      longDescription = ''
        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.
