Marks you as "away". Whenever someone sends you a MSG or a does a whois on you, they automatically see whatever message you set. While you are away, all messages you receive will be timestamped and you will optionally get beeped (see set/beep_when_away) for each message. Using away with no parameters marks you as no longer being away.
Available Flags: -one Send away message to only the server in the current window. -all (default) send away message to all servers you may be on.
