golang-github-armon-go-proxyproto-dev 0.0~git20190211.68259f7-2 (amd64 binary) in ubuntu hirsute

 This library provides the proxyproto package which can be used for
 servers listening behind HAProxy of Amazon ELB load balancers.
 Those load balancers support the use of a proxy protocol
 (http://haproxy.1wt.eu/download/1.5/doc/proxy-protocol.txt),
 which provides a simple mechansim for the server to get the address
 of the client instead of the load balancer.
 .
 This library provides both a net.Listener and net.Conn implementation that
 can be used to handle situation in which you may be using the proxy protocol.
 Only proxy protocol version 1, the human-readable form, is understood.
 .
 The only caveat is that one checks for the "PROXY " prefix to determine if
 the protocol is being used. If that string may occur as part of your input,
 then it is ambiguous if the protocol is being used and you may have problems.
