-        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.
