+SUMMARY="A C++ library for efficient computations with arbitrary precision numbers"
+DESCRIPTION="CLN stands for Class Library for Numbers and is a library for \
+high-performance numeric computations with arbitrary precision. It is \
+implemented in C++ for high efficiency, type safety and nice syntax and \
+supports a wide range of types and functions that operate on them. It is \
+highly optimized in terms of both efficiency and speed and provides great \
+interoperability."
