+Ruby-FFI is a ruby extension for programmatically loading dynamic
+libraries, binding functions within them, and calling those functions
+from Ruby code. Moreover, a Ruby-FFI extension works without changes
+on Ruby and JRuby. Discover why should you write your next extension
+using Ruby-FFI here: http://wiki.github.com/ffi/ffi/why-use-ffi
