;;; This is the sub-collection for the special functions provided by the 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.

;;;                    special-functions for Release 1.0. (MDW)
;;; 1.1.0    02/09/06  Added beta and exponential integral functions. (MDW)
