+     "Openspecfun provides AMOS and Faddeeva.  AMOS (from Netlib) is a
+portable package for Bessel Functions of a Complex Argument and Nonnegative
+Order; it contains subroutines for computing Bessel functions and Airy
+functions.  Faddeeva allows computing the various error functions of arbitrary
+complex arguments (Faddeeva function, error function, complementary error
+function, scaled complementary error function, imaginary error function, and
+Dawson function); given these, one can also easily compute Voigt functions,
+Fresnel integrals, and similar related functions as well.")
+    ;; Faddeeva is released under the Expat license; AMOS is included as
+    ;; public domain software.
