IRC Away Command
You can use the /away command
to tell other users that you are still connected to IRC, but that you are away
from your terminal for a short while and can't read
messages right now.
If any user sends a message to you while the away command is on, then the server
will send them back a message to the effect that you are away, and they will know
that you are at least logged on, and can try again later.
