    See https://cwiki.apache.org/FLUME/getting-started.html for example configurations.
    Your flume config dir is #{libexec}/conf/

    If you intend to sink data to S3, you will need to download a missing JAR:
        wget -O #{libexec}/lib/jets3t-0.7.1.jar http://repo1.maven.org/maven2/net/java/dev/jets3t/jets3t/0.7.1/jets3t-0.7.1.jar

    system "#{bin}/flume-ng"
