libanyevent-websocket-client-perl 0.54-1 (s390x binary) in ubuntu kinetic

 AnyEvent::WebSocket::Client provides an interface to interact with a web
 server that provides services via the WebSocket protocol in an AnyEvent
 context. It uses Protocol::WebSocket rather than reinventing the wheel.
 You could use AnyEvent and Protocol::WebSocket directly if you wanted finer
 grain control, but if that is not necessary then this class may save you
 some time.
 .
 The recommended API was added to the AnyEvent::WebSocket::Connection
 class with version 0.12, so it is recommended that you include that
 version when using this module. The older version of the API has since
 been deprecated and removed.
