+    longDescription = ''
+      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.
