Rebar is an Erlang build tool that makes it easy to compile and test Erlang applications, port drivers and releases.
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).
