Features:

Installable via go get
go get -u github.com/mastercactapus/proxyprotocol// Create any net.Listener
l, err := net.Listen("tcp", ":0")
l, err := net.Listen("udp", ":0")
l, err := net.Listen("unix", "/tmp/example")
l, err := net.Listen("unixgram", "/tmp/example")
// Wrap it to have RemoteAddr() and LocalAddr() resolved for all new connections
l = proxyprotocol.NewListener(l, 0)
c, err : = l.Accept()
c.RemoteAddr() // = The PROXY header source address
c.LocalAddr() // = The PROXY header destination address
