# this is a really hacky way to implement a notification setup for KDE and other
# systems that have notify-send installed. you can set it up via cronjob, or use
# KDE's 'notifications' manager to add a command to be executed whenever the
# screensaver is closed so you get a digest for what you have to work on today
