kidled is a Linux daemon that runs in the background,
looks for users who are idle for some time (20 minutes by default, can
be changed with an option), and logs them off.
There are no config files for kidled, it doesn't do
anything silly (no mail sent anywhere, just a message written on
user's terminal, no coffee made, no shutdown performed) and it's very
simple and reliable. All interesting and/or unusual events are logged
to syslogd.
