the astronomy algorithms, which include routines for the
+ following:
+ * Calendars
+ * Time Scales
+ * Earth rotation and sidereal time
+ * Ephemerides (medium precision)
+ * Geocentric/geodetic transformations
+ * Precession, nutation, polar motion
+ * Star space motion
+ * Star catalogue conversion
+ This is the ANSI C version of the library.
+ The International Astronomical Union's SOFA service has the task of
+ establishing and maintaining an accessible and authoritative set of
+ algorithms and procedures that implement standard models used in
+ fundamental astronomy.
