Erlang build tool that makes it easy to compile and test Erlang applications and releases.

Rebar3 is an Erlang tool that makes it easy to create, develop, and release Erlang libraries, applications, and systems in a repeatable manner.

Rebar3 is not Rebar - as the two are completely different.

Rebar3 is also a self-contained Erlang script. It is easy to distribute or embed directly in a project. Tasks or behaviours can be modified or expanded with a plugin system flexible enough that even other languages on the Erlang VM will use it as a build tool.
