  58     (description
  59      "The libffi library provides a portable, high level programming interface
  60 to various calling conventions.  This allows a programmer to call any
  61 function specified by a call interface description at run-time.
  62
  63 FFI stands for Foreign Function Interface.  A foreign function interface is
  64 the popular name for the interface that allows code written in one language
  65 to call code written in another language.  The libffi library really only
  66 provides the lowest, machine dependent layer of a fully featured foreign
  67 function interface.  A layer must exist above libffi that handles type
  68 conversions for values passed between the two languages.")
