;;; This is the sub-collection for the special functions provided by
;;; the PLT Scheme Science Collection.  These include:
;;;   - Error Functions
;;;   - Gamma Functions
;;;   - Psi (Digamma) Functions
;;;   - Zeta Functions
;;;   - Beta Functions
;;;   - Exponential Integral Functions
;;; Note that the Gamma, Psi, and Zeta routines are provided as a
;;; single module.  This is because their definition are interdependent
;;; and would result in circular modules.  Individual modules are
;;; available (as gamma.ss, psi.ss, and zeta.ss in the special-
;;; functions sub-collection), but they all load the combined file and
;;; provide just the corresponding routines from it.
;;;
;;; Version Date      Description
;;; 1.0.0   09/20/04  Marked as ready for Release 1.0.  Includes all of
;;;                   the special-functions for Release 1.0.  (Doug
;;;                   Williams)
;;; 1.1.0   02/09/06  Added beta and exponential integral functions.
;;;                   (Doug Williams)
;;; 3.0.0   06/09/08  Changes required for V4.0.  (Doug Williams)
