  53      "The libffi library provides a portable, high level programming interface
  54 to various calling conventions.  This allows a programmer to call any
  55 function specified by a call interface description at run-time.
  56
  57 FFI stands for Foreign Function Interface.  A foreign function interface is
  58 the popular name for the interface that allows code written in one language
  59 to call code written in another language.  The libffi library really only
  60 provides the lowest, machine dependent layer of a fully featured foreign
  61 function interface.  A layer must exist above libffi that handles type
  62 conversions for values passed between the two languages.")
