A program to notify the user when other one logs in. Notifyme is a console
utility that stays in a background (it isn't a daemon but it doesn't
block terminal) and prints a message if a specified login and/or logout
occurs. In a resource file ($HOME/notify.rc by default)
you can specify (extended regular expressions are allowed) usernames,
hostnames and terminals that should be monitored, optional messages
that will be displayed and other options (beep, report logouts etc.)
