    (description
-    "GMP is a free library for arbitrary precision arithmetic, operating on
-signed integers, rational numbers, and floating point numbers.  There is no
-practical limit to the precision except the ones implied by the available
-memory in the machine GMP runs on.  GMP has a rich set of functions, and the
-functions have a regular interface.
-
-The main target applications for GMP are cryptography applications and
-research, Internet security applications, algebra systems, computational
-algebra research, etc.
-
-GMP is carefully designed to be as fast as possible, both for small operands
-and for huge operands.  The speed is achieved by using fullwords as the basic
-arithmetic type, by using fast algorithms, with highly optimised assembly
-code for the most common inner loops for a lot of CPUs, and by a general
-emphasis on speed.
-
-GMP is faster than any other bignum library.  The advantage for GMP increases
-with the operand sizes for many operations, since GMP uses asymptotically
-faster algorithms.")
