 SUMMARY="GMP - GNU Multiple Precision Arithmetic Library" 
 DESCRIPTION="
-GMP - GNU Multiple Precision Arithmetic Library
+The GNU Multiple Precision Arithmetic Library (GMP) is a free library for \
+arbitrary-precision arithmetic, operating on signed integers, rational numbers, \
+and floating point numbers. There are no practical limits to the precision \
+except the ones implied by the available memory in the machine GMP runs on \
+(operand dimension limit is 2^(32)-1 bits on 32-bit machines and 2^37 bits on \
+64-bit machines). GMP has a rich set of functions, and the functions have a \
+regular interface. The basic interface is for C but wrappers exist for other \
+languages including Ada, C++, C#, OCaml, Perl, PHP, and Python. \
