+        PyERFA is the Python wrapper for the ERFA library (Essential Routines
+        for Fundamental Astronomy), a C library containing key algorithms for
+        astronomy, which is based on the SOFA library published by the
+        International Astronomical Union (IAU). All C routines are wrapped as
+        Numpy universal functions, so that they can be called with scalar or
+        array inputs.
