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 (hex.pm, git, hg, and so on).
