  96      "The libffi library provides a portable, high level programming interface
  97 to various calling conventions.  This allows a programmer to call any
  98 function specified by a call interface description at run-time.
  99
 100 FFI stands for Foreign Function Interface.  A foreign function interface is
 101 the popular name for the interface that allows code written in one language
 102 to call code written in another language.  The libffi library really only
 103 provides the lowest, machine dependent layer of a fully featured foreign
 104 function interface.  A layer must exist above libffi that handles type
 105 conversions for values passed between the two languages.")
