+    "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.")
