+ (description "The Littlewood-Richardson Calculator (lrcalc) is a
+program designed to compute Littlewood-Richardson coefficients. It computes
+single Littlewood-Richardson coefficients, products of Schur functions, or
+skew Schur functions. In addition it computes products in the small quantum
+cohomology ring of a Grassmann variety. The software package also includes
+a program that performs fast computation of the more general multiplicative
+structure constants of Schubert polynomials.")
