  DESCRIPTION:=\
	GNU MP is a portable library written in C for arbitrary precision \\\
	arithmetic on integers, rational numbers, and floating-point \\\
	numbers. It aims to provide the fastest possible arithmetic for \\\
	all applications that need higher precision than is directly \\\
	supported by the basic C types.
