This is off-the-cup and incomplete, but you get the idea.

cd()
{
        about=false
        case "$1" in
        --about)        about=true ; shift ;;
        esac

        builtin cd "$@"
        rv=$?

        (( $rv == 0 )) && $about && [ -f .__about__ ] && cat .__about__

        return $rv
}

We don't need to be so eager to embed this kind of stuff in C code.
