(description
"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.")
