[gentoo-user] Can emerge play a sound on either a successful/unsuccessful build?

[Andrew Lowe]

Hi all,
	I have a laptop churning away in the loungeroom doing an "emerge -NuD
world" whilst I'm in my office, amongst other things composing this
email. If my world update fails, I won't know until I look at the screen
in the other room. Is there a way to get emerge to play a song depending
upon the status of the emerge build?

	If memory serves, an email can be sent letting you know what's
happening, but a sound would be better. For example, on those days when
you kick off an emerge then start pottering around the house doing
stuff. All of a sudden Wagner's "Ride of the Valkyries" starts playing,
and you know the emerge has karked it....

	Thoughts greatly appreciated,

		Andrew
