golang-github-pierrec-lz4-dev 2.5.2-2 (s390x binary) in ubuntu lunar

 This library implements reading and writing lz4 compressed data (a frame),
 as specified in
 http://fastcompression.blogspot.fr/2013/04/lz4-streaming-format-final.html,
 using an io.Reader (decompression) and io.Writer (compression). It is
 designed to minimize memory usage while maximizing throughput by being
 able to [de]compress data concurrently.
