    "GMP is a library for arbitrary precision arithmetic, operating on
signed integers, rational numbers and floating point numbers.  The precision
is only limited by the available memory.  The library is highly optimized,
with a design focus on execution speed.  It is aimed at use in, for example,
cryptography and computational algebra.")
