        Elixir is a functional, meta-programming aware language built on
        top of the Erlang VM. It is a dynamic language with flexible
        syntax and macro support that leverages Erlang's abilities to
        build concurrent, distributed and fault-tolerant applications
        with hot code upgrades.
