Introduction
is an alarm/reminder message scheduler. It lets you set up personal alarm/reminder messages which pop up on the screen at the time you specify.
In its default graphical mode, displays a list of pending alarms, showing their times and message texts. You can create new alarms, or alternatively you can select existing alarms in order to modify or delete them.
When setting up or modifying an alarm, you may either type in the alarm message text or specify a text file to display. You can also choose the colour of the alarm message, whether it should repeat, whether to sound an audible beep, and whether the alarm should be cancelled if it can't be displayed at its scheduled time.
Alarms may also be scheduled on the command line, or via calls from programs.
When an alarm message is due, it is displayed on each desktop to ensure that you don't miss it should you happen to be switching desktops just at that moment. The message window shows the time for which the alarm was scheduled, which could be useful to know if it was displayed late or if you were away from the computer when it popped up. It usually has a defer option to ask for the alarm to be displayed again later. An example of an alarm message:

Alarm message
can run in either of two modes: continuous (the default) where it runs from the system tray, or on-demand where it runs as and when required (with the option of displaying an independent system tray icon).
This document makes various references to the alarm daemon. This is an application which runs in the background, checking pending alarms and telling to display them when they become due.
