+      '' 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.
