+      libmpdec is a fast C/C++ library for correctly-rounded arbitrary
+      precision decimal floating point arithmetic.  It is a complete
+      implementation of Mike Cowlishaw/IBM's General Decimal Arithmetic
+      Specification. The full specification is available here:
+
+      http://speleotrove.com/decimal/
+
+      libmpdec will - with minor restrictions - also conform to the IEEE
+      754-2008 Standard for Floating-Point Arithmetic, provided that the
+      appropriate context parameters are set.
+
+      libmpdec++ is a complete implementation of the General Decimal Arithmetic
+      Specification.  libmpdec++ is mostly a header library around libmpdec's C
+      functions.
