  10 Feb 2002; Karl Trygve Kalleberg <karltk@gentoo.org> ChangeLog files/digest-libffi-0.20 libffi-0.20:
  
  The libffi library provides a portable, high level programming interface to 
  various calling conventions. This allows a programmer to call any function 
  specified by a call interface description at run-time.

  Ffi stands for Foreign Function Interface. A foreign function interface is 
  the popular name for the interface that allows code written in one language 
  to call code written in another language. The libffi library really only 
  provides the lowest, machine dependent layer of a fully featured foreign 
  function interface. A layer must exist above libffi that handles type 
  conversions for values passed between the two languages.
