KAlarm lets you schedule personal messages to display, audio files to play, commands to execute, or emails to send. Among its options, it allows you to choose the message font and color, recurrence schedule, whether to display an advance reminder, whether to speak the message or play a sound when it is displayed, and whether to cancel the alarm if it can't be triggered on time (e.g. if you are logged out at the time). As well as using the graphical interface to configure alarms, you can use the command line, and there is a D-Bus/DCOP interface for other applications.
The "fmconv" script modifies the /etc/fstab file and the /boot/grub/menu.lst file to use either UUID strings or device filenames depending upon the parameter settings (-u or -d). This easy conversion to device filenames for maintenance purposes (UUID strings are hard to maintain, and just annoying), and the conversion back to UUID strings allows grub to work in an environment where the boot disk sequence is poorly defined by the BIOS. The original files are never overwritten.
