// Solution to part 2 of the Whispering Gophers code lab.
//
// This program extends part 1.
//
// It makes a connection the host and port specified by the -dial flag, reads
// lines from standard input and writes JSON-encoded messages to the network
// connection.
//
// You can test this program by installing and running the dump program:
// 	$ go get github.com/campoy/whispering-gophers/util/dump
// 	$ dump -listen=localhost:8000
// And in another terminal session, run this program:
// 	$ part2 -dial=localhost:8000
// Lines typed in the second terminal should appear as JSON objects in the
// first terminal.
//
