      rebar is a self-contained Erlang script, so it's easy to
      distribute or even embed directly in a project. Where possible,
      rebar uses standard Erlang/OTP conventions for project
      structures, thus minimizing the amount of build configuration
      work. rebar also provides dependency management, enabling
      application writers to easily re-use common libraries from a
      variety of locations (git, hg, etc).
