    longDescription = ''
      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).
