+SUMMARY="build tool that makes it easy to compile and test Erlang applications."
+DESCRIPTION="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).
