Many people (including myself) bundle pre-built rebar in the repository
out of convenience, but it could hardly be considered best practice from
technical point of view -- due to ERTS' compatibility contract on BEAM
bytecode versions by including pre-built rebar we also implicitly dictate
the maximum Erlang version that will be able to build our project. If we
were to ever upgrade the pre-built rebar file we'd on the other hand
dictate minimum supported Erlang version.

Probably not what anybody really wants in the long run, I suppose?
Perhaps best to require rebar as a build-time dependency if you want
to play safe?
