+     Arb is a C library for arbitrary-precision interval arithmetic,
+     using a midpoint-radius representation (“ball arithmetic”). It
+     supports real and complex numbers, polynomials, power series,
+     matrices, and evaluation of many transcendental functions. All
+     operations are done with automatic, rigorous error bounds.
