/*
 * Minimal example using lib/net/irc.fun
 *
 * This demo connects to an IRC server, registers, joins a channel, sends one
 * message, reads for a short while (responding to PINGs), then quits.
 *
 * TLS usage via local tunnel (recommended):
 *   1) Install stunnel and create a client service (example in repo docs).
 *   2) Run this script pointing to localhost:<local_tls_port>, use_tls=1.
