+define Package/libffi/description
+The libffi library provides a portable, high level programming interface to
+various calling conventions. This allows a programmer to call any function
+specified by a call interface description at run-time.
+
+FFI stands for Foreign Function Interface. A foreign function interface is the
+popular name for the interface that allows code written in one language to call
+code written in another language. The libffi library really only provides the
+lowest, machine dependent layer of a fully featured foreign function interface.
+A layer must exist above libffi that handles type conversions for values passed
+between the two languages.
