  67      "The libffi library provides a portable, high level programming interface
  68 to various calling conventions.  This allows a programmer to call any
  69 function specified by a call interface description at run-time.
  70
  71 FFI stands for Foreign Function Interface.  A foreign function interface is
  72 the popular name for the interface that allows code written in one language
  73 to call code written in another language.  The libffi library really only
  74 provides the lowest, machine dependent layer of a fully featured foreign
  75 function interface.  A layer must exist above libffi that handles type
  76 conversions for values passed between the two languages.")
