+      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).
