+   (description
+    "FLINT is a C library for number theory.  It supports arithmetic
+with numbers, polynomials, power series and matrices over many base
+rings, including multiprecision integers and rationals, integers
+modulo n, p-adic numbers, finite fields (prime and non-prime order)
+and real and complex numbers (via the Arb extension library).
+
+Operations that can be performed include conversions, arithmetic,
+GCDs, factoring, solving linear systems, and evaluating special
+functions.  In addition, FLINT provides various low-level routines for
+fast arithmetic.")
