 ## rabit: Reliable Allreduce and Broadcast Interface
 [![Build Status](https://travis-ci.org/dmlc/rabit.svg?branch=master)](https://travis-ci.org/dmlc/rabit)
 
-rabit is a light weight library that provides a fault tolerant interface of Allreduce and Broadcast. It is designed to support easy implementations of distributed machine learning programs, many of which fall naturally under the Allreduce abstraction. The goal of rabit is to support ***portable*** , ***scalable*** and ***reliable*** distributed machine learning programs.
