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