libcry-ocaml-dev binary package in Ubuntu Bionic amd64

 This OCaml module implements the protocols used to connect and
 send source data to icecast2 and shoutcast servers.
 .
 It is a low-level implementation, so it only does the minimal
 source connection. In particular, it does not handle synchronisation.
 Hence, the task of sending audio data to the streaming server
 at real time rate is up to the programmer, contrary to the main
 implementation, libshout.
