This tar.gz file contains:
desktop-login.ogg - the sound that plays after you have logged in.
desktop-logout.ogg - the sound that plays when you logout or power down.
system-ready.ogg - if only this were possible! This file uses the same voice in desktop-logout which states “Welcome! Please identify yourself.”
