description         libffi provides a high level api to various calling conventions
long_description    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. \
                    Some programs may not know at the time of compilation \
                    what arguments are to be passed to a function. For \
                    instance, an interpreter may be told at run-time about \
                    the number and types of arguments used to call a given \
                    function. Libffi can be used in such programs to \
                    provide a bridge from the interpreter program to \
                    compiled code.
